I have been testing the GTX 750 Ti video card with Adobe Premiere CC these last few weeks and this is how it compares to the GTX 650 Ti
1. Power Supply – The GTX 750 Ti only needs a 300 watt power supply, where the GTX 650 Ti needs a 400 watt power supply. So if you have an off the shelf computer such as HP or Dell, and the computer has a smaller power supply, which they usually do, you will be able to use this video card in those systems. Just make sure they have at least a 300 watt power supply.
2. Performance – The GTX 750 Ti and the GTX 650 Ti (not the boost version) performed almost identical.
Rendering the Premiere Timeline with our test files, the GTX 750 Ti took an average of 7.5 seconds and the GTX 650 Ti took and average of 8 seconds. Both tests I had the Premiere using the GPU.
Exporting to MPEG-2, the GTX 750 Ti took an average of 153 seconds and the GTX 650 Ti took an average of 156 seconds. Again, in these tests I had Premiere set to use the GPU.
As you can see there is not much of a difference between the two card performance wise. The big thing with the GTX 750 Ti, is it allows users that have a small power supply improve their editing performance without having to upgrade the power supply.
Bottom Line – If you have a GTX 650 Ti, there is really no reason to upgrade the video card to a GTX 750 Ti. If you are running an older video card, such as a GT 240, GT 440 or a GT 640, and you want better performance, then by all means upgrade to the GTX 750 Ti.
What about the GTX 750? Well there is only $20 difference between the GTX 750 and the GTX 750 Ti, so I only tested the GTX 750 Ti since it had more CUDA cores and the other specs were similar. Send the extra $20 and go for the GTX 750 Ti over the GTX 750.
