My next bet is that ATI might hit back with a Mac & PC version of the new HD 4770. For one thing the GT200 GPU can now do 64-bit double precision floats, useful for OpenCL, just as ATI HD3xxx and HD4xxx GPUs can do. I guess they were just waiting on the drivers since the GT200 GPU is quite distinct from the previous 8xxx and 9xxx series. I always wondered why Apple didn't choose 1GB for their HD4870, but if the intention was always to eventually have the 1GB GTX 285, it makes sense now. This will only get more common with OpenCL applications and it shouldn't be necessary to go all the way to a Quadro to get more than 512MB of VRAM. Certain GPU accelerated applications like Mudbox already complain of insufficient memory with a 512MB GPU. Although if nVidia prices it aggressively, say at $400, which still allows them a $50 premium over the PC version, the GTX 285 could seriously undercut the HD4870.Īnd having a consumer GPU with 1GB is very useful. At the same time, with the Mac version of the 512MB HD4870 priced at $350 up from $150 on PC, I'd hate to see what price the GTX 285 will have. While at $350 for the PC version, the GTX 285 is definitely a high-end GPU. ![]() ![]() ![]() I think this is great news, because while the 512MB HD4870 is a great GPU, with a MSRP of $150 for the PC version, it's a mid-range part. Appleinsider reports that nVidia has told them that a GTX 285 Mac Edition is coming and will be produced by EVGA.
