Report: Nvidia GeForce GTX 285 Graphics Card Is Mac-bound

A graphics card based on Nvidia's GeForce GTX 285 chip is headed to the Mac Pro, according to tech blog Engadget. The GeForce GTX 285 is one of Nvidia's most powerful GPU designs ; it sports 240 processor cores, a 648MHz graphics clock and 1,476MHz processor clock, and is capable of a texture fill rate of 51.8 billion per second. Indeed, the GTX 285 seems to match or perform slightly better that the 4870 X2 -- a two-GPU variant of that ATI card. Neither Nvidia nor EVGA, a graphics card maker whose logo appears emblazoned on the image in Engadget's story, would confirm the news when contacted by Macworld.

AnandTech recently reviewed the PC version of the GTX 285 and found that it consistently outperformed the ATI Radeon HD 4870, whose Mac counterpart is currently available as an upgrade for the Mac Pro. NVIDIA just last week announced the upcoming Quadro FX 4800, offering a professional-level graphics card option for Mac Pro users at a price point of $1799. The GTX 285, however, should provide a significant performance boost over the current standard-level offerings for the Mac Pro at a price point closer to $400
