Some observations:
1. Usually, the chips with fewer cores clock faster. Here the opposite appears to be true. I suppose it's a way to encourage people to buy the higher end chip. Unless the lower end models can be overclocked easily. Time will tell.
2. No Ryzen 3 chips were announced. I'm hoping they'll come sooner rather than later. Not everyone can afford a $299 CPU. The trouble is, most gamers don't need more than 4-6 cores, so releasing Zen 3 Ryzen 3's early will no doubt hurt higher margin Ryzen 5 sales.
3. It would appear AMD has finally won the single core crown from Intel (at least according to the announced single core Cinebench score). Well done AMD.
The Cinebench score seems remarkable given that Zen 3 tops out at 4.9GHz vs Intel's 5.3GHz.
However, Intel's hitting those frequencies at 14nm whilst AMD's now on 7nm. I wonder what's stopping AMD clocking faster? And when (if?) Intel hits 7nm, there's a good chance they'll be on top again.
Nevertheless, it's a great time to be building some kick ass machines :-)
