Its definitely getting more usable with each generation but still not at the performance level during general use as an old i5 mini pc or N100. It always feels to me that there's a bottleneck with the Rpis that hold it back more than the cpu benchmarks suggest.

- jpc0 2y agoIn my experience memory is very slow on the RPis... I'm talking factor if 10 improvements by getting rid of copies. For video decoding on the GPU, processing on the same GPU memory in place and then displaying takes significantly less work than decoding on the CPU copying to the GPU and doing the rest their and most of the time is in the copy.
