Title: CHD games
Post by: sol on October 04, 2006, 05:58:38 am
Hello

Which processor would handle these the best
A Intel pentium D Dual Core 3.4 GHz/2x2mb cache
or a Intel core 2 Duo (fsb 1066MHz,2.4GHz, 4MB cache)

 :)

Sheesh, that's some serious beef to throw at a game so I'd get some winmark stats, just to get a baseline, but you should be able to run most things (standards) with no problem. I've seen kinst run pretty well on a Sempron 3200 so you're crushing that system. That said, it's rare to find anything else that works much at all

     You won't be able to run 95% of the chd games. It is not a machine issue it is the emulator. I may be stating this incorrect from a technical standpoint but the jist of its meaning is the same. The MAME devs did not code mame to be playable but to be a replica of the arcade experience. A rule of thumb you need 10X the processor power that the original game used to play the game. I've seen this number used many a times on this very subject but to run the chd games you would need a 10ghz processor. That being straight processor power not multi processors or multi-threaded processors as MAME does not utilize multiple processors.
     So basically you're out of luck for now. If you'd like a better explaination search the site as there are a lot of threads on this very subject and those that know have answered with more technical mumbo jumbo than I just have...

Although that is usually the case with MAME games and processing power needed, I'm sure I've seen some of the newer CHD games run fairly smoothly on a mid-range system.
There could have been other factors (eg. running optimized mame code, frame skipping, other tech stuff I don't understand etc) but it definitely can be done, at least with some games.

PS. I assume asking where to find CHD files comes under the same rule as ROM files... ie don't?

More like 60-80% ATM, depending on if you're including clones or just the parents, but who's counting?

Core 2 smokes the P4.  Check out the benchmarks at mame32qa (http://mame32qa.classicgaming.gamespy.com/Bench.htm).  A P4 is not included any more, though; it's too slow.  In past benchmarks at the same page, the a64 3400+ usually beat the P4 3.4 gHz, except for the games running on playstation-like hardware.  And the Core 2 is beating the A 3700+.

Thats excellent thanks for the help, it looks like the core 2 for me, I did't realise there was a 3GHz version.  :cheers:

It's an overclocked 2.4Ghz chip.
