GPU-Z screenshots may show specifications for AMD Radeon RX 6600 video cards with Navi 23 GPU. Information has also emerged about the Navi 24 GPU, which can be used in a low-profile video card.
AMD will use the Navi 23 GPU in the Radeon RX 6600XT and RX 6600. With the XT variant, the GPU has 2048 stream processors with the regular version, part disabled, bringing the number of stream processors to 1792. Both cards have a capacity of GDDR6 memory 8 GB and 128-bit memory bus.
The specifications are in the GPU-Z screenshots that In the Chinese forum Chiphell Has been published. It cannot be said with certainty whether the screenshots are original, but the specifications are consistent with previously leaked details and rumors. The source claims the cards are in their possession and that they have made it work with a driver that supports the RX 6600M GPU.

Details have also emerged about what is believed to be AMD’s Navi 24 GPU. Linux drivers contain references to the RNDA 2 GPU codenamed Beige Goby. It will have a 16MB L3 cache and according to previous rumors, the Navi 24 GPU will have this much cache. VideoCardz writes. Details in the driver indicate that the GPU will have a maximum of 1,024 cores, or half of the Navi 23. The GPU will be combined with 4GB of GDDR6.
