AMD Reveals Radeon RX 6600 XT Specs, Pricing, and Performance

Prepping for another sold out launch on August 11

AMD's Radeon RX 6600 XT will officially launch on August 11, 2021, putting to rest the past couple of months of speculation and leaks. Will it manage to compete with the best graphics cards, and where will it fall in terms of our GPU benchmarks hierarchy—and more importantly, will more than a handful of people be able to buy the cards at something close to MSRP? These are good questions, and while the answer to that last question is almost certainly, "Sorry, not gonna happen," it should still bring some needed competition to the more moderately priced GPU segment.

First, let's talk official pricing. AMD says the RX 6600 XT will launch with a suggested retail price of $379. That's not quite the price many were hoping to see, but AMD says it has adjusted prices based on what people might see at retail. In other words, it's not pulling out a 'fake' $329 MSRP like Nvidia's RTX 3060, which generally sells for $500 or more right now—assuming you can even find one in stock. Check our GPU price index for more details. Of course, $379 is only the starting price, and we'll undoubtedly see much higher prices on many of the custom cards from AMD's AIB (add-in board) partners.

The Radeon RX 6600 XT specs have been widely leaked and guessed at, and it looks like many of those were accurate. It will use a new Navi 23 GPU, which supports up to 32 CUs—and the RX 6600 XT will feature the fully enabled chip. That means 2048 streaming processors (aka, GPU cores), 32 ray accelerators, and 9.7 TFLOPS of FP32 compute. It will also feature a 128-bit memory interface with 8GB of GDDR6 16Gbps memory, good for 256GBps of bandwidth, augmented by 32MB of Infinity Cache. There are a few remaining questions, like the die size, transistor count, and number of ROPs (probably 48 ROPs); the TDP comes in at just 160W.

Figuring out just where the RX 6600 XT will land in terms of performance is a bit tricky. The raw specs aren't particularly impressive on the one hand, but we do know the RDNA2 architecture tends to deliver significantly better performance than AMD's previous GPUs—thanks in part to the Infinity Cache, but also helped a lot by the high clock speeds. 32MB won't be as beneficial as the 96MB and 128MB Infinity Cache sizes we've seen on other RX 6000-series GPUs, but AMD says the RX 6600 XT targets 1080p gaming, and that the cache size was chosen to best fit that market, while keeping costs in check.
