DDR4-2666 vs. DDR4-3000
Initially we only had DDR4-2666 on hand for testing which might have put the Core i7-6700K at a slight disadvantage when compared to the DDR3-2400 memory of the 4790K due to weaker timings and only a slight frequency bump. Just hours before the official launch we managed to acquire some DDR4-3000 memory and took the time to re-test some applications ... here are the results.
DDR4-3000 offered a 29% boost in memory bandwidth for the Core i7-6700K when compared to the DDR4-2133 configuration taking the bandwidth to 33.6GB/s.
The faster DDR4-3000 memory allowed for a 3.5% performance increase in the Hybrid encoding test taking the Core i7-6700K to 2.6fps and making it slightly faster than the 2.55fps of the 4790K.
The extra memory bandwidth had little to no impact on the Cinebench R15 scores.
The Core i7-6700K was able to shave 0.1 seconds off the Excel 2013 workload to now match the 4790K.
The Core i7-6700K still struggled in our 7-zip benchmark and was noticeably slower than the 4790K.
The Core i7-6700K was considerably faster in Adobe Photoshop CC with the DDR4-3000 memory, improving performance by 12%.
