Will the current MAME work with this?
lettuce:
Apparently the intel chips that have the HD3000 iGPU in them can handle mame WITH HLSL enabled (bar 1 or 2 games) at full speed. So the HD4000 should handle anything mame can throw at it even more if your not using HLSL
vimfuego:
Do you guys know how well these HD3000, HD4000 etc GPU's work with standard resolutions? Eg 456 x 336 @ 15.72 KHz.
And is this resolution/sync freq really only an issue with CRT monitors? I'm not sure I want to go with LCD because I know they can look nasty when not in their native resolution but I'm thinking there needs to be some compromise with all this.

You're sort-of misquoting me from that previous thread. To be specific: the i5-2500K can handle all of currently-playable MAME games at 100% ... CPUs below level that are pressing your luck. MAME is primarily dependent on CPU power, the GPU is mostly only used to render the HLSL effects. That includes the 3D games like Tekken, etc. It just so happens that the 2500K has just enough grunt to do it, and the HLSL is a nice bonus. If you bought an i3-3225, for example, sure it has the HD4000 iGPU, but it's only a dual-core CPU ... that's going to choke and die a horrible death when it tries to run NFL Blitz. :laugh2:
Now, like I said in your other thread, the 2500K does have some difficulty with dual/multi-monitor games specifically and only with HLSL enabled (Punch-out, Darius, etc.) but that MAY be just the way MAME implements HLSL, and/or the integrated iGPU not having enough power to handle it. I have no way to test a higher spec CPU at this moment.

Now this I have been very curious about... the Intel driver configuration utility has an area where you can create custom resolutions, but I have no way of testing it with an arcade CRT. My guess, however, is that if the HD3000 series (or better) could handle and output arcade resolutions properly, we would have already heard from someone else in the community by now. I think it'd be a pretty big deal. Surely I'm not the only one here running an i5! ;D
Wait a month, get a nice Haswell that can run 3.3 ghz or better across all 4 cores in Turbo mode (see charts here for previous i5 examples) and run HLSL, and you'll be running everything MAME can currently run, fine and dandy, on an LCD screen. That's my 2 cents.

To be fair both have a retail clock of 3.3ghz and seeing as MAME doesn't utilise more than 2 cores then there should be any performance gain over an i3 or i5 at the same clock

Apparently, that's also no longer true. It does indeed utilize all four cores of my 2500K - quite heavily in the case of NFL Blitz (to 70~85% load across all cores.) I don't know for certain when that changed, or what the criteria is for Mame to do so, but I believe Haze also mentioned that it does utilize more than 2 cores now in some cases.
EDIT for clarity and spelling.
