Gaming Tests: Strange Brigade
Strange Brigade is based in 1903’s Egypt, and follows a story which is very similar to that of the Mummy film franchise. This particular third-person shooter is developed by Rebellion Developments which is more widely known for games such as the Sniper Elite and Alien vs Predator series. The game follows the hunt for Seteki the Witch Queen, who has arose once again and the only ‘troop’ who can ultimately stop her. Gameplay is cooperative centric with a wide variety of different levels and many puzzles which need solving by the British colonial Secret Service agents sent to put an end to her reign of barbaric and brutality.
The game supports both the DirectX 12 and Vulkan APIs and houses its own built-in benchmark as an on-rails experience through the game. For quality, the game offers various options up for customization including textures, anti-aliasing, reflections, draw distance and even allows users to enable or disable motion blur, ambient occlusion and tessellation among others. Strange Brigade supports Vulkan and DX12, and so we test on both.
- 720p Low, 1440p Low, 4K Low, 1080p Ultra
The automation for Strange Brigade is one of the easiest in our suite – the settings and quality can be changed by pre-prepared .ini files, and the benchmark is called via the command line. The output includes all the frame time data.

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....
