The GeForce GTX 780 Ti Engineering Sample was a graphics card by NVIDIA, that was never released. Built on the 28 nm process, and based on the GK180 graphics processor, in its GK180-425-A1 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 GK180 graphics processor is a large chip with a die area of 561 mm² and 7,080 million transistors. It features 2880 shading units, 240 texture mapping units, and 48 ROPs. NVIDIA has paired 3,072 MB GDDR5 memory with the GeForce GTX 780 Ti Engineering Sample, which are connected using a 384-bit memory interface. The GPU is operating at a frequency of 875 MHz, which can be boosted up to 928 MHz, memory is running at 1753 MHz (7 Gbps effective).
Being a dual-slot card, the NVIDIA GeForce GTX 780 Ti Engineering Sample draws power from 1x 6-pin + 1x 8-pin power connector, with power draw rated at 250 W maximum. Display outputs include: 2x DVI, 1x HDMI 1.4a, 1x DisplayPort 1.2. GeForce GTX 780 Ti Engineering Sample is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card's dimensions are 267 mm x 111 mm x 38 mm, and it features a dual-slot cooling solution.

GK180 GPU Notes

NVENC: 1st Gen
NVDEC: 1st Gen
PureVideo HD: VP5
VDPAU: Feature Set D

L1 Cache is configurable from 16 KB up to 48 KB per SMX

GK180 has 5 GPCs each capable of 8 pixels per clock. This limits complete GPU to 40 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.)
