Tom's Hardware Guide got its hands on an engineering sample of Intel's Core i7-4770K and published the very first preview of this upcoming Haswell-based chip! This quad-core eight-threaded chip has a 3.5GHz base clock, 3.9GHz boost, 8MB L3 cache, GT2 integrated graphics with a maximum clockspeed of 1.25GHz and a 84W TDP. You can check out the chip's performance over here, the conclusion is that the Core i7-4770K is approximately 7 to 13 percent faster than the Core i7-3770K in today’s threaded workloads.
Processors with Intel’s HD Graphics 4600 engine should offer notably better 3D performance than today’s HD Graphics 4000, though most enthusiasts purchasing unlocked K-series parts won’t even notice. An additional four execution units and a maximum dynamic frequency 100 MHz faster than Core i7-3770K are only good for incrementally-faster frame rates—but nothing that’ll replace discrete graphics (seems to be the conclusion we draw every generation, huh?). As before, desktop gamers will continue buying graphics cards.
The mobile space is where Intel’s efforts should become more apparent…and it has something for that market we anticipate will give AMD’s and Nvidia’s entry-level GPUs a serious run. CPUs with the GT3 graphics engine will only be available in BGA packaging, though.
