Nvidia RTX 3080: PCIe 4.0 vs 3.0 scaling analysis

3DMark Fire Strike is a showcase DirectX 11 benchmark designed for today’s high-performance gaming PCs. It is our [FutureMark’s] most ambitious and technical benchmark ever, featuring real-time graphics rendered with detail and complexity far beyond what is found in other benchmarks and games today.

First of all, we ran 3DMark's PCI Express feature test, and the results confirm that we have double the bandwidth available through PCIe 4.0 vs 3.0.

So far, there's not much to report with these synthetic tests. The Intel system outperforms the 3900 XT PCIe 4.0 system by 5% in Fire Strike, while remaining 1% faster in the rest of the benchmarks. We see no effective difference between the 3900XT Gen4 and Gen3 results.
