Pentium Gold 5405U is a 64-bit dual-core low-end performance x86 mobile microprocessor introduced by Intel in early 2019. This processor, which is based on an enhanced version of the Whiskey Lake microarchitecture, is manufactured on Intel's 3rd-generation enhanced 14nm++ process. The Pentium Gold 5405U operates at 2.3 GHz with a TDP of 15 W. This MPU supports up to 32 GiB of dual-channel DDR4-2400 memory and incorporates Intel's UHD Graphics 610 IGP operating at 300 MHz with a burst frequency of 950 MHz.

This model supports a configurable TDP of 12.5 W TDP-down.

Cache[edit]

[Edit/Modify Cache Info]

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
