At least the top model
Possible frequencies for the Nvidia Ampere video card based on the top GPU GA102 have appeared on the Web. Presumably, we are talking about the GeForce RTX 3080 Ti.
According to the data, the core will operate at frequencies above 1485 MHz (base) and above 1740 MHz (boost). For comparison, the reference RTX 2080 Ti is clocked at 1350-1635 MHz. That is, the minimum frequency increase of the new card relative to its predecessor will be 135 and 105 MHz, but it can be even higher. True, we know perfectly well that at least the declared increased frequency of modern video cards is a very conditional concept, since in reality adapters often operate at higher frequencies, and they depend on many factors.
The source, in this case, is the insider program, who often pleases with such data. For example, it was he who back in February provided data on the Core i7-1068NG7 processor, which will be used in the new MacBook Pro 13.
