4Ghz Core 2 Duo vs M.A.M.E. 0.120 (benchmark results)
<< < (92/104) > >>
Truecade:
Time to dig up this thread, I just upgraded to the new Intel Sandy Bridge processor and did some very preliminary testing last night. 

Here is what I have:
Core i5-2500 (3.3 Ghz stock)
Intel DH67CF Mini ITX board
4 GB Ram
MSI HD 5670 video card
Windows XP 32 bit SP3

I only tested a couple games, but everything ran really good.

I fired up Mace: the Dark Age and played it through to the end.  The framerates never dropped below 100% and game ran perfectly. 

Next up, Gauntlet Legends.  The game played very well with only a couple frame rate drop to 90ish% on the first stage of the mountain world.  For some reason I didn't have sound effects (the music worked fine), but that may have been due to the older version of MAME I was using or mismatched CHD/ROM files.  I will get a newer version of MAME tonight and do some more testing. 

I would have done more benchmarking, but I was having too much fun playing Mace the Dark Age.   ;D  So my very early thoughts are that the new Sandy Bridge CPUs are going to finally make almost all of those CHD games playable without overclocking.  With an unlocked Sandy Bridge CPU, overclocking is as easy as just changing the CPU multiplier in the BIOS.  So far the tech sites are saying 4.0 Ghz OC can be achieved very easily on air with the stock Intel cooler.  These are the perfect CPUs for MAME and with 64-bit Windows MAME performance would be even better. 

Nest up, I need to find a PCI-e vid card that is compatible with Soft 15Khz so I can test games running at their native resolutions with my NEC XM29.   :cheers:

Sorry to drag up an old thread, but I've tied reading this thread in a linear fashion and I just got confused  :dizzy:

My current setup is running a P4 3.0 HT, and plays most chd games ok. Gauntlet and Blitz are still kind of not there yet.

I'd like to drop in something overclocked to the 4.0 GHz range. I've read that the E8400 is a nice choice, but I don't know what motherboard and RAM to get.

Should I try getting my hands on a core i5 2500k? Is there a motherboard that will handle both chips, or are they different sockets?
scofthe7seas:
Since the thread is already back from the dead; Yes, those are different socket types. I'm pretty sure all of the core2blah processors are 775. there might be some newer ones that are not, but I have a core2quad, my mobo broke and I had kind of a hassle finding an "older"  ::) motherboard that would work with it, and DDR2 ram.
Having never seen the chart above, I find it interesting that blitz runs slower than gauntlet on the OPs PC. I get a lot more playability out of blitz.

As for ram, ddr2 or ddr3 won't make a huge impact on arcade gaming. None of the games are doing things that require heavy ram processing. (actually, most things on Pcs don't need that, but let's not go there.) 64bit is one of the best and easiest choices for a significant speed boost!

Has this ever been proven/disproven with actual benchmarks? If you're running the program, you're in ram, and as I understand it, for CPU intensive things like emulation, I would imagine that waiting for the ram could cause wasted cycles.

Edit: Ran a benchmark on 1942 with the above procedures on a P4 3.0Ghz machine with the same capacities of DDR226 and DDR400 with identical results. Perhaps I'm wrong, after all.

Thats not really much of a comparison between 2 speeds of ddr ram. You would want something along the lines of an AMD AM2 cpu with a built in memory controller that supports both ddr2 and ddr3.

Even then, I would still think it'd be a small difference.
