Intel Pentium 4405Y

Intel 4405Y

The Intel Pentium 4405Y is a very power efficient dual-core SoC based on the Skylake architecture and has been launched in September 2015. Thanks to its extremely low TDP, the CPU can be found in passively cooled tablets and 2-in-1 notebooks. In addition to two CPU cores with Hyper-Threading clocked at 1.5 GHz (no Turbo Boost), the chip also integrates an HD Graphics GPU and a dual-channel LPDDR3-1866/DDR3L-1600 memory controller. The chip is manufactured using a 14 nm process with FinFET transistors.

Architecture

Skylake replaces both Haswell and Broadwell and brings the same microarchitecture in every TDP class from 4.5 to 45 W. The extensive improvements of the Skylake design include increased out-of-order buffers, optimized prefetching and branch prediction as well as additional performance gains through Hyper-Threading. Overall, however, performance per clock has been increased by only 5 to 10 percent (compared to Haswell) respectively under 5 percent (compard to Broadwell), which is quite modest for a new architecture ("Tock").

Performance

Actual performance of the Pentium 4405Y depends on cooling capabilities and TDP configuration of the related device. Overall, the chip should perform similar to a Core i3-4010U (Haswell, 15 W) and has sufficient power for usual office and multimedia purposes.

Graphics

The integrated graphics unit called HD Graphics (Skylake) represents the "GT1" version of the Skylake GPU (Intel Gen. 9). Its 12 Execution Units, also called EUs, are clocked at 300 - 800 MHz and offer a performance in range of the older HD Graphics 4200. Only a few older and less demanding games can be played smoothly in lowest settings. For more information about performance and features, check our page for the HD Graphics (Skylake).

Power Consumption

Specified at a TDP of 6 W (including CPU, GPU and memory controller), the CPU is suited for passively cooled notebooks and tablets. Optionally, the TDP can be lowered to 4.5 watts (cTDP down), decreasing both heat dissipation and performance.
