GPU on Librem 5 is actually faster than on X220? Good. I proved to myself that 1Mpix/30fps is possible. Now for the boring task of actually getting it to work... #linuxphone #librem5

@pavel that wouldn't surprise me, the Vivante GPU is pretty capable and the X220 is pretty dated (and Intels GPU performance usually sufficient but not great)

@agx X220 is still second-best notebook, ever :-). Yeah, its old, but I kind of assumed TDP difference would make up for technology difference. Part is that Intel GPU insists on producing RGBA data, and I need RGB data.. and that was slowing things down. Anyway, good for Librem 5.

@pavel I didn't want to pick on the X220 - sorry if it sounded like that.

Just wanted to point out that i.MX8 is pretty powerful in that regard (also with the DCSS display engine for actually outputting e.g. video, etc)

@agx No, you are right, X220 is old hardware. But I like the keyboard and it is powerful enough ... so I use it.

I assumed relative power of CPU, GPU and memory would be approximately similar... and clearly that's not the case. Which is a good thing, 512x384 might be doable on Librem 5's CPUs, but that's really quite low.

@pavel I thought I was the only one who still had a Librem5

@BeardlyDavid Nah, there are few of those around. They are still best "development board" available for camera development.

@pavel I still hope to see it become usable.
