AMD Radeon Pro WX 7100 vs NVIDIA GeForce RTX 4080 Mobile Comparison

The benchmark data positions the NVIDIA GeForce RTX 4080 Mobile as the decisive performance leader, with the AMD Radeon Pro WX 7100 falling far behind in raw compute output. The RTX 4080 Mobile wins both head-to-head tests by massive margins, while the WX 7100 counters with a lower power draw and a desktop-oriented form factor.

Head-to-Head Benchmarks

The RTX 4080 Mobile delivers a dominant performance in every measured workload. In the Geekbench OpenCL test, the NVIDIA GPU scores 159,575 against the AMD’s 40,148, representing a 74.8% advantage. The Vulkan result is similarly lopsided: the RTX 4080 Mobile posts 145,807 while the WX 7100 manages 39,683, a 72.8% lead for NVIDIA. These are not marginal victories; the RTX 4080 Mobile is roughly four times faster in both APIs.

The magnitude of this gap is unprecedented in typical desktop-vs-mobile comparisons. The WX 7100’s average benchmark score of 40,063 places it in the 82nd percentile of all GPUs, while the RTX 4080 Mobile’s average of 38,135 sits in the 81st percentile. However, that average for the RTX 4080 Mobile is dragged down by its Passmark scores—which include a 15,9575 OpenCL result but also a 157 DirectX 10 score and a 96 DirectX 12 score—while the AMD card has only three Geekbench results. When isolating the shared Geekbench workloads, the NVIDIA card’s superiority is absolute.

The RTX 4080 Mobile also shows strength in specialized DirectX tests, scoring 286 in DirectX 9 and 244 in DirectX 11, though these have no direct AMD counterpart in the data. Its Passmark G3D score of 24,926 and GPU compute score of 11,191 further illustrate its compute density, though again without a WX 7100 comparison point. The data is clear: for any application leveraging OpenCL or Vulkan, the RTX 4080 Mobile is the only rational choice between these two.

Architecture Differences

The two GPUs come from fundamentally different design eras. The AMD Radeon Pro WX 7100 uses the Ellesmere chip built on GCN 4.0 architecture, fabricated by GlobalFoundries on a 14 nm process. It contains 5,700 million transistors on a 232 mm² die, yielding a transistor density of 24.6 million per square millimeter. In contrast, the NVIDIA GeForce RTX 4080 Mobile uses the AD104 chip on Ada Lovelace architecture, manufactured by TSMC on a 5 nm process. This chip packs 35,800 million transistors into a 294 mm² die, achieving a density of 121.8 million per square millimeter—roughly five times denser than the AMD part.

The compute resources differ even more dramatically. The WX 7100 has 2,304 shading units, 144 texture mapping units, and 32 ROPs. The RTX 4080 Mobile has 7,424 shading units, 232 TMUs, and 80 ROPs. NVIDIA also adds 58 ray tracing cores and 232 tensor cores, features entirely absent from the AMD architecture. These hardware differences translate into raw throughput: the AMD card delivers 5.728 TFLOPS of FP32 and FP16 (1:1), while the NVIDIA card delivers 24.72 TFLOPS in both formats—a 4.3x advantage.

Memory subsystems reflect different priorities. The WX 7100 uses 8 GB of GDDR5 on a 256-bit bus, providing 224.0 GB/s of bandwidth. The RTX 4080 Mobile has 12 GB of GDDR6 on a 192-bit bus, but with a much higher 432.0 GB/s bandwidth thanks to faster memory clocks (18 Gbps effective versus 7 Gbps). The NVIDIA card’s memory bandwidth advantage is 1.9x despite a narrower bus.

Process node and transistor count also influence power characteristics. The WX 7100 has a 130 W TDP and requires a 6-pin power connector with a 300 W suggested PSU. The RTX 4080 Mobile is rated at 110 W, uses no external power connector (IGP form factor), and has no suggested PSU. The newer 5 nm process enables higher performance at lower power.

The Verdict

The data supports only one conclusion: the NVIDIA GeForce RTX 4080 Mobile is the superior GPU in every measured performance metric. It wins both head-to-head benchmarks with margins exceeding 72%, offers more than three times the shading units, and provides nearly double the memory bandwidth. The AMD Radeon Pro WX 7100’s advantages are limited to its desktop form factor (single-slot, 241 mm length), its four DisplayPort 1.4a outputs, and its lower 130 W TDP—though the RTX 4080 Mobile’s 110 W TDP is actually lower.

For any workload that benefits from OpenCL or Vulkan compute—which includes most professional rendering, simulation, and machine learning tasks—the RTX 4080 Mobile is the clear choice. The WX 7100’s 5.728 TFLOPS of FP32 performance cannot compete with the RTX 4080 Mobile’s 24.72 TFLOPS. The RTX 4080 Mobile also brings modern features like ray tracing cores and tensor cores that the WX 7100 lacks entirely.

The only scenario where the WX 7100 makes sense is if a user requires a desktop card with four DisplayPort outputs and a single-slot form factor, and does not need the performance headroom of the RTX 4080 Mobile. Given that the RTX 4080 Mobile is an IGP (integrated into a laptop), the comparison is somewhat unusual—the desktop AMD card cannot be installed in a notebook. For mobile users, the RTX 4080 Mobile is the only option, and it is overwhelmingly the better performer.

Where Each One Wins

NVIDIA GeForce RTX 4080 Mobile wins in: OpenCL performance (159,575 vs 40,148), Vulkan performance (145,807 vs 39,683), raw compute throughput (24.72 vs 5.728 TFLOPS), memory bandwidth (432.0 vs 224.0 GB/s), pixel fill rate (133.2 vs 39.78 GPixel/s), texture fill rate (386.3 vs 179.0 GTexel/s), ray tracing (58 RT cores vs none), tensor acceleration (232 tensor cores vs none), memory capacity (12 GB vs 8 GB), and power efficiency (110 W TDP for much higher performance).

AMD Radeon Pro WX 7100 wins in: Desktop form factor (single-slot, 241 mm length, 4x DisplayPort 1.4a), PCIe 3.0 compatibility (though the RTX 4080 Mobile supports PCIe 4.0), and a wider memory bus (256-bit vs 192-bit). It also has a higher transistor density per square millimeter of die area relative to its own process node, though the absolute density is far lower. The WX 7100’s only practical advantages are physical—it is a standalone card that can be installed in a desktop workstation with four display outputs, whereas the RTX 4080 Mobile is an integrated laptop component.

For desktop workstation users who need multiple DisplayPort outputs and a single-slot card, the WX 7100 serves a specific niche. For anyone prioritizing compute performance in OpenCL or Vulkan, the RTX 4080 Mobile is the definitive winner, with a 74.8% and 72.8% lead respectively. The RTX 4080 Mobile also offers newer API support (DirectX 12 Ultimate, Vulkan 1.4) and a more advanced 5 nm process that delivers higher performance at lower power.
