The Single-Socket CPU That Replaces Your Dual-Socket Xeon Fleet

A dual-socket server with 2x Intel Xeon Gold 6448Y (32 cores each) delivers 64 cores at 350W combined TDP, occupying 2 CPU sockets and requiring dual-socket licensing for VMware, Windows Server, and Oracle. A single-socket Dell R7715 with 1x AMD EPYC 9575F (64 ядра) delivers the same core count at 400W TDP — but uses 1 socket, costs half the VMware licensing, half the Windows Server Datacenter licensing, and consumes roughly the same total power. The licensing savings alone — $6,000 for VMware vSphere Enterprise Plus, $20,000 for Windows Server Datacenter per core, and potentially millions for Oracle — pay for the server in the first year. The R7715 with EPYC 9575F is the single-socket upgrade path that makes dual-socket economics obsolete for core-constrained workloads.

EPYC 9575F vs Dual Xeon 6448Y — Single-Socket Licensing Math

Cost Category	1x EPYC 9575F (R7715, 64С, 400Вт)	2x Xeon 6448Y (760 рэндов, 64С, 500W combined)	Savings with EPYC
CPU Cost (estimated, per unit)	$7,500	$6,200 ($3,100 Икс 2)	-21 percent (EPYC costs more per CPU)
VMware vSphere Ent Plus (3-год)	$5,995 (1 socket)	$11,990 (2 sockets)	$5,995 (50 percent savings)
Windows Server DC (16-core pack, 64 ядра)	$24,615 (4x 16-core pack)	$24,615 (same core count)	$0 (per-core, not per-socket)
SQL Server Enterprise (per core, 64 ядра)	$456,736	$456,736 (same core count)	$0 (per-core)
Oracle DB Enterprise (per core, 64 ядра)	$1,520,000	$1,520,000 (same core count)	$0 (per-core)
Total 3-Year TCO (hardware + VMware)	$13,495	$18,190	$4,695 (26 percent savings)

The licensing savings are socket-dependent, not core-dependent. VMware and other per-socket license models deliver the biggest savings — 50 percent in VMware’s case. For per-core models (Windows Server, SQL-сервер, Оракул), the savings come from the R7715’s lower platform cost and single-socket infrastructure, not from the licensing. The EPYC 9575F at 3.3 GHz base clock — higher than the Xeon 6448Y at 2.1 GHz — also delivers better single-thread performance for databases and latency-sensitive workloads that care about clock speed.

Compatible Server Platform

SP5 socket, compatible with Dell PowerEdge R7715 (single-socket, 2U). Not compatible with Intel platforms or earlier EPYC generations (SP3). Verify R7715 BIOS revision supports EPYC 9575F — requires BIOS v1.4.0 or later for Turin (Zen 5) поддерживать.
