Nvidia GTX 500 line-up continues to expand

NVIDIA GeForce GTX 500 series graphics cards will be soon updated with yet another interesting model. According to leaked information the novelty will see the light on 15th of March and will be called GeForce GTX 550 Ti. This cards is said to be based on 40nm GF116 GPU and GTX instead GTS can mean that it is diffident piece of silicon unlike GF114 (a.k.a full-fledged GF104) used for production of GTX 560.

Sources claim that GTX 550 Ti will have 1GB of GDDR5 running through a 128-bit memory bus. PCB and cooling design are similar to one of GTX 560. Regarding power design, GTX 550 Ti is said to have 3+1 phase circuit while TDP level should not exceed 110W.

Cuda core number as well as default clocks are not revealed, though it shroud be lower than of GeForce GTX 560. As this is the expected to be popular product in mid-end segment competing with AMD Radeon HD 6770 (a.k.a ATI HD 5770), we believe its price should start at around 200$.

In addition, this card was already spotted in latest 266.7x Beta drivers along with another graphic card everybody is so excited about — GeForce GTX 590 — NVIDIA’s dual-GPU solution.

• NVIDIA_DEV.1244.01 = “NVIDIA GeForce GTX 550 Ti”
• NVIDIA_DEV.1083.01 = “NVIDIA GeForce GTX 590”

The last one was first seen at CES 2011, though no exact information on detailed specification revealed from that time. However, reputable internet sources report GeForce GTX 590 to be based on GF110 GPUs each equipped with 512 Cuda Cores, 64TMUs, and 48 ROPs, supporting 1536 MB of GDDR5 over 384-bit memory bus. On the other hand, cards are limited to have TDP more than 300 Watts, therefore, final specs, inducing clocks and voltages, are subject to change.

Anyways, if my memory serves me well, the appearance of new devices in driver usually indicates that we are about a month away from the actual release!
