AMD Athlon II N350 vs Intel Core i3-2312M

AMD Athlon II N350

► remove from comparison

The AMD Athlon II N350 is an entry to mid range dual core processor for laptops. Compared to the faster Phenom II and Turion II processors of 2010, the Athlon II N350 features only a 64 Bit FPU (Floating Point Unit), and not 128 Bit as the Athlon II Desktop. Therefore, some rumors also indicate that the N350 could still be based on K8 parts.

The Athlon II N350 offers an integrated DDR3-1066 (or 800 according to Wikipedia) dual-channel memory controller and a 1.6 GHz HyperTransport 3.0 link (HT3200) to the chipset.

The performance of the Athlon N350 should be on par with a 2.2 GHz clocked Pentium T4400 processor of 2009. 

Intel Core i3-2312M

► remove from comparison Intel 2312M

The Intel Core i3-2310M is a dual core processor for laptops. It is based on the Sandy Bridge architecture and offers Hyperthreading to handle 4 threads at once (for a better usage of the pipeline). Compared to the faster Core i5, the i3 does not offer the Turbo Boost technique for the CPU part and is therefore clocked at 2.1 GHz (max). In difference to the similar Core i3-2310M, the 2312M can be upgraded to the Core i3-2393M which has a 400 MHz higher core frequency and a 1 MB larger last level cache than the Core i3-2312M.

Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most noteable improvements are the new 256Bit AVX instructions, the improved Turbo 2.0 and the integration of the graphics card into the 32nm CPU core. 

Der i3-2310M offers an integrated graphics card ( Intel HD Graphics 3000) which is clearly faster then the older Intel HD Graphics in the Arrandale CPUs. As the new GPU is included in the CPU, it is also manufactured in 32nm and shares the fast level 3 cache with the CPU cores (using a new ring bus). In the 2310M it is clocked from  650-1100MHz (with Turbo Boost). The faster Sandy Bridge CPUs are clocked up to 1300 MHz (like the i5-2520M). 

Furthermore, an improved dual-channel DDR3 memory controller is included on the CPU die that is used by the CPU and GPU part.

Due to the improved architecture, the average performance of the Core i3-2310M is higher than a similar clocked Arrandale Core i3 without Turbo Boost. In synthetic benchmarks, the performance was about on par with the faster clocked Core i5-430M (2.3-2.5 GHz) and therefore adequate for most applications. The performance of the 2312M is similar to the Core i3-2310M (see for benchmarks). After the upgrade to the 2393M the performance should be slightly better than the Core i3-2370M.

The 35W TDP rating includes the integrated GPU and memory controller.
