AMD will release Ryzen 6000U / H Rembrandt (Yellow Carp) APUs next year, which will finally have an RDNA2 GPU, according to numerous leaks. In addition, these APUs are credited with the Zen 3+ processor architecture, although why only them.
Be that as it may, fresh data suggests that the new APUs, unfortunately, will not have a third-level cache, that is, they will not have Infinity Cache, like current video cards with RDNA2. Previously, there were similar rumors, but at least at the moment there is no mention of this in the update of the Linux kernel yet.
As we saw on the example of Radeon RX 6000 video cards, Infinity Cache allows you to significantly increase performance with not the widest memory bus. Perhaps hybrid processors simply do not need such a solution.
