AMD A4-3305M

AMD A4-3305M

The AMD A4-3305M (Codename Llano) is a dual-core processor for entry level laptops. It is part of the Fusion family of APUs (=Accelerated Processing Units) and features an integrated Radeon HD 6480G graphics card. The processor core is clocked at 1.9 GHz base clock speed and is able to automatically overclock up to 2.5 GHz (TurboCore, depending on temperature and used cores). 

The processor core is based on the Husky familiy 12h. Compared to the older Phenom II mobile processors, the Husky core is very similar but features an additional hardware divider. However, the performance per clock should be similar to the old Turion II, Athlon II, Phenom II mobile processors (as the Llano APU they did not feature a Level 3 cache).

The performance of the processor part is similar to a previous AMD Athlon II M320. Due to TurboCore the single threaded performance is slightly better (AMD Turion II N530 level) and the multithreaded slightly slower. Therefore, the performance is clearly worse than similar clocked Sandy Bridge based processors (e.g. Core i3-2310M).

The Llano APUs feature an integrated DirectX 11 capable graphics card with a maximum of 400 cores. The AMD Radeon HD 6480G called version in the A4-Series however offers only 160 cores at 593MHz. That is the main difference to the A4-3300M that features a "normal" 6480G with 240 shaders at 444MHz (which should be slightly faster). Both feature no dedicated memory and also are not able to use the integrated cache (in difference to the Intel HD 3000). Furthermore the APU also features an integrated UVD3 video processor to fully decode most used HD videos (like H.264, VC-1, MPEG4).

The A4-3305M also features an integrated dual-channel memory controller with support for DDR3(L)-1333 memory and a PCIe 2.0 controller.

The TDP of 35 Watt for the APU (including graphics card and memory controller) makes it best suited for 14 to 15-inch laptops.
