I really wish they would just make it bigger and use a desktop card.
Unfortunately, this would require far more space and heftier thermal dissipation methods, just turning the machine into a headless Apple "desktop," which will probably not happen.
I'd settle for HD4000 integrated graphics.
The base Mini will probably stick with HD4000 graphics. Hopefully it's the BTO options which will see a nice, solid GPU bump.
7770M Anyone? Sorry, but Nvidia's OpenCL production in their chips are garbage--something Apple creating OpenCL is heavily committed to seeing win out.
Interesting. On many benchmarks, the 650m and 7770m come out almost evenly. If AMD's chips are better for OpenCL, that'd be fine with me. I'm just exasperated by the anemic 6630m and thought the current use of 650m GPUs in the MacBook Pro line might make them attractive.
Two new Gpus were released some days ago in October,
the 625m and the 645m...
i fear we will see
MacMini L Dual core Hd4000
MacMini H Dual core plus 625m
MacMini Server Quad
God, I hope your fears don't come true

. It's almost a given that any low-end Mac Mini will keep a dual-core CPU and HD4000. The 645m is not a terrible option compared to the 650m, but it still looks to be about 8-10% slower across the board. A 625m would be useless; it doesn't even have GDDR5 support.
I would pay $800 for a 2.1GHz quad-core 2630QM-equivalent (or the 2.3GHz 3615QM which is already in MacBook Pros) and an Nvidia 650m w/ 512MB GDDR5 or an AMD 7770m w/ 512MB GDDR5, 640GB 2.5" HDD, and 4GB base RAM. After the removal of the optical drive, there's plenty of space to handle thermal dissipation. Granted, this sounds like a pipe dream even to me. But I would not hesitate for a second to pick up a Mini with these specs.
Even more amazing would be an option for a 128GB SSD on the base model in lieu of an HDD. 2.5" 500GB HDDs and 128GB SSDs are almost equal in price. Or dual 256GB SSDs in RAID0 for $500? That would be glorious.
