HYDRA za manje od mesec dana

Hydra 200 [65nm, trosi 6w struje] je "graficki" cip koji se nalazi integrisan u plocu, koji presrece DIRECTX instrukcije koje se salju grafickimkartama [time se eleminise potreba za bilo kakvim custom driverima, proces radi na SVIM grafickim karticama], i deli te instrukcije na koliko god kartica postoji u sistemu. Znaci jednom recju, load optimizer DX koda.

Vazno je reci da svaka grafcika RENDERUJE ISTI FREJM ISTOVREMENO!!! Svaka po jedan deo. Rezultat svega ovoga je sto vishe NEMA GUBITAKA u preformansama. Totalno linearni napredak u jacini. Primer: imas graficku koja daje 50fpsa u jednoj igri, a na drugom kompu imas jednu koja daje 40fps-a. Ako is stavis u sli mod na ploci koja ima Hydru, imaces 90fps-a sa istim podesavanjaima u istoj rezoluciji. Cak tvrde da mogu i da poboljsaju preformanse malo.

Hydra u prodaju ulazi za 30tak dana. Postojace 3 verzije [Nvidija, ATI i jedan koji ce primati mesane kartice]. Po prvim naznakama cena ploce ce icigore oko 30-50$ [zbog dodatnih high speed PCI-E magistrala i cene samog chipa]

Remez told us Lucid uses a mix of load-balancing algorithms, and he wouldn't reveal too many specifics about how the various algorithms might work. He claims the end result is near-linear performance scaling. Even with mismatched GPUs, if the slower of the two is only 30% the speed of the faster one, the total system could produce nearly 1.3X the performance of a single card alone.

It's difficult to express verbally, but Lucid's demo on the show floor offered a good sense of what's happening. The demo system had two GeForce GTX 260 cards connected to a Hydra 100 and enclosed in a box. A PCI Express cable then attached this test mule to the PCIe x16 slot in an enthusiast-class system (based on an Intel chipset). The whole setup was running Unreal Tournament 3. On one screen, we could see the output from a single GPU, while the other showed the output from either the second GPU or, via a hotkey switch, the final and composited frame. GPU 0 was rendering the entire screen space, but only portions of the screen showed fully textured and shaded surfaces—a patch of the floor, a wall, a column, a sky box—while other bits of the screen were black. GPU 1, meanwhile, rendered the inverse of the image produced by GPU 0. Wiggle the mouse around, and the mix of surfaces handled by each GPU changed frame by frame, creating an odd flickering sensation that left us briefly transfixed. The composited images, however, appeared to be a pixel-perfect rendition of UT3. Looking at the final output, you'd never suspect what's going on beneath the covers.

Assuming the Hydra 100 does work as advertised, the big questions now are "How does it really perform?" and "Who will make use of it?" As for the first question, we got a demo of Crysis running at 1920x1200 at the highest quality levels available in DirectX 9. The test system was using a pair of GeForce 9800 GTX cards, and performance ranged between 40 and 60 FPS on the game's built-in frame rate counter. The game played very, very smoothly, and I didn't perceive any latency between mouse inputs and on-screen responses.

jej nema vishe prodaje grafike zarad kupovine nove, samo dodash josh jednu

Pa da, ako si u startu doplatio 50evra više za ploču onda samo ubaciš drugu

Inače ovo ovako na papiru zvuči interesantno, priznajem da nisam pročitao ništa u vezi ovoga pa zato imam onako pesimističnu viziju u vezi ovakvog rešenja. Nekako ne mogu da zamislim da ATI i nvidia grafička radi bez problema u istoj ploči i još skalira savršeno. Mislim super će biti ako bude tako ali...ajd videćemo kada to stvarno zaživi i isproba dosta ljudi

Kako bi voleo da ovako nešto zaživi... Ovo mi deluje kao najlepši san:

Upravo ovo iznad je nachin razmishljanja svih neupucjenih u crossfire i sli. Da se ogradim, vecina ljudi sa kojima sam pricao na tu temu kada su culi da kada stavish 2 graficke karte [ koji si ludak zashto bi to radio lol] misle bash tako, da cje imati duplo bolje performanse.

Mislim da je krajnje vreme da se nesto tako i uradi. Gotovo mi je nemogucje izledalo da se i "od pocetka" takva stvar nije probila. A da..pa nije zbog kesha : )

All eyes on hydra !

Savrshena zamena za Northbridge.

Nadajmo se da nVidia ili ATi nece da otkupe firmu, i da ce da ostane nezavisna!

Teško, iza Hydra-e stoji Intel preko Intel Capital's i prikazana je na IDF-u.

"Intel’s newest high performance Core i7 and Core i5 processors coupled with the Intel P55 Chipset provide an ideal platform for Lucid to introduce its new GPU sharing technology,” said Zane Ball, Director of Microprocessor Product Marketing. “Intel Capital’s longtime investment into Lucid has contributed to the delivery of this important technology, which will afford enthusiasts new choice and flexibility to unleash performance.”

Verovatno ce buduća verzija a možda već i ova podržati i Intel GPU-ove(Larabee ili ove buduće GPU in CPU integralce iz core i3,i5 serije) koji će da se uparuju sa drugim GPU-ovima.
