More details have surfaced in relation to NVIDIA's next-gen mid-range graphics card lineup (currently dubbed (G86 and G84), its been discovered that the PCB design for these cards continues to be almost identical to previous-gen cards (back to the days of NV40), though there are apparently a few major differences between them and the current G73 based cards, For starters, the main G73 power rails run at 2.5V -- on the G84/G86 these rails run at 1.2V and 1.8V. The G73 clock generator runs at 1.3V while the G8x family clock generator runs at 3.3V. Additional dead pins have also been allocated on the G8x family for higher density memory.
The Dailytech have all the info.
The GeForce 7600 and 7300 became readily-available, affordable video cards almost overnight. A major secret to the success of these cards was due to the fact that the GPUs were designed to use the old PCB designs from GeForce 6200 and 6600. Once again, NVIDIA will take advantage of this mentality again with the next generation G86 and G84 video cards scheduled for release this quarter.
Was it surprising that images of the GeForce 8600 that have been "leaked" out to the internet look identical to GeForce 7600s, or for that matter GeForce 6600s? It shouldn't be, as that was sort of the whole point in making G84 and G86 pin compatible with G73, which was already pin compatible with NV40.
