New leaks just seem to keep on coming. After we talked about the latest 7th generation Kaby Lake Core i3, a hardware sample Intel’s forthcoming i7-7700K made its way into the hands of review editors over at Tom’s Hardware.
The Intel Core i7-7700K received by Tom’s Hardware may or may not be a retail version of the processor, however, the benchmarks are extremely interesting. The Core i7 is an unlocked quad-core chip and rocks eight threads and has a factory clock of 4.2 GHz.
According to the test conducted by them, the Core i7 has a very high speed but consumes a large amount of power and is quite hot after overclocking. The processor was able to get to 4.8 GHz at 1.30 but gets hot very quickly.
This is what they had to say about the testing.
“The overclocking experiment even required a 15 degree C room temperature, which is something most readers won’t be able to accomplish,” wrote Thomas Soderstrom of Tom’s Hardware. “Liquid might help, but since the cooler’s heatpipes were barely warm to the touch, there’s a possibility that 4.8 GHZ may be the limit of this sample while using any ambient-temperature cooling solution.”
So it seems that while the new Core i7 will be able to hit serious speeds, you’ll need to have serious cooling solutions in order to achieve them. The Kaby Lake chip however, beats its sky lake counterpart.
In mixed workload tests, the i7-7700K narrowly edged out the Core i7-6700K in all benchmarks other than a video conversion test. It’s a narrow lead, but it points to some of the performance gains the latest round of 7th-generation Kaby Lake quad-core processors can offer.
