The '''Intel Celeron 3955U''' is a [[dual-core]] [[64-bit architecture|64-bit]] mobile [[microprocessor]] released by [[Intel]] in the third quarter of 2015. The 3955U is designed to replace the {{intel|Broadwell}}-based celeron. Manufactured using 14nm process, the Skylake-based 3955U Celeron processor can be configured to run at down to 10 Watt TDP. This processor, just like its predecessor lack support for any of Intel's advanced technologies such as hyper-threading, trusted execution, transactional synchronization extensions (TSX), and turbo-boost.

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.
