Some people complained that 2 GHz sounds little. I thought that hmm, I remember when desktops didn't break 3 GHz for year, and once they did they became hot enough to fry eggs.

But then I checked, and my refurbished new old laptop actually has 2.8 GHz. Is a 2 GHz RISC-V of this brand good enough to watch 1080p x.265?

@notclacke I can't find the specs on the SpacemiT site (I'm using the integrated Google English translator, so it might be hiding some links). However, the specs are listed in the BananaPI docs (https://docs.banana-pi.org/en/BPI-F3/SpacemiT_K1). This is the 2nd generation of the only RISC-V laptop I'm aware of, so I view it more like a portable RISC-V development system for OS, drivers, and apps. Yet, it does seem to have decent multimedia capabilities. I suppose it also depends on how well Ubuntu is optimized for it.

@notclacke P.S. - The Intel 10th Gen Core i7 8565U quad-core / 8-thread chip in my Lenovo ThinkPad X1 Yoga from 2018/19 has 1.8MHz / 4.6MHz Max Turbo cores. I'll run a 1080p video and check the core frequency.

Playing either a WebM AV1 or MP4 H.264 video file at 1920 x 1080 full-screen averaged about 1.30MHz for all cores. Both hit highs around 2MHz when starting the video and then dropped in CPU usage. Playing both at the same time averaged about 1.8MHz.

Thank you! I found www.cnx-software.com/2024/04/30/muse-book-laptop-spacemit-k1-octa-core-risc-v-ai-processor-16gb-ram/ which states clearly that the SoC itself has: "VPU – H.265/H.264/VP9/VP8 4K encoding/encoding"

And then the question is just whether mplayer/VLC/GStreamer supports that hardware too.

I understand that a media center is hardly the intended use case, and I couldn't care less for the advertised AI support. But if I were getting a laptop anyway, and there'd be one that runs RISC-V and accidentally supports my use cases, I'd definitely support that rather than further supporting ARM and x86-64 laptops capable of running Windows.

@notclacke Thanks for the info! 👍 I didn't realize the DeepComputing Roma Laptop II was based on an OEM product from SpacemiT. I checked SpacemiT's Web site again & noticed they offer three products (probably all OEM for other companies to brand)...

Unfortunately, I can't easily translate the pages to English - the written text is in JPEG images. 'Need to OCR it.

I'll add your link to my OP
