New day, new RTX 40 specs

The embargoed RTX 40 specifications for board partners certainly do change a lot. Hardware leaker Kopite is reporting on any change to the SKUs being considered for the upcoming models. 

Following an update to RTX 4090 and RTX 4070, the RTX 4080 is now in line for an update. It should be noted that RTX 40 specs did change a few times before; the most recent update for RTX 4080 was around June. Kopite has since updated the RTX 4090 and RTX 4070 specs, with the only remaining part being 4080.

At least in this case the specs did not change dramatically. There is only an update to CUDA Core specs, now rumored at 9728. This means a downgrade from 80 active Streaming Multiprocessors to 76. The memory, TDP and performance estimates appear to be the same.

The RTX 4080 requires 420W of power by default and should ship with 16GB 256-bit GDDR6X memory. Judging from new specs, all thus far confirmed high-end RTX 40 models are to feature 21 Gbps modules.

Kopite did not update the 3DMark TimeSpy Extreme score (as he said before those are not estimates but actual test results). This means that with fewer cores, the clock speed might have gone up, although we do not know the original and current frequency.

The RTX 4080 is expected to be announced at the same time as RTX 4090 which is probably early October.
