Just a little later this week, NVIDIA will unveil the GeForce GTX 550 Ti mainstream graphics processor (GPU), successor to GeForce GTS 450. NVIDIA partners seem to be ready with their products based on the new GPU. One of NVIDIA's largest partners, Galaxy, is even ready with a highly overclocked model with its core running at 1 GHz (900 MHz reference), and 1150 MHz (1025 MHz reference) memory speed. Galaxy's card will use the HOF (Hall of Fame) identifier, which is supposed to indicate the company's highest level of factory-overclock speeds.

Based on the 40 nm GF116 silicon, the GeForce GTX 550 Ti packs 192 CUDA cores, and a 192-bit wide GDDR5 memory interface, holding 1 GB of memory, that's right, 1 GB, not 768 MB or 1536 MB. It looks like NVIDIA will be doing a mixed density memory chip setup. We can hypothesize that four of the six chips are 1 Gbit (128 MB), amounting for 512 MB; and two 2 Gbit (256 MB), amounting for the other 512 MB. Galaxy's HOF card will use a 3+1 phase VRM to power the card, and feature a dual-slot cooler. Its display connectivity includes one each of DVI, HDMI, and DisplayPort.
