AMD Radeon RX 6600 XT Unleashed – A GeForce RTX 3060-killer?

AMD recently announced its latest GPU, the Radeon RX 6600 XT graphics card. Aimed towards 1080p gamers, the RX 6600 XT is targeting users who are still using a GTX 1060 (or older) GPU, offering up to a “2.5x performance” increase. It’s also AMD’s answer to NVIDIA’s GeForce RTX 3060 graphics card. It would be interesting to see which GPU will perform better. Offering 32 compute units and 8GB GDDR6 memory, the RX 6600 XT starts at $379 USD. Check out more details below.


AMD Radeon RX 6600 XT Graphics Card Offers “Epic” 1080p Gaming Performance

Right of the bat, the Radeon RX 6600 XT is AMD’s solution for 1080p gaming. It features 32 compute units, 8GB of GDDR6 memory, 32MB of infinity cache, and a game clock speed of 2359MHz. It has a TDP of 160w and requires a single 8-pin PCIe power connector, for the reference model.

The RX 6600 XT also comes with 2048 Stream Processors, 32 Ray accelerators, 64 ROPs and 128 texture units. It’s capable of 10.6 TFLOPS of peak single precision compute performance or 21.21 TFLOPS of peak half precision compute performance. Below are more features that the RX 6600 XT offers.

Other Features

  • AMD FidelityFX – Now supported by 50 titles and game engines, AMD FidelityFX is an open-source toolkit of visual enhancement effects for game developers available at AMD GPUOpen. Offering broad support on more than 100 AMD processors and GPUs, as well as on competitor GPUs, the new AMD FidelityFX Super Resolution upscaling technology delivers 2.4X higher performance on average in “Performance” mode at 4K across select titles compared to native resolution5.
  • AMD Smart Access Memory – Unlocks higher performance when pairing AMD Radeon RX 6000 Series graphics with AMD Ryzen™ 5000 or select Ryzen 3000 Series Desktop Processors and AMD 500-series motherboards. Providing AMD Ryzen processors with access to the entire AMD Radeon RX 6600 XT high-speed 8 GB GDDR6 graphics memory can deliver a performance uplift of up to 11 percent on average in select titles6.
  • AMD Infinity Cache – 32 MB of last-level data cache integrated on the GPU die reduces latency and power consumption to enable higher gaming performance than traditional architectural designs.
  • DirectX® 12 Ultimate Support – Enables games to deliver mind-blowing visuals with real-time DirectX Raytracing (DXR), Variable Rate Shading, and other advanced features, elevating games to a new level of realism.
  • AMD Radeon Anti-Lag – Helps decrease input-to-display response times, making games more responsive and offering a competitive edge in gameplay.
  • AMD Radeon Boost – AMD Radeon Boost with support for Variable Rate Shading can provide up to a 48-percent performance increase in Warframe7 during fast-motion gaming scenarios by dynamically reducing image resolution or by varying shading rates for different regions of a frame, increasing framerates and fluidity, and bolstering responsiveness with virtually no perceptual impact on image quality.

Radeon RX 6600 XT – Faster Than RX 5600 XT and RX 5700

AMD showed several performance graphs during the presentation. One of the slide shows that the RX 6600 XT, with Smart Access Memory (SAM) enabled, is faster than the previous generation RX 5600 XT and RX 5700.


This result came from AMD’s internal testing and it’s a very general graph with no specific games or frame rates. I expect that the RX 6600 XT would be faster than the RX 5600 XT. But it could be on par with the RX 5700 XT when it comes to performance, or perhaps a hairline faster.

RX 6600 XT vs RTX 3060 and GTX 1060

AMD also showed a slide revealing that the RX 6600 XT is up to 2.5x faster than the GTX 1060 in 1080p resolution. Again, this is with SAM enabled.


Finally, AMD compared the 6600 XT to NVIDIA’s latest RTX 3060. This time, the graphs show that it is just slightly faster than the RTX 3060. Some of the games in the slides are AMD-sponsored or favors AMD GPUs in general. Nevertheless, it would be interesting to see which graphics card is better – RTX 3060 or RX 6600 XT.

Radeon RX 6600 XT From AIB Partners

During the announcement, AMD also revealed some of the RX 6600 XT graphics cards from AIB partners, featuring a custom-designed cooler. Some of these are the ASrock RX 6600 XT Phantom Gaming D, Asus ROG Strix RX 6600 XT Gaming, Gigabyte RTX 6600 XT Gaming OC Pro, MSI RX 6600 XT Gaming X, Powercolor RX 6600 XT Red Devil, Sapphire RX 6600 XT Nitro+, and XFX Radeon RX 6600 XT MERC.

Of course, these are not the only 6600 XT that will be launching this month or in the following months. And there are usually different variants of an RX 6600 XT graphics card offered by one brand or partner.

Stay tuned as we will be checking out some of these RX 6600 XT very soon. I’m also curious to find out which will be the new “1080p-king GPU”.
