EVGA, RTX 3090 FTW3 up to 2.1GHz with manual overclock?

Obviously we don't know if these values are real or are just part of an advertising campaign. We can see earlier in the video (at 1:28 minute) that the base GPU clock appears to be 1,695MHz, with the GDDR6X memory at 9,750MHz (19.5Gb / s), matching the reference data. br>
The next segment shows the overclocked core and memory speeds and some oddities can be seen. The core clock, in fact, is 2.105MHz, but the memory runs at 5.520MHz. This would mean that the memory has been significantly underclocked (at 11 Gb / s) or that the multiplier on the RAM has changed to 4x. Neither makes much sense, which makes us wonder if this is a typo.
A 400 MHz core overclock on a modern GPU is truly remarkable, but we don't really know what the typical RTX 3090 boost clock. In the past, NVIDIA has been quite conservative with boost clocks. The RTX 2080 Ti Founders Edition, for example, has a boost clock of 1,635MHz, but typically runs at 1,800MHz or more in non-overclocked games. In other words, a static clock of 2,105 MHz may only be 100-200 MHz higher than what the GPU normally offers.
Unfortunately, we'll have to wait until September 17th to see how the RTX 3080 performs, and another week to check the performance of the gigantic RTX 3090.
