ATI Radeon HD 3650 512MB

The Sapphire Radeon HD 3650 doesn't closely resemble AMD's RV635 card reference design, as Sapphire Technology had switched from a red to blue PCB and employed an alternate cooling solution. This cooling solution actively dissipates heat from the GPU core, but unlike the reference design, it doesn't have a copper heatsink extending out to the two memory ICs next to the cooler. This cooler uses a 2-pin power connection.

While CrossFire/CrossFireX currently isn't supported under Linux, this graphics card does support ATI's multi-GPU technology with the interconnects being along the upper edge of the PCB. Samsung with a part number of K4J52324QE-BC12 manufactures the memory ICs used on the Sapphire Radeon HD 3650. No external power connector is required or present with the Radeon HD 3650.

On the backside of the graphics card are four of the Samsung memory modules with no heatsinks present. The Sapphire HD 3650 cooler is attached to the graphics card via four screws around the GPU die.

Found on the Sapphire Radeon HD 3650 are two dual-link DVI outputs (with HDCP support) and a single HDTV / video output. Like the other Radeon HD 2000/3000 graphics cards, the Radeon HD 3650 with its HDMI adapter supports audio output as well. Sapphire has placed no DisplayPort outputs on this graphics card.
