AMD Radeon Pro WX 8200 vs NVIDIA RTX A4500 Mobile Comparison

The NVIDIA RTX A4500 Mobile and AMD Radeon Pro WX 8200 are both end-of-life workstation GPUs, but they represent vastly different design philosophies and performance tiers. The data shows a clear overall winner in the NVIDIA part, which posts an average benchmark score of 91,134 against the AMD's 69,870. This places the RTX A4500 Mobile in the 93rd percentile of all GPUs, while the Radeon Pro WX 8200 sits in the 90th percentile. However, the comparison is not entirely one-sided, as the AMD card offers distinct architectural advantages in specific workloads.

Head-to-Head Benchmarks

The most decisive victory for the NVIDIA RTX A4500 Mobile comes in the Geekbench OpenCL test. Here, the NVIDIA card scores 105,307, absolutely dwarfing the AMD Radeon Pro WX 8200's 69,774. This represents a massive 50.9% performance advantage for the RTX A4500 Mobile, making it the single largest gap between the two cards in any benchmark. This result is particularly striking given that both cards offer identical memory bandwidth of 512.0 GB/s, suggesting that the NVIDIA architecture is far more efficient at extracting compute performance from its memory subsystem.

The margin narrows considerably in the Geekbench Vulkan test, though the NVIDIA card still emerges victorious. The RTX A4500 Mobile scores 76,960, while the Radeon Pro WX 8200 manages 69,076. This 11.4% delta is more modest but still represents a solid win for the NVIDIA part. The Vulkan result indicates that the AMD card is comparatively stronger in this API, likely due to its higher texture rate, but it still cannot overcome the NVIDIA card's raw compute advantage.

Overall, the RTX A4500 Mobile wins both head-to-head benchmark comparisons, securing 2 wins against 0 for the Radeon Pro WX 8200. The data suggests that the NVIDIA card is the superior choice for compute-heavy tasks, particularly those leveraging OpenCL, where it nearly doubles the performance of its AMD rival. The Vulkan gap, while smaller, still firmly favors the NVIDIA part.

Architecture Differences

The two cards are built on fundamentally different architectures and process nodes. The NVIDIA RTX A4500 Mobile uses the GA104 chip based on the Ampere architecture, manufactured on an 8 nm process at Samsung. This modern node packs 17,400 million transistors into a 392 mm² die, achieving a transistor density of 44.4M per mm². In contrast, the AMD Radeon Pro WX 8200 relies on the much older Vega 10 chip using GCN 5.0 architecture, built on a 14 nm process at GlobalFoundries. This older node houses 12,500 million transistors across a larger 495 mm² die, resulting in a significantly lower transistor density of just 25.3M per mm².

These architectural differences manifest in starkly different compute configurations. The NVIDIA card features 5,888 shading units, 184 texture mapping units, and 96 raster output pipelines. It also includes 46 dedicated ray tracing cores and 184 tensor cores, reflecting its modern Ampere design. The AMD card, by contrast, offers only 3,584 shading units but compensates with 224 texture mapping units and 64 ROPs. Crucially, the Radeon Pro WX 8200 lacks dedicated ray tracing and tensor cores entirely, which severely limits its feature set for modern workloads.

Memory technology also diverges sharply. The RTX A4500 Mobile uses 16 GB of GDDR6 memory on a 256-bit bus, while the Radeon Pro WX 8200 uses just 8 GB of HBM2 memory on a massive 2048-bit bus. Both achieve the same 512.0 GB/s bandwidth, but the NVIDIA card does so with far fewer pins and lower power consumption. The clock speeds tell a similar story: both cards boost to 1500 MHz, but the NVIDIA card runs at a base clock of 930 MHz versus the AMD's 1200 MHz, indicating the AMD design relies on higher sustained clocks to compensate for its older architecture.

Where Each One Wins

The NVIDIA RTX A4500 Mobile is the clear winner in raw compute performance. Its FP32 throughput of 17.66 TFLOPS is 64% higher than the AMD card's 10.75 TFLOPS, making it the superior choice for single-precision compute tasks. The NVIDIA card also excels in pixel processing, delivering 144.0 GPixel/s against the AMD's 96.00 GPixel/s, a 50% advantage that benefits rasterization-heavy workloads. Additionally, the RTX A4500 Mobile offers 512 GB/s bandwidth with 16 GB of memory, providing double the capacity of the AMD card at identical bandwidth, which is critical for large datasets.

The AMD Radeon Pro WX 8200, while losing on most fronts, has specific strengths. Its FP16 throughput of 21.50 TFLOPS (2:1 ratio) actually exceeds the NVIDIA card's 17.66 TFLOPS (1:1 ratio), making it the better choice for workloads that can leverage half-precision arithmetic. The AMD card also boasts a higher texture rate of 336.0 GTexel/s versus the NVIDIA's 276.0 GTexel/s, giving it an edge in texture-heavy rendering scenarios. Furthermore, the Radeon Pro WX 8200's dual-slot design with 4x mini-DisplayPort 1.4a outputs offers more flexible multi-display configurations compared to the NVIDIA card's portable-device-dependent outputs.

The power envelope is another differentiator. The RTX A4500 Mobile draws just 140 W and requires no power connectors, making it suitable for mobile workstations. The Radeon Pro WX 8200, however, demands a substantial 230 W and requires both a 6-pin and 8-pin power connector, along with a suggested 550 W power supply.
