The big difference with the 4070 Ti Super is that it's using the AD103 chip (with a full 256-bit memory bus and 16GB of VRAM) found in the 4080, which is a huge leap over the AD104 chip found in the 4070 Ti (non-Super), which only touts a 192-bit memory bus and 12GB of VRAM.

While the TFLOPS of the Super variant does only see a ~10% increase as you note, memory bandwidth jumps by 42% and the memory capacity jumps by 33%, while the launch price is the same in my currency.

It basically bridges half the distance between a 4070 Ti (non-Super) and a 4080 (non-Super) for the same launch price as a 4070 Ti (non-Super).

Great card for memory intensive workloads like LLM inference with big context windows, IMO.

EDIT1: 4070 Ti Super TDP is 320W (same as 4080), higher than the anticipated 285W

EDIT2: launch price confirmed to be same as the 4070 Ti (non-Super), lower than anticipated!
