TF-GrayWizard on techpowerup explained how to manipulate cpuz scores. For Ryzen run the avx512 beta test then change back to the version 17 test, but don't run it and you can choose whatever you want to compare with. It will keep the avx512 results. Heres a 7950x3d faster than a 7950x and 13900k. I don't have my 14900ks installed anymore so I can't see if it can be faked easily with the various avx tests.

Also threw in a 7950x as well.

I asked my guy about it, he said he was just messing around with it. He re-ran it without touching anything.

Ask him to lay of the LN2

Does the distance look correct here ?

In the screenshot above the cpu string name seem to be centred..

This is how its supposed to look like: (7950x with fake avx2 score)


I am 100% certain the screenshot is unaltered
In my eyes this is clearly not a legit run..
Can we please stop with these CPU-Z benches ?

My screenshot taken from my own video here: but i also ran a much older version of CPU-Z so maybe things have changed (?)

Edit: I took a look at my 7950X, the CPU name string has trailing spaces causing it to be off center. Maybe the 9950X CPU name does not?

very true, disabled it (core isolation/memory integrity) and everything feels way snappier
Not sure that should happen outside of placebo, the effect on geekbench scores is just couple percent IIRC. I never really looked into testing the impact though, I just have it on all the time (except when I wanted to turn it off for such benchmarks).

Anyone who has ever complained about Geekbench being "synthetic" or "not running long enough" or whatever sure as heck should not be paying any attention to CPU-Z. It is a a single test, basically like ONE of the subtests in Geekbench, but far worse than those because it is so incredibly simple (implementing a two dimension noise function) which would fit into even the tiniest L1 cache.

So who cares if it is easy to fake or not. It is absolutely useless as a test of anything meaningful. I'm not sure one could argue it is better than Dhrystone, other than it uses a bit of floating point.

Use CPU-Z for what it was intended for, and ignore the useless "Bench" tab.

It's not that useless. It's the quickest way to see the effect of overclocking. And its AVX2 test is kinda dangerous coz it caused a very audible and ominous coil whine on my server mobo. No other benchmark I've run has done that. Don't underestimate it.

That's just a pro sku, you won't see it in any store. AMD released it early to cash in on the AI hype in the corporate sector

The regular Ryzen 7 1360 probably uses kraken die (4+4, 8CU), and will be released much later
Well that SKU is probably a successor to the cheaper 6 cores Zen4 units, so if we look in that perspective there could be improvement.

It's a successor to big phoenix (8c), not small phoenix. They reduced the number of CUs to fit a 50 tops npu, and upgraded the cores from Zen 4 to a mix of Zen 5 and Zen 5c
Phoenix and Strix Point are both "Premium Mobile" parts according to AMD (Fire Range being a desktop replacement part and Strix Halo a completely new segment for the X86 market). Of course Strix will target also higher performance (and thus price) but there is some overlapping. The SKU in the test can be completely substituted by the top Kraken Point part, which will be identical in performance and power, even higher because the Ryzen 160 tested appears to be a 3+5 part instead of the 4+4 in Kraken (KP die is not out yet, of course). Graphics seems likely to be cut down on both compared to top Strix, this 160 PRo part may even have less CUs than top Kraken as someone says it will be a 12 CU part. It seems they will have the same NPU. So why the Kraken Point should be a successor the the 6-core Phoenix but the same/lower performing cut-down Strix cannot?

Pretty sure Kraken is also supposed to be 3+5 and the bin 2+4 ( -1 , -1).

Kraken is 8 CUs. Bin is 4CUs.
Pretty sure all the rumors so far gave Kraken as a 4+4 and not 3+5.
As I said, some rumors said KP would have been 12CU (I also believe it to be 8CUs). As AMD gave no specs for the Kraken Point die, everything is in the rumor mill.
