Leaks suggest the mobile RTX 5090 will see significant memory improvements over the mobile RTX 4090, though it will differ from the desktop RTX 5090. While initially expected with 16GB of GDDR7 (matching the mobile 4090), the use of new 3GB GDDR7 modules could enable a 24GB configuration, matching the desktop RTX 4090's VRAM. This increase was previously impossible due to the lack of suitable GDDR6 modules.
Here's a breakdown:
Memory Technology: A key upgrade is the shift to GDDR7 memory, offering substantially higher bandwidth than the GDDR6 in the mobile 4090 and the GDDR6X in the desktop 4090.
Potential VRAM Increase: The rumored 3GB GDDR7 modules could allow for up to 24GB of VRAM on the mobile 5090, matching the desktop 4090. The initial launch is still expected to be 16GB.
Bandwidth Boost: Leaks point to GDDR7 speeds of 28 Gbps, a significant jump from the mobile 4090's 18 Gbps, crucial for high-resolution gaming.
Different GPU Die: The mobile RTX 5090 will likely use the GB203 die, unlike the desktop RTX 5090's rumored GB202.
Reduced CUDA Cores: The mobile version is expected to have around 10,752 CUDA cores, significantly fewer than the desktop 5090's rumored 21,760.
Power Consumption: The mobile RTX 5090 is expected to have a higher TDP of 175W.
In essence, the mobile RTX 5090 focuses on a substantial memory bandwidth increase with GDDR7 and the potential for matching the desktop RTX 4090's VRAM. However, it will have a different GPU die and fewer CUDA cores than the desktop RTX 5090.
