AMD Radeon Pro WX 9100 vs NVIDIA GeForce RTX 4070 Ti Comparison

The Verdict

The data separates these two clearly. The NVIDIA GeForce RTX 4070 Ti is the faster card in every recorded head-to-head benchmark, and by a very wide margin. It wins both shared tests, with a 62.4% lead in Geekbench OpenCL and a 74.4% lead in Geekbench Vulkan. If you need raw compute performance and modern API support, the RTX 4070 Ti is the only choice between these two.

The AMD Radeon Pro WX 9100, however, holds a different position. Its average benchmark score of 64,212 places it in the 89th percentile of all GPUs, while the RTX 4070 Ti sits at the 84th percentile with an average of 44,795. That seems contradictory at first glance. The explanation is that the WX 9100 was tested in more legacy and compute-oriented workloads where its HBM2 memory and GCN architecture still perform respectably, while the RTX 4070 Ti was measured across a broader set of tests including DirectX 9 through 12 and Passmark G2D, which drag its average down. The recorded data shows the WX 9100 sits very close to the NVIDIA CMP 30HX (0.6% ahead) and the AMD Radeon RX 9060 XT LP (0.6% ahead), making it a mid-pack performer in its own benchmark cohort.

For practical purposes: pick the RTX 4070 Ti if you want the highest compute scores, modern DirectX 12 Ultimate support, and a card that wins both head-to-head tests decisively. Pick the WX 9100 only if you specifically need 16 GB of HBM2 memory and six mini-DisplayPort outputs for professional multi-display setups, and you accept that its compute performance trails the RTX 4070 Ti by over 60% in the shared workloads.

Architecture Differences

The two cards come from completely different design eras and philosophies. The WX 9100 uses AMD's Vega 10 chip on the GCN 5.0 architecture, built on a 14 nm process at GlobalFoundries. It packs 12,500 million transistors on a 495 mm² die, giving a transistor density of 25.3 million per mm². The RTX 4070 Ti uses NVIDIA's AD104 chip on the Ada Lovelace architecture, built on a 5 nm process at TSMC. It crams 35,800 million transistors into a much smaller 294 mm² die, achieving a density of 121.8 million per mm². That is nearly five times the transistor density, which explains how NVIDIA gets so much more performance from a physically smaller chip.

The memory subsystems are fundamentally different. The WX 9100 uses 16 GB of HBM2 on a 2048-bit bus, delivering 483.8 GB/s of bandwidth. The RTX 4070 Ti uses 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s. The RTX 4070 Ti actually edges out the WX 9100 in raw bandwidth despite having a much narrower bus, because GDDR6X runs at 21 Gbps effective versus the HBM2's 1890 Mbps effective. The WX 9100's HBM2 advantage is capacity, not speed: 16 GB versus 12 GB.

Shader resources also differ sharply. The WX 9100 has 4096 shading units, 256 TMUs, and 64 ROPs. The RTX 4070 Ti has 7680 shading units, 240 TMUs, and 80 ROPs. NVIDIA has nearly double the shading units and more ROPs, though slightly fewer TMUs. The RTX 4070 Ti also adds 60 ray tracing cores and 240 tensor cores, hardware that the WX 9100 lacks entirely. The FP32 throughput tells the story: 12.29 TFLOPS for the WX 9100 versus 40.09 TFLOPS for the RTX 4070 Ti. The WX 9100's FP16 rate is 24.58 TFLOPS at a 2:1 ratio, while the RTX 4070 Ti does 40.09 TFLOPS at 1:1, meaning it does not sacrifice FP32 throughput when running FP16 workloads.

API support also separates them. The WX 9100 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The RTX 4070 Ti supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 4070 Ti is one step ahead on both DirectX and Vulkan.

Where Each One Wins

The head-to-head data shows only two shared benchmarks, and the RTX 4070 Ti wins both. In Geekbench OpenCL, the RTX 4070 Ti scores 176,953 against the WX 9100's 66,605, a 62.4% advantage. In Geekbench Vulkan, the RTX 4070 Ti scores 213,808 against 54,711, a 74.4% advantage. There are no recorded benchmark wins for the WX 9100 in the shared test set.

The WX 9100's case rests on non-performance factors and its own benchmark cohort. Its 16 GB of HBM2 memory is 4 GB more than the RTX 4070 Ti's 12 GB, which matters for very large datasets that exceed 12 GB. It has six mini-DisplayPort 1.4a outputs versus the RTX 4070 Ti's single HDMI 2.1 and three DisplayPort 1.4a outputs. For multi-monitor professional setups, the WX 9100 supports more displays natively. Its 230 W TDP is also lower than the RTX 4070 Ti's 285 W, and it only needs a 550 W suggested PSU versus 600 W for the RTX 4070 Ti.

The RTX 4070 Ti wins on every measurable performance axis in the shared tests. It also has a much stronger standalone benchmark profile. In Passmark G3D it scores 31,624, and in Passmark GPU Compute it scores 18,396. The WX 9100's standalone scores are 71,319 in Geekbench Metal and 66,605 in Geekbench OpenCL, but those are not directly comparable to the RTX 4070 Ti's test suite.

The practical split is simple: the RTX 4070 Ti is for anyone who needs maximum compute throughput, modern API features, and ray tracing hardware. The WX 9100 is for legacy professional workflows that need 16 GB of HBM2, six display outputs, and lower power draw.

Head-to-Head Benchmarks

The recorded head-to-head data is brief but conclusive. Only two tests were run on both cards, and the RTX 4070 Ti dominates both.

Geekbench OpenCL: the RTX 4070 Ti scores 176,953, while the WX 9100 scores 66,605. That is a 62.4% delta in favor of NVIDIA. This is a compute-oriented workload that stresses raw FP32 throughput and memory bandwidth. The RTX 4070 Ti's 40.09 TFLOPS of FP32 performance versus the WX 9100's 12.29 TFLOPS explains the gap. The RTX 4070 Ti also has 7680 shading units versus 4096, nearly double the shader count.

Geekbench Vulkan: the RTX 4070 Ti scores 213,808, while the WX 9100 scores 54,711. The delta is 74.4%, even larger than the OpenCL gap. Vulkan workloads tend to favor modern architectures with better driver optimization and hardware scheduling. The RTX 4070 Ti supports Vulkan 1.4, while the WX 9100 is limited to Vulkan 1.3. The RTX 4070 Ti's higher boost clock of 2610 MHz versus 1500 MHz also contributes, giving it a 1110 MHz advantage at peak.

The RTX 4070 Ti also shows strong standalone results that put its performance in context. Its Passmark G3D score is 31,624, and its Passmark GPU Compute score is 18,396. The WX 9100's best standalone result is 71,319 in Geekbench Metal, which is not a test the RTX 4070 Ti was not tested in. None of these are directly comparable across the two cards, but they show each card's strengths within its own test suite.

In terms of nearest rivals, the WX 9100 is essentially tied with the NVIDIA CMP 30HX (0.6% ahead), the AMD Radeon RX 9060 XT LP (0.6% ahead), and the AMD Radeon RX 7600M (0.7% ahead). The RTX 4070 Ti's nearest rivals include the NVIDIA GeForce RTX 5090 Mobile (0.8% behind), the AMD Radeon Pro 5500 XT (1.3% behind), and the NVIDIA RTX A6000 (1.6% ahead). These groupings show that the WX 9100 competes in a much lower performance tier than the RTX 4070 Ti, despite its higher percentile ranking.

Specification Differences

The two cards differ in nearly every major specification category. Here are the fields where they diverge:
