Intel Core 2 Duo T9300 vs AMD A6-3420M
Intel Core 2 Duo T9300
► remove from comparisonThe Intel Core 2 Duo T9300 was a upper middle class dual core CPU for laptops, at the time of introduction. It is similar to the Core 2 Duo T9400 but features a slower clocked front side bus.
Due to the relatively high clock speed and 6MB Level 2 cache, the T9300 offers enough performance for most demanding games (in 2009) and applications.
The T9300 uses a Penryn (Montevina Update) core that features 2 integer units, 1 floating point unit, 1 load unit, and 1 store unit in a 14-stages long pipeline. Due to the Wide Dynamic Execution Technology, the core is able to simultaneously execute up to four instructions.
The integrated Enhanced Speedstep is able to downclock the core dynamically to save power (in idle mode).
AMD A6-3420M
► remove from comparisonThe 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.
