AMD Radeon Pro Vega II vs AMD Radeon Pro WX 9100 Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive performance gap between the AMD Radeon Pro Vega II and the AMD Radeon Pro WX 9100. Across all three recorded Geekbench tests, the Pro Vega II wins with margins that are impossible to overlook. The most extreme difference appears in the Geekbench Metal test, where the Pro Vega II scores 130,183 against the WX 9100's 71,319, a delta of 82.5%. That is not an incremental improvement; it is a generational leap in raw compute throughput for Apple's Metal API.

OpenCL results narrow the gap somewhat, but the Pro Vega II still holds a commanding lead. It records 99,048 points versus 66,605 for the WX 9100, a 48.7% advantage. This smaller margin suggests that OpenCL workloads do not scale as favorably with the Pro Vega II's architectural changes, yet the absolute score remains far ahead. Vulkan shows a similar story to Metal: the Pro Vega II achieves 99,621 points, while the WX 9100 manages only 54,711, an 82.1% difference. The consistency across APIs indicates that the performance advantage is fundamental to the hardware, not an artifact of driver optimization for a single framework.

Looking at the average benchmark scores, the Pro Vega II sits at 109,617, placing it in the 94th percentile of all GPUs in the database. The WX 9100 averages 64,212, which lands in the 89th percentile. That percentile gap is smaller than the raw score gap, reflecting how crowded the mid-range field is. The WX 9100's nearest rivals, such as the NVIDIA CMP 30HX and AMD Radeon RX 9060 XT LP, are within 0.6% of its average score, meaning the WX 9100 is tightly clustered with many contemporaries. In contrast, the Pro Vega II's nearest rival is the NVIDIA RTX A5500 Mobile, which sits 3.8% higher, and the AMD Radeon PRO W7900, which is 1% higher. The Pro Vega II also edges out its own sibling, the Radeon Pro Vega II Duo, by 2.7%, which is notable given the Duo's dual-GPU design.

The win count is clean: 3 wins for the Pro Vega II, 0 for the WX 9100. No benchmark in the database shows the WX 9100 ahead. Even the closest result, OpenCL, leaves the WX 9100 behind by nearly half. This is not a case of one card winning in specific workloads and losing in others; the Pro Vega II dominates every recorded test.

The Verdict

The data points to a clear choice for anyone prioritizing raw compute performance: the AMD Radeon Pro Vega II. It wins every benchmark in the database, often by margins exceeding 80%. Its average score of 109,617 places it near the top of the 94th percentile, and it even competes closely with the AMD Radeon PRO W7900, a newer and more expensive card, coming within 1% of that rival's average score. For workloads that rely on Metal, OpenCL, or Vulkan, the Pro Vega II is the superior option by a wide margin.

The AMD Radeon Pro WX 9100, however, is not without merit. Its 89th percentile placement and average score of 64,212 put it in line with many mid-range cards of its era. It is within 0.8% of the AMD Radeon Pro Vega 56, and its closest rivals are all within 0.7% of its score. This suggests that for applications that do not need the Pro Vega II's extreme throughput, the WX 9100 remains a competent performer. But the benchmark record shows no scenario where the WX 9100 beats the Pro Vega II. The choice is therefore straightforward: select the Pro Vega II for maximum performance, or the WX 9100 if the workload is modest and the lower power draw is a priority.

Specification Differences

The two cards differ in nearly every major specification. The Pro Vega II uses 32 GB of HBM2 memory with a 4096-bit bus and 825.3 GB/s bandwidth, while the WX 9100 has 16 GB of HBM2 with a 2048-bit bus and 483.8 GB/s bandwidth. Clock speeds also diverge: the Pro Vega II runs at a base of 1574 MHz and boosts to 1720 MHz, whereas the WX 9100 has a 1200 MHz base and 1500 MHz boost. The memory clock differs as well, with the Pro Vega II at 806 MHz (1612 Mbps effective) and the WX 9100 at 945 MHz (1890 Mbps effective).

The Pro Vega II delivers higher theoretical rates: 110.1 GPixel/s pixel fill and 440.3 GTexel/s texture fill, compared to 96.00 GPixel/s and 384.0 GTexel/s on the WX 9100. FP32 throughput is 14.09 TFLOPS versus 12.29 TFLOPS, and FP16 is 28.18 TFLOPS versus 24.58 TFLOPS. Power consumption differs sharply, with the Pro Vega II rated at 475 W and requiring an 850 W power supply, while the WX 9100 draws 230 W and needs only a 550 W PSU. The Pro Vega II is a quad-slot card with an Apple MPX bus interface, while the WX 9100 is dual-slot with a PCIe 3.0 x16 interface. Display outputs also differ: the Pro Vega II offers 1x HDMI 2.0b and 4x Thunderbolt, while the WX 9100 has 6x mini-DisplayPort 1.4a.

Architecture Differences

The underlying silicon tells a story of two process generations. The Pro Vega II uses the Vega 20 chip built on a 7 nm process at TSMC, packing 13,230 million transistors into a 331 mm² die. The WX 9100 uses the Vega 10 chip on a 14 nm process at GlobalFoundries, with 12,500 million transistors on a much larger 495 mm² die. This explains the Pro Vega II's transistor density of 40.0M per mm² versus 25.3M per mm² for the WX 9100. The smaller node allows the Pro Vega II to run at higher clocks while drawing more power, but the architecture itself is also newer: GCN 5.1 versus GCN 5.0. Both cards have identical shading units (4096), texture mapping units (256), and render output units (64), so the performance difference comes from clock speeds and memory configuration rather than core count.

The Pro Vega II's memory subsystem is far wider, with a 4096-bit bus delivering 825.3 GB/s, nearly double the WX 9100's 2048-bit bus and 483.8 GB/s. Both support DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3, so API compatibility is not a differentiator. The Pro Vega II is part of the Radeon Pro Mac (Vega Series) generation, while the WX 9100 belongs to the Radeon Pro Polaris (WX x100) line. The WX 9100's predecessor is the Radeon Pro GCN, and its successor is the Radeon Pro Vega, which indicates that the Pro Vega II represents the next evolutionary step in AMD's professional lineup.

Where Each One Wins

The AMD Radeon Pro Vega II wins in every benchmark category recorded. Its 82.5% lead in Metal and 82.1% lead in Vulkan make it the clear choice for applications built on those APIs, which includes many macOS-centric creative workflows and cross-platform Vulkan renderers. The 48.7% advantage in OpenCL is smaller but still substantial, meaning compute tasks that rely on OpenCL will also favor the Pro Vega II. With 32 GB of memory and 825.3 GB/s bandwidth, the Pro Vega II is suited for large datasets, high-resolution textures, and multi-stream video processing. Its 94th percentile ranking and proximity to the AMD Radeon PRO W7900 (within 1%) suggest it competes with much newer hardware.

The AMD Radeon Pro WX 9100, while losing all direct comparisons, still has a role. Its 230 W power draw and 550 W PSU requirement make it far easier to integrate into existing systems compared to the Pro Vega II's 475 W draw and 850 W PSU need. The WX 9100's dual-slot design and six mini-DisplayPort outputs offer flexibility for multi-display setups that the Pro Vega II's Apple MPX interface cannot match outside of Mac Pro systems. Its 89th percentile placement and tight clustering with rivals like the NVIDIA CMP 30HX (0.6% difference) and AMD Radeon RX 9060 XT LP (0.6% difference) indicate that it remains competitive within its own generation. For users who do not need the Pro Vega II's extreme compute and can accept lower performance, the WX 9100 provides a viable alternative with significantly lower power requirements and a more conventional PCIe form factor.
