Intel Arc B390 vs NVIDIA GeForce RTX 5070 Ti Comparison

The Verdict

The database comparison between the Intel Arc B390 and the NVIDIA GeForce RTX 5070 Ti is decisively one-sided. The RTX 5070 Ti wins the only shared benchmark, 3DMark Steel Nomad (DX12), by a margin of 77.6%, scoring 6604 against the Arc B390’s 1482. The RTX 5070 Ti sits in the 86th percentile of all GPUs, while the Arc B390 lands in the 9th percentile. The RTX 5070 Ti is for desktop gamers and compute users who need discrete performance, while the Arc B390 is an integrated graphics processor (IGP) intended for portable devices where a dedicated card is not an option. The data shows no scenario where the Intel part wins a head-to-head test, so the choice is dictated by platform and power constraints, not by performance parity.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Ti wins in every measurable category from the recorded data. It wins the 3DMark Steel Nomad test by 77.6%, which is the only direct comparison available. Its average benchmark score is 49957 versus 1482 for the Arc B390, a gap of roughly 34 times. The RTX 5070 Ti’s percentile rank of 86 versus 9 means it outperforms nearly the entire database, whereas the Arc B390 outperforms only a small fraction. The NVIDIA card also has a full set of compute and graphics benchmarks, while the Intel part has just a single entry.

The Arc B390’s wins are limited to its form factor and power envelope. It is an IGP with an 80 W TDP, no power connectors, and no suggested PSU, making it suitable for portable devices where the RTX 5070 Ti’s 300 W TDP, 700 W suggested PSU, and dual-slot cooler cannot apply. The Intel part’s base clock of 300 MHz and boost of 2500 MHz show a wide dynamic range, but the performance ceiling is low. The RTX 5070 Ti’s base clock of 2295 MHz is higher than the Arc B390’s boost clock by 157 MHz, and its boost of 2452 MHz further extends the lead.

For users with a PCIe 5.0 x16 slot and a 700 W PSU, the RTX 5070 Ti delivers 16 GB of GDDR7 memory, 896.0 GB/s bandwidth, and 43.94 TFLOPS FP32. For users constrained to integrated graphics, the Arc B390 provides 7.680 TFLOPS FP32 and shared memory, but it cannot match any discrete GPU in the RTX 5070 Ti’s class. The database shows 0 wins for the Arc B390 and 1 win for the RTX 5070 Ti, making the NVIDIA part the only choice for performance-sensitive workloads. The Intel part remains viable only where its IGP form factor and low TDP are mandatory requirements.
