What is this?
This company makes GPUs?
- snvzz 3y ago>This company makes GPUs? Yes, and they've been around for a while. If you're old enough, you might remember the name "PowerVR". Today, they mostly license GPU designs to SoC vendors. You'll find their designs in e.g. Android phones. Notably, JH7110 (RISC-V SoC used in VisionFive2 and Star64) uses one of their recent GPUs.
- vitaminka 3y agodoes this mean you can run, say, modern openCL code on smth like a VisionFive2?

Note that rPi's is known to be anemic due to serious memory bandwidth bottlenecks, barely able to keep up with filling a 1080p screen. Currently they do not support the specific variant used in JH7110, but they seem to both be variants of the same architecture. JH7110 has the BXE-4-32MC1[0], whereas the driver currently supports the BXS-4-64-MC1[1]. No idea about compute, and AIUI openCL suport in mesa3d is still a disaster for all drivers. 0. https://www.imaginationtech.com/product/img-bxe-4-32-mc1/ https://www.imaginationtech.com/product/img-bxe-4-32-mc1/ 1. https://www.imaginationtech.com/product/img-bxs-4-64-mc1/ https://www.imaginationtech.com/product/img-bxs-4-64-mc1/
- FullyFunctional 3y agoI'm curious how you can tell that it was BXS-4-64-MC1 that was supported. I looked and couldn't find that. Besides the JH7110 there's TH1520 and it's using the BXM-4-64-MC1, also not supported, but 2X the speed of BXE-4-64-MC1 if I understand it correctly.
- vetinari 3y agoYes; and if you used an iPhone before 2017, you used GPU made by them.
