[Documentation]: Examples of hipDeviceProp_t::major value for different GPUs

[nazar-pc]

Description of errors

I was trying to find what values of hipDeviceProp_t::major correspond to what GPU and wasn't able to find it.
There are also seemingly no official CLI tools that print it, the only option is to own the GPU and write a piece of code myself.

I also tried to find in the source code and didn't succeed so far.

Would be great to have it described somewhere.

Attach any links, screenshots, or additional evidence you think will be helpful.

Hi @nazar-pc, hipDeviceProp_t::major and hipDeviceProp_t::minor reference the GPUs architecture. The system requirements page has a table which you can use to decode which architecture a GPU corresponds with. For example

An AMD Radeon RX 7900 XTX which is gfx1100 will have a major value of 11 and a minor value of 0.
An AMD Instinct MI100 which is gfx908 will have a major value of 9 and a minor value of 0.

Interesting, that makes a lot of sense to me, but wasn't obvious at all. Would be great to improve documentation in that respect.

Thanks for quick response!

No problem! I agree that the documentation could use some additions in regards to compute capability. I will reach out to the docs team and confirm how we want to go about adding it in.

#4350 and ROCm/hip#3721 have been merged. Both changes provide more context as to what the values represent and the expected output as well.
