AMD has just launched the new Radeon HD 7700 series, in a bid to cement its competitiveness in the sub-$200 market-segment. The Radeon HD 7700 series, according to AMD, is designed to offer "the world's most advanced graphics for everyone." The series is based around a new ASIC built on the 28 nm fab process, codenamed "Cape Verde". The new chip takes advantage of the Graphics CoreNext architecture, and features 10 GCN compute units, amounting to 640 stream processors; 40 TMUs, and 16 ROPs; and a 128-bit wide GDDR5 memory interface.
The Radeon HD 7770 has all components on the chip enabled, and features clock speeds of 1000 MHz core, and 1125 MHz (4.50 GHz GDDR5 effective) memory, yielding 72 GB/s memory bandwidth. This card draws power from a 6-pin PCIe power connecor. The Radeon HD 7750, on the other hand, features 512 stream processors, and 32 TMUs. The rest of the specifications are identical to the HD 7770, except core clock speed: 800 MHz. The Radeon HD 7770 is priced at US $159, while the HD 7750 is available as low as $109.
