Intel Arc 130T Mobile vs Intel Arc Pro B370 Comparison

The Intel Arc 130T Mobile and Intel Arc Pro B370 are both integrated graphics solutions from Intel, but they serve different performance tiers and are built on distinct generations of technology. The database shows that the Arc Pro B370 delivers substantially higher raw compute throughput, while the Arc 130T Mobile offers a different balance of features and efficiency characteristics. The data indicates these are not direct replacements for one another, but rather options for different system priorities.

The Verdict

The Intel Arc Pro B370 is the clear choice for users who prioritize raw graphics compute performance and do so with lower power consumption. The recorded specifications show the B370 delivers 6.144 TFLOPS of FP32 performance, which is 55.9% higher than the 3.942 TFLOPS of the Arc 130T Mobile. This advantage extends to FP16 throughput, where the B370 provides 12.29 TFLOPS versus 7.885 TFLOPS for the 130T, again a 55.9% lead. For any workload reliant on shader throughput, the B370 is the superior part.

However, the Arc 130T Mobile has its own advantages in specific areas. Its pixel rate is 61.60 GPixel/s, which is 28.3% faster than the B370's 48.00 GPixel/s. Similarly, its texture rate of 123.2 GTexel/s exceeds the B370's 96.00 GTexel/s by 28.3%. These figures suggest the 130T is more efficient at fill-rate-bound tasks, such as certain types of rasterization work at lower resolutions. The 130T also uses a larger process node, which can have implications for manufacturing and integration priorities that are not captured in raw performance metrics alone.

Given the data, the verdict is straightforward. The Arc Pro B370 is the pick for compute-heavy applications, AI inference, and any scenario where raw shader performance is the bottleneck. The Arc 130T Mobile is the pick for systems where fill-rate characteristics and the specific integration profile of a 5 nm TSMC chip are more important than raw FP32 throughput. The B370 also has a lower TDP of 25 W compared to the 130T's 35 W, making it a more power-efficient choice in the database's metrics.

Architecture Differences

The two integrated GPUs are built on fundamentally different architectures and manufacturing processes. The Intel Arc 130T Mobile is based on the Xe-LPG+ architecture and is part of the Arc Graphics-M (Arrow Lake) generation. It is fabricated on a 5 nm process at TSMC. In contrast, the Intel Arc Pro B370 uses the newer Xe3-LPG architecture and belongs to the Arc Graphics-WM (Panther Lake) generation. Its process node is 3 nm, and it is manufactured at Intel's own foundry.

These architectural differences lead to distinct resource allocations. The B370's Xe3-LPG design provides 1280 shading units, 40 TMUs, and 20 ROPs. The 130T's Xe-LPG+ design provides fewer shading units at 896, but a different texture and pixel pipeline setup with 56 TMUs and 28 ROPs. The B370 has a higher count of RT cores at 10, compared to the 130T's 7.

The memory architecture is similar in nature, with both using system shared memory and having a bus width that is system dependent. The bandwidth for both is also system dependent. The transistor counts and die sizes for both are listed as unknown in the database, so a direct comparison of those physical characteristics is not possible.

Specification Differences

The database records several key differences between the two integrated GPUs. The most prominent is the boost clock speed. The Intel Arc Pro B370 boosts to 2400 MHz, while the Intel Arc 130T Mobile boosts to 2200 MHz. Both have a base clock of 300 MHz.

The compute unit counts differ significantly. The B370 has 1280 shading units, 40 TMUs, and 20 ROPs. The 130T has 896 shading units, 56 TMUs, and 28 ROPs. The B370 also has 10 RT cores to the 130T's 7.

The process node is a major differentiator. The 130T is built on a 5 nm process at TSMC, while the B370 is built on a 3 nm process at Intel. The TDP also differs, with the 130T rated at 35 W and the B370 at 25 W. The B370 lists power connectors as "None", while the 130T has a null entry for this field.

The release dates are far apart in the database. The Intel Arc 130T Mobile was released on 2025-01-12, while the Intel Arc Pro B370 was released on 2026-01-26. The predecessors are also different: the 130T succeeded "HD Graphics-M", while the B370 succeeded "HD Graphics-WM". Both are listed as Active in production status.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two GPUs. However, the recorded specification data provides a clear basis for comparing their theoretical performance ceilings.

In raw compute throughput, the Intel Arc Pro B370 wins decisively. Its FP32 performance of 6.144 TFLOPS is 55.9% higher than the 3.942 TFLOPS of the Intel Arc 130T Mobile. The FP16 performance follows the same pattern, with the B370 delivering 12.29 TFLOPS versus the 130T's 7.885 TFLOPS.

The texture and pixel rates tell the opposite story. The 130T achieves a texture rate of 123.2 GTexel/s, which is 28.3% higher than the B370's 96.00 GTexel/s. The pixel rate advantage is identical in percentage terms, with the 130T at 61.60 GPixel/s versus the B370's 48.00 GPixel/s.

The shading unit count favors the B370. With 1280 shading units, it has 42.9% more units than the 130T's 896. The RT core count also favors the B370, with 10 RT cores compared to the 130T's 7, a 42.9% difference.

The boost clock difference is modest. The B370's 2400 MHz boost is 9.1% higher than the 130T's 2200 MHz boost. The TDP difference is also notable, with the B370 drawing 28.6% less power than the 130T.

Where Each One Wins

The Intel Arc Pro B370 wins in scenarios that depend heavily on shader compute and ray tracing. Its higher FP32 and FP16 throughput makes it the stronger choice for general-purpose GPU compute, scientific simulations, and workloads that leverage parallel floating-point operations. The higher count of shading units and RT cores reinforces this advantage, suggesting better performance in ray-traced rendering and complex shader effects.

The Intel Arc 130T Mobile wins in scenarios where fill rate is the limiting factor. Its higher texture rate and pixel rate indicate it can handle texture-heavy rendering and high pixel throughput more efficiently than the B370. This could translate to better performance in certain legacy or optimized game engines that are fill-rate bound, as well as in 2D compositing or display workloads.

The B370 also wins on power efficiency, with a 25 W TDP compared to the 130T's 35 W. This makes it a more attractive option for systems where thermal headroom and battery life are critical, assuming the performance requirements are met.

The 130T's 5 nm TSMC process and its earlier release date suggest it is a mature, established design within its generation. The B370's 3 nm Intel process and later release date indicate it is the newer platform. The database does not provide transistor counts or die sizes, so conclusions about physical efficiency or integration complexity cannot be drawn.

In summary, the Arc Pro B370 is the stronger compute part with better power characteristics, while the Arc 130T Mobile holds an edge in fill-rate metrics. Each GPU wins in its respective domain, and the choice between them depends entirely on which performance characteristic is prioritized for the target system.
