That is an interesting topic, the graphics performance i mean. I was gonna say ARM soc + graphics = bad combo, but then i realized, all the best cell phones in the market also have ARM socs. Qualcomm and Mediatek can put such powerful chips inside these phones that they can play 4K, and run seriously hefty games. But of course they do that on a very small screen. So the question is, if we scale it up, would they still perform? I guess so because those small screens have 4K resolutions (it is like a joke). And how much extra would it cost to get a Mediatek SOC on a Pi for example? Having said that, what about an X86 SOC?I got two impressions from RPi5
1st is that the CPU is pretty speedy and runs pretty much like first gen Core i5 750/760. After OC it almost gets to Core i5 2500 (non-K) so its pretty amazing given such PCs are still pretty usable even today. SD card flies on this Pi and everything is very snappy. It boots quick, X11 starts quick. Absolutely impressed by what I see.
2nd is the GPU...
So far from what I can see the GPU is absolutely horrendous and completely does not fit the levels of CPU and I/O performance I am seeing otherwise.
Openarena runs so bad I would expect to get better performance out of Voodoo 3... heck, Bashnee even. Its ~60fps at 640x480 and no, its not due to v-sync and I also tested it in both X11 and Wayland. With V3D at 1150MHz it was 67fps, lol.
Dhewm3 (Doom3) runs more like some kind of GeForce 6200/Radeon 9550 or something, maybe better but not much better. Not sure how its possible to have 1GHz GPU with supposedly more than 10 pipes to run as bad as this one does.
Anyways, GPU is not the strong point of this SBC. Since however there is no such thing as games on Linux on ARM and all the games I can play on something else its not like it matters. At least not until we can still comfortably use X11. Wayland as can be already seen requires quite more powerful hardware than Pi has and why it probably lags so much. I do not think core issues with lag with Wayland can be resolved with such weak GPU.
ps. BTW now I understand why Jeff wants external GPU on Raspberry Pi so badly
