AMD Radeon Pro WX 8200 vs AMD Radeon RX 7900M Comparison

The AMD Radeon RX 7900M and the AMD Radeon Pro WX 8200 represent two very different eras of AMD graphics hardware. The RX 7900M is a modern mobile solution built for the Radeon RX 7000 series, while the Pro WX 8200 is an older workstation card from the Radeon Pro Polaris generation. The recorded data shows a clear performance gap, but the story is more nuanced than simple speed. This analysis explores where each card excels, the architectural chasm between them, and what the benchmarks reveal about their respective strengths.

Where Each One Wins

The benchmark data points to a decisive overall victory for the RX 7900M. Across the two head-to-head tests recorded, the RX 7900M wins both, giving it a 2-0 record. The Pro WX 8200 does not secure a single win in these comparisons. However, the Pro WX 8200 holds its own in a different metric: it has a wider memory bus and a distinct memory type, which suggests specialized workloads might favor it, even if raw compute scores do not.

Looking at the average benchmark scores, the RX 7900M sits at 97,487, while the Pro WX 8200 trails at 69,870. That is a substantial gap, roughly 39.5% difference in favor of the newer card. The RX 7900M also ranks in the 94th percentile among all GPUs, while the Pro WX 8200 lands in the 90th percentile. This means the RX 7900M is not just faster than the Pro WX 8200; it is also closer to the top of the overall GPU hierarchy. The Pro WX 8200, despite its age, still performs respectably, but it is clearly outclassed by the newer architecture.

In terms of individual tests, the RX 7900M wins decisively in both OpenCL and Vulkan workloads. The Pro WX 8200 has a Metal benchmark score of 70,759, which is not directly compared head-to-head, but that figure is lower than the RX 7900M’s OpenCL and Vulkan scores. The data suggests the RX 7900M is the better choice for compute-heavy tasks, while the Pro WX 8200 might still find a niche in legacy software or specific workstation environments that rely on its older feature set.

Architecture Differences

The architectural divide between these two cards is vast. The RX 7900M uses the Navi 31 chip built on the RDNA 3.0 architecture, fabricated on a 5 nm process at TSMC. It packs 57,700 million transistors into a 529 mm² die, giving a transistor density of 109.1 million per square millimeter. In contrast, the Pro WX 8200 uses the Vega 10 chip based on the older GCN 5.0 architecture, manufactured on a 14 nm process at GlobalFoundries. That chip contains only 12,500 million transistors on a 495 mm² die, resulting in a density of 25.3 million per square millimeter. The RX 7900M has over four times the transistor count in a slightly larger package, which explains much of its performance advantage.

The memory subsystems are also fundamentally different. The RX 7900M uses 16 GB of GDDR6 memory on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The Pro WX 8200 uses 8 GB of HBM2 memory on a massive 2048-bit bus, yielding 512.0 GB/s of bandwidth. While the RX 7900M has more capacity and slightly higher bandwidth, the Pro WX 8200’s HBM2 architecture offers a different latency profile and power characteristic. The RX 7900M’s memory clock is listed at 2250 MHz with 18 Gbps effective, while the Pro WX 8200 runs at 1000 MHz with 2 Gbps effective. The newer card’s memory is far faster in raw clock terms, but the older card’s wider bus compensates somewhat.

Compute resources differ sharply. The RX 7900M has 4,608 shading units, 288 texture mapping units, and 192 raster output units. It also includes 72 ray tracing cores, a feature entirely absent from the Pro WX 8200. The Pro WX 8200, by contrast, has 3,584 shading units, 224 TMUs, and only 64 ROPs. The pixel rate for the RX 7900M is 401.3 GPixel/s, compared to 96.00 GPixel/s for the Pro WX 8200. Texture rates are 601.9 GTexel/s versus 336.0 GTexel/s. The FP32 performance is 38.52 TFLOPS for the RX 7900M versus 10.75 TFLOPS for the Pro WX 8200. These numbers show the RX 7900M is not just incrementally faster; it is multiple times faster in nearly every compute metric.

Power and physical design also separate the two. The RX 7900M has a TDP of 180 W and is an IGP (integrated graphics processor) with no power connectors, designed for portable devices. The Pro WX 8200 has a TDP of 230 W, is a dual-slot card, and requires a 1x 6-pin plus 1x 8-pin power connector, with a suggested PSU of 550 W. The Pro WX 8200 is a full-length card at 267 mm, while the RX 7900M’s dimensions are not recorded because it is portable-device dependent.

Specification Differences

The key specification differences between the two cards are stark and numerous. The RX 7900M uses a 5 nm process, while the Pro WX 8200 uses 14 nm. Transistor counts differ dramatically: 57,700 million versus 12,500 million. Die size is similar (529 mm² versus 495 mm²), but transistor density is vastly higher on the newer card. Base clocks are 1825 MHz for the RX 7900M versus 1200 MHz for the Pro WX 8200. Boost clocks are 2090 MHz versus 1500 MHz. Memory size is 16 GB versus 8 GB, with different types (GDDR6 versus HBM2) and bus widths (256-bit versus 2048-bit). Shading units, TMUs, and ROPs are all higher on the RX 7900M. The RX 7900M has ray tracing cores, while the Pro WX 8200 has none. TDP is lower on the RX 7900M (180 W versus 230 W). The RX 7900M is an IGP with no power connectors, while the Pro WX 8200 is dual-slot with a 6-pin and 8-pin connector. The bus interface is PCIe 4.0 x16 on the newer card versus PCIe 3.0 x16 on the older one. Display outputs are portable-device dependent on the RX 7900M, whereas the Pro WX 8200 offers 4x mini-DisplayPort 1.4a. The release dates are separated by over five years, with the RX 7900M launching in October 2023 and the Pro WX 8200 in August 2018.

Head-to-Head Benchmarks

The head-to-head data is unambiguous. In the Geekbench OpenCL test, the RX 7900M scores 129,499, while the Pro WX 8200 scores 69,774. The delta is 85.6% in favor of the RX 7900M. This is a massive margin, indicating that compute-heavy applications like rendering, simulation, or data processing will run far faster on the newer card. The OpenCL benchmark is a general-purpose compute test, so this result reflects real-world performance in many professional tools.

In the Geekbench Vulkan test, the gap widens further. The RX 7900M achieves 158,760, while the Pro WX 8200 manages only 69,076. The delta here is 129.8%, meaning the RX 7900M is more than twice as fast in this graphics API workload. Vulkan is often used in modern game engines and compute applications, so this result suggests the RX 7900M is far better suited for current software.

Interestingly, the Pro WX 8200 has a Geekbench Metal score of 70,759, which is not part of the head-to-head comparison. That score is close to its OpenCL and Vulkan numbers, suggesting consistent performance across APIs. The RX 7900M does not have a recorded Metal score, which is expected since Metal is primarily used on Apple platforms. The recorded data shows the RX 7900M’s nearest rivals include the NVIDIA Quadro RTX 6000, which has an average score of 101,872 and a delta of -4.3%, meaning the RX 7900M is slightly behind that card. The Pro WX 8200’s nearest rival is the NVIDIA Quadro P6000, with a delta of -0.2%, indicating near-parity in average scores.

The Verdict

The data is clear: the AMD Radeon RX 7900M is the superior product in nearly every measurable way. It offers roughly double the Vulkan performance and 85.6% higher OpenCL performance than the Pro WX 8200. It has more memory, more compute units, higher clock speeds, and support for modern APIs like DirectX 12 Ultimate and Vulkan 1.4. Its lower TDP makes it more power-efficient, and it includes ray tracing cores, which the Pro WX 8200 lacks entirely.

For users who need maximum compute performance in a portable form factor, the RX 7900M is the obvious choice. Its 94th percentile ranking among all GPUs places it well above the Pro WX 8200’s 90th percentile. The RX 7900M’s nearest rivals include the NVIDIA Quadro RTX 6000 and the AMD Radeon Instinct MI60, both of which are high-end workstation or datacenter parts. This shows the RX 7900M competes in a higher tier than the Pro WX 8200, whose rivals are older cards like the NVIDIA Quadro P6000 or the AMD Radeon RX 6600 LE.

The Pro WX 8200, however, is not without merit. Its HBM2 memory on a 2048-bit bus is a unique feature that could theoretically benefit specific workloads that are sensitive to memory latency or access patterns. Its 8 GB capacity is sufficient for many professional tasks, and its dual-slot, full-length form factor is standard for workstation builds. For legacy software that may not be optimized for RDNA 3.0, the GCN 5.0 architecture might offer better compatibility. The Pro WX 8200 also has a recorded launch MSRP of 999 USD, which is factual but does not change the performance analysis.

Ultimately, the choice depends on the workload. For modern, compute-intensive tasks, the RX 7900M is overwhelmingly faster. For older, specialized workstation environments where the Pro WX 8200’s architecture is already integrated into the pipeline, the older card may still function adequately. But the benchmark results do not lie: the RX 7900M is the stronger performer across the board. The Pro WX 8200 is end-of-life, while the RX 7900M is active, suggesting AMD is investing in the newer architecture. Buyers should prioritize the RX 7900M unless they have a specific reason to stick with the older GCN-based hardware.
