AMD Radeon Pro WX 7100 vs AMD Radeon RX 7900 GRE Comparison

# AMD Radeon Pro WX 7100 vs AMD Radeon RX 7900 GRE

The database places these two AMD offerings at opposite ends of the market spectrum. The Radeon Pro WX 7100 is a professional workstation card built on the older GCN architecture, while the Radeon RX 7900 GRE is a high-end consumer gaming part using the RDNA 3 architecture. The data shows a clear split: the RX 7900 GRE wins every recorded head-to-head benchmark, but the WX 7100 retains advantages in features and efficiency that matter for professional workflows.

Where Each One Wins

The recorded benchmark data is unambiguous. The Radeon RX 7900 GRE is the winner in both head-to-head tests. In the Geekbench OpenCL test, the RX 7900 GRE scores 175,758 against the WX 7100's 40,148, a 77.2% advantage. In the Vulkan test, the RX 7900 GRE scores 99,850 to the WX 7100's 39,683, a 60.3% lead. The WX 7100 does not win a single head-to-head benchmark in this database.

The RX 7900 GRE also sits higher in the overall percentile ranking, at the 77th percentile of all GPUs, while the WX 7100 sits at the 82nd percentile. This suggests the RX 7900 GRE is not only faster than the WX 7100, but also faster than most other GPUs in the database.

Architecture Differences

The two cards come from different generations of GPU architecture. The AMD Radeon Pro WX 7100 is based on the Ellesmere chip, using the GCN 4.0 architecture. It is built on a 14nm process at GlobalFoundries and contains 5,700 million transistors on a 232 mm² die. The RX 7900 GRE, codenamed Plum Bonito, uses the Navi 31 chip and the RDNA 3.0 architecture. It is manufactured on a 5nm node at TSMC, with 57,700 million transistors on a 529 mm² die.

The transistor density numbers tell a story of architectural evolution. The WX 7100 packs 24.6 million transistors per square millimeter, while the RX 7900 GRE packs 109.1 million per square millimeter. This is a massive generational leap in integration density, and it explains how the RX 7900 GRE can fit 5120 shading units, 320 texture mapping units, and 160 ROPs, compared to 2304, 144, and 32 on the WX 7100.

Clock speeds also favor the newer card. The RX 7900 GRE operates at a base clock of 1287 MHz with a boost of 2245 MHz. The WX 7100 has a base of 1188 MHz and a boost of 1243 MHz. Memory clocks are 2250 MHz versus 1750 MHz. The RX 7900 GRE also has 64 ray accelerators, a feature entirely absent from the WX 7100.

Head-to-Head Benchmarks

The database includes two direct comparisons between these cards, both in compute-style workloads. These tests stress raw shading throughput and compute capability.

In Geekbench OpenCL, the AMD Radeon RX 7900 GRE scores 175,758. The AMD Radeon Pro WX 7100 scores 40,148. This is a 77.2% deficit for the WX 7100. The RX 7900 GRE is the clear winner in this synthetic compute test.

The Geekbench Vulkan test shows a similar result. The RX 7900 GRE scores 99,850, while the WX 7100 scores 39,683. The RX 7900 GRE is 60.3% faster here. This benchmark is typically more representative of graphics-level performance, and the gap remains enormous.

These results indicate that the RX 7900 GRE is in a different performance class entirely. The WX 7100 is a workstation card designed for stability and qualified software, while the RX 7900 GRE is a gaming card with raw performance as its priority.

The memory configuration is a major differentiator. The RX 7900 GRE has double the capacity (16 GB versus 8 GB) and uses faster GDDR6 memory. It also has a 256-bit memory bus, same as the WX 7100, but with a 576.0 GB/s bandwidth versus 224.0 GB/s. This contributes to the massive performance difference in memory-heavy workloads.

The RX 7900 GRE also has more execution units: 5120 shading units, 320 TMUs, and 160 ROPs. These are more than double the WX 7100's 2304 shading units, 144 TMUs, and 32 ROPs. The compute rates are also much higher: 45.98 TFLOPS FP32 versus 5.728 TFLOPS.

Power and physical size also differ. The WX 7100 is a single-slot card with a 130 W TDP and one 6-pin power connector. The RX 7900 GRE is a dual-slot card with a 260 W TDP and two 8-pin power connectors. The suggested power supply is 300 W for the WX 7100 and 600 W for the RX 7900 GRE.

FAQ

Q: Which card is faster in the database benchmarks?

A: The AMD Radeon RX 7900 GRE wins every head-to-head. It leads by 77.2% in Geekbench OpenCL and by 60.3% in Geekbench Vulkan.

Q: What is the main reason for the performance gap?

A: The RX 7900 GRE is based on a much newer architecture (RDNA 3.0 vs GCN 4.0), a smaller process node (5nm vs 13nm), and has far more execution resources: 5120 shading units, 320 TMUs, and 160 ROPs versus 2304, 144, and 32. This allows for significantly higher shading rates and compute throughput.

Q: Does the WX 7100 have any advantages?

A: Yes. The data shows it is a single-slot card with a lower 130 W TDP, and its 4x DisplayPort 1.4a outputs are suited for professional multi-display workstations. It also uses only one 6-pin power connector on a 300 W recommended power supply.

Q: Are these cards in the same performance class?

A: No. The RX 7900 GRE is in the 77th percentile of all GPUs, while the WX 7100 is in the 82nd percentile. But the RX 7900 GRE wins in raw compute and is more modern in almost every specification.

The Verdict

The data is clear: the AMD Radeon RX 7900 GRE is the faster card in every benchmark record and has a decisive architectural advantage. It is the obvious choice for anyone purely looking for maximum raw performance, modern features, and the highest compute throughput.

The AMD Radeon Pro WX 7100 is a different type of product: a single-slot, 130 W professional card with four DisplayPort outputs, aimed at workstation environments where driver certification and multiple display support are more important than raw compute. Its older architecture and lower performance numbers put it in a different category.

So the final call from the data: for raw performance, the AMD Radeon RX 7900 GRE is the pick. For a single-slot professional workstation card with the lowest power and a different display output configuration, the AMD Radeon Pro WX 7100 is the relevant option; just do not expect it to keep pace with the RX 7900 GRE in compute-heavy benchmarks.
