NVIDIA is working on the GeForce GTX 550 Ti (and not the GeForce GTS 550), a new GF116 based graphics card that is expected to hit retail shelves on March 15th. According to leaked details seen by VR-Zone, this new model will be up to 35 percent faster than AMD's Radeon HD 5770 in DirectX 11, and about 20 percent faster in DirectX 10.
The GeForce GTX 550 Ti will have a 64-bit memory controller, up to 1GB GDDR5 memory, and a PCB board similar to the GeForce GTS 450 with a 3-phase VRM for the core and single-phase for the memory. TDP is expected to be no more than 110W and display outputs will include dual-link DVI-I and one Mini-HDMI port. Cooling will be provided by the same sunflower-like cooler as on the GeForce GTS 450, and while an official price is still unknown, it may be somewhere around $200.
