Yes, there are several computer chess rating lists, but you run into the same problems once you want to compare a CPU engine with a GPU one: how do you account for the hardware? Really a rating, as a measure of playing strength, should apply to a hardware/software combination, but we almost always want to compare the software. The most respected lists used to be the SSDF [0] and CCRL [1] lists but they both ignore the GPU issue. There's now the CEGT list [2] which I don't know anything about, but does seem to use heterogenous hardware. Note that the numbers aren't calibrated to human players, so there's no claim that an engine with a rating of 3100 on some particular hardware should score 85% against a human rated 2800, or whatever.
