ASUS and Sapphire Rolls Out its Radeon HD 7790 Lineup


ASUS kicked off its Radeon HD 7790 lineup with custom-design implementations based on its iconic DirectCU II cooling solution. Sapphire rolled out its Radeon HD 7790 lineup with two models, both of which feature non-reference designs.

The EAH7790 DirectCU II /OC,  ships in two variants, one with stock frequencies of 1000 MHz core and 6000 MHz memory; and an OC variant with 1075 MHz core, and 6400 MHz memory. The cards use the company's dual-slot, dual-heatpipe version of DirectCU II. 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 standard variant should be priced around $149.99, the OC variant could charge $10 more.


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.
