Intel Arc B370 vs NVIDIA GeForce RTX 5070 SUPER Comparison

Head-to-Head Benchmarks

The only recorded comparison in the database is the 3DMark Steel Nomad DX12 test, and it is a decisive one. The NVIDIA GeForce RTX 5070 SUPER scores 2690, while the Intel Arc B370 scores 1184. That is a delta of -56%, meaning the Intel part trails by more than half in raw 3DMark performance. The RTX 5070 SUPER wins the sole head-to-head benchmark outright, and the data shows no test where the Arc B370 comes out ahead.

Looking at the percentile rankings, the gap is equally stark. The RTX 5070 SUPER sits in the 18th percentile of all GPUs in the database, while the Arc B370 sits in the 5th percentile. That places the NVIDIA card well above the vast majority of recorded hardware, while the Intel integrated part sits near the lower end of the distribution. The nearest rivals for the RTX 5070 SUPER are the NVIDIA Quadro K1100M at 2664, the GeForce GT 1030 at 2662, the Intel Arc Pro B50 at 2660, and the GeForce GT 440 at 2645. The RTX 5070 SUPER leads all of them, with deltas of 1% to 1.7%. For the Arc B370, the nearest rivals are the ATI Mobility Radeon HD 5570 at 1186, the ATI Radeon HD 5770 at 1190, the AMD Radeon HD 7650M at 1192, and the AMD FirePro M2000 at 1168. The Arc B370 trails the first three by 0.2% to 0.7% and leads the FirePro M2000 by 1.4%. In other words, the Arc B370 is competitive with a cluster of older discrete and mobile parts from over a decade ago, while the RTX 5070 SUPER sits in a completely different performance class.

The delta of -56% is the single most informative number in this comparison. It is not a close race, and it is not a case where one card wins in some workloads and loses in others. The 3DMark Steel Nomad DX12 benchmark is a modern DirectX 12 test, and the RTX 5070 SUPER more than doubles the Arc B370's score. The average benchmark score in the database reflects the same picture: 2690 for the NVIDIA card versus 1184 for the Intel part.

The Verdict

The data is unambiguous. The NVIDIA GeForce RTX 5070 SUPER is the faster GPU by a wide margin, with a 3DMark Steel Nomad DX12 score of 2690 versus 1184 for the Intel Arc B370. Anyone choosing between these two strictly on performance should select the RTX 5070 SUPER. The percentile ranking confirms this: the RTX 5070 SUPER is in the 18th percentile of all GPUs, whereas the Arc B370 is in the 5th percentile.

The Intel Arc B370 is an integrated graphics processor with a 25 W TDP, built for portable devices, and its benchmark score places it alongside the ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, and AMD Radeon HD 7650M. Those are all parts from an older generation, and the Arc B370 trades blows with them within a range of -0.7% to +1.4%. It is not a part designed to compete with a dual-slot, 275 W discrete GPU like the RTX 5070 SUPER. The RTX 5070 SUPER uses a 16-pin power connector, requires a dual-slot cooler, and measures 245 mm in length. The Arc B370 has no power connectors and no slot width, as it is an IGP.

The verdict from the recorded data is simple: the RTX 5070 SUPER is the only choice for anyone who needs the performance shown in the 3DMark result. The Arc B370 is only relevant in systems where an integrated GPU is required and where the comparison against the RTX 5070 SUPER is not applicable.

Where Each One Wins

The RTX 5070 SUPER wins the only benchmark recorded in the database. It also wins on every measurable specification that affects raw performance. It has 6400 shading units versus 1280, 200 texture mapping units versus 40, 80 render output units versus 20, 50 ray tracing cores versus 10, and 200 tensor cores versus none listed for the Arc B370. Its FP32 throughput is 32.15 TFLOPS versus 6.144 TFLOPS. Its pixel rate is 201.0 GPixel/s versus 48.00 GPixel/s, and its texture rate is 502.4 GTexel/s versus 96.00 GTexel/s. The RTX 5070 SUPER also has 18 GB of GDDR7 memory on a 192-bit bus with 672.0 GB/s of bandwidth, while the Arc B370 uses system shared memory with system dependent bandwidth.

The Intel Arc B370 does not win in any recorded benchmark, but it does have advantages in power and integration. Its TDP is 25 W versus 275 W for the RTX 5070 SUPER. It is an IGP, meaning it requires no separate slot, no power connectors, and no dedicated cooling solution. The RTX 5070 SUPER is a dual-slot card with a 16-pin connector and a 245 mm length. For systems where power draw and physical footprint are the priority, the Arc B370 is the lighter option, but that is not a performance win.

The use-case split is clear from the data. The RTX 5070 SUPER is for desktop systems where maximum 3DMark performance is the goal and where 275 W of power draw is acceptable. The Arc B370 is for portable devices where the GPU is integrated into the chip and where performance is secondary to the 25 W power envelope.
