AMD Radeon Pro WX 8200 vs NVIDIA RTX A5500 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the NVIDIA RTX A5500 Mobile and the AMD Radeon Pro WX 8200 in the two shared benchmark tests. In Geekbench OpenCL, the NVIDIA part scores 124287 against 69774 for the AMD card, a delta of 78.1% in favor of the RTX A5500 Mobile. That is not a marginal edge; it is a nearly eight-tenths improvement in raw compute throughput as measured by the OpenCL workload.

The Vulkan result tells a similar story, though the margin narrows slightly in percentage terms. The RTX A5500 Mobile records 103601, while the Radeon Pro WX 8200 manages 69076. The delta here is 50%, still a substantial lead for the NVIDIA product. Across both benchmarks, the NVIDIA RTX A5500 Mobile wins 2 tests, and the AMD Radeon Pro WX 8200 wins 0.

Looking at the broader database context, the NVIDIA RTX A5500 Mobile sits at the 94th percentile among all GPUs, with an average benchmark score of 113944. Its nearest rivals include the NVIDIA Tesla V100 SXM2 16 GB at 114395, which is 0.4% ahead, and the NVIDIA RTX 4000 SFF Ada Generation at 117088, which is 2.7% ahead. The AMD Radeon PRO W7900 trails it by 2.9% with a score of 110725, and the NVIDIA GB10 is 2.9% ahead at 117393. This places the RTX A5500 Mobile in a competitive band where it is within roughly 3% of several high-end workstation and data center parts.

The AMD Radeon Pro WX 8200, by contrast, holds the 90th percentile with an average benchmark score of 69870. Its nearest rivals are clustered tightly around it: the NVIDIA Quadro P6000 at 69986 is 0.2% ahead, the NVIDIA RTX A3000 Mobile at 70140 is 0.4% ahead, the NVIDIA CMP 90HX at 69000 is 1.3% behind, and the AMD Radeon RX 6600 LE at 70829 is 1.4% ahead. The AMD card is therefore competitive with its immediate peers, but the gap to the RTX A5500 Mobile is enormous, roughly 63% in average benchmark score.

What stands out in the head-to-head data is that the NVIDIA part wins both tests by wide margins, and the OpenCL delta of 78.1% is larger than the Vulkan delta of 50%. This suggests the NVIDIA architecture benefits more from the OpenCL compute path, while the Vulkan result, though still a clear win, sees the AMD card close some of the relative distance. Even so, the absolute scores leave no ambiguity about which GPU delivers higher measured performance.

Architecture Differences

The two GPUs come from fundamentally different design generations and process nodes. The NVIDIA RTX A5500 Mobile uses the GA103 chip built on Ampere architecture, manufactured by Samsung on an 8 nm process. It integrates 22,000 million transistors on a die size of 496 mm², yielding a transistor density of 44.4M per mm². The AMD Radeon Pro WX 8200 uses the Vega 10 chip with GCN 5.0 architecture, built by GlobalFoundries on a 14 nm process. It packs 12,500 million transistors into a 495 mm² die, for a density of 25.3M per mm². The die sizes are nearly identical, but NVIDIA fits nearly twice the transistor count into roughly the same area thanks to the denser 8 nm node.

The compute resources differ sharply. The RTX A5500 Mobile has 7424 shading units, 232 TMUs, 96 ROPs, 58 RT cores, and 232 tensor cores. The Radeon Pro WX 8200 has 3584 shading units, 224 TMUs, and 64 ROPs, with no RT cores and no tensor cores listed. The NVIDIA part more than doubles the shading unit count and adds dedicated ray tracing and tensor hardware, which the AMD card lacks entirely. This explains much of the benchmark gap, as the RTX A5500 Mobile can offload ray tracing and AI workloads to specialized hardware.

Clock behavior shows both cards boost to 1500 MHz, but the base clocks differ. The NVIDIA part runs at 975 MHz base, while the AMD part has a 1200 MHz base clock. The AMD card starts higher but has no additional headroom beyond the shared 1500 MHz boost. The NVIDIA card has a longer climb from base to boost, which may indicate a more aggressive power management curve.

Memory configurations are strikingly different in type and bus width but identical in bandwidth. The RTX A5500 Mobile uses 16 GB of GDDR6 on a 256 bit bus, with memory clocked at 2000 MHz or 16 Gbps effective, delivering 512.0 GB/s. The Radeon Pro WX 8200 uses 8 GB of HBM2 on a 2048 bit bus, with memory at 1000 MHz or 2 Gbps effective, also delivering 512.0 GB/s. Equal bandwidth, but the NVIDIA card has twice the capacity. The AMD card's HBM2 provides a very wide but slower-clocked interface, while the NVIDIA card relies on a narrower GDDR6 bus running at much higher effective speed.

The power profiles also diverge. The RTX A5500 Mobile is rated at 165 W TDP, while the Radeon Pro WX 8200 draws 230 W. The AMD card requires a dual-slot cooler, a 6-pin plus 8-pin power connector setup, and a suggested 550 W power supply. The NVIDIA mobile part has no power connectors listed, consistent with a notebook-oriented design.

Both cards are end-of-life products. The NVIDIA RTX A5500 Mobile was released in March 2022, while the AMD Radeon Pro WX 8200 came out in August 2018. The NVIDIA card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The NVIDIA part has the newer API feature set, including the higher DirectX version and the more recent Vulkan revision.

The Verdict

The benchmark data points to one clear conclusion: the NVIDIA RTX A5500 Mobile is the faster GPU by a wide margin. It wins both shared tests, posts an average score of 113944 against 69870, and sits at the 94th percentile compared to the AMD card's 90th. The OpenCL delta of 78.1% and the Vulkan delta of 50% are both decisive. Anyone choosing between these two strictly on measured performance should select the NVIDIA part.

The architecture comparison reinforces the benchmark results. The RTX A5500 Mobile has more than double the shading units, adds RT and tensor cores, uses a denser 8 nm process, and carries twice the memory capacity. The AMD card counters with a higher base clock, a wider 2048 bit HBM2 bus, and a lower TDP relative to its performance class, but its 230 W draw is higher in absolute terms than the NVIDIA part's 165 W.

There is a caveat in the data for system builders. The AMD card is a dual-slot desktop workstation card with fixed dimensions, 4x mini-DisplayPort outputs, and a 6-pin plus 8-pin power requirement. The NVIDIA part is a mobile GPU with no power connectors and display output dependent on the portable device. These are different physical form factors, so the choice is not purely about performance but also about the target system type.

Where Each One Wins

The NVIDIA RTX A5500 Mobile wins in every measured benchmark category. It wins OpenCL with 124287 versus 69774, and it wins Vulkan with 103601 versus 69076. It wins on raw compute metrics: FP32 of 22.27 TFLOPS versus 10.75 TFLOPS, pixel rate of 144.0 GPixel/s versus 96.00 GPixel/s, and texture rate of 348.0 GTexel/s versus 336.0 GTexel/s. It wins on memory capacity with 16 GB versus 8 GB, and it wins on feature support with DirectX 12 Ultimate, Vulkan 1.4, and dedicated RT and tensor cores.

The AMD Radeon Pro WX 8200 wins in a few specific specification areas. It has a higher base clock at 1200 MHz versus 975 MHz. It has a much wider memory bus at 2048 bit versus 256 bit. It offers a specific desktop form factor with four mini-DisplayPort 1.4a outputs and a defined 267 mm length, which matters for fixed workstation chassis. It also has a higher FP16 rate of 21.50 TFLOPS versus 22.27 TFLOPS on the NVIDIA card, though this is a narrow 0.77 TFLOPS margin and the NVIDIA card achieves FP16 at a 1:1 ratio while the AMD card uses a 2:1 ratio.

For use cases, the data suggests the NVIDIA RTX A5500 Mobile is the choice for compute-heavy workloads, ray tracing, and AI-adjacent tasks, given its RT cores, tensor cores, and 22.27 TFLOPS FP32. The AMD Radeon Pro WX 8200 remains viable for legacy desktop workstation setups that need a dual-slot card with direct DisplayPort outputs and a wide memory interface, but the benchmark record shows it cannot match the NVIDIA part in raw performance. The 999 USD launch MSRP for the AMD card is noted once, but the recorded performance data places it in a lower tier regardless of price considerations.
