From these data it is not clear to me wy the GT130 is faster, alle specs except the amount of memory is better on the 8800GS !!!!! Can an expert in video cart explans this to me


8800GS GT130
core clock 550 500 MHz
shader clock 1375 1250 MHz
memory clock 800 500 MHz
memory amount 384 512 MB
memory interface 192 192 bits
memory bandwidth 38.4 24 GB/s.
texture fill rate 26.4 12 billion/s.
 
But the 2008 Imac's 24"/3.06 GHz had the 8800GS wheres the later ones (late 2009) have the GT130. It seems odd to me that in time the iMac was downgraded !!!

Absolutely. Look up them on notebookcheck (the 8800GS is actually an 8800m GTS). The GT120/130 cards are a disappointment, IMO. In almost every game, the 8800 beats out the GT130, sometimes by a wide margin.

Welcome to the world of Apple and the upside down logic it applies sometimes. Notice that the GT120/130 did not last very long as options. Maybe Apple was promised more by nVidia than could be delivered.
 
Niklaas, sorry, I understand this subject is beat to dead for you but I am new to MAC's. So what brand is the GT130 if it is not a NVIDIA, very confusing to name it the same. The url's you sent me too are to difficult to understand for me. So can you explain for a newby what the difference is in speed. I will be doing FCS, AE, Motion and PS and using AVCI as codec. Which do you think suits best for these applications??


edit : accoording to the nvidia site the GT130 exists !! : » NVIDIA GeForce GT 130M


Die GeForce GT130M ist eine höhergetaktete 9650M GT welche jedoch einen etwas geringeren Stromverbrauch aufweist (dank 55nm). Je nach verbautem Speicher unterstützt unterstützt sie einen Takt von bis zu 600 MHz (DDR2) oder 1066 MHz (DDR3) und ist dadurch auch unterschiedlich schnell. PhysX wird nur in SLI Notebooks unterstützt.
600 MHz, 32 - unified, DX10 | 1066 MHz, 128 Bit

Again.... ! The GT130 in the Imac is not a Geforce GT130 !
It uses an G92 chip, witch means the card is an Mobility 8800 or 9800 GT/S.
Go into windows and compare the card specs with the infos on this site http://www.notebookcheck.com/Vergleich-mobiler-Grafikkarten.358.0.html and you will find out .....

And..... to finde Gt130 ( how you call it ) benchmarks, check out http://www.barefeats.com/imac09.html its a little bit faster than the 8800 because its nearly the same card

Okay..... So you know now that Apple uses MXM cards ( smaller versions of desktop cards ) in there Imacs. These cards are a little bit slower than there desktop versions.
Apple thinks " he, let´s calculate this difference for our customers and rename the cards with relevant desktop card names witch should be as fast as our mobility cards! "

This is in my eyes very inaccurate and leads to much confusion at the users.

So your Geforce GT 130 .... is in fact a Mobile Geforce 8800GTS or 9800GTS ( i´am not sure witch one of these , but they use the same chip, so never mind )
What means that in speed ? hell! ... i sent you the link !!!
Your Geforce GT130 ( in fact a Mobile Geforce 9800M GTS ) is a very fast Mobile card ! its almost identical with the Card used in the Imac that says Geforce 8800GS ( in fact Mobile Geforce 8800GTS) and its even a bit faster ...........................!!!! .

Hmmm you are even more ignorant then me because it is not a notebook cart!

amazing how rude/arragant people have become. This is why I dont post much anymore, people cant even do a simple google search.

A shame. Good luck though!
 
I don't understand why everbody reacts so irritated. I have to choose between 2 used 24" imacs. The only difference is the graphics card. So I was only wondering which would be the best option.

yes so go ant get this ati card its the better one

and the amount of ram a card has is not comparable with another card just like that

its like if i would compare my iMac g3 with a iMac g5 and say they are equally fast as they have the same amount of ram , you will find 256 mb cards that leave other 512 mb cards behind in processing power
and ALL depends what you want to use your iMac for
sometimes is less more
