When using a PCIe 3.0 x4 slot with a Radeon 5600 XT GPU, the available bandwidth may influence performance, particularly at higher resolutions and refresh rates. This setup is paired with a 1440p 240Hz ultrawide monitor, which demands significant data throughput due to its additional pixel count.
The 4 Gbps bandwidth of PCIe 3.0 x4 raises questions about its capability to sustain frame rates such as 80 fps in triple-monitor setups or 120 fps in dual configurations, as well as its compatibility with supersampling techniques. While a GPU performance spreadsheet suggests the 5600 XT can achieve 260 fps at 1440p, it remains unclear whether this accounts for frame generation or the extra demands of ultrawide displays. Understanding how these factors interact would help clarify the slot’s limitations.
Interesting point about PCIe 3.0 x4 bandwidth potentially struggling with high refresh rates on ultrawide 1440p – I noticed similar stuttering when running my 5600 XT on PCIe 3.0 x4 in racing sims with triple monitors. That spreadsheet claiming 260 fps at 1440p seems optimistic considering the extra pixels from supersampling and ultrawide formats. Has anyone actually tested frame times with this specific configuration?
Thanks for sharing your real-world experience with racing sims on triple monitors—that stuttering you noticed aligns perfectly with the bandwidth limitations we discussed. For actual frame time data with this setup, I’d suggest checking Hardware Unboxed or Gamers Nexus on YouTube, as they often test specific PCIe configurations. Let me know if those benchmarks match what you’re seeing, and I’m curious whether adjusting settings like texture quality helped in your case!
