RTX 5090 - CPU Bottlenecks, PCIe Scaling, Benchmarks & More

It turns out the RTX 5090 is being held back. By how much? Let's talk about that. Because the RTX 5090 is supposed to be the fastest GPU in 2025 at 4K and 1440p, with and without ray tracing. But when we examined its gaming benchmarks, temperatures and power consumption something stood out. So we went deep to measure potential CPU bottlenecks, PCIe scaling and more.

NOTE: Some charts list X670E. Motherboard should be X870E.
