I'm not sure how much IPC gain we'll see with the new SMs tbh. The SM architecture number is incremental and not a new version number if I remember correctly, and as some people have pointed out, the warp scheduler does not appear to be wider to execute concurrently over all three FP + FP + INT banks; it's still 32 thread/clock issue if I'm not mistaken, so the theoretical max throughput is identical. Where we might see gains is data transfers, which translates into less execution bubbles.76 SM vs 70 SM is not a lot, true, but these SM are more powerful and clockspeed will be also significantly higher.
Giving the SM a 10% IPC gain, AD103 is probably 60-70% faster than the 3080.
1.1 IPC x 1.4 clocks x 1.086 SMs = 1.672
