The Inspur NF5488A5 is a 4U server platform validated by NVIDIA for HGX A100 with eight GPUs. Its defining feature is not simply the number of accelerators: the system manual specifies A100 SXM4 modules, while NVIDIA’s eight-GPU HGX design uses NVSwitch to interconnect them. Exact CPU, memory, storage, networking, GPU-memory capacity and warranty depend on the configuration being offered.
This is a documentation-based platform review, not a hands-on performance review. NVIDIA’s published HGX specifications describe the platform design; they are not benchmark results measured on an NF5488A5.
What is the Inspur NF5488A5?
The NF5488A5 is an enterprise 4U rack server designed to host eight NVIDIA A100 SXM4 accelerators in an HGX A100 configuration. NVIDIA’s certification record lists the NF5488A5 as an HGX A100 8-GPU system and identifies bare-metal compatibility. That validates the platform category, but it does not specify the parts in an individual unit. NVIDIA certified systems

NF5488A5 specifications and configuration
The Inspur manual describes a dual-socket platform with AMD EPYC Rome- or Milan-generation processors, eight A100 SXM4 GPUs, and DDR4 memory. The listed component limits describe supported configurations, not necessarily the configuration in a used server. Inspur NF5488A5 manual
| Component | Documented platform detail |
|---|---|
| Form factor | 4U rack server (Inspur manual) |
| Processors | Two AMD EPYC Rome or Milan processors; manual excerpt lists a 225–240 W TDP range (Inspur manual) |
| System memory | DDR4 RDIMM or LRDIMM at up to 3200 MHz; up to 2 TB (Inspur manual) |
| Accelerators | Eight NVIDIA A100 SXM4 GPUs, offered in 40 GB or 80 GB variants; up to 400 W listed per GPU (Inspur manual) |
| Drives and networking | Configuration-dependent; the manual’s listed platform limits do not identify the parts installed in a particular unit |
These figures are platform support details rather than a guarantee that every NF5488A5 contains the maximum configuration. Ask for the exact CPU model and pair, total RAM, GPU memory per card, installed drives and network adapters, and the server’s firmware and condition.
What eight-GPU HGX A100 adds
HGX is NVIDIA’s accelerator platform design, including the high-speed GPU interconnect. NVIDIA’s software guide says the eight-GPU HGX A100 configuration is interconnected with NVSwitch. Its four-GPU configuration, by contrast, uses a fully connected NVLink arrangement. NVIDIA HGX A100 Software User Guide
For the eight-GPU version, NVIDIA’s 2020 HGX A100 datasheet lists up to 640 GB of aggregate GPU memory, 600 GB/s GPU-to-GPU bandwidth and 4.8 TB/s aggregate bandwidth. The same sheet lists peak figures of 156 TF FP64, 2.5 PF TF32, 5 PF FP16 and 10 POPS INT8; figures marked with an asterisk use sparsity. These are NVIDIA platform specifications, not NF5488A5 test results. NVIDIA HGX A100 datasheet

Workload throughput can vary with the GPU memory version, precision, sparsity, model and data, software stack, host configuration, network fabric and power or cooling limits. No system-specific NF5488A5 benchmark, wall-power measurement, acoustic result or thermal test is established here. The platform figures above explain the interconnect and theoretical design capability, not what a particular workload will achieve.
A100 SXM4 versus PCIe: which specifications apply?
The NF5488A5 manual specifies SXM4 GPUs, so comparisons should use NVIDIA’s SXM specifications rather than assume the server has PCIe add-in cards. NVIDIA’s A100 datasheet distinguishes the 80 GB SXM and PCIe versions: each has 80 GB of HBM2e, but the SXM version is rated for up to 2,039 GB/s memory bandwidth and 400 W standard TDP, while the PCIe version is rated for up to 1,935 GB/s and 300 W. NVIDIA lists up to 600 GB/s NVLink for SXM through HGX; PCIe A100 connects through NVLink Bridge for up to two GPUs. These are NVIDIA’s published specifications, not NF5488A5 measurements. NVIDIA A100 datasheet
That distinction matters when assessing a listing or comparing systems: a server with eight SXM accelerators and NVSwitch is not interchangeable with a collection of PCIe A100 cards simply because both use the A100 name. Confirm that the offered unit is actually equipped with the stated SXM4 GPUs.
GPU memory and MIG
Eight 80 GB A100 SXM GPUs provide up to 640 GB of aggregate GPU memory; eight 40 GB cards provide 320 GB. Aggregate capacity does not mean that a single GPU has that much local memory. Model placement, parallelism and the software stack determine how a workload can use memory distributed across GPUs.

A reseller listing available through a quote request showed a used NF5488A5 with eight 80 GB A100-SXM4 GPUs and two AMD EPYC 7713 processors. The indexed listing gave an availability date of September 4, 2026, but no comparable published price. This is evidence of one seller’s stated configuration, not a stable market price or proof that the same inventory remains available. IT Creations NF5488A5 listing

Because this is a high-power 4U accelerator server, confirm that the intended rack, facility power, cooling and network fabric can accommodate the offered configuration. The cited platform documentation does not establish a single deployment requirement that applies to every workload or facility, so obtain those requirements for the actual build and operating environment rather than relying on a generic estimate.
Who should consider this platform?
The NF5488A5 is worth evaluating when a project specifically needs an eight-GPU A100 SXM/HGX system and can support enterprise rack hardware. NVSwitch and the HGX topology are relevant to multi-GPU workloads that need fast GPU-to-GPU communication, but the presence of that interconnect alone cannot predict application performance.
It is a less straightforward choice when the buyer needs a known out-of-box configuration, a public fixed price, or performance evidence for a particular workload. In those cases, make the vendor quote and acceptance criteria configuration-specific: identify the software and workload to validate, and agree on what test results, support and return terms the seller will provide. No universally superior alternative or current street-price comparison is established by the available product evidence.
