As some of you know, my laptop died nearly 2 years ago, and I've been working on a desktop machine, which is currently a Zen 3. AVX512 has become more popular in the meantime, with Zen 4 and future AMD CPUs shipping with it, but currently, we have very little AVX512. In short, I'd like a machine which runs an AVX512-capable AMD CPU, and as the world is opening up more and more, I'd like for it to be portable.
I've looked around a lot, but as Intel still has a firm monopoly, the options are limited (7940H(S), 7945HX, 7845HX, 8945HS). What I think I've settled for is an ASUS Vivobook Pro 15, with a 7940HS CPU (the second least powerful Zen 4 mobile CPU), currently trading for 1999.0 EUR on amazon.de. https://www.amazon.de/-/en/Vivobook-Display-R9-7940HS-Windows-Keyboard/dp/B0BRYTS8MR The other alternative I've found is a Lenovo Legion 7 Pro, but it's more expensive at 2399 EUR (currently seems temporarily discounted due to the holidays). The Lenovo IdeaPad still hasn't been refreshed and uses a Zen 3 CPU, so it doesn't fit the requirements. I'd take other options, but after all the looking I did, the only other laptops to feature Zen 4 CPUs are rather pricy gaming laptops with high-end NVIDIA GPUs, starting at 2500 EUR and going up. I'd be happier with the Vivobook. The OLED screen is a nice bonus too. I'd be open to ARM-based Apple laptops too, but we already have a shared M1 machine, and I'm not really a big Fedora fan. RISC-V is obviously still out of the question at this point. As for my plans for AVX512, I'll first add limited 32-register version of the FFT, which wouldn't be too hard to do, and looking into modifying the existing recombination function to work on 16-point basis. I'll also look into modifying other trivially extendable code like the float_dsp. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
