Radeon X1650 Pro: Mainstream

ATI is also announcing a new graphics card today targeted at mainstream users, the Radeon X1650 Pro.  The new Radeon X1650 Pro is basically an evolution of the Radeon X1600 XT, but with slightly higher clock speeds and a lower introductory price-point.

ATI Radeon X1650 Pro



The Radeon X1650 Pro will be the fastest card in the Radeon X1600 family. The GPU on this card is comprised of roughly 157 million transistors, and features 12-pixel shader processors, 5-vertex shader processors, two dual-link DVI outputs, a single-slot cooler, and a 128-bit 4-channel memory interface.  The Radeon X1650 Pro sports 256MB of RAM clocked at 1.4GHz and a GPU core clocked at 600MHz.  The Radeon X1600 XT - formerly the fastest of the X1600-based cards - shipped with its GPU clocked at 590MHz and its RAM clocked at 1.38GHz. The X1650 Pro's slight clock speed boost give it a slight edge in performance over the XT.


The Radeon X1650 Pro we tested came by way of Sapphire Tech.  For all intents and purposes, the Sapphire Radeon X1650 Pro will be identical to a "Built-by-ATI" card in just about every way except for its bundle. Sapphire ships their card with a complete user's manual, a driver / utility CD, an HD component output dongle, a composite video cable, an S-Video to RCA adapter, and a DVI-to-DB15 monitor adapter.  ATI-built versions of the card will likely feature a more subdued bundle if history is any indicator.
