Intel Pentium Gold 6405U
The Intel Pentium Gold 6405U is a power efficient entry-level dual-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in October 2019. Compared to the similar Whiskey Lake Pentium 5405U processors, the difference is the higher clock speed (+100 MHz) and support for faster memory. The processor cores are clocked at 2.4 GHz (no Turbo). Thanks to HyperThreading 4 threads can be used. More information on Comet Lake and all the models and articles on it can be found here.
Due to the 100 MHz higher clock speed, the Pentium Gold 6405U should be slightly faster than the old Pentium 5405U and therefore in the entry level of mobile processors. The missing Turbo and only two cores are definitely a downside and therefore the CPU is best used for simple tasks like browsing and office programs. Compared to the faster Core i3, i5 and i7 Comet Lake models, the Pentium does not support SSE (2).
The integrated graphics card is still the same as in the previous generations. It is called only Intel UHD Graphics but is still the same Intel UHD Graphics 610 like in the Pentium 5405U. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel LPDDR3-2133/DDR4-2400 memory controller (compared to DDR4-2666 in the faster Core i3).
The chip is still produced in the 14nm++ process as Whiskey Lake. The TDP (PL1) is specified at 15 Watts but can be lowered to 12.5 Watt although the CPU then only runs at 800 MHz.
