The Radeon HD 7770 is priced at US $159, while the HD 7750 is available as low as $109. The rest of the specifications are identical to the HD 7770, except core clock speed: 800 MHz. The Radeon HD 7750, on the other hand, features 512 stream processors, and 32 TMUs. This card draws power from a 6-pin PCIe power connecor. 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. 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 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 Japanese site mentions the official launch date of HD 7800 series as being March 8, but also goes on to add that market availability (we're assuming they mean the Japanese market), is only expected on/after March 19.ĪMD has just launched the new Radeon HD 7700 series, in a bid to cement its competitiveness in the sub-$200 market-segment.

Interestingly, 2 GB is standard memory amount for both cards. the board power for the HD 7850 is mentioned to be under 130W. The slide details the HD 7850 as having 1024 stream processors, 64 TMUs, 32 ROPs, the same 256-bit GDDR5 memory interface, with the same memory clock speed as the HD 7870, but with a lower core clock speed of 860 MHz. This SKU has a typical board power of 175W. The table reveals Radeon HD 7870 as having 1280 stream processors, a 256-bit wide memory bus width (derived from the memory bandwidth and clock speeds figures provided in the table), 80 TMUs, 32 ROPs, and clock speeds of 1.00 GHz core, with 1200 MHz (4.80 GHz effective) memory. Hermitage Akihabara has not cited a source as such, so we assume it vouches for the accuracy of this table. Japanese media has got a hold of the specifications table of AMD's Radeon HD 7800 series products, the HD 7870 and HD 7850.
