  • Hey guys, Jarrod here and today were going to compare the Intel Skylake 6700HQ CPU against

  • the newer Kabylake 7700HQ. Well run some benchmarks to see how they perform, and discuss

  • the differences between them to help you find out which you should get.

  • First let’s note the similarities between these two chips. Both have 4 CPU cores with

  • 8 threads, are based on a 14nm manufacturing process, they also have the same 45W TDP with

  • 6MB of cache available. Both CPUs support up to 64GB of RAM with 2 memory channels,

  • and provide 16 PCI Express lanes.

  • That’s where the majority of important similarities ends, so how do they differ? The main difference

  • is that the older 6700HQ is clocked slightly lower, at 2.6GHz and can turbo up to 3.5GHz,

  • while the newer 7700HQ is clocked at 2.8GHz and can turbo up to 3.8GHz. How much of a

  • performance difference does this make practically? To test this weve run some CPU specific

  • benchmarks on two different laptops with these processors to find out.

  • Both laptops are running Windows 10 with all available updates installed on an SSD, and

  • have 16GB of DDR4 RAM @ 2400MHz, apart from the differences in graphics cards, the main

  • difference is the CPUs which is what were testing, so the laptops are pretty simialr

  • otherwise.

  • In Cinebench the CPU score for the 6700HQ was 691, while the 7700HQ received 740, so

  • only a small improvement but an improvement nonetheless.

  • In the PassMark CPU benchmark the 6700HQ got a CPU score of 8,973, interestingly the 7700HQ

  • got a score of 8,820 which is actually slightly lower. I ran this test multiple times with

  • the same result, the newer CPU came behind the older CPU in terms of overall score on

  • this test consistently. Despite this if we actually look at the numbers for each individual

  • test, in almost all cases the 7700HQ comes out slightly in front, so it seems like the

  • way this particular benchmark generates the final overall score is a bit strange.

  • In GeekBench 4 the 6700HQ got 4,334 for single core, and 13,066 for multi-core. The 7700HQ

  • got 4,402 for the single core score, and 12,293 for the multicore score. This was another

  • interesting test, although the single core performance of the 7700HQ is higher as expected,

  • the multicore performance was slightly behind in this specific test. Again this depends

  • on what the test actually does behind the scenes, however in this instance the 7700HQ

  • was slightly slower in the multicore test which I found quite interesting.

  • The 7-Zip benchmark was run for 10 passes with a dictionary size of 32mb. The 6700HQ

  • got a total rating of 19,121MIPS, while the 7700HQ got a total rating of 19,602MIPS, so

  • the 7700HQ was slightly faster at compression tasks here, though barely.

  • I then used Handbrake to encode a 500mb MP4 video file that I recorded from 1080p to 720p.

  • The 6700HQ completed the job at an average speed of 35.084 FPS, while the 7700HQ completed

  • encoding the same file at 37.928 FPS. The 7700HQ was only slightly faster in the encoding

  • test.

  • In most of the tests, the 7700HQ was ahead of the 6700HQ, however I still found these

  • results quite interesting. These two CPU’s also have inbuilt graphics, and while I don’t

  • expect anyone to buy these CPUs for their inbuilt graphics, it’s worth comparing them

  • to see if there are any differences. I’m going to leave this for a future video though,

  • as my test results are actually showing the older 530 graphics in the 6700HQ outperforming

  • the newer 630 graphics in the 7700HQ in every test that I throw at it, so some more investigation

  • is required there first.

  • Based on these tests the 7700HQ appears to only be a very small incremental upgrade,

  • which I figured would be the case after watching a bunch of 6700K and 7700K benchmark reviews,

  • however I wanted to test these laptop chips as I didn’t see anyone else doing it and

  • I was curious. It’s a bit disappointing too, as the 6700HQ was released in Q3 of 2015

  • while the 7700HQ came out in Q1 of 2017, so despite being quite a lot newer it’s not

  • that much better.

  • I didn’t notice any practical difference between using the two laptops with either

  • of these CPUs, so if youre looking at a new laptop the 6700HQ is definitely still

  • fine, as the newer version only offers extremely small performance improvements, at least in

  • the workloads that were tested here. By all means if your new laptop has a 7700HQ CPU,

  • go for it, but if youre looking at one that has a 6700HQ then it’s definitely still

  • a good competitor and might be cheaper now due to it being last generation. If the prices

  • are similar then I’d suggest going for the newer 7700HQ, otherwise youll need to determine

  • if the extra cost is worth it based on the small performance increased that weve measured

  • in our tests here.

  • If youre already running a 6700HQ there’s basically no incentive to upgrade to the next

  • generation unless you need to buy a new laptop anyway for other reasons. Unless something

  • drastically changes within the CPU area in the near future, you probably won’t need

  • to upgrade your laptop in terms of CPU power for quite some time.

  • So what did you guys think about the differences in performance between the 6700HQ and 7700HQ

  • CPUs from Intel? Personally I’d like to see something better from Intel next generation,

  • but I’m not expecting much at the moment. Who knows maybe AMD will finally shake up

  • the scene with Ryzen. Be sure to let me know your thoughts down in the comments, and leave

  • a like on the video if you found it useful. Thanks for watching, and don’t forget to
