Intel Core i7-7700K Benchmarks Leaked, Overclocks To 4.9GHz

The Intel Core i7-7700K benchmarks have leaked out, showcasing the performance of the company’s fastest 7th generation Kaby Lake processor.

The flagship Core i7-7700K CPU is based on the latest 14nm Plus FinFET process which delivers better clock gains and power efficiency over existing Skylake chips. The quad-core, multi-threaded chip features clock speeds of 4.2GHz base and 4.5GHz boost. It packs 8 MB of L3 cache and is rated at 91W TDP.

Intel Core i7-7700K Benchmarks With Stock and OC Speeds

The Intel The Core i7-7700K performance testing was performed on a MSI Z170A Gaming Pro board. The chip scored 17,049 kilo nodes per second in Fritz Chess benchmark, while Cinebench R15 CPU performance is rated at 913 points. In 3DMark 11, the chip hit 8467 points on the extreme preset using the GTX 1070 card.


The Core i7-7700K benchmarks reported scores of 30188 MB/s Reads, 31137 MB/s Writes and 27000 MB/s Copy speeds, with the native memory speed of 2133 MHz. During all tests, CPU temps varied around the 60C mark at the reference clock speeds.

Let’s move to the Core i7-7700K benchmarks with 5.0GHz OC. The memory speeds were pushed to 4133 MHz, bringing in some impressive memory intensive gains.


In Cinebench R15, the chip managed to hit 1089 points while Fritz Chess score comes out to be 19891 Kilo Nodes per second. Both tests were performed with the native memory clocks; however the memory speed did bump to to 3100 MHz in 3DMark 11 with the chip scoring 8664 points on the extreme preset.

Core i7-7700K Overclocked to 4.9GHz at 1.29V

Apart from benchmarks, a Facebook user Luning Duan has posted screenshots of the Core i7-7700K processor overclocked to 4.9GHz easily at just 1.26V. He shared CPU-Z and AIDA64 screen captures showing the chip’s overclocked settings as well as Prime95 CPU stress test.


The first attempt results in the Core i7-7700K hitting 4797.65MHz using a x48 multiplier and 1.296V. This however results in one of the cores flirting with a 100C temperature.

In his second attempt, Duan manages to overclock the chip to 4,901.18MHz with a x49 multiplier and 1.264V. This time, one of the cores hovered around the 90C mark, while other three mostly stayed in the low to mid 70C range.

We suspect this to be on air cooling, though Duan doesn’t say. Either way, there should be some headroom for overclockers to play with.

Intel is set to launch its entire Kaby Lake desktop lineup on 5th January at CES 2017. As for the pricing, the flagship Core i7-7700K CPU will retail at $349 US.
