The Intel Core i5-4202Y is an ULV (ultra low voltage) dual-core processor for ultrabooks and tablets launched in Q3 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 2.0 GHz (2 cores: 1.7 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.
The performance of the Core i5-4202Y is similar to the Core i3-4100U with a slightly higher TDP. 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 i5-4202Y is rated at a TDP of 11.5 W (SDP 4.5 W) including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited for very small (and even passively cooled) ultrabooks or tablets.
