We may be looking at the final specifications of the AMD Radeon RX 6600 XT and RX 6600 here. Based on the Navi 23 GPU, the new GPU-Z screenshots are intended to showcase the RX 6600 XT with 2,048 cores, and the reduced RX 6600 offers just under 1,792. It is important to note that both include 8 GB of GDDR6 memory.
The information comes from two GPU-Z screenshots, which appeared in the Chiphell technology forum (via Videocardz). They claim to list the specifications of the two unreleased RDNA 2 graphics cards, the first of which is the AMD Radeon RX 6600 XT, called 73FF C1, and built on the Navi GPU 23. Its 2,048 cores would accompany 32 ROP and 128 TMU and would be accessible via a 128-bit bus and 8 GB of GDDR6.
Then there is the RX 6600 with only 1,792 cores, 32 ROPs and 112 TMUs. This card also includes 8GB of GDDR6 and a 128-bit bus.
Both would feature the same RDNA 2 architecture, which is currently on the RX 6700 XT to the RX 6900 XT.
These two GPUs also recently appeared on an ASRock CEE listing and where there is smoke, there is fire. We haven’t had any official confirmation from AMD regarding the launch of any budget or mid-range graphics cards, but it wouldn’t go from AMD to moving to a virtual E3 with its own stream and announcing both cards.
The potential key to the works is the ongoing GPU shortage, but as Nvidia begins to deploy cheaper GPUs to RTX 3060 12GB and RTX 3050 Ti and RTX 3050 mobile, perhaps the pressures are rising for AMD's own RDNA 2 response.
Beyond the Navi 23 GPU, codenamed Dimgrey Cavefish, by the way, there are now confirmation in Linux driver code of another GPU code name: Beige Goby (via Phoronix). It will probably be Navi 24, this chip would probably be pretty thin for our gaming tastes as it is today, but that could be good news for budget gamers looking for their first real-level fix from Polaris.
There’s definitely more to come out of the RDNA 2 architecture, and if AMD’s trajectory is something that needs to happen, it could be where the company performs best. That is, if the global shortage of chips does not interfere. Something tells me that we will still be fighting for action for a long time.
If AMD’s RDNA 2 GPUs start to outperform the Ethereum hash rates of the RTX 30 series, they could end up in high demand. It is beginning to seem that this may also be the case. The RX 6600 XT reports a 30MH / s mining hashrate, though there's nothing to write about today, once Nvidia has cut hash percentages to half of its gaming cards, as s 'reports, RDNA 2 will look so much sweeter for miners.
