Intel Arc 130T Mobile vs Intel Arc Pro B70 Comparison

The Intel Arc 130T Mobile and the Intel Arc Pro B70 represent two distinct approaches within Intel’s graphics lineup. The 130T Mobile is an integrated solution aimed at portability, while the Pro B70 is a discrete workstation-oriented card. The database contains no comparative benchmark scores for these two parts, so the analysis below relies on their recorded specifications, architectural details, and performance metrics.

Head-to-Head Benchmarks

The database does not list any direct head-to-head benchmark results for the Intel Arc 130T Mobile versus the Intel Arc Pro B70. The recorded benchmark arrays for both devices are empty, and the wins counter shows zero for each side. Consequently, any performance comparison must be derived from the theoretical peak rates and hardware resources documented in their specification sheets.

The most striking difference appears in raw compute throughput. The Arc Pro B70 delivers 22.94 TFLOPS of FP32 performance, while the Arc 130T Mobile produces 3.942 TFLOPS. This represents a factor of 5.82: the Pro B70 is roughly 5.8 times faster in single-precision floating-point work. Similarly, FP16 performance shows the Pro B70 at 45.88 TFLOPS versus 7.885 TFLOPS for the mobile part, again a 5.8x gap. These numbers indicate that for any compute-heavy workload, the discrete card holds a commanding lead.

Pixel and texture throughput follow the same pattern. The Arc Pro B70 achieves 358.4 GPixel/s, whereas the 130T Mobile manages 61.60 GPixel/s. That is a 5.82x difference in pixel fill rate. Texture fill rate is 716.8 GTexel/s for the Pro B70 and 123.2 GTexel/s for the mobile chip, again a 5.8x advantage. These ratios are consistent because the architectural differences scale uniformly across these units.

Memory bandwidth tells a similar but even more pronounced story. The Arc Pro B70 uses 32 GB of GDDR6 on a 256-bit bus, providing 608.0 GB/s of bandwidth. The Arc 130T Mobile shares system memory, with bandwidth listed as System Dependent. In typical configurations, shared memory bandwidth is far lower than dedicated GDDR6, though the exact figure varies with the host platform. The discrete card’s 608.0 GB/s is a fixed, dedicated resource, whereas the mobile part must compete with CPU and other system traffic for memory access.

Clock speeds also favor the Pro B70. Its base clock is 2280 MHz and boost reaches 2800 MHz. The 130T Mobile starts at 300 MHz base and boosts to 2200 MHz. The higher base clock on the discrete card means sustained performance is closer to its peak, while the mobile part’s low base clock suggests power-saving behavior when idle or lightly loaded.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity exists. However, the physical resources behind those APIs are vastly different. The Arc Pro B70 has 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. The Arc 130T Mobile has 896 shading units, 56 TMUs, 28 ROPs, and 7 ray tracing cores. Each of these counts scales by the same 4.57x factor, except ROPs which scale by 4.57x as well (128 divided by 28 equals 4.57). This uniform scaling indicates a straightforward hardware multiplier rather than architectural divergence in these specific units.

Architecture Differences

The two GPUs come from different architectural families. The Intel Arc 130T Mobile uses the Xe-LPG+ architecture, built on the Arrow Lake-H chip. Its generation is listed as Arc Graphics-M (Arrow Lake). The Arc Pro B70 uses Xe2-HPG architecture, built on the BMG-G31 chip, and belongs to the Battlemage (Pro Series) generation. This generational split matters: Xe-LPG+ is a newer iteration of the integrated graphics lineage, while Xe2-HPG is Intel’s second-generation discrete architecture designed for higher performance and workstation features.

Both are fabricated on a 5 nm process at TSMC. The foundry and node are identical, so process technology does not explain the performance gap. The die size differs, however. The Arc Pro B70 has a die size of 368 mm², while the Arc 130T Mobile’s die size is listed as unknown. Transistor counts are unknown for both, so no comparison of transistor density is possible.

The memory subsystem presents the most fundamental architectural divergence. The Arc 130T Mobile uses System Shared memory, meaning it has no dedicated VRAM. Memory type, bus width, and bandwidth are all listed as System Shared or System Dependent. The Arc Pro B70, in contrast, uses 32 GB of GDDR6 with a 256-bit bus and 608.0 GB/s bandwidth. This is a dedicated, high-bandwidth memory pool that does not depend on host system configuration.

Clock behavior differs as well. The Arc 130T Mobile has a base clock of 300 MHz, which is exceptionally low, and a boost of 2200 MHz. The Arc Pro B70 has a base clock of 2280 MHz and a boost of 2800 MHz. The low base clock on the mobile part suggests aggressive power management, likely to fit within the 35 W TDP. The Pro B70’s 230 W TDP allows much higher sustained clocks.

Ray tracing hardware exists on both, but in very different quantities. The 130T Mobile has 7 RT cores, while the Pro B70 has 32. This 4.57x difference aligns with the shading unit count. However, the architectural generation may also affect ray tracing efficiency. Xe2-HPG is a newer architecture than Xe-LPG+, so per-core ray tracing performance could differ beyond the raw count. The database does not provide efficiency metrics, so this remains a qualitative observation.

The power delivery and physical design are also distinct. The Arc 130T Mobile is an IGP (integrated graphics processor) with no slot width, no power connectors, and no suggested PSU. It is embedded in a portable device. The Arc Pro B70 is a dual-slot card, 267 mm long, 110 mm tall, and 39 mm wide, requiring a single 8-pin power connector and a 550 W suggested PSU. It uses a PCIe 5.0 x16 bus interface, while the mobile part uses IGP as its bus interface.

Where Each One Wins

The Arc 130T Mobile wins in scenarios where physical integration and low power consumption are paramount. Its 35 W TDP is dramatically lower than the Pro B70’s 230 W. This makes it suitable for thin-and-light laptops, where a discrete card of the Pro B70’s size and power draw would be impossible. The mobile part has no power connectors and occupies no expansion slot, so it fits into the device’s mainboard without additional cooling or power infrastructure.

Display outputs on the 130T Mobile are Portable Device Dependent, meaning they are determined by the laptop or handheld system. This flexibility allows manufacturers to route outputs as needed. The Pro B70 offers fixed outputs: 1x HDMI 2.1a and 3x DisplayPort 2.1. For multi-monitor workstation setups, the Pro B70’s four outputs are a clear advantage. The mobile part’s output count depends entirely on the host device.

The Arc Pro B70 wins in every raw performance category recorded. Its 22.94 TFLOPS FP32 performance, 608.0 GB/s memory bandwidth, and 358.4 GPixel/s pixel rate place it in a different class. For rendering, simulation, AI inference, or any GPU-accelerated compute task, the discrete card provides roughly 5.8x the throughput of the mobile part. The 32 GB GDDR6 memory is also a significant advantage for large datasets, whereas the mobile part’s system-shared memory is limited by the host’s RAM and bandwidth.

The Pro B70’s release date is later, 2026-03-25, while the 130T Mobile released earlier on 2025-01-12. This timing difference means the Pro B70 benefits from a newer generation, Battlemage, that is more recent than the Arrow Lake integrated graphics. However, the 130T Mobile’s architecture, Xe-LPG+, is not the oldest; the database lists its predecessor as HD Graphics-M, indicating a significant leap from prior integrated graphics.

For users prioritizing battery life, portability, and a compact form factor, the 130T Mobile is the only choice. Its 35 W TDP and IGP design are incompatible with the Pro B70’s dual-slot 230 W card. Conversely, for stationary workstations needing maximum compute, the Pro B70 is the clear winner. The mobile part cannot match the discrete card’s memory bandwidth or raw throughput.
