The Intel Core i5-3380M is a fast dual-core processor for laptops based on the Ivy Bridge architecture. Due to Hyperthreading, the two cores can handle up to four threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.9 GHz but can dynamically increase clock rates with Turbo Boost up to 3.4 GHz (for 2 active cores) and 3.6 GHz (for 1 active core). As its predecessor Core i5-3360M, it offers a 3 MB L3-Cache.
Ivy Bridge is an enhanced die shrink of the Sandy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm (versus 32nm Sandy Bridge CPUs) and are the first to introduce 3D transistors for increased energy efficiency when compared to similarly clocked Sandy Bridge processors. Other new features are integrated PCI Express 3.0 and DDR3(L)-1600 support.
The performance of the Core i5-3380M is slightly above a similarly clocked Sandy Bridge processor due to the architectural improvements. As a result, overall performance is about 5-10 % above the old i7-2640M.
The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1250 MHz with Turbo Boost, making it one of the faster variants.
Just like most other Ivy Bridge dual-cores, the i5-3380M is rated at a TDP of 35 W. Therefore, even smaller laptops can use the Core i5.
The Intel Core i5-4300Y is an ULV (ultra low voltage) dual-core processor for ultrabooks and tablets which has been presented in Q3/2013. It is based on the Haswell architecture and manufactured in 22nm. Due to Hyperthreading, the two cores can handle up to four threads in parallel, leading to better utilization of the CPU. Each core offers a base speed of 1.6 GHz, but can dynamically increase clock rates with Turbo Boost up to 2.3 GHz.
Haswell is the successor to the Ivy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm and offer an optimized branch prediction as well as additional execution ports, improving the performance per clock by almost 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications even more.
The performance of the Core i5-4300Y is similar to the Core i3-4158U with a slightly higher TDP, assuming the Turbo Boost is working optimally. Thus, the CPU has sufficient power for office and multimedia purposes as well as most applications.
The integrated HD Graphics 4200 offers 20 Execution Units (EUs) clocked at 200 - 850 MHz with Turbo Boost, making it somewhat faster than the former HD Graphics 4000 at similar clock speeds. However, the HD 4200 is significantly slower than the HD 4400 found on other ULV models with higher clocks and TDP.
The i5-4300Y is rated at a TDP of 11.5 W (SDP 6 W) including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited for very small ultrabooks or tablets.
The Intel Core i5-4200M is a middle-class dual-core processor for laptops launched in Q2/2013. It is based on the Haswell architecture and is manufactured in 22nm. Due to Hyper-Threading, the two cores can handle up to four threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.5 GHz but can dynamically increase clock rates with Turbo Boost up to 3.1 GHz for 1 active core or 3.0 GHz for 2 active cores.
Haswell is the successor to the Ivy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm and offer an optimized branch prediction as well as additional execution ports. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.
Due to these changes, the performance per clock has been improved by almost 10 percent compared to Ivy Bridge. Therefore, the i5-4200M is about as fast as the former Ivy Bridge model i5-3340M.
The integrated Intel HD Graphics 4600 offers 20 Execution Units (EUs) clocked at 400 MHz up to 1150 MHz with Turbo Boost, making it about 30 % faster than a similarly clocked HD 4000.
The i5-4200M is rated at a TDP of 37 W including the graphics card, memory controller and VRMs. Therefore, the CPU is suited for laptops 14-inches or greater.
