AMD Radeon Pro 575 vs NVIDIA GeForce RTX 5090 Mobile Comparison

The data places the NVIDIA GeForce RTX 5090 Mobile and the AMD Radeon Pro 575 in entirely different performance strata, despite their similar overall percentile rankings. The RTX 5090 Mobile sits at the 84th percentile of all GPUs, while the Radeon Pro 575 sits at the 82nd, but this proximity is misleading; the NVIDIA part's average benchmark score of 45,152 is built on modern DirectX 12 and compute tests, whereas the AMD part's 39,555 average reflects a much older feature set. In the only two directly comparable head-to-head benchmarks, the RTX 5090 Mobile leads by margins of 483.4% and 423.8%, making the choice between them a matter of era and workload, not incremental performance.

The Verdict

The benchmark data points to a decisive recommendation: the NVIDIA GeForce RTX 5090 Mobile is the superior choice for virtually any modern workload, while the AMD Radeon Pro 575 should only be considered for legacy macOS-specific tasks where its Metal score of 46,192 is the only metric available. The RTX 5090 Mobile's Geekbench OpenCL score of 201,834 is 483.4% higher than the Radeon Pro 575's 34,596, and its Vulkan score of 198,405 is 423.8% higher than the AMD part's 37,878. These are not marginal wins; they represent a generational gulf in raw compute and graphics throughput. The Radeon Pro 575's only competitive data point is its Geekbench Metal score, which has no corresponding result for the NVIDIA part, meaning its sole advantage is confined to Apple's Metal API environment. For anyone running Windows, Linux, or Vulkan-based applications, the RTX 5090 Mobile is the only defensible pick. For a legacy Mac Pro or iMac requiring a Metal-optimized GPU, the Radeon Pro 575 remains functional, but its end-of-life production status and 2017 release date signal that it is a stopgap, not a solution.

Architecture Differences

The two GPUs come from different manufacturing eras and design philosophies. The NVIDIA GeForce RTX 5090 Mobile is built on the Blackwell 2.0 architecture using TSMC's 5 nm process, packing 45,600 million transistors into a 378 mm² die for a transistor density of 120.6 million per square millimeter. The AMD Radeon Pro 575 uses the older GCN 4.0 architecture on GlobalFoundries' 14 nm process, with just 5,700 million transistors on a 232 mm² die and a density of 24.6 million per square millimeter. This process advantage translates directly into the RTX 5090 Mobile's feature set: it includes 82 ray tracing cores and 328 tensor cores, while the Radeon Pro 575 has neither. The NVIDIA part also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the AMD part is limited to DirectX 12 (12_0) and Vulkan 1.3. Both support OpenGL 4.6. The RTX 5090 Mobile connects via PCIe 5.0 x16, while the Radeon Pro 575 uses PCIe 3.0 x16, and the memory systems are equally divergent: the NVIDIA part uses 24 GB of GDDR7 on a 256-bit bus, while the AMD part uses 4 GB of GDDR5 on the same bus width.

Where Each One Wins

The RTX 5090 Mobile wins in every category where both parts have comparable data. In Geekbench OpenCL, it scores 201,834 versus 34,596, a 483.4% advantage. In Geekbench Vulkan, it scores 198,405 versus 37,878, a 423.8% advantage. The RTX 5090 Mobile also has benchmark results across 3DMark Steel Nomad (5,871), Passmark G3D (30,034), Passmark GPU Compute (13,401), and multiple Passmark DirectX tests, while the Radeon Pro 575 has no results for any of these tests. The Radeon Pro 575's only win is the Geekbench Metal score of 46,192, which is not matched by any NVIDIA result in the data. This means the AMD part has a niche in Metal-accelerated applications, but outside of that API, it has no benchmark victories. The RTX 5090 Mobile's shading unit count of 10,496, TMU count of 328, and ROP count of 112 dwarf the Radeon Pro 575's 2,048 shaders, 128 TMUs, and 32 ROPs, and its FP32 throughput of 31.80 TFLOPS is roughly seven times the AMD part's 4.489 TFLOPS. Pixel rate and texture rate follow the same pattern: 169.7 GPixel/s and 496.9 GTexel/s for NVIDIA versus 35.07 GPixel/s and 140.3 GTexel/s for AMD.

Head-to-Head Benchmarks

The head-to-head data provides only two directly comparable tests, and both are landslide wins for the NVIDIA GeForce RTX 5090 Mobile. In Geekbench OpenCL, the NVIDIA part scores 201,834 against the AMD Radeon Pro 575's 34,596, yielding a delta of 483.4%. This is the larger of the two margins and reflects the NVIDIA part's 31.80 TFLOPS FP32 throughput, which is built on 10,496 shading units operating at a boost clock of 1,515 MHz. The AMD part's 2,048 shading units, with no listed boost clock, produce only 4.489 TFLOPS. In Geekbench Vulkan, the RTX 5090 Mobile scores 198,405 versus 37,878, a 423.8% delta. Vulkan performance benefits from the NVIDIA part's PCIe 5.0 x16 interface and its support for Vulkan 1.4, whereas the AMD part is limited to PCIe 3.0 x16 and Vulkan 1.3. The memory bandwidth difference also plays a role: the RTX 5090 Mobile's 896.0 GB/s is more than four times the Radeon Pro 575's 217.0 GB/s. The RTX 5090 Mobile's 82 ray tracing cores and 328 tensor cores have no equivalent in the AMD part, which explains why the NVIDIA part can sustain higher throughput in geometry-heavy and compute-heavy Vulkan workloads. The data shows no benchmark where the Radeon Pro 575 closes the gap to within even 10% of the NVIDIA part.

Memory capacity is 24 GB of GDDR7 for NVIDIA versus 4 GB of GDDR5 for AMD, with bandwidth of 896.0 GB/s versus 217.0 GB/s on the same 256-bit bus. Pixel rate is 169.7 GPixel/s versus 35.07 GPixel/s, and texture rate is 496.9 GTexel/s versus 140.3 GTexel/s. FP16 throughput mirrors FP32 at 31.80 TFLOPS for NVIDIA and 4.489 TFLOPS for AMD. The RTX 5090 Mobile has a TDP of 95 W and uses an IGP slot width with no power connectors; the Radeon Pro 575 has a 150 W TDP and uses an MXM Module slot width, also with no power connectors. The bus interface is PCIe 5.0 x16 for NVIDIA and PCIe 3.0 x16 for AMD. API support differs on DirectX (12 Ultimate 12_2 versus 12 12_0) and Vulkan (1.4 versus 1.3). The RTX 5090 Mobile was released on March 26, 2025, and is Active in production; the Radeon Pro 575 was released on June 4, 2017, and is End-of-life.
