[@TheMasonX23]

As a game developer (specifically a programmer), I'll definitely confirm that designing an algorithm or workload to efficiently take advantage of parallel processing is far more difficult than traditional serial processing. In addition to designing around parts being split up into separately processable chunks, there's also a lot more technical hurdles when actually implementing it like making things thread safe, preventing race conditions (so the order they finish doesn't potentially break things). It's awesome in theory, and great when you can do it, but it's a lot harder in reality, especially with current setups that are often ill-equipped to deal with this.

[@IceQub3]

i blame openGL

[@friendstype25]

I went to a class about writing programs to take advantage of parallelization. I came away with a whole new respect for those who do. There are a lot of hurdles even when a process can run on multiple threads at a time. Things you might just take for granted.

[@FustFPV]

Glad you added in programmer. To many times have I spoken to game artists who says they are a programmer then when you start talking to them about even the basics about programming they say "oh no i just make designs for games like the charictor models, someone else writes the code".....

[@jonathanng138]

Hi its almost 2020 how's this going so far now?

[@HVDynamo]

@CS:GO сФинщини It's Race condition, not trace condition. But ultimately two pieces of code that are running in parallel are racing to complete, if your code requires them to finish in a specific order to process correctly, this must be handled so you don't end up with the other piece of code winning the race and resulting in an incorrect output of the total function. It can get pretty complicated, but that's just the basic idea.

[@5dstrix]

Honestly linus, I already know 99% of what you go over in these videos, but I still watch them whenever they show up in my "recommended videos" section, half because sometimes they're the best way to share a link and explain something complicated to a friend, and half because I just enjoy your explanations for unexplainable reasons (mostly, I'm a dork)... keep it up man, much respect, love the empire you've been building and I'm looking forward to seeing how far you can take it!

[@5dstrix]

Also... as a game programmer working in a decade+ old proprietary game engine, who has to use threads for basic tasks like calls to an SQL database, I can definitely say you're on point with even NON-commercial game engines not being optimized for multiple threads yet... our Technical director is looking into heavy compute workloads right now, but we just CAN'T rewrite the entire engine to take advantage of all these fancy schmancy cores/threads that we have available to us now. This is why doom had me in absolute AWE... it's the first game I've been able to play as a professional game programmer that made me say "HOLY FUCK, THAT'S WHERE WE NEED TO BE GOING!"... it's also getting sli/crossfire support soon (if it hasn't already, I upgraded from 570s in sli to a single 770 a while ago, so I wouldn't know unless I happen to read/hear about it)... but that's HUGE... deferred rendering is killing a concept that's been baked into the DNA of PC gaming since the days where the word "Voodoo" had nerds creaming their pants, I understand from an engineering standpoint why deferred rendering is appealing... you can do MORE with a single card, but throwing away the modding community (which I'd argue is one of the coolest communities that PC gaming has created) is a step backwards, not forwards... We're going to be getting explicit multi-gpu, which should address a lot of this... but honestly, look at what ID just did (digression comeback, w3w+), and it's apparent that a deferred rendering pipe isn't necessary to get MASSIVE amounts of work done and still have your game run well on lower-than-should-be-possible spec'ed machines. sorry... got into a rant there, I'm sure the 3 people who read it might appreciate some of it :P

I'd like to expand a bit on what Simon said. Not that any of it was wrong, but your initial assumption wasn't exactly wrong either. If a specific game that was not written to take advantage of multiple cores could run at 60 fps (where CPU usage is the limiting factor) on a CPU with 2 cores, then if you tried to run the same game on an identical CPU with only one core, it would not be able to achieve the same performance. And this is because the 2-core CPU has extra capacity to run other tasks.

[@jessicadayla]

Disagreed in the year of the Phenom II x6. Use software to move ALL background, office, and communications processing (low computational load) to 2 cores, use the other 4 for computationally heavy stuff. Its a necessary thing when you do computationally heavy work, and if something can utilize more than one core, moving other things off the cores its using gives it more room to work.

And do you have a 64 core computer? Just because the parts are available doesn't mean that people are buying and investing in them. And game engines still only typically use 1 to 4 threads maximum, so per core speed is still better than more cores for gamers, and a quad core is usually enough, even in 2019.

How do Rar and Zip Archives compress files?

[@0M9H4X_Neckbeard]

there's already a techquickie on compression

[@brcha]

Lookup Huffman coding. That's the most basic starter compression algorithm. Default zip compression algorithm is basically huffman code, but more advanced compression algorithms, both in zip (and gzip, bzip2, lzma, 7zip, ...) and in rar are specifically tailored for certain file types and would be complicated to explain. Huffman, on the other hand, is quite simple. It sorts bytes by frequency of occurrence, puts it into a balanced tree and then encodes them in the shortest possible strings of bits. So, the most occurring byte will be transformed into, for example 3 bits, while the one occurring rarely will be transformed into 15 bits or something like that.

[@fordfiveohh]

basically you need a thread to use more cores... period. but yes, a thread is sort of a workload delegate . Then all these threads have to re sync or callback once complete to glue the whole back together from the parts.. also some things can't continue serially until that multi threaded event has completed ... so you need a thread join etc. With things like that , you sort of get processing bursts that are fast versus constant fast processing. You still have scheduling overhead though, so if it's a short task, it's probably not worth delegating to threads. You have things that would be like telling 5 people to go get your mail . sure, each may grab an envelope but since it's a simple task, it doesn't matter. Instead, if you tell 5 people to start unloading Sod from a truck , maybe that's worth it as they will obviously be faster than one because it's splittable HEAVY work and obviously the scheduling overhead isn't a concern (the time taken telling who to do what ). but most people haven't done multi threaded programming so your explanation is fine. For those who want the nitty gritty , Google about what I'm saying.

[@Sinom.]

I had a similar CPU too and it works but there are Intel CPUs with 4 cores that are faster that it (even some 3rd gen ones)

[@MasticinaAkicta]

Well, how good is the cooling and how fast is the processor running. Per Core performance is lower then Intel, so to reach the same level you have to overclock. And to do that you better have a good PSU and good Motherboard that can handle it. Not Overclocked the fx 8350 will be less powerful then many core i5's. In some tasks even less powerful then a core i3. But in other highly parralel tasks it might be faster then a core i5. In short, it depends on the task/game. See it this way, if the fx 8350 bottlenecks your new GPU just think of the performance you get once you buy a new motherboard/cpu/memory with a better architecture. And yes AMD is coming out with their Zen cpu. That should be interesting for AMD users. There are no benchmarks out yet but it will be an 8 core that functions as an 16 core. If the Per Core Performance is good it should be a great processor.

[@freddiewm1502]

***** It shouldn't slow it down as GPU bottle necking takes a really slow CPU. And is very rare. The FX8350 will not slow the 1070 down. But he would be better off getting two RX 480s in cross fire when they come out.

[@helenewels2878]

The up side to having an 6,8 or 10 core cpu is ..you can disable them in task manager if they dont benefit in a specific game so gain more fps..but game and download or stream at the same time and a multicore cpu is an absolute winner.

[@scottfranco1962]

Most of what multiple cores are used for today is polling. The "non-blocking" interfaces used in Windows and other operating systems encourage polling, or repetitive checking for results from say, an internet channel. Thus you get an apparent boost just from giving programs their own core to waste. Parallel programming is difficult. Few programmers understand it, much less implement it.

Main reason is heat. Somewhere along 10ghz single circuit is fried by heat while multiple cores in lower clock speed do the job

[@zacksstuff]

I just installed a new Z97 motherboard in my computer and I was messing around with overclocking. While I couldn't get my i5 4670k stable at 4.2 GHz on all four cores, I was able to set up dynamic multiplier based on how many cores are under load (the same method is used for Intel Turbo Boost). If a program is only hitting 1 or 2 cores, my CPU will clock up to 4.2 GHz. If it hits 3 cores, it tops out at 4.1 GHz, and a 4 core load will top out at 4 GHz, the frequency I was using with my old motherboard. In theory, this will allow single-threaded applications some extra power, without my computer locking up from a sustained multi-threaded operation.

Zen 2 beats Intel in almost all single threaded applications even at lower clocks and zen 3 will wipe the floor with Intel for at least a year.

[@ZZstaff]

It is easy to code for one core, more difficult for two, and from there the bell curve rises very quickly, especially for programs like gaming - because there are so many different ones and different companies. For some dedicated programs it is not so difficult. That is why having a 4 core is sufficient for gaming, sometimes a fast 4 core, and sometimes this brings us to overclocking for more FPS.

[@RadioactiveBlueberry]

Well, from sales perspective I think, most games don't necessarily even need to be optimized for higher core count than exists today or near future. Balling around more threads than the CPU is capable of handling, is a performance loss overhead. However, number of threads doing a similar job can be easily adjusted automatically, which usually scales pretty well between different hardware configurations if done correctly. As of 2021, I recently bought my first game which doesn't run well on my 4c/8t CPU anymore, FPS often falling below 30 while CPU is working around 85%. That said, it's probably safe to assume that gaming sweetspot is currently at 8 cores, some already taking advantage of 16 threads. Single core performance just can't improve forever.

[@ZZstaff]

@@RadioactiveBlueberry This thread is over 5 years old, however with that said what CPU do you have and what game gives it problems?

[@RadioactiveBlueberry]

@@ZZstaff I have i7-6700K paired with GXT 970 and the game in question is Horizon Zero Dawn, although I first tried it using stereoscopic 3D which this game renders perfectly (in most games it's usually half-broken or nonexistent), hence half the framerate but still below 60 FPS even under normal conditions @720p resolution. Benchmark reports look like GPU could be able to pull more frames than it did, indicating CPU as a bottleneck, although GPU in overall was working harder when I now checked it again. Regardless the game clearly uses actively more than 4 CPU threads.

[@ZZstaff]

@@RadioactiveBlueberry For some reason I was thinking you had an Intel 6600K, sorry.

You can see the settings they are using. By the way how much system memory do you have, 8GB or 16GB or more? At 16 seconds into the first video he is using 12GB of system memory and the second video [GTX 980] he is using over 8GB of RAM [system memory].

[@burakcz2035]

can somebody explain to me what is overclocking ?

[@victors8718]

Just do a quick search on YT. You will find lots of videis about that

[@xygomorphic44]

Your CPU has a "clock" which is just a thingy inside that turns certain wires on and off in sequence really fast. These wires go to different parts of the CPU, keeping the whole CPU going. A "clock cycle" is when the clock goes through all it's wires once and then starts over again. The "hertz" is how many clock cycles the CPU can go through per second. So a 1GhZ CPU can do a billion clock cycles every second. "Overclocking" is when you make the clock go just a wee bit faster, so that each component in the CPU cycles quicker. This lets the CPU process instructions faster and speeds up the computer. But there's a tradeoff, you can only overclock a little bit, maybe 10-20% if you're lucky because the CPU isn't designed to work that way. So you can't do crazy things like "double your speed". It's also more likely to introduce errors. That's why overclocking is the "poor mans way" of getting a better computer.

@@shadowxxe Yeah that might be true, but I was talking about video games specifically. And that struggle you said is probably due to the fact that they are 1st gen and has nothing to do with them being quad core. The thing is, utilizing multiple cores for video games is a theoretical/algorithmic issue rather than anything to do with hardware. So even today you could have a pc with 60 cores for all I care, the performance is gonna be the same as a quadcore cpu (for videogames).

[@HVDynamo]

@@user-dXNlcm5hbWU I think six cores is becoming the norm for a good performing gaming PC though. A lot of games are starting to use 4 or more cores now, and if you want to have any background tasks running a couple extra cores is nice.
