Whats with 32 and 64 bit CPUs and relation with GPU ?

Akhil anil · Aug 23, 2015

My pc is 32bit. The graphics card i'm planning to buy - (Forsa NVIDIA GeForce with CUDA GT620 2GB DDR3 64 BIT PCI EXP w/HDMI Graphics Card ) - is 64 bit. Will it work on my pc ? Motherboard has PCI e 1x16 slot.

Are you sure? Some websites say it won't... I don't wanna waste money , you know.. who wants?

post your full system build.

Your PC being 32-bit means that your operating system is 32-bit. Some games like Dragon Age Inquisition require a 64 bit OS to run. Your card will not work with games that have this limitation, but that's due to your OS, not your graphics card.

The 64-bit of your card is the memory interface. Without getting too technical, this can rage all the way up to 512-bit in current graphics cards, and is only an indirect measurement of how much memory bandwidth the graphics card has. This has nothing to do with running on a 32-bit or 64-bit OS.

The only limitation for your card not working that I can think of, is if you have an extremely old or non-windows operating system, that your card doesn't have drivers for.

So will a 64 bit graphic card will work on my 32bit pc?

My GPU is 512 bit, this doesn't mean my 64 bit OS can't run it. Yes you can run that GPU.

Even though pcie suppose to be backward compatible.
With such an old motherboard, there are high chance that it will not work with any new pcie gpu.
