Features and specification
Aah yes, yet another 560 Ti GPU based graphics card to review, two of them really :)
Let's dive a little into the architecture of the GeForce GTX 560 Ti GPU, it is in fact based on the GF104 GPU (GTX 460) and it is tweaked a little to allow higher clock speeds with a presumably lower power draw. The GPU now is labeled GF114, the GeForce GTX 560 has 384 shader processor cores, 32 ROPs, and a 256-bit wide memory interface that connects to four 64-bit controllers with each 256MB memory tied to it, so that's 1 GB of memory in total per GPU partition.
Typically each reference GPU has holstered rather high GPU clock speeds, with 822 MHz core, 1644 MHz on the shader cores, and 4000 MHz (GDDR5 effective data rate) memory, chunking out a very decent 128 GB/s in memory bandwidth -- reference of course as the specs for the GTX 560 Ti 2Win differ a little:

If you look closely at the SM (Streaming Multiprocessor) partitions, then you can see the GF114 GPU has 384 shader processors, and has that last available SM cluster enabled.
The GeForce GTX 560 Ti is based on a 40nm fabrication node, has 1.95 Billion transistors and thus looks and feels like the GTX 460, yet now with 48 shader processors and accompanying PolyMorph Engine added, an extra 8 Texture units and sure, much faster clock frequencies.
All cards derived from and based on this GPU are based on a dual or even triple-slot cooling design based on what the AIB/AIC partners prefer and come with two dual-link DVIs and a mini-HDMI connector. HDMI again passes sound through, including bit streaming support for Dolby TrueHD and DTS-HD Master. Being a mid-range product, only 2-way SLI will be allowed and thus you'll only see a single SLI finger/connector on the PCBs. Okay, the next stop will be an extensive photo-shoot of today's product.
