Benchmarking Performance: CPU Office Tests
The office programs we use for benchmarking aren't specific programs per-se, but industry standard tests that hold weight with professionals. The goal of these tests is to use an array of software and techniques that a typical office user might encounter, such as video conferencing, document editing, architectural modeling, and so on and so forth.
All of our benchmark results can also be found in our benchmark engine, Bench.
Chromium Compile (v56)
Our new compilation test uses Windows 10 Pro, VS Community 2015.3 with the Win10 SDK to compile a nightly build of Chromium. We've fixed the test for a build in late March 2017, and we run a fresh full compile in our test. Compilation is the typical example given of a variable threaded workload - some of the compile and linking is linear, whereas other parts are multithreaded.
For our compile test, it would appear that the extra memory width afforded by the quad-channel memory of Skylake-X can have a direct benefit in compile performance.
PCMark 10
PCMark 10 is the 2017 update to the family favorite, PCMark 8. PCMark 8 has been part of our test bed since the latest update in Q1. For the most part it runs well, although for some processors it doesn’t recognize, some tests will not complete, leading to holes in our benchmark data (there’s also an odd directory quirk in one test that causes issues). The newest version, PCMark 10, is the answer.
The new test is adapted for more 2016/2017 workflows. With the advent of office applications that perform deeper compute tasks, or the wave of online gamers and streamers, the idea behind PCMark 10 is to give a better ‘single number’ result that can provide a comparable metric between systems. Single metrics never tell the whole story, so we’re glad that Futuremark provides a very detailed breakdown of what goes on.
Ganesh’s article on PCMark 10 goes into more detail than I will here, but the ‘Extended Benchmark’ runs through four different sets of tests: Essential, Productivity, Creation and Gaming. Each of these have sub-test results as well, including startup performance, web performance, video conferencing, photo/video editing, spreadsheets, rendering, and physics, which you can find in Bench.

Despite originally coming out in 2008/2009, Futuremark has maintained PCMark8 to remain relevant in 2017. On the scale of complicated tasks, PCMark focuses more on the low-to-mid range of professional workloads, making it a good indicator for what people consider 'office' work. We run the benchmark from the commandline in 'conventional' mode, meaning C++ over OpenCL, to remove the graphics card from the equation and focus purely on the CPU. PCMark8 offers Home, Work and Creative workloads, with some software tests shared and others unique to each benchmark set.

In speech: "grateful" to AMD for reinvigorating competitionIn deed: gives money to Intel, effectively taking part in keeping AMD down for that bit longer, maybe causing them to return to non-competitive state, upon which AMD is blamed for being non-competitive once more.
The Invisible Hand doesn't seem so wise, sometimes.

AMD did a fantastic job with Ryzen while Intel were busy milking their customers dry. We should support AMD when they need us most. If AMD goes down it would suck not for the industry but technology as a whole.leexgx - Monday, October 16, 2017 - link
at least you can enable MCE to make all cores run at 4.6Ghz (make sure you got a good cooler) 8700K would allow you to goto 4.9-5.1Ghz with very good coolinglordken - Saturday, October 28, 2017 - link
what a "brilliant" asshardware , your Kudos worth shit to amd as they cant fund further r&d with it. But sure, run to support your milking master because they finally bothered to release, after 10 years, 4+ core for mainstream...Budburnicus - Wednesday, November 1, 2017 - link
Salty salty salty people! AMD are big boys too, they can fight for themselves. It is called a FREE MARKET, and until Ryzen, AMD had nothing to even come within spitting distance of an i7-2600k!Which is coincidentally what I upgraded to my 8700k from. Running 4.8 GHZ on all cores for now, I still have plenty of thermal room, so once more people have figured out all the minute settings, I will just leave it at 4.8 til then!

Thas me, ahead of 96% of all results! And that single threaded perf, is totally insane - as is multi-core, nothing short of 16+ threads can touch it.

I like how Ryzen 5 1600 beats the much higher TDP and much higher priced Coffee Lake in Civ Vl.This should ring a bell how software is written!!!

...cherry pick one benchmark, claim that it's the only one that matters...*cough*AMD fanboy*cough*

I don't own anything AMD!Drink some water and stop that coughing!
