Intel Celeron 5205U: The Power-Efficient Dual-Core SoC for Notebooks


The Intel Celeron 5205U, a dual-core SoC for notebooks, is a new addition to the Comet Lake (CML-U) generation that was introduced in October of 2019. While it shares similarities with its predecessor, the Whiskey Lake Celeron 4205U, it boasts a more potent clock speed (+100 MHz) and the ability to support faster memory. With a clock speed of only 1.9 GHz (absent of Turbo), it is not capable of supporting SMT or HyperThreading, making it limited to 2 threads.

Despite its slight improvement over the Celeron 4205U, it is still lagging behind the old Pentium 5405U, with its 2.3 GHz clock speed and SMT capabilities. The Celeron 5205U is best suited for basic tasks such as browsing and office applications, as it falls short in comparison to the more advanced Core i3, i5, and i7 models in the Comet Lake family.

The integrated graphics card remains unchanged, being referred to as the Intel UHD Graphics but it is still the same Intel UHD Graphics 610 as in the previous generation's Pentium 4205U. Additionally, the SoC integrates a VP9 and H.265 encoder and decoder and a dual channel LPDDR3-2133/DDR4-2400 memory controller (as opposed to the DDR4-2666 in the more premium Core i3/i5/i7 processors).

In terms of power consumption, the Celeron 5205U has a default TDP (Thermal Design Power) of 15 W, although manufacturers may reduce this to a minimum of 12.5 W, leading to a reduction in performance and clock speed. Unlike other processors in the Comet Lake family, this Celeron is unlikely to exceed its power limitation as its cores are not boost-enabled.

The Celeron 5205U is manufactured using an older 14 nm process, making it less energy efficient than more recent processors. Despite this, it is a solid option for those who require basic computing needs.
