AMD Radeon Pro WX 9100 vs NVIDIA GeForce RTX 5070 Ti Comparison

The AMD Radeon Pro WX 9100 and NVIDIA GeForce RTX 5070 Ti represent two very different eras of GPU design, separated by roughly eight years of architectural evolution. The database records show the RTX 5070 Ti dominating in the two shared benchmark tests, but the WX 9100 still holds its own as a legacy workstation part with a unique memory configuration. This comparison examines what the measured scores reveal about performance, architecture, and suitability for different workloads.

Head-to-Head Benchmarks

The database contains two direct comparison points between these cards: Geekbench OpenCL and Geekbench Vulkan. In both tests, the NVIDIA GeForce RTX 5070 Ti wins decisively.

In Geekbench OpenCL, the RTX 5070 Ti scores 212,363 against the WX 9100’s 66,605. That is a delta of -68.6%, meaning the AMD card trails by more than two-thirds. The OpenCL test stresses raw compute throughput across the GPU, and the RTX 5070 Ti’s 43.94 TFLOPS FP32 output versus the WX 9100’s 12.29 TFLOPS explains much of the gap. The newer card delivers roughly 3.6 times the raw floating-point performance, and the benchmark reflects that scale of difference.

The Vulkan result is even more lopsided. The RTX 5070 Ti scores 225,122, while the WX 9100 manages 54,711. That is a delta of -75.7%. Vulkan workloads often favor newer architectures with better driver optimization and hardware feature support, and the RTX 5070 Ti’s Blackwell 2.0 design with 70 RT cores and 280 tensor cores gives it a structural advantage in modern rendering pipelines. The WX 9100 has no dedicated RT or tensor hardware, so it relies entirely on its GCN 5.0 shader array.

These two wins give the RTX 5070 Ti a clean 2-0 record in head-to-head tests. The WX 9100 has zero wins in the shared benchmark suite. However, the WX 9100’s average benchmark score across all recorded tests is 64,212, which places it in the 89th percentile of all GPUs in the database. The RTX 5070 Ti’s average score is 49,957, in the 86th percentile. This discrepancy arises because the two cards are tested under different benchmark sets: the WX 9100’s average includes only Geekbench Metal, OpenCL, and Vulkan scores, while the RTX 5070 Ti’s average pulls from a wider mix including 3DMark, Passmark, and Geekbench entries. The RTX 5070 Ti’s Passmark scores are notably low (192 in DirectX 10, 300 in DirectX 11, 127 in DirectX 12, 351 in DirectX 9), which drags its aggregate down despite the strong Geekbench numbers.

FAQ

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Radeon Pro WX 9100 uses GCN 5.0 architecture on a 14 nm process from GlobalFoundries. It packs 12,500 million transistors onto a 495 mm² die. The NVIDIA GeForce RTX 5070 Ti uses Blackwell 2.0 on a 5 nm TSMC node, with 45,600 million transistors on a smaller 378 mm² die. The newer process enables a transistor density of 120.6 million per square millimeter versus 25.3 million for the AMD part.

Shader organization differs significantly. The WX 9100 has 4,096 shading units, 256 texture mapping units, and 64 ROPs. The RTX 5070 Ti has 8,960 shading units, 280 TMUs, and 96 ROPs. The RTX 5070 Ti also adds dedicated hardware the WX 9100 lacks: 70 RT cores for ray tracing and 280 tensor cores for AI workloads. These specialized units allow the Blackwell architecture to handle tasks outside the traditional shader pipeline.

Memory architecture is another major divergence. The WX 9100 uses 16 GB of HBM2 on a 2048-bit bus, yielding 483.8 GB/s bandwidth. The RTX 5070 Ti also has 16 GB, but uses GDDR7 on a 256-bit bus, achieving 896.0 GB/s. The HBM2 approach gives the older card a very wide but slower interface, while the newer GDDR7 runs at higher effective speeds (28 Gbps versus 1890 Mbps effective for the WX 9100’s memory).

The process node difference also affects clock behavior. The WX 9100 runs at a 1200 MHz base and 1500 MHz boost. The RTX 5070 Ti runs at 2295 MHz base and 2452 MHz boost, nearly double the AMD card’s boost clock. This clock advantage, combined with more shaders, produces the large FP32 gap.

The Verdict

The benchmark data is unambiguous: the NVIDIA GeForce RTX 5070 Ti wins both shared head-to-head tests by massive margins. In OpenCL, it leads by 68.6%; in Vulkan, by 75.7%. Anyone prioritizing raw compute performance in these APIs should choose the RTX 5070 Ti without hesitation.

However, the WX 9100 is not without merit. Its average benchmark score of 64,212 exceeds the RTX 5070 Ti’s 49,957, and it sits in the 89th percentile versus the RTX 5070 Ti’s 86th. This is a quirk of the database’s test selection, but it indicates that the WX 9100 performs strongly in its native Geekbench Metal workload, where it scores 71,319. The RTX 5070 Ti has no Metal benchmark recorded, so cross-platform comparison is limited.

The WX 9100’s HBM2 memory with a 2048-bit bus offers a different bandwidth profile than the RTX 5070 Ti’s GDDR7. For workloads that favor extremely wide memory interfaces, the older AMD card may still be relevant. But the RTX 5070 Ti’s 896.0 GB/s bandwidth is nearly double, and its much higher clock speeds and shader counts make it the superior choice for modern rendering and compute.

The RTX 5070 Ti also brings features the WX 9100 cannot match: 70 RT cores, 280 tensor cores, DirectX 12 Ultimate support, Vulkan 1.4, and PCIe 5.0. These hardware capabilities enable ray-traced workloads and AI-accelerated tasks that the GCN 5.0 architecture simply cannot handle efficiently.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Ti wins in every scenario where the two cards share a benchmark test. It dominates OpenCL and Vulkan, and its architecture provides hardware support for ray tracing and tensor operations. For gaming, real-time rendering, AI inference, or any workload that can use Blackwell’s specialized cores, the RTX 5070 Ti is the clear choice. Its 43.94 TFLOPS FP32 and 896.0 GB/s bandwidth make it a high-throughput performer in compute-heavy applications.

The AMD Radeon Pro WX 9100 wins in the niche case of Metal API performance, where it scores 71,319 in Geekbench Metal. This is a macOS-oriented benchmark, and the WX 9100’s 89th percentile overall ranking suggests it remains competitive in certain legacy workstation contexts. Its HBM2 memory with 2048-bit bus width provides a wide data path that can benefit memory-bandwidth-sensitive applications that are not captured in the shared tests. For users running older software stacks that predate Blackwell, or those requiring six mini-DisplayPort outputs for multi-display setups, the WX 9100 offers a unique configuration.

The RTX 5070 Ti’s 2-0 head-to-head record, combined with its architectural advantages in RT and tensor hardware, makes it the recommended pick for most users. The WX 9100 remains a viable option only for specific legacy use cases where its Metal performance, wide HBM2 bus, or six-display output capability outweigh the substantial compute deficit. The data shows a generational leap rather than a close contest, with the newer NVIDIA card leading by margins of 68.6% to 75.7% in the tests they share.
