pyCUDA vs C performance differences?

Question

I\'m new to CUDA programming and I was wondering how the performance of pyCUDA is compared to programs implemented in plain C. Will the performance be roughly the same? Are the

If you're wondering about performance differences by using pyCUDA in different ways, see SimpleSpeedTest.py included in the pyCUDA Wiki examples. It benchmarks the same task completed by a CUDA C kernel encapsulated in pyCUDA, and by several abstractions created by pyCUDA's designer. There's a performance difference.
