Core i5-8259U is a 64-bit quad-core high-end performance x86 mobile microprocessor introduced by Intel in early 2018. This processor, which is based on the Coffee Lake microarchitecture, is manufactured on Intel's improved 14nm++ process. The i5-8259U operates at 2.3 GHz with a TDP of 28 W and with a Turbo Boost of up to 3.8 GHz. This MPU supports up to 32 GiB of dual-channel DDR4-2400 memory and incorporates Intel's Iris Plus Graphics 655 IGP operating at 300 MHz with a burst frequency of 1.05 GHz. This particular GPU includes an additional 128 MiB of eDRAM L4$.

This model has a configurable TDP-down of 20 W.

Cache

[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.
