Advanced Micro Devices (AMD) announced "AMD FX-9590" and "AMD FX-9370, World's first commercial 5GHz and 4.7GHz CPU for PC's.
The eight-core FX-9590 will debut in destop PC's this summer. It probably won't come cheap and it consume amount of power at 220 Watts.
At E3, AMD demonstrated why is at the core of gaming," Bernd Lienhard said "The new FX 5GHz processor is an emphatic performance statement to the most demanding gamers seeking ultra-high resolution experiences, including AMD Eyefinity technology. This is another proud innovation for AMD in delivering the world’s first commercially available 5 GHz processor.”
As these are enthusiast chips, overclocking will also be a significant factor - the top Ivy Bridge and Haswell (Intel i7 4000 series) can both overclock about 15% over stock speeds ; it's unknown whether there will be similar overclocking headroom left in AMDs latest. If these chips can hit 5.7GHz, and if doing so does not raise power draw to utterly intolerable levels, these chips won't be disadvantaged - however that is a very big if.
In the end, it's hard to see Richland making a big change to the market this year. AMD's big chance should come when it releases a new architecture, known as Kaveri, planned to start manufacturing late this year, with the first systems in early 2014. This introduces an updated CPU core architecture known as "Steamroller," which should offer an improvement in raw CPU horsepower, and what AMD is calling heterogeneous Uniform Memory Access (hUMA), which should allow the CPU and GPU units to work together more closely.
