GPU Comparison

The Verdict

The data presents a clear hierarchy. The NVIDIA RTX A2000 outperforms the AMD Radeon Pro 5500 XT in every direct benchmark comparison available, and its average benchmark score of 46043 sits slightly above the AMD card's 45384. The RTX A2000 wins 2 head-to-head tests, while the Radeon Pro 5500 XT wins none. For users prioritizing raw compute performance across OpenCL and Vulkan workloads, the RTX A2000 is the statistically superior choice.

However, the Radeon Pro 5500 XT is not without its own advantages. It offers 8 GB of memory versus the RTX A2000's 6 GB, and it delivers higher FP16 throughput at 10.80 TFLOPS compared to 7.987 TFLOPS. The AMD card also boosts to a higher clock speed (1757 MHz vs 1200 MHz) and consumes more power (125 W vs 70 W), suggesting it may sustain heavier sustained loads. Users who prioritize memory capacity or FP16 compute for specific scientific or AI workloads may find the AMD card more suitable.

The RTX A2000 also holds a percentile advantage: it ranks in the 85th percentile of all GPUs, while the Radeon Pro 5500 XT ranks in the 84th. This is a marginal difference, but it reflects the NVIDIA card's slightly higher average score. The verdict, strictly from the data, is that the RTX A2000 is the stronger performer in most compute scenarios, while the Radeon Pro 5500 XT offers a memory capacity and FP16 compute advantage for specialized tasks.

Architecture Differences

The two cards are built on fundamentally different architectures. The NVIDIA RTX A2000 uses the GA106 chip based on Ampere architecture, manufactured on an 8 nm process by Samsung. It integrates 12,000 million transistors on a 276 mm² die, yielding a transistor density of 43.5M per mm². In contrast, the AMD Radeon Pro 5500 XT uses the Navi 14 chip based on RDNA 1.0 architecture, manufactured on a 7 nm process by TSMC. It packs 6,400 million transistors on a 158 mm² die, with a density of 40.5M per mm².

The RTX A2000 features 3328 shading units, 104 texture mapping units, and 48 raster output pipelines. It also includes 26 ray tracing cores and 104 tensor cores, which the AMD card lacks entirely, the Radeon Pro 5500 XT's specification lists no RT cores and no tensor cores. This reflects a fundamental design divergence: the NVIDIA card is built for ray-traced and AI-accelerated workloads, while the AMD card focuses on traditional rasterization.

Memory architectures also differ substantially. The RTX A2000 uses a 192-bit memory bus with 6 GB of GDDR6 memory, delivering 288.0 GB/s of bandwidth. The Radeon Pro 5500 XT uses a narrower 128-bit bus but compensates with 8 GB of GDDR6 memory, achieving 224.0 GB/s. The NVIDIA card's wider bus gives it a 28.6% bandwidth advantage (288.0 vs 224.0 GB/s), which likely contributes to its benchmark superiority.

Clock behavior further distinguishes the two. The RTX A2000 has a base clock of 562 MHz and a boost clock of 1200 MHz, while the Radeon Pro 5500 XT runs at 1187 MHz base and 1757 MHz boost. The AMD card's clocks are significantly higher, yet the NVIDIA card still wins in compute benchmarks, indicating architectural efficiency advantages.

The RTX A2000 supports DirectX 12 Ultimate (12_2), while the Radeon Pro 5500 XT is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The NVIDIA card also provides 4x mini-DisplayPort 1.4a outputs, whereas the AMD card has no display outputs, positioning it as an integrated graphics processor (IGP) for Mac systems. The RTX A2000 uses PCIe 4.0 x16, while the AMD card uses PCIe 4.0 x8.

Head-to-Head Benchmarks

The direct benchmark comparison includes two tests, both of which the NVIDIA RTX A2000 wins decisively. In Geekbench OpenCL, the RTX A2000 scores 67695 against the Radeon Pro 5500 XT's 41772, a delta of 62.1%. This is a massive margin that reflects the NVIDIA card's higher shading unit count (3328 vs 1536) and wider memory bus (192-bit vs 128-bit).

In Geekbench Vulkan, the gap widens further. The RTX A2000 scores 69089, while the Radeon Pro 5500 XT scores 39601, a delta of 74.5%. This nearly three-quarters performance advantage suggests that the NVIDIA card's architecture handles Vulkan's compute and graphics workloads with significantly greater efficiency. The RTX A2000's tensor cores and RT cores may contribute to this advantage, though the benchmark itself does not specify which features are exercised.

The RTX A2000 also holds the edge in the aggregate metric. Its average benchmark score of 46043 is 1.5% higher than the Radeon Pro 5500 XT's 45384. Both cards sit near each other in the overall GPU hierarchy: the RTX A2000's nearest rivals include the NVIDIA RTX 5880 Ada Generation (0.2% higher score) and the Intel Arc A730M (1% higher), while the Radeon Pro 5500 XT's nearest rivals include the Intel Arc A730M (0.5% higher) and the NVIDIA GeForce RTX 5090 Mobile (0.5% lower).

Neither card has a benchmark win in the other's favor. The head-to-head table shows winsA: 2 and winsB: 0, meaning the RTX A2000 is the consistent winner across all tested workloads. The AMD card's higher boost clock (1757 MHz vs 1200 MHz) and higher texture rate (168.7 GTexel/s vs 124.8 GTexel/s) do not translate into benchmark victories, indicating that raw clock speed and texture throughput are insufficient to overcome the NVIDIA card's architectural advantages.

Where Each One Wins

The NVIDIA RTX A2000 wins in compute-heavy applications that leverage OpenCL and Vulkan. Its 62.1% OpenCL advantage and 74.5% Vulkan advantage make it the clear choice for general-purpose GPU compute, scientific simulations, and rendering workloads that use these APIs. The card's 26 RT cores and 104 tensor cores provide dedicated hardware for ray tracing and AI acceleration, features entirely absent from the Radeon Pro 5500 XT. Its 288.0 GB/s memory bandwidth, enabled by the 192-bit bus, supports data-intensive tasks more effectively than the AMD card's 224.0 GB/s. For users requiring display outputs, the RTX A2000's 4x mini-DisplayPort 1.4a connections allow direct monitor attachment, while the Radeon Pro 5500 XT has none.

The AMD Radeon Pro 5500 XT wins in specific scenarios that favor its unique specifications. Its 8 GB memory capacity exceeds the RTX A2000's 6 GB, making it better suited for workloads that require larger datasets or higher-resolution textures that exceed 6 GB. Its FP16 throughput of 10.80 TFLOPS is 35.2% higher than the RTX A2000's 7.987 TFLOPS, which benefits applications that use half-precision arithmetic, such as certain machine learning inference tasks or image processing pipelines. The higher boost clock of 1757 MHz may also provide better performance in latency-sensitive, low-occupancy workloads where clock speed matters more than parallel throughput. However, these advantages are not reflected in the available benchmarks, which show the RTX A2000 winning all tests. The Radeon Pro 5500 XT's classification as an IGP with no display outputs suggests it is designed for integration into Mac systems, where the host platform handles display output. Its 7 nm process and smaller die (158 mm² vs 276 mm²) may offer manufacturing efficiency benefits, but these do not surface in performance metrics. The FP16 advantage at 2:1 ratio versus the NVIDIA card's 1:1 ratio indicates that AMD's architecture is optimized for specific half-precision workloads, making it a niche choice for users who prioritize that capability over all other factors.
