Title: Hardware for new MAME Build (pc)
Post by: jcuticchia on December 20, 2020, 05:43:09 pm
I have spent a lot of time trying to figure this out.  I am building a MAME system and want to run things smoothly.  I will be using a LCD (32 inch) and a cabinet built to accept Xarcade Tankit.

I just can't figure what pc components to get.  I have a Nvidia 1050-2g I would like to use.  But I don't know if I need the 8/9 gen i5 to build this, or can get something less powerful.  In other words I wan't the most most modern machine to do this without overkill.

Any assistance will be more than greatly appreciated!

Hi there mate, welcome to forums.
First of all, disclaimer, I'm only building my first cab but its based on about 1 year research and intensive looking into things.

The thing to note with Mame is that its an emulation environment. You're creating a virtual machine, which means the graphics card is not used at all in the traditional sense beyond passing through the output. The CPU  *might* offload some functions but the card is not doing any rendering.
What's most important therefore is the unmber of clock cycles of your machine.
Now I don't know this bit for certain, but I suspect that say a 4ghz gen 8 core i5 may perform better than say a 3Ghz gen 10 core i7. You probably don't need the processing complexity per clock cycle at this level.
The emulation will run on a single thread, so less cores at a higher speed may benefit an emulation environment more than a higher number of more complex cores and overall lower clock speed
There may be an article out there that actually benchmarks this, but my guess is that a fast core iAnything will be hella fast, and it will all be about keeping your bckground processes lean.

In this context as well, a discrete graphics card will make minimal difference in a Mame environment. Use it if you have it, it will help, but just remember that its the CPU that will be doing the heavy lifting.

There is a very similar post that was started in the last week or so. http://forum.arcadecontrols.com/index.php/topic,164155.0.html

Short answer: fast as you can afford
