Intel Arc Pro B370 vs NVIDIA GeForce RTX 5070 Mobile Comparison

Intel Arc Pro B370 and NVIDIA GeForce RTX 5070 Mobile occupy very different positions in the mobile graphics landscape. The RTX 5070 Mobile is a discrete-class solution with a substantial specification advantage, while the Arc Pro B370 is an integrated processor with a much lower power envelope. The recorded data shows a clear performance hierarchy, but the analysis of where each part fits requires a close look at the architectural and power characteristics.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results for the Intel Arc Pro B370, as its average benchmark score is recorded as 0. The NVIDIA GeForce RTX 5070 Mobile, in contrast, has a full set of measurements. Its average benchmark score is 29928, which places it in the 75th percentile of all GPUs in the database. The Arc Pro B370 sits at the 50th percentile, a significant gap that indicates the NVIDIA part is positioned well above the Intel integrated solution in raw compute performance.

The RTX 5070 Mobile delivers 13.13 TFLOPS of FP32 performance, while the Arc Pro B370 delivers 6.144 TFLOPS. This represents a 2.1x advantage for the NVIDIA part in single-precision compute. The gap narrows somewhat in FP16, where the Intel part uses a 2:1 rate to reach 12.29 TFLOPS, but the NVIDIA part still leads at 13.13 TFLOPS with a 1:1 implementation. The RTX 5070 Mobile also leads in texture and pixel throughput, with 205.2 GTexel/s versus 96.00 GTexel/s for the Intel part, and 68.40 GPixel/s versus 48.00 GPixel/s.

The RTX 5070 Mobile's Geekbench OpenCL score is 122238, and its Vulkan score is 116960. These are the only cross-API measurements available for the pair, and they confirm that the NVIDIA architecture scales well across different compute interfaces. The PassMark suite shows consistent results for the NVIDIA part, with a G3D score of 20355 and a GPU compute score of 8279. The Intel Arc Pro B370 has no recorded benchmark scores, so all quantitative comparisons must rely on the specification-level data in the database.

The nearest rivals for the RTX 5070 Mobile provide context for its measured performance. The NVIDIA GeForce RTX 3070 Ti scores 29945, which is 0.1% ahead of the RTX 5070 Mobile. The AMD Radeon RX 6800 scores 30095, putting it 0.6% ahead. The NVIDIA GeForce RTX 2080 Ti scores 29783, 0.5% behind, and the AMD Radeon RX 6700 scores 30433, 1.7% ahead. These deltas are all within a narrow band, indicating that the RTX 5070 Mobile performs at a level comparable to these previous-generation desktop parts, despite being a mobile implementation.

Where Each One Wins

The RTX 5070 Mobile wins decisively in every measured performance category. Its memory subsystem is a major differentiator. The NVIDIA part has 8 GB of dedicated GDDR7 memory on a 128-bit bus, delivering 384.0 GB/s of bandwidth. The Intel Arc Pro B370 uses system shared memory with bandwidth that is system dependent. This means the Intel part's memory performance is not fixed, but in practice it cannot match the dedicated, high-bandwidth GDDR7 implementation of the NVIDIA part.

The RTX 5070 Mobile also wins on compute resources. It has 4608 shading units, 144 texture mapping units, and 48 render output units. The Arc Pro B370 has 1280 shading units, 40 TMUs, and 20 ROPs. The NVIDIA part has 36 RT cores and 144 tensor cores, while the Intel part has 10 RT cores and no tensor cores listed. For workloads that use tensor operations, the RTX 5070 Mobile has a hardware advantage that the Intel part cannot address.

The Arc Pro B370 wins in power efficiency, at least on paper. Its TDP is 25 W, half the 50 W TDP of the RTX 5070 Mobile. For thermally constrained designs, this is a meaningful difference. The Intel part is also fabricated on a 3 nm process, while the NVIDIA part uses a 5 nm process from TSMC. The smaller process node suggests the Intel part has a density advantage, though the RTX 5070 Mobile's 21,900 million transistors on a 181 mm² die give it a density of 121.0M per mm².

Architecture Differences

The two parts come from fundamentally different design philosophies. The Intel Arc Pro B370 uses the Xe3-LPG architecture on the Panther Lake chip. It is an integrated graphics processor, meaning it has no separate memory bus, no power connectors, and relies entirely on system resources. Its base clock is 300 MHz with a boost clock of 2400 MHz. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its process node is 3 nm, and it is manufactured by Intel.

The NVIDIA GeForce RTX 5070 Mobile uses the Blackwell 2.0 architecture on the GB206 chip. It is part of the GeForce 50-series and the GeForce 50 Mobile generation. Its base clock is 907 MHz with a boost clock of 1425 MHz. The memory clock is 1500 MHz with 24 Gbps effective data rate. It uses a PCIe 5.0 x16 bus interface, whereas the Intel part uses an integrated graphics processor interface. The NVIDIA part also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API support is identical between the two.

The transistor counts are starkly different. The RTX 5070 Mobile has 21,900 million transistors, while the Intel part's transistor count is listed as unknown. The die size for the NVIDIA part is 181 mm², and the Intel die size is also unknown. The RTX 5070 Mobile is manufactured by TSMC on a 5 nm process, while the Intel part is on Intel's 3 nm process. This does not automatically translate to a performance advantage, as the NVIDIA part uses its larger transistor budget for more shading units, TMUs, ROPs, RT cores, and tensor cores.

The memory architecture is the most consequential difference. The RTX 5070 Mobile has 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s of bandwidth. The Intel Arc Pro B370 has system shared memory, meaning its bandwidth and capacity are determined by the host system's RAM. This makes the Intel part's performance highly variable, while the NVIDIA part has a fixed, predictable memory subsystem.

The power delivery also differs. The RTX 5070 Mobile has a 50 W TDP and no power connectors, while the Intel part has a 25 W TDP and no power connectors. Both are listed as IGP in slot width, meaning they are designed to be integrated into a motherboard or system rather than installed as a separate card. The display outputs for both are listed as portable device dependent.

The Verdict

The RTX 5070 Mobile is the clear performance leader in this comparison. Its average benchmark score of 29928 places it in the 75th percentile, and it sits within 1.7% of the AMD Radeon RX 6700 and within 0.6% of the AMD Radeon RX 6800. The Intel Arc Pro B370 has no recorded benchmark scores to challenge this position. The NVIDIA part offers more than twice the FP32 throughput, a dedicated 8 GB GDDR7 memory subsystem with 384.0 GB/s of bandwidth, and 4608 shading units. It also includes 144 tensor cores, which the Intel part lacks entirely.

The Arc Pro B370 is not without its merits. Its 25 W TDP is half that of the RTX 5070 Mobile, and its 3 nm process node indicates a modern manufacturing approach. For systems where power is the primary constraint and compute requirements are modest, the Intel part could be adequate. Its 10 RT cores provide some ray tracing capability, and its FP16 throughput of 12.29 TFLOPS is close to the NVIDIA part's 13.13 TFLOPS, though the NVIDIA part achieves this at 1:1 ratio while the Intel part uses a 2:1 rate.

The data supports a straightforward selection. Systems that need maximum graphics and compute performance should use the RTX 5070 Mobile, which delivers results comparable to desktop parts like the RTX 3070 Ti and RTX 2080 Ti. Systems that prioritize low power consumption and do not require dedicated memory or tensor core acceleration may find the Arc Pro B370 sufficient. The RTX 5070 Mobile's PCIe 5.0 x16 interface and dedicated memory make it suitable for demanding workloads, while the Arc Pro B370's integrated nature and system shared memory tie its performance to the host platform. The RTX 5070 Mobile is the stronger part by every measurable specification in the database.
