The Radeon HD 7970 is the first of a series of upcoming graphics cards that are making the jump to the 28nm fabrication process. The new HD 7970 will effectively become AMD's new flagship single GPU graphics card come January, when the board is expected to ship.
The die shrink means AMD can cram more transistors into the same space, a lot more. Although the die size is only slightly smaller, at 365mm2 there are some 1.7 billion more transistors, taking the total count to a whopping 4.3 billion. This number whales that of the GeForce GTX 580 which boasts 3+ billion transistors in its massive 520mm2 die.
With a mere two weeks before it’ll be possible to get your hands on a new Radeon HD 7970 graphics card, it’s definitely nice to get a look now at how they perform. But before we jump into our gaming benchmarks, let’s take a moment to check out the new card's capabilities and features in greater detail.
The NVIDIA GeForce GTX 580 packs 512 CUDA cores with a graphics/processor clock of 772/1544MHz, 1.5GB of GDDR5 memory with a 384-bit interface and a data rate of 4.0Gbps. The 10.5-inch, dual-slot card draws a maximum of 244W over one 6-pin and one 8-pin PCIe connector and carries two DL-DVI outputs with one mini-HDMI port.
The NVIDIA GeForce GTX 590 measures just 11", the GeForce GTX 590 boasts 8 Graphic Processing Clusters, 32 Streaming Multiprocessors, and 1024 CUDA cores. There are also 96 ROP (Raster Operations) units and 128 TAU (Texture Addressing Units). The GeForce GTX 590 is paired with two banks of 1536MB of GDDR5 memory clocked at 1707MHz (3414MHz DDR) for a total memory capacity of 3072MB.
