sapphire announced a curious launch, that of a low-end GPU like the Radeon RX6500XT but with double the memory compared to the reference model, that is to say 8 GB of GDDR6 at 18 Gbps. Although it offers more capacity, it is still tied to a 64 bitit therefore offers a low bandwidth of 144 GB/s. This way we have double the memory, but performance is the same.
The “curious” thing about the launch is that it’s a GPU that can’t move current games in Ultra qualitiesso 4 GB of memory was already more than enough, just an incentive to think about loading games with mods.
For the rest, it Radeon Sapphire RX 6500 XT is identical to the original model, so we have the same Navi 24 XT graphics chip with 1024 stream processors at a Turbo frequency of 2855MHz as well as two video outputs in the form of DisplayPort + HDMI. Although it is a new version, this GPU still uses the interface PCI Express 4.0 x4which implies a loss of performance if used on a platform with a PCIe 3.0 interface.
It should be remembered that this GPU, in Full HD resolution, renders like an NVIDIA GeForce GTX 1650 SUPERlosing performance at 2K, and already the bandwidth bottleneck is far more apparent at 4K, where it’s even lower than an older AMD Radeon RX 570.
