25% Performance Improvement of 7TH Gen. Intel® Core i7 Processors on MSI Gaming Notebooks.


Posted on January 16 2017

Last week Intel launched their latest 7th Gen Core i7 processors platform, the most popular models are 7700HQ standard CPU and 7820HK overclock CPU, the CPU clock add 200MHz more than previous version, and the architecture enhanced a bit, that makes the CPU performance boost more than 10% faster on different usages.
In some usage such as VR experience, you will see the bigger performance gap, because the CPU performance might be the bottleneck when we play heavy loading interaction games or multiple usage of calculations with AI predict programs.

VR Experience Performance Boost Up to 25% with same GTX 1070

VR was the hottest and boost topics on content development or gaming experience in 2016, so the VR benchmark is an important index to show how good is the VR performance of a gaming laptop is, the FPS rate is the most important thing, because when I use VR gears like HTC VIVE or Oculus Rift, I need to make sure that each eye’s glass could have stable performance to keep over 90FPS, otherwise I will feel dizzy very soon.

When I use last platform of Core i7 6700HQ and GeForce® GTX 1070 graphics, I will simply get the VRMark performance around 7100pts, but when I use the latest GT73VR with 7820HK and still same GTX 1070 graphics, I could get 8854pts, that makes the VR experience boost more than 23% in this VRMark test of “Orange Room” item.
If I change the CPU become 7700HQ, I could still get 7996 score, this result makes the VR experience on 7700HQ platform over 12.6% faster than 6700HQ with same GTX 1070 graphics at basic clock, the CPU performance did boost a lot on VR experience enhancement.

The 7700HQ and GTX1070 on VRMark test is 7996 score, that brings more than 12.6% faster VR score than 6700HQ and GTX 1070 graphics at 7100 score.

CPU arithmetic and OpenGL test is 10% faster

Most usage of the CPU performance is about arithmetic, like data calculation, simulation, image design processing, video transcoding, and 3D rendering, the 7th Gen Core i7 7700HQ also improve around 10% faster on this type of calculation, When I test CineBench R15, the CPU benchmark score is 735~739cb score, if runs on Core i7 6700HQ, the score is 674cb, so i7 7700HQ is around 10% faster than 6700HQ on the arithmetic and 3D rendering usage performance enhancement.

The Core i7 7700HQ got 735cb score on CineBench R15 test.

The Core i7 6700HQ got 674cb score on CineBench R15 test.


Core i7 7700HQ of Video Transcoding Test Up to 11% Faster

The FHD and 4K video transcoding getting more popular in recent years, so I also looking forward to see what Core i7 7700HQ could improve on this part. I used “X264 FHD Benchmark” tool to test the  performance gap between Core i7 7700HQ and 6700HQ.

Let’s take a look on the result, the 7700HQ with this video transcoding benchmark comes out 25.2fps, which is faster than Core i7 6700HQ test result of 22.7fps. 7700HQ shows 11% faster on the video transcoding benchmark than 6700HQ, so the 7th Gen. Core i7 platform did improve the FHD/4K video transcoding performance and could reduce the time for video editing.

Intel® Core i7 7700HQ got 25.2fps on X264 FHD Benchmark test.

Intel® Core i7 6700HQ got 22.70fps on X264 FHD Benchmark test.


Conclusion on the 7th Gen Core i7 Performance Improvement

With these 3 simple but useful benchmark tests, we could realized that the latest Intel® 7th Gen Core i7 platform are capable to improve most of the software and usage around 10% between 7700HQ and 6700HQ, if I use 7820HK OC to 4GHz, the performance boost rocks to 21%~25% higher than 6700HQ, It’s really worth to buy the latest Core i7 platform for your 1st gaming laptops or refresh your platform over 2 years, and if you got enough budget, 7820HK with GTX 1070 graphics will be my first choice on GT73VR model, and GS series or GE series with 7700HQ and GTX 1060 will also be great choice if you like slim or with ODD for different usages.
