The GeForce GTX 560 Ti 448 was a performance graphics card by NVIDIA, launched in November 2011. Built on the 40 nm process, and based on the GF110 graphics processor, in its GF110-270-A1 variant, the card supports DirectX 11.0. The GF110 graphics processor is a large chip with a die area of 520 mm² and 3,000 million transistors. Unlike the fully unlocked GeForce GTX 580, which uses the same GPU but has all 512 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 560 Ti 448 to reach the product's target shader count. It features 448 shading units, 56 texture mapping units and 40 ROPs. NVIDIA has placed 1,280 MB GDDR5 memory on the card, which are connected using a 320-bit memory interface. The GPU is operating at a frequency of 732 MHz, memory is running at 950 MHz.
We recommend the NVIDIA GeForce GTX 560 Ti 448 for gaming with highest details at resolutions up to, and including, 1680x1050.
Being a dual-slot card, the NVIDIA GeForce GTX 560 Ti 448 draws power from 2x 6-pin power connectors, with power draw rated at 210 W maximum. Display outputs include: 2x DVI, 1x mini-HDMI. GeForce GTX 560 Ti 448 is connected to the rest of the system using a PCIe 2.0 x16 interface. The card measures 267 mm in length, and features a dual-slot cooling solution. Its price at launch was 289 US Dollars.

GF110 GPU Notes

Each Streaming Multiprocessor(SM) in the GPU architecture contains 32 SPs and 4 SFUs.

Each SP can fulfill up to two single precision operations FMA per clock.

Each SFU can fulfill up to four SF operations per clock.

The approximate ratio of operations FMA to operations SF is equal 4:1.

The theoretical shader performance in single-precision floating point operations(FMA)[FLOPSsp, GFLOPS] of the graphics card with shader count [n] and shader frequency [f, GHz], is estimated by the following: FLOPSsp f × n × 2.

Alternative formula: FLOPSsp f × m × (32 SPs × 2(FMA)). [m] - SM count.

Total Processing Power: FLOPSsp f × m × (32 SPs × 2(FMA) + 4 × 4 SFUs) or FLOPSsp f × n × 2.5.

Each SM in the GPU contains 4 texture filtering units for every texture address unit.

The complete die contains 64 texture address units and 256 texture filtering units.
