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 noyaux) 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, 64C, 400O) | 2x Xeon 6448Y (R760, 64C, 500W combined) | Savings with EPYC |
|---|---|---|---|
| CPU Cost (estimated, per unit) | $7,500 | $6,200 ($3,100 X 2) | -21 percent (EPYC costs more per CPU) |
| VMware vSphere Ent Plus (3-année) | $5,995 (1 socket) | $11,990 (2 sockets) | $5,995 (50 percent savings) |
| Windows Server DC (16-core pack, 64 noyaux) | $24,615 (4x 16-core pack) | $24,615 (same core count) | $0 (per-core, not per-socket) |
| SQL Server Enterprise (per core, 64 noyaux) | $456,736 | $456,736 (same core count) | $0 (per-core) |
| Oracle DB Enterprise (per core, 64 noyaux) | $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, Serveur SQL, Oracle), 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, 2tu). 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) soutien.
