PC Spec Question

Am i right in thinking that my AMD Athlon 64 x2 4200+ processor at 2.1GHZ is actually 4.2Ghz as it is dual core?

If not and it is still 2.1Ghz does that mean that my P4 2.8Ghz PC is actually a better pc to use?

Im trying to work out what is best to use in my mame cabinet and desktop.
My mame cabinet is currently running the Pentium 4 2.8Ghz PC with 2GB ram and onboard grafix and Win XP 32Bit
My desktop is currently running the Athlon 64 x2 4200+ processor with 4GB ram and Saphire 2600HD Pro ATI 512mb Grafix Card in the PCie socket.

If i keep the P4 as my mame pc will i get any performance boost if i put the grafix card from my desktop pc into my mame pc? I dont play High Spec PC games but play things like hamsterball, nulldc, psxe and obviously mame which its not doing a too bad a job at runnking at the mo with not much slow down. I dont tend to play the CHD games but would i be able to with the grafix card as its not really being used in my desktop as the desktop is used mainly for downloading,emailing and internet NOT gaming. I also use the desktop as a media server for my ps3.

Not necessarily.  It's not all about clock speed.

Can you please xplain why?


newmanfamilyvlogs:

Different processors do work differently. Newer chips will be faster at most tasks that older chips at the same clock speed.

Other things that come into play with that comparison is that your X2 is a dual core chip, which MAME can leverage with multi-threading, allowing it to more work per clock. Another advantage is that you have the option to run a 64bit operating system. 64bit versions of MAME show speed advantages versus 32bit in most (all?) cases.
