The Intel Core i5-3320M is a fast mobile dual-core processor and is based on the Ivy Bridge architecture. Thanks to Hyperthreading, the 2 cores can process up to 4 threads simultaneously. In contrast to its predecessor Sandy Bridge, which was still produced in 32 nanometres, it is manufactured in a smaller 22 nanometre process with 3D transistors. With a clock speed of 2.6 GHz (maximum Turbo: 3.1 GHz for 2 cores, 3.3 GHz for 1 core), the i5-3320M is just below the i5-3360M (2.8 GHz) and has a 3 MB L3 cache.
Ivy Bridge is a die shrink of the Sandy Bridge architecture, which has only been improved in a few places. Among other things, PCI Express in the new version 3.0 and DDR3(L)-1600 are now supported. No changes were made to the feature set, which still includes, for example, the encryption technology AES-NI, the instruction set extension AVX and Turbo Boost 2.0.
The performance of the i5–3320M is about 5% higher than an equivalent clock model of the Sandy Bridge architecture due to minor improvements in the per–MHz performance. Compared to the i5–3360M, the processor falls back about 7% to match the previous generation i7–2640M. While the single-thread performance partly surpasses older quad-core models, an i7-2630QM is already considerably faster when all cores are utilised. Nevertheless, the performance is sufficient to master demanding applications such as HD video editing or current 3D games.
The Intel HD Graphics 4000 integrated in the processor with 16 so-called Execution Units (EUs) is responsible for the graphics output. Using Turbo mode, the output clock rate can increase from 650 MHz to 1200 MHz. The performance is about 40 % higher than that of the predecessor (HD Graphics 3000), which also matches the graphics solution of Llano (Radeon HD 6620G as the fastest model).
Like most dual-core models in the Sandy Bridge series, the i5-3320M has a TDP of 35 watts, which also includes the graphics unit.
