PowerColor X1600 XT & X1300 PRO
 

Today I have less expensive parts to test for both middle and low-end sectors of the market. They are PowerColor X1600 XT and X1300 PRO. The first card is based around RV530 core. There should be a lot of different SKUs mainly because ATI allows for handful of configurations ie. memory size and type. As far as memory bus is concerned, it features two 128-bit rings which is essentially a 128-bit architecture (ATI calls it 256, but that's obviously wrong). It comes with 4 pixel pipelines, 12 pixel shader units and 5 vertex pipelines -- not a standard 1:1 configuration. The X1300 PRO sample came in a non PRO box though based on real specifications I can assure you it's a real PRO model (just not final retail product). This baby is equipped with 4 pixel pipelines, 4 pixel shader units and 2 vertex pipelines (1 to 1 ratio, just like R520). As with X1600 XT it's also a 128-bit offering and should be available in many different configurations.
