Club3D announced its lineup of Radeon HD 7800 series graphics cards, the Radeon HD 7850 (model: CGAX-7856), and Radeon HD 7870 (CGAX-7876). Both models follow AMD reference design to the letter, there's little AIB vendor branding on these cards. The cards stick to AMD reference clock speeds, that's 1000/1200(4800) MHz (core/memory(effective)) for the HD 7870, and 860/1200(4800) MHz for the HD 7850. Based on the 28 nm "Pitcairn" silicon, the Club3D HD 7870 packs 1280 stream processors, and 2 GB of GDDR5 memory, over a 256-bit wide memory interface. The HD 7850 has 1024 stream processors. In all likelihood, Club3D's cards also stick to AMD's target pricing of US $349 for the HD 7870, and $249 for the HD 7850.
