XEON SUFFIX MEANINGS

The different letter suffixes at the end of the Xeon processor names tell you a little about the chip’s features.

  • E: Embedded
  • H: Large memory support (up to 1.12 TB per socket)
  • HL: Large memory support (up to 4.5 TB)
  • L: Large memory support (up to 4.5 TB)
  • M: Medium memory support (up to 2 TB)
  • N: Networking specialized 1)
  • P: Performance and power
  • R: Refresh (high performance)
  • S: Search optimized 2)
  • T: Thermal / long life cycle / low power 3)
  • U: Uniprocessor
  • V: Virtual machine density optimized 4)
  • Y: Speed select

gen4: Intel Xeon Scalable "Sapphire Rapids"

gen3: Gen Xeon Scalable "Ice Lake"

gen2R: gen Xeon Scalable "Cascade Lake Refresh "

gen2: gen Xeon Scalable "Cascade Lake"

gen1: Xeon Scalable "Sky Lake"

1)
NFV models are optimized for dynamic density VMs with additional headroom for higher subscribe capacity. NFV SKUs also feature speed select profiles with configurable priority based on the kind of workloads that are running.
2)
The search-optimized SKU is mainly designed for cloud search applications. Those models are designed such that they have predictable performance and latencies.
3)
Models that are suffixed with “T” have extended lifetime (10 year use) guarantees and NEBS-friendly packing specification
4)
VM density value optimized are SKUs that have been optimized to provide higher ROI for customers that benefit more from the higher thread count.
