Please tell more why progressive sampling is using less memory than bucket mode

[Micha]

Hi Muhammed_Hamed,

I read your recommendations today and was surprised that the bucket mode is not suitable for keeping memory consumption low. Can you say more about this? I was expecting the opposite. When is bucket mode an advantage at all?

I recommend this thread by Lele. I think it's pretty much the same for GPUs.

Thank you, flat, nice article. Now I'm curious to see what Muhammed_Hamed says, because he says the opposite about memory usage, very interesting.

GPU buckets are different than CPU buckets, GPU buckets use more GPU memory compared to Progressive. You should see that in every project.
V-Ray GPU started with Progressive mode back in the day, it works well with high-end GPUs and is very efficient on using GPU memory.
GPU Bucket mode could be helpful for Distributed rendering or very high resolution rendering to save system memory

Best,
Muhammed

Great, I like the progressive mode much more. Thanks for the details.

My understanding was not clear enough, sorry.
It was good to know that buckets are more memory intensive on GPUs.
