MSI made at least two typos and corrections spaced apart from each other that hint at the possibility of a 24 GB variant of the NVIDIA GeForce RTX 5080. The first instance was on the side of the retail box of an RTX 5080 Vanguard OC Launch Edition, which had "24 GB GDDR7" printed on top of the RTX 5080 label. The second instance was in the VGA Support list in the product page of the MAG X870 Tomahawk motherboard, where the memory size is displayed as 24,576 MB (24 GB). There are two possible interpretations of this.

One possibility is that NVIDIA originally planned the RTX 5080 to feature 24 GB of memory, using 3 GB (24 Gbit) GDDR7 memory chips across the 256-bit wide memory bus of the "GB203" silicon, and initially communicated this to its board partners, but revised the specs in the months leading up to the launch, with the card ending up with 16 GB (8x 16 Gbit). The other possibility is that there is actually a 24 GB variant in the works, which NVIDIA could end up calling the "RTX 5080 24 GB." The RTX 5080 in the market already maxes out the "GB203" silicon it's based on, so the variant could just offer a 50% increase in memory size at the same or similar memory bandwidth. The additional memory could come in handy with 4K Ultra HD + ray tracing + DLSS 4 MFG scenarios where a gamer is looking to turn their roughly 60 FPS framerates to match the 120 Hz refresh rates of their displays.
