The GeForce GTX TITAN Z was a enthusiast-class graphics card by NVIDIA, launched in May 2014. Built on the 28 nm process, and based on the GK110B graphics processor, in its GK110-350-B1 variant, the card supports DirectX 12.0. The GK110B graphics processor is a large chip with a die area of 561 mm² and 7,080 million transistors. GeForce GTX TITAN Z combines two graphics processors to increase performance. It features 2880 shading units, 240 texture mapping units and 48 ROPs per GPU. NVIDIA has placed 12,288 MB GDDR5 memory on the card, which are connected using a 384-bit memory interface per GPU (each GPU manages 6,144 MB). The GPU is operating at a frequency of 705 MHz, which can be boosted up to 876 MHz, memory is running at 1750 MHz.
Being a triple-slot card, the NVIDIA GeForce GTX TITAN Z draws power from 2x 8-pin power connectors, with power draw rated at 375 W maximum. Display outputs include: 2x DVI, 1x HDMI, 1x DisplayPort. GeForce GTX TITAN Z is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 267 mm in length, and features a triple-slot cooling solution. Its price at launch was 2999 US Dollars.

GK110B GPU Notes

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

GK110 chips have 5 Rasterizers each capable of 8 pixels per clock and are limited 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.
Luckily, additional ROPs can be used when for example MSAA is enabled (because it doesn't require additional data from rasterizers, while giving more work to ROPs).
