Wait – Do You Even Need Xeon 6?
It is 2026. Every vendor is pushing Xeon 6, Eカラー, PCIe Gen5, and E3.S. But here is the uncomfortable truth: for a lot of enterprise workloads, a well-configured Xeon Scalable 4th Gen server at 60% of the cost of a Xeon 6 equivalent is the smarter buy. The Dell PowerEdge R660 is that server. デュアルソケット, 32 DDR5 DIMMs, まで 12 NVMeドライブ, 3 PCIe スロット – all in 1U, at a price point that leaves budget for storage and networking instead of chasing the latest silicon.
R660 vs R670: Where Your Money Actually Goes
| What You Care About | R660 (4第 2 世代ゼオン) | R670 (ゼオン 6) | Our Take |
|---|---|---|---|
| ソケットあたりの最大コア数 | 56 | 144 (Eコア) / 86 (Pコア) | Unless you need 100+ 1U のコア数, 56 cores is rarely the bottleneck |
| Memory speed | DDR5-4800 | DDR5-6400 | Noticeable for HPC and AI. Negligible for web, AD, general virtualization |
| ドライブベイ | 8/10× 2.5インチ + 2 後方 | 8/16/20x E3.S Gen5 | E3.S is the future. U.2 NVMe is cheaper today and works everywhere |
| PCIe | 3x Gen4/Gen5 | Multi Gen5 + dual OCP | If you need 100GbE + GPU + HBA in 1U, go R670. さもないと, R660 |
| 力 (idle, dual CPU) | ~200W | ~220W | Too close to matter |
| Price delta | Baseline | +25-40% | This column decides it. That delta buys a lot of NVMe storage |
What the R660 Gets Right
DDR5 across 32 DIMM (8 最大TB) – yes, on a 4th Gen platform, you still get DDR5. まで 12 NVMe U.2 drives. PCIe Gen5 on latest motherboard revisions. The 2 rear 2.5-inch bays are underrated: boot drives that do not consume front-panel slots, keeping all 10 front bays for data. And the R660 is a known quantity – firmware is mature, drivers are established, every hypervisor and management tool has been tested against this platform for two years. In production, stability has real value.

The Jobs the R660 Does Best
- Virtualization clusters where you already own VMware licenses: 56 cores x 2 = 112 vCPUs. More than enough for 1U. Most clusters run out of memory before CPU anyway.
- Database servers needing dual-socket reliability without GPU: SQLサーバー, PostgreSQL, MySQL. 8 TB DDR5 handles all but the largest instances.
- Branch office deployments: Battle-tested, globally available, ISV-supported. Where you cannot afford compatibility surprises.
- Budget-constrained refreshes: 5 R660 nodes now beats 3 R670 nodes later – more redundancy, better workload isolation.
