Dell PowerEdge R4715 Review: 1U AMD EPYC Built for the Midmarket

Enterprise  ◇  Server

Dell’s 17th Generation PowerEdge family is already well-established, and with the R4715 and R5715, the lineup now targets the SMB and midmarket segments more intentionally than before. Both servers are single-socket platforms built on the same 5th Generation AMD EPYC foundation as the broader 17th Gen family. They are tuned for organizations where right-sized core counts, licensing efficiency, and operational simplicity take priority over maximum throughput. The R4715 is a denser 1U model designed for virtualization, scale-out databases, and edge deployments. The R5715 moves to a 2U form factor, offering more drive bays and PCIe expansion, suitable for setups where storage capacity and I/O performance are key concerns.

Dell PowerEdge R4715 front

The R4715 server is positioned for organizations running virtualization, scale-out databases, and edge compute workloads where licensing efficiency and operational simplicity matter. Our review unit arrived with a single AMD EPYC 9335, the 32-core top-of-stack option for this platform, paired with 384GB of DDR5 and a BOSS RAID1 boot configuration. In addition to its 32 cores, the 9335 provides 128 MB of L3 cache and a 210W TDP. Buyers who don’t need the core count can step down to the 24-core EPYC 9255, 16-core EPYC 9135, or 8-core EPYC 9015.

A few things worth establishing up front about the platform scope: the R4715 does not support GPUs or DPUs. These are not oversights. This platform is purpose-built for CPU-centric workloads, and Dell made deliberate tradeoffs to keep the bill of materials and operational footprint in check. For workloads requiring accelerators, the R6715 and R7715 are the more appropriate models.

What the R4715 offers is a dense, air-cooled chassis with up to three PCIe Gen5 slots, 24 DDR5 RDIMM slots, and flexible 3.5-inch and 2.5-inch storage options, including U.2 NVMe. Additionally, the R4715 includes iDRAC10 with OpenManage Enterprise, and hardware-rooted security via silicon root of trust. Networking options include 25 GbE via OCP 3.0, 100 GbE and 400 GbE via PCIe AIC, Broadcom, Intel, and NVIDIA round out the NIC ecosystem; notably, no Fibre Channel connectivity is officially supported. It runs on 800W or 1100W PSUs in either Platinum or Titanium efficiency grades and supports fault-tolerant redundancy. For a value-tier server, the enterprise management and security story is largely intact.

Dell PowerEdge R4715 Build and Design

The R4715 is a 1U rack server measuring 1.68 inches tall, 18.97 inches wide, and 32.09 inches deep without the optional metal bezel (32.16 inches with the bezel). The front panel provides a power button, a system ID button, a USB 2.0 Type-A port (used with the optional LCP KVM module), a USB 2.0 Type-C port for iDRAC Direct access, and an optional MiniDisplayPort for the same KVM configuration. Drive bay latches are tool-less throughout the chassis.

Storage Configuration

The R4715 ships with three front-bay configurations: 4x 3.5-inch SAS, 8x 2.5-inch SAS/SATA, or 8x U.2 NVMe Gen4. The latter two share the same 8-bay, 2.5-inch form factor, with the backplane option determining drive-protocol support. Internal RAID is managed by either the PERC H365i or the higher-tier PERC H965i controller. OS boot utilizes a dedicated BOSS-N1 DC-MHS module, which keeps the boot volume completely separate from the data storage pool and removes the need to carve out OS space from an active array.

Cooling

The R4715 is solely air-cooled. The processor is equipped with a heatsink featuring five heat pipes and a tall fin stack that extends into the usually empty space beside the socket, increasing the surface area for heat dissipation from the CPU. Fan duty is handled by eight hot-plug high-performance fan modules arranged in sets, pushing airflow front-to-back through the chassis. There is no liquid cooling option available on this platform.

PCIe Expansion and Networking

The R4715 provides up to three PCIe Gen5 slots with x16 connectors. Slot 1 supports full-height or low-profile cards, Slot 2 supports low-profile or OCP 3.0, and Slot 4 supports full-height or low-profile cards. Two OCP NIC 3.0 slots (Slots 2 and 5, Gen5 x16) cover 1 GbE, 10 GbE, and 25 GbE adapter options. For higher bandwidth requirements, PCIe AIC NICs support up to 100 GbE and 400 GbE, with NDR VPI (400 GbE). Out-of-band management runs over a dedicated 1 Gb BMC Ethernet port, keeping management traffic entirely off the data plane. No GPU support is available on this platform.

Rear Panel

Rear I/O includes two USB 3.1 Type-A ports, one VGA port, and a dedicated 1 Gb Ethernet BMC port for iDRAC management. One additional USB 3.1 Type-A port is available internally.

iDRAC10 Management

Remote management for the R4715 uses iDRAC10, the same platform Dell ships as standard across its entire 17th-generation PowerEdge lineup, including the PowerEdge R770 and PowerEdge R7725 previously reviewed. The interface is consistent across the lineup, so administrators familiar with iDRAC on other PowerEdge servers will feel comfortable right away.

The iDRAC10 dashboard provides a comprehensive health overview of all key subsystems: System Health, Processor, Memory, Cooling, Storage, Voltages, Power Supplies, Batteries, and Intrusion Detection. The review unit shows all subsystems reporting as healthy at the time of testing. System information and firmware version details are displayed directly on the dashboard alongside the license status, which on the review unit is confirmed as Enterprise. The Task Summary panel tracks pending, in-progress, and completed jobs, with the review unit showing completed jobs from an initial provisioning cycle, including a small number with errors and one failure, typical of a new deployment.

Drilling into the System Environments section reveals cooling details, including individual fan status, PWM speeds, thermal profile settings, and inlet temperature readings, all in real time. This is particularly useful for verifying airflow in dense rack setups or for troubleshooting thermal issues without physical access to the server.

Power visibility follows the same pattern. The Power Info section breaks down PSU health, current draw, and capacity utilization alongside a rolling historical trend graph. Administrators can quickly see average and peak wattage over time, which is useful for capacity planning and spotting workload-driven power spikes without needing a separate power monitoring tool.

Together, these views make iDRAC10 a capable out-of-band management solution that covers the full operational lifecycle of the R4715, from initial deployment through daily monitoring, all accessible remotely via browser or the RESTful Redfish API.

Dell PowerEdge R4715 Performance

For performance testing of the Dell PowerEdge R4715, we compared it to its 2U counterpart, the Dell PowerEdge R5715. Both platforms share identical memory configurations and the same overall PowerEdge architecture, making them a natural comparison. The primary difference between the two review units lies in the processor choice. The R4715 came with an AMD EPYC 9335 32-core processor, while the R5715 featured an AMD EPYC 9015 8-core processor.

Dell PowerEdge R4715 and Dell PowerEdge R5715

It is worth noting that the two servers support the same EPYC 9005 Series processor lineup and can be configured with either chip depending on workload requirements. The core count delta between these two units will be reflected in the numbers, but the results reflect how each platform performs as shipped rather than a ceiling comparison between platforms.

To stress the CPUs across the systems, we used a targeted set of compute benchmarks. y-cruncher measured raw arithmetic throughput and multi-threaded floating-point performance. Blender offered a real-world rendering workload that scales with available cores and memory bandwidth. The Phoronix Test Suite complemented the benchmark set by adding a wider variety of CPU-bound workloads, providing a more complete view of sustained compute performance across both platforms.

y-cruncher

y-cruncher is a multithreaded, scalable program that can compute Pi and other mathematical constants to trillions of digits. Since its launch in 2009, it has become a popular benchmarking and stress-testing application for overclockers and hardware enthusiasts.

The R4715 consistently outperformed the R5715 across all workload sizes, completing runs roughly 2.8 to 2.9 times faster over the full range from 1 billion to 50 billion digits. At 1 billion digits, the R4715 finished in 5.305 seconds, compared to 14.537 seconds on the R5715, and the gap held steady as the workload scaled. At 50 billion digits, the R4715 reached 445.440 seconds while the R5715 required 1,273.734 seconds. The result is a direct reflection of the core count difference – the EPYC 9335 brings 32 cores against the 8-core EPYC 9015 in the R5715.

Phoronix Benchmarks

The Phoronix Test Suite is an open-source, automated benchmarking platform that supports over 450 test profiles and more than 100 test suites through OpenBenchmarking.org. It manages everything from installing dependencies to running tests and collecting results, making it perfect for performance comparisons, hardware validation, and continuous integration. We will focus on comparing the R4715 and R5715 against Stream, 7-Zip, Linux kernel build, Apache, and OpenSSL tests.

Apache web serving throughput was among the closest results in the suite, with the R4715 reaching 177,839.86 requests per second compared to 123,710.75 on the R5715. Apache can maintain reasonable throughput with fewer cores when there is sufficient memory bandwidth, resulting in a smaller gap here than with more heavily parallelized workloads.

OpenSSL transfer rate showed a wider margin, with the R4715 posting 533,318,299,283 bytes/s compared to 148,168,050,733 bytes/s on the R5715. Cryptographic throughput scales aggressively with thread count, and the separation reflects that directly.

The Linux kernel compile test produced one of the most pronounced gaps in the suite. The R4715 finished in 379.53 seconds against 1,244.86 seconds on the R5715 – kernel compilation being one of the more direct measures of how many threads a system can bring to bear simultaneously.

7-Zip compression came in at 260,124 MIPS on the R4715 versus 98,555 MIPS on the R5715, tracking consistently with the rest of the suite.

Stream memory throughput measured 370,228.9 MB/s on the R4715, compared to 230,123.6 MB/s on the R5715.

Conclusion

The Dell PowerEdge R4715 is a well-executed 1U platform that makes a clear case for a single-socket design for mainstream SMB workloads. Organizations running virtualization, scale-out databases, and edge deployments where licensing efficiency and operational simplicity take priority will find the R4715 a strong fit. The 1U footprint, three PCIe Gen5 slots, 24 DDR5 RDIMM slots, and flexible 2.5-inch and 3.5-inch storage options give the platform solid versatility without the cost overhead of a dual-socket chassis.

The performance results show what the platform is meant to do. When tested as shipped with the EPYC 9335, the R4715 consistently outperformed the R5715 across all benchmarks, with the core-count advantage most noticeable in heavily parallelized workloads such as kernel compilation, OpenSSL, and Blender. Buyers who don’t need 32 cores can choose the 24-core EPYC 9255, 16-core EPYC 9135, or 8-core EPYC 9015, selecting a processor that matches their workload and budget.

Dell PowerEdge R4715 with 17th gen servers

It’s important to clarify what the R4715 is not. It doesn’t support GPU or DPU, which are intentional tradeoffs to keep the cost and operational footprint manageable. For workloads that need accelerators, the AMD-based R6715 and R7715 are the suitable models in this lineup. Faster networking is available via PCIe AIC, supporting 100 GbE and 400 GbE options.

The R4715 consistently excels in the areas that matter most for its target use cases. These include compute density in a 1U chassis, power efficiency across 800W and 1100W Platinum and Titanium PSU options, flexible NVMe and SAS/SATA storage configurations, and a mature iDRAC10 Enterprise management experience that seamlessly integrates with the broader 17th-generation PowerEdge lineup. For SMB and midmarket buyers seeking a right-sized single-socket compute platform without overspending on storage or expansion headroom, the R4715 is an excellent choice and a natural complement to the R5715 in Dell’s current AMD-based lineup.
