RTX 5070 vs Intel Arc B580: Ray Tracing Performance Compared 2026

Quick Answer

The RTX 5070 dramatically outperforms the Intel Arc B580 in ray tracing across all resolutions in 2026. The RTX 5070 uses fourth-generation RT cores and DLSS 4 to sustain high frame rates in ray-traced titles, while the Arc B580 offers entry-level ray tracing capability at a significantly lower price point. These cards serve different segments of the SA market.

Ray tracing performance comparisons in 2026 are increasingly relevant as more titles ship with path tracing and full RT implementations as the expected visual standard. The RTX 5070 and Intel Arc B580 sit at opposite ends of the mid-range spectrum in terms of price and capability, with the B580 targeting the budget-to-mid segment and the RTX 5070 positioned as a mainstream high-performance option. In the South African market, where the RTX 5070 typically retails between R18,000 and R22,000 and the Arc B580 sits in the R5,500 to R7,500 range, the price gap alone defines their target audiences.

Ray Tracing Architecture Differences

NVIDIA's RTX 5070 uses Blackwell architecture with fourth-generation RT cores that process ray-box and ray-triangle intersections in dedicated hardware at substantially higher throughput than previous generations. The card has 48 RT cores and leverages DLSS 4 with Multi Frame Generation to maintain playable frame rates even in path-traced workloads. Intel's Arc B580 uses Xe2 architecture (Battlemage) with dedicated ray tracing units, a genuine improvement over the first-generation Alchemist RT implementation. The B580 is capable of running ray tracing in most supported games but lacks the raw BVH traversal throughput to handle full path tracing without significant frame rate compromise.

In a title like Cyberpunk 2077 with path tracing enabled at 1080p, the RTX 5070 with DLSS 4 Quality mode sustains 60-80 FPS, while the Arc B580 with XeSS drops to 25-40 FPS in the same scenario. At 1440p with standard ray tracing (not path tracing), the RTX 5070 averages 70-90 FPS and the Arc B580 averages 30-50 FPS depending on the title. For rasterised workloads without RT, the performance gap narrows significantly - the B580 punches well above its price in standard rendering.

Which Titles Expose the Gap Most

Path tracing titles are where the RTX 5070 pulls furthest ahead. Games like Alan Wake 2, Cyberpunk 2077 with RT Overdrive, and Indiana Jones and the Great Circle running full ray tracing showcase the difference dramatically. The B580 struggles to maintain 30 FPS in these scenarios at 1440p, while the RTX 5070 handles them smoothly with upscaling. In games with selective RT features - shadows only, ambient occlusion only, or reflections only - the B580 performs considerably better and offers a reasonable RT experience at 1080p. For SA gamers who primarily play competitive titles with no RT, the B580 is a compelling value choice.

DLSS 4 vs XeSS: The Upscaling Factor

Both cards rely on AI-based upscaling to make ray tracing practical. DLSS 4 on the RTX 5070 is the current benchmark - Multi Frame Generation can multiply output frame rates 2-3x with strong image quality. XeSS 2 on the Arc B580 has improved meaningfully with Battlemage and offers acceptable image quality at Quality and Balanced presets, but it doesn't match DLSS 4's temporal stability or ghosting resistance. For the RTX 5070, upscaling essentially unlocks path tracing as a daily-driver visual mode. For the B580, XeSS makes standard RT features practical but doesn't rescue full path tracing workloads.

Value Assessment for the SA Market

For SA buyers, the decision comes down to what you actually play and what you're willing to spend. If ray tracing in AAA single-player titles is important to you and your budget allows it, the RTX 5070 at around R20,000 is a strong investment that handles current and near-future RT demands. If you're primarily a competitive or esports player who wants ray tracing as an occasional option rather than a default, the Arc B580 at R6,500 represents exceptional value per frame in standard rendering and adequate RT capability in less demanding implementations.

Frequently Asked Questions

Q: Can the Intel Arc B580 run ray tracing in 2026 games? A: Yes, the Arc B580 supports hardware ray tracing and can run most RT features in modern games, particularly at 1080p. Full path tracing is impractical due to performance constraints, but selective RT features like shadows and reflections work well.

Q: Is the RTX 5070 worth the price premium over the Arc B580 for ray tracing? A: For players who prioritise ray tracing quality and want path tracing to be a real option, yes. For standard gaming and moderate RT use, the gap in value is significant enough that the B580 at its price point makes more sense for budget-conscious SA buyers.

Q: Does the Arc B580 support DLSS? A: No. The Arc B580 supports XeSS (Intel's upscaling), which is compatible with a wider range of games than DLSS. DLSS is exclusive to NVIDIA hardware. XeSS is also compatible on NVIDIA and AMD GPUs in games that support it.

Q: How much VRAM does each card have? A: The RTX 5070 has 12GB GDDR7, while the Arc B580 has 12GB GDDR6. Both have the same VRAM capacity, though the RTX 5070's GDDR7 provides significantly higher bandwidth, which benefits ray tracing workloads.
