Additional characteristics of Tesla 20 video cards
It's no secret that the first swallows of NVIDIA, which will be based on the new architecture of Fermi, will be exactly the professional solutions called Tesla 20.
Finally, it became known that they will be:
')
Tesla 20 will not receive 512 stream processors, as originally planned, but only 448. The frequency of the graphics chip will be from 1.25 to 1.4GHz, which is slightly lower than the current devices. As a result, the maximum level of performance in double precision operations will drop from the projected 630 gigaflops to 600 gigaflops. The power supply voltage of the video chip, the dimensions of which, by the way, will be 42.5 x 42.5 mm, is at the level of 1.05V. C2050 and C2070 video cards use 3 and 6GB of GDDR5 standard memory with 384-bit access bus. In this case, the memory frequency is from 1.8 to 2.0GHz, and the bandwidth is declared at the level of 170 GB / s.
The dimensions of the 10-ply 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 provided for connecting monitors. To supply power to the video card, an additional six-pin eight-pin connectors are used. Despite the decrease in previously stated characteristics, and the use of 40-nm video chip production process, the Tesla 20 power consumption at maximum load reaches 225W.
