GPU Comparison

Intel Arc A550M and NVIDIA GeForce RTX 5090 Mobile occupy opposite ends of the mobile graphics spectrum, and the benchmark data reflects a decisive performance gap. The RTX 5090 Mobile wins both available head-to-head tests by a wide margin, posting scores that are roughly four times higher than the Arc A550M in OpenCL and Vulkan workloads. While the Arc A550M holds a higher percentile ranking among all GPUs at 86 versus the RTX 5090 Mobile’s 84, this is a function of its average benchmark score of 49,737 compared to 45,152, which is skewed by the RTX 5090 Mobile’s inclusion of older DirectX 9 and 2D tests that drag down its aggregate. In raw compute and modern API performance, the RTX 5090 Mobile is in a different class.

The Verdict

The data points to a simple conclusion: the NVIDIA GeForce RTX 5090 Mobile is the superior choice for anyone prioritizing raw performance in modern workloads. Its Geekbench OpenCL score of 201,834 crushes the Intel Arc A550M’s 49,894, a delta of -75.3% from the Intel part’s perspective. Similarly, in Geekbench Vulkan, the RTX 5090 Mobile scores 198,405 against the Arc A550M’s 49,580, a -75% gap. For gaming, content creation, or compute tasks that leverage Vulkan or OpenCL, the RTX 5090 Mobile is the clear pick.

However, the Arc A550M is not without its merits. Its average benchmark score of 49,737 places it at the 86th percentile of all GPUs, which is higher than the RTX 5090 Mobile’s 84th percentile, despite the latter’s far higher peak scores. This suggests the Arc A550M is a more consistent performer across a broader range of legacy and lightweight tasks, likely due to its lower power envelope and simpler architecture. The RTX 5090 Mobile’s average is pulled down by weak Passmark scores in DirectX 9 (324), DirectX 10 (183), and 2D (1057), which may reflect driver optimization issues or architectural inefficiencies in those older APIs.

Who should pick which? If the workload is modern, GPU-intensive, and API-forward (OpenCL, Vulkan, DirectX 12), the RTX 5090 Mobile is the only rational choice, it outperforms the Arc A550M by roughly 300% in those tests. If the workload is legacy-centric, power-constrained, or requires a broad, steady performance baseline, the Arc A550M’s higher percentile and lower TDP (60 W vs 95 W) make it a viable alternative, though its absolute performance ceiling is far lower. The RTX 5090 Mobile is also an active product with a successor lineage, while the Arc A550M is end-of-life, which matters for long-term driver support and availability.

The RTX 5090 Mobile also has a predecessor (GeForce 40 Mobile), while the Arc A550M has none listed.

Head-to-Head Benchmarks

The head-to-head data is lopsided. In Geekbench OpenCL, the RTX 5090 Mobile scores 201,834 against the Arc A550M’s 49,894, a delta of -75.3% for the Intel part. In Geekbench Vulkan, the RTX 5090 Mobile scores 198,405 against the Arc A550M’s 49,580, a delta of -75%. These are the only two shared benchmark tests, and the RTX 5090 Mobile wins both outright.

Looking at the RTX 5090 Mobile’s broader benchmark suite, it shows particular strength in 3DMark Steel Nomad DX12 (5,871) and Passmark G3D (30,034), while its Passmark GPU Compute score is 13,401. The Arc A550M has no equivalent tests in its pack, so direct comparison is limited to the Geekbench results. The RTX 5090 Mobile’s OpenCL score is over 4x higher than the Arc’s, and its Vulkan score is nearly 4x higher, indicating that the NVIDIA GPU’s architectural advantages scale directly into real-world API performance.

The Arc A550M’s nearest rivals include the NVIDIA GeForce RTX 5070 Ti (avg score 49,957, delta -0.4%) and AMD Radeon RX Vega 64 (avg score 50,001, delta -0.5%), placing it in a mid-range tier. The RTX 5090 Mobile’s nearest rivals include the AMD Radeon Pro 5500 XT (avg score 45,384, delta -0.5%) and Intel Arc A730M (avg score 45,592, delta -1%), which are lower-tier parts. This suggests that while the RTX 5090 Mobile has higher peak performance, its average score is dragged down by inconsistent results across its benchmark suite, whereas the Arc A550M is more consistent.

Where Each One Wins

The RTX 5090 Mobile is the definitive winner in modern, compute-intensive scenarios. Its OpenCL and Vulkan scores are roughly four times higher than the Arc A550M’s, making it the obvious choice for 3D rendering, machine learning inference, video encoding, and high-end gaming at high resolutions. Its 24 GB GDDR7 memory and 896 GB/s bandwidth provide ample headroom for large datasets and textures, and its 82 ray tracing cores and 328 tensor cores enable hardware-accelerated ray tracing and AI features that the Arc A550M cannot match. The RTX 5090 Mobile also supports PCIe 5.0, which future-proofs it for next-generation platforms.

The Arc A550M wins in efficiency and consistency. Its 60 W TDP is 35 W lower than the RTX 5090 Mobile, making it better suited for ultra-portable laptops where thermals and battery life are critical. Its higher percentile ranking (86th vs 84th) and higher average benchmark score (49,737 vs 45,152) indicate that it delivers a steadier experience across a wide range of workloads, particularly legacy APIs like DirectX 9 and 10, where the RTX 5090 Mobile’s Passmark scores are notably weak (324 and 183, respectively). For users running older games or productivity applications that do not leverage modern compute APIs, the Arc A550M may offer a more stable, predictable performance profile without the power draw of a flagship GPU. Its end-of-life status, however, means software optimization may stagnate, while the RTX 5090 Mobile is actively supported and positioned for future driver improvements.
