The latest step in the graphics card pas de deux between AMD and Nvidia is theGPU. It’s also the current entry-level model in AMD’s line of graphics processors for gamers specifically looking for speed or higher quality in 1080p resolution. The RX 6600 XT’s nominal $379 price and performance slots seamlessly between Nvidia’s $329 and $399 — all in the seemingly choreographed fashion we’re used to from the two manufacturers.
Both AMD and Nvidia are desperately attempting to get gamers to upgrade from the four-year-old GeForce GTX 1060, which still has the biggest installed base. But this is the absolute worst time to buy a graphics card… and has been for a while. Yes, theand may lessen the demand for GPUs, but we’re still in the middle of a that affects many components of graphics cards and . So it’s bound to keep availability low, shopbots busy and prices high. And if you’re looking at these low-ish end cards, you’re probably really price-sensitive to begin with, making it a doubly bad time — unless you’re desperate.
Like Nvidia’s 3060 models, there’s no official AMD-branded version of a card using the RX 6600 XT GPU, so we tested the Asus ROG Strix RX 6600 XT OC, a $550 dual-fan overclockable model that acquits itself well for what it is. (There’s also a smaller, lower-key version of the card in the Asus Dual product line line for $500.) But in our testing, the 6600 XT at best matched or marginally outpaced the RTX 3060, even conservatively overclocked, which at least partly stems from the AMD GPU’s 8-lane PCIe connection rather than NVIDIA’s 16-lane connection. However, without knowing what the actual-real-true prices are as opposed to the what-planet-do-you-live-on prices, it’s difficult to make a call about which GPU to recommend you make a fruitless attempt to buy.
The lesser slot requirement may make it a little more flexible for fitting into older systems, but it really cuts potential performance; if it took advantage of the higher-bandwidth slot it might give the 3060 Ti some competition.

Asus has done a fine job eking out what it can from the GPU and it certainly delivers on the 1080p high-frame-rate promise. Physically, the card’s a bit chunky for what it delivers at 2.6 slots wide, but the space allocated to the passive cooling (four heatpipes forcing the heat toward a large heat spreader and heatsink) allows it to reduce reliance on the fans at high speeds. This makes it pretty quiet and I kept having to check the monitoring utility to convince myself the fans were even spinning.
In addition to monitoring, the GPU Tweak 2 utility Asus provides lets you choose from a silent mode (with a 0dB fan toggle), gaming mode (which weights performance, cooling and noise equally) and an OC mode to maximize performance via an overclock preset or manual controls over the GPU and memory clocks, voltage, fan speed and a power target. Like the other cards in the line, there’s also a toggle switch to jump between two BIOSes, one optimized for performance and the other for noise.
You can use the company’s Armoury Crate software to control the logo lighting scheme, but I’m not a big fan of the software; it’s just too cumbersome for my taste.
The card supports all the latest AMD features. They include Radeon Boost (which selectively renders scene elements at a lower resolution, based on visibility, for higher frame rates), Radeon Anti-Lag (reduces latency by lightening the load on the CPU), FidelityFX Super Resolution (upscaling from lower-resolution textures to achieve faster frame rates, a la Nvidia DLSS) and Smart Access Memory (AMD’s Resizable BAR implementation, in which the CPU can store game-related data in GPU RAM rather than system RAM so the GPU doesn’t have to traverse the system bus to retrieve it).
AMD is less reliant on developer support than Nvidia for much of its acceleration, but it’s not entirely driver-based. Smart Access Memory only works on systems equipped with a modern AMD Ryzen CPU, for example.
Unless you’re looking for the cheapest RX 6000-series AMD options, I don’t think the RX 6600 XT is the best choice for its price class; the RTX 3060 Ti seems like it delivers far better performance for (theoretically) not much more. And I wouldn’t rule out an even lower-end model appearing later this year to satisfy your budget-constrained 1080p play — there was an RX 5500, so it’s always possible we’ll see even lower end RX 6500 or RX 6500 XT models at some point for basic 1080p gaming.
