Will Gen 3 PCIE bottleneck a 7600 while gaming. It only has an 8 PCIE lane interface.

Unfortunately the RX 7600, RTX 4060 and RTX 4060 TI only have 8 PCIE lanes. This means at Gen 3 speeds they have a bandwidth of 8GB/s which is half of Gen 4 speeds. There is a possibility that Gen 3 will bottleneck these GPU's. In this video we will test the RX 7600.

cpu: Ryzen 9 7900x
cpu cooler: Thermalright frozen prism 360mm aio
gpu: Asus Dual OC RX 7600
ram : G.SKILL Trident Z5 RGB Series 32GB (2x16GB) DDR5 6400MHz CL32
storage: Western Digital WD_BLACK SN770 M.2 2280 2TB
psu: CORSAIR RMx Shift Series RM1000x
case: corsair 7000D

I’d be interested to see a more CPU intensive game like BG3 in act three. I could see the bandwidth between the GPU and CPU being an issue and that situation.

Im getting really low fps especially fps dropping constantly in valorant. Before Rx 7600 which i just got it yesterday I had gtx 1660 ti and i got 200fps to 300fps never dropping below 200fps but with rx 7600 I et 150 to 250fps with alot of fps drops up to 80 fps. I have a PCIE 3.0 motherboard and Ryzen 5 5500. Ive seen alot saying thats the problem but based on benchmarks it proves otherwise, tho i just cant get it to work at 100% ( my cpu also around 50% usage). Have i missed something to tweak or in the BIOS? (I also just fresh installed win 11)
