New leak suggests that AMD is about to release two new graphics cards

AMD may be about to launch two new Navi 23 graphics cards, according to a new leak. Drivers for the RX 6600 and RX 6600XT have been found in a recent update, suggesting that AMD is likely preparing to release these two GPUs soon. The information comes from a leaker known on Twitter as @KOMACHI_ENSAKA, who posted screenshots of AMD’s recent drivers, including both of the new RX 6000-series cards.

It’s possible that these are the graphics cards AMD was talking about earlier this year at CES 2021, an annual trade show organized by the Consumer Technology Association. During that event, AMD announced that it would be releasing a single-fan GPU in the future. It now seems that the cards in question may in fact have been the Radeon RX 6600 and 6600XT.

We don’t know the full specifications of the upcoming cards just yet, although some information has already been revealed. Part of that knowledge stems from the fact that both of these cards are housing a Navi 23 GPU. Navi 23 comes with a 128-bit memory bus and 2,048 stream processors. The GPU measures 237mm2 and has 11.06 billion transistors. It also utilizes 10 teraflops (TFLOPs) and runs on up to 100 watts of power.

Previous rumors suggest that the AMD Radeon RX 6600XT graphics card will provide 8GB of GDDR6 memory. Assuming this turns out to be true, the 6600 might come with 4GB VRAM. However, there’s a chance that even the RX 6600 will be decked out with the full 8GB. Both models are likely to come with a 32MB AMD Infinity Cache.

It’s possible that the RX 6600 will come with 28 compute units, while the RX 6600XT will have 32. Both the cards will have a 7nm process node. Most of the other specs are pure guesswork at this point. Rumors suggest a 128-bit memory bus for the RX 6600 and a 192-bit for the RX 6600XT, as well as a 16Gbps memory clock with 256GB/s of bandwidth for both models.

These graphics cards are likely to be the first Navi 23 GPUs for AMD when it comes to the gaming sector. The company already has Navi 23 cards out on the market, but they are found inside mobile devices and high-end workstations. They can also be found inside Tesla’s Model S vehicles. According to Elon Musk, the CEO of Tesla, the performance of that system will be powerful enough to rival that of Sony’s Playstation 5 consoles.

Like any leak, this should be taken with skepticism, but it does come from a reputable source with a proven track record. Another leak has also recently confirmed that Gigabyte is about to release six custom GPUs from the RX 6600 XT series, further signaling that the cards are almost ready. Given that, as well as the hints from AMD, we are looking at a possible release shortly. All the information put together suggests a simultaneous launch within the next few months.

Trying to buy a GPU in 2023 almost makes me miss the shortage
Two AMD Radeon RX 7000 graphics cards on a pink surface.

The days of the GPU shortage are long over, but somehow, buying a GPU is harder than ever -- and that sentiment has very little to do with stock levels. It's just that there are no obvious candidates when shopping anymore.

In a generation where no single GPU stands out as the single best graphics card, it's hard to jump on board with the latest from AMD and Nvidia. I don't want to see another GPU shortage, but the state of the graphics card market is far from where it should be.
This generation is all over the place

Just a day after AMD announced its plans to launch new Radeon 7000 desktop GPUs at its quarterly earnings call, we’ve got credible information on one of the upcoming models. AMD GPU board partner PowerColor briefly posted a listing for its upcoming Radeon RX 7800 XT with complete specifications before pulling down the page.

The listing was spotted by Twitter user @All_The_Watts who had previously shared alleged performance numbers for the RX 7700 and RX7800. According to the page, the PowerColor RX 7800 XT ‘Red Devil’ graphics card will feature 3840 stream processors, 60 compute units, and a 256-bit memory interface with 576GB/s bandwidth. It will feature 16GB of GDDR6 memory and offer boost clock speeds that can go up to 2,565 MHz in OC mode.
