an AMD exec said that AVX512 and VNNI acceleration built into the Zen 4 CPU cores were behind the winning results you see in the charts That's what makes this a bit weird. The NPU yadda yadda is all possible, but those need specific coding over just using the CPU. So I'm not surprised they showed the CPU results because that's probably an easier benchmark to get going. But why is Ryzen winning there? Zen4 AVX512 support is no faster than AVX2 code due to the internals (mostly, aside from shuffles!) being 256-bit. VNNI is a nice win, and Zen4 has support for AVX512VNNI, but Alder Lake and later class chips have AVXVNNI, which again, due to the above, really runs just as fast. So this result really doesn't have anything to do with any AI acceleration on either chip - they basically support the same at the same performance. So what the benchmark then really shows (assuming no shenanigans like using AVX512VNNI on Zen4 but no AVXVNNI on the Lakes...) is either faster clockspeed due to power envelope, or (common issue for LLM) better cache subsystems. The quoted claim from the article makes no sense. More on reddit.com

They actually stack up quite well since this is H vs. HS. I don't have either of the CPU's available in the AMD version, but I have a laptop with the 155H, and laptops with 7840U, 7840HS, 7940HS, 8840U. Given the EXTREMELY minor difference between Phoenix and Hawk Point (1 NPU core), they're quite relevant. The AMD's are still a little more powerful in the HS vs. H. My 7840HS in benchmarks routinely surpass the 155H, although the margins are quite small. The iGP's are insanely close. The Arc Xe 8 techncally has the more poweful hardware, but while Intel is improving their drivers all the time, they are still the weak link for the Intel iGP's. Efficiency is out of the box weak for both of these laptops. But both respond VERY well to power saving settings. In the end, I'd take the Intel due to the panels. The WQXGA LCD is just so amazing on a 14.5" screen, whereas the AMD has only WUXGA or 2.8K OLED. I had the 2.8K OLED on my 7840U thinkpad at first, and I absolutely HATED it. Bad battery life, horrible looking text when fractionally scaled. So that's my preference. More on reddit.com

I thought it was going to underperform but Intel has done a nice job here! Curious as to whether we’ll see more laptop supply with Ryzen APUs once Ryzen 8000 releases now that AMD actually has competition in the iGPU and power efficiency sectors. More on reddit.com
