Will then discuss the differences between them to help you find out, which you should get in your laptop first let's note: the similarities between these two chips, both have four CPU cores with a threads, are based on a 14 nanometer manufacturing process. They also have the same 91 watt TDP, with eight megabytes of cash available and both CPUs support up to 64 gigabytes of RAM with two 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 6700 K is clocked slightly lower at 4.0 gigahertz and can turbo up to 4.2 gigahertz, while the newer 7700 K is clocked at 4.2, gigahertz again server up to 4 point 5 gigahertz. It also overclocked slightly better how much of a performance difference does this make practically to test this I've run some CPU specific benchmarks on the 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 16 gigabytes of ddr4 memory available. The laptop with the 6700 K is running the memory at 2000, 133 megahertz. What the 7700 k's memory is running at 2400 megahertz. Apart from this small difference, the graphics cards are also different, but that shouldn't matter is we're. Not comparing any games here so the other main difference is, of course the CPUs, which is what we're testing here.

So hopefully you can see. The laptops are mostly similar in Cinebench the cpu score for the 6700 K was 836, while the 7700 K received 894. So a little improvement but an improvement. Nonetheless, in the past bucks CPU benchmark the 6700 K received a CPU score of eleven thousand one hundred and eight. Interestingly, the 7700 K received a score of ten thousand 667, which is actually slightly lower. I ran this test. A few times and got similar results, the new, a cabe you like CPU came behind, but all the skylake CPU in terms of overall score on this test consistently. In my 6700 hqv 7700 HQ CPU video. We actually had the same result where the skylake CPU, big, julik, so I'm, not too sure what's being tested in this test, is actually better on all the chip or more likely, the particular benchmark. Hasn'T properly been optimized for cable, a chips. Despite this, if we actually look at the number for the individual tests, in most cases, the 7700 K is actually slightly ahead. So it could also be that this particular benchmark generates the final score in a strange manner in Geekbench for the 6700 cake of 5080. One for single core and 16000 177 for multi, core 7700 cake or 5265 for the single core score and 16000 347 for the multi core score. This was another interesting test. Although the single core performance in the 7700 K is higher, as expected, the multi core performance result was much closer again.

This depends greatly on what the test actually does behind the scenes. However, I found it interesting that the results seem to favor single core performance over multi core, the 7 zip benchmark was also very close. I ran up the 10 passes with the dictionary size of 32 megabytes. The 6700 K got a total rating of 20 4548 minutes, while the 7700 K could a total rating of 25 thousand and forty four nips. So the 7700 K was only slightly faster, a compression tasks here and then use handbrake to encode a 500 megabyte mp4 video file that I recorded from 1080p to 720p. The 6700 K completed the job at an average speed of forty three point: seven frames per second, while the 7700 K complained, it encoding the same file at forty five point: three frames per second, so the 7700 K was only slightly faster in the encoding test. I didn't test temperatures here, as the cooling solutions between both laptops were actually quite different, so I didn't feel comfortable, comparing the two, as I didn't feel that it was very fair. In general, however, the K V wake CPU was slightly warmer as expected, based on its higher clock speeds, assuming that your particular laptop could keep your temperatures in check, and you could also attempt to perform overclocking. However, as this would increase, power draw and heat, it, doesn't really seem as appealing in the laptop form factor when compared against overclocking in the desktop CPU.

And if you saw my recent 7700 H, cuber 7700 K video, where I did do overclocking, I got less than a 4 performance increase throughout all these tests, which i think is hardly worth it in a laptop anyway. So, based on all these tests, the 7700 K appears to only be a very small incremental upgrade on average, with all of these combined, the 7700 K performed approximately two point: one percent better on stock clock speeds when compared against the 6700 K kind of pathetic. I figured that this would be the case after watching a bunch of 6700 K and 7700 K benchmark reviews previously, when K V Lake was released. However, I wanted to test these CPUs in a laptop rather than desktop, to get an idea of laptop performance and find out, if they're, possibly worth considering over other chips, such as the HQ series. Overall, I found the results a bit disappointing, as the 6700 K was released in q3 of 2015, while the 7700 K came out in q1 of 2017. So, despite being quite a lot new, I it's not actually that much better. Hopefully, the recent release of Verizon CPU starts to change. This trend in weak performance increases that we've seen from Intel recently, I didn't notice any practical difference between using the two laptops with either of these CPUs day to day. So if you're looking at a new laptop, the 6700 K is definitely still fine, as the newer version only offers extremely small performance improvements, at least in the workloads demonstrated here by all means.

If your new laptop has a 7700 K CPU and you can afford it, then go for it, but if you're looking at one that has a 6700 K and it's definitely still a good competitor and might be cheaper now, due to it being considered last generation. If the prices are pretty similar, then I'd suggest going for the newer 7700 K. Otherwise, you'll need to determine if the extra cost is worth it based on. The small performance increases that we've measured in our tests here, if you're already running at 6700 K there's. Basically, no incentive to upgrade to the next generation unless you need to buy a new laptop anyway, for other reasons will require cable, eight specific features such as 4k decoding at the hardware level, 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 with either of these CPUs. I hope this video is help. You see the real world differences in performance between these two CPUs be sure to leave a comment on the video and, let me know which of these CPUs. You pick and leave a like on the video.
