Intel Core i3-4005U vs Intel Core i5-3230M vs Intel Core i3-4012Y

Intel Core i3-4005U

► remove from comparison Intel 4005U

The Intel Core i3-4005U is an ULV (ultra low voltage) dual-core processor for ultrabooks 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 1.7 GHz (no Turbo Boost support). Compared to the Core i3-4010U, the 4005U offers a slightly lower GPU clock, less I/O-ports and lacks support for VT-d.

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.

The performance of the Core i3-4005U is slightly above the old and slightly higher clocked Core i3-3217U. However, when using new instructions such as AVX2 the performance can be significantly better. Thus, the CPU has sufficient power for office and multimedia purposes as well as most applications.

The integrated HD Graphics 4400 offers 20 Execution Units (EUs) clocked at 200 - 950 MHz (with Turbo Boost), making it somewhat faster than the former HD Graphics 4000 (at similar clocks). However, the HD 4400 is significantly slower than the HD 5000 of other ULV models.

The Core i3-4005U is rated at a TDP of 15 W including graphics card, memory controller, VRMs and the integrated chipset.  Therefore, the CPU is suited for small ultrabooks 11-inches or greater.

Intel Core i5-3230M

► remove from comparison Intel 3230M

The Intel Core i5-3230M 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 2.6 GHz but can dynamically increase clock rates with Turbo Boost up to 3.0 GHz (for 2 active cores) and 3.2 GHz (for 1 active core). As its Sandy-Bridge-based predecessors, 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 i5-3230M is slightly above a similarly clocked Sandy Bridge processor due to the architectural improvements. As a result, overall performance is similar to the old i7-2620M.

The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1150 MHz with Turbo Boost, making it one of the faster variants.

Just like most other Ivy Bridge dual-cores, the i5-3230M is rated at a TDP of 35 W. Therefore, even smaller laptops can use the Core i5.

Intel Core i3-4012Y

► remove from comparison Intel 4012Y

The Intel Core i3-4012Y 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 1.5 GHz (no Turbo Boost support). Compared to the very similar Core i3-4020Y, the typical power comsuption (SDP) of the 4012Y is even lower.

Architecture

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.

Performance

The performance of the Core i3-4012Y is about 10 - 15 percent higher compared to the Ivy Bridge based Core i3-3229Y. However, performance and clock rates can be limited by the cooling capacity of very mobile devices. Overall, the CPU has sufficient power for office and multimedia purposes as well as most applications.

Graphics

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 clocks). However, the HD 4200 is significantly slower than the HD 5000 of other ULV models (with a higher TDP).

Power consumption

The i3-4012Y is rated at a TDP of 11.5 watts (SDP 4.5 watts) including graphics card, memory controller, VRMs and the integrated chipset.  Therefore, the CPU is suited for very small ultrabooks or tablets.
