AMD Radeon Pro W5700X vs AMD Radeon RX 6650M Comparison

AMD Radeon RX 6650M and AMD Radeon Pro W5700X occupy different corners of the AMD graphics lineup. The RX 6650M is a mobile-focused part built on RDNA 2.0, while the Pro W5700X is a workstation-oriented card for Apple systems using the older RDNA 1.0 architecture. The database records show a clear performance gap between the two, but the story is more nuanced than a simple winner and loser. The RX 6650M leads in the two shared benchmark tests, yet the Pro W5700X brings a very different set of specifications that matter for specific workloads. This analysis breaks down where each card wins, the architectural differences, and what the recorded numbers actually mean.

Where Each One Wins

The RX 6650M wins both head-to-head benchmark comparisons in the database. In the Geekbench OpenCL test, the RX 6650M scores 65,800 against the Pro W5700X's 43,810, a 50.2% advantage. In Geekbench Vulkan, the margin grows even larger: 77,735 versus 45,246, a 71.8% lead. These are substantial wins, and they place the RX 6650M well ahead in raw compute throughput as measured by these synthetic workloads.

However, the Pro W5700X has its own strong suit. The database includes a Geekbench Metal score for the Pro W5700X of 75,427. This is the only Metal benchmark recorded for either card, and it shows the Pro W5700X performing at a level comparable to the RX 6650M's Vulkan result. For users in Apple-centric ecosystems that rely on Metal, the Pro W5700X is clearly the more capable option. The RX 6650M has no Metal score in the database, so any comparison on that API is one-sided.

Beyond benchmark scores, the Pro W5700X offers 16 GB of memory versus 8 GB on the RX 6650M. That doubles the frame buffer, which directly benefits workloads that need large datasets resident on the GPU, such as high-resolution rendering, large model compilation, or complex compositing. The Pro W5700X also has a 256-bit memory bus and 448.0 GB/s of bandwidth, compared to the RX 6650M's 128-bit bus and 224.0 GB/s. In memory-bound tasks, the Pro W5700X has a definitive structural advantage.

For raw compute density, the RX 6650M wins. Its FP32 throughput is 8.659 TFLOPS, and its FP16 throughput reaches 17.32 TFLOPS with a 2:1 ratio. The Pro W5700X counters with 10.44 TFLOPS FP32 and 20.89 TFLOPS FP16, so it actually has higher raw floating-point numbers. Yet the benchmark results show the RX 6650M outperforming in OpenCL and Vulkan. This suggests the RX 6650M's newer architecture, RDNA 2.0, extracts more real-world performance per shader, clock, and transistor than the older RDNA 1.0 in the Pro W5700X.

Architecture Differences

The RX 6650M uses the Navi 23 chip, built on RDNA 2.0 architecture, while the Pro W5700X uses Navi 10, built on the first-generation RDNA 1.0. Both are manufactured on a 7 nm process at TSMC, but the similarities end there. The RX 6650M has 11,060 million transistors on a 237 mm² die, giving a transistor density of 46.7M per mm². The Pro W5700X has 10,300 million transistors on a larger 251 mm² die, resulting in a lower density of 41.0M per mm². The RX 6650M packs more transistors into a smaller area, reflecting the architectural efficiency gains of RDNA 2.0.

Shader configuration differs significantly. The RX 6650M has 1,792 shading units, 112 texture mapping units, and 64 raster operations pipelines. The Pro W5700X has 2,560 shading units, 160 TMUs, and also 64 ROPs. Despite having fewer shading units and TMUs, the RX 6650M achieves higher benchmark scores. This points to a higher instruction-per-clock efficiency in RDNA 2.0, as well as the much higher clock speeds on the RX 6650M.

The RX 6650M has a base clock of 2068 MHz, a boost clock of 2416 MHz, and a game clock of 2222 MHz. The Pro W5700X runs at a base clock of 1243 MHz and a boost clock of 2040 MHz. The RX 6650M's base clock is nearly 66% higher than the Pro W5700X's base, and its boost clock is about 18% higher. That clock advantage, combined with the architectural improvements, explains why the RX 6650M dominates in the recorded benchmark scores.

Ray tracing is another key differentiator. The RX 6650M includes 28 ray tracing cores, a hallmark of RDNA 2.0. The Pro W5700X has no ray tracing cores listed in the database. This means the RX 6650M can handle hardware-accelerated ray tracing workloads, while the Pro W5700X must rely on software or compute-based approaches. For any application using DirectX Raytracing or Vulkan ray tracing, the RX 6650M is the only one of the two with dedicated hardware support.

The RX 6650M also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4. The Pro W5700X supports DirectX 12 (12_1) and Vulkan 1.4. The DirectX feature level difference means the RX 6650M can access features like mesh shaders, variable rate shading, and other DirectX 12 Ultimate capabilities, none of which are available on the Pro W5700X.

Head-to-Head Benchmarks

The database records two direct comparisons between the RX 6650M and the Pro W5700X. Both are decisive wins for the RX 6650M. In Geekbench OpenCL, the RX 6650M scores 65,800 against the Pro W5700X's 43,810, a 50.2% difference. In Geekbench Vulkan, the RX 6650M scores 77,735 against the Pro W5700X's 45,246, a 71.8% difference.

The Vulkan margin is particularly striking. The RX 6650M outperforms the Pro W5700X by nearly three-quarters of the latter's own score. This likely stems from the combination of RDNA 2.0 efficiency, the 28 ray tracing cores, and the much higher clock speeds. The Pro W5700X has more shading units and higher theoretical FP32 throughput, but it cannot translate that into a Vulkan advantage.

The OpenCL result, while still a clear win for the RX 6650M, is closer in relative terms. The 50.2% lead suggests that OpenCL workloads are somewhat less sensitive to the architectural differences, or that the Pro W5700X's larger memory bandwidth helps narrow the gap in memory-intensive OpenCL tasks. Still, the RX 6650M remains firmly ahead.

For the Pro W5700X, the only recorded benchmark win is the Geekbench Metal score of 75,427. Since the RX 6650M has no Metal score, this is not a head-to-head comparison, but it does show the Pro W5700X's strength in Apple's API. That score is higher than the RX 6650M's OpenCL score of 65,800 and close to its Vulkan score of 77,735. In a Metal-only environment, the Pro W5700X would be competitive with the RX 6650M's performance levels.

The average benchmark score in the database reflects the overall picture. The RX 6650M has an average benchmark score of 71,768, placing it in the 91st percentile of all GPUs. The Pro W5700X has an average benchmark score of 54,828, in the 87th percentile. The RX 6650M sits about 31% higher in average score. Its nearest rivals in the database include the NVIDIA TITAN X Pascal at 72,098 (0.5% lower), the AMD Radeon Pro Vega 64 at 72,379 (0.8% lower), the AMD Radeon RX 6600 LE at 70,829 (1.3% higher), and the AMD Radeon Vega Frontier Edition at 73,370 (2.2% lower). The Pro W5700X's nearest rivals include the NVIDIA GeForce RTX 4080 at 54,247 (1.1% higher), the NVIDIA GeForce RTX 4080 SUPER at 54,209 (1.1% higher), the AMD Radeon RX 6750 GRE 12 GB at 55,698 (1.6% lower), and the AMD Radeon 8060S at 55,757 (1.7% lower).

These rival comparisons show the RX 6650M performing in a class well above the Pro W5700X. The Pro W5700X, despite its workstation branding and 16 GB memory, sits near the RTX 4080 and RX 6750 GRE in average score, while the RX 6650M trades blows with the TITAN X Pascal and Vega Frontier Edition. The data is clear: for OpenCL and Vulkan, the RX 6650M is the superior choice, while the Pro W5700X only shines in Metal-specific environments.
