The NVIDIA GRID A100B GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.
GRID A100B Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the GRID A100B's performance in GPU benchmarks and real-world gaming. The base clock represents the minimum guaranteed frequency, while the boost clock indicates peak performance under optimal thermal conditions. Memory clock speed affects texture loading and frame buffer operations. The GRID A100B by NVIDIA dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
NVIDIA's GRID A100B Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The GRID A100B's memory capacity determines how well it handles high-resolution textures and multiple displays. Memory bandwidth, measured in GB/s, affects how quickly data moves between the GPU and VRAM. Higher bandwidth improves performance in memory-intensive scenarios like 4K gaming. The memory bus width and type (GDDR6, GDDR6X, HBM) significantly influence overall GPU benchmark scores.

About NVIDIA GRID A100B
Benchmark Performance
The NVIDIA GRID A100B presents an unusual benchmark profile. Its average benchmark score registers at zero, and its percentile ranking sits at exactly the 50th percentile of all GPUs tracked in the database. This combination indicates that the GRID A100B occupies a middle position in the overall performance distribution, though its raw compute specifications suggest a more capable part than that percentile might imply.
The data shows a significant divergence between the card's theoretical compute capabilities and its measured benchmark presence. With FP32 performance rated at 13.89 TFLOPS, the GRID A100B delivers substantial single-precision throughput. The FP16 figure of 55.57 TFLOPS (at a 4:1 ratio) represents a fourfold increase over the FP32 rate, a characteristic pattern for Ampere-generation hardware. This ratio suggests the architecture prioritizes mixed-precision workloads, which is consistent with its intended data-center orientation.
Texture and pixel processing rates further contextualize the compute figures. The card achieves 434.2 GTexel/s of texture fill rate and 193.0 GPixel/s of pixel throughput. These numbers, derived from the 432 texture mapping units and 192 raster operation units, indicate balanced geometry and fill-rate capabilities. The pixel rate, in particular, exceeds what many consumer-focused GPUs of similar vintage could sustain, though the GRID A100B's lack of display outputs means this pixel throughput serves compute workloads rather than direct rendering.
The absence of entries in the benchmarks array within the data means there are no direct score comparisons available. The nearestRivals field is likewise empty, leaving the percentile ranking as the sole comparative metric. At the 50th percentile, the GRID A100B sits at the median of all tracked GPUs, but this ranking likely reflects the breadth of the database rather than the card's absolute capability. The compute specifications would place it well above typical consumer parts, but without benchmark scores, the data cannot confirm that positioning.
How It Compares
The GRID A100B has no listed nearest rivals in the available data. This absence is notable for a product designed for virtualized infrastructure rather than direct consumer competition. The benchmark database contains no comparative scores, no deltaPct values, and no rival names to anchor its performance position.
Without nearestRivals entries, the comparison must rely on the percentile field alone. At the 50th percentile, the GRID A100B ranks exactly in the middle of all GPUs tracked. This median position is unusual for a card with 6912 shading units and 432 tensor cores, suggesting either that the database includes many high-performance parts that push the median upward, or that the GRID A100B's real-world performance in its intended workloads does not translate to the benchmark metrics used for general GPU ranking.
The production status of end-of-life further complicates any comparative analysis. As a discontinued product, the GRID A100B no longer receives driver optimizations that might improve its benchmark showing. The release date of May 13, 2020, places it in the early Ampere generation, and subsequent hardware releases have likely surpassed it in raw performance metrics. The data, however, provides no specific rival names or scores to quantify this generational gap.
Ray Tracing and Feature Set
The GRID A100B's ray tracing capabilities cannot be quantified from the available data. The rtCores field is null, meaning no dedicated ray tracing core count is listed. This absence is notable but not unexpected for a data-center-oriented GRID product, where the primary workloads involve virtualized compute and AI inference rather than real-time graphics rendering.
The tensor core configuration, however, is well documented. The card features 432 tensor cores, a substantial count that aligns with its Ampere architecture and GA100 chip design. These tensor cores enable the FP16 performance of 55.57 TFLOPS (4:1 ratio), providing the mixed-precision throughput essential for deep learning training and inference tasks. The 432 tensor cores paired with 6912 shading units create a configuration optimized for matrix operations alongside general compute.
API support is entirely absent from the data. The directx, opengl, and vulkan fields are all null. This absence suggests the GRID A100B does not prioritize traditional graphics API compatibility, consistent with its server-oriented positioning. The card has no display outputs, further confirming that its role is compute acceleration rather than rendering to a screen. The PCIe 4.0 x16 bus interface provides the host connectivity, though the data does not specify which API or compute frameworks (such as CUDA or OpenCL) are supported.

Memory Subsystem
The GRID A100B features a substantial memory configuration built around HBM2e technology. The 48 GB VRAM capacity is among the largest available in any GPU, designed to accommodate large models and datasets in virtualized environments. The memory type, HBM2e, represents the high-bandwidth variant of the second-generation HBM standard, offering improved density and efficiency over earlier HBM implementations.
The memory bus width is 6144 bit, an exceptionally wide interface that enables the card's 1.87 TB/s memory bandwidth. This figure places the GRID A100B among the highest-bandwidth GPUs in the database, with the wide bus compensating for the relatively modest memory clock of 1215 MHz (2.4 Gbps effective). The combination of 6144-bit bus and HBM2e yields a memory subsystem that can feed the 6912 shading units and 432 tensor cores without bottlenecking.
For high-resolution workloads, the memory subsystem's characteristics are decisive. The 48 GB capacity allows large framebuffers or model weights to reside entirely in VRAM, avoiding spills to system memory. The 1.87 TB/s bandwidth ensures that data movement between memory and compute units proceeds at rates sufficient to keep the tensor cores and shading units saturated. In compute scenarios involving large matrices or high-resolution textures, this bandwidth figure directly translates to throughput. The lack of display outputs means the card does not drive monitors directly, but for off-screen rendering or virtualized GPU sessions, the memory subsystem's capacity and bandwidth are the primary determinants of performance.
Power and Cooling
The GRID A100B carries a thermal design power of 400 W, a figure typical for high-performance compute accelerators of its generation. This TDP reflects the power draw of the GA100 chip with its 54,200 million transistors, manufactured on TSMC's 7 nm process. The transistor density of 65.6M per mm² on the 826 mm² die indicates a dense, power-hungry design that requires robust thermal management.
The suggested power supply is 800 W, which provides a comfortable margin above the card's 400 W TDP. This recommendation accounts for the rest of the system's power draw, including the host CPU, memory, and storage. The power connectors field is listed as "None," meaning the card does not require direct PCIe power connectors. This is characteristic of an IGP (integrated graphics processor) form factor, where power is delivered through the host system's power delivery circuitry rather than through external cables. The slot width is listed as IGP, confirming that the card is not a standard expansion card but rather an integrated module designed for server platforms.
The cooling solution is not detailed in the data, but the 400 W TDP and IGP form factor imply a passive or server-managed cooling approach. The card has no display outputs, which further indicates a rack-mounted deployment where airflow is provided by chassis fans rather than an onboard cooling solution. The power and cooling profile positions the GRID A100B as a component for dense server environments, where multiple such modules may share a single chassis and power delivery system. The 800 W PSU recommendation suggests that system builders should spec power supplies with headroom for the card's transient loads, even though the card itself does not draw power through external connectors.
