GeForce GTX 580

If they release it I doubt it would be a real production card. It just doesn't seem feasible to significantly increase the complexity of the GTX 480 without a die shrink.

If it actually comes out, it will probably end up being something along the lines of the 6800 Ultra Extreme or 7800 GTX 512MB; cards that were produced in a limited quantity and virtually impossible for an end user to get for the purpose of winning benchmarks on websites
 
I don't see a 512-bit memory bus.
They would be much better off "fixing" the current 384-bit to allow them to use faster RAM. Why bother to increase costs and die complexity when you can get a "free" 50% increase in memory bandwidth by using faster RAM (they are at what, 3700MHz and we have 6000+MHz GDDR5 already).

Plus it allows them to do 1.5 or 3GB cards and have a RAM advantage over ATI. If they went 512-bit, I think 4GB on consumer graphics cards is too much, and they would have to settle for only equal RAM (2GB).

(Is the GTX480 even memory bandwidth limited?)

Bookmarked!

Already discussed here......

Going to call this out as either fake, or as an extremely limited production run card. Fermi's already too hot and power hungry.
 
I wish it was true but there is just no way, not on 40nm. Even with the rumored specs it might not be enough to even match a 6900 let alone truly challenge it.
 
It's a good PR move by them, paper launch a non-existent product with theory benchmarks or just a bunch of what-if specs to try and keep enough nVidia fans from buying up the 6xxx series and keep waiting.

Look how many waited for the 4xx series of cards and look how long they waited. nVidia knows their user base and how to string them along.

Hit the nail on the head here. Nvidia always seems to come up with something come AMD launch time to rain on their parade, be it 'big bang' drivers or a leak of a possible maybe could be new product. This has also been used at extent on this forum in the past by some members (I'm sure you know who they are) as a means to cast doubt on AMD's new product and suspend a possible sale (AMD) for a future one with Nvidia.

I don't have any particular problem with it, this is marketing and business after all- just good to be aware of these things.

As for a 480 sucessor I'm sure there's something in the pipeline. Both Nvidia and AMD have multiple graphics designs in the pipeline by different teams. The GF100 team may have been delayed by TSMC but perhaps the GF110 team wasn't and the timeline has held up pretty well- just speculation at this point but these things do happen. I'll be waiting until the Cayman launch articles appear before I make any decisions about upgrading 🙂.

Yea , your probrobly right, I can see Nvidia not releasing anything new till late next year. 🙄

You were kidding right?

You have to be kidding if you think Nvidia could make an even larger and more power hungry chip than the 480 on the same tech process and produce it at volume. The GTX 480 uses more power than the 5970 already. They have passed the 300W limit of the PCI Express slot already as well. You expect them to go further? You're rolling your eyes at someone expressing doubt about this?
 
happy medium said:
SO you think there gonna release a 480 sp gtx580 with higher clocks and more memory? So a overclocked gtx480 with 3gb of memory and call it a gtx580?

No I'm saying that unless NV does a complete rework of GF100 (why bother? if I were them I'd focus all of my energy on Kepler and Maxwell), a GTX480 refresh will probably be rare and highly priced, sort of like the infamous ATI "Press Edition" several years ago with the X800XTX-PE. Maybe it will be a specially binned GTX480, one with everything enabled at higher clocks at same voltage or something. If so, it'll be rare indeed.

So you are saying they will have nothing faster then a gtx480 and no new high/midange cards till LATE next year when the move to a new process?

A full year and a half after FERMI.😀
You guys are too too much.

OK this I can handle.

BUT
no gtx 475 ,no gts455, no dual gtx4xx card? Nothing? You guys gotta be kidding.
 
nVidia is too focused on this CUDA/PhysX crap and AMD is taking advantage of it by releasing pure performance/price cards.
 
512bit ram on a single chip doesn't seem likely to happen, but a dual chip card based on binned 460's doesn't seem so far fetched.

I didn't comment about any other cards, only about a potential GTX 580. It wouldn't surprise me if NV has been building a stockpile of specially-binned, fully-enabled GF104s to combat Barts with.
