It is obvious that Nvidia is working hard to get its upcoming Geforce RTX 40 series ready for launch and it is not a big surprise that specifications are changing.
The latest rumor coming from @kopite7kimi over at Twitter (via Videocardz.com), suggests that Nvidia RTX 4080 could come with faster 23Gbps GDDR6X memory, a decent increase compared to the previously rumored 21Gbps. The same rumor also suggests that the total board power (TBP) has been lowered to 340W.
The rest of the specifications remained as rumored earlier, so the RTX 4080 should end up based on AD103 GPU with 9,728 CUDA cores and 16GB of GDDR6X memory on a 256-bit memory interface.
Let's make some updates.

The latest rumor could also mean that the flagship RTX 4090 could end up with the same faster memory and more things could change before we see the official launch of the Geforce RTX 40 series.
