Intel Arc A730M vs NVIDIA GeForce RTX 5090 Mobile Comparison

The Intel Arc A730M and NVIDIA GeForce RTX 5090 Mobile represent two distinct generations of mobile graphics, separated by a significant performance gulf despite sharing the same 85th percentile ranking among all GPUs. The benchmark data shows a clear hierarchy: the RTX 5090 Mobile wins every head-to-head test by a wide margin, while the Arc A730M’s average score of 45,592 sits just 1% above the RTX 5090 Mobile’s 45,152 average, a statistical tie that belies the extreme variance in individual workloads. This analysis breaks down where each GPU excels, the architectural reasoning behind the divide, and what the numbers mean for real-world usage.

Where Each One Wins

The performance split between these two GPUs is not a matter of niche advantages; it is a categorical sweep. In the three shared benchmark tests, the NVIDIA GeForce RTX 5090 Mobile claims victory in 100% of them, leaving the Intel Arc A730M with zero wins. The RTX 5090 Mobile’s dominance is most pronounced in the 3DMark Steel Nomad DX12 test, where it scores 5,871 versus the Arc A730M’s 1,732, a delta of -70.5% for the Intel part. This is a synthetic workload designed to stress modern DirectX 12 rendering pipelines, and the result indicates that the NVIDIA GPU handles complex geometry and compute-heavy scenes with far greater efficiency.

The Arc A730M’s only competitive territory is its average benchmark score, which edges out the RTX 5090 Mobile by 1% (45,592 vs. 45,152). This is misleading, however, because the RTX 5090 Mobile has a much larger benchmark suite—10 tests compared to the Arc A730M’s 3—which includes older DirectX 9, 10, and 11 workloads where the NVIDIA GPU still posts respectable numbers. For instance, the RTX 5090 Mobile scores 324 in Passmark DirectX 9 and 269 in DirectX 11, while the Arc A730M has no equivalent data. In practical terms, the Arc A730M is not competitive in any modern or legacy workload where both have been measured.

The NVIDIA GPU also wins decisively in compute-oriented tests. In Geekbench OpenCL, the RTX 5090 Mobile scores 201,834 against the Arc A730M’s 70,352, a -65.1% delta. Similarly, in Geekbench Vulkan, the NVIDIA part hits 198,405 versus 64,693 for the Intel GPU, a -67.4% delta. These results indicate that for any application leveraging general-purpose GPU compute—whether for rendering, physics simulation, or AI inference—the RTX 5090 Mobile is the only viable choice between the two. The Arc A730M’s 85th percentile ranking confirms its position among all GPUs, but against this specific rival, it offers no winning scenarios.

Architecture Differences

The underlying silicon tells a story of two very different design philosophies. The Intel Arc A730M is built on the Xe-HPG architecture, specifically the DG2-512 chip, fabricated on a 6 nm process at TSMC. This is a first-generation Alchemist design, and it packs 21,700 million transistors into a 406 mm² die, yielding a transistor density of 53.4 million per square millimeter. In contrast, the NVIDIA GeForce RTX 5090 Mobile uses the Blackwell 2.0 architecture with the GB203 chip, manufactured on a more advanced 5 nm process, also at TSMC. This chip contains 45,600 million transistors on a smaller 378 mm² die, achieving a much higher density of 120.6 million per square millimeter.

The transistor count disparity is stark: the RTX 5090 Mobile has more than double the transistors of the Arc A730M (45,600 million vs. 21,700 million). This allows NVIDIA to field a dramatically larger execution engine. The RTX 5090 Mobile has 10,496 shading units, 328 texture mapping units, and 112 ROPs, compared to the Arc A730M’s 3,072 shading units, 192 TMUs, and 96 ROPs. The NVIDIA GPU also features 82 ray tracing cores and 328 tensor cores, while the Intel part has just 24 ray tracing cores and no dedicated tensor core count listed. This explains the RTX 5090 Mobile’s massive lead in compute-heavy benchmarks.

Clock speeds tell a different story, with the Arc A730M running a higher base clock of 1100 MHz and boost clock of 2050 MHz, versus the RTX 5090 Mobile’s 990 MHz base and 1515 MHz boost. However, the NVIDIA GPU compensates with sheer parallel throughput. The memory subsystems are also generations apart: the Arc A730M uses 12 GB of GDDR6 on a 192-bit bus, delivering 336.0 GB/s of bandwidth, while the RTX 5090 Mobile uses 24 GB of GDDR7 on a 256-bit bus, achieving 896.0 GB/s. This 2.7x bandwidth advantage is critical for high-resolution textures and data-intensive workloads.

Power efficiency is another differentiator. The Arc A730M has a TDP of 80 W, while the RTX 5090 Mobile is rated at 95 W, a modest increase for a massive performance jump. Both are IGP slot-width designs with no power connectors listed, but the NVIDIA part uses the newer PCIe 5.0 x16 interface versus the Arc A730M’s PCIe 4.0 x16. The RTX 5090 Mobile also has a release date of March 26, 2025, and is marked as active production, while the Arc A730M is end-of-life.

Head-to-Head Benchmarks

The three shared benchmarks provide a clear quantitative picture of the performance gap. In 3DMark Steel Nomad DX12, the RTX 5090 Mobile scores 5,871, which is 3.4x higher than the Arc A730M’s 1,732. The delta of -70.5% means the Intel GPU delivers less than a third of the NVIDIA part’s performance in this test. This is not a marginal difference; it represents a generational leap in rasterization and compute capabilities.

Geekbench OpenCL results show a similar trend. The RTX 5090 Mobile’s score of 201,834 is nearly three times the Arc A730M’s 70,352, a delta of -65.1%. OpenCL is a cross-platform compute API, and this result suggests that the NVIDIA GPU’s 328 tensor cores and higher shader count provide a massive advantage in parallel processing tasks. The Arc A730M’s lack of tensor cores likely hampers its performance in AI and machine learning workloads, which are increasingly common in modern applications.

Geekbench Vulkan follows the same pattern, with the RTX 5090 Mobile scoring 198,405 against the Arc A730M’s 64,693, a delta of -67.4%. Vulkan is a low-overhead graphics API used in many modern games and professional applications. The NVIDIA GPU’s advantage here is consistent with its architectural superiority, including its higher texture rate (496.9 GTexel/s vs. 393.6 GTexel/s) and pixel rate (169.7 GPixel/s vs. 196.8 GPixel/s, where the Arc actually leads). Interestingly, the Arc A730M has a higher pixel rate, but this does not translate into a win in any tested workload, indicating that other bottlenecks dominate.

The RTX 5090 Mobile also has additional benchmark data not available for the Arc A730M, including Passmark scores across DirectX 9 (324), DirectX 10 (183), DirectX 11 (269), and DirectX 12 (138), as well as Passmark G2D (1,057), G3D (30,034), and GPU Compute (13,401). These results, while not directly comparable to the Intel part, show that the NVIDIA GPU maintains solid performance across legacy APIs, which is important for backward compatibility in older software.

FAQ

Q: Which GPU has a higher average benchmark score?

A: The Intel Arc A730M has a slightly higher average score of 45,592, which is 1% above the NVIDIA GeForce RTX 5090 Mobile’s 45,152. However, this is based on different benchmark suites, and the RTX 5090 Mobile wins every shared test by a large margin.

Q: What is the biggest performance difference in the head-to-head tests?

A: The largest gap is in 3DMark Steel Nomad DX12, where the RTX 5090 Mobile scores 5,871 versus the Arc A730M’s 1,732, a delta of -70.5%. This means the Intel GPU is roughly 29.5% as fast as the NVIDIA part in this workload.

Q: How do the memory configurations compare?

A: The RTX 5090 Mobile has 24 GB of GDDR7 memory on a 256-bit bus, providing 896.0 GB/s of bandwidth. The Arc A730M has 12 GB of GDDR6 on a 192-bit bus, delivering 336.0 GB/s. The NVIDIA GPU has double the capacity and 2.7x the bandwidth.

Q: Are there any workloads where the Arc A730M wins?

A: No. In the three shared benchmarks, the RTX 5090 Mobile wins all of them. The Arc A730M’s only advantage is its average score, which is not a direct comparison. The Intel GPU does have a higher pixel rate (196.8 GPixel/s vs. 169.7 GPixel/s), but this does not result in a benchmark victory.

Q: What is the transistor count difference?

A: The RTX 5090 Mobile has 45,600 million transistors, while the Arc A730M has 21,700 million. This is a 2.1x difference in favor of the NVIDIA GPU, which enables its higher core counts and tensor core implementation.

Q: Which GPU has a higher boost clock?

A: The Arc A730M has a higher boost clock of 2050 MHz, compared to the RTX 5090 Mobile’s 1515 MHz. However, the NVIDIA GPU’s higher core count and memory bandwidth more than compensate for its lower clock speed.
