4Ghz Core 2 Duo vs M.A.M.E. 0.120 (benchmark results)

Just a heads up Mame Compiler 64 has been released in the Software forum. This should make it easier to compile custom 64bit versions of Mame with optimizations for your CPU. So it might be worthwhile taking a look and doing some more tests for Mame64 if you don't know how to compile 64bt Mame already.

Fantastic!!!  I'm just waiting for UPS to arrive with my laptop and then I'll be looking to compile a 64 bit version of MAME.  This is great news!   ;D

taz-nz:

Well after way to many months waiting, I scored myself an Core 2 Duo E8500 engineering sample (It helps to know the right people sometimes) So out with the old 65nm E6850 and in with the new 45nm E8500 (3.16ghz 1333fsb stock). Now I've had this CPU a little over 24 hours as I type this and it's been in the my system less than 20, so I still need to tweak a few things, but 4.4ghz (4410mhz) seams to be my limit right now, while it will boot windows and run everyday apps at 4.5ghz, it locks after only a few minutes at 100% load, Air-cooling just isn't enough to keep it cool.  4.4ghz @ 490mhz FSB looks to be stable for the mean time more testing is need, but I may just splash out on a new case and water cooling kit and get it over and done with.

So now I bring you Core 2 Duo E8500 @ 4.4ghz vs MAME 0.123u1.  >:D (benchmark run on MAMEUI 64bit v123.1 in Vista Ulimate 64bit)

ROM NAME   
- 1942      7114.33% (4.5ghz CPU drag race)
- a51site4   225.85%
- airco22b      148.66%
- alpinerd      87.86% (still can't get this sucker to run at 100%)
- biofreak                   154.86%
- blitz2k      172.00%
- blitz99      164.36%
- blitz      176.95%
- calspeed   216.95%
- carnevil   301.32%
- crusnusa   289.38%
- crusnwld   258.61%
- cybrcomm   138.90%
- Daytona   (colours look better, but crashes within seconds unable to benchmark)
- gauntdl   143.39% (was noticably slower this time round, not sure why just yet)
- gauntleg   166.17%
- gradius4   122.94%   (actual used MAMEUI 32bit for this one, still in Vista 64bit)
- hyprdriv   189.75%
- mace      268.49%
- mk4                       186.26% (this is actual too high, but in game is over 100% all the times.)
- offroadc   468.22%
- propcycl   142.66%
- radikalb   178.03%   
- raveracw   118.34%
- ridgerac   159.87%
- scud      30.77% (Ha, back over 30% again, but this still needs alot of work)
- sfrush   219.12%
- sidebs2   178.88%
- speedup   182.32%
- starblad   156.96%
- surfplnt   170.44%
- tenthdeg   97.93% (so close to that magic 100%, but dips to the 70's in some areas game)
- timecris   149.15%
- wargods   406.11%
- wg3dh      387.59%
- xevi3dg   398.29%

Some scores are down on where I would have expected them, but that could just be the Dev's at work or my install of Vista 64 maybe a little broken after the dozen or so lockups testing overclocking settings, I'll probably reinstall and benchmark one of the older builds to confirm which it is.

To anyone looking at building a MAME Monster Machine, I suggest picking up an Core 2 Duo E8400, should be a easy 4ghz overclock with little added voltage needed, just make sure you upgrade the heatsink as they still get hot went you push them hard and the new stock HSF is tiny compared with the older Core 2 Duo's. (I can confirm crazy tempature readies are the order of the day with the E8#00 series CPUs, one core never reads below 44 deg C well the other drops to 29 deg C, over 44 deg C the move together like you would expect.)

I've download this and I give it a go in the near future, more benchmarks will follow once I get everything tweaked a little better.

If anyone knows of any ROMs or Drivers I should test please let me know, I'm down to only half dozen Roms that are putting up any resistance now.






releasedtruth:

Very impressize performance Taz, you are really doing us an awesome service here. I've been looking at the Quad core for experimental purposes, see what's possible there, even if it's not in the same league it'd be interesting to see how the architecture works at least.

headkaze:

Those results are pretty amazing taz! I got myself an E8400 recently but havn't had a chance to overclock it yet.
