AMD is giddy as all get-out today over the arrival of its Radeon HD 7770 GHz Edition and HD 7750 graphics cards, the first of which is the world's first graphics card equipped with a 1GHz GPU, the Sunnyvale chip maker claims. The 7750's special talent is that it doesn't require its own separate power connector and pushing gaming grade pixels while staying under 75W.
"We were first to 40nm, first to 28nm and now we offer the world’s first GPU at 1GHz; this is a milestone for the graphics industry," said Matt Skynner, corporate vice president and general manager, GPU Division, AMD. "AMD continues to deliver superior performance, rich features and world-class power efficiency – we never stop innovating."
AMD's new HD 7700 Series features the chip maker's Graphics Core Next (GCN) architecture, the same as found in Tahiti, but at lower price points and with a slightly altered Compute Units arrangement. It's a new GPU known as Cape Verde that targets mainstream gamers.
The Radeon HD 7770 boasts a 1GHz engine clockspeed and 1GB of GDDR5 memory clocked at 1,125MHz on a 128-bit bus. It has 40 texture units, 16 ROPs, 1.5 billion transistors, 640 stream processors, 100W TPD, and is priced at $159.
AMD's 7750 sports a similar feature-set, but has 512 stream processors, 32 texture units, 800MHz core clockspeed, a 75W TDP, and is priced at $109.
