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.

what i would love to see is a comparison between this generation's mid range cards with last generation's high end.. But you don't usually see that

Ditto id enjoy seeing it compared against a variety of older cards stemming from the last 2 generations like 6800ultra a 7600gt and of course the high end of last generations cards 7900gtx as well as ATI's equivilent counterparts.

Considering 8800GTS often barely outperforms X1950XT/X1900XT series, I doubt 8600GT with its 350mhz gpu speeds and 48 shaders will stand a chance. The Ultra version seems to be a lot better with 64 shaders and 500mhz clocks for not much more $.

I am glad to see that mid-range cards will do away with 128 bit memory interface. Still 8800GTS 320mb for $299 (probably $250 on the market within a month or 2) could be the performance/value card for 2007.

If the G86 and G84 are pin compatible with the 7600 then the G84 and G86 would likely have a 128-bit memory interface despite the rumors of moving to 256-bit.

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:

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 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

"If the G86 and G84 are pin compatible with the 7600 then the G84 and G86 would likely have a 128-bit memory interface despite the rumors of moving to 256-bit."
From dailytech above:
"Additional dead pins have also been allocated on the G8x family for higher density memory."

If there were 'dead pins' in the G73, those could be allocated to widen the memory bus. I slightly doubt we'll see 256-bit, 192-bit would make more sense since it's half of the 384-bit the 8800GTS uses, it allows a more linear scaling in components. Yes the card designs would need more traces, but adding a few memory bus traces is probably a lot easier than redesigning the entire card, as long as the # of traces is relatively low. (Is 64-ish (Probably closer to 75 with power and etc) traces per memory chip relatively low? I don't know, but the possibility is definitely there without ruining the entire cost-savings design (Though the Ultra part does seem to me like it's going to be more expensive than people are claiming, or lower specs at that price point)

Try looking at some more applicable benchmarks.

Who buys a $400+ card to play a game at 1024x768 with no AA or AF?!

In that same benchmark @ 1600x1200, 4xAA, 8xAF, the 8800GTS beats the 1900XTX by 27FPS, or 26%.

And it beats the 1950XTX by 24FPS, or almost 24%.

Please leave your bias at the door and present only the facts. Everyone (hopefully) knows that lower resolutions prove hardly anything about graphical power.

I assume that the lower performance at lower resolutions is because of early drivers for the geforce 8800's? Or is it because the geforce 7 (Or equivilent) series is fully optimized for DX9 and the Geforce 8 series is more prepared for DX10 (Because all DX9 games run fast enough any way)?

I remember when dual core processors came out and they weren't quite as fast in games than their single core counterparts. It seemed silly going for a fast single core processor for the same reason as buying a dx9 card now- although slower, the dual cores were more future proof and would stand up better against things which would slow a single core to a crawl.
