Nvidia has discontinued compatibility with OPENCL and CUDA of 32 bits For the series RTX 50and this is causing compatibility and performance problems.
Nvidia RTX 50 suffers compatibility problems with Passmark
Recently we talked about the RTX 4090 and as it was offering a higher performance to the GeForce RTX 5090 in Passmark, One of the most used benchmark tools. There were no reasons for this to actually happen, we know that RTX 5090 is faster than RTX 4090, so it didn't make much sense.
Apparently, the performance problem has to do with the decision of Nvidia of discontinuating OPENCL and CUDA of 32 bits in the RTX 50 series, which would be causing compatibility errors and performance losses in evaluation tools such as Passmark.
There are performance test problems Directcompute of Passmark, that is giving the error «Cl_out_of_resources (-5)» With a GPU RTX 50. The developers of the application began to investigate the matter and confirmed that, although the main application of the comparative test is 64 bits, several comparative comparison sub -computations still use 32 -bit code, which would only work with the RTX 40 or previous series.

At this time, the developer study of Passmark You are working to move the entire code OPENCL to language of 64 bitswhich should solve the low performance of the series GeForce RTX 50. It is also warned about the low performance of Directx 9, which is due to additional architectural changes can affect the inherited rendering paths.
Next, a previous benchmark is shown executed without the last patches of Passmark V11.1 Build 1004which shows the performance drop without the appropriate software.
This situation not only affected benchmark tools, but also technologies such as Physx of Nvidia itself. We will keep you aware of all the news.
