Core i7 8700K vs Core i5 8600K vs Ryzen 7 2700X vs Ryzen 1700 vs Xeon E5-2680 V4

[Artas1984]

Greetings! Over the past 6 months i've been assembling and selling computers, so i had lots of processors to test! This benchmark is dedicated to productivity applications only!!!

This CPU benchmark is dedicated to folks who are looking a for a budget friendly workstation build - for those who can't afford new AMD X399 or Intel X299 systems with Ryzen Threadripper or Core i9 processors, but are checking out Z370 and X470 platforms with flagship Core i7 8700K and Ryzen 7 2700X processors. Not only this will be a massive direct battle between these two chips, but also included are the other alternative chips, like Ryzen 7 1700 and Core i5 8600K, which cost less and can provide enough performance for your WS rig. Without a doubt, older Core i5, Core i7 and Xeon processors have been included in the benchmark to provide comparison and perhaps competition to the modern chips.

At first i was assembling workstations with Broadwell-EP Xeon ES processors, since they are being sold real cheap at ebay. Even the 14 core/28 thread CPU can be found for 400 - 500 $, while 6 months ago it was going on sale for 700 $. The 18 core/36 thread Broadwell-EP Xeon was being sold for 1000 $, so it was a too expensive shot. That got me thinking:

- ''what if it ain't worth buying those Xeons, what if Core i7 8700K or Ryzen 7 2700X are actually faster, what if i am making a mistake by assembling workstation computers with Xeon chips''?

Ye, you get the idea where this benchmark came from now...

These processors have been tested in real time programs with custom presets as well as in standard synthetic benchmarks:

CPU-Z
Cinebech R15
Vray
Corona
Handbrake video compression (multiple tests)
Blender rendering tests (multiple tests)
Irfan photo conversion tests (multiple tests)
SPEC 3D rendering simulation tests (multiple tests)

nice tests. Only missing thing for me is a stock 8700k.

Intel Xeon E5-2683 V4 tested. 16 cores/32 threads, 4 MB L2, 40 MB L3. Another engineer sample, that manages 2.3 GHz turbo boost on all cores. Since i am on a new Windows 10 computer, i could not test the full list of the previous benchmarks, so here what's been tested:

CPU-Z MULTI THREAD 5500 points.
CINEBENCH R15 1940 points.
V RAY 1:09 s.
CORONA 1:58 s.
BLENDER BMW 4:47 s.
BLENDER CLASSROOM 15:19 s.
BLENDER PAVILLON 16:46 s.
BLENDER SPLASH 9:05 s.
BLENDER BENCHMARK 36:58 s.
