AMD Radeon Pro 555X vs AMD Radeon Pro WX 3200 Comparison

Head-to-Head Benchmarks

The database contains only one directly comparable benchmark run between these two mobile and workstation graphics processors: Geekbench OpenCL. In that test, the AMD Radeon Pro 555X records a score of 12,628, while the AMD Radeon Pro WX 3200 records 11,228. The resulting delta is 12.5% in favor of the Radeon Pro 555X, giving it a clean 1 to 0 win tally in head-to-head comparisons.

That 12.5% margin is substantial in the context of their peer groups. The Radeon Pro 555X sits at the 54th percentile among all GPUs in the database, with an average benchmark score of 13,321 across all recorded tests. Its nearest rivals cluster tightly around that figure: the NVIDIA GeForce GTX 480 trails by only 0.2%, the AMD FirePro M6100 leads by 0.2%, the AMD Radeon RX 5500M leads by 0.3%, and the AMD Radeon HD 8950M leads by 0.4%. The Radeon Pro 555X is therefore essentially level with a broad group of mid-range parts from several generations.

The Radeon Pro WX 3200, by contrast, sits at the 50th percentile, with an average benchmark score of 11,228 from its single recorded OpenCL result. Its nearest rivals include the AMD FirePro W4300 at a 0% delta, the NVIDIA GeForce GTX 780M trailing by 0.3%, and two NVIDIA RTX PRO 6000 Blackwell Max-Q variants each leading by 1.3%. The WX 3200 is positioned slightly lower in the overall performance distribution, and the recorded data confirms that the Radeon Pro 555X holds a clear advantage in raw compute throughput as measured by OpenCL.

The magnitude of the win matters. A 12.5% lead in a synthetic compute workload typically translates into measurable differences in GPU-bound tasks that scale well across shading units. Given that neither part supports ray tracing cores or tensor cores, OpenCL performance is one of the primary quantitative indicators available for comparing their compute capabilities. The data shows a decisive, if not overwhelming, edge for the Radeon Pro 555X.

Architecture Differences

Both GPUs share the same fundamental architecture generation: GCN 4.0. Both are fabricated on a 14 nm process at GlobalFoundries. Both support DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. Both use 4 GB of GDDR5 memory on a 128 bit bus. The similarities end there.

The Radeon Pro 555X uses the Polaris 21 chip, which contains 3,000 million transistors on a 123 mm² die, yielding a transistor density of 24.4 million per square millimeter. The Radeon Pro WX 3200 uses the smaller Polaris 23 chip, with 2,200 million transistors on a 103 mm² die, for a transistor density of 21.4 million per square millimeter. The 555X therefore packs roughly 36% more transistors into a die that is only about 19% larger, which explains part of its performance advantage.

The compute configuration differs significantly. The Radeon Pro 555X has 768 shading units, 48 texture mapping units, and 16 ROPs. The Radeon Pro WX 3200 has 640 shading units, 32 TMUs, and 16 ROPs. The 555X carries 20% more shaders and 50% more TMUs, while both parts have identical ROP counts. This configuration suggests the 555X should excel in texture-heavy workloads, while pixel fill rate remains a point of comparison.

The recorded pixel and texture rates reflect these architectural differences. The Radeon Pro 555X achieves 14.51 GPixel/s and 43.54 GTexel/s. The Radeon Pro WX 3200 achieves 20.72 GPixel/s and 41.44 GTexel/s. Despite the identical ROP count, the WX 3200 posts a significantly higher pixel rate; the data indicates the WX 3200 is about 43% ahead in pixel throughput. The texture rates are much closer, with the 555X ahead by roughly 5%. The FP32 compute figures tell a third story: the 555X delivers 1,393.2 GFLOPS, while the WX 3200 delivers 1.658 TFLOPS, meaning the WX 3200 is about 19% ahead in raw FP32 throughput. Both parts offer FP16 at a 1:1 ratio with FP32.

Memory clocks also differ. The 555X runs its GDDR5 at 1470 MHz with 5.9 Gbps effective, producing 94.08 GB/s of bandwidth. The WX 3200 runs at 1500 MHz with 6 Gbps effective, producing 96.00 GB/s. The WX 3200 has a slight bandwidth advantage of about 2%.

The two parts diverge sharply in physical design and power characteristics. The Radeon Pro 555X is an integrated GPU (IGP) with a 75 W TDP, no power connectors, and display outputs described as portable device dependent. It uses a PCIe 3.0 x8 bus interface. The Radeon Pro WX 3200 is a single-slot card with a 65 W TDP, no power connectors, a suggested PSU of 250 W, and four mini-DisplayPort 1.4a outputs. It measures 167 mm in length and 69 mm in height, and also uses PCIe 3.0 x8. The WX 3200 is the only one of the two with a launch MSRP, listed at 199 USD.

Where Each One Wins

The benchmark data gives the Radeon Pro 555X the win in the only directly comparable test, Geekbench OpenCL, by 12.5%. Its larger shader and TMU counts align with that result. The 555X should be the preferred choice for compute-oriented OpenCL workloads, texture-heavy rendering tasks, and any application that scales well with shading unit count.

The Radeon Pro WX 3200, despite losing the OpenCL head-to-head, holds advantages in several measured specifications. Its pixel rate of 20.72 GPixel/s is substantially higher than the 555X's 14.51 GPixel/s, which suggests an advantage in fill-rate-bound scenarios such as certain types of rasterization and pixel-heavy effects. Its FP32 throughput of 1.658 TFLOPS exceeds the 555X's 1,393.2 GFLOPS by roughly 19%, indicating an edge in pure compute workloads that are not captured by the single OpenCL benchmark result. Its memory bandwidth of 96.00 GB/s is also slightly higher than the 555X's 94.08 GB/s.

The WX 3200 also offers a more conventional workstation form factor. The 555X is an IGP with portable device dependent outputs, meaning its display connectivity depends entirely on the host laptop. The WX 3200 provides four dedicated mini-DisplayPort 1.4a outputs on a single-slot card, making it a drop-in discrete GPU solution. For users who require multiple external displays in a fixed workstation chassis, the WX 3200's physical design is a clear practical advantage.

The 555X, on the other hand, has a lower transistor density of 24.4M per mm² versus 21.4M per mm², a higher TDP of 75 W versus 65 W, and a larger die. It also has a higher average benchmark score of 13,321 versus 11,228, and a higher percentile rank of 54 versus 50.

The Verdict

The data points in different directions depending on the workload. If the priority is raw OpenCL compute performance as measured by the database, the AMD Radeon Pro 555X is the stronger part, winning the head-to-head by 12.5% and sitting at a higher overall percentile. Its larger shader count and TMU count support this result.

If the priority is fill rate, the AMD Radeon Pro WX 3200 is the stronger part. Its pixel rate of 20.72 GPixel/s is far ahead of the 555X's 14.51 GPixel/s. Its FP32 throughput of 1.658 TFLOPS also exceeds the 555X's 1,393.2 GFLOPS, and its memory bandwidth is slightly higher. The WX 3200 additionally comes in a standard single-slot form factor with four dedicated display outputs, making it easier to deploy in a conventional workstation.

The recorded data does not include a Geekbench Vulkan or Metal result for the WX 3200, so those comparisons cannot be made. The 555X has scores of 14,479 in Metal and 12,855 in Vulkan, but no matching WX 3200 numbers exist in the database.

The choice comes down to deployment context. For a portable device where the GPU is integrated and compute performance matters most, the Radeon Pro 555X is the better option based on the benchmark data. For a workstation requiring discrete display outputs, lower power draw at 65 W, and high pixel throughput, the Radeon Pro WX 3200 has clear specification-level advantages despite losing the single OpenCL comparison.
