Intel Core i7-6850K Pictured and Benchmarked, ~10% Higher IPC Than Haswell
Photos of the Intel’s upcoming six-core Core i7-6850K have just made their way to the web thanks to an enthusiast by the name “Maintenance Bot,” over at OCN forums. The user also benchmarked the new 14nm Broadwell-E CPU against the older 22nm Haswell-E i7-5820K which was launched back in 2014.
The leak reveals the i7-6850K has the same pin layout as the i7-5820K, but has some very different power circuitry towards the bottom of the chip. Also, the new 6850K has a thinner PCB than Haswell-E CPUs, which raises concerns about it having the same bending issue that Intel Skylake CPUs have had in the past with certain CPU coolers.
Moving on to the benchmarking part, both 6850K and 5820K were put through a few handy tests with test-bench comprising of the ASRock X99 Extreme3 motherboard (BIOS: P3.30), 16 GB of quad-channel DDR4-2133 memory, and a single GeForce GTX 980 Ti graphics card.
The user overclocked both chips to 4.2 GHz, but suggested the 6850K could go even more higher.
In Cinebench R15, the new Broadwell-E CPU on average yielded a 10% higher IPC than Haswell. Although IPS gains for the i7-6850K are not groundbreaking, yet they could lead to better performance in a number of apps, including gaming. For single-core performance, the chip was put through SuperPi 32M, where the 6850K completed the test in 8m 27.874s, with the 5820K pulling behind by just over 11 seconds.
Worth noting, these results are from an early Engineering sample so final results might be a bit better.
Spec-wise, the the i7-6850K is based on the 14 nm “Broadwell-E” silicon, and features six cores, HyperThreading enabling 12 logical CPUs, 15 MB of L3 cache, and a nominal clock speed of 3.60 GHz. The CPU is also is pin-compatible with existing socket LGA2011v3 motherboards.
