Server reviews here are built around what a chassis does under load, not what its configuration sheet allows. Systems run application workloads rather than synthetic loops alone, including HammerDB TPC-C on MariaDB, Windows Server shared storage, Proxmox Backup Server, and inference serving runs on GPU platforms. Recent coverage spans the Dell PowerEdge line, from the 1U R4715 and 2U R5715 aimed at SMB and midmarket deployments to the latency-tuned R770AP and the R7725xd that pushed past 300 GB/s of storage bandwidth in 2U, alongside dual EPYC 9005 Turin systems from Supermicro and the Lenovo ThinkSystem SR650 V4, up through the 4U-and-up GPU systems we test for AI inference. Liquid cooled and immersion designs get the same treatment, with power and thermals measured in the lab rather than quoted from a spec sheet.
If you are narrowing a shortlist, the Best Servers page ranks the current picks by role on the data from these reviews, and Best Storage Arrays covers the systems on the other side of the fabric. Our benchmark methodology explains how each workload is configured and why.
Although Dell’s PowerEdge R4715 and R5715 are two separate products, they should be viewed as a configurable matrix. The matrix includes two chassis, four AMD EPYC 9005 Series CPU options, a wide range of storage configurations, and the full Dell management and support ecosystem. The combination is purpose-built for SMB organizations that need to match
Comino recently sent us the latest version of the Comino Grando for review, configured with eight NVIDIA RTX PRO 6000 Blackwell cards, each with 96GB of VRAM, for a total of 768GB of GPU memory. We reviewed the Comino back in in 2024, configured with 6x RTX 4090s, offering 144GB of total GPU memory, as
The Dell PowerEdge R770AP is not a general-purpose server, and that is entirely the point. Where most 2U dual-socket platforms chase flexibility, the R770AP strips it away, trading GPU support, mixed storage options, and raw memory capacity for the highest core density, memory bandwidth, and execution determinism available in Dell’s current Intel lineup. It is
The PowerEdge R5715 is the second part of Dell’s SMB-focused extension to the 17th Generation PowerEdge family, starting with different priorities than its 1U sibling. Where the R4715 optimizes for compute density and core-per-rack-unit efficiency, the R5715 is built around storage capacity and I/O expandability in a 2U single-socket footprint. Readers coming from our R4715
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
The AI infrastructure market is not moving in a single direction; it is separating into two distinct worlds. On one side are frontier training clusters, built to develop foundation models at a massive scale, tightly coupled to proprietary fabrics and a narrow set of accelerators. The other is the rapidly expanding reality of enterprise inference,
We recently received Supermicro’s dual-socket Turin-based A+ Server AS-2126HS-TN for review. It’s a 2U platform designed to support extremely high-core-count workloads and to provide flexible PCIe expansion. Built around and supporting dual AMD EPYC 9005 (Turin) and 9004 (Genoa) series processors, the system targets a broad range of enterprise and data center use cases, including
The Lenovo ThinkSystem SR650 V4 is a flexible and powerful 2-socket, 2U rack server designed to meet the needs of industries such as cloud services, telecommunications, and high-performance computing (HPC). Whether optimizing for scale-out workloads or future-proofing your data center with high-density compute, the SR650 V4 offers meaningful upgrades over its predecessor, the SR650 V3.
Some servers extend what already exists, while others reset expectations. The Dell PowerEdge R7725xd belongs to the second category. In our recent testing, configured with 24 Micron 9550 PRO PCIe Gen5 NVMe SSDs and four 2x 200GbE NICs, this 2U server achieved higher raw storage throughput than any system we have measured before. Internally, the
The benefits of immersion extend beyond temperature control. With stable thermal conditions, GPUs can maintain peak boost clocks without throttling, CPUs operate with lower variability, and storage devices deliver consistent I/O throughput.
