I wonder, now that the Strix results are out, if folks will perhaps use a tiny bit more skeptical thinking when someone on a forum starts claiming Zen 6 will offer +85% iso-clock perf or whatever.
Orrrrr you just ride the HYPE train till launch and then cope with the retail performance...

Zen6 50% PPC incoming ??!!

We already have the Zen 6 estimate of 10% from the same slide that had Zen 5 right so there is little chance we can get a good hype train going even if the usual suspects try.

Everything is really weird. In NBCs Zenbook S16 Review, there is a Cinebench 2024 result (1099 points) of ProArt, which isn't in the ProArt test itself. 1099 is only 10% higher than Computerbase result of 33W Version.

Guess that they are messing with the power profiles, if around 30W the score is about 1000 then at roughly twice the power it should be at 1400, or possibly that NBC made their CB 2024 run while the laptop was still very hot, wich could explain the 10% only better perf than Cmputerbase.

Holy bizarre cow.
Yeah, it's really strange. He even talks how "the ones with the lines" were laptops where they tested all power levels on the same device, and then doesn't notice that this puts the white line in a strange spot. Later, he explains how with Apple you basically can't change the power consumption, but you buy another device if you want more performance. So yes, the white dots absolutely are the fixed values for different M3 chips.

That being said, @Hitman928 could you perhaps not only remove the question marks but also the white line between the white dots? 🤣

Something funky going on with that int score looks like (the HXL dude pointed this out):

Looks more normal there:

From the tests so far, it seems like the Zenbook model doesn't allow the HX 370 to sustain its single core boost. Add to that, the 7940HS has a 5.2 GHz boost versus 5.1 GHz of the HX 370, and you are looking at ~7% IPC increase, assuming the 7940HS holds its single core boost and the HX 370 at Anandtech is ~5 lower than boost clock (according to other ST tests from other outlets). I think this actually matches the previous ES Strix measurements done for Spec Int IPC.

Since you asked nicely, lol. It's quick and ugly but here you go. I also added a fitted line for the HX 370 and X Elite, though it's just eyeballed and the lower power levels for the X Elite numbers are weird. I'm guessing it's different SoCs at the bottom, similar to the M3 issue.



Edit: redid the fit lines.

There's a problem with that Math and that Problem is ZEN5c. Clocks of 8 of the 12 Cores are Limited to 3.7GHz. Computerbase got an avg core clock of 3.43GHz at 33W. So starting at 40W, there's only 4 of 12 Cores that can scale further. So basically at that point every scaling is gone. Even if those 4 Cores got to 5.0 GHz that's only a 11-12% uplift over 40W. No matter how much power you throw in there. 1400 isn't possible.

It's even worse for 365 SKU, where ZEN5c is limited to 3.3GHz. I suspect limitations starts at about 25W here. So scaling is dead starting at 25W, however it's 4 of 10 Cores that continue scaling, so it could gain 20% at Max power compared to 25W.

Shouldn’t that affect the fp score as well? Seems particular to just int.

~5, percent?

GPD displayed a run that scored 1525, so that s outright possible, beside the 8500G APU wich is 2 + 4, so half the 370, can go above 45W according to Phoronix review.

I have doubts for actually ran this themselves they just copied those numbers from cpu-monkey who just applied amd 17% ipc uplift to zen 4 numbers

The darker purple HX 370 ones are from two different models, one more geared to being quiet, one towards higher performance. The X Elite numbers are estimations since HWiNFO still has no way of reading package power for the Qualcomm chips. So JustJosh had to go from wall power readings and then substract estimates for the notebook baseline based on models as similar as they could find. But they say that the yellow values are probably best case values for the X Elite.

The main conclusion of the video is "If you're not buying Apple, get Zen5". Strix clearly makes the X Elite obsolete. CPU efficiency is just as good or better with Strix, and the performance advantage (and compatibility) of the iGPU is even bigger. And at this point we don't need to talk any more about Intel until Lunar Lake arrives.

Good catch, those are just CPU Monkey numbers which are known to be made up, specifically for pre-release hardware. We have actual tests now that show that 1525 is not happening. Even 1400 is out of reach.

That s the other way around, CPU Monkey collect numbers here and there that they use for their database, not the first time they did so, they often use numbers that are allegedly leaked even before there s proved tests.

And in case you dont know GPD manufacture devices using AMD APUs,
why would they need to rely on obscure sites since they have ESs long before the consumers have access to actual products..?.
