Intel Pentium 4405U
The Intel Pentium 4405U is an ULV (ultra low voltage) dual-core SoC based on the Skylake architecture and has been launched in September 2015. The CPU can be found in ultrabooks as well as normal notebooks. In addition to two CPU cores with Hyper-Threading clocked at 2.1 GHz (no Turbo Boost), the chip also integrates an HD Graphics 510 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The SoC is manufactured using a 14 nm process with FinFET transistors.
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").
Thnaks to the added Hyper-Threading support, the 4405U performs significantly better than previous Pentium CPUs and should match the Broadwell-based Core i3-5010U. Thus, the CPU has sufficient power for office and multimedia purposes as well as somewhat more demanding applications.
The integrated graphics unit called HD Graphics 510 represents the "GT1" version of the Skylake GPU (Intel Gen. 9). Its 12 Execution Units, also called EUs, are clocked at 300 - 950 MHz and offer a performance somewhat below the older HD Graphics 4400. Only a few games of 2015 can be played smoothly in lowest settings. For more information about performance and features, check our page for the HD Graphics 510.
Specified at a TDP of 15 W (including CPU, GPU and memory controller), the CPU is best suited for small notebooks and ultrabooks (11-inches and above). Optionally, the TDP can be lowered to 10 watts (cTDP down), reducing both heat dissipation and performance and allowing even more compact designs.
