Gigabyte is soon going to release the Radeon RX 7900 GRE graphics card. This features 16GB of GDDR6 Memory and has a 260W TBP (total board power). The specific GPU variant (not specifically the Gigabyte model) is also seeing wider availability outside of China. There is no information on specifications or pricing of this particular Gigabyte RX 7900 GRE graphics card for now.
Radeon RX 7600 XT will launch in 'first half of 2024' as per the new leak. The source also claims no other AMD GPU is planned. EEC filings mentioning this GPU and several others have been spotted, but Benchlife's latest report states only the RX 7600 XT is coming and it will complete AMD's Radeon RX 7000 Series RDNA 3 lineup.
