ASRock (via VideoCardz) now confirms in its specifications that the Radeons RX 6500 XT will have four PCIe 4.0 x4 interface lines as well as modern SSDs. This was to be expected due to the eight lines on the Radeon RX 6600 XT.
–
It should be noted here that the predecessor in the form of Radeon RX 5500 XT offers eight lines of the same interface, ie PCIe 4.0. In this case, it is really no longer possible to argue that the goal was to create a less attractive card for miners, because if something is absolutely uninteresting and insignificant for miners, then it is precisely the throughput of the interface between the card and the processor.
Ani z detailed card specifications on the AMD website we will not know about this limitation, which can be quite significant. Not everyone will have a report that already supports PCIe 4.0, so in that case it will only end up on PCIe 3.0 and the resulting throughput will be only 4 GB / s, ie a quarter compared to full PCIe 3.0 and an eighth compared to PCIe 4.0 with 16 lines. And that could affect the resulting performance. –
We also have something else they came up with in 3DCenter, namely the lack of AV1 decoding acceleration and then this Radeon does not even support encoding in JH.264 / 4K and H.265, which is already confirmed by AMD specifications.
