Gigabyte Motherboard Enthusiasts, can you clarify something for me?

How is the GIGABYTE GA-MA78GM-US2H different from the GIGABYTE GA-MA78GPM-UD2H?


The Gigabyte "comparison" feature on the manufacturer's site doesn't do a great job and resellers don't either, but then again I'm a novice so I could have missed it!

I think the only difference may be the GA-MA78GPM-UD2H has Built-in 128MB DDR3 1066/ 1333(OC)MHz SidePort Memory whereas the GA-MA78GM-US2H has no onboard memory.

Is that a correct assumption?

Also, If passing blu-ray audio and video to a receiver through the HDMI, how much will 128MB DDR side board memory help me?

I chose these two boards for my low power consumption HTPC build because I had to have a microATX form factor, wanted a MB with onboard HDMI and wanted to use an AMD 45 watt chip. If I'm missing a board or a good Intel opportunity that fits these parameters, I'd welcome the suggestions.

Many thanks!

Both boards have the Ultra Durable 3 Technology as can be clearly seen on the box covers at Newegg.com.

This however is a board/copper thickness feature both have, but it does not address the specific questions I was asking.

Thanks anyway however.

Oh yeah, side port means the onboard video has its own ram, therefore does not need to share system memory. So like I said, that's the one you wanna get.
