Exactly as the title says. Long story short, I recently upgraded from an RX 5700 to a 6700 XT, and I'm pretty sure my MOBO's 3.0 PCI-E slots are whats keeping its benchmark performance only as good as my 5700, rather than better.
My build, for frame of reference:
CPU: Ryzen 7 3700X
GPU: RX 6700XT
RAM: 8GBx4 DDR4-3200 CL16 (G.Skill Trident Z Royal to be specific)
MOBO: MSI B450 TOMAHAWK
SSD: Samsung SSD 970 EVO 1TB NVMe(boot drive), 2x Samsung SSD 860 EVO 1TB SATA
PSU: EVGA G3 750W 80+ Gold
As I said, I'm reasonably certain it's my MOBO and the 3.0 ports causing some degree of bottlenecking- but I'll admit, I'm savvy with hardware but not savvy. I wouldn't know where to begin looking at my options beyond going onto PC-Partpicker and filtering by compatibility. And I'm also not particularly savvy in doing much more troubleshooting than updating the drivers, so I'm open to other options. Can't say I'd be fond of replacing my MOBO to begin with, they're just a chore.
So tl;dr version: Upgraded GPU, pretty sure my MOBO is bottlenecking it, looking for advice on what I can do to optimize my build.
EDIT: Including a comparison of the benchmarks on my 5700 vs 6700XT
