Interesting things happen when you add dell plus 14 2in1 with Ryzen ai 350.
AMD based laptop beats core 7 355 by 3-40% in all but one benchmark with average lead of 4% while drawing 20%(39 Vs 49 W) less power on average and nearly 30% (55 Vs 79W) lower peak.

And AMD ones not have 1hz refresh rate special screen to lean on...

Quote from: Sivious on Today at 15:13:03The article implies that the X series chips also have better CPU performance compared to their non-X counterparts, which I would suspect is only true in this case because this particular X series chip has more cores.

Don't worry, X means that the APU has the Arc B390 iGPU (see mentioned Wiki or what Dave2D said). X has more Xe iGPU cores, but the same number of CPU cores and almost the same clock = almost the same CPU performance (maybe a ~5% difference). The article may be a little bit click baity, or sensational, so that people click it [and then maybe the ads].

Quote from: Sivious on Yesterday at 19:03:18Is it just because the 355 only has 8 cores vs 16 on the X7 358H? I'm curious if there would be a difference between 386H and X9 388H in CPU performance if they have the same core count?

9 386H (4-core iGPU) vs X9 388H (12-core iGPU)?
X means it has the Arc B390 12-core iGPU, but the CPU performance should be pretty much the same (only a 100 to 200 MHz difference, see en.wikipedia.org/wiki/Panther_Lake_(microprocessor)). If you care about the iGPU performance too, the 12-core B390 iGPU is almost 3 times faster than the one in the 386H.

I (and the article) were pretty clearly talking about CPU... obviously the 386H will have worse GPU performance, but it generally comes with a DGPU that that is less important. The article implies that the X series chips also have better CPU performance compared to their non-X counterparts, which I would suspect is only true in this case because this particular X series chip has more cores.

Articles like these are the reason that the best x86_64 mobile CPU, the 258V was slept on so hard.

So what did you just receive the notebook,run cinebench on it and look at hwinfo for some power consumption numbers?

They paid you for that?

What a stupid article. 355H is entry level with only 4P cores and no E cores, and 4LP-E cores. E-cores of which the 358H has 8, are very powerful, with the same or better IPC than Raptor Cove P cores. So the 355H will literally have at best 40% of the performance as the 358H as the LP-E cores are useless for real workloads.

The only quasi-sensible comparison would be maybe against 336H.

A lower clocked 8-core chip with less cache is slower than a higher clocked 16-core chip with more cache? Now that's something we don't see every day!! https://giphy.com/gifs/producthunt-mind-blown-blow-your-26ufdipQqU2lhNA4g
