Mobile AMD Processors

Mobile AMD Processors Description

One of AMD's design goals for its Fusion architecture must have been its application in mobile processors, where AMD isn't the brightest in terms of energy efficiency. The company's fastest product for the notebook platform is based on the Llano silicon, will release in 2011, and is a quad-core APU. Enter the AMD A8-3530MX.
Built on the 32 nm process with FS1 package, the A8-3530MX is an accelerated processing unit (APU), it combines a quad-core processor with a powerful GPU and northbridge component. With a default clock speed of 1.90 GHz and TurboCore speed of 2.60 GHz, the A8-3530MX packs 4 MB of L2 cache, and a dual-channel DDR3-1600 MHz memory controller, that also supports DDR3L-1333 MHz.
The GPU component is the DirectX 11 compliant AMD Radeon HD 6620G, with 400 stream processors, and engine clock speed of 444 MHz. To drive it, the northbridge component is entirely integrated into the APU, which packs a PCI-Express 2.0 hub to support discrete graphics. Despite so much machinery, the top-of-the-line chip maintains a TDP of 45W (common for notebook quad-core chips).
The AMD A8-3530MX will be backed by a single-chip chipset, which isn't much more than a southbridge (just like PCH on the Intel platform). The platform will launch with AMD A60M chipset, and later the company will introduce A70M, which packs native USB 3.0 support. That's not to say that A60M-based notebooks won't feature USB 3.0, they'll just use third-party controllers like Intel-platform notebooks do.
