PCIe Gen5 boosts 1440p FPS
Real‑world tests show PCIe Gen5 can lift 1440p Very High frame rates by about 10% — roughly 99 fps to 109 fps with DLSS Balanced in the cited benchmark — making a measurable difference for high‑fps 1440p builds. That echoes prior Doom: TDA results and gives builders a tangible reason to consider Gen5 boards for GPU‑limited setups. (x.com)
Tom’s Hardware measured an RTX 5060 Ti across 27 titles at 1440p and reported the GPU averaged 59.4 fps on a PCIe 5.0 platform versus 55.82 fps on PCIe 4.0, a gap the outlet described as “up to 10%” in some tests. (tomshardware.com) (tomshardware.com) GamersNexus’ RTX 5090 PCIe scaling tests found much smaller deltas for a flagship Blackwell card, reporting roughly 1–4% average loss when the interface was bandwidth‑restricted and only about a 1% difference between PCIe 5.0 x16 and PCIe 4.0 x16 in their Ryzen 7 9800X3D bench. (gamersnexus.net) (gamersnexus.net) TechPowerUp’s RTX 5090 PCI‑Express scaling review likewise showed the high‑end 50‑series card is largely insensitive to Gen5 bandwidth at typical gaming resolutions, noting single‑digit percent shifts and calling out workloads and link width (x16 vs x8) as the bigger variables. (techpowerup.com) (techpowerup.com) Independent YouTube comparisons that swap an RTX 5070 between PCIe 3.0/4.0/5.0 across titles such as Cyberpunk 2077, Alan Wake 2 and Counter‑Strike 2 demonstrate per‑game variability — some games show measurable Gen5 gains while many do not, depending on RT, upscaling, and frame‑generation settings. (youtube.com) (youtube.com) DOOM: The Dark Ages benchmarking from outlets including TechPowerUp and community reports flagged the title as sensitive to GPU link bandwidth in certain configurations, with users urging checks of GPU bus interface (x16/Gen4/Gen5) after seeing large FPS swings on RTX 50XX hardware. (techpowerup.com) (techpowerup.com) Taken together, published tests show Gen5’s biggest, measurable impact so far on midrange or lower‑VRAM cards and on specific games that stream or generate lots of GPU‑side data, while top‑end GPUs like the RTX 5090 more often show single‑digit differences; reviewers recommend per‑game, per‑GPU testing rather than assuming a universal uplift.
