AMD Radeon 5700 Series: DirectX 11 For the Mainstream


AMD today announced mid-range "ATI Radeon HD 5700" series of graphics cards supporting DirectX 11 graphics.

The new graphics cards are AMD's mainstream GPU solution (Juniper) for DirectX 11 and can be considered as a ligher version of the high-end Radeon HD 5800 series announced last month.

Both series share the same architecture and core. However, with half of the functional units left behind, the Radeon HD 5700 is left with 10 SIMDs, giving us 800 stream processors and 40 texture units, while the ROP count has also been cut in half to 16, in turn giving us a 128-bit memory bus.



The Juniper GPU is the heart of the Radeon 5770 and the 5750. The 5770 card runs at 850MHz (the same as 5850). The 5750 is slightly cut down, much like 5850 is compared to 5870. Here we have 1 SIMD disabled, and the core clock reduced to 700MHz.

Both PCI Express x16 cards support AMD's CrossFireX and Eyefinity and offer DVI?2, DisplayPort, and HDMI interfaces.

The Radeon 5770 will go on sale for about $160. The 5750 will cost you $110-130.
