The on-the-fly power management will let cards run cooler and quieter with reduced fan speeds when the GPU isn't running any intense 3D applications.ĪTI engineers took the opportunity to add future-anticipating DirectX 10.1 and PCI Express 2.0 support into the new chips.

Hybrid car drivers and other green-minded individuals will appreciate the Radeon HD 3800 line's new ATI PowerPlay feature, which lets the system adjust GPU clocks, memory clocks, and voltages based on GPU activity. Both cards will require an external six-pin power connector from the system power supply, which will only need to be 400W-500W for a two-card CrossFire setup and considerably less for a single card. You can combine two Radeon HD 3870 or 3850 cards in a traditional dual-card CrossFire system configuration, but the cards also have support for AMD's upcoming multi-GPU CrossFireX platform that can support two, three, or four video cards. The more powerful Radeon HD 3870 has a dual-slot cooler, whereas the Radeon HD 3850 requires only a single slot. If it makes things easier, you can think of the Radeon HD 3870 as the XT and the Radeon HD 3850 as the Pro.

ATI Radeon models will now use the last two digits of the model number to indicate the GPU variant instead of using the old Pro and XT monikers. You may have noticed that the new Radeon GPUs don't have the usual Pro, XT, or XTX designations. Mouse over each image caption to change images. AMD aims to have the ATI Radeon HD 3870 512MB available in retail at $219 and the ATI Radeon HD 3850 256MB at $179. The manufacturing improvements will let AMD reduce prices considerably from the Radeon HD 2900 XT's current $399 asking price. The new chips have the same number of stream processors as the Radeon HD 2900 XT, but are only half the size thanks to a smaller 55nm manufacturing process. Both GPUs have all the features first introduced in the Radeon HD 2000 series, including DirectX 10 support, integrated HDMI, a hardware tessellation unit, and a 512-bit internal ring bus. The new ATI Radeon HD 38 GPUs are based on an updated Radeon HD 2900 XT design. Judging by AMD's new ATI Radeon HD 3850 and ATI Radeon HD 3870 graphics processors, we're leaning toward the latter. Or maybe AMD spooked Nvidia with rumors of a new line of Radeon GPUs that are half the size of the original Radeon HD 2000 GPUs but just as powerful. Maybe Nvidia figured out that it could make more money by reducing prices and selling more chips. A company doesn't voluntarily give up hundreds of dollars in profits per unit unless there's a very good reason.
In fact, GTX chips were still on allocation, and Nvidia didn't have enough chips to fill customer orders. Why would Nvidia release a card that performs almost as well as its high-end card but charge only half the price? Demand for the GeForce 8800 GTX wasn't on the decline when Nvidia released the GeForce 8800 GT.
