AMD Radeon Pro WX 9100 vs AMD Radeon RX Vega 64 Comparison

Head-to-Head Benchmarks

The direct comparison between the AMD Radeon Pro WX 9100 and the AMD Radeon RX Vega 64 is not a clean sweep for either card. The recorded data shows the professional-focused WX 9100 takes two of the three shared benchmark tests, while the consumer-oriented RX Vega 64 claims one decisive victory. Both cards share the same Vega 10 chip and GCN 5.0 architecture, so the differences come down to clock speeds, memory configuration, and driver tuning.

The WX 9100 leads in Geekbench Metal with a score of 71,319 against 68,750 for the RX Vega 64, a margin of 3.7%. That is a modest but consistent advantage in Apple's compute API, suggesting the Pro card's driver stack and memory setup handle Metal workloads slightly better. The gap widens in Geekbench OpenCL, where the WX 9100 scores 66,605 versus 62,552, a 6.5% lead. OpenCL is the legacy compute standard that many professional applications still rely on, and the data shows the WX 9100 has a clear edge there.

The RX Vega 64 strikes back hard in Geekbench Vulkan. It scores 67,032 against the WX 9100's 54,711, which is an 18.4% swing in favor of the consumer card. That is the largest single-test delta in the head-to-head set, and it flips the overall narrative. Vulkan is the modern cross-platform graphics and compute API, and the RX Vega 64's higher boost clock appears to give it a substantial advantage in this workload. The WX 9100's lower clock speeds, likely tuned for stability and thermal headroom in professional environments, hurt it here.

Looking at the average benchmark scores across all recorded tests, the WX 9100 posts 64,212, while the RX Vega 64 averages 50,001. That 14,211-point gap is driven partly by the RX Vega 64's inclusion of a 3DMark Steel Nomad DX12 result (1,669) that drags down its average, while the WX 9100 has no comparable low-scoring test in its record. The percentile rankings tell a similar story: the WX 9100 sits at the 89th percentile among all GPUs, while the RX Vega 64 sits at the 86th. Both are high-end parts, but the Pro card edges out the consumer card in overall standing.

What the head-to-head data does not show is a single dominant winner. The WX 9100 wins the compute-heavy APIs, and the RX Vega 64 wins the modern graphics API by a wide margin. A buyer choosing between these two should not assume the higher average score tells the whole story. The specific application's API usage matters more than the aggregate number.

The Verdict

The data supports a clear split: pick the AMD Radeon Pro WX 9100 for compute-heavy professional workloads and multi-display configurations, and pick the AMD Radeon RX Vega 64 for Vulkan-based applications or gaming. The WX 9100 wins Geekbench Metal by 3.7% and Geekbench OpenCL by 6.5%, both of which are APIs heavily used in content creation, scientific computing, and engineering tools. The RX Vega 64 wins Geekbench Vulkan by 18.4%, a massive margin that makes it the better choice for Vulkan-native games or compute tasks that leverage that API.

The WX 9100's 16 GB memory capacity doubles the RX Vega 64's 8 GB, which matters for large datasets or high-resolution textures that exceed 8 GB. The RX Vega 64 counters with higher boost clocks (1546 MHz versus 1500 MHz) and higher FP32 throughput (12.66 TFLOPS versus 12.29 TFLOPS), which explains its Vulkan advantage. Power consumption also differs significantly: the RX Vega 64 draws 295 W and needs a 600 W PSU, while the WX 9100 draws 230 W and works with a 550 W PSU. The Pro card is more efficient per watt on paper.

The nearest rivals in the database reinforce the positioning. The WX 9100 sits within 0.6% to 0.8% of the NVIDIA CMP 30HX, the AMD Radeon RX 9060 XT LP, the AMD Radeon RX 7600M, and the AMD Radeon Pro Vega 56, all of which cluster tightly around its average score. The RX Vega 64 sits within 0.1% of the NVIDIA GeForce RTX 5070 Ti, 0.5% of the Intel Arc A550M, and falls 1.9% behind the AMD Radeon RX 6900 XT while leading the AMD Radeon RX 6800 XT by 3.1%. This shows the RX Vega 64 is competitive with much newer hardware, while the WX 9100 trades blows with a mix of older and newer professional and consumer cards.

Specification Differences

The two cards share a great deal of silicon, but several specifications diverge. Memory capacity is the biggest difference: the WX 9100 carries 16 GB of HBM2, while the RX Vega 64 carries 8 GB. Both use a 2048-bit bus and deliver 483.8 GB/s bandwidth, so the capacity difference does not affect raw throughput.

Clock speeds favor the RX Vega 64. Its base clock is 1247 MHz and boost clock is 1546 MHz, compared to the WX 9100's 1200 MHz base and 1500 MHz boost. This translates to higher fill rates: the RX Vega 64 reaches 98.94 GPixel/s and 395.8 GTexel/s, while the WX 9100 manages 96.00 GPixel/s and 384.0 GTexel/s. FP32 compute also leans toward the RX Vega 64 at 12.66 TFLOPS versus 12.29 TFLOPS, and FP16 follows at 25.33 TFLOPS versus 24.58 TFLOPS.

Power delivery is another split. The WX 9100 has a 230 W TDP with a single 6-pin and single 8-pin connector, and a suggested 550 W PSU. The RX Vega 64 has a 295 W TDP with two 8-pin connectors and a suggested 600 W PSU. Physical dimensions differ slightly: the WX 9100 is 267 mm (10.5 inches) long, while the RX Vega 64 is 280 mm (11 inches) long, with the RX Vega 64 also having a listed 40 mm (1.6 inch) width. Both are dual-slot cards.

Display outputs are a major differentiator. The WX 9100 has six mini-DisplayPort 1.4a outputs, clearly aimed at multi-monitor professional setups. The RX Vega 64 has one HDMI 2.0b and three DisplayPort 1.4a outputs, the standard consumer configuration. Release dates are close: the WX 9100 launched July 9, 2017, and the RX Vega 64 launched August 6, 2017. The WX 9100's predecessor is the Radeon Pro GCN and its successor is the Radeon Pro Vega, while the RX Vega 64's predecessor is Polaris and its successor is Navi.

Architecture Differences

Both cards are built on the same Vega 10 chip, use the GCN 5.0 architecture, and are fabricated by GlobalFoundries on a 14 nm process. The transistor count is identical at 12,500 million, and the die size is the same at 495 mm², yielding a transistor density of 25.3 million per square millimeter. Shading units, texture mapping units, and render output units are all identical: 4096 shaders, 256 TMUs, and 64 ROPs.

The core architecture is therefore the same, but the surrounding platform differs. The WX 9100 belongs to the Radeon Pro Polaris (WX x100) generation, while the RX Vega 64 belongs to the Vega (RX Vega) generation. This naming difference reflects the intended use case rather than a fundamental silicon change. The WX 9100 is a workstation card with a professional driver certification path, while the RX Vega 64 is a consumer gaming card with standard drivers.

Both support the same API set: DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. Neither card has dedicated ray tracing cores or tensor cores, as those features did not exist in this architecture generation. The memory subsystem is also architecturally identical: HBM2 on a 2048-bit bus with 483.8 GB/s bandwidth. The only memory difference is capacity, which is a board-level decision, not an architectural one.

The process node, foundry, and transistor density are all matching numbers. The difference in power consumption (295 W for RX Vega 64 versus 230 W for WX 9100) likely stems from clock speed tuning and the driver's power management profile rather than a physical difference in the silicon. The WX 9100 runs lower clocks, which reduces power draw and heat output, a trade-off that suits long-duration professional workloads. The RX Vega 64 runs higher clocks, which increases power draw but boosts raw performance in bursty workloads like gaming.

Where Each One Wins

The AMD Radeon Pro WX 9100 wins in compute-oriented professional scenarios. Its 16 GB memory capacity handles datasets that would overflow the RX Vega 64's 8 GB buffer. Its OpenCL lead of 6.5% makes it the better choice for applications that rely on OpenCL compute kernels, such as many rendering engines, scientific simulation tools, and machine learning frameworks that predate Vulkan support. The Metal advantage of 3.7% also favors the WX 9100 for macOS or iOS development environments where Metal is the primary API.

The WX 9100's six mini-DisplayPort outputs make it the clear winner for multi-monitor workstations. A professional running six displays for financial trading, video editing timelines, or CAD layouts gets that capability out of the box. The lower 230 W TDP and 550 W PSU requirement also make it easier to integrate into existing workstation builds without upgrading the power supply.

The AMD Radeon RX Vega 64 wins in Vulkan-based workloads. Its 18.4% lead in Geekbench Vulkan is decisive, and it extends to any game or application that uses Vulkan for rendering or compute. The higher boost clock of 1546 MHz and higher FP32 throughput of 12.66 TFLOPS give it an edge in scenarios that scale with raw shader throughput rather than memory capacity. The RX Vega 64's consumer display outputs (one HDMI and three DisplayPort) are more practical for a standard desktop setup with a single high-refresh monitor or a triple-monitor gaming rig.

The RX Vega 64 also wins on efficiency of performance per dollar in a general sense, though the database does not record pricing beyond launch MSRP. The RX Vega 64's nearest rivals include the NVIDIA GeForce RTX 5070 Ti (within 0.1%) and the AMD Radeon RX 6900 XT (1.9% ahead), which shows it competes with much newer high-end cards. The WX 9100's nearest rivals, including the NVIDIA CMP 30HX and AMD Radeon RX 9060 XT LP, are a mix of mining and modern GPU parts, indicating a tighter performance cluster.

For power-sensitive builds, the WX 9100 is the better choice. Its 230 W TDP is 65 W lower than the RX Vega 64's 295 W, and it requires a 550 W PSU instead of 600 W. For raw Vulkan performance or gaming, the RX Vega 64 is the better choice despite its higher power draw. The data does not support one card as universally superior; it supports each card winning in its intended domain.
