Intel is all set to launch Kaby Lake processor on January 5, 2017. The tech enthusiasts are indeed waiting for the performance results of the new development from Intel. Intel Core i7-7700K, being the top most processor in the Kaby Lake processor family is compared with the current best processor of Intel-Skylake Core i7-6700K.
According to WCCftech, it is reported that already two publications are made on the performance tests made between the Intel Core i7-7700K and Core i7-6700K processor by Tomshardware and Nova Tech reports. Now, a report by Expreview gives clear information on the new KabyLake processor.
Overview on Intel Core i7-7700K Kaby Lake processor.
The Intel Core i7-7700K processor used in the test is the fastest Core i7 chip in the Kaby Lake lineup, featuring 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 i7-6700K Skylake processor, the flagship chip of the 6th generation family is used which is the best available chipset from Intel.
Test Set-up
It is reported that the tests were conducted on a Intel Z270 series motherboard, featuring a GeForce GTX 1070, G.SKILL 8 GB DDR4 (2133 MHz), a Sandisk Extreme Pro 240 GB SSD and the Prolimatech Mehahelms cooler.
Test 1: Stock Performance test
It is reported that Core i7-7700K is up to 7.40% faster on average in single-threaded and up to 8.88% faster on average in multi-threaded performance compared to the Core i7-6700K. The results were reportedly achieved by keeping both CPUs at stock settings and were tested through 11 different CPU tests
Test 2: Clock-To-Clock 4 GHz Performance Tests
It is reported that the Intel Core i7-7700K and Core i7-6700K processors were clocked at 4.0 GHz and tested through all 11 CPU benchmarks as seen in the earlier test. The results were reported to be surprising, as Core i7-7700K is 0.86% slower in single-threaded and 0.02% slower in multi-threaded tests.
Test 3: Power Consumption and Temperature
Core i7-7700K is reported to have 10W higher power consumption than Core i7-6700K and the default voltage is also increased to 1.2V. The default voltage in the Core i7-6700K is 1.176V. The higher power consumption in the 7700K is due to increase in clock speeds.
Because of higher clock speeds, Core i7-7700 is reported with a temperature of 73.6C at full load with 4.4 GHz and on the other hand, the Core i7-6700K stays at 67.2C at full load at 4.0 GHz.
