New details have emerged about the AMD Radeon HD 5830. The Radeon HD 5830 GPU was to have launched on January 25, 2010. As we reported earlier, the reason for the delay was that a problem on the circuitboard was triggering an error when it underwent testing. Now more details about the 5830 have been revealed. The 5830 is to have 1280 1120 unified shaders running at 750 800 MHz, 64 56 texture mapping units, 32 16 render output units, and 1 GB of GDDR5 memory running at 1 GHz. As a comparison, the more expensive 5850 has 1440 unified shaders running at 725 MHz, and 1 GB of GDDR5 memory running at 1 GHz. You will notice the specifications have changed since we last talked about the 5830, and they have not changed for the better. Meanwhile, the 5850 sells for about $310 on NewEgg (all the $300 ones are back-ordered).
