Cant wait for Kaby Lake 7700K launch on 5 Jan 2017, only 66 days left.
It did not mattered when people always said Kaby Lake IPC is not improved since Sky Lake and they said the same thing every year since Ivy Bridge in games benchmarks. It is because old games had not been properly optimised for new and future CPUs so you needed to waited for new games that are properly optimised for Kaby Lake and you will see massive performance increase compared to old CPUs.

Take a look at Elder Scroll V: Skyrim for example, the game was released on 11 November 2011 5 years ago was been properly optimised for old CPUs Conroe, Westmere and Nehalem as well as new Sandy Bridge CPUs at the time.
5 years passed since Ivy Bridge, Haswell, Broadwell, Sky Lake and now Kaby Lake, we saw very little improvement in performance compared to Sandy Bridge 2600K because the game was not properly optimised for future CPUs.
But things get very interesting when Bethesda released Skyrim remastered version that was been properly optimised on latest CPUs and likely upcoming Kaby Lake CPUs too.
Just WOW you can see massive 55% performance boost between original and remastered version for Sky Lake 6700 CPU.

The original version saw Sky Lake 6700 had 12% performance increase over Sandy Bridge 2600K, after properly optimised in remastered version saw Sky Lake 6700 had huge 28% performance increase over Sandy Bridge 2600K. So Kaby Lake will see around 10% performance increase over Sky Lake in games.
Wish games developers noticed this and decided they should follow Bethesda footstep to remastered all old games that properly optimised for modern CPUs and GPUs that will see massive performance boost.
