-The different letter suffixes at the end of the Xeon processor names tell you a little about the chip’s features. +**4th Gen and 5th Gen processors use these suffixes:** 
-  * E: Embedded +  * +: Includes 1 of each of the four accelerators: DSA, IAA, QAT, DLB 
-  * H: Large memory support (up to 1.12 TB per socket) +  * H: Database and Analytics workloads 
-  * HL: Large memory support (up to 4.5 TB) +  * M: Media Transcode workloads 
-  * L: Large memory support (up to 4.5 TB) +  * N: Network/5G/Edge workloads (High TPT / Low Latency) 
-  * M: Medium memory support (up to 2 TB) +  * P: Cloud and IaaS workloads 
-  * N: Networking specialized +  * Q: Liquid cooling 
-  * P: Performance and power +  * S: Storage & HCI workloads 
-  * R: Refresh (high performance) +  * T: Long-life Use/High Tcase 
-  * S: Search optimized ((The search-optimized SKU is mainly designed for cloud search applications. Those models are designed such that they have predictable performance and latencies. There is one new search-optimized SKUs. Those models are suffixed with an ‘S’.)) +  * U: 1-socket only (some workload-specific SKUs may also be 1-socket) 
-  * T: Thermal / long life cycle / low power +  * V: Cloud and SaaS workloads 
-  * U: Uniprocessor +  * Y: SST-PP enabled (some workload-specific SKUs may also support SST-PP) 
-  * V: Virtual machine density optimized +  * Y+: SST-PP enabled and includes 1 of each of the accelerators 
-  * Y: Speed select+ 
 +**3rd Gen processors use these suffixes:** 
 +  * H: 4-Socket capable processor supporting up to 1.125TB memory per processor 
 +  * HL: 4-Socket capable processor supporting up to 4.5TB memory per processor 
 +  * M: Media Processing optimized 
 +  * N: NFV optimized 
 +  * P: High frequency-optimized for IaaS virtualization customers 
 +  * Q: Optimized for liquid cooling 
 +  * S: Large (512GB) SGX Enclave size 
 +  * T: High Tcase 
 +  * U: Single socket 
 +  * V: High density/low power-optimized for SaaS virtualization customers 
 +  * Y: Speed Select 
 + 
 +**1st Gen and 2nd Gen processors use these suffixes:** 
 +  * F: Integrated Omni-Path Architecture (OPA) Fabric 
 +  * L: Large memory tier (supports total memory up to 4.5TB per processor) 
 +  * M: Medium memory tier (supports total memory up to 2TB per Gen 2 processor or 1.5TB per Gen 1 processor) 
 +  * N: NFV optimized 
 +  * S: Search optimized 
 +  * T: High Tcase 
 +  * U: Single socket 
 +  * V: VM Density optimized 
 +  * Y: Speed Select
