The GTX 470 has 448 CUDA cores (shader cores), and has a 320-bit wide GDDR5 memory interface. Board partners will sell these cards with 1280 MB of memory. The back of the card shows tracks for 10 memory chips (confirming the 320-bit wide memory interface), and interestingly, also lacks traces for an external display IO processor (like the NVIO2 processor on GT200 based accelerators), cutting down the overall cost of manufacturing. The card draws power from two 6-pin power connectors, and has two SLI fingers for 3-way SLI support. Its connectivity includes two DVI-D, and HDMI.
