Running a Ryzen 3700x on a Strix B450-F board with PCIE 3.0.  But just upgraded to a 7900 xtx.  Is there a way to run a test to see if i'm hitting a bottleneck with the PCIE gen?

 

Thank you!

Thank you!

your bottleneck will be the CPU by a lot before  PCIE 3.0 vs 4.0 matters. If you dont intend to upgrade to a 5800x3D then you will be missing out some performance.

It's a very small difference that you wouldn't notice at this time.. your CPU would be more of a potential bottleneck.

as others have said, you’ve got a moderate CPU bottleneck already, pcie 3.0 bottleneck isn’t really there on the 7900xtx

PCIE Gen 4 is mainly going to be useful for fast NVME storage, once developed. GPU's won't ever need it in the foreseeable future.

But just upgraded

So you bought it?

 

Well, time to save up for the 5800X3D, because thats sure as hell a pretty big gap on anything but 4K.
