NVIDIA A40 PCIe Specifications
A40 PCIe GPU Core
Shader units and compute resources
The NVIDIA A40 PCIe 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.
A40 PCIe Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the A40 PCIe'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 A40 PCIe by NVIDIA dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
NVIDIA's A40 PCIe Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The A40 PCIe'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.
A40 PCIe by NVIDIA Cache
On-chip cache hierarchy
On-chip cache provides ultra-fast data access for the A40 PCIe, reducing the need to fetch data from slower VRAM. L1 and L2 caches store frequently accessed data close to the compute units. AMD's Infinity Cache (L3) dramatically increases effective bandwidth, improving GPU benchmark performance without requiring wider memory buses. Larger cache sizes help maintain high frame rates in memory-bound scenarios and reduce power consumption by minimizing VRAM accesses.
A40 PCIe Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the NVIDIA A40 PCIe against other graphics cards. FP32 (single-precision) performance, measured in TFLOPS, indicates compute capability for gaming and general GPU workloads. FP64 (double-precision) matters for scientific computing. Pixel and texture fill rates determine how quickly the GPU can render complex scenes. While real-world GPU benchmark results depend on many factors, these specifications help predict relative performance levels.
A40 PCIe Ray Tracing & AI
Hardware acceleration features
The NVIDIA A40 PCIe includes dedicated hardware for ray tracing and AI acceleration. RT cores handle real-time ray tracing calculations for realistic lighting, reflections, and shadows in supported games. Tensor cores (NVIDIA) or XMX cores (Intel) accelerate AI workloads including DLSS, FSR, and XeSS upscaling technologies. These features enable higher visual quality without proportional performance costs, making the A40 PCIe capable of delivering both stunning graphics and smooth frame rates in modern titles.
Ampere Architecture & Process
Manufacturing and design details
The NVIDIA A40 PCIe is built on NVIDIA's Ampere architecture, which defines how the GPU processes graphics and compute workloads. The manufacturing process node affects power efficiency, thermal characteristics, and maximum clock speeds. Smaller process nodes pack more transistors into the same die area, enabling higher performance per watt. Understanding the architecture helps predict how the A40 PCIe will perform in GPU benchmarks compared to previous generations.
NVIDIA's A40 PCIe Power & Thermal
TDP and power requirements
Power specifications for the NVIDIA A40 PCIe determine PSU requirements and thermal management needs. TDP (Thermal Design Power) indicates the heat output under typical loads, guiding cooler selection. Power connector requirements ensure adequate power delivery for stable operation during demanding GPU benchmarks. The suggested PSU wattage accounts for the entire system, not just the graphics card. Efficient power delivery enables the A40 PCIe to maintain boost clocks without throttling.
A40 PCIe by NVIDIA Physical & Connectivity
Dimensions and outputs
Physical dimensions of the NVIDIA A40 PCIe are critical for case compatibility. Card length, height, and slot width determine whether it fits in your chassis. The PCIe interface version affects bandwidth for communication with the CPU. Display outputs define monitor connectivity options, with modern cards supporting multiple high-resolution displays simultaneously. Verify these specifications against your case and motherboard before purchasing to ensure a proper fit.
NVIDIA API Support
Graphics and compute APIs
API support determines which games and applications can fully utilize the NVIDIA A40 PCIe. DirectX 12 Ultimate enables advanced features like ray tracing and variable rate shading. Vulkan provides cross-platform graphics capabilities with low-level hardware access. OpenGL remains important for professional applications and older games. CUDA (NVIDIA) and OpenCL enable GPU compute for video editing, 3D rendering, and scientific applications. Higher API versions unlock newer graphical features in GPU benchmarks and games.

About NVIDIA A40 PCIe
The NVIDIA A40 PCIe, built on the Ampere architecture and 8 nm process, positions itself as a high-end solution for professionals requiring robust graphical performance. With 48 GB of GDDR6 VRAM, this card caters to demanding workflows such as 3D rendering, AI training, and complex simulations, where memory capacity is critical. Its boost clock of 1740 MHz ensures dynamic performance adjustments, though the 300 WW TDP highlights significant power consumption and thermal management needs. While lacking direct benchmark comparisons, the A40 PCIe’s design prioritizes sustained workloads over gaming-centric metrics, aligning with its workstation segment placement. Prospective buyers should weigh the price-to-performance ratio carefully, as the premium cost may only be justified for specialized use cases. Longevity expectations are tied to its professional-grade build, though future-proofing depends on evolving software demands and NVIDIA’s driver support timelines.
Targeted at the workstation market, the NVIDIA A40 PCIe competes with other professional GPUs rather than consumer gaming cards, emphasizing reliability over raw frame rates. System requirements demand a PCIe 4.0 x16 slot and a high-wattage power supply, limiting compatibility with older or budget-focused motherboards. Its 48 GB VRAM buffer could extend relevance in memory-intensive applications, but general-purpose users may find this overkill compared to more affordable alternatives. The A40 PCIe’s segment placement suggests it’s best suited for enterprises or creators needing error-correcting memory and multi-monitor support for CAD, virtualization, or media workflows. Without benchmark data, comparisons rely on architectural advantages like Ampere’s RT cores and 2nd-gen DLSS, though practical gains vary by software optimization. Buyers should investigate specific application support and certifications to ensure the A40 PCIe aligns with their productivity or development pipelines.
- Assess whether your projects require 48 GB GDDR6 VRAM, as lesser workloads might not justify the NVIDIA A40 PCIe’s premium pricing.
- Verify power delivery and cooling infrastructure in your system, given the 300 WW TDP and sustained thermal output during heavy utilization.
- Compare NVIDIA A40 PCIe’s professional features like ECC memory and multi-GPU scalability against competing workstation GPUs for long-term ROI.
The NVIDIA A40 PCIe excels in niche scenarios where memory bandwidth and compute density outweigh traditional gaming metrics. Its PCIe 4.0 interface ensures low-latency data transfers, ideal for real-time collaboration tools or high-resolution video editing. However, the absence of benchmark data complicates decisions for buyers needing quantifiable performance metrics across varied workloads. Longevity hinges on NVIDIA’s commitment to driver updates and how well the A40 PCIe adapts to emerging AI and ray tracing standards. For office environments balancing cost and capability, the A40 PCIe’s segment-specific strengths may warrant investment, but only after auditing system compatibility and workflow demands. Ultimately, the NVIDIA A40 PCIe remains a compelling if specialized choice for enterprises prioritizing precision over consumer-grade versatility.
