According to Neowin, AMD’s silence about this low-cost graphics card seems to stem from many limitations on that product. For example, the card only comes with 4 GB of video memory. Additionally, the official RTX 6500 XT specs on AMD’s website reveal the new low-cost graphics card lacks AV1 decoding and H.265/HEVC encoding – something higher-end Navi GPUs have. .
Radeon RX 6500 XT has a lot of limitations that users need to know
The lack of AV1 support on the new Navi 23 RX 6500 XT and RX 6400 essentially makes these GPUs pretty mundane, looking like a modern home theater (HTPC) system since AV1 content is pretty common these days. Out.
As for gaming capabilities, AMD’s low-cost graphics cards are also quite limited. German website 3DCenter discovered on ASRock’s site that the Radeon RX 6500 XT is limited to only 4 channels (x4) of PCIe bandwidth.
While this new graphics card supports PCIe 4.0, anyone using it on a PCIe 3.0 motherboard will essentially be limited to half the throughput, i.e. 32 GT/s or about 4GB/s. In a VRAM intensive game like DOOM Eternal, low PCIe bandwidth can lead to huge performance drops.
