Back in 2001 I've bought a dual CPU system (MSI 694D Pro Dual Socket-370 Apollo Pro133A ATX, 2* Pentium III 800MHz), which was an absolute beast at the time. I was running Multiple Game Servers at a LAN-Event, listening to Winamp while gaming Counter Strike at perfect framerates. PC just didn't want to slow down a bit.

[@zyme5998]

Wow, How did I possibly not know about this motherboard, back then I used MSI almost exclusively *Except* for my ABit BP6 (Dual 370 system using 500mhz Celerons) and slightly later an ABit VP6 using two 1ghz Pentium III's. The speed was insane, as long as you used Windows 2000 as 98/ME [BSD also, but not Linux] didn't support SMP. I'm pretty positive most the speed gain was from most software only capable of using one CPU at a time, occasional software lockups that would become transparent, and similarly not having to distribute the cpu's resources across twice as many processes/threads/whatever. The machines truly seemed 10x or faster in many cases.

The main benefit of two CPUs is the increased RAM that you can install, as well as potentially more PCIe lanes depending on the chipset.

[@shadowslayer7600]

What would be cool with 2 CPUs is to be able to choose what CPU a program uses I.e run a game that can't use many cores on your better low core CPU and have a high core count CPU for work that can use lots of cores

[@GeorgePerakis]

Simple answer: The Windows scheduler can only barely handle existing single socket Threadripper platforms as it is.

[@another3997]

Not a good answer... there are other operating systems out there that have run on multiple CPUs for decades. Windows ran fine on multi CPU machines, but only if software was written well enough to take advantage.

[@setcheck67]

The real simple answer is that programs often share memory space and memory can only be written to by one core/CPU at a time. This is why hyperthreading programs is *really* hard as the split process *cannot* write to memory used by the main loop of the program. So generally hyperthreading is programmed as single purpose tasks that perform one thing and then nothing else.

@@fastestmane7324 Here's the song: kzbin.info/www/bejne/j5_SoXt5gZZ9oZo It's also called the "numa numa song" because of the chorus. NUMA in computing stands for Non-Uniform Memory Access. Due to the nature of multiple CPU architectures, typically each CPU has its own memory bank, and there is a substantially latency hit when accessing memory locations that are physially located on the other CPU's memory bank (typically accessed via some bus or crossbar).

[@kcnq2245]

I think that might be the most obscure reference I have ever seen

[@AndrewTSq]

Many arcadeboards used dual cpus and that scaled really well on Segas arcade for example (no pun intended since they were the masters of 2d scaling sprites). sega genesis used 2 cpus, where one of the cpus was in charge of the music.. the ps2 used a ps1 cpu also for handling io and backwards compability.. list goes on. if you dont make software to take advantage of extra cpus, you will not see great benefit.

[@lukas_ls]

There is a benefit in having dedicated sockets for your CPUs: Especially Threadripper suffers from its design. They put 8 dies on one package that then has to share all its memory bandwidth. In a multiple socket build each CPU gets their own dedicated memory and bandwidth. In a threadripper 3990X 16 cores share one memory channel. If you had two 32 core systems or 4 16 core systems with 4 channels each you could get way more performance in tasks that don't require shared memory like virtualisation.

[@NextMerckx]

And this goes back to at least Westmere. Back in the day, one of the awesome things that the Dell Precision T5500 had in it was the second CPU riser functionally made the system parallel triple channel memory, so you could get some absolutely absurd memory bandwidth for the time (like ~60GB/s theoretical or something) to pair with the then-ludicrously-powerful X5680 and X5690.

[@DozIT]

@@NextMerckx Yep, lol I still like to think the X5690 is ludicrously powerful even at $200 for a pair. My Mac Pro 5,1 and R610 Server does more than keep up.. even a decade later!

[@StCreed]

This is why a database server we bought around 2015 was equipped with two 12/24 Xeons. For database servers, memory bandwidth is a real bottleneck (we saturated two fiber channel links when running queries to give an idea of the amount of data we were sorting, and we had nearly 1TB in memory)

[@tezinho81]

My first dual processor machine was a pentium pro, this goes wayyyyyyy back as the man says.

The diminishing returns is a much greater problem for Windows compared to other O/S such as Solaris.

Solaris scaled far better than Windows when it came to multiple threads. Floating point performance wasn't as good. But moving large amounts of data, processing big datasets etc was short work for SPARC based machines. Today, Sun/Oracle do the same work with connected servers running XEON processors. Provides some cost savings as well as multiple systems running so the loss of any one system has a far smaller impact compared to one large instance going down. 1U servers running Oracle Enterprise Linux with 1.5TB of RAM to do database "stuff."

The good thing about multi-CPU systems is that they were pretty much future-proof. I'm still using an OC dual-Xeon system (two 6-core CPUs at 4.33GHz) on EVGA SR-2 (MB and CPUs are from 2010) together with a 1080 GTX, and it holds up great at 1440p. This configuration saved me at least one generation of upgrades, so investing in it back then might have been a really good choice. I wouldn't go for it today though.

1:05 -- I guess I don't recall how long after launch I upgraded -- but when I went from my 386SX-20 to a 486DX-33, the whole upgrade (including going from 2MB to 8MB of RAM), was around $800. Now this did include trading-in the old CPU and RAM, not that I think it was all that valuable at that point, but lets call the without trade-in price was ~$1000 The RAM was $54/mb (not sure why I remember that so specifically), so that was $432 of the cost, which leaves ~$570 for the CPU upgrade and labor. IIRC, a motherboard swap was not required, but I could be mistaken. If so, some of that $570 would have gone to the motherboard as well.

What prevents having stuff like multiple graphics cards and multiple cpus common place in the pc industry is that the amount of heat that you will be producing is quite bad and unless you've got expensive/risky water cooling your pc will just melt

[@clicktobhushan1]

basically we can increase the bus width on motherboard and divide it equally to multiple cpus by creating data dividing bridge on motherboard for processing. In this way by using two 64 bit cpus 128 bit data can be processed at a time, 256 bit data by four 64 bit cpus, 512 bit data by eight 64 bit cpus and so on for next generation ultra fast processing technique.

[@daringcuteseal]

[@JoeStuffzAlt]

That kind-of happens with Windows now. Windows may try to stack as many small programs onto a single core when the cores are not loaded to take advantage of turbo boost. It's very hard to use exactly 100% of a CPU. With just a 2nd core, you almost always will have at least a tiny bit of CPU power to keep things running more skookum. I think the PS4 also did what you mentioned. There's a mini OS on an ARM processor or something to help run stuff in the background. It led to some weird things like a hard drive running off a USB bus. Seriously... check out the PS4 hack video.

You can get 8 cpu and 4 cpu systems for reasonable prices, the reason you would get one: any cpu thread heavy application such as physics/stats calculations,/3d rendering.

EVERYONE but Intel calls it Simultaneous Multi-threading because that's the actual term for it. "Hyperthreading" is just a marketing term that Intel made up.

"SMP" covers more than one CPU. So like dual celerons, dual core chips, two quad core chips, etc. Hyperthreading is a more specific thing. "SMT" (What wikipedia says Hyperthreading is) is different from "SMP"

[@kevintrumbull5620]

Once again, SMT is the proper industry standard term for having multiple pipelines for processor cores supporting more than a single thread of execution simultaneously on each core. "Hyperthreading" is Intel's marketing term for their implementation of SMT. en.wikipedia.org/wiki/Simultaneous_multithreading Interestingly enough, Intel's "Hyperthreading" is one of the least "Hyper" threading implementations out there. Sun's Niagra processors supported 4-way SMT many years ago. IBM's POWER 9 CPUs support 8-way SMT. Obviously SMT is not the same as SMP. I did not state anything about SMP.

I had a dual Pentium 166 back in the day. It wasn't just that there wasn't much in multithreaded programs. You needed at least Windows NT or Linux to even be able to use the second cpu. In W95 or W98 the second CPU was unavailable... Also in those days the CPUs had to be the same and preferably from the same batch or it would be unstable. But it did allow you to encode a CD to MP3 and still have usable system. Which mattered since encoding an entire CD to mp3 took hours that you could otherwise not use your system for something else ;-)

[@DakalaShade]

For a time, I ran a dual-CPU rig (EVGA SR-2, dual E5645, 12GB DDR3), and while I loved it, I won't go back to multi-CPU unless I have to. The major reason is this: When something goes wrong, you have (nearly) twice as many components to check over to find out what caused it. Whether it's reseating 6 sticks of RAM in a futile hope to find that missing 2GB, replacing both CPU coolers because one AIO liquid cooler has decided to stop cooling, or irritating software compatibility issues caused by having too many cores for your older software to comprehend, you're going to have problems. Add to that the general size of any multi-CPU build (the boards are massive, requiring massive cases, which then require huge amounts of room to put them), the power consumption (When just idling can consume enough power to run a normal CPU flat out, it's bad), and the added maintenance headaches (cleaning out your heatsinks? Here, have twice as many. Dead CPU fan? Replace both, because if one died, the other's not going to last much longer. Time to reapply new thermal compound? Have fun, you get to do it twice), and you end up with a mildly frustrating experience. Don't get me wrong, if you're up for a high-maintenance machine that, 90% of the time is rock-solid, Dual-CPU is great. That machine will likely remain as my fastest ever computer, and the longest I've ever run a single board without significant upgrades, but I found out it's just not for me. And there's nothing wrong with that. It's like trying liquid cooling, deciding it's not for you, and going back to air cooling with big tower heatsinks. I did that, too, because air cooling is simpler, less likely to break down, blow up, or just flat out make a mess. The biggest things that have actually made this decision for me is upgrades and performance. See, in a normal single-CPU system, you have three major upgrades that don't really have to cost too much. CPU, RAM, and GPU. I'm ignoring hard-disks or SSD's, they don't count for this purpose. In a dual-CPU system, you have twice the amount of CPU's to upgrade at the same time, and twice the amount of RAM that has to be upgraded, again, at the same time. Suddenly, any CPU upgrade you're looking at is instantly twice as expensive. Hence, I kept E5645's the whole time, because anything faster would need two chips, and that gets pricy fast. I had 6 sticks of 2GB Corsair Dominator memory, because dual-CPU-triple-channel required that as a minimum. Any upgrade to my memory would have been a full kit of 6 sticks, minimum. And that performance half of it? I'm not just talking programs here. In that system, there would have been no benefit to the boot time by installing a solid-state drive. What's 15 seconds going to save me when it takes 30 seconds to check out everything before initializing the display? Then there's programs that don't recognize CPU1 and so they all pile up on CPU0, there's programs that crash because somehow CPU0 is handling all of their workload, but CPU1 is where the program's memory got allocated, and there's the fact that 80% of your average daily workload, as a home user, is unlikely to make the most of even one of those 6-core-12-thread Xeons. So, while I loved it, it sits there under my desk while I use a laptop with an i5 that I swear feels faster some days. Partly, the desktop is out of operation because of an overheating issue that I can't solve. Considering the board's northbridge cooling fan exploded, I'm not that surprised, and considering the number of changes I've made over the roughly 9 years of ownership, I wouldn't be surprised if I blocked the airflow to something like the VRM's and never noticed it, but I tried for three months and still couldn't keep it stable in the summer. As for what my next main rig will be, I don't know yet. Ryzen has me tempted, though. For now, my trusty i5-5300U and my 8GB of RAM is good enough.
