The card is outfitted with a dual-slot cooler, but a relatively short 8.25” PCB.
With a 1GHz Cape Verde GPU paired to 1GB of GDDR5 memory clocked at 1.25GHz (4.5Gbps data rate), the Radeon HD 7770 offers up 1.28 TFLOPS of compute performance, with a texture fillrate of 40GT/s, a pixel fillrate of 16 GP/s, and peak memory bandwidth of 72GB/s.

As the full name of this card suggests, the Radeon HD 7770 GHz Edition’s GPU is clocked at a cool 1GHz-a first for a reference GPU from AMD. The Radeon HD 7770 is outfitted with a Cape Verde GPU with all of its functional units intact and enabled. The card you see here is the Radeon HD 7770 GHz Edition. With fewer stream processors, ROPs, and texture units, and a narrower memory interface, performance will be lower than Tahiti, but its features remain unchanged as you can see in the feature comparison above. According to AMD, the die size of the chip is a relatively small 123 square millimeters.Īlthough Cape Verde is pared down to target more mainstream market segments, it doesn’t skimp on any features. Cape Verde also sports 512KB of L2 R/W cache, 16 ROPs, 40 texture units, and a 128-bit GDDR5 memory interface. The Cape Verde GPU, however, is outfitted with a maximum of 640 stream processors (to Tahiti’s 2,048) arranged in 10 compute units with 64 stream processors each. Like Tahiti, Cape Verde is comprised of roughly 1.5 billion transistors and is manufactured using TSMC’s advanced 28nm process node. As we’ve mentioned, the Cape Verde GPU powering the Radeon HD 7700 series cards is based on the Graphics Core Next (GCN) architecture and has the same feature set as its higher-end counterpart found on the Radeon HD 7900 series.
