AMD is showing better than 4670K performance with an engineering sample clocked at 2.8ghz with a 3.2ghz boost clock. DDR4 doesn't provide nearly as much benefit as some seem to believe. The benefit of DDR4 only shows in applications that are bandwidth intensive, which isn't really the case with gaming, unless you're using an iGPU. If you're using a dedicated graphics card, the benefit of DDR4 over DDR3 is minimal. Also, the benefit of "more cores" in gaming is dependent on the game engine being used. Not all game engines are "optimized" for more cores. That's why we see i3 processors holding their own against i5s and i7s. Most games benefit more from IPC and frequency increases than they do core count increases.
