nv40 41 and 45 info

How can you say that, if we actually don't know anything about the two upcoming cards? Especially there isn't any real info about R420 floating around.

Never in history both companys had so similar hardware, very interesting indeed :eek:
Or cheats...

Who here honestly thinks NV will remove any cheats that still benefit them anytime soon...even if their card performs decently without them.

Looks like AA is being improved as suggested earlier so that is a very good if it happens.

where's the NV45 (and NV41) info? i only see NV40 info/speculation.

Nothing really new from 3dcenter, they basically repeat what Uttar and MuFu had revealed months ago, see the olders threads in this forum. :p

And shouldn't NV41 be the mainstream chip ala NV31/36? May be Uttar's and MuFu's sources are equal to ours at 3dc, but we don't refered to or rely on statements of Uttar or MuFu or other forum-users.

can someone explain what 16 z stencils tests per clock means and what it is in relation to what we have in nv3x and r3XX serias R300 and NV30/35/38 can apply 8 z/stencil-tests per clock. Z is the value of the depth of the (sub-)pixel, Stencil is a value used for some special effects like some kinds of lighting or shadowing, or masking some areas out. Some sophisticated engines needs a "Z-first-pass" for a correct rendered image, so a high "z-fillrate" comes in handy to speed up the rendering. This gets even better with use of the "early-z"-feature, after the z-information is calculated, invisible pixels can be excluded from the rendering.

Rumors say R420 is 8x2 variant also ..... and should be cloaked pretty high also with DDR2 ram.
But offcourse this is Hardware Rumor Mill :rolleyes:

[sxotty]

Um why is this NV45 info, I fail to see any info on it, that is false advertising :)

That sounded like a euphemism to me (see bold) :p

It isn't.

Hmm, i'm sure i saw MuFu posting something about NV40 and pipelines, but now it's gone. Or maybe i'm just going crazy. :confused:

Anyway, if what he wrote is correct, well..i'm even more confused about NV40 now. :D

[The Baron]

apparently, it's not 8x2/16x0... or not really. it's really crazy. that's all I know. core/RAM speeds are still what all the rumors have said, but I don't know if anyone outside of NV knows how the crazy pipeline stuff is going to affect performance.

as someone who is far smarter than I once said, "Do pipelines have any significance anymore in CPU-like architectures?" apparently, it's come true sooner than he thought.

As a matter of fact, there is some information though it's not much this time. The guys at 3DCenter only state that NV45 will be the next refresh of the NV40. They also suppose that NV45 will make its debut fairly soon after the introduction of the NV40 chip. Apparently, they think it's all about higher clock speeds.

The article includes some information regarding NV45 but given the fact that even the posted NV40 specs may not be accurate what should they say about NV45? ;)

Yeah, what he wrote must pretty much be what we concluded in MSN discussions, so I'd say it hopefully makes more sense than the old 8x2 crap IMO.

I see nobody figured out what I meant in my last past. What I meant is, even if they hadn't said anything about the NV45, having talk of the NV40 means they're talking of the NV45 - the current NV40 design now closely ressembles the original NV45 one AFAIK. At the same time, this means the NV45 will be a very small refresh, with barely any new stuff, just a speed boost (although possibly a more important one than NV35->NV38 :))

[retsam]

so i take it nv45 is going to be a refinement of nv40 with higher clocks and a few minor ajustments .... so it sounds like nvidia is fucusing alot of resources on nv50 for the release of directxnext i can see them wanting a full compliant part for the launch of longhorn ...this would probably beat ati to the punch but then again who knows ati could be thinking of doing the same thing

Are you implying that the new NV40 is more of a TBDR that the original NV40 in a sense? Or is the talk about the changes in the 'pipeline' more akin to the nv40 being able to work on quads in different stages of its pipeline (I hate using stage of a pipeline of a pipeline as a term). If so, is it possible that (assuming the architecture is still 4x2 like the nv30) the pipeline is split into multiple stages so that it can work on different stages of 2-4 (arbitrary numbers) quads at a time?

Maybe this is all just crap, but it is all I could think of as to why you and MuFu seem so confused about this new part...Is nvidia experimenting with a cpu like architecture for this chip to get ready for NV50?

Well they started with NV3x. NV4x is obviously an intermediary step.

I thought NV50 still used IMR?

[MuFu]

Not sure we're on the same page, mate. I meant it's a further step towards their ILDP/"pool of functionality" ideal, which will probably be first realised to any significant extent in NV50.

MuFu.

[The Baron]

Sorry, thought you were talking about a step to TBDR and got very confused.

Someone has TBDR on the brain, maybe an idea for a new forum avatar ;)

[The Baron]

No no no, I can't have a new avatar yet. I have to find my bloody Photoshop disc...
