Coffee Lake U (CFL-U) is the name of the core for Intel's line of low-power mobile processors based on the Coffee Lake microarchitecture serving as a successor to Kaby Lake R. These chips are primarily targeted towards light notebooks and laptops, portable all-in-ones (AiOs), minis, and conference rooms. Coffee Lake U processors are fabricated on Intel's 3rd generation enhanced 14nm++ process.

Overview

Coffee Lake U based processors are a single-chip solution - the chipset is packaged in the same physical casing as the CPU in a multi-chip package (MCP) along with the eDRAM. Communication between the separate dies are done via a lightweight On-Package Interconnect (OPI) interface, allowing for 4 GT/s transfer rate. All Coffee LAke U processors use Socket BGA-1528 and incorporate 128 MiB of side cache.

Common Features

All Coffee Lake U processors have the following:

• Dual-channel Memory
  • Up to DDR4-2400, LPDDR3-2133
  • Up to 64 GiB
• 16x PCIe
• dual-core/quad-core with 2 threads per core
• Everything up to AVX2 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX1, AVX2)
  • (Except for Pentium/Celeron which do not have AVX1/2)
• Support AHCI, High Definition Audio, 4-6x USB 3.0 ports, 8-10x USB 2.0 ports, 2-4x SATA III, 6x I2C, 3x UART, 1x SDXC
• Graphics
  • Iris Plus Graphics 655 (Gen9.5 GT3e)
  • 128 MiB of eDRAM side cache
  • 3 independent displays supported
  • Base frequency of 300 MHz
  • Burst frequency of 1.05-1.2 GHz
