The GeForce GTX 480 Core 512 was a graphics card by NVIDIA, that was never released. Built on the 40 nm process, and based on the GF100 graphics processor, in its GF100-ES-DT1-A2 variant, the card supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. The GF100 graphics processor is a large chip with a die area of 529 mm² and 3,100 million transistors. It features 512 shading units, 64 texture mapping units, and 48 ROPs. NVIDIA has paired 1,536 MB GDDR5 memory with the GeForce GTX 480 Core 512, which are connected using a 384-bit memory interface. The GPU is operating at a frequency of 527 MHz, memory is running at 700 MHz (2.8 Gbps effective). Being a dual-slot card, the NVIDIA GeForce GTX 480 Core 512 draws power from 2x 8-pin power connectors, with power draw rated at 375 W maximum. Display outputs include: 2x DVI, 1x mini-HDMI 1.3a. GeForce GTX 480 Core 512 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 292 mm in length, and features a dual-slot cooling solution.

GF100 GPU Notes
PureVideo HD: VP4
VDPAU: Feature Set C
GF100 has 4 GPCs each capable of 8 pixels per clock. This limits complete GPU to 32 pixels per clock and because of that it can't feed all 48 ROPs when they all require data at the same time.
Additional ROPs however can be used for MSAA (because it doesn't require additional data from rasterizers, while giving more work to ROPs.)
