AMD A4-3310MX vs AMD A6-3420M vs AMD A4-3305M

AMD A4-3310MX

► remove AMD A4-3310MX

The AMD A4-3310MX (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 2.1 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 should be comparable to a previous AMD Athlon II P340 (2.2 GHz Dual-Core). Due to TurboCore the single threaded performance should be slightly better 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 240 cores at 444MHz. It has no dedicated memory and also is 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 A4-3310MX also features an integrated dual-channel memory controller with support for DDR3(L)-1333 memory and a PCIe 2.0 controller.

The TDP of 45 Watt for the APU (including graphics card and memory controller) makes it best suited for 15-inch+ laptops.

AMD A6-3420M

► remove AMD A6-3420M

The AMD A6-3420M (Codename Llano) is a quad-core processor for entry level laptops. It is part of the Fusion family of APUs (=Accelerated Processing Units) and features an integrated Radeon HD 6520G graphics card. The processor core is clocked at 1.4 GHz base clock speed and is able to automatically overclock up to 2.4 GHz (TurboCore, depending on temperature and used cores). Compared to the A6-3410MX, the A6-3420M offers a lower base speed but a higher turbo core speed and a lower TDP rating.

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 depends on the used cores. Due to Turbo Core, a single core can be clocked up to 2.3 GHz leading to a performance of a AMD Turion II P540 (2.4 GHz 2MB L2 Cache). Using all four cores, the performance is in the range of the Phenom II X4 P920 (1.6 GHz 2MB L2 Cache). Therefore, on average a Penryn based Pentium T4500 should be comparable.

The Llano APUs feature an integrated DirectX 11 capable graphics card with a maximum of 400 cores. The AMD Radeon HD 6520G called version in the A6-Series however offers only 320 cores at 400MHz. It has no dedicated memory and also is 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 A6-3420M 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.

AMD A4-3305M

► remove 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.
