SiSoft Sandra 2016
Again, the 8700K and even the 8400 are showing some impressive results. In the Sandra MT testing, the 8700K results in a score that is 50% faster than the 7700K (which makes sense, it has 50% more cores and threads). Even the Core i5-8400 results in a higher score by 5% as a result of having 6 TRUE cores as opposed to four cores with HyperThreading. The AMD Ryzen 7 1800X and 1700X still score higher than the new 8700K, however.
From a single threaded view, there is no faster stock CPU on the market than the 8700K, jumping past the 7700K by 6% or so. Here, Intel now holds a lead of 35% over the Ryzen 7 1800X. For the multi-threaded portion of Geekbench, the 8700K is 24% faster than the 7700K and just edges past the Ryzen 7 1800X, despite it have more cores and threads available to it.
Euler continues to be an interesting test, at least for comparing Intel to Intel performance. Here, the 8700K is 14% ahead of the 7700K in the single threaded result, and peaks at 17% at the higher thread counts.
