AMD is expected to launch the first Radeon RX 7000 series graphics card sometime in October or November, but there have been conflicting rumors about the exact specs of the new card. Official information about the RDNA 3 architecture is also limited. AMD says its upcoming GPUs will have a 50 percent performance per watt uplift when compared to the current generation, mostly afforded by a transition to a 5nm process technology from TSMC.
The company also confirmed rumors that RDNA 3 hardware will feature advanced chiplet packaging, Infinity Cache, and a redesigned compute unit. The flagship RX 7000 series GPU (Navi 31) was previously rumored to have 16,384 stream processors spread across two Graphic Complex Dies (GCDs). Recently, leakers have been posting a different story — only 12,288 cores contained in a single GCD. This could be a last-minute design change or a sign that leakers have been fed old or incorrect information. That said, Greymon55 says there may still be a separate GPU with 16,384 stream processors in the works, although it’s not yet clear whether it will be a consumer product or a workstation graphics solution (like a Radeon Pro card). Either way, this is expected to carry a Navi 3X moniker and will likely arrive sometime in 2023. If it’s not a gaming card, AMD may have decided to test the dual-GCD configuration in workstation hardware before eventually using it in consumer Radeon products, possibly as soon as RDNA 4 (Navi 4X).
