Galaxy GeForce GTX 550 Ti Display4 Graphics Card Pictured

Here are the first pictures of Galaxy's GeForce GTX 550 Ti Display4 graphics card, designed exclusively for Asian markets. As its name might suggest, it is a GeForce GTX 550 Ti based graphics card designed to support up to four displays. The card uses an IDT VMM 1403 display output logic chip that lets it effectively make use of the total resolution the GPU supports. The redesigned display logic supports a total resolution of 5760 x 1080. Spread across four displays, you get 1440 x 1080 per display, or spread it across three displays to get 1920 x 1080 per display. Apart from four DVI connectors, its output logic makes room for a mini-HDMI connector.

The GeForce GTX 550 Ti is aided by 1 GB of GDDR5 memory across a 192-bit wide memory interface. It is powered by a 3+1 phase VRM controlled by Galaxy's in-house G-Engine chip. The GTX 550 Ti packs 192 CUDA cores, and clock speeds of 950 MHz core, 1900 MHz CUDA cores, and 1025 MHz (4.10 GHz effective) GDDR5 memory. Galaxy also used its in-house "Glaciator" cooler, which makes use of a heat-pipe fed heatsink ventilated by a large central fan. This can can be partially detached to help clean it, and the portion of the heatsink directly underneath it. Galaxy's GTX 550 Ti Display4 is priced at RMB 999 (converts to US $157).

Keep your eye on eBay. These cards are bound to show up there.

192 bit memory interface but 1024mb of VRAM... That doesn't add up.. Shouldn't it be 1152mb VRAM?

afaik, nVidia did some modifications in the memory controller for the GTX 550 Ti, in such a way that it has three 64bit memory controllers, and each controller is controlling 2 32bit memory chips. 4 of the memory chips are 128MB in size while the remaining 2 are 256MB in size totaling 1024MB of memory at 192bit. The Raster Operators (ROP) are also tied to the memory chips, and each chip has 4 ROPs in it so in simple terms:

Note: GTX 550 Ti has 6 memory chips

Memory Controller 1 - 64bit - 128MB 32bit memory w/4 ROPs + 128MB 32bit memory w/4 ROPs
Memory Controller 2 - 64bit - 128MB 32bit memory w/4 ROPs + 128MB 32bit memory w/4 ROPs
Memory Controller 3 - 64bit - 256MB 32bit memory w/4 ROPs + 256MB 32bit memory w/4 ROPs

Total of - 192bit 1024MB memory w/ 24ROPs

In terms of memory controller, its really different from GTS 450 since it had to balance the load on the odd memory configuration, and thats up to the drivers.

correct me if i miss somethin or some errors

This would make a hell of a lot more sense if it was a 580 with 3GB RAM.
