Raspberry Pi GPU?

Postby owen_a » Mon Mar 23, 2020 3:06 pm

Hi,

Is it possible to add the Raspberry PI GPU? I believe the one the Pi 3 uses is a Broadcom VideoCore IV chip.

Be interesting as a lot of people have spare PI's laying around (I know I do anyway) and since the GPU will be much faster than the CPU it could help contribute quite a bit to projects.

No.

AMD funded the AMD GPU client, Nvidia funded the Nvidia GPU client, Sony Funded the PS3 client and the Android Client.

I see no one with deep pockets to fund a Raspberry Pie client.

If you have a large donor in hand, I see two technical problems: F@H needs at least OpenCL 1.2 and it needs a GPU that can do Double Precision floating point math.

I see the Pi using a subset of OpenCL, and do not know if that subset is enough. I can't find anyone discussing the math capabilities of the GPU.

Fair enough, worth asking just in case. Thanks for the reply.

Plus anything ARM based (CPU or GPU) is basically not designed for intensive computing but for low power applications.
