Intel Core i3-4120U vs Intel Core i3-4158U

Intel Core i3-4120U

► remove Intel 4120U

The Intel Core i3-4120U is an ULV (ultra low voltage) dual-core processor for ultrabooks launched in Q2 2014. 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 2.0 GHz and includes no Turbo Boost support.

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 performance per clock by almost 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

According to the identical clock rate, the Core i3-4120U offers the same performance as the Core i3-4158U (28 W TDP). 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 - 1000 MHz with Turbo Boost, making it somewhat faster than the former HD Graphics 4000 at similar clock speeds. However, the HD 4400 is somewhat slower than the HD 5000 of other ULV models.

The Core i3-4120U is rated at a TDP of 15 W including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited for small ultrabooks 11-inches or greater.

Intel Core i3-4158U

► remove Intel 4158U

The Intel Core i3-4158U is a LV (low voltage) dual-core processor for large ultrabooks 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 2.0 GHz and includes no Turbo Boost support.

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 performance per clock by alomst 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

Due to these architectural improvements, the performance is slightly above a similarly clocked Ivy Bridge CPU. Therefore, the Core i3-4158U is somewhat faster than the older i3-3227U. However, when using new instruction sets 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 Iris Graphics 5100 offers 40 Execution Units (EUs) clocked at 200 - 1100 MHz with Turbo Boost, making it significantly faster than the HD Graphics 4000. As a result, the Iris Graphics competes with dedicated lower mid-range graphics cards.

The i3-4158U is rated at a TDP of 28 W including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited for larger ultrabooks 14-inches or greater.
