| Dual CPU's Run games better? |
| (1/1) |
| Yoodaa:
I have a chance to aquire a dual rig and was wondering because mame is CPU intensive, would dual cpus help performance? Does mame or mamewah support dual cpus? Anyone out their experimented with this? I am talking dual Pentium 3 866's. Thanks all. |

No http://www.mame.net/mamefaq.html#m11 |
| AmericanDemon:
SirPoonga is correct. I tested this w/ test rigs of AMD 1800XP and a Dual AMD 1800MP. Systems ran nearly identical. Mame only uses on processor. I sincerely wish someone would find a way to take advantage of the extra horsepower though. |

Trouble is that they sync issues needed would take an extra processor. I hope the seperate the parts that could be seperated without much problems. processors + memory on one processor. Video and input on another non-essentials. The video memory might be a sync issue.. but shouldn't be that bad since most multi-processor systems can quickly sync memory. Plus you might get a trible buffer working on the P&M processor could fill in a specific memory location... And the only sync would be around switching between the pages... IE, move all non-essential parts to another processor. but take note... you wont' get any extra games running... Bottle necks for most slow games wont be effected by this... This is more of a future... next amd and intels will problabl be multiprocessors. |

if your hyperthreading your as close to multiprocessing as your going to get with mame. my 3.4ghz extreme shows as two processors and all my system info indicates that i am running a multiprocessor setup. |
