A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
Level 2 (L2) Instruction and data (shared) – 1 MiB [citation needed] [original research] in size. Best access speed is around 200 GB/s [9] Level 3 (L3) Shared cache – 6 MiB [citation needed] [original research] in size. Best access speed is around 100 GB/s [9] Level 4 (L4) Shared cache – 128 MiB [citation needed] [original research] in size.
L2 cache: 1.25 MB per P-core ... μOP cache size increased to 4K entries (up from 2.25K) ... Windows 10 version 21H2 and later Windows 10 has support for Intel Thread ...
Cache hierarchy, or multi-level cache, is a memory architecture that uses a hierarchy of memory stores based on varying access speeds to cache data. Highly requested data is cached in high-speed access memory stores, allowing swifter access by central processing unit (CPU) cores.
Same frequency for all models: 2.2 GHz. L2 cache: 4.5 MB per module; each module comprises four CPU cores. SoC peripherals include 4 × USB 3.0, 4 × USB 2.0, 16 × SATA, Integrated Intel Ethernet 800 series 100 Gbit/s LAN, 3 × UART, and up to 32 lanes of PCI Express (16 × 2.0, 16 × 3.0), in x16, x8, and x4 configurations.
Lunar Lake's Lion Cove implementation contains a 2.5 MB L2 cache while the Lion Cove variant in Arrow Lake contains contains a 3 MB L2 cache. Lion Cove's larger L2 cache continues the trend of Intel increasing the size of the L2 cache for the last few generations of their P-cores such as Golden Cove, Raptor Cove and Redwood Cove. The previous ...
COASt, an acronym for "cache on a stick", is a packaging standard for modules containing SRAM used as an L2 cache in a computer. COASt modules look like somewhat oversized SIMM modules. These modules were somewhat popular in the Apple and PC platforms during early to mid-1990s, but with newer computers cache is built into either the CPU or the ...
