AMD Radeon Pro WX 8200 vs AMD Radeon RX 6650M XT Comparison

The AMD Radeon RX 6650M XT and the AMD Radeon Pro WX 8200 represent two very different philosophies in GPU design, separated by a generation of architecture and a wide gulf in power and physical footprint. The data shows a clear, but not overwhelming, victory for the newer mobile chip in the single shared benchmark, yet the Pro card’s profile suggests a specific, different purpose. The RX 6650M XT, a 7nm RDNA 2.0 part, outpaces the older 14nm GCN 5.0 Pro WX 8200 in raw compute tasks, but the WX 8200’s immense memory bandwidth and workstation pedigree make this a nuanced comparison rather than a simple one-sided affair.

Head-to-Head Benchmarks

The only direct comparison available is the Geekbench OpenCL test, and it results in a decisive win for the AMD Radeon RX 6650M XT. The RX 6650M XT scores 76,904 points, which is 10.2% higher than the Pro WX 8200’s score of 69,774. This is a substantial margin in a compute-heavy workload, indicating that the newer RDNA 2.0 architecture is significantly more efficient at executing general-purpose GPU tasks per clock. The RX 6650M XT achieves this with a far smaller die (237 mm² vs 495 mm²) and a much lower power draw (120 W vs 230 W), which reflects the architectural advancements of RDNA 2.0 over GCN 5.0.

However, the WX 8200 has its own benchmark results in other APIs that the RX 6650M XT does not have data for. In the Geekbench Metal test, the Pro WX 8200 scores 70,759, and in the Vulkan test, it scores 69,076. These scores are all remarkably consistent, hovering around the 69,000-70,000 mark. While we cannot directly compare these to the RX 6650M XT, they provide context for the WX 8200’s overall performance ceiling. The OpenCL score of 69,774 places it just 0.2% behind the NVIDIA Quadro P6000 and 0.4% behind the NVIDIA RTX A3000 Mobile, according to its nearest rivals list. This shows that while the WX 8200 loses to the RX 6650M XT, it is still a highly competitive compute card, trading blows with professional-grade NVIDIA offerings from its era.

The RX 6650M XT’s nearest rival data further contextualizes its win. Its score is only 1% behind the NVIDIA GeForce RTX 5090 D, a much more recent and powerful desktop card, and 2.6% behind its own sibling, the RX 6850M XT. This places the RX 6650M XT in rarefied air, performing nearly on par with a advanced flagship while consuming a fraction of the power. The 10.2% delta in OpenCL is the single most important data point in this comparison, as it shows that the mobile part is not just competitive but outright faster in the one metric where both are measured.

Architecture Differences

The fundamental difference between these two GPUs lies in their architecture and process technology. The RX 6650M XT is built on the RDNA 2.0 architecture using a 7 nm process at TSMC, while the Pro WX 8200 uses the older GCN 5.0 architecture on a 14 nm process at GlobalFoundries. This process node difference is a primary driver of performance and efficiency, allowing the RX 6650M XT to pack 11,060 million transistors into a 237 mm² die, yielding a transistor density of 46.7 million per mm². In contrast, the WX 8200 has 12,500 million transistors spread across a massive 495 mm² die, resulting in a much lower density of 25.3 million per mm².

These architectural changes manifest in the core configuration. The RX 6650M XT has 2048 shading units, 128 TMUs, and 64 ROPs, along with 32 dedicated ray tracing cores. The Pro WX 8200, lacking ray tracing hardware, has a higher count of 3584 shading units and 224 TMUs, but the same 64 ROPs. This is a classic generational trade-off: the GCN card uses more simple cores, while RDNA 2.0 uses fewer, more complex and efficient cores. Clock speeds tell a similar story. The RX 6650M XT has a base clock of 2068 MHz and a boost clock of 2416 MHz, while the WX 8200 is significantly slower, with a base of 1200 MHz and a boost of 1500 MHz. The higher clocks of the RDNA 2.0 part are largely responsible for its compute advantage.

Memory architecture also starkly contrasts. The RX 6650M XT uses 8 GB of GDDR6 memory on a 128-bit bus, providing 256.0 GB/s of bandwidth. The Pro WX 8200, however, uses 8 GB of HBM2 memory on a massive 2048-bit bus, delivering exactly double the bandwidth at 512.0 GB/s. This is the WX 8200’s key advantage; the sheer memory bandwidth is designed for large, complex datasets that are common in professional workloads. The WX 8200 also has a wider PCIe interface (PCIe 3.0 x16 vs PCIe 4.0 x8), which matters for data transfer in a desktop workstation environment.

Where Each One Wins

Based on the data, the AMD Radeon RX 6650M XT wins decisively in compute performance and efficiency. Its 10.2% lead in OpenCL, combined with its significantly lower TDP of 120 W versus 230 W and its smaller physical footprint (IGP vs Dual-slot), makes it the superior choice for tasks that rely on raw shader throughput and power efficiency. Its support for DirectX 12 Ultimate (12_2) and Vulkan 1.4 also gives it a modern feature set that the WX 8200 lacks, which only supports DirectX 12 (12_1) and Vulkan 1.3. This suggests the RX 6650M XT is better suited for gaming, real-time rendering, and any workload that leverages the latest graphics APIs.

The AMD Radeon Pro WX 8200 wins in the domain of memory bandwidth and professional ecosystem integration. Its 512.0 GB/s of HBM2 bandwidth is a massive advantage for memory-bound workloads like large-scale data visualization, scientific computing, and complex CAD or DCC tasks where data doesn’t fit comfortably in a smaller cache. Its 4x mini-DisplayPort 1.4a outputs are a clear pro-workstation feature, allowing for multi-display setups out of the box, whereas the RX 6650M XT’s outputs are listed as "Portable Device Dependent." The WX 8200’s nearest rivals include the NVIDIA Quadro P6000 and RTX A3000 Mobile, placing it in the professional GPU tier, where software certification and stability are expected. It also has a higher FP32 throughput at 10.75 TFLOPS compared to the RX 6650M XT’s 9.896 TFLOPS, suggesting that in specific, highly parallelized FP32 operations, it could potentially outperform the newer card despite the lower OpenCL score.

The Verdict

The data presents a clear choice for different use cases. For a mobile workstation or a high-performance gaming laptop, the AMD Radeon RX 6650M XT is the obvious winner. It delivers superior compute performance in OpenCL, supports modern APIs like DirectX 12 Ultimate and Vulkan 1.4, and does so while consuming nearly half the power of its competitor. Its 10.2% benchmark lead is significant, and its smaller footprint and mobile-ready design make it a versatile and modern component. Anyone prioritizing raw compute speed, feature support, and efficiency in a compact form factor should choose the RX 6650M XT.

Conversely, the AMD Radeon Pro WX 8200 is a specialist tool. Its 512.0 GB/s of HBM2 bandwidth is a massive asset for data-heavy professional applications, and its workstation-oriented features like 4x mini-DisplayPort outputs and a dual-slot design are tailored for a desktop environment. While its OpenCL score is lower, its higher FP32 rating of 10.75 TFLOPS suggests it may excel in specific compute tasks that are not fully represented by the Geekbench test. For a professional user whose work is bottlenecked by memory bandwidth and who needs a stable, multi-display desktop solution in a professional GPU ecosystem, the Pro WX 8200’s specialized capabilities make it the more appropriate choice, despite its older architecture and higher power draw.
