Intel Arc 140T Mobile vs NVIDIA GeForce RTX 5070 Mobile Comparison

Where Each One Wins

The benchmark database separates these two mobile GPUs clearly by workload type. The Intel Arc 140T Mobile and NVIDIA GeForce RTX 5070 Mobile do not share a single recorded head-to-head benchmark, so the analysis relies on the available benchmark suites for the RTX 5070 Mobile and the architectural characteristics of the Arc 140T.

The RTX 5070 Mobile has recorded scores across nine tests spanning compute, graphics API performance, and 2D operations. Its percentile ranking sits at 75 among all GPUs in the database, with an average benchmark score of 29,928. The Arc 140T Mobile holds a 50th percentile ranking, with no individual benchmark scores recorded in the database. This places the two in different performance tiers, but the Arc 140T's integrated nature and low power envelope suggest it targets a distinct use case.

The RTX 5070 Mobile wins in every category where data exists. Its PassMark G3D score of 20,355 and GPU compute score of 8,279 show strong rasterization and compute throughput. The Geekbench OpenCL score of 122,238 and Vulkan score of 116,960 indicate robust general-purpose compute and cross-API compatibility. The PassMark DirectX 9, 10, 11, and 12 scores of 214, 129, 192, and 93 respectively, plus a G2D score of 896, round out the picture.

The Arc 140T Mobile, by contrast, is an integrated graphics processor (IGP) with a 35 W TDP. It shares system memory and relies on the host system's bandwidth. Its 1024 shading units, 64 texture mapping units, and 32 raster output units are roughly a quarter of the RTX 5070 Mobile's counts. The data suggests the Arc 140T is suited for light graphics work, media acceleration, and power-constrained notebooks, while the RTX 5070 Mobile is a dedicated mobile GPU for gaming and content creation.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the Arc 140T Mobile and RTX 5070 Mobile, so the comparison relies on the RTX 5070's recorded scores and the Arc 140T's architectural limits.

The largest advantage for the RTX 5070 Mobile appears in compute-heavy workloads. Its Geekbench OpenCL score of 122,238 and Vulkan score of 116,960 dwarf what an integrated GPU with 4.813 TFLOPS could plausibly achieve, though no Arc 140T scores exist to quantify the gap. The FP32 delta is instructive: 13.13 TFLOPS versus 4.813 TFLOPS, a 2.7x difference that explains why the RTX 5070 Mobile sits at the 75th percentile while the Arc 140T sits at the 50th.

Texture and pixel throughput tell a similar story. The RTX 5070 Mobile achieves 205.2 GTexel/s and 68.40 GPixel/s, while the Arc 140T Mobile manages 150.4 GTexel/s and 75.20 GPixel/s. Interestingly, the Arc 140T has a higher pixel rate despite its lower texture rate, a consequence of its 32 ROPs versus the RTX 5070's 48 ROPs and the clock speed differences.

The RTX 5070's PassMark scores show consistency across API generations: DirectX 9 at 214, DirectX 10 at 129, DirectX 11 at 192, and DirectX 12 at 93. These numbers indicate that the GPU performs best on legacy APIs, which is common for NVIDIA architectures with mature driver stacks. The Arc 140T has no equivalent scores, so no direct API comparison is possible.

Memory bandwidth is another decisive factor. The RTX 5070 Mobile's 384.0 GB/s over a 128-bit GDDR7 bus is a fixed resource, whereas the Arc 140T's system shared memory bandwidth is variable and dependent on the host platform. In practice, this means the Arc 140T cannot sustain high throughput in memory-intensive workloads, while the RTX 5070 Mobile has predictable performance.

Specification Differences

The two GPUs differ in nearly every measurable specification. The RTX 5070 Mobile uses the GB206 chip on TSMC's 5 nm process, while the Arc 140T uses Arrow Lake-H on the same 5 nm process from TSMC. Both are active production parts, but their release dates differ: the Arc 140T launched on January 12, 2025, and the RTX 5070 Mobile on April 14, 2025.

Clock speeds show a notable divergence. The Arc 140T has a base clock of 300 MHz and a boost of 2350 MHz, while the RTX 5070 Mobile runs at 907 MHz base and 1425 MHz boost. The Arc 140T's higher boost clock does not compensate for its smaller execution engine.

Memory is the most significant differentiator. The RTX 5070 Mobile has 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s bandwidth. The Arc 140T has no dedicated memory, using system shared memory with system-dependent bandwidth. This fundamentally limits the Arc 140T's ability to handle large textures or datasets.

The shader configuration also diverges sharply. The Arc 140T has 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. The RTX 5070 Mobile has 4608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores. The RTX 5070 Mobile's compute advantage is structural, not just clock-driven.

Power and interface differ as well. The Arc 140T draws 35 W and connects via IGP, while the RTX 5070 Mobile draws 50 W and uses PCIe 5.0 x16. Both are IGP in slot width and have no dedicated power connectors. The RTX 5070 Mobile's transistor count is 21,900 million on a 181 mm² die, while the Arc 140T's transistor count and die size are unknown.

Architecture Differences

The Arc 140T Mobile is built on Intel's Xe-LPG+ architecture, part of the Arc Graphics-M (Arrow Lake) generation. It uses Arrow Lake-H as its chip and succeeds HD Graphics-M. The architecture emphasizes efficiency for integrated use, with 1024 shading units and 8 ray tracing cores. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and its FP16 throughput of 9.626 TFLOPS (2:1 ratio) indicates a packed math capability that could assist with some compute tasks.

The RTX 5070 Mobile uses NVIDIA's Blackwell 2.0 architecture, built on the GB206 chip. It belongs to the GeForce 50 Mobile generation and succeeds GeForce 40 Mobile. Blackwell brings 144 tensor cores alongside 36 ray tracing cores, enabling dedicated AI acceleration and hardware ray tracing. Its FP16 performance of 13.13 TFLOPS (1:1 ratio) means it does not rely on packed math for half-precision workloads, which simplifies driver behavior and improves consistency.

The process nodes are identical, both 5 nm TSMC, but the RTX 5070 Mobile packs 21,900 million transistors into 181 mm², yielding a density of 121.0M per mm². The Arc 140T's transistor count and die size are not recorded, so a density comparison is impossible. However, the RTX 5070 Mobile's larger transistor budget supports its higher shader count and tensor core array.

Both GPUs support the same API set, but the RTX 5070 Mobile's tensor cores give it an architectural advantage for AI workloads, while the Arc 140T's 2:1 FP16 ratio offers a partial workaround for half-precision compute. The Arc 140T's 8 ray tracing cores are a minimal implementation, whereas the RTX 5070 Mobile's 36 cores provide substantially more ray tracing throughput. Neither GPU has recorded ray tracing benchmark scores in the database, so the practical impact remains qualitative.

The Verdict

The data positions the NVIDIA GeForce RTX 5070 Mobile as the higher-performance GPU by a wide margin. Its 13.13 TFLOPS FP32, 8 GB of GDDR7 with 384.0 GB/s bandwidth, and 144 tensor cores place it in the 75th percentile of all GPUs. Its average benchmark score of 29,928 aligns it with desktop-class parts like the RTX 3070 Ti, RTX 2080 Ti, RX 6800, and RX 6700, all within 1.7% of its score. For gaming, content creation, or compute tasks, the RTX 5070 Mobile is the clear choice among the two.

The Intel Arc 140T Mobile occupies a different niche. Its 35 W TDP, integrated design, and system shared memory make it suitable for ultraportable laptops where battery life and thermal limits take priority over raw performance. Its 4.813 TFLOPS and 50th percentile ranking indicate entry-level capability for light graphics, media playback, and basic 3D acceleration. Users who need a dedicated GPU with predictable performance should select the RTX 5070 Mobile, while those who prioritize efficiency and compact systems will find the Arc 140T adequate for undemanding workloads.

The benchmark data shows no scenario where the Arc 140T outperforms the RTX 5070 Mobile. The RTX 5070 Mobile wins on every recorded metric and every architectural advantage, including shading units, texture rate, memory bandwidth, and compute throughput. The only area where the Arc 140T shows a higher figure is pixel rate, at 75.20 GPixel/s versus 68.40 GPixel/s, but this single metric does not offset the RTX 5070 Mobile's superiority in all other categories.
