"We can safely assume that on AMD's current 65 nm process, we will
not see the Phenom go past 2.5 GHz. Going to 2.6 GHz and above would simply
result in a product with an insanely high TDP and very stiff requirements
for motherboard manufacturers to support in terms of power delivery. In the
desktop market, this is simply unacceptable. While AMD uses a system of
constant improvement with their process technology, we are simply nearing
the end of what AMD can do with its 65 nm process."
