Right after the PS4 reveal event ended, Sony have released a press statement that outlines the complete specifications of the system. It seems Sony are putting their all in to the PlayStation 4 with specs equivalent to a high end PC.
The press release describes the GPU and the memory as:
PS4 is equipped with 8 GB of unified system memory, easing game creation and increasing the richness of content achievable on the platform. GDDR5 is used for this memory, giving the system 176 GB/second of bandwidth and providing a further boost to graphics performance. The end result for gamers is new games with rich, high-fidelity graphics and deeply immersive experiences that shatter expectations.
The Graphics Processing Unit (GPU) has been enhanced in a number of ways, principally to allow for easier use of the GPU for general purpose computing (GPGPU) such as physics simulation. The GPU contains a unified array of 18 compute units, which collectively generate 1.84 Teraflops of processing power that can freely be applied to graphics, simulation tasks, or some mixture of the two.
The complete specification is below:
Main Processor
Single-chip custom processor
CPU : x86-64 AMD “Jaguar”, 8 cores
GPU : 1.84 TFLOPS, AMD next-generation Radeon™ based

It is interesting to see the official specs are pretty close to what we reported a week back. You can red that article over here. The only massive change is the RAM. Sony have learned their lessons and have put in a powerful 8GB GDDR5 RAM, which should make the system future proof for years.
