Head-to-Head Benchmarks

The database contains no shared benchmark entries between the Intel Arc B370 and the NVIDIA GeForce RTX 4090 Mobile. The head-to-head benchmark list is empty, and neither GPU records a win against the other. This means direct comparison must rely on average scores and percentile rankings.

The Arc B370 has a single recorded benchmark: 3DMark Steel Nomad DX12, scoring 1184. This places it at the 5th percentile of all GPUs. Its nearest rivals are all older or lower-end parts. The ATI Mobility Radeon HD 5570 scores 1186, just 0.2% higher. The ATI Radeon HD 5770 scores 1190, 0.5% higher. The AMD Radeon HD 7650M scores 1192, 0.7% higher. The AMD FirePro M2000 scores 1168, which is 1.4% lower than the Arc B370.

The RTX 4090 Mobile has a much richer benchmark profile. It scores 180831 in Geekbench OpenCL and 170774 in Geekbench Vulkan. In Passmark tests, it scores 173 in DirectX 10, 262 in DirectX 11, 107 in DirectX 12, 310 in DirectX 9, 984 in G2D, 27212 in G3D, and 12347 in GPU compute. Its average benchmark score is 43667.

The percentile gap is stark. The Arc B370 sits at the 5th percentile, while the RTX 4090 Mobile sits at the 84th percentile. The RTX 4090 Mobile's nearest rivals are professional and high-end parts.

The Verdict

The data indicates a complete mismatch. The NVIDIA GeForce RTX 4090 Mobile dominates the Intel Arc B370 across every measurable metric in the database. The RTX 4090 Mobile's average benchmark score of 43667 is about 36.9 times higher than the Arc B370's 1184. The percentile rankings confirm this: 84th percentile versus 5th percentile.

The RTX 4090 Mobile is designed for high-end portable gaming and compute workloads. Its 9728 shading units, 304 tensor cores, 76 RT cores, and 16 GB of GDDR6 memory with 576.0 GB/s bandwidth place it among the top 16% of all GPUs. Its nearest rivals include the RTX A6000 and Quadro M6000, both professional-class parts.

The Intel Arc B370 is an integrated graphics solution with system shared memory. Its 1280 shading units and 25 W TDP indicate a low-power design for basic graphics tasks. Its nearest rivals are older discrete parts like the ATI Mobility Radeon HD 5570 and AMD Radeon HD 7650M, which are from a previous hardware generation.

Users requiring high frame rates, ray tracing performance, or compute acceleration should rely on the RTX 4090 Mobile. Users needing basic display output and light graphics acceleration in a low-power integrated package would find the Arc B370 sufficient. The RTX 4090 Mobile is not a competitor to the Arc B370; it is in a different performance class entirely.

Where Each One Wins

The Intel Arc B370 wins in power efficiency and integration. Its 25 W TDP is one-fifth of the RTX 4090 Mobile's 120 W. It uses system shared memory, eliminating the need for dedicated VRAM. Its IGP bus interface means it is built into the processor package, requiring no separate slot. The 3 nm process node is smaller than the RTX 4090 Mobile's 5 nm node, which can improve power density.

The NVIDIA GeForce RTX 4090 Mobile wins in every performance category. Its average benchmark score is 36.9 times higher. Its 84th percentile ranking versus the Arc B370's 5th percentile shows a massive gap in overall capability. The RTX 4090 Mobile has 7.6 times more shading units, 7.6 times more TMUs, 5.6 times more ROPs, and 7.6 times more RT cores.

The RTX 4090 Mobile wins in memory performance. It has 16 GB of dedicated GDDR6 memory with 576.0 GB/s bandwidth. The Arc B370 relies on system shared memory with system dependent bandwidth. The RTX 4090 Mobile's FP32 output of 32.98 TFLOPS is 5.4 times higher than the Arc B370's 6.144 TFLOPS.

The RTX 4090 Mobile wins in feature set. It includes 304 tensor cores for AI acceleration, which the Arc B370 lacks entirely. The RTX 4090 Mobile's FP16 performance is 32.98 TFLOPS at a 1:1 ratio, while the Arc B370's FP16 is 12.29 TFLOPS at a 2:1 ratio, meaning the RTX 4090 Mobile maintains full throughput at half precision.

The Arc B370 wins in portability constraints. Its lower TDP allows thinner and lighter device designs with less thermal management. The RTX 4090 Mobile requires substantially more power delivery and cooling. The Arc B370's 2400 MHz boost clock is higher than the RTX 4090 Mobile's 1695 MHz, though this does not compensate for the massive difference in compute units.

For users prioritizing battery life and minimal heat in a compact device, the Arc B370 is the appropriate choice. For users prioritizing graphics performance, ray tracing, AI compute, or high-resolution gaming, the RTX 4090 Mobile is the only option that meets those requirements based on the recorded data.
