The original post was to evaluate the performance of desktops versus laptops for 4k 264 and 265 video editing
This was posted by JL_JL on a different thread and is the heart of the subject::
TonyL/others, the simple little test was suggested to Eugene as he was questioning the idea, how his CPU could be limiting the capability of his GTX960 GPU considering his CPU was only operating in the ~30% range during encoding. I simply suggested a 4K profile as that’s Eugene’s typical interest and it does present a significant challenge of elapsed wall time to encode.
Maybe this set of instructions will suffice:
1) Put 10 of the PD default media “Kite Surfing.wmv” into the timeline. If you don’t load PD default media modify your PD pref to load. Pref > Project.
2) In the PD “Produce” tab, set “Profile name” as H.265, MKV and default preset profile, HEVC 4K 4096 x 2160/30p (37Mbps)
3) In the PD “Produce” tab, set “Fast video rendering technology:” to enable “Hardware video encoder”
4) Start the Produce operation
5) Monitor GPU load of the GTX960 with free utility TechPowerUp GPU-Z, under sensor tab, the “Video Engine Load” (
https://www.techpowerup.com/downloads/SysInfo/GPU-Z/ )
6) Monitor CPU and RAM usage during the encode processes with default windows Task Manager
7) Items 5 and 6 are usually rather stable throughout the encoding process for this simple test provided if you don’t have significant “other” stuff running
When produce operation is complete, the “Time elapsed:” and “Produced” files size from the PD window.
Repeate above steps with item 2) of: H.264, MP4, MPEG-4 4K 4096 x 2160/30p (50Mbps)
Sample pic of results attached. From my experience what one will see is a reasonable separation of GTX960 capability, probably on the order of 50% difference or so for the exact same task on different computers.

This too is from an other thread and contains my test results:
The encoding time test is a GREAT idea Jeff!! No guess work here and everybody can do the same exact test.
Using 10 ea kite surfing as suggested ,total length 1.42
Encoding 4K MKV 265 HEVC, 37 Mb, 30FPS. Encoding time 2.02 min, GPU video engine 80%, CPU 35% 6.3 GB memory used.Video 460MB
Play back MPC64, GPU 26%, CPU 6%.
-------------
Encoding to 4K 264 MP4, 49Mb, 30FPS encoding time 2.02 min, GPU video engine 43%, CPU 39%,4.6 GB memory, Video 626MB.
Play back MPC64, GPU 29%, CPU 6%
I was surprised to see the 960 GPU video engine running at 80% during HEVC encoding, not much room left there.
Encoding is almost in real time, video only no transitions etc.
My jaws are still on the floor when I look at these numbers in regard to HEVC. W/O the 960 it would have taken at least 1Hour 30 minutes to encode the same 1.42 min in PD14 HPQ mode.
Encoded video looks as good as the original.
Looking forward to see other forum members numbers.
ESPECIALLY from LAPTOP owners

PepsiMan posted very interesting results but spread over mant pages, could you please combine the results on one page?
TonyL
I noticed that your computer is the same as mine with the exception of the GPU. Could you please run Jeff's test and post the results? You have everything neded for that. Took me less than 1/2 hr to do.
Also the data file is not visible.
