The first set of leaks came from a Twitter user, KittyCorgi, which talks about two new specific Amper GPUs from Nvidia, the GA103 and the GA104, which sound a bit strange considering Nvidia's usual GPU naming scheme.

This information got a follow up from MyDrivers site, suggesting that the GA103, which should be behind the high-end RTX 3080, could pack 60 SMs (Streaming Multiprocessors), for a total of 3840 CUDA cores. The leak also said that the GA103 could pack a 320-bit memory interface, leading to 10GB or 20GB memory configurations.

The GA104, which should power the RTX 3070, is said to feature 48 SMs, for a total of 3072 CUDA cores. It could end up with a 256-bit memory interface, leaving it with 8GB/16GB memory configuration.

Of course, you should take this information with a grain of salt and, hopefully, Nvidia will give out more information as well as confirm its new roadmap and Amper GPUs at the GTC 2020 event scheduled to kick off on March 22nd.

One of those sources, which were neatly arranged by Videocardz.com, also had an alleged die diagram for both GPUs.
