mas o R680 é um shrink apenas ou é já o R600 modificado com mais unidades output de texturas e tal ?
já que o R670 é um dual gpu..
será que o R650 é que é o shrink e o r680 é a "new deal" ?

segundo os rumores "da Vrzone" , R680 trata-se de uma solução DUAL GPU (duas RV670 "juntas" ) de seu nome HD2950X2X
ou seja R670 = R800:

ou seja R670 = R800:

INQ reveals the R680, Radeon HD 3870 X2
IN FEBRUARY 2004, a game appeared from nowhere. The name of that game was Far Cry, and it transformed a small team from Germany into international gaming megastars.
It spurred a graphics card bonanza, one repeated by by Doom 3 and Half-Life 2, with the market massively going for Athlon 64+Nforce3/4 systems with Geforce 6800GT, 6800 Ultra for high-end and Geforce 6600 for mainstream.
Now the circle has turned again, with the release of Hellgate: London, Gears of War, Unreal Tournament 3 and Crysis. The time to get a new computer is now, and if you're asking yourself what would be the best $500 present under the Christmas tree, answer is two 8800GT or two 3870s, not an 8800GTX or 8800Ultra.
But, if you're willing to wait, this is what AMD has in store for January release.
Please allow me to introduce myself, my name is HD 3870 X2...
RV670 times two, 512MB GDDR4 memory times two, DVI-HDMI adapter - times two, DisplayPort... erm...
As you can see, this longer board is on the trail of the 8800GTX/Ultra PCB. Unusually, there is no significant increase in the height of the board, meaning this dual-GPU card will fit it a more compact chassis.
The price of 3870 X2 will be between 399 and 499 USD/EUR, 249 and 299 quids (yes, life sucks in Bligthy).
RV670 chips are working at 750+ MHz each. 775 MHz should be reachable by launch time. Who knows, maybe even 800 MHz for the GPU. When it comes to overclocking, we have no idea at the moment, but the memory should be able to work at 2.25 GHz, yielding in combined bandwidth of 144 GB/s. Not too shabby.
Also, with R680, AMD is hoping to finally close the circle the compnay opened with Rage Fury MAXX. This card was hailed by none other than Dave Orton as the first multi-GPU product. But as we all know, there was a small company called 3dfx that did that some years before ATI kicked in. The only problem that Rage Fury MAXX had, was the fact that if you chose to use Windows 2000, Windows XP, or just about any operating system other than Win98/Me, you'd be sitting dead in the water.
With two RV670s inside, owners of this card will have a future since this board will come to market as 3870 X2 and FireStream 9170 X2, albeit with double or quadruple amount of memory (probably GDDR3, not GDDR4). R700 is also bringing MCM concept in the world of GPUs, so we're heading to one very, very interesting year.
Bear in mind that the G92_300 series, or D8E, the GeForce 8850GX2 or 8950GX2, whatever Nvidia marketeers figure it out to be - is also a dual-chip board. It is widely expected that Nvidia's card will be the same as 7900GX2 and 7950GX2, or a dual-PCB connected with 20-or-so connecting pins, all working in harmony with Nvidia's BR04 chip.
Radeon HD 3850, 3870, Nvidia GeForce 8800GT (and soon new G92-based GTS), and now Radeon HD 3870 X2 and Nvidia GeForce 8xx0GX2. Life doesn't get boring in the 3D industry. µ

AMD Considers New High-End Graphics Product Announcement at CES – Sources.
Sources familiar with the plans of ATI, graphics product group of Advanced Micro Devices, said this week that the company does have plans to conquer the market of high-end graphics cards again with the product code-named R680. Unfortunately, the new graphics board will not be released shortly from now and will also have a number of drawbacks.
The rumoured code-named ATI R680 graphics product does exist in the roadmap, sources confirmed. However, the R680 is not a high-performance single-chip graphics solution, but a dual-chip graphics board akin to Nvidia’s GeForce 7950 GX2 or ATI’s Rage Fury Maxx. One ATI R680 graphics card will carry two ATI RV670 graphics processing units (GPUs) with dedicated memory and connected using ATI CrossFire interface for multi-GPU solutions. Actual specifications are currently under consideration by both AMD and its partners among graphics cards makers.
Even though two of ATI R680 boards may provide the power of four ATI RV670 graphics processing engines to enthusiasts without budget constraints, one of such graphics cards may not become the best solution for those demanding high performance, but not willing to pay enormous sums. Performance of all multi-GPU solutions depends on drivers and in case the driver does not recognize an application, performance of a dual-, tripe- or quad-GPU graphics solution may be similar to a single-chip graphics card. Theoretically, ATI Catalyst driver developers may force so-called alternate frame rendering (AFR) multi-GPU rendering technology for all unknown applications for CrossFire configurations, but this may add lag effects in numerous games.
The code-named ATI R680 graphics card is currently set for introduction at Consumer Electronics Show in January, 2008. Since availability timeframe of the final product is currently unknown, AMD may reconsider announcement dates too. Actual product name is unclear as well.
Based on what is known about the code-named RV670 product, the new GPU features DirectX 10.1 capabilities, PCI Express 2.0, DisplayPort and double-precision floating point calculations. ATI RV670 is projected to deliver “R600 performance, better thermal & power”, according to AMD’s own documents. If the information is correct, two of such chips will deliver similar performance to ATI Radeon HD 2900 XT graphics cards in CrossFire mode. Even though in a number of cases two of such chips outperform Nvidia’s GeForce 8800 Ultra, which retails for $849, in many cases the high-performance single-chip product leaves the CrossFire tandem considerably behind, based on a review by X-bit labs.
Officials for graphics product group of AMD did not comment on the news-story.

Lá porque conseguem forçar o AFR em todas as aplicações desconhecidas, espero que o pessoal dos Catalyst não se desleixem e continuem a fazer optimizações Crossfire para cada jogo.
Mas conseguir forçar o AFR em todas as aplicações não conhecidas é muito bom. Relembro que mesmo o pessoal com 7950GX2 quando sai um jogo mais recente e que não esteja contemplado nos drivers, lixa-se e usa só uma das placas (equivalente a uma 7900GT) até sair um novo driver.

Isso ou pode simplesmente criar um novo perfil no driver existente...
Quem tem de esperar por drivers novos para novas aplicações são os users de placas ATI, porque não têm essa possibilidade.

Isso não funciona sempre.
Bem sei porque é que me livrei das 6800GT em SLI. Essa foi uma das razões.

AMD Has R680 Running Stable in CrossFire
....today, we will do one better than that and bring you the first picture of the Radeon HD 3870 X2 running in CrossFire mode!
A picture is worth a thousand words and this one is surely worth that many. I'll spare the details on the card, but since the Radeon HD 3870 X2 has two Radeon HD 3870's on board it's not too tough to figure out. The cards are the longest cards that I have seen ATI make and since the cards have just one CrossFire bridge connector it seems that running four of these in CrossFireX isn't going to happen, well at least for now. It should also be noted that the cards were actually running on a demo system that AMD made available. I was able to play Unreal Tournament 3 with the cards paired in CrossFire and stability and performance were impressive.
One of the coolest features of the Radeon HD 3870 X2 is that you don't have to get a higher priced AMD 790FX chipset powered motherboard with 42 PCI Express lanes to run a pair of Radeon HD 3870 X2's. This means that this can run on lower priced chipsets like the 790X that offer just two x16 PCI Express slots.
The Radeon HD 3870 X2 is set to be released in Q1 2008 if all goes well, and after seeing it in action, I have no doubt that it will come out. AMD is making a comeback in the desktop graphics card market, so sit back and relax as the marketing wars are just now being drawn up.
