In a new post by leaker Golden Pig Upgrade, we're being told that the mobile RDNA 4 GPU offerings will arrive in two Navi 4X GPU camps: Navi 48 and Navi 44. We can expect two Navi 48-based SKUs which should materialize into a Navi 48 GPU with 16GB GDDR6 memory on a 256-bit memory bus, and a Navi 48 SKU with 12GB of GDDR6 on a 192-bit memory bus.

• R25M-E6 (possibly Navi 48) - 16GB GDDR6 on 256-bit memory bus
• R25M-E4 (possibly Navi 48) - 12GB GDDR6 on 192-bit memory bus
• R25M-P6 (possibly Navi 44) - 8GB GDDR6 on 128-bit memory bus
• R25M-P4 (possibly Navi 44) - 8GB GDDR6 on 128-bit memory bus

Under that, we're to expect two Navi 44-based mobile RDNA 4 GPUs, both with 8GB of GDDR6 on a 128-bit memory bus. The bigger difference between the Navi 44 mobile GPUs is that the "P25M-P6" variant will have a 75-150W TGP, while the "P25M-P4" variant will have a 50-130W TGP range. These new mobile RDNA 4 GPUs will launch in 2025, 2025 inside of new gaming laptops.
