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.

Not everybody has a rich daddy! Performance per dollar matters in all areas of life!It doesn't matter to very, very rich people or sucker fanboys!

Again the myth that rich people don't care about wasting money. So wrong. :D As for fanboyism, that kind of label gets hurled in both directions, but IRL has little meaning.Gothmoth - Thursday, October 5, 2017 - link
an overlcocked ryzen 1700 is bit for bit the best choice.. still.except for hardcore gamers.
and i bet intel paid you quite a bit to ignore stuff other (less intel biased) reviewers pointed out today.

Ryzen has no integrated GPU so it can't be the best choice for anyone without a discrete GPU (aka the vast majority of the market - about 70% as per q1 2017). Ironically the gamers are the ones more likely to snap up Ryzen as they have discrete graphics cards anyway...Ananke - Thursday, October 5, 2017 - link
I see the same, ryzen 1700 remains the best buy, followed by ryzen 1600, which recent batches seems to have 8 cores instead of 6, for around $170. They do come with heatsink, another $30 saved. With ok board it will total $250. Even better, readily built Dell gaming desktops can achieve around $800 with r580 8gb and 16 GB ram with 1700 ryzen vs above $1100 for similar Intel. It is literally no brainer choiceGastec - Saturday, October 14, 2017 - link
Wow there, rewind! "Ryzen 1600, which recent batches seems to have 8 cores instead of 6". Care to explain more?Ryan Smith - Thursday, October 5, 2017 - link
"and i bet intel paid you quite a bit to ignore stuff other (less intel biased) reviewers pointed out today."You'd lose that bet.
Now since we're apparently doing this Jeopardy style, please tell me how much you wagered so that I know how much I'm collecting. Since Intel isn't paying me, you will have to do. ;-)
In all seriousness though, taking sides and taking bribes would be a terrible way to run a business. Trust is everything, so losing the trust of you guys (the readers) would be about the worst possible thing we could do.

Are you happy for an overclocked Ryzen 1700 to be compared against overclocked Intel processors as well?gnufied - Thursday, October 5, 2017 - link
Your bench pages are either loading very slowly or displaying Gateway timeout.Ryan Smith - Thursday, October 5, 2017 - link
Thanks. Having the server team look into it.
