Intel Arc B580 vs NVIDIA GeForce RTX 5070 SUPER Comparison

Head-to-Head Benchmarks

The recorded data contains a single direct head-to-head benchmark between the Intel Arc B580 and the NVIDIA GeForce RTX 5070 SUPER: the 3DMark Steel Nomad DX12 test. In this run, the Intel Arc B580 scored 3068, while the NVIDIA GeForce RTX 5070 SUPER scored 2690. That is a 14.1% advantage for the Intel part, a substantial margin in a single synthetic workload.

This result is curious because the broader benchmark database places the two cards in very different positions. The Intel Arc B580 holds a 68th percentile ranking among all GPUs, with an average benchmark score of 23021 across ten recorded tests. The NVIDIA GeForce RTX 5070 SUPER, by contrast, sits at the 18th percentile with an average score of only 2690, derived from just one recorded benchmark. The huge gap between the average scores and the head-to-head result suggests that the Steel Nomad test may be measuring something specific where the Intel architecture excels, or that the RTX 5070 SUPER's single recorded score is not representative of its overall capability.

Looking at the nearest rivals in the database clarifies the picture. The Intel Arc B580's average score of 23021 places it within 0.2% of the AMD Radeon RX 580 2048SP (23061), 0.6% above the NVIDIA GeForce RTX 2080 (22895), and 0.7% below the NVIDIA GeForce RTX 3080 (23172). These are tight margins, indicating that the B580 delivers performance roughly on par with older flagship cards from several generations back. The RTX 5070 SUPER's nearest rivals tell a very different story: its 2690 average score is just 1% above the NVIDIA Quadro K1100M (2664), 1.1% above the GeForce GT 1030 (2662), and 1.7% above the GeForce GT 440 (2645). Those are entry-level and legacy parts, which makes the 5070 SUPER's single-score database presence look anomalous.

The head-to-head delta of 14.1% is the only direct comparison available, and it favors Intel. In the Steel Nomad DX12 workload, the Arc B580 delivers noticeably higher throughput. But the database's overall averages imply that this single test may not capture the full spectrum of the RTX 5070 SUPER's performance. A 14.1% win in one benchmark does not automatically translate to a 14.1% win across all games and compute tasks, especially when the two cards' architectural profiles differ so sharply.

Where Each One Wins

Based strictly on the recorded data, the Intel Arc B580 wins the only head-to-head benchmark available. In the 3DMark Steel Nomad DX12 test, it outperforms the NVIDIA GeForce RTX 5070 SUPER by 14.1%. This is the sole direct comparison, so any broader claims about other workloads cannot be substantiated from the database.

The Intel card also shows strength across a wider range of recorded tests. Its ten benchmarks include 3DMark Steel Nomad, Geekbench OpenCL, Geekbench Vulkan, and multiple Passmark tests (DirectX 9, 10, 11, 12, G2D, G3D, and GPU compute). Its highest individual scores include 109672 in Geekbench Vulkan, 92821 in Geekbench OpenCL, and 15748 in Passmark G3D. These results suggest a broad, consistent performance profile across different API types and compute workloads.

The NVIDIA GeForce RTX 5070 SUPER, with only one recorded benchmark, has no wins in the direct comparison. Its 2690 score in Steel Nomad is its only data point. That score is lower than the Intel card's 3068 in the same test. However, the database's nearest rival data for the 5070 SUPER shows it slightly ahead of legacy parts like the GeForce GT 440 and GT 1030, with deltas of 1.7% and 1.1% respectively. This indicates that the 5070 SUPER's single recorded performance is at least above those older entries, but it does not establish any workload where it beats the Arc B580.

For use cases, the data suggests the Intel Arc B580 is the stronger choice in the 3DMark Steel Nomad workload, which is a DX12 test. The Intel card's additional benchmark coverage in Vulkan, OpenCL, and DirectX variants implies it has been exercised across a wider range of scenarios, though the database does not include comparable scores for the NVIDIA card in those same tests. Without that data, the only verifiable win belongs to Intel.

Specification Differences

The two cards differ in nearly every major specification category. The Intel Arc B580 uses the BMG-G21 chip, while the NVIDIA GeForce RTX 5070 SUPER uses the GB205 chip. Both are built on a 5 nm process at TSMC, but the transistor counts diverge substantially: the B580 has 19,600 million transistors on a 272 mm² die, while the 5070 SUPER has 31,100 million transistors on a slightly smaller 263 mm² die. This yields a transistor density of 72.1M per mm² for Intel versus 118.3M per mm² for NVIDIA.

Clock speeds also differ. The Intel card runs at a base and boost clock of 2670 MHz, while the NVIDIA card has a 2325 MHz base and 2512 MHz boost. Memory configurations are notably different: the B580 has 12 GB of GDDR6 on a 192-bit bus with 456.0 GB/s bandwidth, whereas the 5070 SUPER has 18 GB of GDDR7 on the same 192-bit bus but with 672.0 GB/s bandwidth. Memory clocks are 2375 MHz (19 Gbps effective) for Intel and 1750 MHz (28 Gbps effective) for NVIDIA.

The compute unit counts show a large gap. The B580 has 2560 shading units, 160 TMUs, 80 ROPs, 20 ray tracing cores, and no tensor cores. The 5070 SUPER has 6400 shading units, 200 TMUs, 80 ROPs, 50 ray tracing cores, and 200 tensor cores. Pixel rates are close (213.6 GPixel/s for Intel versus 201.0 GPixel/s for NVIDIA), but texture rates differ (427.2 GTexel/s versus 502.4 GTexel/s). Floating-point throughput is dramatically higher on the NVIDIA card: 32.15 TFLOPS FP32 versus 13.67 TFLOPS, and 32.15 TFLOPS FP16 (1:1) versus 27.34 TFLOPS (2:1) for Intel.

Power and physical specs diverge as well. The B580 has a 190 W TDP with a single 8-pin connector and a suggested 450 W PSU, while the 5070 SUPER has a 275 W TDP with a single 16-pin connector and no suggested PSU listed. Both are dual-slot cards, but the B580 is longer at 272 mm versus 245 mm, and thicker at 45 mm versus 40 mm. Height is identical at 115 mm. The bus interface differs: PCIe 4.0 x8 for Intel versus PCIe 5.0 x16 for NVIDIA. Display outputs are similar (1x HDMI and 3x DisplayPort) but with different versions: HDMI 2.1a and DisplayPort 2.1 for Intel, HDMI 2.1b and DisplayPort 2.1b for NVIDIA. API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Architecture Differences

The architectural split is fundamental. The Intel Arc B580 uses the Xe2-HPG architecture, part of the Battlemage generation (Arc 5). The NVIDIA GeForce RTX 5070 SUPER uses Blackwell 2.0, in the GeForce 50-series. Both are fabricated by TSMC on a 5 nm node, but the transistor density difference (72.1M versus 118.3M per mm²) indicates that NVIDIA packs far more logic into a similar die area.

The memory architecture differs in type and capacity. Intel uses GDDR6 with 12 GB and a 192-bit bus, while NVIDIA uses GDDR7 with 18 GB on the same bus width. The effective memory speed is higher on the NVIDIA card (28 Gbps versus 19 Gbps), resulting in 672.0 GB/s versus 456.0 GB/s bandwidth. This is a 47% bandwidth advantage for NVIDIA, which matters for high-resolution textures and compute workloads.

The compute architecture shows a stark difference in shader organization. The B580 has 2560 shading units and 20 ray tracing cores, with no dedicated tensor cores. The 5070 SUPER has 6400 shading units, 50 ray tracing cores, and 200 tensor cores. The FP16 ratio also differs: Intel achieves 27.34 TFLOPS via a 2:1 ratio relative to FP32, while NVIDIA achieves 32.15 TFLOPS at a 1:1 ratio. This means NVIDIA's FP16 throughput equals its FP32 throughput, whereas Intel's FP16 is double its FP32 but still lower in absolute terms.

The bus interface is another differentiator. Intel uses PCIe 4.0 x8, which limits bandwidth to the CPU compared to NVIDIA's PCIe 5.0 x16. The power delivery also reflects the performance gap: Intel draws 190 W with a single 8-pin, while NVIDIA draws 275 W with a single 16-pin. The NVIDIA card's higher power envelope aligns with its higher transistor count and shader count.

The Verdict

The recorded data points to the Intel Arc B580 as the winner in the only direct benchmark available. Its 3068 score in 3DMark Steel Nomad DX12 beats the NVIDIA GeForce RTX 5070 SUPER's 2690 by 14.1%. The Intel card also has a significantly higher database percentile (68th versus 18th) and a much larger average benchmark score (23021 versus 2690), though this is partly because the B580 has ten recorded tests while the 5070 SUPER has only one.

The specification differences strongly favor the NVIDIA card on paper. The 5070 SUPER has more than double the shading units (6400 versus 2560), 2.5 times the ray tracing cores (50 versus 20), 200 tensor cores versus none, 50% more memory (18 GB versus 12 GB), faster memory (672.0 GB/s versus 456.0 GB/s), and more than double the FP32 throughput (32.15 TFLOPS versus 13.67 TFLOPS). It also uses GDDR7, a newer memory type, and supports PCIe 5.0 x16 versus PCIe 4.0 x8.

Yet the single head-to-head benchmark contradicts those specifications. The Arc B580, despite its lower shader count and memory bandwidth, delivered a 14.1% higher score in Steel Nomad. This could indicate that the DX12 workload in that test is more sensitive to certain Intel optimizations, or that the 5070 SUPER's single recorded score is not representative of its true performance. The database shows the 5070 SUPER's nearest rivals as legacy parts like the GT 1030 and GT 440, which suggests its recorded score is unusually low for a modern GeForce 50-series card.

Who should pick which? Based strictly on the data, the Intel Arc B580 is the safer choice for the 3DMark Steel Nomad workload, as it demonstrably wins that test. It also has a broader set of recorded benchmarks, giving more confidence in its overall performance profile. The NVIDIA card's specifications indicate higher theoretical compute capability, particularly for FP32 and ray tracing, but the database does not contain any benchmark results that confirm this advantage in practice.

The data implies that the RTX 5070 SUPER's performance is severely underreported in the database, with only one test recorded. The Intel card's 14.1% head-to-head win is real but may not generalize. For users who prioritize the specific DX12 scenario in Steel Nomad, the Arc B580 is the verified choice. For those who rely on the broader specification sheet, the 5070 SUPER appears more capable on paper, but no recorded benchmark substantiates that. The database can only confirm what it measures, and it measures a clear Intel victory.
