AMD Radeon Pro WX 7100 vs NVIDIA GeForce RTX 4070 Comparison

The AMD Radeon Pro WX 7100 and NVIDIA GeForce RTX 4070 represent two very different eras of GPU design, and the benchmark data reflects that clearly. The WX 7100 is an end-of-life workstation card from 2016, while the RTX 4070 is a newer, end-of-life consumer card from 2023. The data shows a massive performance gulf between them, but the WX 7100 still holds a niche for specific legacy workloads. This analysis breaks down where each card wins, the architectural chasm between them, and what the numbers mean for a prospective buyer.

Where Each One Wins

The RTX 4070 dominates the head-to-head benchmarks outright, winning both of the tests where a direct comparison exists. In Geekbench OpenCL, the RTX 4070 scores 154,858 against the WX 7100’s 40,148, a delta of -74.1% in favor of NVIDIA. In Geekbench Vulkan, the margin is even wider: 174,152 versus 39,683, a -77.2% delta. The WX 7100 wins zero tests in the head-to-head data. There is no compute or graphics workload in the provided results where the AMD card comes out ahead.

Where the WX 7100 does have a claim to relevance is in its average benchmark score relative to its nearest rivals. The card posts an average score of 40,063, placing it at the 82nd percentile of all GPUs. Its nearest rival, the AMD Radeon Pro 580, scores 40,318, which is only -0.6% different, meaning the WX 7100 is statistically on par with that card. The RTX 4070, by contrast, has an average score of 37,648, which sits at the 81st percentile. The RTX 4070’s nearest rivals include the NVIDIA Tesla P4 (37,628, +0.1%) and the AMD Radeon RX Vega 56 (37,507, +0.4%), showing it is closely matched with those older cards in aggregate. The WX 7100’s advantage is that it lands in the same performance band as the RTX 4070’s rivals, but the head-to-head numbers show the RTX 4070’s raw compute is in another league entirely.

Architecture Differences

The architectural divide is enormous. The WX 7100 uses the Ellesmere chip built on GCN 4.0, fabricated on a 14 nm process at GlobalFoundries. The RTX 4070 uses the AD104 chip on the Ada Lovelace architecture, built on a 5 nm process at TSMC. The transistor counts reflect this: the WX 7100 has 5,700 million transistors on a 232 mm² die, while the RTX 4070 packs 35,800 million transistors into a 294 mm² die. Transistor density jumps from 24.6M per mm² on the AMD card to 121.8M per mm² on the NVIDIA card.

The memory subsystems are completely different generations. The WX 7100 uses 8 GB of GDDR5 on a 256-bit bus, yielding 224.0 GB/s of bandwidth. The RTX 4070 uses 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s. Clock speeds are also far apart: the WX 7100 runs at 1188 MHz base and 1243 MHz boost, while the RTX 4070 runs at 1920 MHz base and 2475 MHz boost. The RTX 4070’s memory runs at 1313 MHz (21 Gbps effective) versus the WX 7100’s 1750 MHz (7 Gbps effective).

Feature support differs sharply. The RTX 4070 has 46 ray-tracing cores and 184 tensor cores, which the WX 7100 lacks entirely. The WX 7100 has 2304 shading units, 144 TMUs, and 32 ROPs, while the RTX 4070 has 5888 shading units, 184 TMUs, and 64 ROPs. The API support also diverges: the WX 7100 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, while the RTX 4070 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 4070 also uses PCIe 4.0 x16, whereas the WX 7100 is limited to PCIe 3.0 x16.

Head-to-Head Benchmarks

The only two direct benchmarks available are Geekbench OpenCL and Geekbench Vulkan, and the RTX 4070 wins both by crushing margins. In OpenCL, the RTX 4070 scores 154,858 versus the WX 7100’s 40,148. That is a 74.1% advantage for NVIDIA. In Vulkan, the RTX 4070 scores 174,152 against 39,683, a 77.2% lead. These are not close contests; the RTX 4070 is roughly four times faster in both tests.

The WX 7100’s best showing is in its own benchmark suite. Its Geekbench Metal score is 40,357, and its OpenCL and Vulkan scores are 40,148 and 39,683, respectively. Those numbers are internally consistent, but they are dwarfed by the RTX 4070’s OpenCL and Vulkan results. The RTX 4070 also has a Passmark G3D score of 26,927 and a Passmark GPU Compute score of 14,720, which are not directly comparable to the WX 7100’s Geekbench results but show strong overall performance. The RTX 4070’s average benchmark score of 37,648 is actually lower than the WX 7100’s 40,063, but that is because the averages are calculated across different test sets. The head-to-head data is what matters for a direct comparison, and it is a sweep for NVIDIA.

The Verdict

The data is unambiguous: pick the RTX 4070 for any modern workload that uses OpenCL or Vulkan. It is 74.1% faster in OpenCL and 77.2% faster in Vulkan than the WX 7100. The RTX 4070 also has a massive feature advantage with 46 RT cores, 184 tensor cores, and 12 GB of GDDR6X memory, none of which the WX 7100 can match. The WX 7100’s only saving grace is its average benchmark score of 40,063, which is higher than the RTX 4070’s 37,648, but that is a statistical artifact of different test suites. In any direct comparison, the RTX 4070 wins.

The WX 7100 is a legacy part. Its GCN 4.0 architecture and 14 nm process are outdated, and its 8 GB of GDDR5 is a bottleneck. The RTX 4070 is the practical choice for anyone needing raw compute or gaming performance. The WX 7100 might still be relevant for a niche user running legacy software that relies on specific GCN features, but the benchmark results do not support that conclusion. The head-to-head data says it all: the RTX 4070 is the faster card, period.
