Munur á CrossFire og CrossFireX?

[gunni123]

Ég var að spá hvort það væri einhver munur er á crossfire og crossfirex ég veit að þegar maður er með crossfire getur maður tengt 2 kort saman og "sameinað" þau svo maður fái meira performance, en ég var að spá hvort crossfirex væri alveg eins eða er það eitthvað öðruvísi?

Sami hlutur, sitthvor kynslóð.

Þeas, fyrsta og önnur kynslóð hétu CrossFire, og voru meira software based. Þriðja og núverandi kynslóð heitir CrossFireX.

With the release of the Radeon X1950 Pro (RV570 GPU), ATI has completely revised CrossFire's connection infrastructure to further eliminate the need for past Y-dongle/Master card and slave card configurations for CrossFire to operate. ATI's CrossFire connector is now a ribbon-like connector attached to the top of each graphics adapter, similar to nVidia's SLI bridges, but different in physical and logical natures.[5] As such, Master Cards no longer exist, and are not required for maximum performance. Two dongles can be used per card; these were put to full use with the release of CrossFireX. Radeon HD 2900 and HD 3000 series cards use the same ribbon connectors, but the HD 3800 series of cards only require one ribbon connector, to facilitate CrossFireX.[6] Unlike older series of Radeon cards, different HD 3800 series cards can be combined in CrossFire, each with separate clock control.
Since the release of the codenamed Spider desktop platform from AMD on November 19, 2007, the CrossFire setup has been updated with support for a maximum of four video cards with the 790FX chipset; the CrossFire branding was then changed to "ATI CrossFireX". The setup, according to internal testing by AMD, will bring at least 3.2x performance increase in several games and applications which required massive graphics capabilities of the computer system, the setup is targeted to the enthusiast market.
A later development to the CrossFire infrastructure include a dual GPU solution with on-board PCI-E bridge that was released in early 2008, the Radeon HD 3870 X2 and later in Radeon HD 4870 X2 graphics cards, featuring only one CrossFire connector for dual card, four GPU scalability.
