The notable feature of the specification in this leak is that the card has 6GB of RAM, which feels like a somewhat strange amount. This may or may not be set in stone for all models, after all some of the 5500 cards have 4GB, others 8GB, so it feels like 6GB for the RX 5600 XT might not be the only version. According to the data the clock speed on the GPU is around the 1600MHz mark. The performance data makes it about a third faster than an 8GB RX 5500 XT.
While we always take rumours with a pinch of salt it does feel relatively uncontroversial for the card that slots into the price point between the RX 5700 XT and the RX 5500 XT to have a specification and performance level that also fit in that spot. No alarms and no surprises.
With CES not far away it seems logical that any new graphics card about to drop will be announced there.
