Gaming Tests: World of Tanks
Albeit different to most of the other commonly played MMO or massively multiplayer online games, World of Tanks is set in the mid-20th century and allows players to take control of a range of military based armored vehicles. World of Tanks (WoT) is developed and published by Wargaming who are based in Belarus, with the game’s soundtrack being primarily composed by Belarusian composer Sergey Khmelevsky. The game offers multiple entry points including a free-to-play element as well as allowing players to pay a fee to open up more features. One of the most interesting things about this tank based MMO is that it achieved esports status when it debuted at the World Cyber Games back in 2012.
World of Tanks enCore is a demo application for its new graphics engine penned by the Wargaming development team. Over time the new core engine has been implemented into the full game upgrading the games visuals with key elements such as improved water, flora, shadows, lighting as well as other objects such as buildings. The World of Tanks enCore demo app not only offers up insight into the impending game engine changes, but allows users to check system performance to see if the new engine runs optimally on their system. There is technically a Ray Tracing version of the enCore benchmark now available, however because it can’t be deployed standalone without the installer, we decided against using it. If that gets fixed, then we can look into it.
The benchmark tool comes with a number of presets:
- 768p Minimum, 1080p Standard, 1080p Max, 4K Max (not a preset)
The odd one out is the 4K Max preset, because the benchmark doesn’t automatically have a 4K option – to get this we edit the acceptable resolutions ini file, and then we can select 4K. The benchmark outputs its own results file, with frame times, making it very easy to parse the data needed for average and percentiles.

WoT is a fun test to see 700 FPS+ numbers with the best CPUs. However the differences between the CPUs end up being minor.
All of our benchmark results can also be found in our benchmark engine, Bench.

and you are a Computer Science graduate? What Linus T. is saying is that AVX-512 is a power hog and he is right about that. Linus T. is not saying that "a couple dozen or so people" are able to program it. Power requirements and programing hardness are 2 different things.On the second point, I 100% stand by that any decent Computer Science/Engineering graduate should be able to program AVX-512 effectively (overcoming hardness not power requirements).
Also, I do program AVX-512 and I 100% stand by what I said. You just need to know what you are doing and vectorize algorithms. If you use the good old sequential algorithms you will not archive anything with AVX-512, but it you vectorize you're classical algorithms you will also achieve >100% benefits in many inner loops in so called mainstream programming. AVX-512 can give you 2x uplift if you know how to utilize both FMA units on port 0+1 and 5 and it's not hard.
Lastly, with decent negative AVX-512 offsets in BIOS, you can bring down the power utilization to ok levels AND still get 2x improvements in the inner loops (because of vectorized algorithmic improvement).

> and you are a Computer Science graduate?No, I am a Computer Engineering graduate. Sorry, but you are grasping at straws. Plus you are overcomplicating the obvious to try to be an Intel apologist. Just see this and this. Read it and weep. Intel flopped big time this release:

So fellow CS/CE grad. I'm not arguing that AVX-512 is a power hog (it is) or that the AVX-512 offsets slows down the rest of the CPU (they do). I am arguing the premise that AVX-512 is supposed to be so incredibly hard to do that only "couple dozen or so people" can do is wrong today - Skylake-X with AVX-512 was launched 2017 for heaven's sake. Surely, I can't be the only CS/CE guy how figured it out by now. I mean really? When Ian wrote what Keller said (and keep on writing it) that that this AVX-512 is sooo hard to do that only a few guys on the planet can do it well, my reaction was "let's see about that". I mean come on guys, really!SystemsBuilder - Wednesday, March 31, 2021 - link
More specifically Linus is concerned that because you need to use negative offsets to keep the power utilization down when engaging AVX-512 it slows down everything else going on. i.e. AVX-512 power requirements overall CPU impact. The new cores designs (already Cypress Cove maybe? but Sapphire Rapids definitely!) will allow AVX-512 workloads to run at one frequency (with lower negative offsets that for instance Skylake-X) and non AVX-512 workloads at a different frequency on various cores and keep within the power budget. this is ideal.arashi - Wednesday, March 31, 2021 - link
This belongs in r/ConfidentlyIncorrect and r/IAmVerySmart, anyone who thinks coding for AVX512 PROPERLY is doable by "any CS/CE major graduate worth their salt" would be laughed out of the industry.Hifihedgehog - Wednesday, March 31, 2021 - link
Exactly. The real reason for the nonsensical wall of text is SystemsBuilder is trying desperately to overexplain things to put lipstick on a pig. And he repeats himself too like I am listening to an automated bot caught in a recursive loop which is quite funny actually.SystemsBuilder - Wednesday, March 31, 2021 - link
So you are a CE major, have you actually tried to program in AVX 512? If not, try to do a matrix by matrix multiplication of 16x16 FP32 matrices for instance and come back. You'll notice incredible performed increase. It's not lipstick on a pig, it actually is very powerful, especially computing through large volumes of related data SIMD style.Meteor2 - Saturday, April 17, 2021 - link
Disappointing response. You throw insults but not rebuttals.Me thinks SB has a point.

really? any you are one CS graduate? have you tried?MS - Tuesday, March 30, 2021 - link
What the he'll is that supposed to mean that you can't you can't get the frequency at 10 nm and therefore you have to stick with the 14 nm node? That's pure nonsense, AND is at 7 nm and they are getting the target frequencies. Maybe stop spreading the Coolaid and call a spade a spade....
