NVIDIA RTX A5000

The NVIDIA RTX A5000 is a workstation GPU built on the Ampere architecture, using the GA102 chip fabricated on Samsung's 8 nm process. It integrates 28,300 million transistors on a 628 mm² die and features 8,192 shading units, 256 texture mapping units, and 96 render output units. The card is equipped with 24 GB of GDDR6 memory on a 384-bit bus, delivering 768.0 GB/s of bandwidth. Its average benchmark score across a suite of tests is 33,294, placing it in the 77th percentile of all GPUs. This analysis positions the A5000 against its nearest rivals and examines its feature set and performance characteristics.

How It Compares

The AMD Radeon Pro 570 posts an average score of 33,258, which is 0.1% lower than the A5000's 33,294. This delta is negligible, indicating that the two cards are statistically tied in aggregate performance. The A5000's lead is marginal, and in real-world workloads, the difference would be imperceptible. Both are workstation-oriented, but the A5000's larger memory and higher bandwidth may give it an edge in memory-intensive tasks.

The NVIDIA GeForce MX550, a mobile GPU, achieves an average score of 33,209, which is 0.3% behind the A5000. Despite being a laptop part, the MX550's aggregate benchmark result is nearly identical to the A5000's. However, the A5000's 24 GB frame buffer and 768.0 GB/s bandwidth far exceed the MX550's typical specifications, making the A5000 better suited for professional workloads that demand large memory pools.

The NVIDIA GeForce RTX 3050 Mobile records an average score of 33,170, a 0.4% deficit relative to the A5000. This mobile RTX part comes close to matching the A5000's overall score, but the A5000's workstation pedigree—including 64 RT cores and 256 tensor cores—positions it for compute and ray tracing tasks that go beyond typical mobile gaming. The 0.4% gap is within the margin of error for benchmark variability.

The NVIDIA T550 Mobile, another professional mobile GPU, averages 33,161, also 0.4% behind the A5000. The T550 Mobile is a lower-tier workstation part, and the A5000's 0.4% lead reflects a slight performance advantage. Yet, the A5000's dual-slot design and 230 W TDP contrast with the T550's mobile form factor, underscoring the A5000's role in desktop workstations where power and cooling are less constrained.

Ray Tracing and Feature Set

The RTX A5000 includes 64 dedicated ray tracing cores and 256 tensor cores, enabling hardware-accelerated ray tracing and AI-based features. These cores support the DirectX 12 Ultimate API (12_2), which includes features like variable rate shading and mesh shaders. The card also supports OpenGL 4.6 and Vulkan 1.4, ensuring broad API compatibility across professional and creative applications.

The GPU's compute capabilities are substantial: it delivers 27.77 TFLOPS of FP32 and the same 27.77 TFLOPS for FP16, with a 1:1 ratio. The pixel fill rate is 162.7 GPixel/s, and the texture fill rate is 433.9 GTexel/s. These figures indicate strong throughput for geometry and pixel-heavy workloads. The memory subsystem, with 24 GB of GDDR6 and 768.0 GB/s bandwidth, provides ample capacity and speed for large textures, complex scenes, and data-parallel tasks.

The card features 4x DisplayPort 1.4a outputs, supporting multiple high-resolution displays. It uses a PCIe 4.0 x16 bus interface, ensuring high bandwidth to the host system. The power requirement is a single 8-pin connector, with a suggested PSU of 550 W. The A5000 is a dual-slot card, measuring 267 mm in length and 112 mm in height.

Who Should Consider It

The RTX A5000 is aimed at professionals who require a large memory buffer and high compute throughput. The 24 GB GDDR6 memory and 768.0 GB/s bandwidth are particularly suited for applications that handle massive datasets, such as 3D rendering, scientific simulation, and machine learning inference. The FP32 performance of 27.77 TFLOPS and the presence of tensor cores make it a capable choice for compute-heavy workflows, while the 64 RT cores enable hardware-accelerated ray tracing in supported applications.

Given its 77th percentile ranking, the A5000 outperforms the majority of GPUs in the database, making it a strong performer for its generation. The card's dual-slot design and 230 W TDP fit into standard workstation chassis with adequate power supplies. The production status is end-of-life, so it may be a legacy option, but its performance remains relevant for many professional tasks. Users who need reliable, high-end workstation graphics without the constraints of mobile hardware will find the A5000 a suitable candidate.

Benchmark Performance

The A5000's average benchmark score of 33,294 is 0.1% higher than the AMD Radeon Pro 570's 33,258, 0.3% higher than the GeForce MX550's 33,209, and 0.4% higher than both the GeForce RTX 3050 Mobile's 33,170 and the T550 Mobile's 33,161. These deltas are tiny, indicating that in aggregate, the A5000 is effectively performance-equivalent to these rivals. However, the A5000's individual benchmark scores reveal specific strengths.

In the 3DMark Steel Nomad DX12 test, the A5000 scores 3,783. This is a modern DirectX 12 workload, and the score reflects the card's ability to handle contemporary graphics features. The Geekbench OpenCL score of 155,247 and Vulkan score of 137,199 demonstrate strong general compute performance across different APIs. These results suggest that the A5000 can accelerate a wide range of compute tasks, from physics simulations to image processing.

The Passmark suite provides additional granularity. The DirectX 10 score is 153, DirectX 11 is 187, DirectX 12 is 87, and DirectX 9 is 251. Notably, the DirectX 9 score is higher than the DirectX 12 score, indicating that the card performs relatively better on legacy APIs in this particular test. The Passmark G2D score of 1,032 covers 2D operations, while the G3D score of 22,541 reflects overall 3D performance. The GPU compute score of 12,455 further quantifies compute throughput.

The A5000's FP32 and FP16 throughput of 27.77 TFLOPS each, combined with a pixel rate of 162.7 GPixel/s and a texture rate of 433.9 GTexel/s, underline its raw processing power. The 24 GB memory capacity and 768.0 GB/s bandwidth ensure that data-intensive workloads are not bottlenecked by memory limitations. The 77th percentile ranking confirms that the A5000 sits above the majority of GPUs in the database, even though its nearest rivals in average score are within 0.4%—a signal of the density of performance around this level.
