AMD Radeon Pro WX 9100 vs NVIDIA RTX A1000 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive victory for the AMD Radeon Pro WX 9100 in every shared benchmark. In Geekbench OpenCL, the AMD card scores 66,605 against the NVIDIA RTX A1000 Mobile’s 48,703, a 36.8% advantage. That is not a marginal lead; it is a substantial gap that places the two cards in completely different performance tiers. The Vulkan result narrows the margin but still favors AMD clearly: 54,711 versus 46,782, a 16.9% difference. Across the two tests where both GPUs have recorded scores, the AMD card wins both, giving it a 2-0 head-to-head record.

What makes these numbers more meaningful is how they translate into percentile rankings. The AMD Radeon Pro WX 9100 sits at the 89th percentile among all GPUs in the database, while the NVIDIA RTX A1000 Mobile lands at the 85th percentile. That four-point gap in percentile ranking reflects a real separation in overall compute capability, not just a single favorable workload. The OpenCL result is particularly telling: a 36.8% delta is the kind of margin that shows up as dramatically longer render times or simulation waits on the NVIDIA side. For users whose workflows lean heavily on OpenCL acceleration, the choice is unambiguous.

The Vulkan score tells a slightly different story. At 16.9% apart, the two cards are closer, and the NVIDIA part shows it can close some of the gap in graphics-oriented APIs. Still, the AMD card remains ahead, and the advantage is consistent across both API environments. There is no benchmark in the shared dataset where the NVIDIA RTX A1000 Mobile pulls ahead. The data does not support any scenario where the mobile GPU outperforms the workstation card in raw compute throughput.

Looking at the nearest rivals for each card provides additional context. The AMD Radeon Pro WX 9100’s average benchmark score of 64,212 places it just 0.6% ahead of the NVIDIA CMP 30HX and the AMD Radeon RX 9060 XT LP, and 0.8% ahead of the AMD Radeon Pro Vega 56. That clustering suggests the WX 9100 is competitively positioned within its own performance neighborhood. The NVIDIA RTX A1000 Mobile, with an average score of 47,743, sits 1.5% behind the AMD Radeon RX 6800 XT but 2.2% ahead of the AMD Radeon RX 6550M and 2.4% ahead of the Intel Arc A530M. These delta values show that the RTX A1000 Mobile is not a weak performer in absolute terms; it is simply outclassed by the older, larger AMD workstation card.

Architecture Differences

The two GPUs come from fundamentally different design generations. The AMD Radeon Pro WX 9100 uses the Vega 10 chip built on GCN 5.0 architecture, fabricated on a 14 nm process at GlobalFoundries. That process node is comparatively old, but the chip is physically massive: 12,500 million transistors on a 495 mm² die. The transistor density works out to 25.3 million transistors per square millimeter, a modest figure by modern standards. In contrast, the NVIDIA RTX A1000 Mobile uses the GA107 chip on Ampere architecture, built on Samsung’s 8 nm process. It packs 8,700 million transistors onto a 200 mm² die, achieving a much higher density of 43.5 million transistors per square millimeter. That density advantage reflects the newer fabrication technology, but the AMD chip’s sheer size gives it a raw resource advantage.

The compute resources differ sharply. The AMD card fields 4,096 shading units, 256 texture mapping units, and 64 render output units. The NVIDIA card has 2,048 shading units, 64 TMUs, and 32 ROPs. In every category, the AMD card has double the execution resources. That explains the large FP32 throughput gap: the AMD card delivers 12.29 TFLOPS, while the NVIDIA card manages 4.669 TFLOPS. The AMD card also has a significant FP16 advantage, offering 24.58 TFLOPS with a 2:1 ratio, whereas the NVIDIA card provides 4.669 TFLOPS with a 1:1 ratio. For workloads that can exploit FP16, the AMD card is over five times faster on paper.

Memory architecture is another major differentiator. The AMD Radeon Pro WX 9100 uses 16 GB of HBM2 on a 2048-bit bus, delivering 483.8 GB/s of bandwidth. The NVIDIA RTX A1000 Mobile has 4 GB of GDDR6 on a 128-bit bus, providing 176.0 GB/s. That is a 2.75 times bandwidth advantage for AMD, which matters enormously for memory-bound compute tasks. The NVIDIA card does include dedicated hardware that AMD lacks: 16 ray tracing cores and 64 tensor cores. These features enable real-time ray tracing and AI acceleration, capabilities the Vega-based AMD card simply does not offer.

The API support also tells a generational story. The NVIDIA card supports DirectX 12 Ultimate (12_2), while the AMD card only reaches DirectX 12 (12_1). Both cards support OpenGL 4.6, but the NVIDIA card supports Vulkan 1.4 versus AMD’s Vulkan 1.3. The NVIDIA card’s newer architecture and feature set make it more future-proof for graphics workloads that leverage ray tracing, mesh shaders, or variable rate shading.

Specification Differences

The two cards differ across nearly every specification category. Clock speeds: the AMD card runs at 1200 MHz base and 1500 MHz boost, while the NVIDIA card runs at 630 MHz base and 1140 MHz boost. That is a substantial clock advantage for AMD, driven by its larger power budget. Memory speed also differs: AMD’s HBM2 runs at 945 MHz with 1890 Mbps effective, while NVIDIA’s GDDR6 runs at 1375 MHz with 11 Gbps effective. The effective data rate favors NVIDIA, but the bus width and total bandwidth favor AMD overwhelmingly.

Power consumption is a critical differentiator. The AMD Radeon Pro WX 9100 has a 230 W TDP and requires a 550 W suggested PSU with 1x 6-pin and 1x 8-pin power connectors. The NVIDIA RTX A1000 Mobile has a 60 W TDP, no power connectors, and no suggested PSU requirement. This is a 170 W difference, which translates directly into thermal and system integration implications. The AMD card is dual-slot and measures 267 mm in length and 111 mm in height. The NVIDIA card is an IGP (integrated graphics processor) form factor with no listed dimensions, designed for portable devices.

The bus interface also differs: AMD uses PCIe 3.0 x16, while NVIDIA uses PCIe 4.0 x8. The newer PCIe standard on the NVIDIA side provides comparable bandwidth with fewer lanes, but the AMD card’s full x16 allocation on PCIe 3.0 remains sufficient for most workloads. Display outputs are another clear separation: the AMD card offers 6x mini-DisplayPort 1.4a, while the NVIDIA card’s outputs are listed as portable device dependent, meaning they vary by laptop implementation.

Memory size differences are stark: 16 GB versus 4 GB. That fourfold capacity advantage for AMD matters for large datasets, high-resolution textures, and multi-application workflows. The NVIDIA card’s 4 GB is limiting for modern professional workloads. Production status for both is end-of-life, but the release dates differ: the AMD card launched on July 9, 2017, while the NVIDIA card launched on March 29, 2022, nearly five years later. The AMD card has a recorded launch MSRP of 1,599 USD; the NVIDIA card has no recorded launch MSRP.

The Verdict

The benchmark data makes the choice straightforward for compute-heavy professional workloads: the AMD Radeon Pro WX 9100 is the faster card. It wins both shared benchmarks, has a higher average score (64,212 versus 47,743), and ranks higher in the overall GPU percentile distribution (89th versus 85th). For OpenCL-based rendering, simulation, or data processing, the 36.8% advantage is decisive. The Vulkan gap of 16.9% is smaller but still firmly in AMD’s favor.

However, the NVIDIA RTX A1000 Mobile is not without its own reasons for selection. Its 60 W TDP makes it suitable for portable workstations where power and thermal constraints dominate. The AMD card’s 230 W TDP requires a desktop chassis with substantial cooling and power delivery. The NVIDIA card also brings ray tracing cores and tensor cores, enabling AI acceleration and real-time ray tracing that the AMD card cannot perform. Its support for DirectX 12 Ultimate and Vulkan 1.4 makes it more modern from an API standpoint.

The data suggests a use-case split. Users who need maximum raw compute throughput, large memory capacity, and high bandwidth should select the AMD Radeon Pro WX 9100. Users who need portability, low power consumption, AI acceleration, or ray tracing capabilities should select the NVIDIA RTX A1000 Mobile. The performance difference is real and measurable, but the form factor difference is even more profound. These cards target different physical environments, and the right choice depends on whether the workload lives on a desktop workstation or a mobile system.
