Asrock accidentally outs RX 5600 XT specs
ASRock briefly posted details for the 6GB AIB Challenger D version of the card. Tipster @TUM_APISAK shared a screenshot prior to the listing being taken down. The card is based on the 7nm Navi RDNA graphics architecture and sports the same core count as the Radeon RX 5700, with 2304 stream processors.
The main difference between the RX 5700 and the RX 5600 XT is in terms of the memory configuration. The RX 5700 has 8GB of 14GHz GDDR6 memory over a 256-bit memory bus while the RX 5600 XT features 6 GB of 12GHz GDDR6 memory over a 192-bit bus. At 288 GB/s, memory bandwidth on the 5600 XT is considerably lower than the 5700. The GPU core clock is also lower than the RX 5700.
At 1460 MHz, the "Game Clock" is among the lowest we've seen on a Navi part. We might be looking at a GTX 1070 Ti-esque scenario here. On that card, Nvidia deliberately dropped stock clocks to create a performance gap vis-a-vis the GTX 1080.
Considering that most Navi cards happily reach 1900-2000 MHz in-game, we wouldn't be surprised if overclocked RX 5600 XT variants deliver performance in the same ballpark as the RX 5700. The RX 5600 XT has not been officially confirmed yet, but we expect AMD will announce this card as early as next month.
