They're also what kills Intel's CPUs when they try to use them, as the units produce a lot of heat to do a calculation. AMD's current response is "just use a GPU, you moron", because that's what GPUs do. They're used in very little at the moment because Intel only just launched any normal consumer parts with AVX512 units (Icelake Mobile). 

So it's pretty much useless for us as consumers?

AVX and AVX2 get used heavily already, but AVX512 will be of limited utility for a long while. Really need DDR5 out before it makes too much sense. And small nodes for power usage.

Don't mind if I wait a week to find out whats actually happening before I get my nickers bunched up.  Like nearly every other issue with bench marking and reviews that seem to unfairly favor one company, this will likely turn out to either be simply misunderstood by everyone or an accident that gets fixed.

QuicK and DirtY. Read the CoC it's like a guide on how not to be moron.  Also I don't have an issue with the VS series.

Sometimes I miss contractions like n't on the end of words like wouldn't, couldn't and shouldn't.    Please don't be a dick,  make allowances when reading my posts.

Negative. Most software uses AVX instructions if cpu is available to process it. 

DX12 games are using AVX and AVX2 instruction sets.

You can stress test with Prime95 and OCCT that utilize AVX. Good for heat build up!!

Cinebench uses AVX instructions for example. That's one of the reasons the cpu gets so hot.

Now compare a Cinebench load to a WPrime 1024m load, you'll see a big difference while Wprime does not use AVX instructions for the calculation.

- If it ain't broken, don't fix it! -

- Your post codes and beep codes in the drop down below.

More importantly to normal consumers... yes AVX is power hungry. It's also flipping fast compared to the instructions it's replacing, and can sometimes mean a 4x+ speed increase in that part of the code.

 

So it is 100% worth the heat to use, not just people playing with their toys.

According to Intel Passmark is 100% representative of real work cases; unlike Cinebench and others.

Note this is only instruction support, and tells you nothing about hardware support. For example, Zen 1 architecture has about half the throughput of Zen 2 yet both support AVX2. AVX-512 is also complicated in that Intel offer one unit and two unit implementations. The two unit ones offer potentially double the throughput of one unit ones. One unit ones seem no better than AVX2 in throughput. Having said that, AVX-512 is a family of instructions, so in other use cases even a single unit implementation may provide performance improvements in other areas.

The problem is AMD (and nvidia) killed FP64 performance on consumer models, with the VII being the only recent exception to the rule. Also GPUs still remain "dumb" enough not to be able to cope with more complex workloads a CPU can. GPUs wont replace CPUs in all scenarios even if they have a lot of potential performance.

The problem isn't a benchmark is synthetic or not, even "real" task benchmarks will have problems. The problem is that everyone values different things different amounts. There is no good way to get a complex measure down to a single number that can be compared.

In theory at least, anything capable of using older AVX can be scaled up to get AVX-512 performance. The bigger limit to software adoption I feel is simply that there aren't enough AVX-512 capable CPUs in the wild yet.

We have to state version also. I'm a bit rusty on this, I think Cinebench R15 did not use AVX, but R20 does.

As noted in my previous post, keep in mind that the scores presented appear to be based on user submissions of each CPU. A less common CPU's score could be skewed by a user who might overclock hard.

 

Hmm... if I have time I could try and separate out the Intel K skus from nearest non-OC ones and see if they punch above their weight from that. As most AMD CPUs can be overclocked there's no practical way to do it for them.

@porina @Lurick here's the Passmark dev discussing the changes and the effects. Notebookcheck is clickbaiting a bit. It really seems V9 was actually sandbagging Zen2 a bit and the V10 now makes the single-core test very sensitive to Clocks. (And it slams a bunch of the Intel Mobile parts.)

I was skimming that thread already. The way I read it, there seems to be a lot of noise from those who might be over-invested in this scoring metric.

Given that Zen2 and Skylake have generally similar IPC (on net, per-tasks there's up to 25% differences; see The Stitl's in-depth testing), this actually isn't too surprising. But Passmark should probably clarify what the point of their test. Not that pure single-core really matters for anything.

I'm having some fun on another forum, and might have to buy a higher core count Zen 2 to investigate it. In Prime95 like workloads, I had previously determined the peak performance of Zen 2 architecture was greater than Skylake. But now I've seen multiple reports including the 3950X and the threadrippers above that, that performance on them might only be half that expected. Back down to Zen 1 levels. Ouch. Clocks are in expected range, with no thermal, power or current limiting. Prime95 bench itself doesn't show anything unusual, so I'm suspecting it is the other software (which uses the same compute code as Prime95) acting differently.

 

As a side effect of that testing, I did note my 3700X, currently running at 4.1 GHz, running two 4-core tasks, is doing individual tasks slower than a 6700k at 4.0 GHz. Of course, the 3700X still has near double the throughput from the extra cores, but in theory it should not be slower per 4-core task. These tasks are in theory small enough that ram bandwidth shouldn't be a limiting factor. This is something I could look into also.

While Cinebench R20 has been out for a while now, I feel that R15 still has a lot of momentum behind it so I wanted to be clear.

So what was the purpose behind this passmark update? I heard that the devs said that v9 was sandbagging some Zen2 CPUs but it seems that the update to v10 simply sandbagged them more. Was there any useful reason that they updated the benchmark?

So you do that for every company then?  Every time something doesn't look right to you you accuse a company of anti consumer behavior?   If not then remember that this is no different, wait until you know why the score is the way it is before outright claiming Intel paid for it.

when stuff doesnt look right (and it actually isnt right in this case btw), the dev doubles down on it knowing that, and it benefits third party that was proven to do similar stuff before. ye id do that for any other company like that

Again, do you apply that rule to ALL companies when something doesn't look right?  Or does the rule only apply to Intel?   So often people make absolute statements (as you have) with no regard for critical thinking or the impact it might have to the general internet ignorance that reads it.

So basically AMD and Intel share similar IPC but because Intel on the whole can run at higher speeds they fair better in a bench mark (specifically a user submitted one). Who'd of thunk it?
