The first performance benchmarks of Intel’s Core i7-7700K Kaby Lake CPU have been leaked over at Chinese forums. The benchmarks showcase the performance of Intel’s 7th generation, flagship Core processor which is going to launch on 5th January at CES 2017 (Consumer Electronic Show).
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 improvement comes solely from the clock speed bump but is it enough to compensate for the new processor lineup? Let’s find out.
The Intel Core i7-7700K processor is the fastest Core i7 chip in the Kaby Lake lineup. This chip features a quad core, multi-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.
The Core i7-7700K testing was performed on a Z170 platform. It comprised of a MSI Z170A Gaming Pro board, GALAXY HOF DDR4 series memory clocked at 4133 MHz. The setup also featured a MSI GeForce GTX 1070 DUKE edition graphics card, DeepCool Big Frost Tower Extreme cooler and a 256 GB M.2 SSD from Samsung.
By using the latest firmware update provided by MSI, they board booted up, supporting the Kaby Lake chip just fine. The CPU-Z shot shows the exact same specifications for the processor as listed above.
First up, we have that famous Chinese software which is known for installing a ton of spamware inside your PC and you can’t even control it. The chip scored 377,544 points in the test. In Fritz Chess benchmark, the chip is scoring 17,049 kilo nodes per second. Cinebench R15 CPU performance is rated at 913 points.
AIDA64 numbers are pretty good and were tested with the native memory speed of 2133 MHz. The benchmark reported scores of 30188 MB/s Reads, 31137 MB/s Writes and 27000 MB/s Copy speeds. Finally, we have 3DMark 11 where the chip scored 8467 points on the extreme preset using the GTX 1070 card. During all tests, CPU temperature hovered around the 60C mark at the reference clock speeds. Overclockers should be eyeing beefier cooling that should go along fine with a K-Series chip.
Overclock benchmarks were performed at a clock speed of 5.0 GHz. The memory speeds were also pumped up to their max XMP profile which is 4133 MHz. This would result in some huge gains in memory intensive tests. In Cinebench R15, the chip scored 1089 points while Fritz Chess benchmark reported a score of 19891 Kilo Nodes per second. Both tests were performed with the native memory clocks since the overclock didn’t hold up as well as expected.
The clock speed for the memory was bumped to 3100 MHz in 3DMark 11 which is the maximum this board can support with stability. Performance numbers were bumped to 8664 points on the extreme
