AMD Radeon Pro WX 7100 vs AMD Radeon RX 6900 XT Comparison

The Verdict

The data is unambiguous: the AMD Radeon RX 6900 XT is in a completely different performance class than the AMD Radeon Pro WX 7100. Across every shared benchmark, the RX 6900 XT wins decisively, with deltas ranging from 274.3% to 367.5%. The average benchmark score of 50,951 for the RX 6900 XT versus 40,063 for the Pro WX 7100 places them 27.2% apart overall. The Pro WX 7100, however, still holds a respectable 82nd percentile among all GPUs, meaning it is not a weak card, just an older one. For any workload where compute throughput matters, the RX 6900 XT is the only rational choice from this pairing.

The RX 6900 XT should be selected by anyone running modern DirectX 12 Ultimate workloads, Vulkan applications, or heavy compute tasks. Its 86th percentile ranking and scores like 187,673 in Geekbench OpenCL make it a strong performer. The Pro WX 7100, in contrast, is a single-slot, 130 W part from 2016. Its 82nd percentile is respectable, but its best recorded score is 40,357 in Geekbench Metal. That is less than a quarter of the RX 6900 XT's Metal score. For users with legacy software that prefers GCN 4.0 characteristics, or those who need a single-slot card with four DisplayPort outputs, the Pro WX 7100 remains a functional option, but it is not a performance competitor.

Head-to-Head Benchmarks

The three recorded head-to-head tests all use Geekbench, and all three are won by the RX 6900 XT. The largest margin is in OpenCL: the RX 6900 XT scores 187,673 against 40,148, a delta of 367.5%. That is a 4.7x advantage in raw compute throughput. The Metal test shows a 338.6% lead (177,021 vs 40,357), and Vulkan shows a 274.3% lead (148,525 vs 39,683). Every single recorded benchmark is a win for the RX 6900 XT.

The data also reveals that the Pro WX 7100 is internally consistent. Its three scores are very close: 40,357 (Metal), 40,148 (OpenCL), and 39,683 (Vulkan). That suggests the card is not bottlenecked by API-specific features but rather by its underlying hardware. The RX 6900 XT's scores spread more: 187,673 in OpenCL, 177,021 in Metal, and 148,525 in Vulkan. The Vulkan result is the RX 6900 XT's smallest win, but still a 274.3% lead. This indicates that Vulkan workloads narrow the gap slightly, but the RX 6900 XT's hardware advantage is overwhelming in every scenario.

The average benchmark scores confirm the trend. The RX 6900 XT averages 50,951, which is 27.2% higher than the Pro WX 7100's 40,063. The nearest rivals for the RX 6900 XT are the NVIDIA CMP 50HX (51,790, delta -1.6%), AMD Radeon RX Vega 64 (50,001, delta +1.9%), NVIDIA GeForce RTX 5070 Ti (49,957, delta +2%), and Intel Arc A550M (49,737, delta +2.4%). That places the RX 6900 XT in a tight pack with those cards. The Pro WX 7100's rivals are much closer: AMD Radeon Pro 580 (40,318, delta -0.6%), NVIDIA GeForce RTX 5070 (40,377, delta -0.8%), NVIDIA RTX A500 Mobile (39,568, delta +1.3%), and AMD Radeon Pro 575 (39,555, delta +1.3%). The Pro WX 7100 is within 1.3% of its nearest rivals, meaning it is a mid-pack performer in its own class.

Where Each One Wins

The RX 6900 XT wins every single benchmark in the database. It is unequivocally the better performer for all recorded workloads. Its 23.04 TFLOPS FP32 and 46.08 TFLOPS FP16 make it a compute monster, and its 80 ray tracing cores provide hardware acceleration that the Pro WX 7100 lacks entirely. The RX 6900 XT is the clear choice for any application that uses Metal, OpenCL, or Vulkan, as shown by its 274.3% to 367.5% leads. It also has 16 GB of memory versus 8 GB, and double the memory bandwidth (512.0 GB/s vs 224.0 GB/s), making it suitable for larger datasets and higher resolutions.

The Pro WX 7100's wins are not in performance but in physical attributes. It is a single-slot card, whereas the RX 6900 XT is triple-slot. It draws 130 W compared to 300 W, and requires only a 300 W PSU versus 700 W. It uses a single 6-pin power connector, while the RX 6900 XT needs two 8-pin connectors. The Pro WX 7100 is also shorter and has four DisplayPort outputs, which is useful for multi-display configurations. Its 14 nm process and GCN 4.0 architecture may be more compatible with older software that predates RDNA 2.0. For users with strict space, power, or display-count constraints, the Pro WX 7100 is the pragmatic pick. For anyone who wants the fastest benchmarks, the RX 6900 XT is the only option.
