--- Quote from: xmenxmen on November 09, 2007, 02:32:55 pm ---For those interested, most of the optimized versions are available online: http://redump.emubase.de/mame.php Wonder if there's much differene between the P4 and PM version? --- End quote --- More than you might expect, the Pentium M/Core Duo family of processors have more in common with the Pentium 3 than they do with Pentium 4 in many ways, the Netburst architecture used in the P4 was ment to scale all the way to 5Ghz, but due to pressure from the verious versions of the AMD Athlons Intel had to accelerate the scaling of the P4s clock speed, thus they hit a clock speed wall at 3.8-4ghz where they couldn't go any higher because the manufacture processes where now 3 years behind the clock speed curve of the P4. So instead they gave us two years of bandaid fixes with the prescott cores while they when back and developed the Core 2 Duo. (There is a lot more to the history of this but I don't want to bore everyone, and AMD still has the better system architecture, but Intel has the better Core Architecture at the moment) I knew of the website, but I figured it was better if everyone learned make theier own builds. The pre optimised builds tend to get out of date, like mame is now at 0.120u3 and the site still at 0.120u2 but it will catch up in a few days. |

--- Quote from: TheManuel on November 08, 2007, 12:44:31 pm ---A recommendation for the futue is to run a fixed number of frames rather than a fixed number of seconds. The reason is that if someone wants to compare his benchmark to yours (if you care, anyway), and his/her computer is slower, that computer will run a shorter sequence of the game in 240sec so it will not be a 100% apples to apples comparison since some parts of the attract mode of a game are more taxing than others. --- End quote --- Alread done. Mame's "seconds" in the benchmark is emulated seconds and Mame switched the benchmark/test option to "-seconds_to_run" from "-frames_to_run" a little while ago. IOW, a game with 60 Hz refresh runs 600 frames if -str 10, no matter if the game runs at 500% or 50%. The only "differences" between -ftr and -str changes between games with different refresh rates. On 53 Hz games, -ftr 600 equals about -str 11, and -str 10 equals about -ftr 530; on 61 Hz games, -ftr 600 falls between -str 9 & -str 10, and str 10 equals about -ftr 610. |

Thank you for correcting my ignorance. Things have changed in last three an a half years I have been away from the hobby. By the way, it is good to see you (your web persona I guess) around. You were very helpful when I was building my control panel years ago. |

Hit "post" button too early... I am a little frustrated. I have tested i686, PM and P3 builds of MAME and they all yield virtually the same result, at least on the game I am benchmarking against which is Mace (it sucks, by the way). Could I be missing something? Even the -mt parameter makes no difference and I did set osdprocessors=2. I am using the same command line parameters as tar-nz on my Core 2 Duo e4300 overclocked to 2.4GHz. I would like to see the same kind of improvements (proportional to my processor speed) tar-nz saw with the PM build but it is not working for me. Any pointers will be appreciated. |

Hey guys could I get a couple of opinions I have stopped setting up my new quad until i get some good feedback used to video did not matter but now which video card would you guys use 1. pci-e arcadevga or I have a extra 8800 gts laying around. My monitor is a betson I did some performance test & the 8800 just runs all over the arcadevga. thanks for your help dm |
