The Radeon RX 6600 XT features a Navi 23 graphics chip that was built on TSMC’s 7 nm manufacturing process. The chip features 11.06 million transistors, and features 2,408 shading units, 32 compute units, and 32 raytracing cores. Compared to the Radeon RX 6700 XT, this GPU features 50% less shading units, and 77% less CUs. This may sound a bit disappointing, however, keep in mind that the RX 6700 XT was designed for 4K gaming in mind, while the RX 6600 XT is primarily intended for users who want to game at 1080p or 1440p resolutions. Compared to the previous-generation RX 5600 XT, the RX 6600 XT is 27% faster, and is only 3% slower than the GeForce RTX 2080. The card features 8GB of GDDR6 VRAM, clocked at 16 Gbps, and fully supports PCIe 4.0 interface.

The reference Radeon RX 6600 XT comes with a base GPU clock speed of 1,968 MHz, and a boost clock of 2,359 MHz. Just like all the other RX 6000 series graphics cards, this one also sports unusually high core clocks. However, the Radeon RX 6600 XT is a relatively energy-efficient graphics card, since it features a TDP of 160 watts, and requires only one 8-pin connector to run.

Speaking of its performance, the Radeon RX 6600 XT is a very interesting graphics card. In titles like Borderlands 3, Death Stranding, Dirt Rally 2.0, and Assassin’s Creed Odyssey, it outperforms the GeForce RTX 3060 at 1080p by over 20%. However, this card struggles with ray-tracing, since the NVIDIA’s RTX 3060 outperforms the RX 6600 XT in most games featuring ray-tracing, such as Control, Metro Exodus, and Battlefield 5 (by up to 40%). With DLSS, the GeForce RTX 3060 delivers even higher frame-rates, meaning that the RX 6600 XT is no match for it, at least until AMD’s FSR technology starts seeing its first implementations.

When it comes to mining, the Radeon RX 6600 XT falls short of expectations, as this 2021 graphics card is able to deliver the same hashrate as the four-year-old Radeon RX 580 on Ethash algoritm (around 32 MH/s). However, the power consumption of this card is simply fantastic, since the RX 6600 XT consumes only around 80 W while mining Ethereum, and that is without any undervolting, underclocking, or custom BIOS mods.

This card is only available in AIB variations. However, because each variant has different cooling and GPU clock speeds, we’ve created a list of the top aftermarket models to assist you in choosing the perfect card. To view more, scroll below.

If, however, you are in pursuit of all the extra fancy features, such as dual BIOS switch, RGB LED, and exchangeable fans, then consider checking out the Sapphire NITRO+ RX 6600 XT.

Despite its simple appearance, this card features 23 MHz higher GPU boost clock than the reference model, and comes with hybrid fan blades that combine the best from axial and blower-style fans. Performance-wise, the Sapphire PULSE RX 6600 XT can deliver almost 100 FPS in games like Horizon Zero Dawn and Borderlands 3 at 1080p resolution, which is quite impressive. The card also runs very quietly, so if you are looking for a nice and simple GPU for 1080p gaming on ultra settings, then this is the card for you.

Best for Overclocking: ASUS ROG Strix Radeon RX 6600 XT OC

Boost Clock: 2607 MHz | Memory: 8GB GDDR6 | Power Connectors: 1 x 8-pin | Outputs: 3 x DP, 1 x HDMI


  • Great 1080p and 1440p performance
  • Fantastic overclocking potential
  • Great thermal performance
  • Dual BIOS switch

Unlike many other card, this one has two HDMI and two DisplayPort connectors. Despite its small size, this card features a proper Navi 23 graphics chip, meaning you can except very good performance from it. Speaking of its thermals and acoustics, this is a surprisingly good SFF card, since its huge single axial fan can keep the GPU below 82°C at 50% RPM, while being almost inaudible. Overall, the fact that this card is inexpensive, comes with a backplate, and operates silently is most praiseworthy. Its only flaw, albeit a minor one, is that it may require a bit of tinkering until you find out the best balance between the fan RPM, noise, and GPU core temperature.

Best Design: ASRock Radeon RX 6600 XT Phantom Gaming D 8GB OC

Boost Clock: 2607 MHz | Memory: 8GB GDDR6 | Power Connectors: 1 x 8-pin | Outputs: 3 x DP, 1 x HDMI

  • Very good overclocking potential
  • High-quality PCB components
  • ARGB LED lighting
  • Stylish metallic backplate
  • Very expensive

In terms of performance, design, acoustics, and thermals, the ASRock Radeon RX 6600 XT Phantom Gaming D is simply an outstanding product. Featuring a boost clock of 2,607 MHz, this card is around 3% faster than the base RX 6600 XT right out of the box. However, if overclocked, the RX 6600 XT Phantom Gaming D can easily hit 2,700 MHz GPU boost clock speed, meaning it can deliver up to 5% better performance.

Speaking of its design, this card looks fantastic. It features a stylish metal backplate, three striped axial fans, and nice-looking heatsink shroud with built-in ARGB LEDs. Its heatsink also features air deflecting fins to deliver improved airflow, resulting in whisper-quiet operation and lower operating temperatures. Under full load, the RX 6600 XT operates at temps between 55 and 60°C, and produces around 31 dB of noise, which is more than ideal. Its only flaw is that it’s quite expensive, and that it hardly justifies its very high price tag despite providing extraordinary performance.
