The rumored specifications on NVIDIA's next-gen GeForce RTX 40 series graphics cards are running hot today, with the latest leaks pulling up the GDDR6X memory bandwidth on the GeForce RTX 4080.
NVIDIA's new GeForce RTX 4080 rumored specs haven't changed much, with leaker "kopite7kimi" teasing the AD103-300-A1 GPU and 420W of TDP -- unchanged rumored specs here -- but the 16GB of GDDR6X is reportedly being cranked up to 21Gbps, up from previous rumors pegging it at 18Gbps.
The current-gen Ampere-based GeForce RTX 3080 in its original 10GB GDDR6X (not in the second "LHR" Lite Hash Rate version) form saw the 10GB of GDDR6X memory clocked at 19Gbps. NVIDIA's new GeForce RTX 4080 graphics card with 16GB of GDDR6X memory at 21Gbps is a better rumor to hear, up from the 18Gbps GDDR6X (lower clocks than the RTX 3080).

NVIDIA is reportedly dropping the GeForce RTX 4080 and its 16GB of GDDR6X memory at 21Gbps on a lower 256-bit memory bus (the RTX 3080 10GB has a 320-bit memory bus) which drops the RTX 4080 down to 672GB/sec of memory bandwidth, down from the 760GB/sec memory bandwidth on the RTX 3080 10GB.
