AMD Radeon RX 6500 XT Could Be a “Disaster in the Making” for PCIe 3.0 Systems Due to Memory and Bandwidth Limitations

When the Radeon RX 6500 XT was released, AMD said it could handle 32GB of memory. However, new reports say that is not true and many users are getting poor performance on their systems due to this limitation. This means high-end GPUs from GTX 1060s up to 1080 Ti may also be affected by these limitations in the future which will change how graphics cards work if they cannot function properly with 4K resolutions or VR games like Destiny 2.,

The “pcie 3.0 vs 4.0 reddit” is a discussion on the performance of AMD’s RX 6500 XT graphics card, which could be a “disaster in the making” for PCIe 3.0 systems due to memory and bandwidth limitations.

New benchmarks published by TechSpot reveal that the AMD Radeon RX 6500 XT may disappoint gamers who want to use the graphics card in PCIe 3.0 mode.

While third-party benchmarks for the Radeon RX 6500 XT aren’t expected to be released until later this week, TechSpot has teased the performance of AMD’s new $200 budget option by testing its predecessor, the Radeon RX 5500 XT, under different PCIe bandwidth setups. If the cards are genuinely as comparable as TechSpot claims, owners of the Radeon RX 6500 XT may witness performance drops of up to 43% (1 percent min FPS) in games like Shadow of the Tomb Raider when the card is operated in PCIe 3.0 mode (x4, 4 GB/s vs. 8 GB/s).

According to the benchmarks, AMD could have partly averted this issue by matching the memory capacity of the Radeon RX 6500 XT to that of the prior model. In comparison to the 4 GB version, performance degradation appears to be much less in the Radeon RX 5500 XT with 8 GB of memory.

“[…] restricting the 4GB model to even PCIe 4.0 x4 severely lowered performance, implying that the 6500 XT might be constrained largely by the PCIe connection out of the box, which is rather alarming,” TechSpot concluded. “It also strongly implies that putting the 6500 XT on a system that only supports PCI Express 3.0 might be detrimental to performance in many cases.”

“At this time, we believe that all reviewers should be aware of this and test the 6500 XT in PCIe 3.0 mode.” You can easily flip between 3.0 and 4.0 in the BIOS, so there’s no need not to. Of course, AMD is hoping that reviewers will ignore this, and with the majority of them now testing on PCIe 4.0 systems, the 6500 XT may wind up seeming a lot better than it is for consumers.”

The Radeon RX 6500 XT is a graphics card with 1024 cores, 4 GB of memory, a boost speed of up to 2815 MHz, and a TBP of 107 watts that was announced earlier this month. According to AMD, the GPU provides up to 35 percent quicker gaming performance in 1080p at high settings than the competition’s products.
