Comparative Analysis of FPGA and GPU Performance for Machine Learning-Based Track Reconstruction at LHCb
Using hls4ml, the authors estimate an Alveo U250 FPGA can process the LHCb track-embedding MLP at 1.1 million events per second, exceeding the measured 0.82 million events per second of an RTX 3090 GPU at lower power.
