Intel’s Kaby Lake Core i7-7700K Review

We are very excited to get an early sample of Intel ‘s future 7th generation of Kaby Lake background 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 technical analysis of the Kaby Lake architecture, but alternatively a head on comparisons of Kaby Lake and Skylake ( its harbinger ) processor .
Build on a 14 nanometer and with the same LGA 1151 socket as Skylake, the Kaby Lake central processing unit seems to be good an optimize version of Skylake with factory overclocking or it is something all together a different fib. Let ‘s find out below .
inaugural the latest three generation of Intel ‘s top of the channel background 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 newly Intel ‘s Kaby Lake Core i7-7700K Quad-Core processor .


We will be comparing Intel Core i7-6700K against Intel Core i7-7700K central processing unit 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 count on the Kaby lake CPU, Intel have redesigned the IHS ( Integrated Heat Spreader ) of the central processing unit, increasing the top reach area of IHS by small divide .

On bottom reach diggings side, we have the like phone number of by-pass capacitors and claim pads layout as Skylake. But we can distinctly 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 control panel with Intel Z170 chipset for Skylake ( GIGABYTE Z170X Gaming G1 ) and for Kaby Lake we are using a modern motherboard ( GIGABYTE Z270X Gaming 5 ) with Intel ‘s newly chipset, the Intel Z270 chipset .
For tied comparison I have overclocked the Skylake CPU up to 4.5GHz to match the soap congress of racial equality 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

Thermal Performance

To check thermal handling of both CPUs we used two different approach. First we used AIO cool ( Cooler Master Nepton 240M ) on both CPUs. Second we cooled down both CPUs up to -34C using Single stage Phase Changer. immediately we put load on both CPUs by started Intel Extreme Tuning Utility CPU stress test for 10 minutes and plot the follow graph registering change in temperature
AIO cooling

Phase Changer cooling


From above temperature testing we noticed that with AIO cooling solution the new Kaby Lake showed poor people thermal performance than the older Skylake generation, but extreme cooling showed a slender different narrative, there is little less increase in temperature of i7-7700K CPU than that of i7-6700K CPU under a 10 minutes stress test. The new TIM on i7-7700K appears to work little better under sub-zero temperature or it seems that the TIM on i7-6700K has aged due to time .
Intel have merely merely changed the IHS design in Kaby Lake, the inner thermal compound is still icky as that of the 6th generation of processors .

Power Consumption

There was not a major baron consumption remainder noticed between i7-6700K and i7-7700K CPU .

Pros

• Higher stock clock speed.
• Newer 4000+ MHz of XMP profiles for DDR4 memory
• Z270 chipset shows slight increase in storage performance.

Cons

• Still crappy internal Thermal interface material (TIM)
• Not much of a performance difference against Skylake CPU
• Just increase of 4 extra PCIe Express Lanes.

Conclusion

For most enthusiasts out there the raw Core i7-7700K CPU is nothing great to like about. With rise in the clock speed the Core i7-7700K offers a detectable operation hike at stock clock against its harbinger genesis Core i7-6700K CPU, making it the fastest background processor every produced by Intel.

With precisely a BIOS update one can use the raw Kaby Lake CPU on existing Z170 platform. And Core i7-7700K could be an choice for a new personal computer build and people who are looking for an upgrade from older generation CPUs .
It is very deplorable to see that Intel is even using a inadequate quality home Thermal interface substantial with the new Core i7-7700K Kaby Lake CPU. Intel can justify that the apply TIM keeps the silicon under its thermal limitations according to its datasheet, but still for an end drug user indicate a better thermal intensify will help benefit in overall organization ‘s thermal management for a retentive discharge, which is distinctly being neglected by Intel .
Thanks .
