No, it cannot decode 4K AV1 smoothly without hardware acceleration.

The I7 8550U can handle 4K AV1 decoding, and you can cool it passively with just a heat sink. For the I7 7500U, it’s also suitable for video playback.
AV1 needed specialized hardware to encode, which software like H.264 can't replicate using just the CPU. I clarified this in my reading. Apologies for any confusion. Edited June 1, 2023 by SorryClaire.
They include an integrated GPU regardless of preference, and using regular processing would create excessive warmth unless the cooling solution is significantly oversized to accommodate a laptop-sized unit.
it's not a laptop, hp has used those cpus in some elite desk models which are a bit bigger than your hand. i question whether the i-gpu in those lines—6, 7, or even 8 cores i7 and i5—can handle hardware decoding for av1. I might be able to purchase some of them at a lower price and think about turning them into something practical like an htpc.
Several AV1 CPU encoders are available without requiring special hardware. Decoding can also happen on the CPU, though results may vary based on video quality and player performance. Using passive cooling is recommended; compact coolers might cause throttling. For instance, my 12100F runs at about 35% usage across all cores (~2.5GHz) while playing a moderate AV1 video (4K, ~18.8MB/s, 23.976FPS) with VLC or mpv, staying around 2.1GHz but with slightly higher load (~42%). It likely drops frames noticeably. Intel introduced AV1 decoding in the 11th generation, so these older CPUs don’t support hardware decoding.
Yeah, but quality also isn't as good on HW encoder/decoders, even the best H265 HW encoder still looks like shit compared to x265 when comparing high quality videos encoded to similar filesizes. In general, for archival and higher quality playback software is better, for speed and low power consumption hardware is better.
