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. .

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.
