NVIDIA Next-Generation GeForce RTX 3080 and RTX 3070 “Ampere” Graphics Cards Detailed

It is expected that NVIDIA will launch their next-generation Ampere graphics cards sometime this year. They will be likely announced at GTC 2020, which takes place on March 22nd. The latest rumors have been swirling around the web about these upcoming cards with their die configurations being detailed. These new cards will make use of the 7nm manufacturing process from Samsung, which will give these cards a big improvement over the previous generation.

The two dies that have been leaked have codenames GA103 and GA104 for RTX 3080 and RTX 3070 respectively. One thing to notice is the increase in the Streaming Multiprocessor (SM) count. The smaller GA104 will have as many as 48 SMs, which means it will have 3072 CUDA cores. The larger GA103 will have as many as 60 SMs, so it would have 3840 CUDA cores. The increase in SMs should mean better performance across the board.

Along with these increased SM counts there is a new memory bus width. The smaller GA104 die (RTX 3070) will use a 256-bit memory bus allowing for 8/16GB of GDDR6 memory. The GA103 (RTX 3080) has a 320-bit wide bus which can be configured with either 10 or 20GB of GDDR6 memory.
