AMD Radeon PRO W7800 vs AMD Radeon Pro WX 8200 Comparison

The AMD Radeon PRO W7800 and the AMD Radeon Pro WX 8200 represent two distinct eras of workstation graphics, separated by roughly five years of architectural evolution. The recorded data shows the W7800 delivering an average benchmark score of 164,894, placing it in the 97th percentile of all GPUs, while the WX 8200 achieves an average of 69,870, sitting in the 90th percentile. The head-to-head benchmark results are unequivocal: the W7800 wins both recorded tests, with a 121.2% advantage in Geekbench OpenCL and a 154% advantage in Geekbench Vulkan. This is not a close contest; it is a generational leap expressed in raw compute performance, memory capacity, and feature support.

The Verdict

The data presents a clear hierarchy. For any professional workload involving modern 3D rendering, real-time ray tracing, or large dataset manipulation, the AMD Radeon PRO W7800 is the definitive choice. Its 45.25 TFLOPS of FP32 performance dwarfs the WX 8200's 10.75 TFLOPS, and its 32 GB of GDDR6 memory with 576.0 GB/s of bandwidth provides four times the capacity and 12.5% more bandwidth than the older card's 8 GB HBM2 configuration. The W7800 also supports DirectX 12 Ultimate and Vulkan 1.4, whereas the WX 8200 is limited to DirectX 12 (12_1) and Vulkan 1.3. For users running contemporary CAD, simulation, or visualization suites that leverage these modern APIs, the W7800 is the only rational option.

The AMD Radeon Pro WX 8200, while end-of-life and drastically slower, still holds relevance in one narrow scenario. Its 8 GB of HBM2 memory, while small by modern standards, operates over a massive 2048-bit bus, yielding 512.0 GB/s of bandwidth. For legacy applications that were optimized for the GCN architecture and do not benefit from newer instruction sets, the WX 8200 remains functional. However, its 10.75 TFLOPS FP32 and 96.00 GPixel/s pixel rate are so far behind the W7800's 323.2 GPixel/s that any compute-heavy task will show a dramatic difference. The verdict is simple: the W7800 wins on every recorded metric, and the WX 8200 is only suitable for light, legacy workstation duties where its lower 230 W TDP and single 6-pin plus 8-pin power requirement are acceptable.

Architecture Differences

The two cards are built on fundamentally different architectures, which explains the massive performance disparity. The AMD Radeon PRO W7800 uses the Navi 31 chip based on RDNA 3.0 architecture, codenamed Plum Bonito. It is fabricated on a 5 nm process at TSMC, packing 57,700 million transistors onto a 529 mm² die. This yields a transistor density of 109.1 million transistors per square millimeter, a figure that reflects the advanced manufacturing node.

In contrast, the AMD Radeon Pro WX 8200 uses the Vega 10 chip based on GCN 5.0 architecture. It is built on a 14 nm process at GlobalFoundries, with 12,500 million transistors spread across a 495 mm² die. The transistor density here is just 25.3 million per square millimeter. This means the W7800 packs over four and a half times more transistors into a similar physical area, enabling far more complex compute units and specialized hardware.

The architectural generation also dictates feature support. The W7800's RDNA 3.0 architecture includes 70 ray tracing cores, which are absent from the WX 8200's GCN 5.0 design. The W7800 also supports DirectX 12 Ultimate, a feature set that includes ray tracing and mesh shaders, while the WX 8200 is limited to DirectX 12 (12_1). The W7800's Vulkan support extends to version 1.4, whereas the WX 8200 tops out at Vulkan 1.3. These differences are not minor; they determine whether modern software can use the hardware's full capabilities.

The memory subsystems also reflect divergent design philosophies. The W7800 uses 32 GB of GDDR6 on a 256-bit bus, achieving 576.0 GB/s. The WX 8200 uses 8 GB of HBM2 on a 2048-bit bus, achieving 512.0 GB/s. The WX 8200's memory is physically closer to the compute die, but the W7800's higher clocked GDDR6 ultimately wins on bandwidth. The W7800 also has a much larger memory pool, which is critical for large 3D scenes, deep learning models, or high-resolution textures.

Specification Differences

The specification sheets reveal the scale of the generational gap. The W7800 has 4,480 shading units, 280 texture mapping units, and 128 raster output units. The WX 8200 has 3,584 shading units, 224 TMUs, and 64 ROPs. The W7800's pixel rate is 323.2 GPixel/s, more than triple the WX 8200's 96.00 GPixel/s. Texture rate follows suit: 707.0 GTexel/s for the W7800 versus 336.0 GTexel/s for the WX 8200.

Compute throughput is where the difference becomes stark. The W7800 delivers 45.25 TFLOPS of FP32 performance and 90.50 TFLOPS of FP16 (2:1 ratio). The WX 8200 delivers 10.75 TFLOPS FP32 and 21.50 TFLOPS FP16. This is a 4.2x difference in raw floating-point capability. Clock speeds also differ: the W7800 has a base clock of 1895 MHz and a boost clock of 2525 MHz, while the WX 8200 runs at 1200 MHz base and 1500 MHz boost. The memory clock is 2250 MHz (18 Gbps effective) on the W7800 versus 1000 MHz (2 Gbps effective) on the WX 8200.

Power and connectivity also diverge. The W7800 has a TDP of 260 W and requires 2x 8-pin power connectors with a 600 W suggested PSU. The WX 8200 has a TDP of 230 W, uses 1x 6-pin plus 1x 8-pin, and suggests a 550 W PSU. The W7800 uses PCIe 4.0 x16, while the WX 8200 uses PCIe 3.0 x16. Display outputs favor the newer card: the W7800 offers 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1, whereas the WX 8200 offers 4x mini-DisplayPort 1.4a. Physical dimensions are close: the W7800 is 280 mm long, 110 mm tall, and 40 mm wide; the WX 8200 is 267 mm long and 111 mm tall with no recorded width.

Head-to-Head Benchmarks

The database records two head-to-head benchmark tests, and the AMD Radeon PRO W7800 wins both by enormous margins. In Geekbench OpenCL, the W7800 scores 154,366 against the WX 8200's 69,774, a delta of 121.2%. This means the W7800 is roughly 2.2 times faster in general-purpose compute tasks. For a workstation user, this translates directly to faster rendering times, quicker simulation solves, and more responsive viewport performance in applications that offload work to the GPU.

In Geekbench Vulkan, the gap widens further. The W7800 scores 175,422, while the WX 8200 manages 69,076, a delta of 154%. This near-2.5x advantage in Vulkan workloads is particularly notable because Vulkan is a low-overhead API that leverages the hardware's raw capabilities. The W7800's architecture is clearly better suited to modern graphics pipelines, which rely heavily on parallel compute and explicit command submission.

The average benchmark scores also reinforce this narrative. The W7800's average of 164,894 places it within 1.5% of the NVIDIA A100 PCIe 40 GB and within 2.2% of the AMD Radeon Pro W6900X. The WX 8200's average of 69,870 sits within 1.3% of the NVIDIA CMP 90HX and within 1.4% of the AMD Radeon RX 6600 LE. These rival comparisons show that the W7800 competes with top-tier accelerators, while the WX 8200 is firmly in the mid-range of the 90th percentile.

Where Each One Wins

The AMD Radeon PRO W7800 wins in every scenario captured by the database. For compute-heavy workloads such as 3D rendering, machine learning inference, or scientific simulations, the W7800's 45.25 TFLOPS FP32 and 90.50 TFLOPS FP16 provide the headroom needed for large datasets. Its 32 GB memory capacity allows loading entire scenes or models without spilling to system memory, a critical advantage for professionals working on complex visual effects or architectural visualizations. The 70 ray tracing cores make it suitable for real-time ray-traced previews in modern DCC tools, a feature the WX 8200 cannot offer.

The W7800 also wins on connectivity and future-proofing. Its DisplayPort 2.1 outputs support higher resolutions and refresh rates than the WX 8200's DisplayPort 1.4a. The PCIe 4.0 interface doubles the theoretical bandwidth to the host system compared to PCIe 3.0, which benefits workflows that frequently transfer geometry or texture data between CPU and GPU. The W7800's active production status ensures ongoing driver support and availability.

The AMD Radeon Pro WX 8200's only conceivable wins are in legacy scenarios. Its GCN 5.0 architecture may be better understood by older software that was written before RDNA's compute unit layout. Its lower TDP of 230 W and single 6-pin plus 8-pin power requirement could be easier to accommodate in older workstations with limited power delivery. The WX 8200 also has four mini-DisplayPort 1.4a outputs, which may suit a specific multi-display setup that predates DisplayPort 2.1 adoption. However, the recorded data shows zero benchmark wins for the WX 8200, and its 8 GB memory capacity is a hard ceiling for modern datasets. Professionals should treat the WX 8200 as a fallback for legacy software, not a primary tool.
