Next generation GeForce 8000-series mid-range details emerge

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

G86 and G84 (G8x family) GPUs do have some major differences between G73 however.  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.

One of the bigger surprises of the G8x family is the support for more than 4 GPUs, at least in the design.  It seems pointless to put a low or mid range GPU into SLI mode when a high-end card can usually produce better performance at lower cost.  However, the G8x family design kit touts an interface for "more than 4 GPUs."  Given the unified shader architecture of the GeForce 8000 family, it would be pretty safe to say this additional functionality is probably reserved for some sort of physics project.

The G86 and G84 GPUs are expected to launch before Cebit 2007 this March.

Which is a good time to mention that there's also rumors that the 8600 series is in fact 128-bit and that the 256-bit rumors are false.

My sources say that only the 8600 Ultra is 256-Bit, the rest are still 128-bit:

quote:
8600 Ultra: 64 SP, core 500 MHz, memory 1400 MHz, 512 MB, 256-bit, $179
8600 GT: 48 SP, core 350 MHz, memory 1200 MHz, 256 MB, 128-bit, $149
8300 GT: 32 SP, core 500 MHz, memory 1200 MHz, 256 MB, 128-bit, $99
8300 GS: 24 SP, core 500 MHz, memory 1000 MHz, 256 MB, 128-bit, $79


I first posted these specs back in this article:

I cannot fit the 8800 series cards in my Silverstone LC16-M case, and i need a DX10 part that is significantly faster than my current XFX 7950GT.

I first posted these specs back in this article:

I don't get it, should i express gratitude for you posting these specs 3 days ago? or you wish to have the "1st post award" in specs category?

enlight me please

That was meant to imply that I have a source who posted earlier other specs, while now (later) the specs may be different.

well it better be 256bit, its about time.

128bit is old, my 9500pro is 128bit and i bought that eons ago.

if nvidia dont do it, i'd imagine ATi will. they've already jumped ship to 512bit on their top end card, i see no reason why they wont chop that in half for their mid range cards (X2600 or whatever it will be called)

Nvidia too have also jumped up to 384bit, so id be suprised to see no similar progress on the mid range
