AMD Catalyst 8.6 supports RV770-Chips [SIZE="1"](ještě aby ne :D)[/SIZE]
[QUOTE="Hardware Infos"]As we hear exclusivly from sources close to AMD, the Catalyst 8.6 provides already support for RV770 cards. Apparently it seems to Launch 4 different versions.
What exactly these are, we can not say. Possible are different RAM configurations - GDDR3/GDDR5 - and the GPUs RV770Pro and RV770XT.
In a few days we are all hopefully wiser.[/QUOTE]
Ty verze budou kromě HD 4870 GDDR5 a HD 4850 GDDR3 možná něco jako HD 4870 GDDR3/4 (nebo obojí ?) a HD 4850 GDDR4(5 ?)...no, počkejme si :)

a neco k budoucimu "low endu". Mam uz dojem, ze tento lowend bude vykonostne jak moje karta-kdysi vyssi mainstream-nizsi highend :)..
obecne to vypada, ze hd4850/4870 budou gf karty, ktere nebudou mit nejaky cas konkurenci ve sve tride. Snad nebudeme tedy zklamani a ocekavani dle slidu a specifikaci a stripku se ukaze jako pravdive.

A neprijde ti divny ze obe varianty rv730 maj uplne stejnej takt pameti a deli je jen ubohych 20% taktu na jadre?
Jedine cemu bych byl ochoten jeste verit, je to ze, 46x0 budou vyuzivat rv670 alias rv730, v tom pripade ale neverim ze obrazek chladice na predchozi strance doopravdy nalezi rv730. Vyuziti rv670 v dalsi generaci by davalo smysl, pac rv635 je silene malej chip, rv770 je zas oproti rv670 o dost vetsi a vznikla by tim dost velka mezera mezi rv770 a rv635. Vylepsovat nejak vyrazne rv635 nema moc smysl, kdyz je tady rv670.

No ta delka je teda dost. Snad se mi to vleze do Gigabyte GA-MA78GM-S2H. To je myslim miniATX deska. Snad nebude nic prekazet
Teda ta délka mě taky překvapila..Jinak se obecně divím,že paměti DDR4 nebyly nikdy nějak masivně používány jako např. DDR3

[QUOTE]While we are away for Computex, CJ let us know that the Radeon HD 4870 X2 R700 prototype card is out and it beats the NVIDIA GeForce GTX 280 in 3DMark Vantage. The R700 card is basically made up of two RV770 GPUs with 2x256-bit memory interface to either GDDR3 or GDDR5 memories. We asked our sources about R700 in Computex and apparently AMD is going to let AIB partners to decide the specs themselves. Therefore, the partners will set their own clock speeds, PCB design, memory types, cooler solutions etc. and there will be Radeon HD 4850 X2 and 4870 X2 cards differentiate by the memory type. The R700 card apparently doing pretty well at this stage scoring about X5500 in 3DMark Vantage Extreme preset while the GeForce GTX 280 card is scoring X4800. Both sides are still working hard on optimizing their drivers for the new architecture so probably we will see the performance to improve over time.[/QUOTE]

[QUOTE]It seems that NVIDIA believed that RV770 would only have 480 shader processors, and only be a modest upgrade of the RV670 core. This is suppose to be one of the reasons for the rather high prices of the GeForce GTX cards, that and the ridiculous manufacturing costs. Now that it has been unveiled that RV770 does not have 480 shader processors, but rather 800, it seems NVIDIA might lower the price of the GeForce GTX 260 to make it a bit more appealing in comparison to Radeon HD 4870. We're hearing $399 from more than one source, but we're also hearing that Radeon HD 4870 might not come as cheap as hoped, $349. The GeForce GTX prices are expected to stay put for a long time, but AMD has every possibility to lower the prices of its new graphics cards, if sales are slow, without losing much money.[/QUOTE]

"Game physics processing capability" - je to Havok :)
[QUOTE]Sunnyvale (CA) – AMD had to find an answer to Nvidia’s Ageia acquisition and the conversion of the PhysX engine into CUDA. We knew that AMD’s graphics team was up to something, since the manufacturer was highlighting “game physics processing capability” in its RV770 launch materials. Now we know, since AMD just announced a partnership with Havok. In case you are wondering: Yes, that is the same company that Intel acquired last year and now is a subsidiary of the blue team.
One month ago, we were fortunate enough to come across numerous launch details of the upcoming Radeon 4850 and 4870 graphics cards and the specific note of physics processing capability got us scratching our heads. Since Ageia was snapped up by Nvidia and the PhysX API is pretty much converted into CUDA on the one side and Intel secured Havok’s physics engine last September, we were wondering what AMD (ATI) was up to. They must have been developing their own physics engine along the way, right?
Wrong. In an announcement that we have to admit caught us a bit on the wrong foot, we learned today that this physics processing capability will come from Havok. AMD’s Godfrey Cheng, director of product marketing in the company’s platform and gaming technologies division, stressed today’s news does not include a product announcement, but simply points out that there is relationship being formed between AMD and Havok and the two companies are working together to “optimize” physics processing on AMD CPUs and AMD (ATI) GPUs.
So, why Havok? Cheng reasoned that Havok’s technology and toolset have been widely accepted by developers and are considered to be “very mature”. He also noted that Havok follows AMD’s open approach philosophy. The executive indicated that Nvidia’s PhysX strategy does not match AMD’s strategy and that the company does not believe in forcing people to use a particular API. While Cheng said that AMD is aligned with Havok at this time, he did not want “exclude” a possible future announcement regarding PhysX. No such announcement is currently planned, we were told.
AMD said that Havok’s physics technology “scales extremely well across the entire family of AMD processors, including quad-core products such as the AMD Phenom X4.” As part of the collaboration, Havok and AMD plan to “further optimize the full range of Havok technologies on AMD x86 superscalar processors.” The two companies said that they are also “investigating” the use of “AMD’s massively parallel ATI Radeon GPUs to manage appropriate aspects of physical world simulation in the future.”
While we are still a bit dazzled by the fact that AMD decided to go with an Intel-owned physics engine (and we are pretty sure that some people at Intel may be a bit surprised as well), Cheng stressed that Havok remains “independent” from Intel. Also, while we do not have any confirmation for this speculation, this relationship appears to be driven by the ATI team, which anyway has been working with Intel not just pre-AMD, but also recently on graphics products for Montevina (Centrino 2) notebooks as well as Crossfire X solutions. So this relationship may not be as awkward as it first sounds after all.
Now, of course, we are interested in seeing in what products this relationship will result.[/QUOTE]

Takže, OBR na pct potestil dvě HD4850, ovladače 8.5 (jedna prý odmítala bety, které jsou dostupné na netu) a údajně je velmi mile překvapen (což u něj v kombinaci s ATi poslední dobou nehrozilo). Výsledky jsou asi takové, že v Crysis je CF nad úrovní GX2 v 1920*1200. Škálování výkonu v 3DMarku je prý doslova šokující... výsledky budou již brzy :)

mam nejake informacie o konkretnom modely Asus EAH4850 512 MB:
Gafická karta s chipom ATI Radeon EAH4850, pamäť 512MB 1,9 GHZ DDR3. 256-bitová, rozhranie PCI Express x16, Dual DVI link, podpora HDMI, podpora HDCP, Výstup HDTV-out, DX10, CrossFire Multi-GPU ready, rozlíšenie do 2560x1600. Podpora DirectX 10.1, OpenGL 2.0, Shader model 4.1, full bitstream VC1.
V podstate vsetko zname, skoda, ze tam nedali aj takt GPU. A cena tejto karty je okolo 4300 CZK s DPH (+-100).

No,myslim,že tatto nová řada je úžasná,už si brousím zuby na EAH4850.Jinak se chci zeptat,všude psají něco jiného,kdy má být k dispozici 4870x2,tak nevíte kdy mají přijít?Jde mi jen o info.
Tak bud maj nejakej bug v biosu a nemaj nadefinovany powerplay staty, nebo je proste ta 2d spotreba obrovske zklamani... :(
vykon ovsem supr, situace se zase obratila a Nvidia myslim na tyto karty nenajde adekvatni odpoved (leda zlevnovanim, ovsem to situaci prilis nevyresi, jsme rad, pekne at jde Nvidia tam, kam patrila za dob x19xx serie :D )
Takže, je potvrzeno, že NDA na HD4850 končí dneska v 15.00, údajně jsou povoleny jen preview, konkrétní informace týkající se architektury budou k dispozici až později.
A máme tu review z TweakTownu, výsledky jak single karty i CF: http://www.tweaktown.com/articles/1470/radeon_hd_4850_in_crossfire_at_4ghz/index.html

Kde ? Za půl hoďky je na webu aktualita, píšu tam, že dle Fudzilly jako první je měl k předobjednání CZC, ale pak je stáhli. A před hodinou tam pořád nebyly. :notsure
Já jsem se koukal k dodavatelům. Jeden dodavatel měl (bude mít) 5ks a ty už jsou pryč...nevím pro koho...
Ha, tak pod výrobcem na CZC jsou. IMHO to budou brát oni, mají novinky často jako první. Vzhledem k ceně možná připlácí za ekxluzivitu (že přeplatí ostatní) nebo to třeba dostávájí jako první díky odběrům a tak...no, uvidíme jestli budou dneska skladem.
Hm, už jsou položky i v Alfě...
