NVIDIA RTX 3080 PCIe 3.0 vs. PCIe 4.0 x16 Benchmarks (& Intel vs. AMD for 3080 Discussion)
Показать описание
The NVIDIA RTX 3080 GPU uses PCIe Gen4, and so we have another opportunity to benchmark PCIe 3.0 vs. 4.0, using an AMD X570 platform for benchmarks as to whether PCIe gen matters.
CORRECTION: Slide at 05:10 for Quake II RTX should read "R9 3900XT and X570 Crosshair VIII Hero," not 10700K. Sorry about that copy/paste error.
PCIe generation testing has always been a hot topic for GPU launches, but this time, it's about PCIe 3 vs. 4. We've most commonly talked about PCIe 3.0 x16 vs. PCIe 3.0 x8, and as Ryzen has matured, that has presented opportunities for Gen4 testing -- except only the 5700XT could leverage it, and so it didn't particularly matter. That's not to say the 5700 XT wasn't good, but just that it was unable to leverage the additional bandwidth in any meaningful way. Our previous testing with Titan RTX cards also showed limited gains, and so we're revisiting this storyline today with our NVIDIA RTX 3080 GPU (the Gigabyte Eagle also makes a brief feature). This tests PCIe generational bandwidth for gaming and for workstation workloads.
