CPU Performance: Synthetic Tests
As with most benchmark suites, there are tests that don’t necessarily fit into most categories because their role is just to find the peak throughput in very particular coding scenarios. For this we rely on some of the industry standard tests, like Geekbench and Cinebench.
GeekBench4: Synthetics
A common tool for cross-platform testing between mobile, PC, and Mac, GeekBench 4 is an ultimate exercise in synthetic testing across a range of algorithms looking for peak throughput. Tests include encryption, compression, fast Fourier transform, memory operations, n-body physics, matrix operations, histogram manipulation, and HTML parsing.
I’m including this test due to popular demand, although the results do come across as overly synthetic, and a lot of users often put a lot of weight behind the test due to the fact that it is compiled across different platforms (although with different compilers).
We record the main subtest scores (Crypto, Integer, Floating Point, Memory) in our benchmark database, but for the review we post the overall single and multi-threaded results.
LinX: LINPACK
The main tool for ordering the TOP500 computer list involves running a variant of an accelerated matrix multiply algorithm typically found from the LINPACK suite. Here we use a tool called LinX to do the same thing on our CPUs. We scale our test based on the number of cores present in order to not run out of scaling but still keeping the test time consistent.
This is another of our new tests for 2020. Data will be added as we start regression testing older CPUs.
Cinebench R20
The Cinebench line of tests is very well known among technology enthusiasts, with the software implementing a variant of the popular Cinema4D engine to render through the CPU a complex scene. The latest version of Cinebench comes with a number of upgrades, including support for >64 threads, as well as offering a much longer test in order to stop the big server systems completing it in seconds. Not soon after R20 was launched, we ended up with 256 thread servers that completed the test in about two seconds. While we wait for the next version of Cinebench, we run the test on our systems in single thread and multithread modes, running for a minimum of 10 minutes each.

Pfft. You are hilarious.Spunjji - Tuesday, May 26, 2020 - link
Maxipad, the latest in the line of Gondalf imitators.Adm_SkyWalker - Wednesday, May 20, 2020 - link
Once again I find myself debating if I should upgrade. My current i7-6950X has held up better than I thought it would. I guess it's another year or two wait for me.Boshum - Wednesday, May 20, 2020 - link
I would be good with a beast like that for 5 more years.Icehawk - Saturday, May 23, 2020 - link
I’d wait until a component like mobo dies, that’s what got me to move from a 3770 about a year ago to a 8700 - mobo died and they were pricy and old. Replaced my wife’s i5 from same gen with a 3900X though recently and gave her the intel box. I’m a gamer but I do a lot of encoding so felt AMD offered a better mix and allows me to use my 450W fanless PSU. But aside from encoding speed I barely notice a difference from that 3700.Dug - Wednesday, May 20, 2020 - link
The problem with all these charts is that they are inconsistent.There are so many variables that aren't shown that it doesn't make sense to show these.
Most of this has to do with how motherboards handle the cpu's and what their default settings do.
There can be a 15% swing in AMD motherboard default settings between brands. Not to mention things like pbo on or off, infinity fabric, memory timings, etc.
I don't know about the Intel side. I remember their settings made less difference unless it was just cpu clock speed.

Agree with the sentiment, but you kinda stacked the deck with that last statement.Most of the Z490s are now supporting much higher speed RAM (up to DDR4-5000) and even intel 9th gen were good at overclocked RAM, while AMD systems rarely get above 3600Mhz. It shows if you look at something like PCMark 10 where the top 100 systems on almost all of the charts is completely dominated by intel. All of them are overclocked of course, but all of the top AMD systems are also overclocked.
What I would like to see is something along the lines of a i5-10600K vs AMD 3600 vs AMD 3600X, but not using 'all the same components other than mobo and CPU'. Take those 3 chips and build the fastest system you can with them. Use that PCI 4.0 NVMe and GPU on AMD, use that 4800Mhz CAS 18 RAM on the Intel. See what happens.

Ok, part of me would be curious to see what Intel could (or couldn't) do with an 11th Gen spin of their 14nm process.Findecanor - Wednesday, May 20, 2020 - link
The "Security" portion of this article is not really comprehensible. I can't guess what the author is thinking. The author needs to write it down in actual words what these things mean.Security on Intel processors is what is holding me off from buying any Intel CPU for the time being.
I consider myself pretty knowledgeable about the actual vulnerabilities themselves, and how they work, and how they can be mitigated -- in theory --, but if I have not kept up with every little tidbit of news about security on Intel's processors in particular, that portion of the article tells me absolutely NOTHING.

These chips are impressive, and for people with a need to build a system today, and a preference for Intel, they are reasonably competitive. So I am favorably impressed, even if AMD would remain my own choice at the moment. I still do believe that in the long run, Intel does have the means to regain leadership, so that in a year or two or five, AMD will be back to being in second place (but in second place like the previous generations of Ryzens, not like the Bulldozer years). I don't know, though, if even Intel will be able to keep up at the process end; even it may have to go fabless after 10nm, which would have significant implications for the industry.
