GF2 GTS = Nv15....GF2 Ultra = Nv16?

[megadrive0088]

if is GeForce2 Ultra actually Nv16, are their any physical differences from NV15, other than core/memory clockspeed?

AFAIK, the GF2 Ultra is simply an overclocked NV15. No physical differences, beside maybe the PCB, don't know about that.

The process was different. It was an 0.25µ "improved" process (I think it has more layers).

It was the first NVIDIA card with 64 Mo.

Its PCB is different from the GeForce2 GTS.

I think it was the more expensive non-pro graphic card ever build! I still have one somewhere in the historical box (which lacks of a V5 6000 )

Well, wasn't it decided "improved" simply meant more mature and more selective picking?
Also, are you sure it's 0.25µ? I seem to remember it was 0.18µ, as was the GeForce 2 GTS.


What's the PCB differences, exactly?

TNT - 0.35µ
TNT2 - 0.25µ
GF1 - 0.21µ
GF2 - 0.18µ
GF3-4 - 0.15µ

Also 64MB GF2's were available before the Ultra

You're right. It's 0.18µ. Memory problems

I remember NVIDIA saying me "We use an improved process form TSMC" at ECTS in 2000.

For the PCB : the first GTS reference design used 32 bits memory chips and the ultra PCB used 16 bits memory chips. The Ultra PCB was longer.

I'm not on my 'work' computer and I don't have my old articles/pictures here. But google is a great help :

Someone at NVnews's forums referred to the GF2 Ultra as "NV15BR (Blade Runner)", though I don't know what s/he meant by that.

Hmm, yeah, I think the drivers do refer to it as NV15BR. No idea why, though, nVidia codenames are often evyl and illogical

It was the first NVIDIA card with 64 Mo.

The GTS was launched in 32 and 64 MB versions before the Ultra...

Edit: Oops Hyp-X got there first

 

[breez]

I believe there was 64MB version of GeForce256 before GF2.

its the codename. just look in the inf file from a driver

NVidia.Nv15 = "NVIDIA GeForce2 GTS/GeForce2 Pro"
NVidia.Nv15DDR = "NVIDIA GeForce2 Ti"
NVidia.Nv15BR = "NVIDIA GeForce2 Ultra"

(in a newer Det. it'S been renamed:
NVIDIA_NV15.DEV_0150.1 = "NVIDIA GeForce2 GTS/GeForce2 Pro"
NVIDIA_NV15.DEV_0151.1 = "NVIDIA GeForce2 Ti"
NVIDIA_NV15.DEV_0152.1 = "NVIDIA GeForce2 Ultra"
but its still a NV15 there

hey thanks for all this wealth of info. glad i asked here on Beyond3D, instead of say, the Nvidia newsgroup, where i would have probably got
something like "i don't know the answer to the question, but....blah blah"
