Whether will bring improvements 40nm technical process?
Data on characteristics of chips RV740 and RV790 from site AMD has allowed to understand that rise of frequency with 750 to 850 MHz in a case with chip RV790 is reached simultaneously with power rise on a kernel from 1.26 to 1.3 V.
It is hard to estimate how transition to 40 nanometers influences frequency potential of chips RV770/RV790.
The Inquirer asserts that the reason of delay of implantation of 40nm in mass production became high leaked currents. This problem was not solved and level of power consumption of the 40nm chips manufactured by TSMC hardly will essentially improve. AMD and NVIDIA plan to byu the video chips from TSMC therefore the problem will concern their production.
Nevertheless, manufacturers of video chips will welcome transition to 40 nm as it will allow to reduce kernel square. Thereby cost price lowering will be reached, and in certain cases there will be a possibility to increase quantity of functions and to lift speed.
