r580, g72/80

[Snakexor]

will the differences between those two gpus be a bigger leap in performance/technology from current gen (g70/r520) then what g70/r520 was to r420/480-nv40/42/45??

personally i dont think the jump is as big as it shouldve been ie. 9800pro->x800xt/6800ultra

 

[mrkun]

My understanding is that the R580 will be quite a leap ahead, whereas G72 is just a refresh for the current generation. G80 is supposed to compete with R600 I think.

None of us know why bother asking?

Isn't G70 a "refresh" from the G60 architecture as well ?

I mean I haven't noticed words such as "new architecture" and similar descriptions within GeForce 7 series reviews. NVidia had a new architecture with the GeForce 6 series that's for sure. But the 7 series is a refresh, and G72 is a refresh of the refresh. Heh. It's still welcome though !

Same goes with ATi, mind you. And is even worse I'd say.

ATi's last "real" new architecure was the 9700. And then it was always a refresh upon refresh releases, up to the latest X850 series.

But now, the R520 is a new architecture, and according to what I've read, R580 will be more than just a refresh from R520.

r520 is not a new architecture. its a refresh of r300. the next ATIs new architechture i believe is r600

Well, from AT's insider info, it looks like the R580 will will be in a socket (not soldered) on the graphics board and will not be announced until after March 2006. Of course, that is to be expected anyway, since it is only 6 months away. ATI will probably do a refresh in the Spring and have the R580 ready for late summer. That is just speculation, of course. The R580 most likely has not taped out yet. That will probably occur this winter. Pipes/clock speed/etc. will be determined based on yield at that time.

The G72 is just a 90nm shrink of the 7800 GTX. They may bump up the clock speed, etc. but nothing has been said yet. It is due early in 2006.

 

[Zenoth]

"Running on a 90nm TSMC process has given ATI the ability to push clock speeds quite high. With die sizes small and transistor counts high, ATI is able to pack a lot of performance in their new architecture."

R520 IS a new architecure. And not only Anandtech confirmed it, but it's also a technical fact that you'll have to live with, swatX.

 

[tuteja1986]

ATI R600 would be much easy to produce than current R520/R580. I don't think ATI will any problem on having them on stock on launch since the xbox 360 which sort of like the R600 had no die problem. TSMC said they were going good to have about over million produced by end of October.

Do you have a 512bit internal memory ring bus on your Radeon 9700?

Or SM3.0 which IIRC requires 33% more transistors as it has to support FP32 not the FP24 supported by R300 and up (R4xx)

Ask Rollo about the next Nvidia. His "insider friend" should know about it.

do u really know what a internal ring bus blablub is? i do not thats for sure, but i agree in that it sounds very cool.

R580 has indeed taped out and their partners are already working with samples...according to news on the front page of AT.

[KristopherKubicki]

So the AIB and the NVIDIA manufacturers don't really know if G72/G73 will be 90nm. I haven't seen enough documentation in either direction to really comment on that either.

Someone did hit the nail on the head though about the refresh on the G60 series- G72/73 are pin compatible with the existing 6600 series cards. The NVIDIA partners don't even need to change the PCB for the new chip. Someone mentioned they might add a 6pin molex to the board too. I talked to the guys who designed the cooler for the reference board too, and I am probably going to publish on that later too.

i got an editor to post in my thread awesome 🙂....and it looks like ill do an overhaul from this a64 2.6, msi neo2, and 6800gt@ultra when r580 comes out 🙂

Exactly. Or hardware support for high-quality AF with minimal performance hits?

R520 is a new architecture. R4xx was the carryover from R300. Sure R520 carries over a lot from previous generations - everything does!

Nvidia hasn't fundamentally changed architecture since NV30, they just made it not suck in NV40 by using 16 pipelines instead of 4/8/whatever nonsense NV30 had, wich was not a good match for the FP32 support. NV40 to G70 certainly wasn't a large architectural change.

Regardless, the whole issue of whether or not it's a "completely new design" is kind of a debate on semantics. Either it performs well and competitively or not...

R580 shouldnt be released anytime soon, because it would cripple the R520 sales alot.
That is why the G72 or G7x will be competing against the R520.

When the R580 is released, the G80 will be released.

G80 is NV50, which Nvidia has been working for a LONG time. It is the supposed to be the next gen from the NV40. That is why the G70 (NV47) is similiar to the NV40 in terms of architecture.

Funny thing is that NV40 never had that refresh, such as X800XT(R420) --> X850XT(R480).

No one knows about R600 as its way too early to know what sort of a beast it is.

And also the G70 midrange cards will be alot cheaper due to the fact it can use the same pcb designs from 66000GT etc, hence no need of creating a new pcb which results in more money being used.

Just my 2 cents.

Oh, and supposedly the G80 is a unifed shader architecture and is completely different from NV40 and will use GDDR4 memory.
