Intel Skylake i7-6700K Benchmarks Leaked

Another batch of Skylake benchmarks have leaked out a little under a month before the expected launch. This time we have the Intel i7-6700K on an ECS Z170-Claymore paired with 16GB of 2133Mhz DRR4, 128GB SSD and a GTX970. For comparison an i7-4790K on an MSI Z97A Gaming 6 with 8GB of 1600Mhz DDR3 with the same GPU and SSD. Both systems used the stock Intel heatsink with the copper core.

PCMark 8, 3DMark, Cinebench R15, and Sandra 2015 were tested with the 6700K coming first in the images with the 4790K following. As you can see Skylake trades blows with Haswell in PCMark 8, only managing to pull ahead significantly in the Home test. In the two Firestrike tests, Haswell manages to pull ahead but Skylake manages wins in Cloud Gate and Sky Diver.

Cinebench R15 shows a win for Skylake with a notable improvement in multicore efficiency. OpenGL shows a big jump due to the improved iGPU on Skylake. For Sandra 2015, the red line is Haswell and blue for Skylake. The two trade blows in the arithmetic test, but Skylake pulls ahead in multimedia, cryptography and memory bandwidth. The final two are expected given additional instruction support for cryptography and DDR4 with Skylake.

As we pretty much expected, Skylake is a minor bump in terms of IPC gains, being able to pull ahead of Haswell despite being clocked lower. One can’t forget that the extra bandwidth offered by DDR4 might be giving a boost to Skylake so those with 2133Mhz DDR3  Haswell might see fewer gains. Drivers for the motherboard are still in beta, but not too much is likely to change in that field. These benchmarks serve to confirm the general trend shown by previous leaks and the hardware looks set for a much leaked August launch.
