Intel Core i3-2312M vs Intel Core i3-2377M

Intel Core i3-2312M

► remove 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.

Intel Core i3-2377M

► remove Intel 2377M

The Intel Core i3-2377M is a power efficient ULV (Ultra Low Voltage) processor for thin and light laptops. The base frequency of 1.5 GHz is relatively low and the CPU does not support Turbo Boost for automatic overclocking. Due to HyperThreading, the i7-2377M is able to handle 4 threads in parallel. Compared to similar clocked Celeron and Pentium models, the i3 features the faster HD 3000 graphics card and offers more enabled features (like Quick Sync). However, compared to the expensive i7 CPUs, the i3 lacks VT-d, Trusted Execution and VPro support.

Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most notable improvements is the improved Turbo 2.0 (not used for the processing cores in the i3-2377M) and the integration of the graphics card into the 32nm CPU core.

The integrated Intel HD Graphics 3000 clocked at 350 or 1000 MHz (Turbo Boost). Due to the slower clock rate without the Turbo, compared to HD Graphics 3000 in 35W and 45W processors (usually clocked at 650 MHz base speed in non LV processors), the performance should be noticeable lower.

The performance of the CPU should be a bit higher than a similar clocked Arrandale Core i3 ULV and therefore noticeably faster than the 1.33 GHz Core i3-380UM. The average performance of the CPU part should therefore be similar to the AMD A4-3320M or Turion II M500.

The TDP of 17W (includes the integrated GPU and memory controller) allows the use of the 2377M CPU in small subnotebooks.
