On Intel Z270 motherboard
There have already been plenty of leaks from other websites regarding Intel’s upcoming Core i7-7700K Kaby Lake CPU. Today we can finally show some of our own tests. A few weeks ago we have started testing all the new motherboards in order to our motherboard charts as well as our Content Creation articles updated.
Our tests confirm what we’ve already seen with all the other leaks. At standard clock speeds, the Core i7-7700K is on average 10% faster in multi-threaded applications than the Core i7-6700K. If we set both CPUs to 4.2 GHz then the average difference is less than 5%. Nevertheless in single-threaded applications with same clock speed, like for instance in “Black Hole”, we can see that the Core i7-7700K is only 1% quicker than the Core i7-6700K.
In addition we also ran a couple of benchmarks with a retail CPU pushed to 4.8 GHz at 1.35 volts. So far our first CPUs looks pretty bad in terms of overclocking headroom but still we managed to get some interesting scores. The benchmarks have been conducted on a Z270 motherboard with 2x4GB DDR4 memory. With a Fractal Design Kelvin S24 CPU cooler we have reached 80°C quite quickly running Cinebench R15, while hitting 1055 points.
At the moment we haven't done any 3D tests but we are sure that the difference between Kaby Lake and Skylake will be tiny once again. During the next days you can expect more benchmarks and reviews on Kaby Lake CPUs as well as Z270 motherboards.
