AMD Radeon PRO W7400 vs NVIDIA RTX A1000 Comparison

The Verdict

The database comparison places the NVIDIA RTX A1000 against the AMD Radeon PRO W7400 with a clear statistical gap. The RTX A1000 holds a 79th percentile ranking across all GPUs, while the W7400 sits at the 50th percentile. The RTX A1000 has recorded benchmark scores, with an average of 34207 across three tests, while the W7400 has no recorded benchmark scores in the database. This means the RTX A1000 is the only one of the two with measurable performance data, and its standing among its nearest rivals shows it clustering tightly with cards like the NVIDIA RTX A2000 12 GB, which is 0.2% ahead, and the NVIDIA TITAN V, which is 0.4% ahead. The W7400 cannot be placed relative to those same rivals because it lacks any average benchmark score. From the data available, the RTX A1000 is the card with proven performance credentials. The W7400 offers architectural advantages in process node and raw compute peaks, but without benchmark results, its real-world standing remains unquantified. For a buyer who needs verified performance, the RTX A1000 is the data-backed choice. The W7400 is the option for those prioritizing newer architecture traits, though the database cannot confirm its performance level.

Head-to-Head Benchmarks

The database has no direct head-to-head benchmark entries between the AMD Radeon PRO W7400 and the NVIDIA RTX A1000. The wins count for both cards is zero. However, the RTX A1000 has its own recorded benchmark results, which allow for a partial assessment. In 3DMark Steel Nomad DX12, the RTX A1000 scores 969. In Geekbench OpenCL, it scores 52078. In Geekbench Vulkan, it scores 49574. The average of these three scores is 34207.

The RTX A1000's nearest rivals in the database provide context. The NVIDIA RTX A2000 12 GB has an average score of 34154, which is 0.2% above the A1000. The AMD Radeon RX 560 XT has an average score of 34133, also 0.2% above. The AMD Radeon RX 480 has an average score of 33997, which is 0.6% above. The NVIDIA TITAN V has an average score of 34355, which is 0.4% below the A1000. These deltas are all within a narrow band, indicating the A1000 sits in a tightly contested performance cluster. The largest gap in either direction is the TITAN V at 0.4% below, meaning the A1000 is effectively at parity with all four rivals.

The W7400 has no benchmark scores, no average score, and no nearest rivals listed. The database therefore cannot produce a head-to-head comparison for the W7400 against the A1000 in any workload. The only quantitative performance data in this comparison belongs to the A1000.

Where Each One Wins

Based strictly on recorded data, the NVIDIA RTX A1000 wins in every measurable performance category because it is the only card with benchmark results. Its average score of 34207 places it at the 79th percentile of all GPUs. Its nearest rivals, all within 0.6% of its average score, confirm that it performs at a level comparable to established workstation and desktop cards. The A1000 also wins on memory bandwidth at 192.0 GB/s, shading units at 2304, and tensor cores at 72, which are present only on the NVIDIA card. Its boost clock of 1462 MHz is higher than the W7400's 1100 MHz.

The AMD Radeon PRO W7400 wins on architectural specification categories. It has the smaller 6 nm process node, higher transistor count at 13,300 million, higher transistor density at 65.2M per mm², more TMUs at 112, more ROPs at 64, more RT cores at 28, higher FP32 and FP16 compute at 7.885 TFLOPS, higher pixel rate at 70.40 GPixel/s, and higher texture rate at 123.2 GTexel/s. It also has a newer DisplayPort version, 2.1, versus the A1000's 1.4a. The W7400's TDP is 55 W versus 50 W, a small difference. The W7400 was released later, on 2025-08-02, compared to the A1000 on 2024-04-15.

The use-case split follows the data. For anyone seeking verified benchmark performance, the A1000 is the only card with evidence. Its 79th percentile ranking and tight cluster around the RTX A2000 12 GB and TITAN V suggest it is a dependable performer in the database's workload samples. The W7400 presents a theoretical case based on newer architecture and higher raw throughput numbers, but the absence of benchmark scores means the database cannot confirm those specifications translate into measured wins. The W7400's higher FP32 and FP16 figures suggest potential in compute-heavy tasks, while its higher pixel and texture rates suggest potential in rasterization-heavy workloads, but those remain projections, not measurements.
