GTX 670 Ti features new technology, which is automatic overclocking called Speed Boost. It is similar to software overclocking, when card switches its profiles 2D/Low3D/3D based on computing power required. This time it will be fully hardware technology. Long story short, GTX 680 will automatically scale clocks according to demand.
Card is based on 1536 CUDA cores, it will support 2GB of GDDR5 memory on 256-bit interface. For more detailed specifications click here. Later this year NVIDIA will launch second variant of GeForce GTX 670 Ti with 4GB of memory. It is officially 28nm GK104 core.
