Go up one level in this thread
I do not think that today a graph like that would be relevant. Some programs sacrafice plies for a much more thorough evaluation. Other programs sacrafice a thorough evaluation for speed. If you had a chart like this, a program that searched slow would but evaluated well would do very well on a chart like that, while a fast program that didn't have as complex evaluation would do poor. But if you actually had a match between these two programs they two extremes would probably even out.
