AMD Radeon HD 7900 series Specifications leaked
It is expected that AMD will announce the launch of its next generation 7000 series graphics card in the coming week. Besides that, information of the models ‘Tahiti’ and ‘New Zealand’ has got revealed, the top-end single GPU and dual GPU dedicated graphics respectively. The Radeon HD 7970 graphics would be the most powerful single GPU model of the entire Radeon HD 7000 series.
Radeon HD 7970 comes with
- 2048 shader processors
- 120 texture units
- Graphics core running at 1 GHz
- 3 GB of dedicated GDDR5 memory
- 384-bit interfacing with spectacular memory frequency of 1.37 GHz
- Memory bandwidth of a single core up to 264 GB / s
- Informal Price: $549
Radeon HD 7950 would stand a notch below the previous one but still is enthusiastic. Because it can run any current 3D game that is demanding the highest quality and resolution.
Radeon HD 7950 comes with
- 1920 would shader processors
- 900 MHz graphics core
- 2 GB of dedicated memory GDDR5
- 256-bit interface with a memory frequency of 1.25 GHz
- Informal Price: $449
The new information says that AMD will announce Tahiti in the coming week, but it will be available for retail from January, 2012.
Radeon HD 7990 Details and Specifications
Two months later, in March 2012, AMD graphics will market the dual-GPU cards derived from the above graphic cards to crush any performance test yet known. As discussed above (‘New Zealand’) Radeon HD 7990 specifications will be as double as Tahiti, that is 6 GB of dedicated memory, doubling the number of shader processors, texture units or ROPs. The starting price will be at the height of $ 799.
Further Details on HD 7000 series Graphic Cards
Besides the above said details, most of the other things are already known. HD 7000 series, which are manufactured on 28 nm are based on new architecture GCN (Graphic Core Next) and VLIW4 SIMD design, in which each packet will process four different directions at the same time exploiting the instruction-level parallelism, or whatever it is, promising great advances in GPGPU computing, as well as graphic level in all aspects.
XDR2 Memory seems to be left in HD 7900 series
Another advantage of the 7000 series is that they will use the PCIe 3.0 bus on motherboards, while the use of new memories XDR2 seems to be left for later. A Rambus memory design would offer a higher bandwidth (up to 8,000 MHz) but the cost may pile up a bit more and that’s why AMD could have been suggested to go with GDDR5 itself.
