High clock speeds are not the same thing as high wattage, they aren't even really related, or very closely associated. We have no idea what the power usage of these processors will be. They could even end up being more efficient than previous processors, doing more instructions in a shorter period of time then powering back down to idle sooner on the same workload. Yes people might decide to throw more work at them as a result, but that's not the CPU's fault, that's a people problem not a hardware problem.
P=C*V^2^*f
Power increases linearly with frequency.
IF all else remains constant. Which it doesn't, and isn't.
Do you have any idea how significant of an improvement it is for AMD to bring their process node to this level? All the variables going to be different here, and it's too early to tell what that means until we see the actual silicon.
Correct. I never stated anything different. I was replying to the statement that “high clock speeds and high wattage are not related” when clearly frequency affects the power output in a linear fashion. Of course changing a manufacturing process is going to likely change the capacitance but the biggest savings in thermal has been the decrease in voltage as the process have shrunk.
I don’t get the downvotes though. I posted an accurate, relevant formula to the discussion and stated a factual statement.
