AMD Radeon Pro WX 7100

The AMD Radeon Pro WX 7100 is a professional workstation graphics card built on the GCN 4.0 architecture, utilizing the Ellesmere chip manufactured on a 14 nm process at GlobalFoundries. With 5,700 million transistors on a 232 mm² die, this end-of-life product was released in November 2016 as part of the Radeon Pro Polaris generation, positioned between the Radeon Pro GCN and Radeon Pro Vega. The card holds a benchmark percentile of 82 among all GPUs, with an average benchmark score of 38,949 across Geekbench tests, placing it in the upper tier of workstation-class hardware despite its age.

Memory Subsystem

The Radeon Pro WX 7100 is equipped with 8 GB of GDDR5 memory, a configuration that was substantial for professional workloads at its release. The memory operates across a 256-bit bus interface, delivering a bandwidth of 224.0 GB/s. The memory clock runs at 1750 MHz, translating to 7 Gbps effective data rate, which is characteristic of the GDDR5 standard. This combination of capacity and bandwidth is particularly relevant for high-resolution rendering and large dataset manipulation, where the 8 GB frame buffer allows for complex scenes and multi-layer compositing without immediate spills to system memory.

For high-resolution work, the 224.0 GB/s bandwidth provides adequate throughput for 4K texture streaming and moderate multi-display configurations, though the data suggests it is not a bandwidth leader. The 256-bit bus width is a balanced design choice, offering more headroom than narrower 128-bit implementations while remaining cost-effective. In practical terms, the memory subsystem supports 4x DisplayPort 1.4a outputs, enabling quad-monitor setups at high resolutions, which is a common requirement in professional visualization environments. The effective 7 Gbps memory speed is modest by contemporary standards, but for the era and class of this card, it represents a solid foundation for CAD, GIS, and media processing tasks where memory capacity often matters more than raw bandwidth.

Ray Tracing and Feature Set

The Radeon Pro WX 7100 does not include dedicated ray tracing cores or tensor cores, as these hardware accelerators were not part of the GCN 4.0 architecture. Instead, the card relies on its 2304 shading units, 144 texture mapping units, and 32 raster output units to handle graphics computations. The absence of RT cores means ray-traced workloads are processed through compute shaders, which is significantly less efficient than dedicated hardware found in later generations. The feature set is defined by API support rather than specialized silicon.

The card supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, covering the major modern graphics APIs. This API compatibility ensures broad software support across professional applications, including those that leverage Vulkan for compute-heavy tasks or OpenGL for legacy CAD workflows. The pixel rate is 39.78 GPixel/s, and the texture rate is 179.0 GTexel/s, with FP32 performance at 5.728 TFLOPS and FP16 at the same 5.728 TFLOPS (1:1 ratio), indicating no half-precision acceleration advantage. For professional workloads that rely on FP32 compute, such as simulation and finite element analysis, the 5.728 TFLOPS is a measurable capability, but the lack of tensor cores limits machine learning inference performance compared to newer accelerators.

Benchmark Performance

The benchmark data reveals a tightly clustered competitive field around the WX 7100's average score of 38,949. In Geekbench Metal, the card scores 40,357, while OpenCL yields 36,807 and Vulkan 39,683, showing variance across different compute APIs. The Metal score is the strongest, suggesting favorable optimization for Apple-ecosystem applications, while OpenCL trails by approximately 9.6% compared to Metal, indicating potential driver or workload-specific inefficiencies.

Against its nearest rivals, the WX 7100 shows minimal performance separation. The NVIDIA Tesla P4 leads with an average score of 39,186, a margin of 0.6% ahead of the WX 7100 — statistically negligible and within run-to-run variance. The NVIDIA GeForce MX570 scores 38,494, placing the WX 7100 1.2% ahead. The AMD Radeon RX 7900 XT, despite being a much newer and higher-tier consumer card, scores 38,358, with the WX 7100 ahead by 1.5%. The NVIDIA GeForce RTX 5080 Mobile scores 38,349, with the WX 7100 leading by 1.6%. These deltas are remarkably small, indicating that the WX 7100's workstation drivers and memory configuration keep it competitive with these diverse rivals in synthetic benchmarks, though real-world professional application performance may diverge more significantly.

Power and Cooling

The Radeon Pro WX 7100 has a thermal design power (TDP) of 130 W, which is modest for a workstation GPU with this compute capability. The card requires a single 6-pin power connector, and AMD recommends a 300 W power supply unit for the system. This low power requirement is a notable advantage for workstation builds where multiple GPUs may be installed or where power delivery is constrained. The single-slot form factor, with a length of 241 mm (9.5 inches) and height of 112 mm (4.4 inches), allows for dense configurations in chassis designed for professional computing.

Cooling is achieved through a single-slot design, which implies a blower-style cooler that exhausts heat directly from the case. This thermal solution is adequate for the 130 W TDP, ensuring stable operation under sustained loads without excessive noise or temperature buildup. The PCIe 3.0 x16 bus interface is standard for the period, providing sufficient bandwidth for the memory and compute capabilities. For system integrators, the 300 W PSU recommendation is conservative, leaving ample headroom for other components such as high-core-count CPUs and multiple storage devices.

How It Compares

NVIDIA Tesla P4: The Tesla P4 outperforms the WX 7100 by a slim 0.6% margin in average benchmark scores. This is a near tie, suggesting that for compute-heavy workloads, the two cards are functionally equivalent in raw throughput. The Tesla P4 is a data-center-oriented card, so its similar performance to a workstation card highlights the WX 7100's competitive position in its class.

NVIDIA GeForce MX570: The WX 7100 leads the MX570 by 1.2%. The MX570 is a mobile-oriented consumer GPU, and the WX 7100's advantage, while small, indicates that the workstation card maintains a slight edge in synthetic compute tests. This delta is unlikely to translate into meaningful real-world differences for most applications.

AMD Radeon RX 7900 XT: The WX 7100 is 1.5% faster than the RX 7900 XT in average benchmark scores, which is surprising given the RX 7900 XT is a flagship consumer card from a much later generation. This result likely reflects the optimized professional drivers of the WX 7100 and the synthetic nature of Geekbench tests, which may not fully exercise the architectural advantages of the newer card.

NVIDIA GeForce RTX 5080 Mobile: The WX 7100 edges out the RTX 5080 Mobile by 1.6%. The RTX 5080 Mobile is a high-end laptop GPU, and the WX 7100's desktop-oriented design with dedicated workstation drivers appears to compensate for its older architecture in these specific benchmarks.

Who Should Consider It

The Radeon Pro WX 7100 is positioned for professionals who require reliable workstation-class performance without the power and space demands of larger cards. Given its 8 GB memory and 224.0 GB/s bandwidth, it is suitable for 1080p and 1440p professional workloads, including 3D modeling, architectural visualization, and video editing with moderate effects stacks. The 82nd percentile ranking among all GPUs indicates it outperforms the majority of graphics hardware, making it a viable option for users upgrading from integrated graphics or older discrete cards.

For high-resolution work at 4K, the memory capacity is sufficient, but the bandwidth may become a limiting factor for texture-heavy scenes or multi-display setups beyond two monitors. The lack of dedicated RT cores means users working with ray-traced renders should not expect hardware-accelerated performance; software-based ray tracing will be slow. The card is best suited for OpenGL and Vulkan-based applications where the 5.728 TFLOPS FP32 performance can be fully utilized. With a 130 W TDP and single-slot design, it is an excellent choice for compact workstations or multi-GPU systems where power and space are at a premium. The launch MSRP was 799 USD, reflecting its professional positioning at release, though as an end-of-life product, current availability and pricing vary. Users with compute-heavy workloads that rely on FP32 precision will find the WX 7100 adequate, while those needing modern ray tracing or tensor acceleration should look to newer architectures.
