Wouldn't the H.264 BR results be more indicative of CPU/RAM? From the PPBM Test Methodology page:
"H.264 test:
Here the speed of CPU/RAM communication is king. Number of cores, clock speed and the amount of CPU cache are very important. Dual processor systems are somewhat hampered by the 2 chip communication, but mostly by their clock speed."
Interested in your response because you guys know a lot more than I do about this stuff. Here were my results with the GTX 1080:
System:
3930K OC'd 4.4GHz
32GB DDR3 1600
P9X79
GTX 1080
OCZ Vertex 4 256GB System Drive
Kingston 120GB Cache Drive
3x1TB Samsung 850 EVO (Windows Software RAID0) Project Drive
Many Backup HDDs
Corsair H80
If you want improved Premiere Pro GPU performance from an nVidia CUDA card you do not have to adjust the GPU Core speed. All you have to do is boost the Memory Clock speed. Here is my GTX 1060 SC overclocked to 2400 MHz. To get to this actuall speed use your Overclocking tool to set the Memory Clock to 2500MHz, for some reason nVidia down clocks it to 2400 MHz when any CUDA application is running. The Memory Clock is really the only help with CUDA applicsations. You can also see that the other settings Power, Fan Speed are still all very conservative even under high GPU loading.
that's my Premiere Cuda export...
and here is stupid Gigabyte utility
so this 1060 has 8000MHz memory clock or I don't understand what you're talking about
but in GPU-Z i see max about 2300MHz..
If you use a tool like Speccy you can see that there are 4 different levels of Memory Clock/Shader Clock speed. For some reason the drivers for CUDA applications are limited to Level 3 so you will not see Level 4 for Adobe software.
Now just to confuse you more you will also notice that there are 3 different ways of specifying the Memory Clock frequency. Some tools like GPU-Z use the true base frequency like below: Notice the Default Memory Clock on my card is 2002 MHz, but it was overclocked by me to 2502 MHz but to further complicate specifications if you look a the Sensors Tab you will see that rather than running at 2502 MHz it really is 2399.6 MHz because it is restricted to only run at Level 3 as you saw above. Now some people like the larger numbers so they use 2x the clock rate which apparently is the real Memory Clock. Notice below that GPU-Z shows the default Memory clock to be 2002 MHz while above Speccy shows it as 4004 MHz. The third way of specifying it is to use the nVidia Virtual Memory Clock rate of 4x the base frequency which of course is 8 Gbits/second or 8008 MHz.
I hope this helps rather that confuses the issue
So my GTX 1060 at the overclock speed is 9.6 Gbits/second virtual speed
