Test Bed and Setup
As per our processor testing policy, we take a premium category motherboard suitable for the socket, and equip the system with a suitable amount of memory running at the manufacturer's maximum supported frequency. This is also typically run at JEDEC subtimings where possible. It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance. While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.

Please note we are still using our 2019 gaming test suite for CPU reviews with a GTX 1080. We are in the process of rewriting our gaming test suite with some new tests, such as Borderlands and Gears Tactics, as well as changing the settings we test and moving up to an RTX 2080 Ti. It's going to take a while to do regression testing for our gaming suite, so please bear with us.
Many thanks to...
We must thank the following companies for kindly providing hardware for our multiple test beds. Some of this hardware is not in this test bed specifically, but is used in other testing.

Scale Up vs Scale Out: Benefits of Automation
One comment we get every now and again is that automation isn’t the best way of testing – there’s a higher barrier to entry, and it limits the tests that can be done. From our perspective, despite taking a little while to program properly (and get it right), automation means we can do several things:
- Guarantee consistent breaks between tests for cooldown to occur, rather than variable cooldown times based on ‘if I’m looking at the screen’
- It allows us to simultaneously test several systems at once. I currently run five systems in my office (limited by the number of 4K monitors, and space) which means we can process more hardware at the same time
- We can leave tests to run overnight, very useful for a deadline
- With a good enough script, tests can be added very easily
Our benchmark suite collates all the results and spits out data as the tests are running to a central storage platform, which I can probe mid-run to update data as it comes through. This also acts as a mental check in case any of the data might be abnormal.
We do have one major limitation, and that rests on the side of our gaming tests. We are running multiple tests through one Steam account, some of which (like GTA) are online only. As Steam only lets one system play on an account at once, our gaming script probes Steam’s own APIs to determine if we are ‘online’ or not, and to run offline tests until the account is free to be logged in on that system. Depending on the number of games we test that absolutely require online mode, it can be a bit of a bottleneck.
Benchmark Suite Updates
As always, we do take requests. It helps us understand the workloads that everyone is running and plan accordingly.
A side note on software packages: we have had requests for tests on software such as ANSYS, or other professional grade software. The downside of testing this software is licensing and scale. Most of these companies do not particularly care about us running tests, and state it’s not part of their goals. Others, like Agisoft, are more than willing to help. If you are involved in these software packages, the best way to see us benchmark them is to reach out. We have special versions of software for some of our tests, and if we can get something that works, and relevant to the audience, then we shouldn’t have too much difficulty adding it to the suite.

Darkworld - Wednesday, May 20, 2020 - link10500k?
Chaitanya - Wednesday, May 20, 2020 - linkPointless given R5 3000 family of CPUs.
yeeeeman - Wednesday, May 20, 2020 - linkYeah right. Except it will beat basically all and lineup in games. Otherwise it is pointless.
yeeeeman - Wednesday, May 20, 2020 - linkAll AMD lineup*
SKiT_R31 - Wednesday, May 20, 2020 - linkYeah with a 2080 Ti the flagship 10 series CPU beats AMD in most titles, generally by a single digit margin. Who is pairing a mid-low end CPU with such a GPU? Also if there were to be a 10500K, you probably don't need to look much further than the 9600K in the charts above.
This may have been missed on you, but what CPU reviews like the above show is: unless you are running the most top end flagship GPU and are low resolution high fps gaming, AMD is better at every single price point. Just accept it, and move on.
Drkrieger01 - Wednesday, May 20, 2020 - linkIt also means that if you have purchased an Intel 6th gen CPU in i5 or i7, there's not much reason to upgrade unless you need more threads. And it will only be faster if you're using those said threads effectively. I'm still running an i5 6600K, granted it's running at 4.6GHz - there's no reason for me to upgrade until either Intel and/or AMD come up with better architecture and frequency combination (IPC + clock speed).
I'll likely be taking the jump back to AMD for the Ryzen 4000's after a long run since the Sandy Bridge era.
Anyone needing only 4-6 cores should wait until then as well.
Samus - Thursday, May 21, 2020 - linkThat's most people, including me. I'm still riding my Haswell 4C/8T because for my applications the only thing more cores will get me is faster unraring of my porn.
Lord of the Bored - Thursday, May 21, 2020 - linkHey, that's an important task!
Hxx - Wednesday, May 20, 2020 - linkat 1440p intel still leads in gaming. It may not lead by much or may not lead by enough to warranty buying it over Intel but the person buying this chip is rocking a high end gpu and will likely upgrade to a high end gpu and the performance gap will only widen in intel's favor as the gpu becomes less of a bottleneck. So yeah pairing this with a 2060 makes no sense, go AMD. but pairing this with a 2080ti and a soon to be released 3080TI oh yeah this lineup will be a better choice.
DrKlahn - Thursday, May 21, 2020 - linkBy that logic the new games released since the Ryzen 3x000 series debut last year should show a larger gap at 1440+ between Intel and AMD. But they don't. And judging by past trends I doubt they will in the future either.As GPUs advance so does the eye candy in the newer engines, keeping the bottleneck pretty much where it always is at higher resolutions and detail levels, the GPU.
