A 175M part definitively did tape-out; whether it was ever meant for retail avaibility, I've got no clue though. And there also were designs of a 150M NV40; again, whether this part was just experimental or not, I've got no clue.

Then what are the differences between these revisions besides the trans count?
At around 400 mm², this thing's larger than Gallatin4M!anaqer said:V3 said:Anyone with the know how to estimate the size of the chip from those pics ?
I'd guesstimate the die size to be roughly 20-by-20 or even 22-by-22.
When looking at the AGP 1.0 specs, the length from pin 1 to pin 58 is 68.68mm. Then the core would be about 20mm wide. The height shoud be around 10% smaller, so thats about 18mm.V3 said:Anyone with the know how to estimate the size of the chip from those pics ?

incurable, wondering about the loss nVidia'll take per card sold.
Judging from those lines, it'll employ an NV38-style cooler, probably using a refined heatsink on the core itself.Guden Oden said:MuFu:
Look at the silk screen lines on the image just a little above your post... Jesus, that'll be some heatsink/fan combo!! The fan/blower looks to be of at least Radeon 9800XT dimensions, wonder if it'll be two slots high too? If so, it'll make some major racket I guess.

I only see the standard NV38 outlines (pictures of the NV38 cooling assembly at http://www.digit-life.com/articles2/gffx/nv38-36.html/nv38-36.html), though CoolFX aint deviating much from it anyway.MuFu said:That PCB is screened for a HS+fan and Gainward/Innovatek CoolFX I reckon.
Richthofen said:you can be sure that they won't take a loss. Prices of high end parts are rather high. There is always enough headroom to compensate the one or another cost factor.
Nvidia's management predicts that margins will improve on the NV4x line compared to NV3x.
Even after the introduction of a rather complex FX5900XT sold in the mainstream price range Nvidia managed to improve their margins.
In this case i think 2004 will be a lot better for them even if NV40 has 16 pipelines.
Wasn't there talk of nVidia artificially increasing the die size on some cores to improve heat transfer to the heatsink? Is that even a viable option?incurable said:At around 400 mm², this thing's larger than Gallatin4M!anaqer said:V3 said:Anyone with the know how to estimate the size of the chip from those pics ?

It is been manufactured in the East-Fishkill FAB at IBM, not at TSMC. Also that sample board (A01) has 500MHZ GDDR3 (K4J55323QF-GC20), which either is just a very early sample, or this card resembles the non-ultra version.WaltC said:Well, if they can go from poor-to-below average yields on .13 nV35/38's with 4 pixel pipelines in 2003 from both TMSC and IBM, to good-to-excellent yields on a .13 nV40 with 16 pixel pipelines in 2004 from TSMC, they'll deserve whatever success they can get, and my hat's off to 'em...
