In the offer of professional graphics cards of the company AMD we have two news Radeony Pro W7800 a W7900. Both are built on the new RDNA 3 architecture, which should bring significantly higher performance. AMD, for example, talks about a 1.5-fold increase in performance for the W7900 model, and the memory capacity has also increased by half, which now amounts to 48 GB. There is also a 50% increase in ray-tracing, new AI instructions double the performance in AI tasks. Both novelties have a chiplet design with a 5nm GCD (Graphic Compute Die) and a 6nm MCD (Memory Cache Die). The cards can also boast of the DisplayPort 2.1 interface, which brings 3 times higher throughput and can thus handle output with 50 MPx on each of the ports (that’s 1.5 times more than 8K). There are three classic ports and one in the mini version. There is also an AV1 video encoding and decoding engine.
