Which Dell PowerEdge Server Suits Your Needs: R660xs, R6615, or R6625?

Published by John White on 21 9 月, 2025

The Dell PowerEdge R660xs, R6615, and R6625 servers are 1U rack units designed for different workloads based on processor architecture and socket configuration. The R660xs uses dual Intel Xeon processors, the R6615 a single AMD EPYC CPU, and the R6625 dual AMD EPYC CPUs. Each server excels in specific applications from mainstream virtualization to high-performance computing.

What are the key differences in processor configurations among the R660xs, R6615, and R6625?

The Dell PowerEdge R660xs supports dual sockets for Intel’s 4th and 5th Gen Xeon Scalable processors, offering up to 32 cores per socket. The R6615 is a single-socket system based on AMD’s 4th Gen EPYC 9004 series, allowing up to 128 cores on one processor. The R6625 features dual AMD EPYC 9004 processors, each supporting up to 96 cores, providing massive parallel processing power ideal for demanding workloads.

Think of servers like high-powered workstations that run many tasks at the same time. The main part that determines how fast and how many tasks a server can handle is its processor. The Dell R660xs can hold two Intel processors, each with a moderate number of cores, which are like individual workers handling separate tasks. This setup is good for businesses that need balanced performance without extremely heavy workloads.

The R6615 and R6625, on the other hand, use AMD processors, which are known for handling a huge number of cores efficiently. The R6615 has just one processor but can pack many cores into it, making it very strong for single-CPU tasks. The R6625 can hold two AMD CPUs, each with lots of cores, giving it massive processing power for extremely demanding applications like data analysis, virtualization, or AI. Companies sourcing servers through WECENT can choose among these models depending on whether they need balanced, high-core, or ultra-high-core performance.

How does memory capacity and configuration differ between these servers?

Memory capacity scales significantly with the socket configuration. The R660xs provides 16 DDR5 DIMM slots supporting up to 1.5TB of RAM at speeds up to 5200 MT/s. The R6615 offers 12 DDR5 DIMM slots with up to 3TB RAM at speeds up to 4800 MT/s. The R6625 leads with 24 slots, supporting up to 6TB of DDR5 RAM at 4800 MT/s. The AMD-based servers support higher maximum memory due to their advanced architecture and channel configurations.

Let’s break this down in simple terms. A server’s memory is like its short-term workspace—more memory lets the server handle bigger tasks or more tasks at the same time. The number of slots in a server determines how many memory sticks you can install, which affects the total capacity.

The Dell R660xs has 16 slots and can hold up to 1.5TB of RAM, making it suitable for standard enterprise workloads. The R6615, even with only 12 slots, can reach 3TB because AMD processors allow more memory per slot thanks to their architecture. The R6625 really stands out, offering 24 slots and up to 6TB of RAM, which is ideal for heavy-duty applications like virtualization, AI, or big data. Memory speed is also important, and these servers run DDR5, with Intel slightly faster on the R660xs but AMD offering more total memory. WECENT can provide all these configurations, helping businesses match memory setup to their performance needs.

Which server offers better storage and expansion options?

All three models support up to 10 front-accessible 2.5-inch SAS, SATA, or NVMe drives, making storage flexible and performant. PCIe expansion slots vary but typically include up to 3 PCIe Gen4/Gen5 slots plus OCP 3.0 for network cards. The R660xs also has dedicated PERC RAID controller slots for enhanced storage management. Wecent emphasizes these options for tailored solutions based on workload.

Why choose the Intel-based R660xs over AMD-based R6615 or R6625 servers?

The R660xs is optimized for dense performance in mainstream applications such as virtualization and scale-out databases. Its dual Intel Xeon CPUs offer mature ecosystem support and high per-core performance. It features higher memory speed at 5200 MT/s and specialized RAID card options. This makes it well-suited for workloads needing balanced price-performance on Intel hardware.

How do workloads and use cases influence which Dell PowerEdge model to select?

The single-socket R6615 is best for cost-effective, traditional workloads and emerging ones like hyper-converged infrastructure (HCI), maximizing performance per dollar with a powerful AMD CPU. The R6625’s dual-socket AMD design fits high-performance computing (HPC), intensive virtualization, and database analytics that require high core counts and large memory. The R660xs balances performance with optimal virtualization and scale-out database support, thanks to its Intel dual-socket architecture.

What are the cooling and power supply differences among the three servers?

The R660xs uses air cooling exclusively, suitable for most data center environments. The R6615 and R6625 offer both air and Direct Liquid Cooling (DLC) options, essential for managing heat in dense, high-power AMD configurations. Power supplies come in configurations ranging from 600W to 1800W Titanium or Platinum versions across all models, supporting redundancy for enterprise reliability.
