The Single-Socket CPU That Replaces Your Dual-Socket Xeon Fleet
A dual-socket server with 2x Intel Xeon Gold 6448Y (32 それぞれのコア) delivers 64 cores at 350W combined TDP, occupying 2 CPU sockets and requiring dual-socket licensing for VMware, Windowsサーバー, and Oracle. A single-socket Dell R7715 with 1x AMD EPYC 9575F (64 コア) delivers the same core count at 400W TDP — but uses 1 ソケット, 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, 400W) | 2x Xeon 6448Y (R760, 64c, 500W combined) | Savings with EPYC |
|---|---|---|---|
| CPU Cost (estimated, per unit) | $7,500 | $6,200 ($3,100 バツ 2) | -21 パーセント (EPYC costs more per CPU) |
| VMware vSphere Ent Plus (3-年) | $5,995 (1 ソケット) | $11,990 (2 sockets) | $5,995 (50 percent savings) |
| Windows Server DC (16-core pack, 64 コア) | $24,615 (4x 16-core pack) | $24,615 (same core count) | $0 (per-core, not per-socket) |
| SQL Server Enterprise (per core, 64 コア) | $456,736 | $456,736 (same core count) | $0 (per-core) |
| Oracle DB Enterprise (per core, 64 コア) | $1,520,000 | $1,520,000 (same core count) | $0 (per-core) |
| Total 3-Year TCO (ハードウェア + ヴイエムウェア) | $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サーバー, SQLサーバー, オラクル), 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 (シングルソケット, 2う). 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 (禅 5) サポート.
