CPU benchmark advice

I ave a Intel 2600k(3.4Ghz, 4.4Ghz w/ Turbo Boost) and I did a quick benchmark for you. Using Diamond 1.6.8, no GUI, using Powershell to measure.

1 Instance, 35 Rounds:

- 48.1 seconds Total

2 Instances, 35 Rounds:

- 47.28 seconds Total
- 24.17 seconds per Battle

4 Instances, 35 Rounds:

- 1:05 Minutes Total
- 15.2 seconds per Battle

8 Instances, 35 Rounds:

- 1:31 Minutes Total
- 11.37 seconds per Battle

Though I noticed that Powershell had a small delay between creating each instance, not sure why. I haven't had a look at RoboResearch, so maybe I'll have a look at that later.

Not sure if it just my benchmark setup, but if Rednaxela could send over the benchmark setup, maybe I'll be able to test it in the same way.

I'm just running the unix command "for i in {1..8}; do sh -c "time ./robocode.sh -nodisplay -battle battles/sample.battle > /dev/null &"; done" with the battle file set to run diamond versus diamond 35 rounds. I then take the average time outputted from each "time" command and use that.

Hmmm... 8 instances... I just tried 8 instances here and got the following result on my Phenom II 1090 X6 that's clocked up from 3.2GHz to 3.6GHz..... 1m35s per instance average, 11.90 seconds per battle.

Voidious: It seems like the 2600K may not be as fast for robocode as non-robocode benchmarks would lead you to believe?

Yep, I was guessing closer to 5-6x - the PassMark score is 5x my current CPU, and I figured if anything Robocode would scale better to more cores than the average benchmark. I really appreciate all the real world info! Definitely impacting my purchasing decision.

Oh, and one little warning, when I run the X6 1090 at the OCed 3.6GHz, with 8 robocode instances, and stock cooling, it pushes the CPU temperature awfully high (61C when the CPU is spec'ed for a maximum of 62C). Pondering clocking it back to 3.2GHz now that I noticed that, haha.

Mobile processors are spec'ed completely different for heat from what I've seen (My old Core2Duo laptop was spec'ed for up to 105C for instance)

Aha, I think I found why...
Compare i7-2640M (mobile) and i7-2600K. Notice that the mobile part is specified with "Tjunction" whereas the desktop is specified with "Tcase". It appears desktop CPUs use temperature measurements of the packaging temperature whereas mobile parts directly measure the die temperature. Fun stuff :)

Thanks Rednaxela! I've rerun the test without the little delay between starting up instances, and calculated it the same way (if I understood it right) and this is what I got 1:17 per instance average, 9.70 per battle.

I don't have *nix to test on my home computer at the moment. My server has *nix, but it's stuck with a Quad-core Xeon in it ;)
