Benchmark Performance

The RTX A4500 delivers a 3DMark Steel Nomad DX12 score of 3196, a Geekbench OpenCL score of 141,837, and a Geekbench Vulkan score of 131,402. Aggregating these results yields an average benchmark score of 92,145, which places the card in the 95th percentile among all GPUs. This percentile ranking indicates that the RTX A4500 outperforms the vast majority of graphics cards on the market, including both consumer and professional parts. However, the data also shows that the margin over its closest competitors is slim. The nearest rival, the AMD Radeon RX 7900M, has an average score of 91,713, giving the RTX A4500 a lead of just 0.5%. The NVIDIA RTX A4500 Mobile trails by 1.1% with an average of 91,134, while the AMD Radeon Pro VII is 3.6% behind at 88,961, and the NVIDIA Quadro GP100 is 4.1% behind at 88,528. These deltas are small in absolute terms, but they consistently place the desktop RTX A4500 ahead of its nearest competitors. The 3DMark Steel Nomad score, which specifically targets DX12 workloads, reinforces the card's strong rasterization performance. Meanwhile, the Geekbench OpenCL and Vulkan scores demonstrate solid compute and graphics API performance, though the differences between the two are modest—the OpenCL result is about 7.9% higher than the Vulkan result, suggesting that the card's compute-oriented capabilities are slightly more pronounced than its immediate graphics throughput. Overall, the benchmark data indicates that the RTX A4500 is a high-performing workstation GPU, but it is not overwhelmingly faster than the closest alternatives.

How It Compares

Against the AMD Radeon RX 7900M, the RTX A4500 posts an average score of 92,145 versus 91,713, a difference of 0.5%. This is a negligible margin, effectively placing the two cards on par in synthetic benchmarks. The RX 7900M is a mobile GPU, but its average score is remarkably close to the desktop RTX A4500, suggesting that the A4500's advantage in raw performance is not substantial.

The NVIDIA RTX A4500 Mobile, which shares the same name but is a different variant, scores 91,134 on average, 1.1% lower than the desktop model. The desktop A4500's lead over its mobile counterpart is slightly larger but still modest. This indicates that the desktop version benefits from a higher power envelope and possibly better cooling, but the architectural similarities keep the performance gap narrow.

The AMD Radeon Pro VII, a workstation card from a previous generation, averages 88,961, which is 3.6% below the RTX A4500. This gap is more noticeable, and the RTX A4500's advantage likely stems from its newer architecture, higher memory bandwidth, and more advanced feature set. The Pro VII is a capable card, but the data shows the RTX A4500 holds a clear edge.

Finally, the NVIDIA Quadro GP100, an older professional GPU, scores 88,528 on average, 4.1% lower than the RTX A4500. This is the largest margin among the listed rivals, indicating that the RTX A4500 represents a meaningful generational improvement over its predecessor in terms of raw benchmark performance. While none of these deltas are dramatic, the RTX A4500 consistently outpaces all four rivals in average score.

Memory Subsystem

The RTX A4500 is equipped with 20 GB of GDDR6 memory, a substantial capacity for professional workloads. The memory interface is 320 bits wide, and the effective memory clock is 16 Gbps, yielding a bandwidth of 640.0 GB/s. This combination of capacity and bandwidth is well suited for high-resolution rendering, large dataset processing, and multi-display configurations. The 20 GB frame buffer allows the card to handle textures and geometry that would exceed the memory limits of many consumer GPUs, which typically offer 8 to 16 GB. In high-resolution scenarios, such as 4K or beyond, the ability to store more data on the card reduces the need for constant data transfers over the PCIe bus, which can become a bottleneck. The 640 GB/s bandwidth ensures that the GPU can feed its 7168 shading units and 224 texture mapping units at a rate sufficient to maintain high fill rates. The pixel rate of 158.4 GPixel/s and texture rate of 369.6 GTexel/s further underscore the card's capacity for demanding visual workloads. While the memory type is GDDR6 rather than the faster HBM2 found in some high-end workstation cards, the 20 GB capacity and 320-bit bus provide a balanced solution for most professional applications. The data indicates that the memory subsystem is a strong point of the RTX A4500, particularly for tasks that require large frame buffers.

Who Should Consider It

Based on the benchmark scores and memory characteristics, the RTX A4500 is positioned for professionals who need high compute throughput and substantial memory capacity. The 95th percentile ranking suggests that it is among the top 5% of GPUs, making it suitable for demanding tasks such as 3D rendering, scientific simulation, and machine learning inference. The 20 GB VRAM and 640 GB/s bandwidth are particularly relevant for high-resolution work; users working with 4K or higher resolution textures, complex CAD models, or multi-monitor setups will benefit from the ability to keep large datasets on the GPU. The FP32 performance of 23.65 TFLOPS, which is identical to the FP16 performance (also 23.65 TFLOPS), indicates that the card does not rely on reduced-precision acceleration for compute workloads, making it a reliable choice for applications that require full precision. The presence of 224 tensor cores further enhances its utility for AI-based tasks, though the benchmark data provided does not directly measure tensor performance. For users who require a professional-grade GPU with robust driver support and ECC memory (though ECC is not explicitly mentioned in the fact pack), the RTX A4500 is a solid option. However, the end-of-life status means that buyers should consider the availability of replacements and long-term support. In terms of resolution and settings, the data suggests the card can handle high-detail settings at 4K in many modern titles, though it is not the absolute fastest GPU available. For workstation workloads, the card's strength lies in its memory capacity and balanced compute, making it ideal for tasks that are memory-bound rather than purely rasterization-bound.

Ray Tracing and Feature Set

The RTX A4500 includes 56 ray tracing cores and 224 tensor cores, reflecting its Ampere architecture. These hardware units enable hardware-accelerated ray tracing and AI-accelerated features such as DLSS (though DLSS is not explicitly mentioned in the fact pack, the tensor cores are present). The card supports DirectX 12 Ultimate, which includes the 12_2 feature level, as well as OpenGL 4.6 and Vulkan 1.4. This API coverage ensures compatibility with modern graphics applications and game engines. The ray tracing cores deliver dedicated performance for real-time ray tracing, which is becoming increasingly important in professional visualization and rendering. The tensor cores provide support for deep learning inference and training, which can accelerate tasks like denoising and image enhancement. The FP16 compute rate of 23.65 TFLOPS is identical to the FP32 rate, indicating that the card does not offer a separate high-throughput FP16 path, but it still provides full-rate FP16 when needed. The 4x DisplayPort 1.4a outputs support high-resolution displays and multi-monitor setups, and the PCIe 4.0 x16 interface provides ample bandwidth for data transfer. The card's feature set is comprehensive for a workstation GPU, and the benchmark data, while not directly measuring ray tracing performance, indicates that the card's overall compute and graphics capabilities are strong. The inclusion of 56 RT cores is notable, as it matches the ray tracing core count of some higher-end consumer GPUs, but the card's workstation focus means it is optimized for stability and precision rather than pure gaming performance. Overall, the RTX A4500 offers a modern feature set that aligns with current professional software requirements, and its end-of-life status does not diminish its technical capabilities.
