NVIDIA GeForce MX550 vs NVIDIA RTX PRO 4500 Blackwell Comparison

Where Each One Wins

The benchmark data splits these two GPUs into completely different performance classes. The NVIDIA RTX PRO 4500 Blackwell wins the only shared benchmark, Geekbench Vulkan, by a massive 583% margin. That single result tells most of the story: the RTX PRO 4500 is a workstation-class part designed for heavy compute and professional workloads, while the GeForce MX550 is a lightweight mobile chip for basic acceleration.

Looking at the overall averages, the RTX PRO 4500 sits at 31,532 average benchmark score, placing it in the 76th percentile of all GPUs. Its nearest rivals include the NVIDIA TITAN RTX (31,676, only 0.5% behind) and the Intel Arc Pro A30M (31,894, 1.1% ahead). This places it firmly in the upper-mid range of the database, competitive with older flagship cards. The MX550, by contrast, averages 26,421, which puts it in the 72nd percentile. Its closest competitors are the AMD Radeon 860M (26,401, 0.1% behind) and the NVIDIA GeForce RTX 5060 (26,331, 0.3% ahead). Despite the lower absolute scores, the MX550 still holds a respectable percentile ranking because the database includes many much weaker integrated and entry-level parts.

The RTX PRO 4500 has a full suite of benchmark results across multiple tests: 3DMark Steel Nomad DX12 scores 7,025, Passmark G3D scores 33,360, and Passmark GPU Compute scores 19,255. The MX550 only has two recorded benchmarks: Geekbench OpenCL at 20,372 and Geekbench Vulkan at 32,469. This missing data means the MX550 cannot be compared on DirectX or compute workloads directly, but the Vulkan result alone shows it is outclassed by the RTX PRO 4500 in graphics API performance.

For use-case selection, the data supports one clear split: the RTX PRO 4500 is for demanding professional tasks, large datasets, and high-resolution rendering. The MX550 is for basic laptop duties, light photo editing, and legacy software acceleration. There is no benchmark where the MX550 wins, so no workload in the recorded data favors it.

Architecture Differences

The two GPUs come from different architectural generations and process nodes. The RTX PRO 4500 uses the GB203 chip built on Blackwell 2.0 architecture, manufactured on a 5 nm process at TSMC. It packs 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6 million per square millimeter. The MX550 uses the TU117SB chip on Turing architecture, built on a 12 nm process also at TSMC. It has 4,700 million transistors on a 200 mm² die, with a density of 23.5 million per square millimeter. The RTX PRO 4500 has nearly ten times the transistors and almost double the die area, with a much denser design.

The memory subsystems are also radically different. The RTX PRO 4500 comes with 32 GB of GDDR7 memory on a 256-bit bus, providing 896.0 GB/s of bandwidth. The MX550 has 2 GB of GDDR6 on a 64-bit bus, yielding 96.00 GB/s. That is a 9.3x bandwidth advantage for the RTX PRO 4500, which matters enormously for large textures, ray tracing, and compute workloads.

Compute resources scale accordingly. The RTX PRO 4500 has 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. The MX550 has 1,024 shading units, 32 TMUs, and 16 ROPs, with no RT cores and no tensor cores. The RTX PRO 4500 delivers 50.53 TFLOPS of FP32 and FP16 (1:1), while the MX550 delivers 2.703 TFLOPS of both. Pixel rate is 269.6 GPixel/s versus 21.12 GPixel/s, and texture rate is 789.5 GTexel/s versus 42.24 GTexel/s.

The RTX PRO 4500 supports DirectX 12 Ultimate (12_2), while the MX550 only supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The RTX PRO 4500 uses PCIe 5.0 x16, while the MX550 uses PCIe 4.0 x8. The RTX PRO 4500 has four DisplayPort 2.1b outputs; the MX550 is portable device dependent. Power requirements are starkly different: the RTX PRO 4500 has a 200 W TDP with a 550 W suggested PSU and a dual-slot cooler, while the MX550 has a 25 W TDP, no power connectors, and is an IGP (integrated graphics package for laptops).

Head-to-Head Benchmarks

Only one shared benchmark exists in the database: Geekbench Vulkan. The RTX PRO 4500 scores 221,768, while the MX550 scores 32,469. The delta is 583% in favor of the RTX PRO 4500. That is not a marginal edge; it is a full order of magnitude gap. In practical terms, the RTX PRO 4500 delivers over six times the raw Vulkan performance of the MX550.

The MX550 does have its own Geekbench OpenCL score of 20,372, but the RTX PRO 4500 has no recorded OpenCL result, so no cross-comparison is possible there. Similarly, the RTX PRO 4500 has multiple Passmark scores (DirectX 9: 397, DirectX 10: 204, DirectX 11: 320, DirectX 12: 119, G2D: 1,336, G3D: 33,360, GPU Compute: 19,255) and a 3DMark Steel Nomad score of 7,025, but the MX550 lacks any of those entries. The recorded data therefore gives a one-dimensional comparison, but that dimension is decisive.

Given the architecture differences, the Vulkan result aligns with expectations. The RTX PRO 4500 has 10.25x more shading units, 10.25x more TMUs, 7x more ROPs, and 9.3x more memory bandwidth. The 583% delta in Vulkan underperforms what the raw hardware ratios suggest, likely due to driver overhead and the MX550 being a simpler architecture that scales differently in API-bound tests. Still, the conclusion is unambiguous: the RTX PRO 4500 dominates the shared workload.

The Verdict

The data points to a clear verdict: the NVIDIA RTX PRO 4500 Blackwell is the superior GPU in every measurable way within this comparison. It wins the only shared benchmark by 583%, has a higher average score (31,532 versus 26,421), a higher percentile ranking (76th versus 72nd), and a far more complete benchmark profile. The MX550 cannot compete on any recorded metric.

Who should pick the RTX PRO 4500? Anyone running professional applications that stress VRAM capacity, memory bandwidth, or compute throughput. The 32 GB GDDR7 pool and 896.0 GB/s bandwidth make it suitable for large scene rendering, AI inference, and multi-display setups with four DisplayPort 2.1b outputs. The 82 RT cores and 328 tensor cores enable ray tracing and tensor workloads that the MX550 simply cannot handle. The 200 W TDP and dual-slot cooler indicate a desktop workstation card, so it is not for portable systems.

Who should pick the MX550? Only those constrained to a thin-and-light laptop where the 25 W TDP and IGP form factor are mandatory. Its 2 GB GDDR6 memory and 96.00 GB/s bandwidth are sufficient for basic video playback, office productivity, and light 2D acceleration. Its Turing architecture supports DirectX 12 (12_1), which covers most older games and applications. The MX550 is end-of-life, so new designs should look elsewhere, but for existing systems it remains a functional entry-level option.

The RTX PRO 4500 is the obvious choice for any workload where performance matters. The MX550 is a legacy part with no performance advantage in the recorded data. There is no scenario in these benchmarks where the MX550 wins, so the verdict is one-sided.
