AMD EPYC Dell PowerEdge Servers: The Complete Model List

Buying guide · Updated 2026-09-18 · 12 min read

Dell uses a simple numbering rule for its PowerEdge rack line. Models ending in 0 (R770, R760, R750) are Intel; the same chassis with an AMD EPYC processor ends in 5 — the R7725 is the EPYC twin of the R770, the R7625 is the EPYC twin of the R760, and so on. The first digit marks the chassis (6 = 1U, 7 = 2U) and the middle digit marks the generation. If you are new to the generations themselves, our Dell PowerEdge generations guide explains 14G through 17G; here we focus on the AMD side of the family. You can also browse our full AMD EPYC server range.

EPYC generations at a glance

Each step moved to a newer EPYC microarchitecture, faster memory and a new PCIe generation. The 14G Naples line used DDR4-2666 and PCIe Gen3; 15G Rome/Milan moved to DDR4-3200 and PCIe Gen4; 16G Genoa introduced DDR5 and PCIe Gen5 with E3.S drives; and the newest 17G Turin line raises the memory speed to DDR5-6400 and the single-socket core ceiling to 160.

The complete table: all 16 rack-mount EPYC PowerEdge servers

Specifications are maximums from Dell official technical documentation for each model. DIMM counts, memory capacity and NVMe/E3.S limits vary by chassis configuration; exact build is confirmed at quotation.

17G EPYC (2025-2026): R6715, R6725, R7715, R7725 and R7725xd

Turin — EPYC 9005, DDR5-6400, PCIe Gen5

The newest generation is built on AMD EPYC 9005 “Turin”. It pushes the dual-socket 2U R6725/R7725 to up to 192 cores per socket, adds DDR5 at up to 6400 MT/s, up to 40 E3.S Gen5 NVMe drives in the 2U chassis and up to three 450W double-width GPUs in the single-socket R7715. The R7725xd is a storage-specialist dual-socket node with 24 U.2 Gen5 NVMe bays and no internal RAID controller (BOSS-N1 boot only). These are brand-new, current-production platforms with a 3-year manufacturer warranty.

• R7715 — the flagship single-socket 2U: up to 160 cores on one EPYC 9005 CPU, 6 TB of DDR5, 40 E3.S drives, up to 8 PCIe Gen5 slots and up to three double-width GPUs.
• R7725 — the dual-socket 2U flagship: up to 192 cores per socket, 6 TB DDR5-6400, 40 E3.S drives, the choice for the largest database and virtualization estates.
• R6715 / R6725 — the 1U versions (single- and dual-socket), up to 22 E3.S drives and three single-width GPUs for dense hosting.
• R7725xd — ultra-dense all-flash 2U storage node, 24 U.2 Gen5 NVMe bays (up to roughly 2.9 PB), GPUs not supported.

16G EPYC (2023-2024): R6615, R6625, R7615 and R7625

Genoa / Genoa-X — EPYC 9004, DDR5-4800, PCIe Gen5

The 16G generation brought AMD onto DDR5 and PCIe Gen5 with E3.S storage. Every model supports up to 128 cores per socket (EPYC 9754-class). The single-socket R6615 and R7615 use 12 DIMMs and cap at 3 TB, while the dual-socket R6625 and the in-stock PowerEdge R7625 use 24 DIMMs and reach 6 TB. These remain brand-new, factory-sealed servers with a 3-year manufacturer warranty and are the price-performance sweet spot for new EPYC builds.

15G EPYC (2021-2022): R6515, R6525, R7515 and R7525 — sealed NOS

Rome / Milan — EPYC 7002/7003, DDR4-3200, PCIe Gen4

The 15G Rome/Milan line is available from us as brand-new, factory-sealed New Old Stock rather than as used hardware. The dual-socket 2U PowerEdge R7525 and 1U PowerEdge R6525 support up to 64 cores per socket and 4 TB with LRDIMMs; the single-socket PowerEdge R7515 leads with up to 24 front NVMe bays. PCIe Gen4 and DDR4-3200 still cover the majority of virtualization, database and general workloads. Every sealed NOS unit carries a full 3-year warranty backed directly by Beijing Xinchuan Technology Co., Ltd.. Read more about what New Old Stock means.

14G EPYC (2017-2019): R6415, R7415 and R7425 — legacy reference

Naples — EPYC 7001, DDR4-2666, PCIe Gen3

The first EPYC PowerEdge models used the original EPYC 7001 “Naples” processors at up to 32 cores per socket, DDR4-2666 and PCIe Gen3. We list them for completeness and to help you identify older equipment, but we do not carry 14G as a new line. If you are evaluating a Naples-class build, a sealed 15G R6525/R7515/R7525 (Rome/Milan) or a new 16G/17G platform gives you a supported, warranted and far faster starting point.

Single-socket vs dual-socket, and 1U vs 2U

AMD's high per-socket core counts make single-socket EPYC servers unusually capable. A single-socket R7715 already provides up to 160 cores, which removes the second CPU — and its licensing and memory cost — for many workloads. Choose a dual-socket model when you need the extra memory channels, DIMM slots and PCIe lanes of a second socket. The 1U R6x15/R6x25 models maximise density in the rack; the 2U R7x15/R7x25 models add drive bays, GPU room and expansion slots. For a step-by-step method to size CPU, memory, storage and PSU, see our R760/R770 configuration guide — the same rules apply to the EPYC chassis.
