Sources in the hardware industry leaked some interesting pictures of a new, supposedly reference-design NVIDIA GF100 GPU graphics card PCB, watermarked by board partner Little Tiger. The pictures reveal a PCB that's similar to that of the GeForce GTX 480, but with a stronger VRM that makes use of better high-C surface-mount capacitors (completely doing away with cylindrical capacitors), and draws power from two 8-pin PCI-Express power inputs. The design can deliver up to 375W of power (that's not the board power we're talking about).

This also opens up speculation about what NVIDIA would do with this design. The most talked about theory as of now points to a new high-end SKU by NVIDIA based on the GF100, that enables all streaming multiprocessors (SMs) physically present on the GF100, taking the CUDA core count up to 512, and ROP count to 64. The most likely marketing name for this SKU is GeForce GTX 485. Apart from higher CUDA core and ROP count than that of the GTX 480, slightly higher clock-speeds for the GPU are also on the cards. The memory subsystem remains untouched, at 1536 MB of GDDR5 memory clocked at 924 MHz (effective 3.7 GHz), over a 384-bit wide memory interface. NVIDIA could release this SKU this fall.

Just hope it doesnt come TOO soon. Just spent 1600BRL for the gtx 480.

512bit would normally mean 1GB (ie GTX285) or 2GB of Memory !

lol it will need even more power than the 480 looking at the 2x 8 pin power plugs.

Not sure if I buy it, but the upgraded vrm circuitry seems to jive with somewhat consistent reports of this being a weak link on current gen 480s.

The PCB design looks too neatly arrainged, plus there is no hole for additional airflow, tentatively I think we're looking at a non-reference GTX480.

the PCB still in testing stages they don't add hole to testing samples

There is no place to put a hole in the pcb. Also your opening post says the ROP will change to 64, but the chart shows it at 48, the same as a GTX 480. The TMUs change from 60 to 64, maybe that's what you meant?

Better cooler with bigger fan instead of going the ATI route (like 480) with a smaller louder Delta !

Like I said in a previous post, make the (Power Bulge lol) like a 8800 Ultra and use that extra outer space to fit a bigger/quieter fan (I know the 8800 Ultra did not make use of extra space though).

Also be glad to see back of tall cylinder type caps that can break if you are in and out case a lot.
 
Also more pins for power does not mean it needs more power, it could be cleaner supply like modern Mobo's use and after all 1 is always for the fan only (4pin on a 285 only powers the fan, the other 6pin+PCI-E slot powers the GPU.

There was nothing to figure out as it was no big mystery that the yields for both ATI then Nvidia were crap from TSM.

This is old "news", its not a GTX 485, its a non-reference GTX 480.

Here's the original story back from March 30, 2010 from Expreview with CAD drawings of the PCB: http://translate.google.com/translate?js=y&prev=_t&hl=nl&ie=UTF-8&layout=1&eotf=1&u=http%3A%2F%2Fexpreview.com%2F9967.html&sl=zh-CN&tl=en

At the top of that story you'll notice an ad and link to Little Tiger's website clearly denoting a GTX 480: http://www.fbykj.com/

And if you follow the GTX 480 non-reference link you'll see a blog post of some sort detailing the non-reference GTX 480: http://www.fbykj.com/zhuanti/gtx480/gtx480.html

You'll see "GTX 480" mentioned numerous times in all of those links, but no mention whatsoever of "GTX 485". 

ether way its better and faster than a normal 480

seems that someone from Fudzilla was hunting around here for news lol
