NVIDIA To Release Four GK106 Graphics Cards
Even though we have the exact GPU codename, memory size and memory interface we don’t know how will those GPUs differ. Most likely NVIDIA will reduce the number of CUDA cores for each iteration. We can assume that GK106 is a replacement for GF116. This predecessor was released in three versions: GF116-400, GF116-200 and just a GF116 (I hope I’m not wrong here). According to the listing there would be four iterations of GK106 with some mysterious GK106-250 version. We can assume that this GPU will be a slower version of full GK106-400 with 960 processors. I would call it a GeForce GTX 660 SE, since GK106-200 will most likely power the GTX 650 Ti (with 128-bit interface), which should be released next month. There’s also a version for workstations – GK106-875, which might be a mid-range Quadro card.
Anyway, here’s the original table and my predictions, feel free to join the rumor mill.
