Nvidia Next-Gen Kepler GPUs Slated for Q2 2012
Nvidia's first Kepler graphics cards are now believed to be available in March or April of next year.
Japanese site 4Gamer.net reports that the entry-level GK107 card could be the first model of Nvidia's new 28 nm GPU series and arrive with a 128-bit memory interface as well as GDDR5 memory. The GK106 will follow as a mainstream version and apparently use the same GPU core, but support a 256-bit interface as well as PCI Express 3.0, instead of PCIe 2.0 in the GK107.
A performance version GK104 is due in Q3 and will use a 384-bit memory interface and integrate 1.5 GB of memory. According to 4Gamer.net, the card will deliver a single-precision floating point performance of 2 TFlops. A high-end GK110 apparently scheduled for Q4 uses two GK104 cores and deliver about 4 TFlops while the flagship model GK112 isn't scheduled to be released before 2013 and arrive with a 512-bit GDDR5 interface.
Nvidia declined to confirm the information published by 4Gamer.net.
