Sa totoo lang why not get a 7000 series na dedicated VC mas ok pa sa power consumption that doing the dual.
Available on select, high-performance AMD Radeon™ HD 7000 Series graphics products, the Graphics Core Next (GCN) Architecture is a radically new approach to the design of a consumer GPU.
Most importantly, it is the world's first 28nm GPU architecture, which enables AMD to fit up to 4.3 billion transistors-the most basic building blocks of a GPU-into approximately the same space once needed to fit 2.6 billion. Increasing transistor density by greater than 60% is more than just a feat of engineering-it's responsible for the world's most powerful and advanced GPU.1
Designed to push not only the boundaries of DirectX® 11 gaming, the GCN Architecture is also AMD's first design specifically engineered for general computing. Equipped with up to 32 compute units (2048 stream processors), each containing a scalar coprocessor, AMD's 28nm GPUs are more than capable of handling workloads-and programming languages-traditionally exclusive to the processor. Coupled with the dramatic rise of GPU-aware programming languages like C++ AMP and OpenCL™, the GCN Architecture is truly the right architecture for the right time.
EfficiencyFinally, it's important that great performance and great image quality doesn't come at the expense of a high power bill. Compared to the AMD Radeon™ HD 6000 Series, products with the GCN Architecture feature reduced power consumption in the "idle state," better known as the time when you're doing desktop work. But there's more, too.
AMD ZeroCore Power TechnologyAMD ZeroCore Power Technology leverages AMD's leadership in notebook power efficiency to grant our desktop GPUs the ability to power down when your monitor is off, also known as the "long idle state."3
This is great for those times when you've stepped away from your PC to take a call, watch TV, or pop down to the store. Furthermore, AMD ZeroCore Power allows additional GPUs in an AMD CrossFire™ technology configuration to shut off when they're not in use-even the fan stops spinning!
An AMD-exclusive technology, AMD ZeroCore Power ensures that unused or idle GPUs are as efficient as possible.
Even the most hardcore gamer with an AMD CrossFire™ multi-gpu configuration benefits from AMD ZeroCore Power. Unused or idle GPUs are shut down until needed to conserve power.
