Intel Pentium 3561Y

The Intel Pentium 3561Y is an entry-level, ULV (ultra low voltage) dual-core processor for subnotebooks and tablets launched in Q1 2014. It is based on the Haswell architecture and is manufactured in 22nm. Compared to the Core i3, Core i5 and Core i7 CPUs, many features like Turbo Boost, Hyper-Threading and AVX are disabled. In contrast to the very similar Pentium 3560Y, the 3561Y supports Wireless Display (WiDi) and Quick Sync.

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.

The performance of the Pentium 3561Y should be 10 - 15 percent higher compared to the Ivy Bridge-based Pentium 2129Y. The CPU has sufficient power for most office and multimedia purposes, but will struggle in more demanding applications.

The integrated HD Graphics (Haswell) offers 10 Execution Units (EUs) clocked at 200 - 850 MHz with Turbo Boost, making it somewhat faster than the former HD Graphics (Ivy Bridge) at similar clock speeds. However, the HD Graphics (Haswell) is significantly slower than the HD Graphics 4400 and HD Graphics 5000 found on a number of other Haswell ULV models.

The Pentium 3561Y 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 small subnotebooks or tablets.
