Nvidia RTX 3080: PCIe 4.0 vs 3.0 scaling analysis

Here we revisit Shadow of the Tomb Raider, this time with ray tracing effects set to Ultra.

At 1080p in Shadow of the Tomb Raider, we do see some benefit to PCIe 4.0, as the 3900XT results with Gen4 are 3% higher than the same CPU running PCIe 3.0. However, that still only puts performance on par with our Intel system, which remains the case at 1440p and 4K resolutions.
