Intel Core i7-8700K and Core i5-8400 get tested in SiSoft Sandra

Benchmark results of Intel's upcoming Core i7-8700K and Core i5-8400 processors popped up in the SiSoft Sandra benchmark database. For the upcoming 8th generation Core processors, Intel is promising performance gains of over 40 percent over the current 7th generation Core processors. Most of these gains originate from the addition of extra cores and higher frequencies.

The Sandra scores reveal the six-core, twelve-threaded Core i7-8700K is indeed quite a bit faster than the quad-core, eight-threaded 7700K:

There is a 45 percent increase in performance, in the "processor arithmetic" test; and a 47 percent increase in the "processor multimedia" test. These two test-suites are multi-threaded, and hence benefit from the two added cores, which in turn add four additional logical CPUs, thanks to HyperThreading. "Processor cryptography" sees a 12 percent increase. The single-precision and double-precision "Scientific Analysis" tests, which again are multi-threaded, see 26 percent and 32 percent performance gains over the i7-7700K, respectively.

Next there are also scores of the Core i5-8400, this is an interesting chip as it delivers six cores (with six threads) for around $200. Here's how it performs in Sandra versus the Core i5-7600K (which is succeeded by the 8600K):

Despite that, we see a healthy 40 percent increase in "processor arithmetic" performance, a staggering 50 percent increase in "processor multimedia" performance, a 14 percent increase in "processor cryptography," and 30 percent and 17 percent increases in single- and double-precision "scientific analysis" results, respectively.

Interesting results, it will be exciting to see how these Coffee Lake chips stack up in in-depth reviews when they hit the market in October.
