AMD Radeon Pro 575X vs AMD Radeon Pro WX 7100 Comparison

AMD Radeon Pro WX 7100 and AMD Radeon Pro 575X are both end-of-life professional GPUs built on the same GCN 4.0 architecture and 14 nm process, yet they serve distinctly different purposes. The data shows a clear split: the WX 7100 takes two of three benchmark wins with decisive margins in OpenCL and Vulkan, while the 575X counters with a significant Metal victory. Neither card dominates outright; instead, the choice hinges on workload and platform.

The Verdict

From the benchmark data, the AMD Radeon Pro WX 7100 is the stronger all-round compute card. It wins the OpenCL test with a 15.5% delta over the 575X (40148 vs 34773) and the Vulkan test by 4.7% (39683 vs 37919). Its average benchmark score of 40063 also edges out the 575X's 39116. For professionals running OpenCL-heavy applications or Vulkan-based workloads, the WX 7100 is the clear pick. The 575X, however, is not without merit: its 44655 Metal score beats the WX 7100's 40357 by 9.6%, making it the superior choice for Apple ecosystem workflows that leverage Metal. The 575X is an integrated part of a portable device (IGP slot width, no power connectors), so it targets Mac users who need a capable GPU without expansion options. The WX 7100, with its single-slot design, 1x 6-pin power connector, and 300 W suggested PSU, suits desktop workstations where discrete, user-serviceable graphics are required. Ultimately, the WX 7100 wins on raw compute versatility; the 575X wins specifically on Metal performance for Mac-centric tasks.

Architecture Differences

Both GPUs share the Ellesmere chip, GCN 4.0 architecture, 14 nm process from GlobalFoundries, 5,700 million transistors, and a 232 mm² die size with a transistor density of 24.6M / mm². The similarities end at the core configuration. The WX 7100 packs 2304 shading units, 144 texture mapping units, and 32 ROPs, while the 575X has fewer: 2048 shading units, 128 TMUs, and the same 32 ROPs. This translates to higher theoretical throughput for the WX 7100: 5.728 TFLOPS FP32 and FP16 (1:1) versus 4.489 TFLOPS for the 575X. Pixel rate is also higher on the WX 7100 at 39.78 GPixel/s versus 35.07 GPixel/s, and texture rate is 179.0 GTexel/s versus 140.3 GTexel/s. Clock speeds differ notably: the WX 7100 runs at 1188 MHz base and 1243 MHz boost, while the 575X has no listed base or boost clocks, only a memory clock of 1695 MHz (6.8 Gbps effective) versus the WX 7100's 1750 MHz (7 Gbps effective). Memory configuration diverges sharply: the WX 7100 has 8 GB GDDR5 on a 256-bit bus with 224.0 GB/s bandwidth; the 575X has 4 GB GDDR5 on the same 256-bit bus but with slightly lower 217.0 GB/s bandwidth. Power profiles also differ: the WX 7100 is rated at 130 W TDP with a single-slot cooler and 1x 6-pin connector, while the 575X is an IGP (integrated graphics processor) rated at 150 W TDP with no power connectors and portable-device-dependent display outputs. Both support PCIe 3.0 x16, DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The WX 7100 offers 4x DisplayPort 1.4a outputs; the 575X's outputs are determined by the host device.

Head-to-Head Benchmarks

The three Geekbench tests reveal a polarized performance profile. The most dramatic gap is in OpenCL, where the WX 7100 scores 40148 against the 575X's 34773, a 15.5% advantage. This is the largest delta in the entire comparison and aligns with the WX 7100's higher shading unit count (2304 vs 2048) and greater memory capacity (8 GB vs 4 GB). The Vulkan test also favors the WX 7100, though by a narrower 4.7% margin (39683 vs 37919). This suggests that the WX 7100's compute advantages translate to cross-platform graphics APIs, but the gap narrows as the workload shifts from pure compute (OpenCL) to graphics-oriented compute (Vulkan). The 575X strikes back decisively in Metal, scoring 44655 versus the WX 7100's 40357, a 9.6% win. This is a curious inversion: the 575X has fewer shading units and lower FP32 throughput, yet it outperforms in Metal. The data indicates that Metal optimization favors the 575X's specific configuration, possibly due to driver maturity or architectural tuning for Apple's API. Notably, the 575X's Metal score (44655) is its highest across all three tests, while the WX 7100's scores are tightly clustered (39683 to 40357). The WX 7100 wins 2 of 3 tests, but the 575X's Metal dominance is significant enough to matter for Mac-centric workflows. Looking at nearest rivals, the WX 7100 sits within 1.3% of the AMD Radeon Pro 575 (39555) and RTX A500 Mobile (39568), and within 0.8% of the NVIDIA GeForce RTX 5070 (40377). The 575X also lands within 1.1% of the Pro 575 and RTX A500 Mobile, showing both cards are closely matched to the same competitive tier.

Where Each One Wins

The AMD Radeon Pro WX 7100 is the winner for compute-heavy professional workloads. Its 15.5% OpenCL advantage and 4.7% Vulkan lead make it the better choice for general-purpose GPU compute, rendering, and cross-platform applications that rely on OpenCL or Vulkan. The 8 GB memory capacity is a significant asset for larger datasets and textures, and the 224.0 GB/s bandwidth provides faster memory access. The WX 7100's discrete, single-slot design with 4x DisplayPort 1.4a outputs makes it suitable for multi-monitor desktop workstations. It also holds a slight edge in average benchmark score (40063 vs 39116) and sits at the 82nd percentile, same as the 575X. For users who need a flexible, high-throughput GPU for OpenCL compute, the WX 7100 is the data-backed choice.

The AMD Radeon Pro 575X wins exclusively on Metal performance, with a 9.6% lead over the WX 7100 in Geekbench Metal. This makes it the preferred option for macOS environments where Metal is the primary API. Its integrated nature (IGP slot, no power connectors, portable-device-dependent outputs) means it is designed for laptops or all-in-one systems where expansion is impossible. The 575X's lower shading unit count and FP32 throughput are offset by its Metal optimization, indicating that Apple's driver stack extracts more from this configuration in Metal-specific tasks. However, the 575X trails in OpenCL by a wide margin and has half the memory (4 GB vs 8 GB) and lower bandwidth (217.0 GB/s vs 224.0 GB/s), limiting its utility for large-scale compute. The 575X also has a higher TDP (150 W vs 130 W), which is notable for a portable device. In summary, the 575X wins where Metal matters; the WX 7100 wins everywhere else.
