A: The RTX 5090 Mobile has a TDP of 95 W despite delivering roughly 5.5 times the FP32 throughput. The WX 7100 has a 130 W TDP and requires a 300 W suggested PSU plus a 6-pin power connector, while the RTX 5090 Mobile needs no external power connectors.

Q: What is the production status of each card?

A: The RTX 5090 Mobile is listed as Active with a release date of 2025-03-26. The WX 7100 is End-of-life, having been released on 2016-11-09, with its successor being the Radeon Pro Vega.

Architecture Differences

The architectural gap between these two GPUs is massive. The RTX 5090 Mobile is built on NVIDIA's Blackwell 2.0 architecture using the GB203 chip, manufactured on a 5 nm process at TSMC. The WX 7100 uses AMD's GCN 4.0 architecture with the Ellesmere chip, fabricated on a 14 nm process at GlobalFoundries. This process difference alone — 5 nm versus 14 nm — explains much of the efficiency and density disparity.

Transistor counts tell the story starkly: the RTX 5090 Mobile packs 45,600 million transistors on a 378 mm² die, yielding a density of 120.6 million transistors per square millimeter. The WX 7100 has just 5,700 million transistors on a 232 mm² die, with a density of 24.6 million per square millimeter. That is an 8x difference in raw transistor count and nearly a 5x difference in density.

The compute resources are equally lopsided. The RTX 5090 Mobile features 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. The WX 7100 has 2,304 shading units, 144 TMUs, and 32 ROPs, with no RT cores or tensor cores at all. The RTX 5090 Mobile also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the WX 7100 is limited to DirectX 12 (12_0) and Vulkan 1.3.

Clock behavior also differs. The RTX 5090 Mobile runs at a 990 MHz base and 1515 MHz boost, while the WX 7100 has a higher base of 1188 MHz and boost of 1243 MHz. Despite the lower clocks, the RTX 5090 Mobile achieves a pixel rate of 169.7 GPixel/s and texture rate of 496.9 GTexel/s, versus 39.78 GPixel/s and 179.0 GTexel/s for the WX 7100.

The Verdict

For anyone choosing between these two, the data is unambiguous. The RTX 5090 Mobile is categorically superior in every measurable benchmark, with a 402.7% lead in OpenCL and 400% lead in Vulkan. The WX 7100's only advantage is its single-slot form factor and 4x DisplayPort 1.4a outputs, making it suitable for specific workstation configurations where those physical attributes matter.

The RTX 5090 Mobile should be the pick for any workload involving modern APIs, ray tracing, or tensor operations — the latter two being entirely absent from the WX 7100. Its 24 GB of GDDR7 memory and 896.0 GB/s bandwidth dwarf the WX 7100's 8 GB GDDR5 at 224.0 GB/s, making it the clear choice for large datasets or high-resolution textures.

The WX 7100 remains relevant only for legacy applications or scenarios where its 130 W TDP and single-slot design fit a specific chassis constraint. However, given its End-of-life status and the RTX 5090 Mobile's Active production status, the older card's utility is limited to already-deployed systems. The RTX 5090 Mobile also offers a higher transistor density and more modern feature set, including DirectX 12 Ultimate support.

Head-to-Head Benchmarks

The head-to-head data includes two tests, and the RTX 5090 Mobile wins both decisively. In Geekbench OpenCL, the RTX 5090 Mobile scores 201,834 against the WX 7100's 40,148, a delta of 402.7%. In Geekbench Vulkan, the margin is nearly identical: 198,405 versus 39,683, a 400% difference.

These results align with the theoretical specifications. The RTX 5090 Mobile's FP32 throughput of 31.80 TFLOPS is 5.55 times the WX 7100's 5.728 TFLOPS, which roughly matches the benchmark deltas when accounting for API overhead and driver efficiencies. The RTX 5090 Mobile's memory bandwidth of 896.0 GB/s is exactly four times the WX 7100's 224.0 GB/s, and its 24 GB capacity is triple the older card's 8 GB.

Looking at the nearest rivals for context, the RTX 5090 Mobile's average score of 45,152 places it just 0.5% below the Radeon Pro 5500 XT (45,384) and 0.8% above the RTX 4070 Ti (44,795). The WX 7100's average of 40,063 puts it 0.6% below the Radeon Pro 580 (40,318) and 1.3% above both the RTX A500 Mobile (39,568) and Radeon Pro 575 (39,555).

The RTX 5090 Mobile also holds a significant percentile advantage in the broader GPU landscape, sitting at the 84th percentile versus the WX 7100's 82nd. While both are above average, the RTX 5090 Mobile achieves this with a 95 W TDP versus the WX 7100's 130 W — a 36.8% power reduction in favor of the newer card. The RTX 5090 Mobile's PCIe 5.0 x16 interface further separates it from the WX 7100's PCIe 3.0 x16, enabling faster data transfer in systems that support the newer standard.
