Game's and program's system requirements are always based on desktop versions and therefore laptop users are somewhat left behind since the laptop version (ATI Mobility branch, for e.g.) perform worse than the desktop counterpart.

So the question:

What is the nearest match for the desktop version of "ATI Mobility Radeon HD 4550" graphic card (512MB RAM)? On a wider question, how you actually meter your laptop card to find a desktop equivalent?

Extra info:

According to

Compared to the desktop ATI Radeon HD 4550, the mobile 4550 features a slower core clock (600 versus 500) but can have a higher memory clock. Therefore, the performance should be more or less comparable (the mobile card will be a bit slower).

Says one thing is worse, other is better but in the end, worse than the desktop counterpart. So the true equivalent would be a 3XXX series or what?

I've read on Wikipedia about the Radeon Nomenclature, which the first number is the chipset and the second performance. But I've seen people saying that 5850 is better than 8800GT so I'm really confused. Shouldn't newer chipset, with same performance be better?

The 8800GT is Nvidia which uses a different naming scheme. – Nathan C May 24 '13 at 17:49
4550 series graphic card performs as a 4500 series graphic card. Your question makes no sense, even your quote, says it will perform about the same. – Ramhound May 24 '13 at 17:54
@Ramhound 'a bit slower' is not 'equal' thus I can't use the desktop 4550 as "equivalent" IMO – RaphaelDDL May 24 '13 at 18:38

The "mobility" series cards are lower clocked in order to reduce power consumption, so performance will be slightly degraded compared to the desktop counterpart.

By slightly, I mean probably not very noticeable especially if you overclock the card yourself to the desktop's specs.

The easiest way to compare is to run 3DMark on both chips and see which fares better.

Got any reliable source on how overclock it? – RaphaelDDL May 27 '13 at 2:44
Could try this: - your mileage may vary. Don't overclock unless you know what you're doing. :-) – Nathan C May 28 '13 at 10:55
Yeah, I just wanna test FFXIV benchmark with overclocked to see if it gets a better score. That's why I made the question. Says minimum Radeon 4770 HD but mine is a 4550 that isn't much like a 4550 because of mobility – RaphaelDDL May 28 '13 at 12:44
