Is Ray Tracing Better on GTX or RTX? The Definitive Answer
The short and sweet answer: Ray tracing is significantly better on RTX cards. While some GTX cards can technically support ray tracing, the performance is severely limited compared to RTX cards. RTX GPUs are specifically designed with dedicated hardware, like RT Cores, to handle the complex calculations required for real-time ray tracing. This results in a much smoother, more visually impressive experience, especially at higher resolutions and settings. The difference in visual fidelity and frame rates is often night and day.
The Technical Breakdown
To understand why RTX reigns supreme, let’s delve into the technology behind ray tracing and the architecture of these graphics cards.
Understanding Ray Tracing
Ray tracing is a rendering technique that simulates the physical behavior of light. Instead of relying on traditional rasterization methods, which approximate lighting and shadows, ray tracing traces the path of individual light rays as they bounce around a scene, interacting with objects and surfaces. This results in more realistic reflections, shadows, and global illumination. The effect is a significantly more immersive and visually rich gaming experience.
However, accurately simulating these light interactions requires immense computational power. This is where the dedicated hardware of RTX cards comes into play.
RTX Architecture: RT Cores and Tensor Cores
Nvidia RTX cards feature two key hardware components that accelerate ray tracing:
- RT Cores: These are specialized units designed solely for handling ray tracing calculations. They offload the burden from the main GPU cores, allowing for much faster and more efficient ray tracing performance.
- Tensor Cores: These cores are designed for AI-related tasks, including Deep Learning Super Sampling (DLSS). DLSS uses AI to upscale lower-resolution images to higher resolutions, improving performance without sacrificing visual quality. This is especially crucial when ray tracing is enabled, as it helps to offset the performance impact.
GTX cards, on the other hand, lack these dedicated hardware units. While they can perform some ray tracing calculations using their general-purpose GPU cores, the performance is significantly lower.
GTX Limitations: A Struggle for Performance
While Nvidia did enable ray tracing on some high-end GTX cards (like the GTX 1660 SUPER and GTX 1660 Ti) via a driver update, the experience is far from ideal. These cards struggle to maintain playable frame rates, even at lower resolutions and settings, with basic ray tracing effects enabled.
The lack of RT Cores means that GTX cards must rely on their standard CUDA cores to handle ray tracing, which significantly impacts overall performance. The difference is often a slideshow versus a smooth, playable game. For example, with a GTX card you might only get basic ray tracing effects with a low ray count, while an RTX graphics processor can manage much more complex effects with multiple effects being presented with a higher ray count.
DLSS: The RTX Advantage
DLSS is a game-changer for ray tracing performance. By using AI to upscale lower-resolution images, DLSS can dramatically improve frame rates without sacrificing visual fidelity. This is particularly important when ray tracing is enabled, as it helps to offset the performance hit.
DLSS is primarily supported on RTX cards, giving them a significant advantage in terms of overall performance and visual quality when ray tracing is enabled. While some games support similar upscaling technologies on GTX cards, they are often not as effective as DLSS.
The Verdict
In conclusion, while GTX cards can technically support ray tracing, the performance is severely limited. RTX cards, with their dedicated RT Cores and Tensor Cores, offer a much superior ray tracing experience. If you’re serious about enjoying ray tracing in your games, an RTX card is the clear choice.
Ray Tracing: Is it Worth the Hype?
Ray tracing undoubtedly enhances the visual experience in games, offering more realistic lighting, shadows, and reflections. The degree to which it impacts the immersive experience depends on individual preferences and the quality of the implementation within each game. However, the increased demand on GPU resources requires balancing visual enhancements with performance considerations.

Frequently Asked Questions (FAQs) about Ray Tracing
1. Can I enable ray tracing on any GTX card?
No. Only select high-end GTX cards, such as the GTX 1660 SUPER, GTX 1660 Ti, and some variants of the GTX 10 series, officially support ray tracing via driver updates. However, performance will be limited compared to RTX cards.
2. What’s the minimum RTX card recommended for ray tracing?
The RTX 2060 is often considered the minimum for a decent ray tracing experience at 1080p, but an RTX 3060 or higher is recommended for better performance and higher resolutions. For 1440p or higher resolutions, an RTX 3070 or above is highly recommended.
3. Does ray tracing significantly impact FPS?
Yes. Ray tracing is computationally intensive and can significantly reduce frame rates. However, technologies like DLSS can help mitigate this performance impact.
4. Is DLSS only available on RTX cards?
Yes, DLSS (Deep Learning Super Sampling) is an Nvidia RTX technology, utilizing the Tensor Cores available exclusively on RTX cards. There are alternative upscaling technologies available on GTX and AMD cards, but DLSS is widely regarded as the most effective.
5. Does ray tracing require a powerful CPU?
While the GPU is the primary bottleneck for ray tracing, a decent CPU is still important to avoid CPU bottlenecks. A modern quad-core or higher processor is generally recommended. A 13th-gen Intel Core i5; AMD Ryzen 5 7000 series would be good for ray tracing.
6. Is ray tracing only for gaming?
No. Ray tracing is also used in other applications, such as 3D rendering, animation, and architectural visualization.
7. Do all games support ray tracing?
No. Ray tracing needs to be specifically implemented by the game developers. While the number of games supporting ray tracing is growing, it’s still not a standard feature in all games.
8. Will older games be updated with ray tracing?
Some older games may receive ray tracing updates, but this is not guaranteed. It depends on the developer’s willingness and resources to implement the technology.
9. Is ray tracing a gimmick or a genuine improvement?
While subjective, most gamers agree that ray tracing significantly enhances visual fidelity and immersion. However, whether it’s worth the performance cost is a personal decision.
10. What’s the difference between ray tracing and path tracing?
Path tracing is a more advanced form of ray tracing that simulates the entire path of light, including multiple bounces. While more realistic, it’s also more computationally intensive. Nvidia’s RTX cards use hybrid ray tracing techniques, which combine traditional rasterization with ray tracing to optimize performance.
11. Is ray tracing only for NVIDIA cards?
No. AMD also offers ray tracing support with their Radeon RX 6000 and 7000 series GPUs. However, the performance and features may differ from Nvidia’s RTX cards.
12. Does ray tracing increase the price of graphics cards?
Yes. RTX cards, which offer dedicated hardware for ray tracing, are generally more expensive than GTX cards.
13. Can ray tracing damage my GPU?
No. Ray tracing itself won’t damage your GPU, but it can increase its temperature. Make sure your GPU has adequate cooling to prevent overheating.
14. What is the cheapest GPU that can Ray Trace?
While the RTX 3060 Ti is the cheapest we’ve benchmarked to offer reliable post-60fps performance with ray tracing on in 1080p. RTX 3050 also performs much better than the GTX 1650 as it has faster core clocks and more VRAM.
15. Is RTX 3060 overkill for 1080p?
The RTX 3060 Ti is not an overkill, that card has a good value and actually is more meant for 1080p maybe 1440p.
In conclusion, for those prioritizing enhanced graphics and realistic lighting effects, upgrading to an RTX card is a worthwhile investment. The technology is constantly evolving, promising even more impressive visual experiences in the future.
