Pro GPU vs Consumer

Ilija

Does lets say AMD firepro W4100 and Nvidia Quadro K620 both around 150$ outperform consumer GPUs like GTX 950 or R7 370 both around 150$ a in Photoshop. I know that in CAD and SolidWorks Pro GPU are better, saw it with my own eyes, but didn't test it on Photoshop.

By the way if you look just numbers consumer GPU are better, but with these applications they really are not. (different algorithms and architecture... consumer is build for speed FPS in games, pro is build for precision in programs).

Thanks for comments

Most likely there won't be much difference.

The GPU is identical between the consumer and pro variants - in the case of the W4100 for instance, it's the same as a Radeon HD 7700. The boards that the chip is on is different though - they have more tolerance built in. There is absolutely no margin for error in pro boards - gamers will put up with the very occasional crash if a board gets too hot or power is glitchy. So pro boards have more capacitors on them for power smoothing for example.

Most of the difference is in the driver, for 2D work the two will likely be very similar.
For 3D, the pro cards will possibly be slower but more accurate. The gaming driver will be written purely for frame rate and a faster but slightly less accurate algorithm may be used if available.
Things like twitching lines (where a point is rendered halfway between two pixels, and rounding errors can make it appear to flicker) are the sort of things the pro driver writer cares about.
