Particularly interesting is the 16 GB GDDR6 memory, which is divided into 10 GB and 6 GB blocks and is connected at different speeds.

The fact that the AMD APU is manufactured in 7nm has been known for a long time, new are the details of the GPU and the memory of Microsoft’s upcoming console. A total of 16 GB is installed, of which 10 GB is connected at 60 GB/s and 6 GB at 336 GB/s. This is based on a processor with 8 cores and 3.8 GHz (3.66 GHz with SMT), which is based on the Zen 2 architecture.
