If the data is already in GPU memory, yes. Otherwise you'll be limited by the DRAM<->VRAM memory bottleneck.
When we consider that delta coding (and family), are typically applied as one step in a series of CPU-first transforms and benefit from L1-3 caching we find CPU throughput pulls far-ahead of GPU-based approaches for typical workloads.
This note holds for all GPU-based approaches, not just PTX.
