se così fosse, un 420 a 12 pipelines reali ed il 423 a 16... sarebbero
enormemente avvantaggiati...
voci danno per uscente il 423 poco dopo l'nv40 ed il 420 (che sarebbe poi un
423 con un quad pipe disattivato aka 9500 mod) in contemporanea..

In the last part of our CeBIT report by us the rumor was brought in
circulation that itself the R420 and the R423 not only in the used I/O
interface (R420: AGP, R423: PCI express would differentiate), but that the
R423 besides 16 pipelines have could, while the R420 would have to get along
with their 12. To this topic we received now again something different one,
more precise information: So both the R420, as well as the R423 have
theoretisch(!) 16 pipelines, it depends however on the Yields whether also
all this are used. For the moment it points more on the fact that ATi will
bring the chip to 4 pipelines in favor of a better yield according to
standard a Quad block, thus, to deactivate and with 12 Pipes on the market.
If it should require the situation, the enterprise could the best chips
probably still read out and as 16-Pipeline Design on a "Ultra" board block.
Further rumor: The R500 comes possibly in former times, when so far one
accepted. Probably one does not even want to leave the point place in the
own Lineup to more for a whole year of the old R3xx/4xx-Architektur. This
covers itself with our information that the development of the R500
progressed already very far.

Oggi anche l'Inquirer ritorna sull'ipotesi 16 pipeline:
What Nvidia said more then once to its loyal NDA (non disclosure agreement)
press is that its chip uses 16x1, 32x0 approach. This is why all of them
have the general feeling that Nvidia will win this round of the graphics
wars.
This means that Nvidia can officially claim that its NV40 chip has 16
pipelines that can process one texture per clock which would pretty much
mean that it will beat the R420 12x1 design.
Nvidia also claims as much as 32x0, perhaps producing the ability of the
NV40 to render pixels without Color or Z value that will be very important
in Doom 3 and games that use this engine.
I just cannot figure how you can put 16 real pipelines in a chip that is
around 70 per cent bigger than the NV30 which eventually had only 4x2
marchitecture. A 70 per cent larger die implies that you could double your
pipeline count but not quad it.
(Nota: R300 č poco piů di 110 Ml trans. ed č 8x1, per cui non mi sembra
impossibile un 16x1 con 210 Ml., una volta eliminate tutte le parti
ridondanti di NV30).

Insomma, nVidia dice 16 e l'Inquirer dice 8. Vedremo fra poco chi ne sa di
piů ;-)
Ciao,

 più ;-)
leggo anche....
NV30 taught me to be sceptical about Nvidia claims since our developer
friends could easily find out how many textures you get each pass, not a
hard thing to do.
ti ricordo che nvidia ha anche detto che nv30 era un 8x1 invece son stati
pesantemente sbugiardati: era un 4x2
francamente hanno attendibilità zero..
parrebbe che invece si tratti di un 8x2 in grado in alcuni casi di
comportarsi come un 16x1 il che è *profondamente* diverso, 423 parrebbe (il
condizionale è d'obbligo in questi casi) un 16x1 reale..
insomma vedremo ma ho più di un dubbio a riguardo.. il 13 aprile sapremo
tutto (saranno consegnate 7 nv40 ad altrettanti vincitori)
