NVidia Launch GeForce GTX 660 Ti
Nvidia today launched the GeForce GTX 660 Ti graphics card, the third in their line-up of GK104 based cards. Similar to the GTX 670, the reference specs differ only in the memory bus width, and hence bandwidth. The specs at NVidia also indicate this to be one of the first cards to support the new OpenGL 4.3 spec, launched on August 6th of this year.
With 1344 CUDA cores, running at a base clock of 915 MHz with a boosted clock of 980 MHz, the card has texture fill rate 102.5 GigaTexels/s. The standard memory configuration includes 2 GB of GDDR5 memory, clocked at 1500 MHz, giving an effective memory clock of 6 GHz on a 192-bit interface. The memory bandwidth is 144.2 GB/s. This means that applications and games, which rely on a high bandwidth, will be slower than when run on a GTX 670. Those applications, which rely more on the GPU clock, will run almost as fast as on the higher spec cards.
Other features include OpenGL 4.3 support (as mentioned above) along with standard features, such as PCI-E 3.0, DirectX 11, CUDA and OpenCL. NVidia standard features include 3D Vision, PhysX and GPU Boost. The standard design cards will support up to 4 independent monitors, 3 of which can be grouped together to produce a resolution of 5760 x 1080 (that's 3 x 1080p resolution). GTX 660 Ti also supports up to 3 cards in SLI mode.
The standard card has 1 x Dual Link DVI-I, 1 x Dual Link DVI-D, 1 x HDMI and 1 x DisplayPort outputs. The reference design has an 9.5 inches long PCB, making it the same size as GTX 670 reference cards. The card draws a maximum of 150W, and has 2 x 6-pin PCI-E power connections, allowing for a decent overclock (this gives a maximum possible power input of 225 W).
Cards from most AIB manufacturers are available in the retail market from today, with an MSRP of $299.
