AMD Radeon Pro W6600M vs AMD Radeon Pro WX 9100 Comparison

# AMD Radeon Pro WX 9100 vs AMD Radeon Pro W6600M

The AMD Radeon Pro WX 9100 and AMD Radeon Pro W6600M represent two distinct eras of AMD professional graphics, and the benchmark data reflects a clear split in workload preferences. The WX 9100, a 2017 desktop flagship built on GCN 5.0 with a 14 nm process, posts an average benchmark score of 64,212, while the W6600M, a 2021 mobile part on RDNA 2.0 with a 7 nm process, averages 61,896. That is a 3.7% gap favoring the older card, but the per-test results tell a more nuanced story. The WX 9100 dominates OpenCL with a 18.6% lead, while the W6600M counters with a 19.1% advantage in Vulkan. Both cards sit at the 89th percentile among all GPUs, meaning they occupy the same performance tier overall, but their architectures diverge sharply in compute and API efficiency.

The Verdict

The data points to a straightforward choice based on workload and form factor. For users prioritizing raw compute throughput in OpenCL applications, the AMD Radeon Pro WX 9100 is the clear winner. Its score of 66,605 in geekbench_opencl versus the W6600M's 56,140 represents an 18.6% advantage, a substantial margin that will translate into measurable gains in compute-heavy professional tasks. The WX 9100 also offers 16 GB of HBM2 memory with 483.8 GB/s bandwidth, compared to the W6600M's 8 GB of GDDR6 at 224.0 GB/s, making the desktop card markedly better suited for large datasets and memory-bandwidth-sensitive workloads.

Conversely, the AMD Radeon Pro W6600M wins decisively in Vulkan, scoring 67,652 against the WX 9100's 54,711, a 19.1% swing. This makes the mobile card the better option for Vulkan-based rendering engines, modern game development pipelines, or any workload that leverages the newer RDNA 2.0 feature set. The W6600M also carries 28 ray tracing cores, a capability the WX 9100 lacks entirely, and supports DirectX 12 Ultimate (12_2) versus the WX 9100's DirectX 12 (12_1). For mobile workstations, the W6600M's 90 W TDP and IGP slot width are decisive advantages, as the WX 9100 demands 230 W with dual-slot cooling and external power connectors.

The overall verdict: choose the WX 9100 for compute-heavy OpenCL workloads, large memory footprints, and desktop deployments where power is not a constraint. Choose the W6600M for Vulkan-centric workflows, ray tracing, modern API support, and any mobile or power-constrained environment. The 89th percentile ranking for both confirms they are peers in overall performance, but their strengths are mutually exclusive.

Architecture Differences

The architecture gap between these two GPUs is fundamental. The WX 9100 uses the Vega 10 chip built on GCN 5.0, fabricated on a 14 nm process at GlobalFoundries. The W6600M uses the Navi 23 chip on RDNA 2.0, fabricated on a 7 nm process at TSMC. This process difference is stark: 14 nm versus 7 nm, resulting in a transistor density of 25.3M per mm² for the WX 9100 versus 46.7M per mm² for the W6600M. The WX 9100 packs 12,500 million transistors on a 495 mm² die, while the W6600M crams 11,060 million transistors into a 237 mm² die, a density advantage of roughly 85% for the mobile chip.

The shading architecture differs as well. The WX 9100 has 4,096 shading units, 256 TMUs, and 64 ROPs, while the W6600M has 1,792 shading units, 112 TMUs, and 64 ROPs. Despite having fewer than half the shading units, the W6600M achieves a higher pixel rate of 130.2 GPixel/s versus 96.00 GPixel/s for the WX 9100, thanks to its higher boost clock of 2034 MHz versus 1500 MHz. The texture rate tells a different story: the WX 9100 puts out 384.0 GTexel/s, while the W6600M manages 227.8 GTexel/s. The WX 9100 also leads in raw compute with 12.29 TFLOPS FP32 and 24.58 TFLOPS FP16, against the W6600M's 7.290 TFLOPS FP32 and 14.58 TFLOPS FP16.

The W6600M introduces ray tracing cores, 28 of them, a feature entirely absent from the WX 9100. The API support differences follow: the W6600M supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the WX 9100 supports DirectX 12 (12_1) and Vulkan 1.3. Both cards support OpenGL 4.6. The bus interface also differs, with the WX 9100 on PCIe 3.0 x16 and the W6600M on PCIe 4.0 x16.

Specification Differences

The specification table highlights where these cards diverge. Process node: 14 nm for the WX 9100, 7 nm for the W6600M. Foundry: GlobalFoundries versus TSMC. Transistor count: 12,500 million versus 11,060 million. Die size: 495 mm² versus 237 mm². Transistor density: 25.3M/mm² versus 46.7M/mm².

Clock speeds differ markedly. Base clocks are close, 1200 MHz for the WX 9100 and 1224 MHz for the W6600M, but boost clocks diverge sharply: 1500 MHz versus 2034 MHz. Memory clocks also differ: 1890 Mbps effective for the WX 9100 versus 14 Gbps effective for the W6600M.

Memory configuration is a major differentiator. The WX 9100 has 16 GB of HBM2 on a 2048-bit bus with 483.8 GB/s bandwidth. The W6600M has 8 GB of GDDR6 on a 128-bit bus with 224.0 GB/s bandwidth. That is half the capacity, one-sixteenth the bus width, and less than half the bandwidth.

Compute resources diverge: 4,096 shading units versus 1,792, 256 TMUs versus 112, and 64 ROPs for both. The W6600M adds 28 ray tracing cores. Power consumption is a chasm: 230 W for the WX 9100 versus 90 W for the W6600M. The WX 9100 is dual-slot with 1x 6-pin and 1x 8-pin power connectors and a 550 W suggested PSU, while the W6600M is IGP with no power connectors and no suggested PSU.

Physical dimensions: the WX 9100 is 267 mm long and 111 mm tall, while the W6600M has no listed dimensions. Release dates: 2017-07-09 for the WX 9100, 2021-06-07 for the W6600M. The WX 9100 has a launch MSRP of 1,599 USD; the W6600M has no listed launch MSRP.

Head-to-Head Benchmarks

The head-to-head data shows exactly one win for each card, and both wins are substantial. In geekbench_opencl, the WX 9100 scores 66,605 against the W6600M's 56,140, a delta of 18.6% in favor of the desktop card. This is the larger of the two margins in absolute percentage terms, and it aligns with the WX 9100's compute advantage: 12.29 TFLOPS FP32 versus 7.290 TFLOPS FP32, and 384.0 GTexel/s versus 227.8 GTexel/s. The WX 9100's 16 GB of HBM2 with 483.8 GB/s bandwidth also provides a significant memory bandwidth advantage that likely contributes to this OpenCL lead.

In geekbench_vulkan, the tables turn completely. The W6600M scores 67,652, while the WX 9100 manages 54,711, giving the mobile card a 19.1% win. This is the single biggest delta in either direction. The W6600M's Vulkan advantage likely stems from its RDNA 2.0 architecture, which includes 28 ray tracing cores and support for Vulkan 1.4, while the WX 9100 is limited to Vulkan 1.3. The W6600M's higher boost clock of 2034 MHz and its 130.2 GPixel/s pixel rate also indicate architectural efficiency improvements that favor modern APIs.

The wins are split evenly at one apiece, and the average benchmark scores reflect this balance: 64,212 for the WX 9100 versus 61,896 for the W6600M, a 3.7% difference. The nearest rival data reinforces the competitive positioning. The WX 9100's closest rivals include the NVIDIA CMP 30HX (0.6% ahead), AMD Radeon RX 9060 XT LP (0.6% ahead), AMD Radeon RX 7600M (0.7% ahead), and AMD Radeon Pro Vega 56 (0.8% ahead). The W6600M's nearest rivals include the AMD Radeon 8050S (0.3% behind), NVIDIA GeForce RTX 4090 (2.6% behind), Intel Arc Pro A60 (2.6% behind), and AMD Radeon Pro Vega 48 (2.9% behind). Notably, the W6600M trails the RTX 4090 in average score, which underscores how competitive this mobile GPU is relative to a flagship desktop card. The data suggests a buyer should select based on API preference: OpenCL-heavy workflows favor the WX 9100, while Vulkan-centric tasks clearly favor the W6600M.
