While CPUs use large caches and complex logic to minimize latency for sequential tasks, GPUs use massive parallel arrays to maximize throughput for parallel workloads. However, the ultimate performance killer is data movement latency across the PCIe bus between the CPU and GPU; for small workloads, this transfer time completely eclipses the actual compute speed.
