Users requiring sustained 3D performance should select the B570; users whose primary constraint is an integrated form factor with no expansion slot will find the B370's capabilities in line with the data.

Where Each One Wins

The B570 wins the only available head-to-head benchmark, 3DMark Steel Nomad DX12, with a score of 2649 versus 1184 for the B370. This is a 55.3% margin, a decisive advantage. The B570's victory extends across all other recorded benchmark categories, though the B370 has no entries for those tests.

The B370's sole recorded benchmark is the 3DMark Steel Nomad DX12 test. Its score of 1184 places it within a narrow band of legacy discrete and mobile GPUs. The ATI Mobility Radeon HD 5570 scores 1186, the ATI Radeon HD 5770 scores 1190, and the AMD Radeon HD 7650M scores 1192. The AMD FirePro M2000 trails at 1168. The B370 is therefore competitive with a specific class of older parts, but it has no presence in the other benchmark suites.

The B570 has a much broader benchmark footprint. It records scores across 3DMark, Geekbench OpenCL, Geekbench Vulkan, and multiple Passmark tests. In Geekbench OpenCL it scores 83514, in Geekbench Vulkan it scores 96844. Passmark results include DirectX 9 at 164, DirectX 10 at 65, DirectX 11 at 118, DirectX 12 at 72, G2D at 661, G3D at 14195, and GPU Compute at 7281. These results indicate a wide-ranging capability profile, with the G3D score being the most substantial.

The data shows no benchmark category where the B370 wins. The B570 holds a single victory in the head-to-head comparison, and the B370 has zero wins across all recorded tests. For compute-heavy workloads such as OpenCL or Vulkan, the B570's results are orders of magnitude higher, though no direct B370 comparison exists in those tests.

Head-to-Head Benchmarks

The database contains one direct comparison between the two parts: 3DMark Steel Nomad DX12. The Intel Arc B570 scores 2649, while the Intel Arc B370 scores 1184. The delta is 55.3% in favor of the B570, which is a substantial margin for a single benchmark. This test exercises DX12 rendering workloads and is a strong indicator of modern game performance.

The B370's score of 1184 falls into a narrow performance band. Its nearest rival, the ATI Mobility Radeon HD 5570, scores 1186, a 0.2% difference. The ATI Radeon HD 5770 and AMD Radeon HD 7650M are 0.5% and 0.7% ahead respectively. The AMD FirePro M2000 sits 1.4% behind. These deltas are small, indicating that the B370's performance is well characterized by the database and that it competes with a specific class of older hardware.

The B570's 3DMark score of 2649 places it in a different competitive tier. Its nearest rival, the NVIDIA GeForce RTX 3070 Mobile, averages 20534, which is 0.1% behind the B570's average of 20556. The Intel Arc A750 averages 20582, 0.1% ahead. The NVIDIA Quadro M4000M is 0.4% behind at 20480, and the AMD Radeon R9 M390X is 0.5% ahead at 20662.

Beyond the head-to-head test, the B570 has additional benchmark results that the B370 lacks entirely. The B570's Geekbench Vulkan score of 96844 and OpenCL score of 83514 indicate strong compute performance. Its Passmark G3D score of 14195 is the highest among its Passmark entries, while G2D scores 661. The DirectX 9 score of 164 is the highest among its legacy DirectX tests, with DirectX 11 at 118, DirectX 12 at 72, and DirectX 10 at 65. GPU Compute scores 7281.

The B370 has no entries for these tests, so no direct comparison is possible. The data shows the B570 winning the single recorded head-to-head test, and the B370 winning none of the recorded head-to-head benchmarks. The B570's broader benchmark presence also indicates a more versatile profile, though the B370's integrated nature means it will appear in systems where no discrete option exists.

Specification Differences
