Reports online suggest that some i7-7700Ks can get to 5GHz and beyond. The absolute maximum I could get from our current test rig setup, which admittedly is limited by RAM that maxes out at 2,666MHz, was 4,944MHz. Since I wrote this original review, I’ve tinkered with some manual overclocking to see how far I could push it beyond 4.9GHz. This wasn’t in-depth tweaking, but simply using Asus’ super-simple EZ Tuning Wizard, which found an easy 4.9GHz overclock in a few mouse clicks.Ī combination of the wizard and Corsair’s decent H100i liquid-cooling saw the chip pull off this overclock with relative ease it managed significantly better scores in both Cinebench multi- and single-core tests, equating to a 7.9% performance increase on an 8.2% clock speed increase at a peak temperature of 76 oC. I also ran some quick overclocks on the 7700K. Again, I’ll have to investigate whether this is down to the slightly different test system in use this time around. At these speeds, the 7700K managed a score that was 3.1% higher than that of its predecessor. It will cost you, but if you run intense multimedia operations such as rendering, the reduction in processing time will be significant.įor an apples-to-apples comparison, I also clocked the 7700K to the same speeds as the 6700K, limiting it to 4.2GHz. Owners of the fourth-generation (Haswell refresh) Intel Core i7-4790K will be heartened to see that if they upgrade now, they’ll net an extra 23.4% of performance. For my full review I’ll revisit the 6700K on our current test system and see if the results correlate. That’s good news if correct, although because the systems aren’t identical there is the possibility of our current test rig helping things along a little. Keeping in mind that the maximum speed of the 7700K is only around 7% higher than the 6700K, the new chip looks to be grabbing extra performance as a result of other efficiency gains, not just from its higher clock speed. All four cores were able to sustain the maximum 4.5GHz Turbo Boost speed for the entire benchmark. The graphs above show that, at stock speeds, the Core i7-7700K can outperform the i7-6700K by 8.2% in single-core loads and 9% in multi-core loads. The Cinebench benchmarks results in two scores: one for single-core performance and another for multi-core performance. I ran the test without any GPU assistance, so the scores achieved represent raw processor performance that most accurately reflects the differences between Skylake and Kaby Lake. The best way of obtaining a quick and easy performance measurement is by running Maxon Cinebench – a benchmark that tests a system by rendering a highly detailed 3D scene.

I benchmarked the processor in our regular test rig. ![]() Performance, gaming and overclocking Review.
