How powerful must be a dedicated PhysX card ?

with 4 comments

Linus Tech Tips website has performed several benchmarks to find out if low-end dedicated PhysX cards are still valuable in systems with high-end graphics cards, using Mafia 2 benchmark.

8600 GTS GPU is clearly bottlenecking the whole system, resulting in lower fps than even a GTX 580, despite the fact that if single NVIDIA GPU is used in Mafia II, PhysX effects are partially running on CPU.

Cards Performance
GTX 580 + 8600 GTS 30.3 fps
GTX 580 49.7 fps
GTX 580 + GTX 580 57.5 fps
GTX 580 + GTX 550 Ti 56.6 fps
GTX 580 + GTX 560 Ti 55.3 fps

In conclusion, in case if you want to pair a dedicated PhysX card with GTX 580-class GPU, find a decent one – GTX 550 or “even something a little bit lower-end”, as author of this video recommends.

  1. The biggest issue I can see here is that of comparing with the 8600GTS, wouldnt it be more realistic to compare using something a little bit more modern and less low end(eg 9800GT or a 200 series card).
    It would be useful to help show if when I upgrade my motherboard I should get something which is SLI capable…

  2. Just like David said, this comparison is worthless and does not tell anything at all.

    What ppl would really like to know is if someone upgrade their 260 or 280 GTX to 480 or 580 GTX is it worth to keep their old cards or it’s more smart to sell them on ebay.

    Who in the world upgrades from 8600GTS to a GTX580?

  4. I have actually always found Linus to be very informative vs. having to do extensive testing on your own. The debate would be something like a 9800GT vs. GTS 450 for the Physx sweet spot!
