AMD has added a third sub-$100 graphics card to its DirectX 11 lineup. The new Radeon HD 5570 fits squarely between the recently released Radeon HD 5670 and the Radeon HD 5450 with a $79-85 suggested price range.
The ATI Radeon HD 5570 graphics card is an energy efficient, low-profile DirectX 11 card for small form factor PCs. It fully supports ATI Eyefinity multi-display technology and ATI Stream capabilities.
"Customers purchasing small form factor PCs are looking for improved performance while gaming, watching HD video or working with the latest productivity applications. The ATI Radeon HD 5570 graphics card delivers all of this at a price that won't break the bank," said Matt Skynner, vice president and general manager, AMD Graphics Division.
The ATI Radeon HD 5570 also delivers full 1080p HD playback and supports ATI Stream technology, helping to boost performance for video playback and productivity applications, all while enabling a full Microsoft Windows 7 experience.
The ATI Radeon HD 5570 graphics card provides great game play in DirectX 11 titles such as Codemaster's Colin McRae: DiRT 2, EA Phenomic's BattleForge , GSC Game World's S.T.A.L.K.E.R: Call of Pripyat and Battlefield: Bad Company 2 as well as DirectX 9, DirectX 10, DirectX 10.1 and OpenGL titles. The new card delivers up to a 60 percent performance improvement over the closest competing product in its class (Nvidia GeForce GT 220), AMD claims.
AMD based the Radeon HD 5570 on the same 40-nm Redwood graphics processor that powers the 5670. Users will get 400 stream processors, five texture units (for 20 texels/clock fill rate), two ROP units (for a total eight pixels per clock), and a 128-bit memory interface. However, the core clock speed has fallen from 775MHz to 650MHz, and instead of 4Gbps GDDR5, AMD has limited the 5570's memory selection to 1.8Gbps DDR3.
As a result, floating-point number crunching power has fallen from 620 gigaFLOPS on the Radeon HD 5670 to 520 gigaFLOPS on the Radeon HD 5570, and memory bandwidth has dropped similarly from 64GB/s to just 28.8GB/s.
The ATI Radeon HD 5570 graphics card comes with an HDMI 1.3a with Dolby TrueHD and DTS-HD Master Audio for a premium media PC experience.
