To date, AMD still hasn’t released any detail about RV610. But we know that a second-generation Unified Shaders architecture will be introduced in RV610, supporting DirectX 10 and Shader Model 4.0. AMD claimed the new chip would provide a doubled performance than Radeon X1300LE. Of course, the real power is not yet to know.The RV610 has HDMI support, dual-link DVI and S-Video.
RV610 will be fabricated by TSMC with 65nm technology. Comparing with NVIDIA G86, which is fabricated by 80nm technology, although 65nm technology may help in some performance boost, its 64-bit memory bandwidth becomes a bottleneck and therefore overall weakens its performance than G86, which get the advantage from 128-bit memory bandwidth, according to a marketer.
To compensate the weak on 64-bit memory bandwidth, RV610 therefore supports DDR2, DDR3, GDDR3 and GDDR4 memory for the market need. Manufacturer may use high-speed GDDR4 for compensating the loss of performance.
ATI RV610 - native CrossFire but no 128-bit memory?
