NVIDIA announced yesterday the GeForce 9400 and 9300 motherboard GPUs which offer desktop equivalents to the NVIDIA mobile chips adopted by Apple in their new notebooks:
These new mGPUs give NVIDIA a big advantage over other integrated graphics chips, said Dr. Jon Peddie of Jon Peddie Research. By doing so much parallel processing on a single chip, they can accelerate the new visual computing applications people are getting, and at a reasonable price. The GeForce 9400 and 9300 mGPUs set a new standard for what users should expect from todays more mainstream desktop systems.
It's not clear if this technology would find any use in future Apple Macs. Apple has traditionally based their iMac around the same chips and technology that power their notebook computers, while using server-class technology in their Mac Pros. In the past, Apple has not used Intel's "desktop" offerings.
