Possible GeForce RTX 4070 "Ada" Specs Hit the Rumor Mill

Two sets of possible specifications of the upcoming performance-segment NVIDIA GeForce RTX 4070 "Ada" graphics card has hit the rumor-mill, according to kopite7kimi, a reliable source with NVIDIA leaks. The first set of specs sees the card feature 12 GB of 21 Gbps GDDR6X memory (possibly over a 192-bit wide memory bus), as many as 7,680 CUDA cores, a typical board power of 285 W, and an internal SKU code of "PG141-SKU340/341." It makes sense for 12 GB of memory across a 192-bit memory bus to be a logical choice for NVIDIA (as opposed to the previous-gen RTX 3070 with its 8 GB of 14 Gbps GDDR6 across 256-bit); as it allows the company to achieve a 50% memory size increase gen-over-gen, while reducing the number of memory chips on the card from 8 to 6 (by using six 16 Gbit GDDR6X chips).

The second set of specs doing rounds is the "PG141-SKU336/337," consisting of 7,168 CUDA cores, 10 GB of 21 Gbps GDDR6X memory across what we're assuming could be a 160-bit wide memory bus (five memory chips), and 250 W typical board power. The same source also claims that the SKU340/341 could have a performance target of over 11000 points in Time Spy Extreme, while the SKU336/337 could be designed with at least 10000 points in mind. It's quite possible that the second configuration is that of the RTX 3060 Ti-successor SKU. Given NVIDIA's top-down approach to product launches, we could expect performance-segment SKUs only toward the end of 2022, or early-2023.
