Intel Arc B570 vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

The Verdict

The benchmark data separates these two GPUs cleanly. The NVIDIA GeForce RTX 5070 Ti Mobile wins all nine head-to-head tests recorded in the database, with deltas ranging from 27.9% to 57% in its favor. Its average benchmark score of 35435 places it at the 80th percentile of all GPUs, while the Intel Arc B570 averages 20556 and sits at the 65th percentile. The RTX 5070 Ti Mobile's nearest rivals are the NVIDIA Quadro GV100 (0.2% ahead) and the AMD Radeon Pro Duo (1.2% ahead), which shows it competes in a higher performance class. The Arc B570, by comparison, trades positions with the NVIDIA GeForce RTX 3070 Mobile (0.1% ahead) and the Intel Arc A750 (0.1% behind). The data indicates the NVIDIA part is the stronger choice for any workload where raw compute and graphics throughput matter, including DirectX 12, Vulkan, and OpenCL tasks. The Intel part remains a functional alternative for systems where its lower thermal envelope and simpler power delivery are priorities, but it does not match NVIDIA's recorded output in any measured test. The Verdict: the RTX 5070 Ti Mobile dominates on performance metrics; the Arc B570 is the fallback for constrained mobile or compact builds.

Architecture Differences

The two GPUs use different architectures, node designs, and feature sets. The Intel Arc B570 uses the Xe2-HPG architecture on the BMG-G21 chip, belonging to the Battlemage (Arc 5) generation. It is built on a 5 nm process at TSMC, with 19,600 million transistors on a 272 mm² die, giving a transistor density of 72.1M per mm². The NVIDIA GeForce RTX 5070 Ti Mobile uses the Blackwell 2.0 architecture on the GB205 chip, part of the GeForce 50 Mobile generation. It also uses a 5 nm TSMC process, but packs 31,100 million transistors into a 263 mm² die, achieving a higher density of 118.3M per mm².

The shading resources differ substantially. The RTX 5070 Ti Mobile carries 5888 shading units, 184 texture mapping units, 80 ROPs, 46 ray tracing cores, and 184 tensor cores. The Arc B570 has 2304 shading units, 144 TMUs, 80 ROPs, and 18 ray tracing cores, with no tensor core count listed in the database. The NVIDIA part also has a different FP16 implementation: it delivers 17.04 TFLOPS FP16 at a 1:1 ratio, meaning FP16 and FP32 throughput are equal. The Intel part delivers 23.04 TFLOPS FP16 at a 2:1 ratio, doubling its FP32 rate of 11.52 TFLOPS. The RTX 5070 Ti Mobile reaches 17.04 TFLOPS FP32.

Memory architecture also differs. The Arc B570 uses 10 GB of GDDR6 on a 160-bit bus, producing 380.0 GB/s of bandwidth. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 on a 192-bit bus, producing 672.0 GB/s. The NVIDIA part has a lower base clock of 847 MHz and a boost clock of 1447 MHz, while the Intel part runs at a flat 2500 MHz for both base and boost. The NVIDIA memory clock is 1750 MHz (28 Gbps effective), compared to the Intel's 2375 MHz (19 Gbps effective). The RTX 5070 Ti Mobile's higher bandwidth and greater memory capacity give it a structural advantage in bandwidth-heavy scenes, even though its core clocks are lower.

The power and physical profiles are nearly opposite. The Arc B570 has a TDP of 150 W, uses a dual-slot cooler, requires a single 8-pin power connector, and needs a suggested 450 W PSU. It is a PCIe 4.0 x8 card with 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs, measuring 272 mm in length and 115 mm in height. The RTX 5070 Ti Mobile is an IGP (integrated graphics processor) with a 60 W TDP, no power connectors, no suggested PSU, and a PCIe 5.0 x16 interface. Its display outputs are listed as portable device dependent, and it has no recorded dimensions. The NVIDIA part is designed for mobile integration, while the Intel part is a discrete add-in card.

Head-to-Head Benchmarks

The RTX 5070 Ti Mobile wins every recorded head-to-head test, but the margins vary by workload. The largest gap appears in the Passmark DirectX 10 test, where the NVIDIA part scores 151 against the Intel's 65, a 57% difference. The Passmark DirectX 11 test shows the NVIDIA part at 237 versus 118, a 50.2% lead. In the Passmark DirectX 9 test, the NVIDIA part scores 259 against 164, a 36.7% advantage. The Passmark DirectX 12 test shows the smallest margin in the DirectX family: 102 versus 72, a 29.4% lead. These results indicate that the NVIDIA part maintains a consistent advantage across legacy and modern DirectX APIs, with the largest gap in the older DX10 path.

The compute-oriented tests also favor NVIDIA. In Geekbench OpenCL, the RTX 5070 Ti Mobile scores 143870 versus 83514, a 42% difference. In Geekbench Vulkan, it scores 139213 versus 96844, a 30.4% lead. The Passmark GPU Compute test shows 10101 versus 7281, a 27.9% difference, the smallest margin of any recorded test. The Passmark G3D test, a general 3D graphics benchmark, shows 24004 versus 14195, a 40.9% gap. The Passmark G2D test shows 981 versus 661, a 32.6% difference.

The pattern is clear: the RTX 5070 Ti Mobile leads by roughly 28% to 57% across all nine tests, with compute and modern graphics APIs showing the smaller margins and older DirectX paths showing the larger ones. The Intel Arc B570's closest result is the Passmark GPU Compute test at 27.9% behind, and its worst is the Passmark DirectX 10 test at 57% behind. The database records zero wins for the Intel part in this comparison.
