The first performance benchmarks of AMD's Radeon RX 5600 XT 6 GB graphics card have leaked out by Videocardz. The upcoming graphics card would part of the third series in the RX 5000 line which is powered by AMD's Navi graphics architecture.

The AMD Radeon RX 5600 XT has seen various specifications leaks so far. The card is expected to offer a new GPU which is neither Navi 10 or Navi 14. It could be a new SKU configured for the RX 5600 XT and would have a different naming scheme than the GPUs featured on the RX 5700 and the RX 5500 series cards. In terms of core count, the stream processors would fall somewhere in between the RX 5500 XT's 1408 and RX 5700's 2304 SPs. We can get 1920-2048 stream processors but that is just speculation at this point.
