Very signficant, if true:
"Perhaps the biggest announcement is that AMD has increased the maximum cores per CCX from 8 to 16".
There's a good reason for gamers to buy >8 CPU cores, as there won't be a latency penalty, performance should scale much more uniformly.
They need this to compete with Intel well, imo.
It's one of the things I considered as essential to improve on Zen 4. Essential for their sales + profits to increase also, so I'm sure this is something they are likely to want for Zen5.
Also, if the rumoured 16 core CCX is not used in desktop CPUs, then it's a huge waste of the design.
But MLID leak, so who knows. Trust, but verify*.
