Intel Core i3-4005U

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.
