That's about what I hope they'll do, a 10% increase in frequency while using no more power than Zen+. 10% would get us to 4.7-4.8 GHz. Another thing that will be interesting to see is what will be the minimum configuration of Zen2. It seems like yields would have to be poor to cut down Ryzen 3000 to 4c/8t. Could we see the lowest Zen2 sku#s at 6c/6t?
