RX 9070 vs RX 7900 XTX: Ray Tracing Performance Compared 2026

Quick Answer

The RX 9070 closes the ray tracing gap significantly compared to previous RDNA generations, but the RX 7900 XTX still leads in raw RT performance at 4K. In South Africa where both cards sit at very different price points, the 9070 offers better RT value per rand for 1440p gaming.

Ray tracing has long been AMD's Achilles heel, but the RX 9070 changes the conversation in a meaningful way. With RDNA 4 architecture bringing hardware-accelerated RT improvements, South African gamers finally have a compelling AMD option that does not compromise heavily on visual fidelity. The question is whether the 9070 can take the fight to the 7900 XTX - a card that still retails in the R12,000-R15,000 range locally.

RDNA 4 Ray Tracing Architecture Changes

The RX 9070 is built on RDNA 4, which introduces second-generation ray accelerators paired with improved AI denoising. Each compute unit now handles ray-box intersections and ray-triangle intersections more efficiently than RDNA 3. The result is roughly 35-50% better RT throughput per compute unit compared to the 7900 XTX's RDNA 3 cores. That is a significant architectural leap. The 9070 also benefits from better BVH (Bounding Volume Hierarchy) traversal, which reduces the performance hit from dense RT scenes. In titles like Cyberpunk 2077 with path tracing, Alan Wake 2, and Metro Exodus Enhanced, the 9070 holds its own at 1440p where the 7900 XTX was previously the go-to choice for AMD gamers who wanted decent RT.

Head-to-Head Ray Tracing Benchmarks

At 1080p with ray tracing enabled, the RX 9070 and RX 7900 XTX are surprisingly close. In Cyberpunk 2077 at Ultra RT settings, the 9070 averages around 72 FPS versus the 7900 XTX's 78 FPS - a 8% difference. At 1440p that gap widens slightly, with the 7900 XTX pulling ahead by 12-15% in the most RT-heavy titles. At 4K is where the 7900 XTX's larger memory bandwidth and 24GB VRAM buffer matters most - it consistently outpaces the 9070 by 20-25% in ray traced workloads at 4K. However, with FSR 4 upscaling on the 9070, the gap narrows considerably. FSR 4 is exclusive to RDNA 4 and delivers noticeably better image quality than FSR 3.1, making the 9070 more competitive in practice than raw native benchmarks suggest.

Which Card Makes Sense for SA Gamers?

The 7900 XTX commands a significant premium in South Africa, often sitting R4,000-R6,000 above the RX 9070. For 1080p and 1440p gaming with ray tracing, the 9070's improved RDNA 4 RT performance combined with FSR 4 support means you are getting 85-90% of the RT experience at a substantially lower cost. For 4K ray tracing specifically, the 7900 XTX still justifies its premium if that is your target resolution. The 9070 is the smarter buy for most SA gamers who game at 1440p and want ray tracing without the flagship price tag.

AMD Software and Driver Maturity

One area where both cards share common ground is AMD's Adrenalin software suite. Driver stability has improved dramatically in 2025-2026, with both cards benefiting from regular optimizations. The 9070 adds Fluid Motion Frames 2 support on top of FSR 4, giving it a frame generation advantage that the 7900 XTX lacks natively. This means in RT-heavy titles, a 9070 with Fluid Motion Frames 2 enabled can actually deliver a smoother experience than a 7900 XTX at the same settings, even if the base frame rate is slightly lower.

Frequently Asked Questions

Q: Can the RX 9070 handle ray tracing in Cyberpunk 2077 at 1440p? A: Yes - at 1440p with Ultra RT settings, the RX 9070 averages around 60-72 FPS in Cyberpunk 2077 depending on scene complexity. With FSR 4 Quality mode enabled, you can push this to 90+ FPS with minimal visual compromise.

Q: Does the RX 7900 XTX still beat the 9070 in ray tracing? A: At 4K the 7900 XTX maintains a 20-25% RT performance advantage. At 1440p and below, the gap shrinks to 8-15%, and the 9070's FSR 4 support helps close that gap in real-world gaming scenarios.

Q: Is the RX 9070 worth buying over the 7900 XTX for RT gaming in South Africa? A: For 1440p ray tracing, the 9070 offers significantly better value per rand. The 7900 XTX is only clearly better value if you are gaming at 4K with RT enabled and have the budget for it.

Q: Does the RX 9070 support path tracing like the RTX 4000 series? A: The 9070 supports path tracing in titles that implement it through AMD's RT stack, but NVIDIA's dedicated RT cores still hold an advantage in fully path-traced games. The 9070 is competitive in hybrid RT implementations but not quite at RTX 4080-level path tracing performance.
