RX 9070 XT vs RX 7700 XT: Ray Tracing Performance Compared 2026

Quick Answer

The RX 9070 XT delivers substantially better ray tracing performance than the RX 7700 XT in 2026, thanks to AMD's updated RDNA 4 architecture with dedicated hardware ray accelerators that close much of the ray tracing gap with competing GPU lines.

Architecture Differences That Drive Ray Tracing Performance

The core reason the RX 9070 XT outperforms the RX 7700 XT in ray tracing scenarios comes down to architectural improvements between RDNA 3 and RDNA 4. The RX 7700 XT was built on RDNA 3, which improved AMD's ray tracing hardware over previous generations but still lagged behind competitors in complex ray tracing workloads - particularly in titles with multiple simultaneous ray tracing effects like reflections, shadows, and ambient occlusion all active at once.

The RX 9070 XT, built on RDNA 4, introduces a substantially revised ray tracing implementation. AMD doubled the ray accelerator count per Compute Unit in RDNA 4 and improved the efficiency with which those accelerators handle BVH (Bounding Volume Hierarchy) traversal - the mathematical operation at the heart of real-time ray tracing. The result is that RDNA 4 can process ray intersection tests significantly faster than RDNA 3 at equivalent hardware costs, translating directly into higher frame rates when ray tracing is enabled in demanding scenes.

Beyond raw acceleration improvements, the RX 9070 XT benefits from a larger shader array and higher memory bandwidth. Ray tracing is both compute-intensive and memory-bandwidth-intensive, because each ray traced needs to query scene geometry data that must be fed from VRAM. The RX 9070 XT's memory configuration handles this feeding more efficiently than the 7700 XT's setup, reducing the frame rate penalty incurred when enabling ray tracing in typical game scenarios.

Real-World Ray Tracing Frame Rates: What SA Gamers Can Expect

In practice, the ray tracing performance gap between these two cards shows most clearly in titles with aggressive path tracing or complex hybrid ray tracing implementations. In games like Cyberpunk 2077 with ray tracing on and AMD's upscaling (FSR) active, the RX 9070 XT maintains playable frame rates at 1440p where the RX 7700 XT struggles to hold above 40fps with the same settings.

For titles with lighter ray tracing implementations - ambient occlusion only, or limited shadow ray tracing - the gap between the two cards narrows considerably. In these scenarios, the RX 7700 XT can still deliver enjoyable experiences, particularly at 1080p where the absolute frame rate is higher and the RT overhead is proportionally smaller. South African gamers who primarily play older titles or games that use ray tracing sparingly will see less practical benefit from upgrading to the 9070 XT specifically for ray tracing.

AMD's FSR 4, available on RDNA 4 architecture, provides a meaningful uplift for 9070 XT owners. The AI-accelerated upscaling in FSR 4 (which requires RDNA 4 hardware for full functionality) recovers frame rates lost to ray tracing more effectively than FSR 3 running on the 7700 XT. This makes the 9070 XT's effective ray tracing performance at a given resolution even stronger when upscaling is factored in, widening the practical gap between the two cards in 2026 titles that support FSR 4.

Price and Value Considerations in the South African Market

For SA buyers, the price difference between the RX 7700 XT and RX 9070 XT in Rands is a significant factor. The 9070 XT commands a premium that reflects its newer architecture and stronger performance position. Whether that premium is justified depends heavily on how much ray tracing matters to you in your current gaming library.

If your primary titles are esports games - CS2, Valorant, Apex Legends, Dota 2 - ray tracing is largely irrelevant because these games prioritise high frame rates over visual fidelity, and neither card runs ray tracing in those titles by default. The 7700 XT at a lower price point makes more financial sense for this gaming profile. But if you play single-player narrative games that increasingly use RT as a core visual feature - like the latest open-world RPGs and action-adventure titles - the 9070 XT's ray tracing capability provides a noticeably better visual experience that will remain relevant for more of the cards' usable life.

South African rand pricing also fluctuates with exchange rates, making the value calculus dynamic. At periods when the rand is weaker against the dollar or euro, the premium between these two cards widens in absolute rand terms, which can shift the value proposition further toward the 7700 XT for budget-conscious buyers. Check current local pricing before committing, as the relative gap can change meaningfully from quarter to quarter.

Frequently Asked Questions

Q: Can the RX 7700 XT run ray tracing at all in modern games?

A: Yes, the RX 7700 XT supports DirectX Raytracing and can run ray tracing in virtually all modern games that support it. The question is at what frame rate and at which resolution those settings remain enjoyable. At 1080p with moderate RT settings and FSR 3 upscaling active, the 7700 XT delivers playable results in most titles.

Q: Does the RX 9070 XT support AMD's FSR 4 fully?

A: Yes. FSR 4's machine learning-based upscaling mode requires RDNA 4 architecture, and the RX 9070 XT is an RDNA 4 card. This gives 9070 XT owners access to the highest quality upscaling tier AMD has released, which is particularly valuable when ray tracing is enabled and native frame rates drop.

Q: Is ray tracing worth enabling at 1080p on either card for SA gamers on 1080p monitors?

A: At 1080p, the performance headroom is greater because the native rendering workload is lower, making ray tracing more viable on both cards. The 9070 XT handles 1080p RT comfortably. The 7700 XT manages it in lighter implementations. If you have a 144Hz 1080p monitor and want both ray tracing and high frame rates, the 9070 XT is the more capable card.

Q: Should SA gamers on a tight budget choose the RX 7700 XT over the RX 9070 XT?

A: If your budget is constrained and you primarily play esports titles or older games without ray tracing, the RX 7700 XT offers strong rasterisation performance at a lower cost. The 9070 XT is worth the premium for SA gamers who prioritise ray tracing in current-generation AAA single-player titles and want their GPU to handle RT-heavy titles released over the next two to three years.
