The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

The Intel G4560 is one of the first Pentium processors to feature Hyper-threading. This means that although the G4560 only has two physical processing cores, it is able to process four threads in parallel by sharing resources between the physical cores. This typically results in a 50% performance improvement over two physical cores alone. Comparing performance between the lowest spec Kaby Lake i3 7100 and the Pentium G4560 shows that in terms of both performance and specs, very little separates them (even virtualization technology VT-d is present on the Pentium). The Pentium does lack AVX 2.0 (Advanced Vector Instructions) and it trails the i3 7100 by 400 MHz (10%) but there is no longer a clear divide between Pentiums and Core i3s. Intel have achieved an almost continuous distribution of performance levels for each price point from the cheapest Pentium to the top end i7-7700K[Jan '17 CPUPro]
