Intel 486SX-16MHz Benchmark and Upgrade to Kingston Turbochip at 133MHz (AMD 5x86-133)

[@mikeall7012]

We got that exact upgrade for our packard bell legend 25mhz sx. The performance boost was huge. It was like getting a whole new computer. We upgraded from 4 to 16 mb of ram and put in a sb16 and cdrom too.

[@idadru]

I remember my first CD-ROM, I had to use the ide port that was on the sound card 😔

[@memadmax69]

The good ol days lol

[@floodo1]

Hello fellow 25mhz SX user. My grandpa gifted me what must have been the cheapest IBM at the time because it only had TWO megabytes of ram and the CPU wasn’t socketed so no dream upgrades like this haha. It let me get on local BBS tho and the rest is history!

[@floodo1]

686 was my fav btw

[@DevilbyMoonlight]

@@idadru back then there were 3x CD-Rom interfaces on sound cards, dont be fooled that they are IDE, the Sony, Mitsumi & the Panasonic - IDE CDRoms came later and didnt need the audio cable after DAE became a thing.. I preferred the Panasonic drives back then no messing around and worked without issues, the sony ones were the most problematic, they didnt even have a motorised tray lol they just spat the tray out half way under spring pressure... lol

[@johncate9541]

Not half as amazing as it was to do this exact same upgrade in 1998. It was literally like having a whole new computer.

I love this, thank you so much for all your work and cool videos!!!

[@CPUGalaxy]

Thank you 🙏🏻

[@necro_ware]

Thank you very much for the shout out and for this video. Very exciting, as always. That Kingston CPU is very funny, not only they didn't bother to use a heat spreader, but they also glued the fan directly on the chip, so it blows only at the edges, but the die in the middle is where no air is coming to :D I'm impressed to see this CPU, since it is very rare, but I'm a little bit confused by the engineering job Kingston did on that :D

[@CPUGalaxy]

You are welcome! For me I can say your channel is the best retro channel out there! And I was also very surprised about the cooling engineering on the Kingston. 😅

[@britlion]

Ooh, another fun retro upgrade challenge. It's awesome to see you doing new content. Thank you!

[@UpLateGeek]

That's just about the biggest upgrade possible without changing the motherboard! The first PC upgrade I bought was an AMD 5x86-133 for my family's old 486. I also replaced the motherboard since the new one had PCI slots, which also allowed me to upgrade the video card. And I also played a lot of Doom, Doom II, and Duke 3D on that machine! I do like the look of those memory modules you used. The blobs over the chips are a little ugly, but the look of the PCB makes up for it, and it does mean they're very low-profile, which is also nice. I recently soldered up some new modules based on some NOS Toshiba chips I bought from the US America last year and some other NOS Mitsubishi chips I bought from eBay in 2020 for the parity bit, using an updated version of my 4MB memory module design. While the modules failed testing in my SIMCheck, it was just the parity bit, and the Toshiba memory tested fine at 40ns despite being rated at 60ns. These would be very good for overclocking if I can figure out why the parity bits failed (or just use them without the parity bit chips). It's possible I just happened to get a couple of bad chips in a row, so I designed some modules that took SOJ test sockets which would allow me to test all the chips before soldering them onto the modules. I also ordered them from the US America, but they sent me sockets that took 0.35" wide chips instead of 0.3", so they don't work. I think I might have to order the sockets from a genuine reseller in Europe or the UK, rather than some random dodgy website in the US America. But such is the trials and tribblations of designing electronics for vintage computers.

[@TrashfordKent]

excellent thank you, like you've mentioned an 486SX 16 vs 386 DX33/40 would be very interesting.

[@xidarian]

I used to have this exact chip. I upgraded a 25mhz 486 with this and it was a huge upgrade.

[@Damien.D]

Pretty fun to have both lowest end and then upmost end of processors of this socket running on the same board.

[@skyhawk21]

Thanks great video brings back memories of the good all days I had a 386 and upgraded to a 486 so I could play .mp3 files smoothly and multi task in windows.. then a 586 and Cyrix 686 for gaming.. Today I have an awesome 13900k system with ddr5 and it blows my mind what technology can do today. I can’t even max out the system for productivity or leisure… back during the golden era of computers, playing a single .mp3 file with Winamp, would max out cpu!!!!

[@Thomsonicus]

If someone made a change like that in 1996 I imagine it would be shocking how diffrent that computer would feel.

[@5roundsrapid263]

Seriously… It made it 4-5x faster in a few minutes. No wonder Overdrive/Turbochip upgrades sold like hotcakes. You’d save at least $1000, which is about $2000 today!

[@rsmith02]

If they're using this in 1996 I'd feel bad for them. Pentium II was out by 97.

[@soylentgreenb]

I remember pentium 2 being just stupidly expensive when released. It was much cheaper by 1998. Same with pentium; the P60 and P66 was very expensive and almost nobody had one.

[@drxym]

I upgraded my first PC from a 486 SX 25, to a DX 33, to a DX2 66 to a DX4 100. Yes it made stuff faster but it's a law of diminishing returns because the rest of the system like the bus, memory, storage etc becomes the bottle neck. I still got 4 or so years out of it, upgrading bits and pieces until I did a reset for my move to Pentium.

[@soylentgreenb]

@@drxym For games I'm not sure anything above the DX 33 helped if you had some horrid trident ISA graphics thing. If you have a really fast ISA card I think you'd still see gains from the DX-2/66 and above that you'd really want a VLB or PCI card (some very late 486 motherboards actually had this). You'd still get a higher score in FPU intensive stuff, but you can't really play those games comfortably anyway on a 486 (e.g. Quake). You'd also want L2 when you're getting up there in speeds, which many cheaper 486s didn't come with.

[@Shmbler]

I loved the subtle background music that you faded in with Norton Sysinfo. It really built up some tension. But then it prematurely ended ;-) No 160MHz today? 40MHz FSB really make all the difference in the world for L2 and mem throughput. And 10x the speed CPU upgrade would also be pretty unique ;-)

[@tomiluukkonen4035]

Glad you're back! Unsubscribed just maybe 3-4 weeks ago when I finally assumed that Channel was done :( So happy to see you again, keep up the good work :) btw; your 486SX/16 was most likely SO heavily CPU-limited that no amount of tuning won't help. Tuned a lot of early PC's since 1987 and seen a lot of quirks in 1990's and some chipsets behaved very strangely. 11MHz AT-bus _should_ help a lot but with 486SX/16... apparently not.

[@tomiluukkonen4035]

Is there any software to tune that 5x86 Kingston you tested? You can only go so far with AT-bus overclocking until MB goes unstable. Sadly Overdrive-Pentiums were pricey even then. I later had Cyrix CPU's quite a while and those had a lot of tuning-sw available.

[@BrassicGamer]

Imagine having that 16MHz 486 back then, and spending hundreds of pounds on cache and RAM... and seeing no improvement. I was impressed by the number of tweaks on this motherboard, though. It would be amazing with VLB included. Thanks for the video!

[@Swarl281]

The way you said quadrupled actually makes more sense than the actual way its said. Very nice video like watching these retro tech (well retro to me) videos keep it up.

[@oggilein1]

I Recently got given two 486 cpus by a friend of mine along with a bunch of other cool tech (including an old 5:4 monitor that actually ended up replacing my newer 16:9 one due to just how good the image quality is) that he "had no use for anymore" I was thinking about selling them but after discovering this channel I'm now convinced to get them running someday, thanks for the inspiration!

[@McTroyd]

Love seeing epic performance boosts! In those days I was running a 12 MHz 286, and would have given anything for that kind of machine. Also, FYI, "quadrupled" (kwah-DREW-pulled) means "multiplied by four." In the context of CPU clocks, I understand this is usually clocked by a PLL (phase-locked loop) oscillator. Makes sense, given you're going from ~33 MHz to ~133 MHz. 👍

[@nixosianarrt2419]

Had a "super 286" running @ 16mhz ... fondly remember that machine , playing Falcon 1.0. Then I got a cheap 386SX which was still a better machine.

[@CPU-Z]

Very interesting. I totally share what you said concerning the benchs results that are strictly identical after the BIOS optimization, I've faced the exact same effects on several systems, and jut can't explain why. The 486SX-16 became a piece of collection, pretty hard to find on eBay (at a reasonnable price of course). And so does the Turbochip !

5:53 Such memories... I had this bios in my first pc in 1993 (386 dx 40mhz). It is funny feeling, when you're messing with settings there, which I still remember.

[@HardQare]

Impressive setup. In the old days I owned a 486SX-25 I could easily OC to 40 MHz. I also upgraded ram from 4MB to 8MB. The graphic card was a Cirrus Logic 5428 VLB. It performed so well so I played through Blizzard Diablo.

[@Zytiron]

I still play Diablo on my system, though it's an AMD-DX4 100Mhz. I unfortunately "popped" my 486-25 trying to overclock (was still learning). lol

[@humidbeing]

I had a Kingston 133 in my Packard Bell when I was a kid. It made later DOS games run so much better. Great video! I subscribed!

[@Choralone422]

Upgrading my 486 DX2 66mhz to a AMD 5x86 133 running at 120mhz (due to a strange board issue that would only apply a 3x multiplier instead of 4x) was a good upgrade for my 1st PC. I also use a 5volt to 3.3 volt socket adapter in my setup and bought all the parts individually before Kingston started selling the Turbochip upgrades in the US. I still miss that 486 machine. I used it for a little over 5 years in all!

[@5roundsrapid263]

You could have gotten 150 MHz out of it easily, if your board supported a 50 MHz bus. I’ve heard that was common.

[@Choralone422]

@@5roundsrapid263 40mhz was the max bus speed on that board. It was a strange gimped PC but I made the most I could out of it.

[@5roundsrapid263]

[@laz7354]

From 386 level performance to Pentium level! Amazing upgrade.

[@johncate9541]

It was. AMD actually marketed the chip as "PR75," meaning in integer operations at least, it could match a 75 MHz Pentium. The Cyrix 5x86 could interface with a 486 socket and was faster, but had major compatibility issues. The AMD part was just a really fast 486 and could be made to work in any 486 socket. If you had an old board that couldn't support 3.45v operation, this TurboChip had the onboard regulator, and used the excess to power the fan.

[@GMCLabs]

My 1st PC had the same CPU, only it was 25Mhz. Eventually, I upgraded to the 83Mhz pentium overdrive CPU, though I think I had to run it at 63Mhz bc that was the highest speed the board supported. It was a Packard Bell PC. It was cool because I remember using the built-in tutorials to learn DOS commands and how to copy disks,files, and stuff.

[@SeeJayPlayGames]

locked 2.5x multiplier on the Pentium OverDrive. A 33MHz (66Mhz?) crystal oscillator transplant would have gotten you to 83.

[@TyrKohout]

Welcome back! I am so happy to see your excellent videos back on my feed.

[@laurdy]

An interesting comparison would be 286-16 vs 386-16 vs 486-16. It would also be interesting to see the weitek 4167 up against the 5x86-133 - especially the weitek benchmark programs.

[@nixosianarrt2419]

olden golden memories - the weitek... 5x86... Weitek equipped boards had a thing with the Xcom IIRC. I dont know, not I can imagine why. They loaded the above 640K memory loaded correctly but then froze when the XCOM started. Same with Xcom 2.

[@fungo6631]

The 486-16 is more or less on par with the 386-DX40

[@sebastian19745]

In advanced tab on BIOS setup, what the option "80486 DX2 CPU (50MHz)" does? It force the FSB to 50MHz? And if so, you can get the CPU to run at 150 MHz? What POST card do you use? I never seen one so tiny. You can populate Banks 2 and 3 (72 pin) RAM to increase the max amount of memory (4/16 M 32 pin RAM sticks are hard to find) and make a nice Win 95 machine...

[@utubeuser1024]

I was lucky enough to own one of the Turbochips back in the day - I installed it for a friend who was still running a 486SX/33 in 2005 and didn't want to throw it away as it worked for their needs - the performance increase was amazing - gave it a new lease of life!

That beep had me laughing. Great video!

[@ghydda]

Lovely video, congrats. However I think the slow graphics performance on the original CPU was partly due to the clock divider was set to run the ISA bus at a 1/3 of the system memory clock, and once the system got switched to 33MHz, the ISA bus got a very needed boost as well.

[@Kikay0n]

Thanks for the good memories… I miss those days

[@StrangelyIronic]

I built a couple 386 and 486 machines using parts salvaged from the computer/storage room at my dad's office back in the late 90s, but at home I learned programming and computers in general on already an old but still fun Apple IIGS and Mac IIci, both loaded with the best upgrades you could get because they were gifted from my uncle that saved them from the design and printing place he managed the computers for. I missed out a lot on DOS and Win 3.1/95 and when we did build a computer for be at home I went straight to a Pentium and 98SE. That said, I still use the IIGS and IIci for fun programming but haven't really gone back to older PC stuff (love videos on it though). I never played a ton of games, I just read books on Assembly and C, the two options I had the tools for on both, so I don't have the same nostalgia a lot of people do. I focused more on writing graphics/music programs, my own games, and IIGS demos.

[@jeremygeorgia4943]

The TurboChip actually IS based on a low powered laptop chip, as you mentioned. It has a small spreader on top of the chip. It's a small piece of metal that's embedded in the top, and it's flush with the rest of the chip. It runs slightly warm. (not hot) You technically probably don't even need a fan - even under load. In my experience, it runs slightly slower than a full 5x86 133, but it's still very fast for a 486 class chip. I think those boards were for 286 users, that still considered high end 386 computers expensive, but wanted to start with a 486. I think they were pretty inexpensive. You also got the prospect of future upgradeability. I am currently using one in a computer that was designed around a DX 33, so the Kingston dropped in & ran just fine. There were some Cyrix options, but they occasionally ran into timing problems.

[@phazonclash]

I upgraded my 486DX-33 back in the days with one of these CPUs. Big improvement indeed ;)

[@osgrov]

Very nice, those Turbochips are quite amazing. :) Were those 16MHz chips some sort of OEM special thing, do we know? I worked at a PC-builder in the early 90s and the cheapest chips we could buy was the SX-25. Never did see a 16 and we bought our parts from a huge distributor so if it was available they would've had it. At the time our entry-level PC used AMD 386DX-40, which I'm still fond of today. It wasn't that much slower than the 486-25 as I recall, and the 486 setup cost a lot more.

[@ph0end]

Yeah, you'd surely view a 100% ISA board as low-end, but it also has a whopping 8 SIMM slots, something I only saw on more expensive boards, and one of the more configurable examples of AMI BIOS. An industrial application makes the most sense to me, somewhere expansion was important, but clock speed wasn't. At the same time though, this era produced some weird and wonderful things, and it wouldn't shock me to learn it was from a name-brand desktop offering.

[@fungo6631]

Possibly in some applications that required performance a bit better than 386 performance but lower power and some more features. I'm pretty sure that the 486SX-16 consumed less power than a 386DX-40. I could see it being used in laptops. And regarding the price, note that Intel reduced the price of the 486SX once the Cyrix 486SLC was released in 1992. To 119 USD, no less.

[@elementbr]

I'm English an quadrupled still trips me up occasionally - you did a good effort.

[@Zerbey]

Really interesting upgrade, but yeah the ISA bus is definitely causing the CPU some bottlenecks! I would have loved an upgrade like this in the early 1990s when I had a 486-33. By 1996 I was using an AMD 5x86-133 (OC to 160Mhz) in a motherboard with a proper PCI bus and it performed extremely well.

I know only two first settings on the top - and rest of it below - It was always the mystery for me - what it is doing...- In 1996 I had access to internet in school for the first time, but I never checked it, and forget it later. but now, when you set up those settings with commentary (it looks like you know what you are doing) - it is such a nice feeling, to finally understand it better.

[@johnbee1574]

love the videos hope your all ok over there

[@SianaGearz]

Funny thing, while Duke doesn't care about FPU performance, if you don't have an FPU you're not going to have a good time in some very specific spots of some of the maps. That's because slope rendering code does an integer FPU load and then store back as a float to then do some further integer magic on that, looks like approximate 1/z calculation, and it does this once per pixel. That's the only FPU instruction used and it's basically non-arithmetic. This function that does this is also called to generate random numbers or something like that but not enough to matter for performance. There's also no alternative implementation for any of this, so if you don't have an FPU, you get it emulated by the Watcom runtime, handling the NM exception, which is predictably slow.

[@wskinnyodden]

PLEASE PLEASE TRY!!!! !!! !!! !!! I HAVE A REQUEST!!!! Please can you check if you can run a 486DX or above (any 486 including the FPU instead of the SX models) AND try to also install a Weitek CPU on it and see if you can run both FPUs on the system at the same time! Considering how they interface differently with the system this is likely possible and would be absolutely AWESOME. In case you did not know, Quake in particular had the performance it had on Intel CPUs because it could use the CPU's integer math at the same time as the FPU floating point calculations resulting in something akin to a dual core when it came to mathematics, this would not work on Cyrix as when the FPU math was in use the integer part was pretty much disabled/waiting for the FPU to finish therefore crippling the max performance. I would ask Quake developers directly (if I knew them) to actually extend the work they did and add support for the Weitek FPU to their code therefore resulting (hopefully) in a large performance increase by using simultaneously the CPU Integer math, FPU floating point math and the Weitek FPU math! This should if possible result in being able to run Quake properly on much lower specked 486 systems as long as they are the DX model plus the Weitek! PLEASE PLEASE TRY!!!!

[@intotron6708]

Thank you very much for this interesting Retro video, I enjoy those very much. About your question on intel and the 486/487SX series, I always imagined intel used this as an opportunity to sell a CPU which failed the quality test in production. The 486SX failed on numeric coprocessor function at least, and the 487SX simply failed the speed tests. The chips were packaged different (pinout) to sell them with different mainboards. But I personally at least once saw an 487SX on an adapter board to place it in a regular socket for 486DX. The same reasoning was with the special DRAM module. A partially defective DRAM chip was bonded directly to the PCB, so it could be used with lower capacity still.

[@jilmarit]

Wow! I would find lot more use for that computer in 16MHz configuration. Older 80’s to 90’s games problems with high speeds would run great with 386/33MHz or comparable - for example adventure games, Wing Commander series, etc. Having already i486dx4 and 5x86P75 leaves a spot at that range underneath. Also my 286 is breaking and a little slow anyways to restore.

[@jrherita]

I'm really curious how high that 486SX-16 would clock. I'm fairly certain it would do at least 33 MHz, and probably 40-50 MHz. I had an old 486DX-25 that ultimately ended up at 48 MHz, though it wouldn't work at 50 MHz. (In hindsight, it was on a "33 MHz rated board", so it could have been the motherboard not the CPU limiting performance). This was around 1993 or so.. My BBS + gaming + work setup consisted of several 486's...

[@seeigecannon]

Something I just realized with the older motherboards is they don't use serpentine/matched traces. I guess it makes sense with the slow clock speeds, but it is weird seeing motherboards without them. I do remember my 333MHz computer had them, so the cutoff must be somewhere below that. Great content as always.

[@joefish6091]

unequal trace routing is problimatic with high speed busses, latency timing becomes critical.

[@seeigecannon]

@@joefish6091 yeah. I design PCBs, but mostly as a hobby. The only length matching I have ever needed to do was for USB. It is fun watching videos on DDR3/4/5 though and realizing how slow the speed of light is to require length matching.

You just created ISA perfection.

I remember upgrading from my original dx2-66 to the AMD K5 and being blown away. It was like having a new PC for around £70.

[@dr_jaymz]

That works a lot better than I thought it would. I wonder how affordable that would have been at the time? I'm not sure of the exact timing but I imagine at that point many would be using early pentiums and the cost of upgrading was plummeting which if I remember made these types of upgrades disproportionately expensive. But, it does work very well.

Another interesting adventure in retro. Did you notice the strange looking "L" in the BIOS info and menus? Why do you think it is?

[@johncate9541]

I bought one of those Kingston upgrades in the late 1990s to upgrade a Dell tower with an SX-33. It was like night and day, even compared to an SX twice as fast as yours. I ran that machine into the early 2000s before the motherboard failed.

Good times! I had a Cyrix 133 back in the day.

In the age of 486 the Weitek FPUs usually weren't faster anymore but they were often required for expensive software because they used incompatible Opcodes. Think of them as dongles which actually do something useful.

That´s a beautiful and true retro DOS PC

too bad you stopped making videos, I like your straightforward style. Plus who else makes a stop motion animation of chips going to and from a socket! =)

[@CPUGalaxy]

I hope to go on soon with production. I collected parts over the last year to cover at least 100 videos. Thanks for watching my channel. cheers, Peter

I was expecting it to run even faster after the installation of the Kingston Turbochip. I run it on a microchannel IBM PS2 77s with an onboard S3 of 1MB and Doom runs extremely smooth. 3D Bench reports a score of 76 frames per second.

By the way, from my own experience the cache being configured as Write Back instead of Through is faster usually.

Hehe, the nostalgia of the games I used to play back in my teen years :D

Hahahaha - "And to scare the sh&^ out of this motherboard" - laughed for 5 minutes!

The lack of any improvements with tweaking is indeed a side effect of the SX 16 being such a bad chip, it was basically a 386sx with some 486 instructions glued on the base architecture is still 386 though so it gets zero advantages from anything the faster full fat 486 chips could take advantage of. The bios doesn't "detect" the CPU per se on most mainboards from 8086 up until Pentium mmx chips , these were configured via jumpers or dip switches on the board whatever those toggles told the bios it put next to the vendor id from the chip and displayed that. Setting the jumpers to use the 50mhz FSB should also improve performance noticeably over the 16mhz setting. Also quadrupled is roughly pronounced Kwa-Droop-Ld btw.

Oh, these memories, I remember, that one friend had similar board with 25Mhz 486SX, and after his brother borrowed him 16MB, he was playing with Adobe Photoshop 2.5 on Windows 3.1. I would be curious, if that 16Mhz version can handle 25Mhz, or 33Mhz, personally till today I even didn't know that 16Mhz version of 486 exist, it must be extremely bad batch, so they clocked it such as slow. Anyway isn't it Write back faster option, then write thought? I know that write thought has been more prefered in servers, as it was safer.
