[App] Cpu Performance Tester

rootfan · Mar 30, 2014

This application simply does large amounts of mathematical operations on one, two, three, four, or eight threads (which corresponds to the number of cores used) and measures the amount of time it takes to complete. It makes it easy to see the cpu power of one computer compared to another. Enjoy

Some devices for comparison
Intel i7-3770 @ 3.4 ghz (quad core ht) -
1 Thread - 23 seconds
2 Threads - 23 seconds
4 Threads - 24 seconds
8 Threads - 27 seconds

Intel i5-3317U @ 1.7 ghz (dual core ht) -
1 Thread - 35 seconds
2 Threads - 36 seconds
4 threads - 40 seconds
8 threads - 1 minute 16 seconds

Intel Atom-Z3740D @ 1.33 ghz (bay-trail, quad core no ht)
1 Thread - 1 minute 24 seconds
2 Threads - 1 minute 24 seconds
4 Threads - 1 minute 25 seconds
8 Threads - 2 minutes 35 seconds

Cool. Looks easy to port to jailbroken RT; and chance of an ARM build? (I'd do it myself but I'm away from my dev machine at present).

Of course. I will just post it above for now.

GoodDayToDie · Apr 1, 2014

That would be great, thanks.

I'm somewhat amused by somebody with a C# logo in their profile image posting a C++ app but that does make sense for performance testing programs.

On Windows 8 (64 bit) it gives me the following error:

The program cannot be started, because MSVCP110.dll it missing.

You need .net framework or Visual c++.

Works on 7, my work machine which has a core 2 duo 4600(yup running one of these old guys!) scored 56 seconds on 2 threads.

@chazram: Cool (though not surprising) to see that the clock cycles per (arithmetic) instruction are basically the same between Intel and AMD (which allows the AMD's greater clock rate to smoke the Intel). Also interesting to see the difference between actually having eight integer cores (AMD) and having eight hardware pipelines but only four ALUs (Intel). It *is* actually a bit surprising to see how close the AMD is on 4 threads and 8, given the 8350 only has 4 floating-point ALUs and a good bit of the computation is FP. On the other hand, repeating the same operation over and over again can easily be optimized, possibly even my microcode.

Of course, real-world usage is a lot more than just crunching numbers over and over, but it's a pretty good set of ALU benchmarks.

Is the test loop doing floating point or integer calculation ?
shouldn't thread priority be high ?
Like memory consumption exceed the simple CPU Cache, how to be sure that results aren't influenced by ram quality ?

Should also be mentioned that the AMD floating point units consist of 2 128 bit FPU's which can be addressed by each half of a module independently or the 2 128 bit units can be ganged together to form a single 256 bit FPU. I think intel utilise a near identical unit. But I should think the effective 8 128 bit FPU's of the 8350 should suffice?

Any linux edition?
Want to test it on my hp.

I could write up a version for Linux using pthreads easily enough, but I forget whether Linux schedules pthreads on different processors or not. Different processes using fork/clone is more common, but not very efficient and not entirely in the original spirit of the test.

In other words, I *could* write it, but performance testing code for an OS should probably be written by somebody who has actually developed code for that OS in the last 5 years or so.
