Performance claims[edit]
Performance-per-watt was published by Quall based on an Int8 3×3 convolution operation with uniformly distributed weights and input action comprising 50% zeros which Qualcomm says is typical for Deep CNN with Relu operators. To that end, Qualcomm says the AI 100 can achieve up to ~150 TOPs at ~12 W at over 12 TOPS/W in edge cases and ~363 TOPs at under 70 W at 5.24 TOPs/W in data center uses. Numbers are at the SoC level.
| SoC Power | 12.05 W | 19.74 W | 69.26 W |
|---|---|---|---|
| TOPS | 149.01 | 196.94 | 363.02 |
| TOPS/W | 12.37 | 9.98 | 5.24 |
