Information on the first 40nm GPUs from AMD and NVIDIA
Or everything you know about the RV740 and GT216 at the moment can be guessed.
Az RV740 codenamed, the 40-nanometer graphics processor is expected to inherit the RV4670 (with a PRO or XT suffix) serving ATI Radeon HD 4650 and HD 730 video cards, but given the technical specifications ventilated by VR-Zone, this GPU It is comparable to the RV4830LE used for the 770.

Due to the more modern production technology, the production cost and consumption are lower than that of the 55 nanometer "brother" cited as an example, while its performance is certainly almost the same (the core clock signal is unknown), moreover, the presence of GDDR3 cards replacing GDDR5 memory chips is a guarantee that the RV740 -based graphics controllers will perform better in various benchmarks and gaming software. Some manufacturers associate the RV740 with GDDR2, GDDR3 or even GDDR4 type cards for certain models, the premiere of video cards built around it may take place in the second quarter of next year, the price of these VGAs is expected to remain below $100.
In the meantime, NVIDIA is not sitting idly on its laurels, in order to alleviate the "injuries" suffered recently, the engineers of the Santa Clara company are working hard on the GT216, which promises to be the company’s first 40-nanometer graphics core. Expreview reportedly associates the GPU with (effective) 2,4 GHz GDDR192 chips communicating on a 3-bit memory bus with NVIDIA - total capacity of 384 or 768 MB. As for the number of shading units, speculation has started, according to Expreview's ideas, in the case of the GT216 we can talk about 7 TPC (Texture Processing Cluster), which contains 24 shades, so in their writing they voted for 168 SP.
