AMD has been talking about its upcoming Zen CPU architecture for quite a while and although we have seen some details, latest rumor suggest that these might have higher CPU clocks than we saw earlier.
According to a report
coming from AMD Polaris user from Anandtech forums, which had a good track when it comes to AMD rumors, a couple of recently spotted engineering samples of AMD Zen-based CPUs actually have higher clocks than expected.
The user suggest that AMD's 8-core Zen-based SKU will actually work at 3.15GHz base clock, with all-core Turbo set at 3.3GHz and max Turbo set at 3.6GHz. This is actually a big improvement considering earlier 8-core SKU under the same TDP envelope.
The second SKU, a 4-core with AMD's hyper-threading, has a 65W TDP and a base clock of 2.9GHz. The all-core Turbo is set at 3.1GHz while the max Turbo is set at 3.4GHz.
As you already know, AMD's Zen-base desktop CPUs and the new AM4 platform motherboards are expected early next year, with availability in February 2017.
