Accprding to Computerbase the 370@33W match the 8945HS@75W in CB 2024, that s 0.44x the power at same perf, the estimations i did are right on the money.

Meh. Computerbase: 370@33W is 18% faster than 8945HS@37W. With 50% more Cores/Threads. iGPU is bugged af and Clocks below 2.5GHz, only 10-15% uplift in steel nomad light.

As fast at 33W than the 8945HS at 75W, that s the number to consider.

Beside 18% faster at 33W than the 8945HS@37W mean 24% faster than the 8945HS@33W.

No? That's just massive cherrypicking. If you run Phoenix that much out of sweetspot, it will probably lose to Rembrandt@35W, while being a full node ahead.

Which is quite bad for 50% more cores/threads.

That s the other way around, chips should be compared at isoperf, why should a device be required to do more work in a given time for a comparison..?..

Which is quite bad for 50% more cores/threads.

That way good enough to have the best chip by far, what matters is that at 33W it perform 28% better than the 185H@46W, i let you imagine the tiny power amount required to just match the Intel chip, because the competition is Intel, not Hawk Point.

You can do that, but it still doesn't gell you anything on the archs efficiency.

Of course Hawk Point is competition. These Strix devices nearly cost double compared to Hawk Point ones. All for 20% CPU and 15% GPU Performance and that stupid NPU.

That's just the usual AMD early adopter tax. These will get discounted in a mere few months.
Months ago we said Strix will be a new Performance Tier and Kraken will be the true Phoenix successor? What do we say now. Strix is barely a normal generational uplift to Phoenix and Kraken is set to be destroyed.

Btw. look at the Anandtech Review. ZEN5 has 0 IPC in SepcINT and 15% IPC in SpecFP.

ZEN5 definitely looks like AMDs 2nd slip after RDNA3.

Phoronix:

When taking the geometric mean of the 100+ benchmarks run for this launch day article, the Ryzen AI 0 HX 370 was overall about 10% faster than the Ryzen 7 7840HS and about 18% faster than the Ryzen 7 7840U... Not bad, considering those prior Zen 4 parts were all Zen 4 full fat cores compared to the Ryzen AI 9 HX 370 having four Zen 5 cores and eight Zen 5C cores. But across a variety of real-world workloads especially among creator workloads and more, this Strix Point laptop was delivering great uplift. The Ryzen AI 9 HX 370 also came in 43% faster than the current Intel competition with the Core Ultra 7 155H "Meteor Lake" processor.

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.



Seriously impressive efficiency gains gen over gen.

Yeah but not really ready for usage under linux until later this year unfortunately...

From the Phoronix review;
Another item to be aware of is the heterogeneous core topology handling. AMD engineers have been working on AMD P-State patches for heterogeneous core topology CPUs but as of writing the patches haven't yet been upstreamed into the mainline Linux kernel. These patches should help with better placement of processes onto the Zen 5 cores rather than Zen 5C. But as these patches weren't picked up for the Linux 6.11 merge window, unless they end up being submitted as a "fix" for Linux 6.11, that means they won't be merged until at least the Linux 6.12 kernel cycle. Linux 6.12's merge window will be in September while that stable kernel won't be out until near the end of 2024.

Which is kinda fine for me as it allows me to have an excuse to wait for Strix Halo

There's no reason for these NPUs right now.
Yeah, but then that's a complete fumble on AMD's side. Pushing AI in every single presentation and then having nothing to show on release. As usual, they did everything for Microsoft only for Redmond to completely ignore them regarding CoPilot+ support. But it would have been nice to at least work together with the developers of the Procyon suite to get XDNA2 support on launch day.

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.
