If you are looking for a power-efficient mid-range card for ultimate 1080p gaming then Radeon RX 6600 XT is one of the better options available in the market. It is the youngest member in the AMD Radeon RX 6000 series and sits directly below the RX 6700 XT, which is a very good 1440p gaming card. Even though RX 6600 XT is targeted towards 1080p gaming, it is still very capable for 1440p gaming too if you can compromise on some advanced in-game graphics settings. The major competitors of RX 6600 XT are RTX 3060, RTX 3060 Ti, and even the RX 5700 XT which is an AMD card itself from the previous generation. Talking about performance, RX 6600 XT is faster than RX 6600 XT by 12% on average and is slower than RTX 3060 Ti by up to 25%. Also, it is faster than the RX 5700 XT but by a small margin only. The major advantage of RX 6600 XT over its is competitors is that it is very efficient in the power consumption department and draws very little power for the performance it offers.

Radeon RX 6600 XT is built on the RDNA 2 GPU architecture on a smaller 7nm fabrication process. It uses Navi 23 XT and comes with 2048 Stream Processors and 32 Ray Accelerators. The card is equipped with 8GB GDDR6 memory that is 128-bit wide and runs at 16 Gbps offering an effective memory bandwidth of 256 GB/s. However, it can achieve a much higher peak memory bandwidth by using the 32MB Infinity Cache present on the GPU. The card supports PCI Express 4.0 but is limited to x8 link speed only which can become an issue on PCIe 3.0 motherboards with the latest memory-intensive AAA games. Other features that are supported include DirectX 12 Ultimate, OpenGL 4.6, and Vulkan, Real-Time Ray Tracing, HDMI 2.1, AV1 decode, Resizable BAR, AMD FidelityFX Super Resolution (FSR), Microsoft DirectStorage API (to reduce game loading times), variable refresh rate technology FreeSync to reduce game stuttering. There is no reference RX 6600 XT model available from AMD and only custom models are available from various AIB manufacturers. So, to help you pick the right RX 6600 XT model, here I am listing the best RX 6600 XT cards based on different parameters that include overclocking, form factor, thermal performance, noise, etc.

Best Overclocked & Coolest RX 6600 XT

ASUS ROG Strix Radeon RX 6600 XT OC Edition

[Dual BIOS, Very Low Temperatures, Good Overclocking Potential, Stylish Design & RGB Lighting]

ASUS ROG Strix Radeon RX 6600 XT OC Edition is the cooling running and the best overclocked RX 6600 XT card you can find. The card comes with a Game Frequency of 2448 MHz and a Boost frequency up to 2607 MHz. For cooling, the card uses a large fin array aluminum heatsink with four copper heatpipes and dual Axial-tech fans. The two Axial-tech fans use dual ball bearings for durability and feature half-width barrier rings to increase the airflow into the heatsink. The 0dB mode delivers semi-passive cooling as fans start only when the GPU temperature hits 60 degrees Celsius and shut off when GPU temperature drops below 52 Celsius during idle or light loads. The card also comes with Dual BIOS and you can switch between the Performance (P) and Silent (S) BIOS modes (via Dual BIOS switch) according to your requirements. In the default Performance mode, the card is pretty noisy but in Silent mode, it stays relatively quieter.

It is a 2.6 Slot card but is relatively compact having a length of 243mm. A vented metal backplate protects the card from damage and also helps in the cooling. Moreover, a Stainless Steel I/O Bracket and metal GPU Bracket further adds to the rigidity of the card. The shroud of the card has a metallic finish with silver elements that look very stylish and gives the card a premium look. The card supports Asus Aura Sync RGB LED Lighting and the RGB Lighting can be seen on the front and top side of the shroud. The card requires one 8-pin PCIe connector and 500W PSU for power. Using the ASUS GPU Tweak II GPU tuning and overclocking software, you can tweak critical parameters including GPU core clocks, memory frequency, and voltage settings, with the option to monitor everything in real-time through a customizable on-screen display (OSD). Display connectivity options include three DisplayPort 1.4a ports and one HDMI 2.1 port.

Important Note: “Game Clock” is the expected GPU clock when running in typical gaming applications, set to typical TGP (Total Graphics Power).
