AMD Radeon Pro WX 7100 vs NVIDIA RTX A6000 Comparison

# Head-to-Head Benchmarks

The NVIDIA RTX A6000 dominates the AMD Radeon Pro WX 7100 in every shared benchmark, with margins that are not incremental but generational. In Geekbench OpenCL, the A6000 scores 193,937 against the WX 7100’s 40,148, a 383.1% advantage. That is not a close contest; it is a complete mismatch in raw compute throughput. The Vulkan result tells the same story: 164,462 for the A6000 versus 39,683 for the WX 7100, a 314.4% lead. Both cards were tested on the same two APIs, and the A6000 won both without exception.

The scale of these deltas matters. A 383.1% delta in OpenCL means the A6000 delivers nearly five times the score of the WX 7100. For context, the A6000’s average benchmark score across all tests is 44,075, while the WX 7100 averages 40,063 — a difference of roughly 10% overall. Yet in the head-to-head tests, the gap explodes to over 300%. This indicates that the A6000’s advantage is not uniform but concentrated in compute-heavy workloads, which is exactly where workstation buyers should focus.

The WX 7100 has no wins in the head-to-head set. It does not even appear in the same performance class. The A6000’s nearest rivals, by average score, are the GeForce RTX 4090 Mobile (43,667, just 0.9% behind) and the GeForce RTX 4070 Ti (44,795, 1.6% ahead). The WX 7100’s nearest rivals include the Radeon Pro 580 (40,318, 0.6% behind) and the GeForce RTX 5070 (40,377, 0.8% behind). The A6000 sits in the upper echelon of all GPUs, ranking in the 84th percentile, while the WX 7100 ranks in the 82nd percentile. Despite the percentile similarity, the actual score gap in the shared tests is enormous, showing that percentile rankings can obscure massive absolute differences.

# Architecture Differences

The architectural gulf between these two cards explains the benchmark chasm. The A6000 uses the GA102 chip on NVIDIA’s Ampere architecture, fabricated on an 8 nm process at Samsung. The WX 7100 uses the Ellesmere chip on AMD’s GCN 4.0 architecture, built on a 14 nm process at GlobalFoundries. The node difference alone — 8 nm versus 14 nm — accounts for significant efficiency and density gains, but the transistor counts tell a more dramatic story. The A6000 packs 28,300 million transistors on a 628 mm² die, yielding a density of 45.1 million transistors per square millimeter. The WX 7100 has just 5,700 million transistors on a 232 mm² die, at 24.6 million per square millimeter. The A6000 has nearly five times the transistor count and nearly three times the die area.

Compute resources follow the same pattern. The A6000 features 10,752 shading units, 336 texture mapping units, and 112 ROPs. The WX 7100 has 2,304 shading units, 144 TMUs, and 32 ROPs. That is roughly 4.7 times more shading units and 3.5 times more ROPs on the A6000. The A6000 also brings dedicated hardware the WX 7100 lacks entirely: 84 ray tracing cores and 336 tensor cores. The WX 7100 has no RT cores and no tensor cores, meaning any ray-traced or AI-accelerated workload is either impossible or severely handicapped on the AMD card.

Clock speeds differ as well, though not as dramatically. The A6000 runs at a base of 1410 MHz and boosts to 1800 MHz, while the WX 7100 runs at 1188 MHz base and 1243 MHz boost. The A6000’s boost clock is 557 MHz higher, a 44.8% advantage in raw clock rate. Combined with the massive shading unit count, the FP32 throughput gap is stark: 38.71 TFLOPS for the A6000 versus 5.728 TFLOPS for the WX 7100. That is a 6.75x difference in single-precision floating-point performance. FP16 performance is identical to FP32 on both cards (1:1 ratio), so the same 6.75x gap applies to half-precision workloads.

Memory architecture is another differentiator. The A6000 offers 48 GB of GDDR6 on a 384-bit bus, delivering 768.0 GB/s of bandwidth. The WX 7100 has 8 GB of GDDR5 on a 256-bit bus, with 224.0 GB/s. The A6000 has six times the memory capacity and 3.4 times the bandwidth. Memory clocks are 2000 MHz (16 Gbps effective) on the A6000 versus 1750 MHz (7 Gbps effective) on the WX 7100. For large datasets, the A6000’s capacity and bandwidth are not just better; they are in a different category.

# The Verdict

The data is unambiguous: the NVIDIA RTX A6000 is the superior workstation GPU by every measurable benchmark and architectural metric. In the two shared tests — Geekbench OpenCL and Vulkan — the A6000 wins by 383.1% and 314.4%, respectively. It has more shading units, more memory, higher clocks, faster bandwidth, and dedicated RT and tensor cores. The WX 7100 does not win a single head-to-head test.

Who should pick the A6000? Anyone running compute-heavy professional workloads — simulation, rendering, machine learning, or large-scale data processing. The 48 GB memory capacity alone justifies the choice for datasets that exceed 8 GB, and the 768.0 GB/s bandwidth ensures that large data moves quickly. The 84 RT cores and 336 tensor cores make it suitable for ray-traced visualization and AI inference, neither of which the WX 7100 can accelerate.

Who should pick the WX 7100? Based strictly on the data, only a user with minimal compute requirements and a hard constraint on power or physical size. The WX 7100 is a single-slot card with a 130 W TDP and a 300 W suggested PSU, versus the A6000’s dual-slot footprint, 300 W TDP, and 700 W suggested PSU. If a system cannot accommodate a dual-slot card or a 700 W power supply, the WX 7100 is the only option. But for raw performance, the WX 7100 is not competitive. Its 82nd percentile ranking among all GPUs is respectable, but its average score of 40,063 is less than the A6000’s 44,075 — and in the tests that matter, the gap is over 300%.

The verdict is not close. The A6000 is a high-end workstation card from 2020; the WX 7100 is a mid-range card from 2016. The four-year gap in release dates is visible in every benchmark and every architectural specification. Choose the A6000 unless physical or power constraints rule it out.

# Where Each One Wins

NVIDIA RTX A6000 wins on: OpenCL compute (193,937 vs 40,148), Vulkan compute (164,462 vs 39,683), FP32 throughput (38.71 TFLOPS vs 5.728 TFLOPS), memory capacity (48 GB vs 8 GB), memory bandwidth (768.0 GB/s vs 224.0 GB/s), shading unit count (10,752 vs 2,304), pixel rate (201.6 GPixel/s vs 39.78 GPixel/s), texture rate (604.8 GTexel/s vs 179.0 GTexel/s), and dedicated RT/tensor cores (84 RT, 336 tensor vs none). Any workload that stresses compute, memory, or modern graphics features belongs on the A6000.

AMD Radeon Pro WX 7100 wins on: power efficiency and physical footprint. It has a 130 W TDP versus 300 W, a single-slot design versus dual-slot, and a 300 W suggested PSU versus 700 W. It also has a shorter length (241 mm vs 267 mm) and a lower launch MSRP (799 USD vs 4,649 USD). For systems with strict power budgets, limited internal space, or legacy PCIe 3.0 motherboards, the WX 7100 is the only viable choice. Its Vulkan support (1.3 vs 1.4) and DirectX 12 (12_0 vs 12_2) are also lower, but it still offers OpenGL 4.6 parity.

The use-case split is clear: the A6000 for performance-critical professional workloads, the WX 7100 for constrained environments where the A6000 physically cannot fit or draw power. In every benchmark where both were tested, the A6000 wins by at least 314.4%. The WX 7100’s only advantages are operational, not performance-related.
