Intel 8th Generation Core i7 8700K & Core i5 8400 Review


Intel 8th Generation Core i7 8700K & Core i5 8400 Testing:

SiSoft Sandra is a diagnostic utility and synthetic benchmarking program. Sandra allows you to view your hardware at a higher level to be more helpful. For this benchmark, I will be running a broad spectrum of tests to gauge the performance of key functions of the CPUs.

Processor Arithmetic


Multi-Core Efficiency



Memory Bandwidth



Cache and Memory




AIDA64 Extreme Edition is a software utility designed for hardware diagnosis and benchmarking. I will be using the CPU Queen test that looks for the solution to the "Queens" problem on a 10x10 chessboard. This tests the branch prediction capabilities of the processor. The FPU Mandel test measures double precision floating point performance through the computation of several frames of the "Mandelbrot" fractal.



In the Sandra testing, the Coffee Lake processors perform very well. In just about every test, the Core i7 8700K was outperforming the R5 1600X and delivering significant boosts in performance over the Kaby Lake and Skylake 4C/8T SKU's. In the AIDA64 tests, again I see the Coffee Lake SKU's doing well by comparison.
