AMD Radeon Pro WX 9100 vs AMD Radeon RX 9070 GRE Comparison

AMD Radeon Pro WX 9100 vs AMD Radeon RX 9070 GRE is a study in generational contrast. The data shows two very different AMD GPUs separated by nearly eight years of architectural evolution. The WX 9100 is an end-of-life workstation product built on a 14 nm process, while the RX 9070 GRE is an active consumer card on a 4 nm node. Their average benchmark scores are surprisingly close, yet their individual strengths and design philosophies could not be more distinct.

Head-to-Head Benchmarks

The only direct benchmark comparison available between these two cards is the Geekbench OpenCL test, and the result is decisive. The AMD Radeon RX 9070 GRE scores 109,309, while the AMD Radeon Pro WX 9100 trails at 66,605. That represents a 39.1% delta in favor of the newer card, which is a substantial margin in raw compute performance. The RX 9070 GRE is not just faster; it is nearly two-thirds again as fast in this specific workload.

However, the broader picture is more nuanced. The WX 9100 holds a higher overall percentile ranking, sitting at the 89th percentile of all GPUs, compared to the RX 9070 GRE’s 87th percentile. Its average benchmark score across all tests is 64,212, which is notably higher than the RX 9070 GRE’s average of 57,367. This discrepancy is fascinating — the older card wins on aggregate metrics, but loses badly on the one test where they directly intersect.

The nearest rivals for each card help contextualize their standings. The WX 9100’s closest competitor is the NVIDIA CMP 30HX, which scores 63,842, a mere 0.6% difference. The AMD Radeon RX 9060 XT LP and AMD Radeon RX 7600M are similarly close, with deltas of 0.6% and 0.7% respectively. The RX 9070 GRE, by contrast, sits near the Intel Arc A580 (57,756, a -0.7% delta) and the AMD Radeon RX 5600 OEM (58,085, -1.2%). The data suggests the RX 9070 GRE’s average score is dragged down by tests that do not favor its architecture, while the WX 9100 benefits from a more consistent baseline across various workloads.

Architecture Differences

The architectural gap here is immense. The WX 9100 uses the Vega 10 chip built on GCN 5.0 architecture, produced on a 14 nm process at GlobalFoundries. It packs 12,500 million transistors on a 495 mm² die, yielding a transistor density of 25.3 million per mm². The RX 9070 GRE, in contrast, uses the Navi 48 chip with RDNA 4.0 architecture, fabricated by TSMC on a 4 nm node. It contains 53,900 million transistors on a smaller 357 mm² die, achieving a density of 151.0 million per mm² — nearly six times the density of the older chip.

The memory subsystems are equally divergent. The WX 9100 uses 16 GB of HBM2 with a 2048-bit bus, providing 483.8 GB/s of bandwidth. The RX 9070 GRE uses 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. Despite the newer card having less memory and a narrower bus, the bandwidth gap is modest at just over 10%. The RX 9070 GRE compensates with much higher clocks, boosting to 2790 MHz versus the WX 9100’s 1500 MHz boost.

Compute resources also differ significantly. The WX 9100 has 4096 shading units, 256 TMUs, and 64 ROPs. The RX 9070 GRE has fewer shading units (3072) and TMUs (192), but more ROPs (96). Crucially, the RX 9070 GRE introduces 48 ray tracing cores, a feature entirely absent from the older card. The FP32 throughput tells the story of architectural efficiency: the WX 9100 delivers 12.29 TFLOPS, while the RX 9070 GRE delivers 34.28 TFLOPS — nearly triple the raw floating-point performance.

Where Each One Wins

The RX 9070 GRE wins decisively in raw compute and modern API support. Its 34.28 TFLOPS FP32 performance, combined with DirectX 12 Ultimate (12_2) and Vulkan 1.4 support, makes it the clear choice for modern gaming and compute workloads that leverage ray tracing or the latest graphics features. The 267.8 GPixel/s pixel rate and 535.7 GTexel/s texture rate dwarf the WX 9100’s 96.00 GPixel/s and 384.0 GTexel/s, indicating superior fill-rate performance in rasterization-heavy tasks.

The WX 9100, however, wins in memory capacity and aggregate benchmark consistency. Its 16 GB of HBM2 memory with 483.8 GB/s bandwidth gives it an edge in capacity-sensitive workloads, such as large dataset processing or high-resolution texture streaming. Its higher percentile ranking (89 vs 87) and superior average benchmark score (64,212 vs 57,367) suggest it performs more uniformly across a wider range of applications. The WX 9100 also supports six mini-DisplayPort 1.4a outputs, which is a clear advantage for multi-display workstation setups.

For legacy API compatibility, the WX 9100 supports DirectX 12 (12_1) and Vulkan 1.3, while the RX 9070 GRE supports DirectX 12 Ultimate and Vulkan 1.4. The newer card is strictly ahead in API versions, but the WX 9100’s support is still relevant for older software.

Specification Differences

The specification sheet reveals stark contrasts. The process node differs dramatically: 14 nm (GlobalFoundries) versus 4 nm (TSMC). Transistor count jumps from 12,500 million to 53,900 million, and die size shrinks from 495 mm² to 357 mm². Clocks are vastly different — the WX 9100 runs at 1200 MHz base and 1500 MHz boost, while the RX 9070 GRE runs at 1420 MHz base, 2220 MHz game clock, and 2790 MHz boost.

Memory configurations differ in size (16 GB vs 12 GB), type (HBM2 vs GDDR6), bus width (2048-bit vs 192-bit), and bandwidth (483.8 GB/s vs 432.0 GB/s). The shading unit count is higher on the WX 9100 (4096 vs 3072), as are TMUs (256 vs 192), but ROPs are higher on the RX 9070 GRE (96 vs 64). The RX 9070 GRE has 48 RT cores; the WX 9100 has none.

Power and connectivity differ too. Both are dual-slot cards with a 550 W suggested PSU, but the WX 9100 draws 230 W TDP with a 1x 6-pin + 1x 8-pin connector, while the RX 9070 GRE draws 220 W TDP with 2x 8-pin connectors. The bus interface is PCIe 3.0 x16 on the WX 9100 versus PCIe 5.0 x16 on the RX 9070 GRE. Display outputs favor the workstation card with six mini-DisplayPort 1.4a, versus one HDMI 2.1b and three DisplayPort 2.1a on the consumer card.

The Verdict

From the data, the AMD Radeon RX 9070 GRE is the superior choice for anyone prioritizing raw compute performance and modern features. Its 34.28 TFLOPS FP32 throughput, 48 RT cores, and DirectX 12 Ultimate support make it the obvious pick for gaming, ray tracing, and contemporary compute workloads. The 39.1% lead in Geekbench OpenCL underscores its compute advantage.

The AMD Radeon Pro WX 9100, however, remains relevant for specific workstation scenarios. Its 16 GB of HBM2 memory and 2048-bit bus offer a capacity and bandwidth profile that the RX 9070 GRE cannot match. The six mini-DisplayPort outputs and higher aggregate benchmark score suggest it handles a broader range of professional applications with greater consistency. Its 89th percentile ranking versus 87th indicates better all-around standing in the GPU landscape.

The choice hinges on workload. For single-application performance, especially compute-heavy tasks, the RX 9070 GRE is clearly ahead. For multi-display professional environments with large memory requirements and diverse software, the WX 9100’s strengths remain compelling despite its age. The RX 9070 GRE is the future-facing option; the WX 9100 is the proven, if older, workhorse.
