This report synthesises findings from 14 peer-reviewed papers addressing the following research question: How does the throughput advantage of encoder-decoder SLMs over decoder-only models vary when evaluated on code generation benchmarks like HumanEval across different hardware accelerators. 11 claims were extracted from source literature; 10 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 8.5/10. This report is a machine-generated literature synthesis and does not constitute original research.Research goal: How does the throughput advantage of encoder-decoder SLMs over decoder-only models vary when evaluated on code generation benchmarks like HumanEval across different hardware accelerators?Autonomous literature synthesis.
