The specs for Sony's successor to the Playstation brand, the PS4 will feature parts from AMD. Advanced Micro Devices are supplying both the GPU (graphics processing unit) and the CPU for the new system. The CPU, AMD's Jaguar, is 2x4 core clusters running at 1.6GHZ and providing enough multhreading power to deal with pretty much any games out there. The GPU however, uses the 'new' (AMD are working on the Radeon 8000 series for the PC) 7970M, or at least a version of it.
What are the GCN cores that make up the 7970?
The 7970 (in the PS4, the Mobile and the Desktop version all use a new AMD architecture called GCN. These GCN's are (Graphics Core Next) serve as the architectural basis for AMD's future GPUs. This is true of discrete products (such as say the version which would plug into your desktop PC's PCIE slot) and integrated solutions. These will be placed alongside the CPU - and become so called APU's. These cores are highly scalable and fantastic at compute calculations along with the traditional role of being able to push pixels onto screen - in other words, play games. This is the logical direction for AMD to go, as the market for graphic and compute functionality is becoming increasingly demanding.
7970M vs the desktop Radeon 7970
The M (meaning Mobile) is a lower power variant that you can buy for your desktop. There are a few key differences between the Desktop to Mobile (which would typically be used on say a laptop) and the version present in the PS4l. The Desktop version is more powerful - due to a number of factors. Size (both of the card and the GPU die itself) aren't such a concern. This means that heat and power draw are far less of a concern. in turn, this means AMD have managed to squeeze more onto the GPU. The desktop version comes equipped with 3GB of GDDR5 RAM, the core is running at 925MHZ, with 32 Compute Units (GCN cores), 2048 stream processors, and 32 ROPS and 128 texture units....
