Benchmarking Performance: CPU Legacy Tests
Our legacy tests represent benchmarks that were once at the height of their time. Some of these are industry standard synthetics, and we have data going back over 10 years. All of the data here has been rerun on Windows 10, and we plan to go back several generations of components to see how performance has evolved.
All of our benchmark results can also be found in our benchmark engine, Bench.
3D Particle Movement v1
3DPM is a self-penned benchmark, taking basic 3D movement algorithms used in Brownian Motion simulations and testing them for speed. High floating point performance, MHz and IPC wins in the single thread version, whereas the multithread version has to handle the threads and loves more cores. This is the original version, written in the style of a typical non-computer science student coding up an algorithm for their theoretical problem, and comes without any non-obvious optimizations not already performed by the compiler, such as false sharing.
CineBench 11.5 and 10
Cinebench is a widely known benchmarking tool for measuring performance relative to MAXON's animation software Cinema 4D. Cinebench has been optimized over a decade and focuses on purely CPU horsepower, meaning if there is a discrepancy in pure throughput characteristics, Cinebench is likely to show that discrepancy. Arguably other software doesn't make use of all the tools available, so the real world relevance might purely be academic, but given our large database of data for Cinebench it seems difficult to ignore a small five minute test. We run the modern version 15 in this test, as well as the older 11.5 and 10 due to our back data.
x264 HD 3.0
Similarly, the x264 HD 3.0 package we use here is also kept for historic regressional data. The latest version is 5.0.1, and encodes a 1080p video clip into a high quality x264 file. Version 3.0 only performs the same test on a 720p file, and in most circumstances the software performance hits its limit on high end processors, but still works well for mainstream and low-end. Also, this version only takes a few minutes, whereas the latest can take over 90 minutes to run.

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!
