The Club3D Radeon HD 6790 CoolStream Edition is based on the same Barts GPU that powers the Radeon HD 6800 series. The card is aimed at NVIDIA's recently released GTX 550, which can be found online for $130. So at least pricewise, the new Radeon HD 6790 is positioned against a GeForce GTX 460 768MB or a Radeon HD 6850 ( $160).

The 6790 is a cut-down from the 6850, losing 2 SIMD units and half of its ROPs but also features higher clockspeeds for both the core and the memory. The card has 800 SPs and 16 ROPs operating at 840MHz. It comes with 1GB GDDR5 memory clocked at 1050 MHz:
