Meanings of Throughputs in GPU Trace

[stezkamilan]

Hi,

is there any source of information on the meanings of the Throughput values in the GPU Trace? To be precise, I fail to find any explanation of the PROP Throughput (I know that CROP is Color Raster Output and ZROP is Z-buffer Raster Output). More detailed explanation of all the other graph values would be useful too. The tooltips don’t cut it most of the time. I am currently scavenging information here https://developer.nvidia.com/blog/the-peak-performance-analysis-method-for-optimizing-any-gpu-workload/ and here https://docs.nvidia.com/nsight-graphics/UserGuide/index.html#gpu_trace_ui Especially these official docs should have a section dedicated to this, but I don’t really find any detailed explanation.

Thanks

Hello,
Thank you for using Nsight Graphics and your question on getting detailed explanations on some of the metrics that GPU Trace reports. Here are some additional links that will provide more information on the throughput metrics that GPU Trace supports.

See GPU Trace Feature spotlight video: NVIDIA Nsight Feature Spotlight: GPU Trace - YouTube

See Louis Bavoil’s presentation: https://news.developer.nvidia.com/what-is-limiting-your-rendering-performance/

Even though I don’t understand why this kinds of documnet is provided by Microsoft – not NVIDIA --, here is useful link including the answer what is PROP.

Hello,
Thanks for your question and link you provided on the PROP metric. We also provide documentation here Advanced Learning :: Nsight Graphics Documentation. Hopefully, this will help to provide additional insight.
