GPU Combine?possible?

[Leomarc]

HI Sir.

 

if its possible to combine  

Inno3d nVidia GeForece GT430 2GB and STRIX-GTX960-DC2OC-4GD5???

IF yes how?? using GT430 2gb as physx GPU??? any instruction? 

I have MSI B150m night Elf Motherboard

 

Thank YOU

Not sure if you could use that as a physx gpu but even if you could it would definitely not be worth it.

Define "combine". If you mean having both working on the same PC, yes. Your software has to support using the 2 GPUs at the same time, though.

It's possible, but don't even bother. It'll actually decrease performance rather than improve it.

Sure, you can use the less powerful card for PhysX. However, it will likely give you lower frame rates than if you just used the gtx960 alone. For more information, see this older LTT video.

ahhh ok... it will give lower frame rates?

what is the use of using physx if it cause lower frame rates?

 

if going to combine this 2 card??

There really is no use in cases were the PhisX card is a severely less powerful card.

A dedicated physX card can increase the fps by the frame or two if it's a powerful card in and of itself, but the 960 is so much better it would cream the 430's performance even with all the other stuff it has to render. 

You can't combine cards, not how you want to at least, not in games. Sorry.

ahhhh ok guys.... thank you so much. hehe.. cause im thinking to used my old card. hehehehe thank you guys.

Not necessarily. Considering the performance of a GTX 960 there should be a performance boost using a GT430 as a PhysX card. Its similar to using a GTX 650ti OC 2GB as a PhysX card for my GTX 970. Despite having the 650ti on the motherboard's PCIe x2 slot (x16 length, only in x4 with the middle 2 PCIe slots disabled-I really don't like using mATX motherboards) I saw a significant boost in performance.

Loading PhysX on a dedicated card, offloads 100% of the Physx load from the main GPU to the PhysX card. As such, there is a limit to how weak your second GPU can be before the main workload needs to wait for the PhysX workload. This means that performance gains (or loss) depends on which game you are playing, and at what settings you are playing.

 

A GT 430 has less than 10% the Cuda cores of the 960, and has a bit bellow 25% of the memory bandwidth. Very rough math, this means that the PhysX workload needs to be about 10% of the total workload. Sure, you can find a game out there where the 430 gives a boost at the right settings. But generally, the 430 will slow down the 960.

The GT 430's cores are also significantly slower, in terms of clock speed and IPC. Running a dedicated card for PhysX is almost a moot point. Sure, there is a wide array of games that support PhysX, but not many of them support GPU accelerated PhysX due to NVidia locking down the technology.
