Geez I wish they would’ve used the 7940HS too. Would be nice to compare that as the Anandtech review had. Computerbase had 8945HS. Need a spreadsheet to do a proper comparison.Phoronix:
Seriously impressive efficiency gains gen over gen.

NBC has their review up of the Zenbook model. Battery life looks good, not really an improvement over what was already available, but is better than a similarly equipped Snapdragon Galaxy Book *(roughly equal when normalized for battery capacity)*.
Their Zenbook scores slightly higher than Anandtech's in single core tests and they have Proart numbers that score slightly higher than that. I think the Zenbook doesn't sustain single core boost and for some reason, Anandtech's laptop is hitting less frequency than others, which is decreasing their 1T Spec numbers a bit. Even with that, IPC is disappointing at < 10% increase, but it seems like they tried to balance performance and efficiency with STX. Desktop and server should have a bit higher IPC.
Overall it seems like STX is a minor performance bump, good efficiency increase, really good graphics bump, and good battery life. Nothing revolutionary, but an all around really good performer. It clearly leads the x86 space and doesn't have the issues that the Arm on Windows laptops have to deal with. Having the fastest NPU allows for laptop vendors to market it as the AI leader. Even if that doesn't really mean anything right now, with the AI fever going around the world, it's a great marketing point for them to advertise.

If you want to know how STX performs with higher power, you can go to the Zenbook review and look for the Asus Proart numbers. The review isn't up yet, but they have the numbers in the Zenbook charts. Not sure what the power consumption in the Proart is though.

Strix Point is much worse than I expected.
No point waiting for cheap Kraken Point when they'll only be ~10% better compared to existing 7/8000 laptops. Actually since it's 4+4 it might be worse in MT.

That chart is awful. They really need to work on presentation, lol. With that said, yes, it looks like it's low to mid 50s of Watts for 1100 pts.
It may be able to offer better efficiency. That seems to have been a focus for Zen 5 on mobile.

From Phoronix's 100+ Linux benchmark test:
These initial Ryzen AI 9 HX 370 results have me super excited for Zen 5. It's different having AMD shipping their next-gen laptop SoCs ahead of the desktop processors, but in a few weeks attention will turn to the Ryzen 9000 series. I've been pushing the limits of this SoC in being eager to test Zen 5, so stay tuned for more articles ahead of the Ryzen 9000 series launch. The generational performance uplift is nice with Zen 5 but really captivating my interest has been the large power efficiency gains at least among these laptop SoCs. The Ryzen AI 9 HX 370 also furthers its lead over Intel Meteor Lake that makes an even larger hill for Lunar Lake to climb, which will be interesting to see how that battle goes later in the quarter.

And iGPU is gonna be worse too with 8 CUs. You will literally have 10% better ST and a stupid NPU that can't be used properly.
Whatever it is that s still an impossible curve, there s no CPU whose perf increase linearly with power, that s against the laws of physics.
This and the fact that the 8945H gain only 10-12% perf from 35W to 70W lead me to think that this guy has no clue about power mesurements methodologies.
Same as NBC who put the 370 at same perf/watt in ST than a 185H, yet Computerbase measure 40-50% more power for the 185H in Cinebench ST at 28W while the 370 hoover at 18-20W.

Splitting core to 2 different CCXs really hurt performance. Still don't understand why they did it, it seems that doing one 8-core hybrid CCX solution would have been better alternative.

Yup. I thought the same. They even made a 7545U/8540U with 2+4c config with unified cache. Could have done something like that for efficiency rather than doing this.

NBC does power and perf/watt measurements for the whole system, which greatly obscures the differences in SoC power/efficiency.
Barely faster than a 780M with same LPDDR5x-7500? What happened? Bandwidth limitation too big?

The fact that a single CCX can only support upto 8 cores seems to be a problem for AMD. More cores would require another CCX, and a seperate L3 block. Perhaps they should work on larger CCXes, or even do a rework of their core cluster hierarchy?
For comparison, the ARM DSU-120 can support upto 14 cores in a single cluster, with a single block of L3 cache.

RAM bandwidth and GPU L2 size are both unchanged... meaning that it's essentially the same memory subsystem for the GPU as Phoenix.
That is what Zen 6 is to solve, I guess.
In Bergamo/TurinD it isn't a significant competitive disadvantage but it seems to be a problem here.
Also, that's not an M3 but an M3 Max for the white line. That's a slight 2.6x exaggeration in score.
Increasing the cores per CCX has very real latency, complexity, and power consequences. X Elite cores are clustered in groups of 4 for a reason.
Dubbious methodology, beside the 370H has an OLED screen while the 185H has an IPS, in ST where power is lower this has some impact, as well as in battery life, so all in all Strix numbers are quite good.
From the same review, I think this is a great achievement:From Phoronix's 100+ Linux benchmark test:

Where things got really interesting with the Ryzen AI 9 HX 370 was the power efficiency of this Zen 5 laptop SoC. Across the span of all the benchmarks, the Ryzen AI 9 HX 370 SoC was pulling about 20.4 Watts with a peak of 34.2 Watts.... Meanwhile the Ryzen 7 7840HS had an average of 35 Watts and a peak of 60 Watts. The Ryzen 7 7840U had a 27 Watt average and a peak of 51 Watts. The Ryzen AI 9 HX 370 came out faster than those parts while consuming significantly less power. This Zen 5 power efficiency is very exciting and should carry over for desktop and server parts too. Meanwhile the Core Ultra 7 155H was consuming 29.6 Watts on average with a peak of 65 Watts.
Yes, it is. The 600 dot at the bottom fits for the regular M3. Apparently that "M3" more or less means the whole family of M3 silicon.
