From a Manufacturing standpoint, having a single GPU would be better for them. It runs cooler (usually), uses less power (again usually), and thus in the end would end up saving them money on cooling and such.
I think you are missing some key points:
1) A less complex gpu has higher yields which MORE than offset cooling costs. Compared to wasted wafer space and # of working gpus one can pump out of a 300mm wafer, cooling costs of a gpu are practically immaterial. Think about.
2) A less complex gpu requires lower R&D spend and possibly less respins to get the bugs out/appropriate frequency, etc. There is absolutely no question that it's a lot more risky from a manufacturing and business perspective to attempt to design a large monolithic core that will be outperform the competition.
- you have issues of downscaling those cores to smaller ones while when you have a mid-range gpu, you just package them together (software becomes the scaling problem)
- what happens if your gpu doesn't outperform the competition? We know how this worked out for HD 2900XT...
3) A dual-gpu card will not necessarily run any hotter or use any more power than a large die gpu like GTX 280.
In other news,
"The Radeon 4850 features a 625 MHz core clock and GDDR3 clock in excess of 2000MHz.
Corporate documentation explains that the 480 stream processors on the RV770 processor offer considerable enhancements over the 320 stream processors found in the RV670 core, though AMD memos reveal little about how this is accomplished. "
So much for 800 shaders.........
