Intel Celeron 4205U
The Intel Celeron 4205U is an ULV (ultra low voltage) dual-core SoC based on the Whiskey-Lake architecture and has been launched in the first quarter of 2019. The CPU can be found in ultrabooks as well as normal notebooks. In addition to two CPU cores clocked at 1.8 GHz (no Turbo Boost, no HyperThreading), the chip also integrates an UHD Graphics 610 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The SoC is manufactured using a 14 nm++ called process with FinFET transistors.
Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before. Compared to Kaby-Lake Refresh, Whiskey Lake only offers a slightly improved manufacturing technique (14nm++ versus 14nm+).
Due to the missing Turbo Boost and the low clock speeds, especially the single thread performance is very limited which results in a lower performance even for lower demanding tasks. The performance should be on par with the Kaby Lake based Celeron 3865U that offers the same specifications. Therefore, the CPU is only suited for entry level tasks like office, web surfing and multimedia.
The integrated graphics unit called UHD Graphics 610 is similar to the HD Graphics 610 and the HD Graphics 510. The GPU represents the "GT1" version of the Whiskey Lake GPU (Intel Gen. 9). Its 12 Execution Units, also called EUs, are clocked at 300 - 900 MHz and offer a performance somewhat below the older HD Graphics 4400. Only a few games of 2018 can be played smoothly in lowest settings.
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 12.5 watts (cTDP down), reducing both heat dissipation and performance and allowing even more compact designs (but only offering 800 MHz).
