Benchmarks

Computer Chess Benchmark List

There are many CPU benchmark websites that measure the performance of your computer such as PassMark that can compare 3 CPU's at the same time. But what do they actually measure? and what does it mean for the speed of a chess program? For single thread performance the site reports:

Intel Core i7-860 @ 2.80GHz

Intel Core i7-8700 @ 3.20GHz

Intel Xeon E5630 @ 2.53GHz

1229

2630

1113

Does this automatically mean the i7-8700 will perform a factor of 2630/1229=2.13 faster than the i7-860 for chess engines? Let's find out. And create a simple benchmark and report the results in the below contact form.

 

The rules

1. Make sure that as less as possible software is running in the background.

2. Download and unzip bench and double click CPU-1 which will start the Stockfish 9 build-in benchmark.

3. Check if the total number of nodes exactly matches 81.858.477

4. If the number is correct contribute the Nodes/second in the contact form below.

 

If you want to contribute to multithreading alo then repeat steps 1-4 with CPU-4 | CPU-8 | CPU-16. Note that contrary to single thread there are no fixed nodes numbers in multi-threading.

Comment

While the PassMark almost has doubled the NPS for a chess program by far has not, it's only 20%.

While the PassMark indicates a 50% speed increase for a chess program it's only 5%.

In other words, CPU benchmarks websites like PassMark can not be trusted for chess programs and the Intel

hardware progress since 2009 for chess is disappointing.

Remarks

 

To identify your hardware download CoreTemp and run it.

 

Turbo=off can be recognized if the (red marked) frequency is a constant number. If the number fluctuates Turbo=on.

 

Hyperthreading=off can be recognized if the (green marked) number of cores and threads is equal else Hyperthreading=on.

 

Technical

 

Note that CPU-1 runs the 42 positions at depth=20 and CPU-4|8|16 at depth=21
