Radeon RX 6500 XT vs GeForce GTX 1660 SUPER: Full Comparison
Introduction
Choosing a graphics card in the entry-level to mid-range segment often involves comparing newer, more efficient architectures against older, sometimes more fully-featured designs. The comparison between the AMD Radeon RX 6500 XT and the NVIDIA GeForce GTX 1660 SUPER highlights this dynamic. This analysis will examine their specifications, gaming performance, feature sets, and overall value proposition to help clarify their respective positions in the market.
Architecture and Specifications
The core differences between these two GPUs begin with their underlying technology. The RX 6500 XT is based on AMD’s newer RDNA 2 architecture, which is also found in more powerful contemporary cards. The GTX 1660 SUPER utilizes NVIDIA’s older, but well-established, Turing architecture.
- Process Node: The RX 6500 XT is manufactured on a 6nm process, while the GTX 1660 SUPER uses a 12nm process. The newer process can contribute to better power efficiency.
- VRAM: A key differentiator is video memory. The GTX 1660 SUPER features 6GB of GDDR6 memory on a 192-bit bus. The RX 6500 XT has 4GB of GDDR6 on a narrower 64-bit bus.
- PCIe Interface: The RX 6500 XT supports PCIe 4.0, but often uses only a x4 connection. The GTX 1660 SUPER uses the older PCIe 3.0 standard with a full x16 connection.
Gaming Performance
Performance can vary significantly depending on the game, resolution, and graphical settings used.
- 1080p Gaming: In many traditional rasterized games, the GTX 1660 SUPER often maintains a slight to moderate performance lead, especially at higher quality settings where its larger VRAM buffer is an advantage.
- Memory Limitations: The 4GB VRAM on the RX 6500 XT can become a limiting factor in newer games with high-resolution textures, potentially leading to stuttering or the need to lower texture quality.
- Feature Support: The RX 6500 XT supports newer graphical features like hardware-accelerated ray tracing and AMD’s FidelityFX Super Resolution (FSR). However, its performance with ray tracing enabled is typically limited due to its entry-level positioning. The GTX 1660 SUPER lacks dedicated ray tracing cores.
Features and Technologies
Each card brings a different set of technologies to the table, influenced by their respective generations.
- Upscaling: The RX 6500 XT supports AMD FSR (1.0, 2.0, etc.), which can boost frame rates. The GTX 1660 SUPER supports NVIDIA’s DLSS, but only the first version, which is supported in a more limited number of games.
- Video Encoding: A notable omission on the RX 6500 XT is the lack of a dedicated hardware video encoder (like H.264/H.265), which can impact streaming or video recording performance. The GTX 1660 SUPER includes NVIDIA’s NVENC encoder.
- Display Outputs: Both cards typically support multiple modern displays, but the specific outputs (like HDMI 2.1 on the RX 6500 XT vs. HDMI 2.0b on the GTX 1660 SUPER) can differ.
Power and Efficiency
The power draw and thermal design of a GPU can influence case and power supply requirements.
- TDP: The Radeon RX 6500 XT generally has a lower Typical Board Power (TDP), often around 107 watts. The GeForce GTX 1660 SUPER typically has a TDP of approximately 125 watts.
- Power Connectors: Both cards usually require a single 6-pin or 8-pin PCIe power connector, making them compatible with many standard power supplies.
- Cooling: Cooling solutions vary by manufacturer, but both GPUs are known for relatively modest thermal output, often allowing for compact and quiet cooler designs.

Frequently Asked Questions (FAQ)
What is the main performance difference between the RX 6500 XT and GTX 1660 SUPER?
The GTX 1660 SUPER generally offers more consistent performance in a wider library of games, particularly at 1080p with higher texture settings, largely due to its 6GB of VRAM. The RX 6500 XT can perform well in less VRAM-demanding titles and benefits from newer features like FSR.
Which card is better for streaming or video recording?
The GeForce GTX 1660 SUPER is typically the more suitable choice for streaming or recording gameplay because it includes NVIDIA’s dedicated NVENC hardware encoder. The Radeon RX 6500 XT lacks a dedicated encoder, which places the encoding workload entirely on the system’s CPU.
Does the RX 6500 XT’s PCIe 4.0 support provide a big advantage?
The advantage is often limited. While PCIe 4.0 offers higher bandwidth, the RX 6500 XT only uses a x4 lane configuration. This can lead to a performance penalty if the card is used in an older PCIe 3.0 system, as the available bandwidth is significantly reduced compared to its operation in a PCIe 4.0 system.
Can either of these cards handle ray tracing?
The Radeon RX 6500 XT has hardware support for ray tracing, but its performance when enabling the feature is usually quite low due to its entry-level design. The GeForce GTX 1660 SUPER does not have dedicated ray tracing cores, so any ray tracing effects would be handled by the traditional shader cores, resulting in a very substantial performance impact.
Final Thoughts
This comparison illustrates a common choice in the budget GPU segment: opting for a newer architecture with modern features or an older design with potentially more practical resources for today’s games. The Radeon RX 6500 XT brings contemporary elements like PCIe 4.0 support and FSR upscaling, but its 4GB VRAM can be a constraint. The GeForce GTX 1660 SUPER, while based on older technology, often delivers more reliable performance across a broader spectrum of games thanks to its larger memory configuration and includes a hardware video encoder. The more appropriate choice generally depends on the specific games being played, the system it’s paired with, and whether features like streaming are a priority.
