AMD Radeon Pro 580 vs AMD Radeon Pro WX 7100 Comparison

# AMD Radeon Pro 580 vs AMD Radeon Pro WX 7100

The AMD Radeon Pro 580 and AMD Radeon Pro WX 7100 are near-identical twins separated by a single digit in average benchmark scores. The WX 7100 wins two of three head-to-head tests and posts a higher average score, but the Pro 580 counters with a decisive Vulkan advantage. The WX 7100 is the better all-rounder for Metal and OpenCL workloads, while the Pro 580 is the pick for Vulkan-centric applications. Both cards share the same GPU architecture, transistor count, and memory configuration, making the choice largely about workload priorities and physical form factor.

The Verdict

The data points to the AMD Radeon Pro WX 7100 as the slightly stronger overall performer. Its average benchmark score of 40,063 edges out the Pro 580’s 40,318 by a margin of 0.6% — a narrow lead, but a consistent one across two of three tests. The WX 7100 wins Geekbench Metal with 40,357 versus 39,213 (a 2.8% deficit for the Pro 580) and Geekbench OpenCL with 40,148 versus 38,457 (a 4.2% deficit). If your workflow relies primarily on Metal or OpenCL, the WX 7100 is the data-backed choice.

However, the Pro 580 is not merely a consolation prize. It delivers a commanding 9.1% victory in Geekbench Vulkan, scoring 43,285 against the WX 7100’s 39,683. That is the single largest delta between the two cards in any benchmark, and it flips the narrative for Vulkan-heavy applications. The Pro 580 also holds its own in the broader competitive landscape: its average score places it just 0.1% behind the NVIDIA GeForce RTX 5070 (40,377) and 1.4% ahead of the AMD Radeon Pro 5300 (40,870). The WX 7100, meanwhile, sits 0.8% behind the RTX 5070 and 1.3% ahead of both the NVIDIA RTX A500 Mobile and AMD Radeon Pro 575 (both at 39,568 and 39,555 respectively).

Both cards occupy the 82nd percentile among all GPUs, meaning they deliver nearly identical standing in the overall performance distribution. The verdict: choose the WX 7100 for general-purpose professional work and Metal/OpenCL pipelines; choose the Pro 580 specifically if Vulkan performance is your priority. The WX 7100 also offers a standalone card form factor, while the Pro 580 is an integrated GPU (IGP), so system integration requirements will likely decide the matter for many buyers.

Where Each One Wins

The WX 7100 wins in Metal and OpenCL. In Geekbench Metal, it scores 40,357, outperforming the Pro 580’s 39,213 by 2.8%. In Geekbench OpenCL, the margin widens to 4.2%, with the WX 7100 at 40,148 versus 38,457. These are the two most commonly used compute APIs for professional macOS and cross-platform workloads, so the WX 7100’s wins here carry substantial practical weight.

The Pro 580 wins decisively in Vulkan. Its Geekbench Vulkan score of 43,285 dwarfs the WX 7100’s 39,683, a 9.1% advantage that is the largest gap in any head-to-head test. This suggests the Pro 580’s higher boost clock configuration (or some other architectural tuning) translates into superior Vulkan execution, even though the WX 7100 has higher base and boost clocks overall.

Beyond these three benchmarks, the WX 7100 also wins on thermal efficiency. Its TDP is 130 W versus 185 W for the Pro 580 — a 55 W difference that makes the WX 7100 substantially easier to cool in a standalone chassis. The Pro 580, being an IGP with no power connectors, draws its power through the host system, while the WX 7100 requires a single 6-pin connector and a 300 W suggested PSU. For sustained compute workloads, the WX 7100’s lower power draw likely translates to better sustained performance in thermally constrained environments.

Architecture Differences

Both cards are built on the same Ellesmere chip and GCN 4.0 architecture, manufactured on GlobalFoundries’ 14 nm process. Both pack 5,700 million transistors on a 232 mm² die, yielding an identical transistor density of 24.6M per mm². The shading unit count is identical at 2,304, as are the texture mapping units (144) and render output units (32). Neither card features ray tracing cores or tensor cores — these are pure GCN compute parts.

The core specifications are nearly identical, but clock speeds differ. The WX 7100 runs at a base clock of 1188 MHz and boosts to 1243 MHz, while the Pro 580 operates at 1100 MHz base and 1200 MHz boost. This gives the WX 7100 a modest clock advantage across the board. Memory clocks also favor the WX 7100: 1750 MHz (7 Gbps effective) versus 1695 MHz (6.8 Gbps effective) for the Pro 580. Both cards use 8 GB of GDDR5 on a 256-bit bus, but the WX 7100’s higher memory clock yields 224.0 GB/s bandwidth versus 217.0 GB/s for the Pro 580.

The resulting compute rates reflect these clock differences. The WX 7100 achieves 5.728 TFLOPS FP32 (and the same FP16, at a 1:1 ratio), while the Pro 580 delivers 5.530 TFLOPS in both formats. Pixel rate is 39.78 GPixel/s for the WX 7100 versus 38.40 GPixel/s for the Pro 580, and texture rate is 179.0 GTexel/s versus 172.8 GTexel/s.

The most significant non-compute difference is form factor. The Pro 580 is an IGP — an integrated GPU with no slot width, no power connectors, and display outputs described as "Portable Device Dependent." It is designed for Apple Mac systems where the GPU is soldered to the logic board. The WX 7100, by contrast, is a single-slot, 241 mm (9.5 inches) long, 112 mm (4.4 inches) tall add-in card with 4x DisplayPort 1.4a outputs. This makes the WX 7100 a conventional workstation GPU that can be installed in a standard PCIe 3.0 x16 slot, while the Pro 580 is locked into its host device.

Head-to-Head Benchmarks

The WX 7100 wins two of three head-to-head tests, but the magnitudes tell the real story. In Geekbench OpenCL, the WX 7100 scores 40,148 against the Pro 580’s 38,457, a 4.2% advantage. This is the WX 7100’s largest win and reflects its higher clock speeds — a 1188 MHz base and 1243 MHz boost versus 1100 MHz and 1200 MHz for the Pro 580 — combined with faster memory (7 Gbps effective versus 6.8 Gbps). The 224.0 GB/s bandwidth advantage likely contributes to OpenCL performance, which often stresses memory throughput.

In Geekbench Metal, the WX 7100 wins 40,357 to 39,213, a 2.8% margin. Metal performance on GCN 4.0 tends to scale with clock speed, and the WX 7100’s higher boost clock (1243 MHz) gives it a 3.6% clock advantage over the Pro 580’s 1200 MHz boost. The fact that the Metal score delta (2.8%) closely tracks the clock delta suggests Metal is largely clock-bound for these two cards.

The Pro 580’s Vulkan win is the outlier. At 43,285 versus 39,683, the 9.1% margin is more than double the clock difference would predict. This suggests a deeper architectural or driver-level advantage for the Pro 580 in Vulkan workloads. Notably, the Pro 580’s Vulkan score (43,285) is also higher than its Metal (39,213) and OpenCL (38,457) scores, while the WX 7100’s scores cluster closely across all three APIs (40,357 Metal, 40,148 OpenCL, 39,683 Vulkan). The Pro 580’s Vulkan result is its clear standout, exceeding its own average (40,318) by 7.4%.

For context, both cards sit near the NVIDIA GeForce RTX 5070 in average score (40,377). The Pro 580 trails it by 0.1%, while the WX 7100 trails by 0.8%. The Pro 580 is 1.4% ahead of the AMD Radeon Pro 5300 (40,870), and the WX 7100 is 1.3% ahead of both the RTX A500 Mobile (39,568) and the Radeon Pro 575 (39,555). Neither card manages to beat the RTX 5070, but both remain competitive in the 82nd percentile of all GPUs.
