Compatible

Hi, just wondering if my asrock b460m motherboard would be compatible with the amd Rx 6600xt Gpu.

 

Thanks.

In general any modern motherboard is compatible with any PCIe graphics card. PCIe is backwards and forwards compatible.

 

Since the b460m only has PCIe 3.0, the GPU would run in backwards compatible mode (i.e. also PCIe 3.0). Since it only has 8 lanes, rather than 16, you'd be somewhat bandwidth constrained compared to a board that had PCIe 4.0 x8. In most cases that shouldn't matter though, at least for this GPU.

So If i get this gpu it will performe normally? I wouldnt get like -20fps

From what I've seen, it doesn't suffer too much when limited to PCIe 3.0.

 

The story is different with the RX 6500 XT for example, which is limited to a x4 connection and loses a good chunk of performance on PCIe 3.0, so for that one you'd definitely want a motherboard/CPU with PCIe 4.0.
