Intel’s Kaby Lake Core i7-7700K Review

I7-7700K.jpg



We are very excited to get an early sample of Intel’s next 7th generation of Kaby Lake desktop processor. The Intel Core I7-7700K to be exact and prepared this review/comparison to show what new Intel is to offer with Kaby lake.


This review is not about an in-depth technological analysis of the Kaby Lake architecture, but instead a head on comparisons of Kaby Lake and Skylake (its predecessor) processor.


Build on a 14 nanometer and with the same LGA 1151 socket as Skylake, the Kaby Lake processor seems to be just an optimized version of Skylake with factory overclocking or it is something all together a different story. Let’s find out below.


First the latest three generation of Intel’s top of the line desktop end processors side by side.
From left to right, first we have Intel Core i7-6700K the Skylake processor, than there is the Intel Broadwell-E Core i7-6950X processor a 10-cores 20- threads beast and last on the right hand side we have the new Intel’s Kaby Lake Core i7-7700K Quad-Core processor.

We will be comparing Intel Core i7-6700K against Intel Core i7-7700K cpu below.




Features

  • Processor Number : i7-7700K
  • Lithography : 14 nm
  • No. of Cores : 4
  • No. of Threads : 8
  • Processor Base Frequency : 4.20 GHz
  • Max Turbo Frequency : 4.50 GHz
  • Cache : 8 MB SmartCache
  • Socket : LGA 1151



Package
Taking a close look on the Kaby lake CPU, Intel have redesigned the IHS(Integrated Heat Spreader) of the processor, increasing the top contact area of IHS by small fraction .

On bottom contact pad side, we have the same number of by-pass capacitors and exact pads layout as Skylake. But we can clearly see that Intel have removed some of the test point pads from Kaby Lake it seems as all of the testing have already conduct during Skylake.

Testing
For testing both Skylake and Kaby Lake CPU, we are using board with Intel Z170 chipset for Skylake (GIGABYTE Z170X Gaming G1) and for Kaby Lake we are using a new motherboard (GIGABYTE Z270X Gaming 5) with Intel’s new chipset, the Intel Z270 chipset.


For even comparison I have overclocked the Skylake CPU up to 4.5GHz to match the max core speed of Kaby lake CPU.


The Intel’s new Z270 chipset offers following plus points against the older Z170 chipset.

  • New Intel Optane Technology, which promising the elimination of system bottleneck which requires fast and better storage memory. read more about Intel Optane Technology.
  • Intel Rapid Storage Technology Version 15 against older version 14
  • Increase in Maximum High Speed I/O Lanes ( HSIO) from 26 to 30 lanes
  • Increase in Maximum PCIe Express 3.0 Lanes from 20 to 24 lanes

No integrated graphics bench? That's one thing they are improving with the new iterations. But looking at benches from other sites it is worse than Broadwell. That is a massive fail.
