Clockspeed-wise, yes, but in otherall horsepower etc. it probably is not. Regardless of the technical details MOST developers/publishers/press say that the difference in power is extremely small and negligible, so it's probably why when developers/publishers/press ever make comparisons between 360 and PS3 power they usually default to the usual "360 is easier to make games for and is really powerful, but the PS3 is capable of much more due to the CELL. We will soon be able to take games further than what the 360 can do as development learning curve on PS3 gets easier."
Which is my feelings on the matter.
I think we can all at least be pleased that many PS3 games currently are just as beautiful as their 360 counterparts, although with small visual glitches here and there as well as frame rate issues. But seeing as the 360 has been out for a year longer than the PS3, I would say that being on par with a console that's been out a year longer is a good sign that it's soon going to surpass it.

Shader Model

the only place where the RSX wins is in pixel shading power, yet these numbers don't take into account the huge amount of extra muscle the cell architecture adds to the equation.
to the other poster yes I am very familiar with reviews and opinions that either say graphics are the same on both systems or even more absurdly "better" on the 360.
I am viewing both outputs at 1080p and the PS3 wins everytime out. If i was just another dummy stating his opinion with no qualifications I would say listen to the reviews, but since I have4 been working with graphics and color since the age of 13(im now 35) I think I can trust my own trained eye to tell the difference.
