Another day and we have another full review of the Core i7-7700K Kaby Lake processor from Expreview. The latest review pits the 7700K against the 6700K in several benchmarks.

Intel Core i7-7700K and Core i7-6700K Tested Against Each Other - Top Kaby Lake and Skylake Put To The Test

Intel's Kaby Lake processors are scheduled for launch on 5th January 2017. The launch is less than a month away and we have already seen two independent performance reviews published. The latest one by Expreview will be the third performance test published for the Core i7-7700K processor. The other two tests were posted by Tomshardware and Nova Tech.

The Core i7-7700K is the top brass of the Kaby Lake processor family. It is based on the existing 14nm process node which has seen improvements due to a matured manufacturing technique. Intel calls the optimized node 14nm+ (Plus). These process improvements result in better clock gains under the same TDP headroom as Skylake.

Kaby Lake gets most of its architectural hierarchy from Skylake and next to no gains in the IPC department. The performance improvements come solely from the clock speed bump. The processor has been compared against the Core i7-6700K Skylake processor which is the flagship chip of the 6th generation family. The tests from the Chinese site are interesting since they also provide clock-to-clock comparisons which we will see in a bit.

Intel Core i7-7700K – The Fastest Core i7 Kaby Lake Processor:

The Intel Core i7-7700K processor is the fastest Core i7 chip in the Kaby Lake lineup. This chip features a quad core, hyper-threaded design. The chip is based on the latest 14nm Plus process node which delivers improved efficiency and performance on the existing 14nm FinFET technology. The clock speeds are rated 4.2 GHz base and 4.5 GHz boost. The processor packs 8 MB of L3 cache and has a TDP of 91W. The Core i7-7700K CPU will retail at $349 US.

There are several SKUsin the Kaby Lake lineup, ranging from dual cores to quad cores. Benchmarks of the Core i5-7600K and the Core i3-7350K have already been covered. The Core i5 chip manages to offer up to 10% performance increase over the Core i5-6600K while the Core i3-7350K manages to tackle Quad core CPUs. The specifications and expected prices for Kaby Lake desktop processors (Kaby Lake-S) are listedbelow:
