Intel Core i5-4210Y vs Intel Core i5-4210U

The Intel Core i5-4210Y 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 1.5 GHz, but can dynamically increase clock rates with Turbo Boost up to 1.9 GHz (2 cores: 1.6 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 i5-4210Y is similar to the Core i3-4010U with a slightly higher TDP of 15 W. 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 i5-4210Y is rated at a TDP of 11.5 W (SDP 6 W) including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited for very small ultrabooks or tablets.

The Intel Core i5-4210U 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 1.7 GHz, but can dynamically increase clock rates with Turbo Boost up to 2.7 GHz for 1 active core or 2.4 GHz for 2 active cores. That's exactly 100 MHz more than the i5-4200U.

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 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 i5-4210U is similar to the old and slightly higher clocked Core i5-3427U. 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 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 slightly slower than the HD 5000 found on a number of other ULV models.

Power Consumption

The i5-4210U 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.
