Intel Arc B570 vs NVIDIA GeForce RTX 5070 Mobile Comparison

The Intel Arc B570 and NVIDIA GeForce RTX 5070 Mobile occupy different segments of the graphics market, and the benchmark data confirms a clear performance hierarchy between them. The RTX 5070 Mobile wins all nine head-to-head comparisons recorded in the database, with an average benchmark score of 29928 compared to the Arc B570's 20556. This places the RTX 5070 Mobile in the 75th percentile of all GPUs, while the Arc B570 sits in the 65th percentile. The data indicates a substantial overall performance gap, but the specific strengths and architectural trade-offs of each card require closer inspection.

The Verdict

The RTX 5070 Mobile is the faster GPU by every measurable metric in the database. Its average benchmark score of 29928 is 45.6% higher than the Arc B570's 20556. The mobile NVIDIA part also outperforms its nearest rival, the desktop NVIDIA GeForce RTX 3070 Ti, by a marginal 0.1% delta, while the Arc B570 nearly matches the NVIDIA GeForce RTX 3070 Mobile with a 0.1% delta. For users prioritizing raw compute and modern API performance, the RTX 5070 Mobile is the definitive choice according to the recorded data.

The Arc B570, despite losing every head-to-head test, remains a competitive desktop option within its own performance tier. Its nearest rivals include the Intel Arc A750 with a delta of -0.1% and the AMD Radeon R9 M390X with a delta of -0.5%, showing that it clusters closely with those products. The desktop card draws 150 W, uses a dual-slot cooler with a single 8-pin power connector, and requires a 450 W suggested power supply, whereas the RTX 5070 Mobile is an IGP with no power connectors and a 50 W TDP. The desktop Arc B570 is designed for full-size systems, while the RTX 5070 Mobile is built for portable devices, and the data reflects that the mobile chip delivers substantially higher performance despite its constrained power envelope.

Where Each One Wins

The head-to-head results show a clean sweep for the NVIDIA GeForce RTX 5070 Mobile across all nine benchmark tests. The largest win for the RTX 5070 Mobile comes in PassMark DirectX 10, where it scores 129 against the Arc B570's 65, a 49.6% advantage. The second biggest gap is in PassMark DirectX 11, with the NVIDIA part scoring 192 versus 118, a 38.5% delta. The PassMark G3D test shows a 30.3% lead for the RTX 5070 Mobile, with scores of 20355 and 14195 respectively. These results indicate that the RTX 5070 Mobile dominates in legacy DirectX workloads and general 3D rendering.

The Arc B570 does not win any individual benchmark, but its closest relative performance comes in PassMark GPU Compute, where it trails by only 12.1% with scores of 7281 versus 8279. The Geekbench OpenCL test shows a 31.7% deficit for the Arc B570, while the Geekbench Vulkan test shows a 17.2% deficit. The PassMark DirectX 9 and DirectX 12 tests show deficits of 23.4% and 22.6% respectively. The PassMark G2D test, which measures 2D graphics performance, shows a 26.2% gap in favor of the RTX 5070 Mobile. No scenario exists in the recorded data where the Arc B570 takes the lead, so use-case selection depends entirely on whether the user accepts lower performance for a desktop form factor or chooses the mobile solution for higher output.

Architecture Differences

The two GPUs stem from fundamentally different design philosophies. The Intel Arc B570 uses the BMG-G21 chip built on the Xe2-HPG architecture, part of the Battlemage generation within the Arc 5 family. It is fabricated on a 5 nm process at TSMC, with 19,600 million transistors spread across a 272 mm² die, resulting in a transistor density of 72.1 million per mm². The NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip based on Blackwell 2.0 architecture from the GeForce 50-series Mobile generation. It also uses a 5 nm TSMC process but packs 21,900 million transistors into a smaller 181 mm² die, achieving a higher density of 121.0 million transistors per mm².

The core configurations differ significantly. The Arc B570 has 2304 shading units, 144 TMUs, and 80 ROPs, along with 18 ray tracing cores. The RTX 5070 Mobile has 4608 shading units, double the Arc's count, with 144 TMUs and 48 ROPs, plus 36 ray tracing cores and 144 tensor cores. The RTX 5070 Mobile's pixel rate is 68.40 GPixel/s and its texture rate is 205.2 GTexel/s, while the Arc B570 achieves 200.0 GPixel/s and 360.0 GTexel/s. The Arc B570's higher texture rate stems from its 144 TMUs operating at a 2500 MHz clock, versus the RTX 5070 Mobile's 144 TMUs at a 1425 MHz boost clock. The FP32 throughput favors the NVIDIA part at 13.13 TFLOPS versus 11.52 TFLOPS. FP16 performance diverges sharply: the Arc B570 delivers 23.04 TFLOPS with a 2:1 ratio, while the RTX 5070 Mobile delivers 13.13 TFLOPS at a 1:1 ratio, meaning the Intel card has a dedicated advantage in half-precision workloads.

Memory subsystems also differ. The Arc B570 uses 10 GB of GDDR6 on a 160-bit bus, producing 380.0 GB/s of bandwidth. The RTX 5070 Mobile uses 8 GB of GDDR7 on a 128-bit bus, yielding 384.0 GB/s. The NVIDIA part has slightly higher bandwidth despite a smaller bus width, thanks to faster memory running at 24 Gbps effective versus 19 Gbps effective. The interface differs as well: the Arc B570 uses PCIe 4.0 x8, while the RTX 5070 Mobile uses PCIe 5.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.
