First Core Ultra 7 355 benchmarks are in and they're nowhere near as good as the Core Ultra X7

Panther Lake-H has proven itself to be quite impressive thus far, but the lesser Panther Lake-U series loses a lot of what makes the architecture unique from predecessors.

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

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.

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?

Is 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?
