Dell PowerEdge R6725
What Is the Dell PowerEdge R6725?
The R6725 is the dual-CPU 1U member of Dell’s 17th-generation PowerEdge family on AMD’s EPYC 9005 “Turin” (Zen 5) platform. Two SP5 processors expose 24 DDR5 memory channels and, with the highest-density Turin parts, up to 192 cores in each socket — a system maximum of 384 cores inside a single 1U chassis. Dell launched the R6725 in 2025 alongside the single-socket 1U R6715 and the 2U R7715/R7725, succeeding the 16th-generation R6625.
The 1U body accepts 8 or 10 front 2.5″ bays (up to 8 NVMe), 8 or 16 front E3.S bays (up to 8 NVMe) or 4 front 3.5″ bays, plus up to two rear 2.5″ or E3.S drives — a maximum of 22 E3.S PCIe Gen5 NVMe drives. Expansion runs to four front Gen5 x16 slots plus one x8, two rear Gen5 x16 slots and two OCP 3.0 connections, with PERC H965i/H975i RAID, HBA465e external connectivity, BOSS-N1 redundant boot, iDRAC10 management and Quick Sync 2 wireless provisioning. It is a current platform: parts, firmware and the manufacturer warranty are all first-line.

Why Choose a Dual-Socket 1U Turin Server?
The R6725 is the right tool when rack space is the constraint and the workload genuinely scales across both sockets:
- Extreme compute density per U. Up to 384 Zen 5 cores in a 1U node means more threads, VMs and HPC jobs per rack than any single-socket or 16G 1U platform.
- Huge, fast memory in a 1U body. 24 channels of DDR5-6400 and up to 6 TB of capacity feed in-memory databases, large hypervisor hosts and memory-bound analytics without moving to a 2U chassis.
- Full Gen5 I/O, kept compact. Up to 22 E3.S Gen5 NVMe drives, four front Gen5 x16 slots and two OCP 3.0 links give an all-flash 1U node room for high-speed networking and software-defined storage.
- Two sockets, one balanced design. Each CPU owns 12 memory channels and half the expansion — a clean dual-NUMA topology that modern hypervisors and Linux distributions schedule efficiently.
If you do not need the second socket, the single-socket R6715 keeps the same 1U Gen5 platform and the same 22-drive E3.S ceiling while buying and licensing one CPU. Choose the R6725 when the second socket’s cores and the DDR5-6400 dual-socket bandwidth are actually on the bill of materials.
Where the R6725 Fits
HPC & throughput computing
Up to 384 Zen 5 cores per 1U node for tightly packed parallel jobs, batch farms, rendering, simulation and licence-dense compute clusters.
High-density virtualization
Two Turin CPUs, 24 DDR5-6400 DIMMs and Gen5 I/O run very high VM-density vSphere, Hyper-V and KVM hosts where rack units are scarce.
In-memory & memory-bound workloads
Up to 6 TB across 24 channels at 6400 MT/s for large in-memory databases, caching tiers and analytics that value bandwidth over disk bays.
All-flash 1U HCI & SDS nodes
Up to 22 E3.S Gen5 NVMe drives and two OCP 3.0 links for compact vSAN, Ceph and Proxmox nodes with fast east-west networking.

R6725 vs R6715: both are 17th-gen 1U Turin servers with the same 22-drive E3.S ceiling and the same single-width GPU envelope. The difference is sockets: the R6725 runs two CPUs for up to 384 cores and DDR5-6400 up to 6 TB, while the R6715 runs one CPU for up to 160 cores and DDR5-5200 up to 3 TB. If your workload and software licensing do not fill the second socket, the R6715 delivers most of the platform for less licence cost. Browse the full AMD EPYC model list and our other EPYC servers.
R6725 vs R6625: stepping up from the 16th generation doubles the 1U core ceiling (384 vs 192), moves memory from DDR5-4800 to DDR5-6400 and brings the PERC H975i controller, iDRAC10 and Quick Sync 2 generation. If you want the current dual-socket 1U platform with the longest support runway, the R6725 is the choice; the R6625 remains a proven previous-generation value platform.
When to Step Up to the 2U R7725
The R6725 maximizes dual-socket compute and memory per rack unit; 1U thermals cap GPUs at three 75 W single-width cards and flash at 22 E3.S drives. If you need double-width accelerators or more drive bays, choose the 2U Dell PowerEdge R7725: the same dual Turin platform with up to 40 E3.S Gen5 NVMe drives and up to two double-width plus six single-width GPUs. Rule: R6725 for cores and memory per U, R7725 for drives and GPUs.

Is the R6725 single-socket or dual-socket, and how many cores does it have?
The R6725 is dual-socket: it takes two AMD EPYC 9005 Turin processors, with up to 192 cores on each socket and up to 384 cores in total. The single-socket 17th-generation 1U model is the R6715, which supports up to 160 cores in one CPU. The two sockets together provide 24 DDR5 channels (12 per socket), 24 DIMMs at up to 6400 MT/s and up to 6 TB of memory.
R6725 vs R6715 — which should I choose?
Choose the R6725 if you genuinely need up to 384 cores, dual-socket DDR5-6400 bandwidth and up to 6 TB of memory, and will licence both CPUs. Choose the R6715 if you want the same 1U 17G platform and the same 22-drive E3.S ceiling while buying and licensing a single socket; the R6715 tops out at 160 cores and DDR5-5200 up to 3 TB. Workloads that do not fully use a second socket are cheaper to licence on the R6715.
R6725 vs R6625 — is the 17th-generation upgrade worth it?
The R6625 is the 16th-generation dual-socket 1U server on EPYC 9004 (Zen 4), with up to 96 cores per socket and 192 in total and DDR5-4800 memory. The R6725 moves to Zen 5 Turin with up to 192 cores per socket and 384 total, DDR5-6400 up to 6 TB, up to 22 E3.S Gen5 NVMe drives, the PERC H975i controller and iDRAC10. For the longest support life and the highest dual-socket compute density in 1U, the R6725 is the current choice; the R6625 remains a proven previous-generation option.
What memory and storage does the R6725 support?
