According to Benchlife, the Radeon RX 7600 XT won't be coming in a reference version, but rather left for AMD AIB partners to design their versions. The rumored launch date of January 22nd, also puts it head to head with Nvidia's launch of Geforce RTX 4070 Ti Super, although we expect it to compete with the likes of RTX 4060 or RTX 4060 Ti in the best-case scenario.
Unfortunately, there are no specific details about the actual specifications, but earlier rumors suggested that there could be two versions, with 10GB and 12GB of VRAM, and AMD will most likely go for a cut-down version of the Navi 32 GPU as the RX 7600 already maxes out the Navi 33 GPU. The RX 7600 XT could most likely end up with around 40 CUs, leaving it with 2560 Stream Processors and fit well between the $269 RX 7600 and the $449 RX 7700 XT.
Earlier EEC listings also suggested that AMD could be working on non-XT versions of the Radeon RX 7800 and the Radeon RX 7700 but there were no further leaks.
