Rating lists and hardware

CPU
- Intel i5-6600k @ 4,2 GHZ, 16GB RAM
- Intel i7-4770 @ 3,8GHZ, 16GB RAM
- Intel i5-4440 @ 3,3 GHZ, 16GB RAM
- AMD Ryzen 7-2700 @ 3,5GHZ, 16GB RAM
- AMD Ryzen 5-1600 @ 3,5GHZ, 8GB RAM
- AMD Ryzen 5-1500x @ 3,8GHZ, 8GB RAM

I might be wrong, but I beleive that even though the Ryzen zen=1 series (1500X/1600) have AVX2, they do not have 256-bit channels for the operations, and they are emulated with 2x128 bit lanes, basically making the AVX2 versions no better than their smaller vector SSE3/SSSE3/SSE4.X.

For example, AVX2 is not faster than AVX on my Ryzen 1950x, but is massively faster on my Ryzen 3700x. The same holds true for some Intel machines. So ... test everything with the 2700

I only have one machine with avx2.

Do you use any other hardware in testing engines for CCRL, or is this the only machine you use?

Damn, the same happens in my R7 1700... time to upgrade and lose my family

My dual xeon octal (which I use for 2x4CPU testing) is non-popcount.
My i5 is popcount, but not bmi2. I run tournaments on it.
My Q8200 is non-popcount. I run gauntlets for weaker engines on it.
The i7 is used to run gauntlets for the stronger engines, and sometimes for higher Amateur Series divisions.

[Modern Times]

when available:

Ryzen 9 5900X (cutechess concurrency 12 for 1CPU matches, concurrency 3 for 4CPU matches)
Intel i9 10900 (cutechess concurrency 10 for 1CPU matches, concurrency 2 for 4CPU matches)

Old AMD FX8350 popcount support, no AVX2, works perfectly but now retired and gathering dust.

Intel(R) Core(TM) i5-4690K CPU @ 3.50GHz (Haswell, AVX2 and BMI2 capable)

That's all I have.

I wonder how much of a discount we could get if we collectively bought a large amount of Cloud Compute time?

Hi Andrew,

I am not in a position to discuss the technical details due to lacking knowledge...

But I tried all compiles of Ethereal 13.00 on all mentioned machines using "go nodes" command in console mode. I think it were 20 million nodes.

Here are the results/conclusions:
- fastest variant is the pext-avx2-compile on 6600k and 4770 intel machines. 6600k is a bit faster due to to higher clock speed (4770 cannot be overclocked that much, its without "k")
- I disagree that the 2700 (without "x"!) is faster/fits better for NN-engines than the Ryzen 1xxx series. NPS are fairly equal.
- Maybe a Ryzen 2700 (or higher) with "x" will be considerably faster, because it can be better overclocked. Maybe one can overclock my Ryzen 2700 for more than 10%, but I look at stability first, not at ultimate performance.

So ... test everything with the 2700

No, I'll take 6600k and 4770 for Ethereal and other TOP engines...
