Sapphire Outs its Radeon HD 7790 Lineup
 

Sapphire rolled out its Radeon HD 7790 lineup with two models, both of which feature non-reference designs. The Sapphire Radeon HD 7790 (base model) features a single-fan aluminum fin-stack cooler, which utilizes a pair of 8 mm-thick copper heat pipes, AMD-reference clock speeds of 1000 MHz core, 6000 MHz memory; and a price of $149.99; while the premium Radeon HD 7790 Dual-X features a more meaty dual-fan cooling solution that uses a pair of 80 mm fans to ventilate an aluminum fin-stack, factory-overclocked speeds of 1075 MHz core, and 6400 MHz memory. Based on the 28 nm "Bonaire" silicon, the Radeon HD 7790 packs 896 stream processors, dual tessellation units, 56 TMUs, 16 ROPs, and a 128-bit GDDR5 memory interface holding 1 GB of memory; and a brand new dynamic-clock technology. The base model is priced at $149.99, the Dual-X OC at $159.99.
