About NVIDIA A100 SXM4 40 GB
The NVIDIA A100 SXM4 40 GB is an Ampere-generation server accelerator in NVIDIA's Server Ampere (Axx) family. The data records GA100 as the chip, TSMC's 7 nm process, 54,200 million transistors, an 826 mm² die, and a transistor density of 65.6M / mm². No benchmarks are populated in the dataset: the benchmarks array is empty, the average benchmark score is 0, and nearestRivals is empty. Because of that, the specification block and the percentile field carry the analysis below.
Benchmark Performance
The absence of populated benchmarks shapes this section: there are no scores to aggregate and no nearestRivals to compare against, so no deltaPct values can be reported. The percentileVsAllGpus field is 50, which places the product at the midpoint of the database's all-GPU distribution, but the 0 average benchmark score means that position is not backed by a measured result. The compute rates from the specification block are the only performance figures available: 19.49 TFLOPS FP32 and 77.97 TFLOPS FP16 (4:1). The ratio between the FP16 and FP32 entries is 4:1, reflecting the tensor-oriented throughput path. The shader and texture hardware is substantial: 6912 shading units, 432 TMUs, and 160 ROPs. Clock behavior is documented with a base of 1095 MHz and a boost of 1410 MHz. Rasterization rates are also present: 225.6 GPixel/s pixel throughput and 609.1 GTexel/s texture throughput. Without measured scores, these specification values cannot be turned into percentage deltas against named rivals.
Ray Tracing and Feature Set
The ray tracing portion of the data is empty: the rtCores field is null, so no ray tracing core count is listed. The tensor side is explicit: 432 tensor cores and 77.97 TFLOPS FP16 (4:1). The API fields are also null: DirectX, OpenGL, and Vulkan have no recorded versions. Display output is not included; the display outputs field is "No outputs". The module uses the GA100 Ampere chip, manufactured by TSMC at 7 nm. The form factor is SXM Module, and the bus interface is PCIe 4.0 x16. This combination of fields describes a server compute product rather than a display-attached graphics card.
Memory Subsystem
The memory configuration is one of the strongest parts of the specification block: 40 GB of HBM2e on a 5120-bit bus, with 1.56 TB/s of bandwidth. The memory clock is 1215 MHz, described as 2.4 Gbps effective. A 5120-bit bus and 1.56 TB/s bandwidth give the module a wide data path in the record. For high-resolution and large workload scenarios, the capacity and bandwidth are the limiting fields in the data: 40 GB determines how much data can remain resident, and 1.56 TB/s determines how fast that data can be fed to the compute units. That capacity, together with the 19.49 TFLOPS FP32 and 77.97 TFLOPS FP16 rates, indicates a memory subsystem sized for compute-heavy server work. The PCIe 4.0 x16 host interface is the connection listed for the SXM module.
How It Compares
The nearestRivals array is empty in the data, so no rival names, scores, or deltaPct values are available for this product. There are therefore no percentage comparisons to list against specific competing accelerators. The data does identify a predecessor, Tesla Turing, and a successor, Server Ada, but no benchmark scores accompany either label. This leaves percentileVsAllGpus at 50 as the only positioning metric in the data.

Who Should Consider It
The data points to a server compute module: no display outputs, SXM Module form factor, and a Server Ampere (Axx) generation label. Because the benchmark tables are empty, there are no resolution or settings scores that can ground a gaming or rendering recommendation. Instead, the relevant figures are 40 GB HBM2e, 1.56 TB/s bandwidth, 432 tensor cores, and 77.97 TFLOPS FP16 (4:1). Users with memory-capacity-heavy workloads are the clearest fit in this dataset. The 400 W TDP and 800 W suggested PSU are the planning constraints, and the production status is End-of-life. The release date is 2020-05-13. The 40 GB memory and high-bandwidth bus serve as the defining selection criteria.
Power and Cooling
The power envelope is stated as 400 W TDP, with a suggested PSU of 800 W. The power connector field is "None", meaning no supplemental connector is enumerated in the data. The physical form factor is SXM Module rather than a standard slot card; physical dimensions are not recorded. Cooling requirements are only represented through the TDP and the suggested PSU values. The module connects via PCIe 4.0 x16. It has no display outputs, so the integration path is a server or compute environment rather than a desktop display connection. End-of-life production status and the 2020-05-13 release date complete the lifecycle picture.
