Leaked Document Shows NVIDIA GeForce RTX 4090 Production Is Well Underway
By all accounts, the first GeForce RTX 4000-series card that we're likely to see is the RTX 4090. That's backed up by today's leak, which appears to be a couple of shots from a production log at an add-in card vendor. Thanks to the close cropping of the image, most of the information has to be inferred, but it appears to show four batches of RTX 4090 cards slated for production on August 16th.

Another curiosity of these images is the presence of blanks in the "capacity/H" column, which you can see if you click on the first leaked image above to expand our crop. We're not sure what that column would indicate—perhaps production capacity per hour? It's possible that the blanks there are simply present because this manufacturer hadn't previously built any RTX 4090 cards and thus doesn't know how quickly it can make them.
The last column on the sheet, which is cut off, indicates when the cards would be ready. We can't see the date, but we can see that it says August, which means it's possible that we could see a physical launch as soon as the end of next month.
