It’s not a secret that the first signs of NVIDIA, which will be based on the new Fermi architecture, will be professional solutions called Tesla 20.
Finally, it became known that they will be:
Tesla 20 will receive not 512 stream processors, as originally planned, but only 448. The frequency of the graphics chip will be from 1.25 to 1.4 GHz, which is slightly lower than the performance of modern devices. As a result, the maximum level of productivity in double-precision operations will decrease from the projected 630 gigaflops to 600 gigaflops. The supply voltage of the video chip, the dimensions of which, by the way, will be 42.5x42.5 mm, is at the level of 1.05V. C2050 and C2070 video cards use 3 and 6GB of GDDR5 memory with an access bus of 384 bits. At the same time, the memory frequency is from 1.8 to 2.0 GHz, and the throughput is claimed at the level of 170 GB / s.
The dimensions of the 10-layer printed card on which these devices are made are 111.2 x 247.7 mm. New items are also equipped with a PCI Express × 16 2.0 connection interface, and only one Dual-link DVI-I connector is designed to connect monitors. To supply power to the video card, one additional sixth of an eight-pin connector is used. Despite the decline in the previously announced characteristics, and the use of a 40-nm process technology for the production of video chips, the Tesla 20's power consumption at maximum load reaches 225W.
