View Full Version : Ati's R520 to arrive in May
"ATI PLANS to introduce its brand new R520 technology exactly a year after it announced its R420."
"Our biggest concern about R520 is its manufacturing process. ATI will build it using a 90 nanometre process and this might be tricky. Shifting to a smaller process is always problematical, not automatical."
Inquirer (http://www.the-inquirer.com/?article=20896)
Interesting...Let's see if the R520 becomes this monster, Inquirer is talking about.

Sounds good,
I cant wait for more details to 'leak' out I wonder if it really has 24 pipes :d
i bet thats about the same time nvidia will release there next gpu 24 pipe card ... to counter the r520 mmmmmmm 24 pipe sli....mmmmm

Yepp another year of Graphics goodness
So much for the "no new gpu till the end of 2005" rumor :D
retsam i bet thats about the same time nvidia will release there next gpu 24 pipe card ... to counter the r520 mmmmmmm 24 pipe sli....mmmmm
Dual NV47s ?? .. possible
It was "No new technology in 2005". If either the NV47 or the NV48 exist, then they will be released this year. NVIDIA has nothing against ATIs R520.

Well the R520 is supposed to be new technology at least for the ATi side , because its going to be the first ATi gpu to support SM3.0 .. (or Smart Sahder 3.0 as ATi like to name it in thier lines of video cards) . & perhaps a 512MB framebuffer .

What makes you so sure an nv47 or 48 can't go up against a r520? the gf 6 line already is capable of higher performance in pixel shader operations, abit they are a bit slower in the vertex shader departement but that could be changed for the nv 47 or 48.
the r520 is a modified r300, 420,480 with sm 3.0, maybe it won't be able to keep up with the nv47, I don't see ATi making big changes to the ALU's to allow more effeciancy in the pixel shader's, since making changes to the ALU's will mean completely redesigning the core. Given that they are using .9 fab process most likely with low-k (this is probably why they skipped .11 for thier high end cards) because they need to get thier clocks up higher just like the r420 and r480 to keep up with the lower clocked nV40's and a bit faster depending on what is being run.

Because clearly you know how the R520 is going to perform, right? This happens every generation, everyone says one's going to be better than the other, and in the end, they perform virtually the same.

Didn't Nvidia annouce that they didn't exist?

No the INQ did. Then it said they were wrong. Then it said they weren't sure. That's the INQ, they're never wrong because they cover all possibilties.
With that said the R520's going to take an immediate hit on yeilds [60-80 million more transistors] and because of 32-bit precision. If you're expecting a 9800XT to X850XTPE/5950U to 6800UEE jump don't hold your breath, I doubt we'll see that happen again for a while.
Xbit labs and Digit times said the nv 48 does exsist a 24 pipeline version of the nv40 so it should be around a 50% increase in performance, plus there should be alot of other performance increases, like for texture lookups with in the vertex shader, right now there is an overhead of 20% for this, flow control should be faster, and fp 16 blending which is already faster in the nv41 derivitives. I'm presuming there will be quite a bit of new features on this chip too from what I've been hearing. Possible much faster vertex performance.
I don't think its going to be a 24x1 layout, more like a 12x2, this should help reduce costs, but giving a good deal of performance boost. This also goes for the r520 aswell.

This also goes for the r520 aswell. i think its gonna be 24x1 i dont think its gonna be 12x2 unless they will have dynamic allication of the pipes which david k said they are not gonna do. and remember with the nv47/48 they transister count can be reduced becouse they will remove reduntante transisters. and all the broken ..cough... hardware mpeg....cough will be fixed and also 24x1 will be possible becouse its gonna be .11u
Future games will be less fillrate dependant and more shader dependant. the NV43 anticipates this trend. While being able to draw only 4 pixel at once it can process up 8 shaders. Which is something different from having a 4x2 card setup.
The successor of the NV40 may be a card still able to draw "only" 12/16 pixels but with more shader processing units (24 as rumored ?)

Ehter side pulling out a 6 quad card wont be as shocking as the trasnition from 2 quads to 4! So honestly ill be a bit suprized, but not shocked!
What I meant was that if NVIDIA doesn't release either NV47 or NV48 then they don't have something against the R520. And what I think is: ATI is as good as NVIDIA but NVIDIA has a complete new generation (NV40) whereas the R420 & R480 are just higher clocked R350. They are even now.
The R520 will be something new and it's just a guess but I think, it will kick ass!

I heard the 520 was nothing more than a warmed over X800 with PS 3.0 and
a few other features. Who knows. :angel:

Sorry about that weet misunderstood, well I think its going to be a close one, both the nv 47,48 which ever has the 24 pipelines, will perform very closely to the r520.
does anyone else here think ati are going to be able to repeat that r300 core? That core was and still is awesome

I think it still has some life in it aslong as they can clock around 100 mhz higher then nV's cores and get them out working properly.

Theres like 2 or 3 of you in here that are complete Nvidia fanbois and saying stupid things that make no sence. First of all the R520/R500(Xbox) is a completely respun core using totally different voltages, clock speeds, and manufacturering process. They are not using the technology of previous cores as bodly as the R300->R400. If you think different, guess what, you're wrong! What you are saying makes about as much sence as me saying 'Well the NV50 is going to be an NV20 but just faster with new stuff!'. Its like, what the hell did he just say?
Second, the SM3.0 from ATI will support full 32bit buffer, which completely surpasses the curren NV40+ line out under their sm3.0 which is limited. (the main cause why SM3.0 supported games dont run faster and in some cases worse then ones that support 2.0 or 2.0b) The card is going to have 24 pixel pipes, and 8 vertex pipes. Simple as that. These are basically facts now as the core is already out for testing. Whats Nvidia have? Nothing. Absolutly no word has been said beyond pure speculation. Believe me, i have my SLI board right here waiting for 2 next gen cards, im as hungry to see what both have to offer as the next guy or gal, but right now Nvidia simply has no cards or even hinted info showing.
One other thing, slightly off topic, is that people think 512mb cards are going to be like double the speed of current GDDR3, for example on the PE and U. This is false. The 512 GDDR memory for the cards will be in 128bit for this years release. Much like the 9800PRO of old being in 256mb 128bit until the XT was released. So while its more ram, it will handle less 'info per cycle' to dumb it down. You can expect the GDDR3 (or 4) 256mb 256bit versions to put up a nice fight in terms of 3d benchmarks. Though i still think the 512s will prove better in the long run simply because its double the space to store information and less of a strain on the card. It wont be some massive boost or be anywhere near 100% better. Lets hope Nvidia releases something soon, because personally, im putting my money down on the first thing to show its face, and as it stands, i dont even know what Nvidia will be throwing. The worst thing they can do is upgrade the Nv40 core with its current problems with needing bios upgrades, drivers, and stuttering in games. NV47/48 will never see the light of day. NV50 was scrapped for a reason, they restarted from scratch. Keep in mind EVERY mid year graphics card release from Nvidia and ATI has been basically, a new tech core, not to mention everyone from Nvidia has ended with a 0.
oh boy were do i start with this dude .....

You don't. I was thinking of tearing him a new orafice but decided not to. It would be like break-dancing in front of a cripple. It's just plain mean.
First of all the R520/R500(Xbox) is a completely respun core using totally different voltages, clock speeds, and manufacturering process. isnt that called a die shrink ???

if you followed gpu's as close as you say you do you would know that some components in the nv4x are the same as the nv2x..... i cant find the link right now about reuse of internal components but when i do ill post it here

Whats Nvidia have? Nothing. thats called keeps your corperate secrets close to your vest and waiting for the other guy to show his hand... its also called ...SMART

why would you buy an sli board now when you are waiting for these so called cards that arent even announced and probably will not be out in retail for what 6 to 8 months ....
One other thing, slightly off topic, is that people think 512mb cards are going to be like double the speed of current GDDR3, for example on the PE and U. This is false
this is a gpu site devoted to every thing gpu related those that have been here long enuff know better. we all know unless you have massive amounts of textures memory makes little diffrence. also you make it seem like were all a bunch of dopes and only you are smart enuff to know better....
NV47/48 will never see the light of day. NV50 was scrapped for a reason, they restarted from scratch and you know this from how ?? oh wait this is more rumor monegering .....
Keep in mind EVERY mid year graphics card release from Nvidia and ATI has been basically, a new tech core, not to mention everyone from Nvidia has ended with a 0
what was the nv25 then....
You don't. I was thinking of tearing him a new orafice but decided not to. It would be like break-dancing in front of a cripple. It's just plain mean. hahah i guess im mean then oh well
