Intel Arc B370 vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the Intel Arc B370 and the NVIDIA GeForce RTX 5070 Mobile. The database lists a single 3DMark Steel Nomad DX12 score for the Intel part at 1184 points, while the NVIDIA part has a broader set of results including Geekbench OpenCL at 122238, Geekbench Vulkan at 116960, Passmark DirectX 10 at 129, DirectX 11 at 192, DirectX 12 at 93, DirectX 9 at 214, G2D at 896, G3D at 20355, and GPU compute at 8279. The average benchmark score for the Intel Arc B370 is 1184, placing it in the 5th percentile of all GPUs. The NVIDIA RTX 5070 Mobile averages 29928, placing it in the 75th percentile.

The nearest rivals for the Intel part show how close its single recorded score sits to older discrete parts. The ATI Mobility Radeon HD 5570 averages 1186, a 0.2 percent advantage over the Intel B370. The ATI Radeon HD 5770 averages 1190, 0.5 percent higher. The AMD Radeon HD 7650M averages 1192, 0.7 percent higher. The AMD FirePro M2000 averages 1168, which is 1.4 percent lower than the Intel B370. These deltas are tiny, indicating the Intel integrated part lands in the same performance neighborhood as those legacy mobile and entry desktop GPUs.

For the NVIDIA side, the nearest rivals are far more recent and powerful. The NVIDIA GeForce RTX 3070 Ti averages 29945, just 0.1 percent higher than the RTX 5070 Mobile. The RTX 2080 Ti averages 29783, which is 0.5 percent lower. The AMD Radeon RX 6800 averages 30095, 0.6 percent higher. The AMD Radeon RX 6700 averages 30433, 1.7 percent higher. The RTX 5070 Mobile thus sits within a few percent of desktop-class cards from the previous generation, a stark contrast to the Intel part's proximity to decade-old hardware.

The raw score gap is enormous. The NVIDIA part's average of 29928 is roughly 25 times the Intel part's 1184. Even the most favorable single test for NVIDIA, Passmark DirectX 9 at 214, exceeds the Intel B370's entire average by a factor of about five. The Intel B370 has no recorded wins in any head-to-head comparison; the database shows zero wins for either side, but with no shared benchmark tests, the comparative picture relies entirely on the separate averages and percentile placements.

Architecture Differences

The Intel Arc B370 uses the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process at Intel's own foundry. The NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip with Blackwell 2.0 architecture, built on a 5 nm process at TSMC. Intel's process node is smaller, but the transistor counts tell a different story: the database lists Intel's transistor count and die size as unknown, while NVIDIA's GB206 carries 21,900 million transistors on a 181 mm² die, yielding a density of 121.0M per mm².

The Intel part is an integrated graphics processor (IGP) with system-shared memory, no dedicated memory bus width, and system-dependent bandwidth. The NVIDIA part is also listed as IGP in slot width, but it has 8 GB of GDDR7 memory on a 128-bit bus with 384.0 GB/s bandwidth. The memory clock for NVIDIA is 1500 MHz with 24 Gbps effective speed, while Intel's memory clock is listed as "System Shared" with no fixed figure.

Compute resources diverge sharply. The Intel B370 has 1280 shading units, 40 texture mapping units, 20 ROPs, and 10 ray tracing cores. The NVIDIA RTX 5070 Mobile has 4608 shading units, 144 TMUs, 48 ROPs, 36 RT cores, and 144 tensor cores. The Intel part has no tensor core count listed, while NVIDIA's tensor core count is a major architectural feature for AI workloads.

Clock speeds also differ substantially. The Intel B370 runs at a base of 300 MHz and boosts to 2400 MHz. The NVIDIA part has a base of 907 MHz and a boost of 1425 MHz. Despite the Intel part's higher boost clock, its much lower shading unit count limits its throughput. Pixel rate for Intel is 48.00 GPixel/s versus NVIDIA's 68.40 GPixel/s. Texture rate is 96.00 GTexel/s versus 205.2 GTexel/s. FP32 compute is 6.144 TFLOPS for Intel versus 13.13 TFLOPS for NVIDIA. FP16 for Intel is 12.29 TFLOPS at 2:1 ratio, while NVIDIA lists 13.13 TFLOPS at 1:1 ratio, meaning Intel's FP16 advantage is only via a lossy conversion path.

Power consumption differs by a factor of two: Intel is rated at 25 W TDP, NVIDIA at 50 W TDP. Both use no power connectors and are IGP solutions. The bus interface for Intel is IGP, while NVIDIA uses PCIe 5.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The release dates are recorded as 2026-01-26 for Intel and 2025-04-14 for NVIDIA, making the NVIDIA part earlier to market. The NVIDIA predecessor is listed as GeForce 40 Mobile; Intel has no predecessor listed.

The Verdict

The data indicates a massive performance gap. The NVIDIA RTX 5070 Mobile averages 29928, which is 25 times higher than the Intel Arc B370's 1184. The nearest rival analysis confirms this separation: the RTX 5070 Mobile trades within 1.7 percent of desktop GPUs like the RTX 3070 Ti, RTX 2080 Ti, RX 6800, and RX 6700, while the Arc B370 sits within 1.4 percent of mobile and entry GPUs from the HD 5000 and 7000 series era.

The RTX 5070 Mobile also offers a more complete feature set in the database. It has a dedicated 8 GB GDDR7 memory pool with 384.0 GB/s bandwidth, 144 tensor cores, and a PCIe 5.0 x16 interface. The Arc B370 relies on system-shared memory with no fixed bandwidth and has no tensor core count recorded. The Intel part does have a lower TDP of 25 W versus 50 W, and a smaller process node at 3 nm versus 5 nm, but those advantages do not translate into benchmark wins.

The Intel part's only recorded benchmark is 3DMark Steel Nomad DX12 at 1184, placing it in the 5th percentile. The NVIDIA part has nine recorded benchmark entries spanning Geekbench, Passmark DirectX variants, G2D, G3D, and GPU compute, with its lowest score at 93 (Passmark DirectX 12) and its highest at 122238 (Geekbench OpenCL). The breadth of testing for NVIDIA versus the single test for Intel limits direct comparability, but the average scores and percentile ranks provide a clear ordering.

Where Each One Wins

The NVIDIA RTX 5070 Mobile wins on every measurable performance dimension in the database. Its shading unit count of 4608 is 3.6 times the Intel part's 1280. Its texture rate of 205.2 GTexel/s is more than double Intel's 96.00 GTexel/s. Its pixel rate of 68.40 GPixel/s exceeds Intel's 48.00 GPixel/s. Its FP32 throughput of 13.13 TFLOPS is more than double Intel's 6.144 TFLOPS. Its ray tracing core count of 36 versus 10 suggests substantially higher RT workload capability. Its memory bandwidth of 384.0 GB/s versus system-dependent bandwidth for Intel gives it a fixed, high-bandwidth advantage. Its percentile rank of 75 versus 5 places it firmly in the upper quarter of all GPUs, while the Intel part sits in the bottom 5 percent.

The Intel Arc B370 wins on power efficiency and process technology. Its TDP of 25 W is half of NVIDIA's 50 W. Its 3 nm process node is smaller than NVIDIA's 5 nm node. Its boost clock of 2400 MHz is higher than NVIDIA's 1425 MHz, though the lower shading unit count negates that advantage in throughput. Its FP16 rating of 12.29 TFLOPS at 2:1 ratio is close to NVIDIA's 13.13 TFLOPS at 1:1, but the ratio difference means Intel's FP16 requires a conversion that NVIDIA does not. The Intel part also has a later release date of 2026-01-26 versus 2025-04-14, and it has no predecessor listed, whereas NVIDIA's predecessor is GeForce 40 Mobile.

For use cases, the database suggests the RTX 5070 Mobile is suited for any scenario requiring substantial graphics throughput, compute density, or ray tracing, given its 75th percentile placement and its closeness to desktop-class rivals. The Arc B370, with its 5th percentile placement and single benchmark score below 1200, is positioned for low-power integrated graphics duties where the 25 W TDP and system-shared memory are acceptable constraints. The absence of head-to-head benchmark entries means the database does not record any direct comparison, but the separate averages and nearest rival deltas make the performance hierarchy unambiguous.
