# Emerald Rapids

Emerald Rapids is the codename for Intel's fifth generation Xeon Scalable server processors based on the Intel 7 node. Emerald Rapids CPUs are designed for data centers; the roughly contemporary Raptor Lake is intended for desktop and mobile usage. Nevine Nassif is a chief engineer for this generation.

## Features
### CPU

* Up to 64 Raptor Cove CPU cores per package
** Up to 32 cores per tile, reducing the max tiles to two
* 5 MB of L3 cache per core (up from 1.875 MB in Sapphire Rapids)
* Speed Select Technology that supports high and low priority cores

### I/O

* DDR5 memory support up to 8-channel DDR5-5600
* Up to 80 PCI Express 5.0 lanes
