Our
Photoshop Benchmark includes a large number of tasks that don't utilize the GPU, but there are five tasks in our benchmark that should show a benefit to having a more powerful GPU. These results are used to calculate the "GPU Score" portion of our benchmark which does a great job at showing the relative performance difference between each card in a more general sense.
As you might expect if you have read any of our previous articles looking at GPU performance in Photoshop, there is not a massive difference between each card. However, for the GPU accelerated tasks there is a clear performance advantage when using NVIDIA GeForce cards. While pricing varies widely based on numerous factors like sales or the popularity of bitcoin mining, in general you can think of the following rough price parity:
- AMD Radeon RX 580 8GB -> NVIDIA GeForce GTX 1060 6GB
- AMD Radeon Vega 56 8GB -> NVIDIA GeForce GTX 1070 Ti 8GB
- AMD Radeon Vega 64 8GB -> NVIDIA GeForce GTX 1080 8GB
Using these as comparison points, we see roughly a 6% performance advantage with NVIDIA GeForce over the AMD Radeon cards. This is often less than a second or two difference, but as we mentioned earlier you also need to consider the reliability, availability, power draw, noise level, etc. - most of which are also in favor of NVIDIA at the moment. in addition, keep in mind that this is testing overclocked Vega cards against stock GeForce cards.
Something else we want to specifically call out is that since we ran our full Photoshop Benchmark, we have results from a number of tasks that are not supposed to utilize the GPU in any significant way. What was interesting is that for one task (Adaptive Wide Angle) we saw much lower performance with the AMD Radeon cards even compared to the Intel HD 630 integrated graphics:
We don't know why the AMD cards did so poorly in this test or why the Vega cards did worse than the RX 580, but we re-ran the test multiple times and the result was very consistent. As far as we could find, this task is not supposed to utilize the GPU which is backed up by the fact that the Intel HD 630 integrated graphics was just a hair slower than any of the NVIDIA GeForce GTX cards. At the moment, we are willing to chalk this up to some driver bug, but we wanted to point it out since it was something we didn't expect to see.
Conclusion
Photoshop is relatively light in the way of GPU acceleration, but based on our benchmark testing we saw a very clear (albeit small) advantage to using NVIDIA GeForce cards over AMD Radeon in Photoshop. Choosing the right GPU for Photoshop isn't nearly as important as choosing the right CPU or having enough RAM, but at similar price points you should see roughly ~6% higher performance in
GPU accelerated tasks by using NVIDIA GeForce - not to mention the lower power draw which means less heat and noise with those NVIDIA cards.
We are often asked how AMD's Radeon Vega video cards compare to their NVIDIA GeForce counterparts. Photoshop rarely benefits from having a powerful GPU, but there is still a measurable difference between these two brands of cards.
