NVIDIA officially announced the ultra-premium GeForce
GTX 690 dual-GPU graphics card at the NVIDA Gaming
Festival 2012 in Shanghai, China.
The new video card is powered by dual 28-nanometer
Kepler architecture-based GeForce GPUs (GK104) and
features an exterior frame made from trivalent
chromium-plated aluminum for greater durability, a new
fan housing made from a thixomolded magnesium alloy for
better heat dissipation along with a more efficent
cooling system based on dual vapor chambers.
The GTX 690 is powered by a total of 3,072 NVIDIA CUDA
cores and has been designed for the discriminating gamer
and ultra-high-resolution, multimonitor NVIDIA Surround
configurations. Nvidia claims that the GTX 690 delivers
close to double the frame rates of the closest single
GPU product, the GTX 680. Plus, it is more power
efficient and quieter when compared to systems equipped
with two GTX 680 cards running in NVIDIA SLI
configuration.
The GTX 690 features two fully enabled GK104 GPUs (1536
CUDA cores) clocked at 915MHz, paired with 4GB of 6GHz
GDDR5 (2GB per GPU) all on a single card. The GPU boost
target will be 1019MHz.

As for power consumption, NVIDIA is designing the GTX
690 around a 300W TDP, with a typical board power of
263W.
The card is equipped with 2 8-pin PCIe power sockets,
enabling the card to draw up to 375W, 75W over its
standard 300W TDP. Delivering that power will be 10
power phases, so the GTX 690 will have power delivery
capabilities nearly identical to the GTX 680.
The NVIDIA GeForce GTX 690 GPU will be available in
limited quantities starting May 3, 2012, with wider
availability by May 7, 2012 from NVIDIA's add-in card
partners. Expected pricing is $999, which is double the
price of the GTX 680.
