Intel Arc B370 vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

The Verdict

The database places these two mobile graphics processors at opposite ends of the performance spectrum. The Intel Arc B370 sits at the 5th percentile of all GPUs, while the NVIDIA GeForce RTX 5070 Ti Mobile reaches the 80th percentile. The Arc B370 has a single recorded benchmark score of 1184 in 3DMark Steel Nomad DX12, whereas the RTX 5070 Ti Mobile averages 35435 across multiple tests. The delta is enormous: the NVIDIA part outperforms the Intel part by roughly 30x in raw aggregate score. The RTX 5070 Ti Mobile is clearly the choice for demanding workloads, particularly ray tracing and high-resolution gaming. The Arc B370, with its 25 W TDP and integrated design, suits ultra-portable, low-power systems where basic 3D acceleration is sufficient. The data does not support any scenario where the Arc B370 competes with the RTX 5070 Ti Mobile in compute-heavy tasks; it is a supplementary GPU for thin-and-light devices.

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark runs between these two GPUs. Instead, recorded measurements come from separate test suites. The Arc B370 has one entry: 3DMark Steel Nomad DX12 with a score of 1184. The RTX 5070 Ti Mobile has nine entries across Geekbench and Passmark tests. Its Geekbench OpenCL score is 143870, and its Geekbench Vulkan score is 139213. Passmark results for the NVIDIA part are 24004 in G3D, 10101 in GPU compute, 981 in G2D, 259 in DirectX 9, 237 in DirectX 11, 151 in DirectX 10, and 102 in DirectX 12.

Comparing the only overlapping metric category, the RTX 5070 Ti Mobile's Passmark G3D score of 24004 dwarfs the Arc B370's 3DMark score of 1184, though these are different test suites and not directly comparable. The percentile ranking tells the story: 5th versus 80th. The RTX 5070 Ti Mobile's nearest rivals in the database are the NVIDIA Quadro GV100 (avg score 35520, delta -0.2%), AMD Radeon Pro Duo (35860, delta -1.2%), NVIDIA A2 (34690, delta 2.1%), and NVIDIA T1000 (36289, delta -2.4%). The Arc B370's nearest rivals are all older or lower-tier parts: ATI Mobility Radeon HD 5570 (1186, delta -0.2%), ATI Radeon HD 5770 (1190, delta -0.5%), AMD Radeon HD 7650M (1192, delta -0.7%), and AMD FirePro M2000 (1168, delta 1.4%).

The RTX 5070 Ti Mobile sits within 2.4% of its closest competitors, indicating it is positioned among capable desktop-class workstation GPUs. The Arc B370 sits within 1.4% of GPUs from the early 2010s era. The performance gap between the two is not marginal; it spans multiple generations of GPU capability.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Ti Mobile wins in every measured performance category. Its 17.04 TFLOPS FP32 throughput, 115.8 GPixel/s pixel rate, and 266.2 GTexel/s texture rate all exceed the Intel Arc B370's figures of 6.144 TFLOPS, 48.00 GPixel/s, and 96.00 GTexel/s. The 12 GB GDDR7 memory with 672.0 GB/s bandwidth provides dedicated high-speed storage for textures and geometry, which the system-shared memory of the Arc B370 cannot match. The 46 ray tracing cores and 184 tensor cores give the RTX 5070 Ti Mobile substantial headroom for hardware-accelerated ray tracing and AI-based features like DLSS. Its 80th percentile ranking places it among the top quarter of all GPUs in the database.

The Intel Arc B370 wins in efficiency-focused metrics. Its 25 W TDP is less than half of the RTX 5070 Ti Mobile's 60 W. It has a higher boost clock relative to its base clock: 2400 MHz versus 300 MHz, an 8x multiplier, compared to the NVIDIA part's 1447 MHz versus 847 MHz, a 1.7x multiplier. The Arc B370 is an IGP, meaning it is integrated into the processor package and requires no separate power delivery or PCIe connection. This makes it suitable for compact devices where the RTX 5070 Ti Mobile's 60 W TDP and discrete design would be impractical. The Arc B370's nearest rivals are all GPUs with average scores between 1168 and 1192, meaning it performs in line with legacy discrete parts from over a decade ago. For basic 2D desktop acceleration, video decode, and light 3D workloads, the Arc B370 delivers adequate performance within a minimal power envelope.

The specification table shows a clear generational and market-tier separation. The Intel part uses a more advanced 3 nm process but implements a far smaller GPU with fewer execution resources. The NVIDIA part uses a larger 5 nm die with 31.1 billion transistors and more than 4.5x the shading units. The RTX 5070 Ti Mobile also carries a 60 W TDP, which is high for mobile parts but reflects its performance tier.

Both GPUs share identical API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both have no power connectors and are listed as IGP slot width, though the NVIDIA part uses a PCIe 5.0 x16 bus interface. Display outputs for both are portable device dependent. Neither has a recorded launch MSRP in the database. The production status for both is Active.
