AMD Radeon Pro WX 7100 vs NVIDIA GeForce RTX 3080 Ti Comparison

The NVIDIA GeForce RTX 3080 Ti and AMD Radeon Pro WX 7100 are separated by more than just their release dates; they represent entirely different design philosophies and performance tiers. The data shows a one-sided contest in raw compute, but the AMD card holds its own as a specialized workstation tool. This analysis breaks down the benchmark results, architectural disparities, and practical use-cases to help you decide which GPU aligns with your specific needs.

Head-to-Head Benchmarks

The benchmark comparison available is limited to two tests, but the results are decisive. In the Geekbench OpenCL test, the NVIDIA GeForce RTX 3080 Ti scores 170,037 points, while the AMD Radeon Pro WX 7100 manages 40,148 points. This gives the NVIDIA card a 323.5% performance advantage, a massive gap that reflects the generational and architectural chasm between the two.

The second test, Geekbench Vulkan, shows an even larger disparity. The RTX 3080 Ti produces a score of 192,697, compared to the WX 7100’s 39,683. This results in a 385.6% lead for the NVIDIA card. The delta is slightly larger in Vulkan than in OpenCL, which suggests the RTX 3080 Ti’s more modern driver stack and hardware scheduling handle compute workloads more efficiently than the older GCN architecture.

When looking at overall averages, the RTX 3080 Ti holds an avgBenchmarkScore of 41,187, placing it in the 83rd percentile of all GPUs. Its nearest rival, the NVIDIA Tesla M40 24 GB, scores 41,707 (a -1.2% delta), and the GeForce RTX 5070 scores 40,377 (a 2% delta). The WX 7100, on the other hand, has an avgBenchmarkScore of 40,063, landing in the 82nd percentile. Its closest competitor, the AMD Radeon Pro 580, scores 40,318 (-0.6% delta), while the RTX 5070 sits nearby at -0.8% delta.

Despite the single-test dominance, the average scores tell a nuanced story. The RTX 3080 Ti’s average is only 1,124 points higher than the WX 7100’s, which is a 2.8% difference. This is because the WX 7100’s benchmark suite includes a Geekbench Metal score of 40,357, which is absent for the NVIDIA card. The RTX 3080 Ti’s average is pulled up by its high compute scores, but the WX 7100’s consistent performance across OpenCL, Vulkan, and Metal keeps its average relatively close. In direct head-to-head compute, though, the RTX 3080 Ti is in a different league.

Architecture Differences

The architectural divide is stark. The NVIDIA GeForce RTX 3080 Ti is built on Ampere architecture using the GA102 chip, fabricated on Samsung’s 8 nm process node. It packs 28,300 million transistors on a 628 mm² die, yielding a transistor density of 45.1M per mm². The AMD Radeon Pro WX 7100 uses the older GCN 4.0 architecture with the Ellesmere chip, built on GlobalFoundries’ 14 nm node. It contains only 5,700 million transistors on a 232 mm² die, with a density of 24.6M per mm².

This leads to massive differences in compute resources. The RTX 3080 Ti has 10,240 shading units, 320 TMUs, and 112 ROPs. It also features 80 RT cores and 320 tensor cores, enabling hardware-accelerated ray tracing and AI workloads. The WX 7100 has just 2,304 shading units, 144 TMUs, and 32 ROPs, with no dedicated RT or tensor cores at all. This means the AMD card relies entirely on its shader array for all tasks, including any ray tracing, which it handles in software.

Clock speeds tell a similar story. The RTX 3080 Ti runs at a base clock of 1365 MHz and boosts to 1665 MHz. The WX 7100 has a base clock of 1188 MHz and a boost of 1243 MHz. The NVIDIA card’s higher clocks, combined with its massive shader count, produce a theoretical FP32 performance of 34.10 TFLOPS, compared to the WX 7100’s 5.728 TFLOPS. Both cards offer a 1:1 FP16 ratio, meaning the RTX 3080 Ti also achieves 34.10 TFLOPS in FP16, while the WX 7100 stays at 5.728 TFLOPS.

Memory is another differentiator. The RTX 3080 Ti uses 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s of bandwidth. The WX 7100 has 8 GB of GDDR5 on a 256-bit bus, providing 224.0 GB/s. The NVIDIA card’s memory clock is 1188 MHz (19 Gbps effective), while the AMD card runs at 1750 MHz (7 Gbps effective). The RTX 3080 Ti’s memory subsystem is nearly four times faster in raw bandwidth, which is critical for high-resolution textures and large datasets.

Power and physical design also diverge. The RTX 3080 Ti has a TDP of 350 W and requires a 750 W power supply, using a single 12-pin connector. It is a dual-slot card measuring 285 mm long. The WX 7100 is far more modest, with a TDP of 130 W, a suggested PSU of 300 W, and a single 6-pin connector. It is a single-slot card at 241 mm in length, making it suitable for dense workstation builds. The NVIDIA card supports PCIe 4.0 x16, while the AMD card uses PCIe 3.0 x16. Display outputs also differ: the RTX 3080 Ti has one HDMI 2.1 and three DisplayPort 1.4a outputs, while the WX 7100 offers four DisplayPort 1.4a outputs.

Where Each One Wins

Based strictly on the data, the NVIDIA GeForce RTX 3080 Ti wins in every head-to-head compute benchmark. Its 323.5% lead in OpenCL and 385.6% lead in Vulkan make it the clear choice for any task that relies on raw GPU compute power. This includes 3D rendering, scientific simulations, machine learning inference, and video encoding. The presence of RT and tensor cores gives it an advantage in ray-traced workflows and AI-accelerated applications, even though those specific workloads aren’t directly benchmarked here.

The RTX 3080 Ti also wins on memory bandwidth. With 912.4 GB/s versus 224.0 GB/s, it can feed its massive shader array far more effectively. This matters for large datasets, high-resolution textures, and any workload where memory bandwidth is the bottleneck. The 12 GB VRAM capacity is also larger than the 8 GB on the WX 7100, which is beneficial for modern game development or 3D scenes with heavy asset loads.

The AMD Radeon Pro WX 7100, however, has its own strengths. It wins on power efficiency and physical footprint. The 130 W TDP means it can be cooled passively or with a low-profile cooler, fitting into single-slot chassis. This is a significant advantage for multi-GPU workstation builds where space and thermal headroom are scarce. The four DisplayPort 1.4a outputs provide a clean multi-monitor setup without needing adapters, which is a practical benefit for professional visualization.

The WX 7100 also holds a Geekbench Metal score of 40,357, a metric not available for the RTX 3080 Ti. This suggests the AMD card is well-suited for macOS or applications that leverage Apple’s Metal API, making it a viable choice for cross-platform development or Mac Pro upgrades. Its older GCN architecture is also known for stable driver support in legacy enterprise environments, though that’s a qualitative observation not reflected in the numbers.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 3080 Ti is the superior performer in every benchmark where both cards are tested. Its 385.6% lead in Vulkan and 323.5% lead in OpenCL are overwhelming. If your priority is maximum compute performance, ray tracing, or AI acceleration, the RTX 3080 Ti is the only logical choice. Its 34.10 TFLOPS FP32 performance dwarfs the WX 7100’s 5.728 TFLOPS, and its 912.4 GB/s memory bandwidth is unmatched by the AMD card’s 224.0 GB/s.

The WX 7100 is not without merit, but its appeal is niche. Its 130 W TDP and single-slot design make it ideal for compact, low-power workstations where the RTX 3080 Ti’s 350 W TDP and dual-slot footprint would be problematic. The four DisplayPort outputs are a practical advantage for multi-display setups. Its Geekbench Metal score of 40,357 indicates solid performance in Apple-centric environments, where the RTX 3080 Ti may not be a drop-in option due to driver support.

For most builders, the choice is clear. The RTX 3080 Ti offers a 2.8% higher average benchmark score and a massive lead in compute tests. The WX 7100’s only advantages are physical and power-related, which matter only in specific workstation configurations. Choose the RTX 3080 Ti for performance; choose the WX 7100 for its compact, efficient, and Metal-compatible design.
