Let's compare the performance of the new Core i7 4770K with that of its predecessor, the 3770K. In the table below we put all of the benchmark results of both CPUs, along with the difference.
Overall the performance gain is 23.8 percent, but that doesn't tell us very much. The results of the 3D benchmarks are impressive, as the Core i7 4770K is more than 50 percent faster. It's clear that Intel has improved its integrated graphics, and this is just the GT2 version. It will be interesting to see what GT3 has in store.
In the CPU benchmarks the average gain is 10.6 percent. Do note that this includes benchmarks with Quick Sync, OpenCL and AES-NI. When we exclude those, we end up with an average of 7.2 percent. And to be honest, for a new architecture, that's a little bit on the meagre side.
