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.

Ian,i'm interested in the details of the agility benchmark? how many photos are in your dataset and at what resolution? am doing similar work and i notice the working time doesn't seem to be linear with the number of photos.

reading this article again i must say im realyl ashamed. anandtech was once a great place but now it´s just like car magazines. who pays best gets the best reviews. where is the criticism? everyone and his grandmother things intel has big issues (tim, heat, pci lanes nonsense product) are you bend over so intel can inject more money more easily?damianrobertjones - Thursday, July 27, 2017 - link
Is your shift key broke? Where's are your capitals?zodiacfml - Wednesday, July 26, 2017 - link
Impressive benchmarks. I could not ask for more. This revealed that Intel clearly doesn't have the premium or value position anymore. It is simply not there. They have to be in the 10nm process now to be superior in value and/or performance.Walkeer - Wednesday, July 26, 2017 - link
Hi, what RAM frequency is the AMD platform running on? if its the official maximum of 2666MHz, you can get +10-15% more performance using 3200MHz or faster memorywarner001 - Wednesday, July 26, 2017 - link
Hey, This is a very useful post for the new ones. Thanks a lot. please visit http://forums.cat.com/t5/user/viewprofilepage/user...warner001 - Wednesday, July 26, 2017 - link

Please redo the Ryzen benchmarks using DDR3200 now it is officially supported, and also use the latest updates of the games - eg ROTR v770.1+ where Ryzen gets a 25% increase.You can't compare one platform with the latest updates, and the other without - thats pointless
