Intel Core i5-4278U vs Intel Core i5-4402E

Intel Core i5-4278U

► remove Intel 4278U

The Intel Core i5-4278U is a LV (low voltage) dual-core processor for large ultrabooks launched in Q3 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 2.6 GHz, but can dynamically increase clock rates with Turbo Boost up to 3.1 GHz.

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

Due to these architectural improvements, the performance is slightly above a similarly clocked Ivy Bridge CPU. Therefore, the Core i5-4278U is almost as fast as the older i7-3520M. 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 more demanding applications.

Graphics

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 (e.g. GeForce GT 720M). However, even fast dual-channel memory limits the performance.

Power Consumption

The i5-4278U 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, well-cooled ultrabooks.

Intel Core i5-4402E

► remove Intel 4402E

The Intel Core i5-4402E is a dual-core processor for embedded systems launched in mid-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 1.6 GHz, but can dynamically increase clock rates with Turbo Boost up to 2.7 GHz for 1 active core. The memory controller supports ECC.

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 i5-4402E is similar to the consumer model Core i5-4200U with slighty lower clock rates.

The integrated graphics card offers 20 Execution Units (EUs), which represents the GT2 version of the Haswell GPU. Technically, the GPU is the same Intel HD Graphics 4600 found on other Core i5 CPUs, but the clock rate of 400 - 900 MHz is noticeably lower.

The i5-4402E is rated at a TDP of 25 W including the graphics card, memory controller and VRMs.
