Nvidia Unveils GTX Titan Z Dual GK110 GPU Graphics Card
Nvidia today officially released its flagship dual-GPU video card, the $3000 (!) GeForce GTX Titan Z, based on two GK110 GPUs read to fulfil the increased graphics needs of professionals and gamers. The card is shipping with its GPUs clocked at 706MHz, while the boost clock is set at 876MHz. It has 12 GB of 7 Gbps video memory, 5,760 CUDA Cores, and two GK110 GTX TITAN Black GPUs to power 3840x2160 setting gaming.

NVIDIA has configured the card with a 375W TDP, putting the TDP 50% higher than a single GTX Titan Black. This lower TDP means that while the GTX Titan Z could underperform GTX Titan Black in SLI, it should undercut the latter's power consumption.
The GTX Titan Z uses 12 power phases. Power is delivered by a pair of 8pin PCIe power sockets, which combined with the PCIe slot itself allow up to 375W to be pulled.
The card is cooled via a triple slot cooler coupled with a split-blower design. This increases the altogether the GTX Titan Z is going to take up 4 slots of space inside your PC, considering a PCI slot left empty for spacing and effective air stream.
The card's exterior is comprised entirely of aluminum, providing durability and heat dissipation.
The centrally-mounted axial fan is 40% thicker than GTX TITAN Black's, and was specially optimized with custom fin pitch and air entry angles to minimize noise and maximize cooling efficiency. At full speed, airflow peaks at 33 cubic feet per minute.
Beneath the fan, on an aluminum heat-dissipation plate placed above the VRAM, Nvidia has introduced ducted channels that improve airflow and improving acoustic qualities.
Flanking the fan are dual vapor chambers attached to 500 square inch extended fin stacks, featuring 60% more surface area than GTX TITAN Black, to draw heat away from components and towards the aluminum exterior.
Beneath sits the GTX TITAN Z's dual GK110 GTX TITAN Black GPUs, and Nvidia's 12-phase dynamic power balancing technology, which dynamically routes power to each GPU.
Finally, a black, custom NVIDIA aluminum backplate transfers heat away from the rear of the card.
The GTX Titan Z will support up to 4 displays, indicating that all I/O ports are being routed through a single GPU. NVIDIA's port configuration includes 1x DVI-I, 1x DVI-D, 1x DisplayPort, and 1x HDMI.
The GTX Titan Z is retailing at $2999, making it NVIDIA's most expensive GeForce card yet. MSI, Zotac, Asus, Gigabyte, Palit, MSI and EVGA.
Of course, $3000 is going to be a steep price to pay for GTX Titan Z, both compared to the AMD and even the NVIDIA competition. A pair of GTX Titan Blacks would run for $2000.
NVIDIA is advertising the GTX Titan Z as the ultimate compute card as well as ultimate gaming card.
NVIDIA will also face competition from AMD's recently released Radeon R9 295X2, which at $1500 retails for half the price of GTX Titan Z.
