Rumor mill: We’ve been listening to numerous rumors about Nvidia’s upcoming RTX 4000 collection, although most of them appear to revolve across the RTX 4070, its Ti variant, and the RTX 4090. The newest declare to come back from a daily leaker includes the high-end-but-not-quite-flagship RTX 4080, which seems like will probably be an absolute beast of a card.
As traditional, the brand new Ada Lovelace rumor comes from the Twitter account of prolific and correct (when it got here to Ampere) leaker Kopite7kimi (by way of VideoCardz). They posted what are claimed to be up to date specs for the RTX 4080, with the numerous adjustments referring to the reminiscence pace and the cardboard’s TDP.
It had been anticipated that the RTX 4070, 4080, and 4090 would use 21 Gbps GDDR6X modules—they had been talked about on this month’s replace on Micron’s web site—however the RTX 4080 is now thought to function 23 Gbps speeds. Assuming the rumor is correct, the RTX 4090 will doubtless function the identical 23Gbps GDDR6X.
Let’s make some updates.

The subsequent revised spec is the RTX 4080’s Total Board Power (TBP). This is one space that leakers appear to vary each different week. It was initially stated to devour a monstrous 450W, however that was lately modified to 320W. According to Kopite7kimi, Nvidia has elevated the RTX 4080’s TBP once more, albeit by simply 20W, leaving the brand new quantity at 340W. For comparability, the RTX 3080 Ti Founders Edition has a TBP of 350 watts.
The remainder of the RTX 4080 specs stay unchanged: an AD103 GPU, 9,728 CUDA cores, and 16GB of reminiscence throughout a 256-bit bus.
Another a part of the August replace on Micron’s web site was an inventory for twenty-four Gbps GDDR6X. It may find yourself in what’s considered a brand new Titan card that was beforehand rumored to pack 48GB of VRAM, 18,176 CUDA cores, and an 800 TDP.
Nvidia experiments with the specs of its upcoming playing cards because the launch dates draw nearer, which is why they appear to vary so usually; we would not see the ultimate, locked-in specs till the launch is on the doorstep. The excellent news is that day is now simply a few months away.
