Radeon HD 7790 Review
Radeon HD 7790 is a fast-middle-class/performance graphics card based on the 28nm, GCN architecture.
It's based on the Bonaire XT Core and therefore offer 896 Shader Processing Units, 56 TMUs and 16 ROPs on a 128-bit memory interface of fast GDDR5. The central unit runs at 1000MHz and the memory clock will operate at up to 1500MHz. It consumes up to 85 Watt.
This Graphics Card is added one year after the Radeon HD 7000 Series to compete against NVIDIA's GeForce GTX 650 Ti and benchmarks indicate its performance is between 3 and 7% better. However, NVIDIA is also set to release a new graphics card called GeForce GTX 650 Ti Boost Edition which is expected to be up to 10% better than GeForce GTX 650 Ti and so it will outperform this card.
With the release price of 150 USD, AMD's Radeon HD 7770 might become obsolete. This Graphics Card needs to be paired with a strong Dual Core CPU.
