Must state the obvious obligatory different GPUs, but further than that-- does anyone remember some techtuber/leaker saying they saw something really weird in CP2077 with either Zen 5 or 9700X (dont remember which)? Somebody help me, I cant recall who it was but I distinctly remember it. This could be what they were alluding to.
It was the italian guy and i also mentioned it here on the forum.
Also dude you still on the copium train... 6800xt doesnt magicaly net 60% better minimum fps and 15% avg. Also i just benched with fsr off and exact same settings as the chinese i have even better scores then previous screenshot... Cant find the HUB video where he compared amd vs nvidia with cpu limited scenarios and i think it was somwhere in 5-10% range.

Whoa, whoa, whoa mon frere, what copium? Im not making excuses, just pointing out its not exactly apples to apples-- in any case thats completely secondary to my point about the Italian guys comment about CP2077. What more do you know about that? I could care less about the differences in the GPUs, I know they shouldnt cause those kinds of differences in the averages. Mins can be caused by many, many things. What do you mean you benched? What CPU do you have, X3D or 9700X, lol?

Point is, it seems to me that CP2077 and Zen 5 (desktop at least, Strix seems to perform OK?) seem to not play well together for some reason, is it copium for me to assume that it could be game engine vs brand new architecture related and could possibly be fixed with a game patch or AGESA / driver update, or should I just say "Zen 5 desktop sucks!" and stop asking questions?

So it seems everyone is flopping except Apple.
it’s seems the M4 has the highest overall ST performance increase this year, kinda funny considering how Apples CPU team is slowly growing again after the exodus.

But it funny how the X Elite couldn’t even match M1 in terms of IPC, looks like there is more to Apples cores than Gerard Williams.

Strix is very competitive in the x86 landscape. One has to wonder Strix improved massively in terms of battery life over Hawk Point so Lunar Lake has to beat that and it will be difficult.

... on tuned SME, sure. This is a stretch. M4 was a fine rev but not with any kind of breakthrough iso-clock increase. It was a clock bump with some tweaks.

And more to microarchitecture than iso-clock perf.

Same settings as the leaked 9700X cyberpunk bench. (I even picked the best one for 9700x). AMD official slides showed watchdog -6% vs 5800x3d stock vs 9700x stock. So it wouldnt be crazy to assume that it could also be slower in cyberpunk.
Even if you disregard the minimum fps on the chinese leak (i had this fps drop on 1.52 patch for ~1-2sec near the palm trees) and he would have same minimum fps as me he would still be lower in avg. Lets even give him +10% for hw scheduler still slower...
Im running 2000fclk 4000cl16 -22CO and hitting 4450Mhz all the time so im not stock.
Anyone with tunned 5800x3d/7800x3d and RTX 4070ti/4080/4090 care to bench ? LOW preset fsr/dlss off 720p

What is surprising here? It's the first uarch from their startup's roadmap. I think people underestimate how much continuity and having past designs to use as foothold and ready tech reservoir is important. It's great achievement they ended up with competitive performance. (people really should completely disregard all that BS about beating everybody 2x over from those old misleading Nuvia blogs).

It’s an ~7% IPC increase and 10% clock bump. M4 isn’t groundbreaking yes but it’s an evolution over M3.


Its also very potent on non-SME tests like GB5:

I don’t see either Zen5 mobile or ARL/Lunar coming close to that. Even the 9950X couldn’t beat it on stock.

Qualcomm was also quite misleading but yeah their 2nd gen should be much better.

No. Zen 5 isn’t bulldozer but it’s also not the mythical core that Apple etc will take years to catch up to. That assertion still annoys me.

Jim Keller of all people LIE to us.

Still, let's wait for Zen 5 on the desktop, but I'm not optimistic.
I can't help to think that AMD got really lucky with all this Intel situation.

Yes, I've been having the same feeling lately. Also with RDNA2 being competitive with Ampere as opposed to RDNA3 vs Lovelace, and the almost complete cancellation of RDNA4.

I think that the stock market has had the same feeling, where in a year still in the AI boom and all that - Nvidia has more than doubled its market cap (ytd, after more than tripling already in 2023) AMD has achieved a 1% gain (ytd).

Here is what David Huang got for Spec 1t and IPC with an ES sample when equalizing clocks.



So a 9.71% IPC increase and the GCC test actually improved by 10.4%. I estimated 7% from Anandtech’s data with a rough calculation of actual clock speed difference but actual clock equalized tests are obviously better. Still a bit underwhelming, but combined with the efficiency increase, it’s an overall good result, just a let down after all the hype. The desktop variant should have higher IPC, it’s just a question of how much.

David Huang was not using an ES. It was a retail sample.

I don’t get how having a worse generation uplift than Zen 4 is a good result when you take everything into account.

I feel like there is huge disparity when AMD fails and don’t reach expectations compared to when Intel, Nvidia and Apple fail. Not directing this at you but it’s something I noticed here and other online forums/twitter.

The amount of crap Apple got for that 7% IPC improvement over 7 months mind you not even 22 months like AMD is certainly constitutes favouritism. Comments like Apple’s CPU team dead and ARM is dead but when AMD doesn’t reach expectations then its “design is hard”, they focused resources somewhere else, Zen 6 is the one to look out for etc.

10% increase in IPC is 5% YoY, so is AMDs CPU team dead no it’s not, so maybe Kepler and the “x86 gang” should not make statements like how Intel and AMD increase IPC 10% YoY which is certainly not true.

Precisely. I guarantee this forum mocks Lion Cove relentlessly when it launches with similar performance increases.

Should it? That 9.71% you cite is int IPC, and nothing in Zen 5 desktop is going to increase int IPC. If anything, it could end up lower since AMD is reusing the IOD on desktop, and Strix may contain uncore improvements.

Floating point uplift will be higher on desktop when AVX 512 is in use, of course.
