An Athlon XP 2400+ performs similarly to a 2.4GHz P4, yes.
So if a game requires a '2.4GHz processor', an AXP 2400+ should be sufficient.
Raw clockspeed, i.e. MHz/GHz is no longer the most significant factor in terms of performance - radically different architectures such as that of an AMD Athlon XP or Athlon 64 and an intel Pentium 4 cannot be compared by simply comparing raw clockspeed.
In order to facilitate comparability of different Processors according to their performance(NOT raw clockspeed), AMD introduced a 'Quantispeed
' ">http://www.amd.com/us-en/asset...31B_Quantispeed_wp.pdf'-rating for their processors.
Since an Athlon XP or Athlon 64 can do more work per clock-cycle than a P4, it will perform about equal to or even better than a much higher clocked P4 - hence the xxxx+ rating.
This is because basically, intel's 'Netburst'-architecture(what the P4 is based on) sacrifices efficiency in order to be able to attain high clockspeeds.
In most cases, an Athlon XP xxxx+ should perform equal to or better than a P4 clocked at the corresponding figure in MHz(e.g. an AXP 2000+ performs about equal to or better than a P4 2.0GHz(=2000MHz)) - an Athlon 64
will usually outperform
a P4 with a corresponding figure in MHz.
Actual performance depends on the application you're running...for example, an AXP will perform better than a comparable P4 model in most games, whereas the P4 will perform better in some media-encoding and rendering applications since a lot of them are optimized for its architecture.Here's

It's the latest version for the Athlon 64-line - it will give you an idea about how this rating works.
