Intel Arc A350M vs NVIDIA GeForce RTX 4070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between these two mobile GPUs. In the two shared benchmark tests, the NVIDIA GeForce RTX 4070 Mobile wins both outright, with margins that are difficult to overstate.

In Geekbench OpenCL, the RTX 4070 Mobile scores 109,197, while the Intel Arc A350M manages 24,546. That is a 344.9% advantage for the NVIDIA part. To put that in perspective, the Arc A350M needs to more than quadruple its output to match the RTX 4070 Mobile in this workload. The Geekbench Vulkan result tells a similar story: 108,367 for the RTX 4070 Mobile versus 24,747 for the Arc A350M, a 337.9% lead.

The NVIDIA GPU also holds a significant edge in the broader database average. Its average benchmark score is 27,435, compared to 24,647 for the Intel part. That is roughly an 11% gap overall, though the head-to-head results suggest the real-world difference in compute-heavy tasks is far larger. The Arc A350M's average is propped up by its two recorded scores, both of which sit in the mid-24,000 range, while the RTX 4070 Mobile's average reflects a much wider set of tests including DirectX 9 through 12, OpenCL, Vulkan, and compute workloads.

The Arc A350M does not win a single recorded benchmark against the RTX 4070 Mobile. The wins tally is 2 for NVIDIA, 0 for Intel. That is a clean sweep, though it is notably the dataset only includes two overlapping tests. The RTX 4070 Mobile's Passmark G3D score of 19,587 and its Passmark GPU Compute score of 8,399 further illustrate its strength in rasterization and general compute, but the Arc A350M has no comparable Passmark entries in the database, so those cannot be directly compared.

In terms of percentile ranking, the RTX 4070 Mobile sits at the 73rd percentile of all GPUs, while the Arc A350M is at the 70th. The percentile difference is small, but the raw score gap is enormous. This suggests the Arc A350M's percentile is buoyed by the large number of older or weaker GPUs in the database, not by any real competitiveness with the RTX 4070 Mobile.

Architecture Differences

The two GPUs come from different architectural families and different process nodes. The RTX 4070 Mobile uses the AD106 chip built on Ada Lovelace architecture, manufactured by TSMC on a 5 nm process. The Arc A350M uses the DG2-128 chip based on Xe-HPG architecture, also from TSMC but on a 6 nm node. The 5 nm node gives NVIDIA a density advantage before any microarchitectural differences are considered.

Transistor counts differ sharply. The AD106 packs 22,900 million transistors into a die size of 188 mm², yielding a density of 121.8M transistors per square millimeter. The DG2-128 contains 7,200 million transistors across 157 mm², for a density of 45.9M per square millimeter. NVIDIA packs more than three times the transistors into a die that is only 31 mm² larger. That transistor budget translates directly into compute resources: the RTX 4070 Mobile has 4,608 shading units, 144 texture mapping units, and 48 render output units. The Arc A350M has 768 shading units, 48 TMUs, and 24 ROPs.

Ray tracing hardware also differs. The RTX 4070 Mobile has 36 ray tracing cores, while the Arc A350M has 6. The NVIDIA part also carries 144 tensor cores, while the Intel GPU has no tensor core count listed in the database. That means AI-accelerated workloads, particularly those that rely on tensor operations, are effectively exclusive to the RTX 4070 Mobile.

Memory architecture is another major divergence. The RTX 4070 Mobile uses 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s of bandwidth. The Arc A350M uses 4 GB of GDDR6 on a 64-bit bus, yielding 112.0 GB/s. The NVIDIA GPU has double the memory capacity and more than double the bandwidth. This alone will affect performance in texture-heavy scenes, high-resolution rendering, and any workload that spills past the 4 GB frame buffer of the Intel part.

Clock behavior is also worth noting. The RTX 4070 Mobile has a base clock of 1395 MHz and a boost of 1695 MHz. The Arc A350M has a lower base of 1150 MHz but a much higher boost of 2200 MHz. Intel's higher boost clock does not compensate for its far smaller execution resource pool. The FP32 throughput tells the story: the RTX 4070 Mobile delivers 15.62 TFLOPS, while the Arc A350M delivers 3.379 TFLOPS. The NVIDIA part is roughly 4.6 times faster in single-precision compute. In FP16, the RTX 4070 Mobile sustains 15.62 TFLOPS with a 1:1 ratio, while the Arc A350M reaches 6.758 TFLOPS with a 2:1 ratio. NVIDIA still leads, but Intel's FP16 advantage relative to its own FP32 is notable.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use PCIe 4.0 x8. Both are marked as IGP slot width with portable-device-dependent display outputs. The production status differs: the RTX 4070 Mobile is active, while the Arc A350M is end-of-life.

Where Each One Wins

The RTX 4070 Mobile wins in every recorded category. In OpenCL, it is 344.9% ahead. In Vulkan, it is 337.9% ahead. Those are not narrow victories; they represent different performance tiers entirely. The RTX 4070 Mobile is positioned among desktop-class GPUs. Its nearest rivals in the database include the NVIDIA GeForce RTX 3090 at a 0.5% lower average score, the AMD Radeon RX 6700 XT at a 0% delta, and the AMD Radeon Pro Vega 20 at a 1.5% lower score. That is rarefied company for a mobile part.

The Arc A350M, by contrast, sits alongside the AMD Radeon RX 590 at a 0.4% lower average score, the NVIDIA RTX A5000 Mobile at 0.5% lower, the AMD Radeon RX 6600 XT at 0.8% higher, and the NVIDIA GeForce GTX 1630 at 1.5% higher. The Intel GPU is competitive with mid-range desktop GPUs from several generations ago, but it is not in the same league as the RTX 4070 Mobile.

For gaming, the RTX 4070 Mobile is the clear choice if the workload fits within its 8 GB frame buffer. The Arc A350M's 4 GB limit will constrain modern titles at higher settings or resolutions. For ray tracing workloads, the RTX 4070 Mobile's 36 RT cores far exceed the Arc A350M's 6, and its tensor cores enable DLSS-class features that the Intel GPU cannot match. The Arc A350M's higher boost clock and 2:1 FP16 ratio suggest it can handle lighter compute tasks efficiently, but only at much lower absolute performance levels.

The RTX 4070 Mobile is better suited to content creation, AI inference, and high-refresh-rate gaming. The Arc A350M might suffice for light productivity, esports titles, or older games, but the data does not show it winning in any benchmark, so its only real advantage is the unspecified nature of those scenarios.

The most consequential differences are memory capacity, bandwidth, compute unit counts, and TDP. The RTX 4070 Mobile draws 115 W versus 25 W for the Arc A350M, which explains much of the performance gap. The NVIDIA GPU is a high-power part designed for performance laptops, while the Intel GPU targets low-power thin-and-light systems. The 90 W difference is not just a number, it dictates the thermal and power delivery requirements of the host laptop.

The Verdict

The data is unambiguous. The NVIDIA GeForce RTX 4070 Mobile outclasses the Intel Arc A350M across every recorded metric, with margins ranging from roughly 338% to 345% in the direct comparisons. The RTX 4070 Mobile has more than double the memory bandwidth, four times the shading units, six times the ray tracing cores, and more than double the memory capacity. Its average benchmark score of 27,435 places it alongside desktop GPUs like the RTX 3090 and RX 6700 XT, while the Arc A350M's 24,647 average aligns it with older mid-range parts like the RX 590 and GTX 1630.

For a buyer choosing between a laptop with the RTX 4070 Mobile and one with the Arc A350M, the decision is straightforward if performance is the priority. The RTX 4070 Mobile will handle modern games, ray tracing, and compute workloads at a level the Arc A350M cannot approach. The Arc A350M's only advantages are its 25 W TDP and its lower power footprint, which could matter for ultra-portable notebooks where battery life and thermals are paramount.

The RTX 4070 Mobile is an active product with a 2023 release date, while the Arc A350M is end-of-life with a 2022 release date. For long-term usability, driver support, and future software compatibility, the NVIDIA part is the safer choice. The Arc A350M is best suited for a secondary machine or a specific low-power use case where its 4 GB frame buffer and 112.0 GB/s bandwidth are sufficient. For anyone who needs actual graphics performance, the RTX 4070 Mobile is the only rational pick from the recorded data.
