GeForce GTX 480 has 480 CUDA Cores?

In several of its communications about Fermi as a GPGPU product (Next-Gen Tesla series) and GF100 GPU, NVIDIA mentioned the GF100 GPU to have 512 physical CUDA cores (shader units) on die. In the run up to the launch of GeForce 400 series however, it appears as if GeForce GTX 480, the higher-end part in the series will have only 480 of its 512 physical CUDA cores enabled, sources at Add-in Card manufacturers confirmed to Bright Side of News. This means that 15 out of 16 SMs will be enabled. It has a 384-bit GDDR5 memory interface holding 1536 MB of memory.

This could be seen as a move to keep the chip's TDP down and help with yields. It's unclear if this is a late change, because if it is, benchmark scores of the product could be different when it's finally reviewed upon launch. The publication believes that while the GeForce GTX 480 targets a price point around $449-499, while the GeForce GTX 470 is expected to be priced $299-$349. The GeForce GTX 470 has 448 CUDA cores and a 320-bit GDDR5 memory interface holding 1280 MB of memory. In another report by Donanim Haber, the TDP of the GeForce GTX 480 is expected to be 298W, with GeForce GTX 470 at 225W. NVIDIA will unveil the two on the 26th of March.

I can't wait to see this farce coming to an end.

Wile EEven the GTX280 had 11% more shaders than the 260 core 216 (even bigger difference for the original 196 shader 260's). If this rumor is true, the 480 only has 7% more than 470.
I was thinking that the GTX275 and GTX285 were more similar to the GTX470 and GTX480, in which case there is a bigger gap this go 'round. I don't know how fair comparing a 260 to a 280 is (aside from that they are both launch cards), but I see where you are going.

450/300 sounds a lot closer to what I was hoping they would release the cards for than what everyone else was saying. This shows nVidia isn't completely bonkers. For 300 I will stay with the green team.

this will be a solid card... it would have been a solid card 8 months ago, when it should have been released, but these things can happen when one tries to cram 20lbs of ***t in a 10lb bag.

with this price will be good deal, better than ATI, and about 512 cores i think they plan for GTX490

yeah but the GTX470 will have about 20% less raster performance than the GTX480

still I wouldn't buy a GTX480 for 500 but im just sayin(tryin to think of somethin nice to say about em)

but it sounds like that the bulk will be done with artificially low core/memory clocks... as soon as that bad boy is OC'd it will be right up there with the 480.

IF they are OC-able, but i doubt because, the core already hot as hell

DanTheBanjomanOf course not, but it is not like AMD, Intel or whatever company have decent naming schemes. For some reason naming has to be as cryptic as possible.
Yes to confuse the crap our of people so people don't know what the hell they are buying.

Yes. But Ati can lower their current card's prices anytime, making a huge gap in a performance / dollar.

.....Yeah, but AMD/ATI has 1600 shader cores!!! More than 3 times!
xtremesvI keep saying... rumooooorrrrrs. Show me the numbers.
Numbers are irrelevant! Benching is futile!

Half of year is almost an eternity on a very tight competition market.

Bjorn_Of_Iceland1 ati shader core != 1 cuda core
indeed, the are pretty much uncomparable. But for laymans 'rough' conversions, it has generally been 5 ATi cores = 1 nvidia core for a while for equal performance cards. Nothing to do with efficiency or one company being better ect. It's just architectural differences between them. This time looks like it'll stay that way, roughly (maybe 4 = 1 this time).

Also, if those prices are correct AMD will still win out. People have forgotten how long the hd5xxx series has been out for. OF COURSE AMD are going to go on a price slashing spree :) if nvidia can match the hd5xxx series prices for 6 months ago then big whoop, they should've done so 6 months ago! Which is going to be awesome for everyone, i personally can't wait to see sub-£200 hd5850's.

On a side note, catalyst 10.3a has added pretty decent performance boosts in a lot of games, they're the drivers ATi has obviously been saving for the eventual release of fermi (judging by how there has always been talk from AMD of awesome drivers whenever they were close to a fermi release date, now it's final, they've been released).

It doesn't matter even if it was 100 ATi shaders = 1 cuda core, both hardware designs work differently and may provide similar results.

Good point. The cat 10.3 are wonderful but I can't wait for cat 10.4 to come out :eek:

GeForce GTX 480 : 512 SP, 384-bit, 295W TDP, US$499

GeForce GTX 470 : 448 SP, 320-bit, 225W TDP, US$349
If this is true I don't see a Dual Fermi coming out anytime soon unless they make it with GTX 470 and lower clock speeds. Dang, that 480 is cooking up a storm. I can see the HD 5970 with that much heat output for a Dual-gpu but a single? Good luck on keeping that 480 sucker cool. I don't see much overclock headroom right now.:eek:

The guy at VR-ZONE changed his mind, put these numbers up:

GeForce GTX 480 : 480 SP, 700/1401/1848MHz core/shader/mem, 384-bit, 1536MB, 295W TDP, US$499

GeForce GTX 470 : 448 SP, 607/1215/1674MHz core/shader/mem, 320-bit, 1280MB, 225W TDP, US$349

:laugh: Now that makes more sense. I knew NVIDIA had issues running when 512 SP. (16 x 32 = 512) they run in blocks of 32, so they would have to disable one block. But I read the problems were scattered all over the place, I guess they didabled the worst section.

I was kind of skeptical about the jump from 448 to 512 myself.

Power consumption of these things is still insane. Now we will get to put our way overpowered PSUs to work!

Fudzilla is to ATI as Charlie Demerijan is to NV. Well maybe not quite like that but it's generally very NVoptimistic.

Besides the article has next to zero content (unlike most of the very recent GF100 info) and it's a picture of a box with no other writing apart from 'Zotac' and 'GTX480'. Oh it has a crown on it. That must mean it's made of gold or something.

Avoid (Fud)zilla. Stick to TPU, BSN and Anandtech IMO.

Fudzilla gets info quite fast mostly before anybody else. It based on speculation same with Semiacurate and The Inquirer. Nothing wrong with that because most of hte time they are right on the money an before anybody else.

oops, my bad.

But... just clicked it there. What am i seeing? The same GTX 480 - no clock details so why speculate about it's overclockiness?

and this...

launch a special limited edition packaging and a limited number will be incorporated into a number of media is currently being carried out in order first to be sold.

....means jack all. Except perhaps to imply there will be added incentive given away with card (such as the razer mice).

Now, if indeed it is fact that razer mice are being given away with the cards, this indicates Nvidia's massive investment in marketing this card. If it were stand alone superb, it wouldnt require quite so much *ahem* pomp and ceremony and whoring it out with other peripherals.

Or is it, Buy a Razer Deathadder and get a free GTX 470?
