Cuda texture size limits rtx 6000 ada

Hey all,

Not exactly a developer but I was directed here from NVidia general support.

What is the max render texture size on the ADA generation?

I was able to find an answer from many years ago (2007) in this thread, and I’m wondering if there’s a similar answer for today’s hardware (specifically the RTX 6000 ADA)

Thanks so much!

For CUDA, various texture size limits are indicated in the deviceQuery sample app, and are also documented here (numbers for cc8.9/Ada):

Maximum width for a 1D texture reference bound to a CUDA array: 131072
Maximum width for a 1D texture reference bound to linear memory: 2^28
Maximum width and number of layers for a 1D layered texture reference: 32768 x 2048
Maximum width and height for a 2D texture reference bound to a CUDA array: 131072 x 65536

And there are other various limits that you can read at the link I provided.

This is for CUDA. If you are asking about OpenGL, you should ask on an OpenGL forum.

Thank you so much!

I guess the app should be changed to refer to texture objects, as texture references have gone the way of the dodo, and more recent CUDA users may not even be aware of the previous existence of texture references any more.

I have filed an internal bug (4640920) to have the docs updated.
