16-Core Intel Xeon Processors
Sixteen-core processors run through almost every modern Intel Xeon family, Xeon Silver, Gold and Platinum plus Xeon E5 v3 and v4, so a 16-core part exists for servers from the PowerEdge R630 to the R760. The family fixes the socket and memory, so pick the family your server takes before you compare clocks. Every 16-core part is tested in our lab and carries an Enterasource warranty.

16-core parts by generation and server
Sixteen cores span seven Intel generations, so the table lines up each generation with its socket, its memory and the PowerEdge models Dell lists for it:
| Generation | Socket | Memory | Dell PowerEdge |
|---|---|---|---|
| Xeon E5-2600 v3 and v4 | LGA2011-3 | DDR4 | R630 |
| Xeon Scalable, 1st and 2nd Gen | FCLGA3647 | DDR4 | R640, R740, R740xd |
| Xeon Scalable, 3rd Gen | FCLGA4189 | DDR4 | R650, R750 |
| Xeon Scalable, 4th and 5th Gen | FCLGA4677 | DDR5 | R660, R760 |
Watch the suffix: on Intel ARK a U part is a one-socket processor with no partner, so it runs only as the single CPU of a one-socket server. Intel defines the F suffix as the fabric version with an integrated Intel Omni-Path connector, so confirm an F part with your server's documentation before you order. Sixteen-core chips also come in Intel's four-socket E5-4600 and E7 families, which need servers built for them, and the Xeon E7 page covers the E7 line.
Compare 8-core, 12-core, 24-core and 32-core Xeon processors, the Xeon Silver and Xeon Gold ranges and E5-2600 v4 processors, or all Intel Xeon processors. The servers, from the PowerEdge R630 to the R760, are under Dell PowerEdge servers.
Sixteen cores and the licence floors
Sixteen is where the main per-core licences start counting. Microsoft requires Windows Server core licences for every physical core, with at least 8 per processor and 16 per server, and Broadcom rounds any CPU below 16 cores up to 16 when it counts cores for VMware. A 16-core processor is therefore licensed for exactly the cores it has, and SQL Server, licensed per core with at least four per processor, counts all sixteen. Proxmox VE subscriptions are per socket regardless of cores.
16-core Xeon questions
- Why do server licences start at 16 cores?
- Because the licensors set minimums there. Microsoft's Windows Server rules count every physical core but never fewer than 16 core licences per server, and VMware subscriptions treat each processor as having at least 16 cores. Below that, a smaller processor costs the same to license under VMware as a 16-core one, and a one-socket server still needs Windows Server's 16 core licences; Proxmox VE, licensed per socket, has no core minimum.
