Arstechnica has the news on this HUGE announcement. The K5000 is the replacement for the QUADRO 5000 and runs at $2249. You check it out at NVIDIA as well.
Built around NVIDIA’s latest “Kepler” architecture, the double-wide card boasts 1536 processing cores shuffling pixels at up to 173GB/s along a 256-bit path to 4GB of GDDR5 memory. The card supports Shader Model 5.0, Open GL 3.2 on Mac OS X, and Open GL 4.3 and DirectX 11 when running Windows under BootCamp. And, it can support up to four monitors: two running at 2560×1600 over dual-link DVI ports, and two running up to 4096×2160 over DisplayPort 1.2. All that power also fits within an Energy Star-rated 122W power envelope.
This has serious CUDA performance and should be awesome for Adobe Premiere Pro and DaVinci Resolve 9.
Even more exciting for us not quite able to afford such a behometh card is that it signals some changes from Apple and Drivers. As you can actually run many Kepler cards now without much effort, since they included the drivers to deal with the NVIDIA powered MacBookPro and NVIDIA has started just writing a single driver for all cards in a series instead of different drivers. The thing is as of now you can only see 2GB of RAM on a card without doing some fiddling, which is an arbitrary addition made by Apple. The 4GB of RAM in this card looks like this will soon change for the better. And hopefully we get some Kepler GeForce cards running at full power on the mac soon. Like a GeForce GTX 680 (which matches the 1536 CUDA cores of the QUADRO) with slightly higher memory bandwidth.
Any way you look at this it is good news for high end mac graphics as it looks like NVIDIA is back and here to stay.
