RV740, the first GPU built by AMD on the 40nm silicon fabrication process, seems to be gaining attention. While earlier reports suggested this core to be simply a miniaturized RV730, a fresh report emerging from VR-Zone says otherwise.
The RV740 is supposed to be largely derived from the RV770, as in its RV770LE avatar which went into making the ATI Radeon HD 4830. There are some interesting specifications attached to it. To begin with, the core physically holds only 640 stream processors, in comparison to the 800(+) on the RV770. The core continues to have 32 texture memory units (TMUs) and 16 render back-ends. Interestingly, there is a 128-bit wide GDDR5 memory bus instead of 256-bit wide GDDR3 (for the RV770LE). With this, the RV740 has a rated memory bandwidth identical to that of the RV770LE, 57.6 GB/s, though the bus width would warrant the use of lesser number of memory chips, and effectively reduce manufacturing costs. Graphics cards based on this GPU are expected to emerge in early 2009. You can also expect derivatives based on this core with GDDR4, GDDR3 or even DDR2 memory. In any case, the products are expected to cost below US $100.
