The big news to me is that the top card features a 320 bit memory bus, which should offer much better memory bandwidth than the previous generation (256 bits).

The big news to me is that the top card features a 320 bit memory bus, which should offer much better memory bandwidth than the previous generation (256 bits). Assuming a linear scaling, we should see a 1.25 improvement compared to the previous generation.

RTX 2080 is 352 bits, and RTX Titan is 384. Nvidia has always had high bit rate memory bus. The one that had 256 bit was AMD Radeon GDDR. Arguably bit bandwidth is meaningless without looking at actual memory type, or the total bandwidth from memory.
- zrav 7y agoIndeed, seeing that there's also Radeons with 2048 bit bus for HBM.
- RealStickman 7y agoActually the RTX 2080 has only 256bit. https://www.techpowerup.com/gpu-specs/geforce-rtx-2080.c3224 https://www.techpowerup.com/gpu-specs/geforce-rtx-2080.c3224 The 2080 ti has 352bit. https://www.techpowerup.com/gpu-specs/geforce-rtx-2080-ti.c3305 https://www.techpowerup.com/gpu-specs/geforce-rtx-2080-ti.c3... Interestingly, Nvidia decided to use a bigger die (relative to other dies in the family) for the 3080 than for the 2080. TU104 (2080) vs GA103 (3080). Probably to prepare for big Navi.
