The two machines are pretty even matched.
Here is a great article comparing the two:
http://blogs.guardian.co.uk/games/archives..._they_mean.htmlAnd i quote from it:
QUOTE
The cores really place the power in the hands of developers. The Xbox 360 has 3 running at 3.2GHz each, the PS3 has seven apparently. So theoretically the PS3 is faster, much faster, which means it can do a lot more complex things. These days complex things refer to physics calculations and graphics operations. But it's all about how to use them as the power can only be exploited by using the cores together. It's a bit like having several complex puzzles to solve with several clever people available. If you give each person one puzzle will they solve it quicker than if you give all the people one puzzle at a time? The better developers will make their code efficient, meaning theoretically better games.
PS3 1, Xbox360, 0.

In terms of the active memory on access, the PS3 is two times as powerful as the PS2 and the Xbox 360 is twice that.
PS3 1, Xbox360, 1.

Now for those teraflops. The more there are, the faster the machine can do sums. In more high-tech speak, gamesindustry.biz says:
a measurement of how many of the floating point operations crucial to the graphics and physics in modern games can be processed per second
Sony wins in tech-talk on this crucial ground, with two times the terraflopping of the Xbox 360.
PS3 2, Xbox360 1.
QUOTE
With all the different processors added up, PS3 can perform twice as many raw calculations per second. In practise though, the different chips will need to wait for each other to catch up, so it will never run at full tech speed.
QUOTE
PS3 will be able to output a higher-resolution (i.e., more high definition) signal
PS3 3, Xbox360 1.
QUOTE
Sony's machine is unique in that it offers two HD outputs, for the ultimate in multitasking.
I wont score that, but it's cool.
QUOTE
Memory: Microsoft's will probably ship with 20GB - a behemoth amount (think 5,000 songs on an iPod). PS3 purchasers will have to buy their hard drive at the pay point. Both machines support memory cards. Microsoft's will be 8 times larger than PS2's current 8 MB card, but Sony's will support their SD memory sticks. More memory will come from the USB ports - a whopping six on Sony's machine and three on the Xbox 360.
I think Xbox360 gets the point for that.
PS3 3, Xbox360 2.
QUOTE
the PS3 supports more players in the same room than the Xbox 360 which only offers four.
More players, more fun. Although both machines will be primarily online, PS3 for that.
PS3 4, Xbox360 2.
QUOTE
Online: Microsoft simply has more experience with the online medium, so it's expected that their implementation of Live will be better. From what I've heard on the inside, it's definitely easier to design for.
Ps3 4, Xbox360 3.

In the end, PS3 has got it for raw power, visuals, games etc. But Xbox360 will probably rule the online world, as well as will be cheaper, in every aspect, have a better memory system etc etc.
