AMD Radeon PRO W7600 vs AMD Radeon Pro WX 9100 Comparison

The Verdict

The benchmark data separates these two professional GPUs clearly. The AMD Radeon PRO W7600 is the stronger performer in every recorded test, and it does so while being the more modern and efficient product. The AMD Radeon Pro WX 9100, while still a capable card, is outclassed in raw compute and API compatibility. The W7600 wins both head-to-head benchmark comparisons, with a 22.4% lead in Geekbench OpenCL and a substantial 69.4% lead in Geekbench Vulkan. Its average benchmark score of 87108 places it in the 93rd percentile of all GPUs, while the WX 9100's average of 64212 lands in the 89th percentile. For any professional workload that relies on OpenCL or Vulkan, the W7600 is the clear choice from this data. The WX 9100 retains an advantage in memory capacity and bandwidth, which could matter for specific large-data tasks, but its compute performance is decisively lower. The verdict is straightforward: the Radeon PRO W7600 is the superior investment for current and future workloads, while the WX 9100 should only be considered if the larger 16 GB memory pool is an absolute requirement and the lower compute throughput is acceptable.

Architecture Differences

The two cards represent vastly different eras of AMD GPU design. The Radeon PRO W7600 uses the Navi 33 chip built on the RDNA 3.0 architecture, manufactured on a 6 nm process at TSMC. The Radeon Pro WX 9100 uses the Vega 10 chip based on the older GCN 5.0 architecture, produced on a 14 nm process at GlobalFoundries. This generational gap is reflected in transistor density: the W7600 packs 13,300 million transistors into a 204 mm² die for a density of 65.2 million transistors per square millimeter, while the WX 9100 has 12,500 million transistors across a much larger 495 mm² die, yielding only 25.3 million per square millimeter. The W7600's die is less than half the physical size yet contains more transistors, a direct result of the newer process node.

The compute layouts differ sharply. The W7600 features 2048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. The WX 9100 has double the shading units at 4096, double the TMUs at 256, and the same 64 ROPs, but it has no ray tracing cores at all. Clock speeds tell the rest of the story: the W7600 runs at a base of 1720 MHz with a boost of 2440 MHz, while the WX 9100 operates at 1200 MHz base and 1500 MHz boost. The architectural efficiency of RDNA 3.0 allows the W7600 to achieve higher performance with fewer, faster cores. The W7600 also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the WX 9100 is limited to DirectX 12 (12_1) and Vulkan 1.3. Both support OpenGL 4.6. The W7600 is an active production part released on August 2, 2023, whereas the WX 9100 is end-of-life, having launched on July 9, 2017. The WX 9100's predecessor is Radeon Pro GCN and its successor is Radeon Pro Vega; the W7600's predecessor is Radeon Pro Vega. This positions the W7600 as the direct evolution from the WX 9100's lineage.

Head-to-Head Benchmarks

The recorded head-to-head data shows a decisive sweep for the Radeon PRO W7600. In Geekbench OpenCL, the W7600 scores 81528 against the WX 9100's 66605, a 22.4% advantage. This margin indicates a substantial generational improvement in raw compute throughput, not a marginal edge. The W7600's FP32 performance of 19.99 TFLOPS versus the WX 9100's 12.29 TFLOPS supports this gap, representing a 63% higher peak single-precision output. The W7600 also leads in pixel fill rate at 156.2 GPixel/s versus 96.00 GPixel/s, a 63% difference, and in texture rate at 312.3 GTexel/s versus 384.0 GTexel/s, where the WX 9100 actually holds a 23% lead due to its higher TMU count and texture-oriented design.

The Geekbench Vulkan result is far more lopsided. The W7600 scores 92688, while the WX 9100 manages only 54711, a 69.4% delta. This massive difference reflects not just raw compute but also architectural maturity in handling modern graphics APIs. The W7600's ray tracing cores and RDNA 3.0 feature set allow it to execute Vulkan workloads far more efficiently. In contrast, the WX 9100's GCN 5.0 architecture, with no ray tracing support and older API compliance, struggles to keep pace. The W7600's FP16 performance of 39.98 TFLOPS versus the WX 9100's 24.58 TFLOPS (both at 2:1 ratio) further underscores the compute advantage. The W7600 also has a higher average benchmark score of 87108 compared to the WX 9100's 64212, a 35.6% overall lead. Looking at the nearest rivals in the database, the W7600 sits within 5% of the NVIDIA RTX A4500 and RTX A4500 Mobile, while the WX 9100 trades within 0.8% of the AMD Radeon Pro Vega 56 and Radeon RX 7600M. This contextualizes the W7600 as a modern mid-range professional card, while the WX 9100 is now comparable to entry-level current products.

Specification Differences

The core specifications diverge on nearly every measurable parameter. The W7600 uses 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The WX 9100 uses 16 GB of HBM2 memory on a 2048-bit bus, delivering 483.8 GB/s. The WX 9100's memory bandwidth is 68% higher, and its capacity is double, which is its one clear hardware advantage. Memory clock rates reflect the different technologies: the W7600 runs at 2250 MHz with 18 Gbps effective, while the WX 9100 runs at 945 MHz with 1890 Mbps effective. The HBM2's wide bus compensates for the lower clock speed.

Power and physical characteristics differ substantially. The W7600 has a TDP of 130 W and requires a single 6-pin power connector with a suggested 300 W PSU. It is a single-slot card measuring 241 mm in length and 115 mm in height. The WX 9100 has a TDP of 230 W, needs one 6-pin and one 8-pin connector, and recommends a 550 W PSU. It is a dual-slot card at 267 mm long and 111 mm tall. The W7600 is thus more power-efficient and physically smaller, which matters for compact workstation builds. The bus interface also differs: the W7600 uses PCIe 4.0 x8, while the WX 9100 uses PCIe 3.0 x16. The newer standard provides higher bandwidth per lane, though the x8 width limits total throughput compared to a full x16 slot.

Display outputs are another differentiator. The W7600 offers 4x DisplayPort 2.1, supporting the latest display standard. The WX 9100 offers 6x mini-DisplayPort 1.4a, which provides more physical outputs but on an older protocol. This makes the W7600 better suited for modern high-resolution, high-refresh monitors, while the WX 9100 may appeal to setups needing many simultaneous displays. The launch MSRP for the W7600 was 599 USD, while the WX 9100 launched at 1,599 USD. This price difference historically positioned the WX 9100 as a higher-tier product, but the performance data shows the W7600 now exceeds it in compute.
