Today NVIDIA launches their updated GeForce GTX 260 Series. The new cards feature an increased shader count of 216 versus 192 on the "normal" GTX 260. Yet there is no new product name by NVIDIA, the product is still called GTX 260. I am not sure if this is a good move because it will create a lot of confusion with the users. Calling it GTX 270 or even GTX 260+ would have been a better strategy in my opinion.
As confirmed by NVIDIA this is the same GPU as on the GTX 260 and GTX 280, just with a different number of shaders and texture units. The silicon has remained the same, which means it is still a 65 nm design - a shrinked 55 nm version will follow later this year. Also it should be noted that this 216 shader GPU will not completely replace the GTX 260 with 192 shaders. There will just be three GT200 based products in the future.
