I was going crazy reading through all the threads and seeing people equate the GT 130 to this or that or to the other thing. The short answer is, I believe, it is not *exactly* like any of them, though as people mentioned, fairly close to the 9600GT, 9600GSO and/or 8800GS.

I just installed Windows 7 Beta and the latest beta drivers from nVidia, here's what they say:

GT 130
64 stream processors
529MHz core
1323MHz shader
792MHz memory speed/1584MHz data speed
256-bit
PCI-E x16 Gen 2 bus

Comparing with the specs listed on Techarp, it looks to me to be closest to the 9600 GT overall, but with clock speeds slowed down. Also close to the 8800M GTS on the mobile side.

But it is definitely *not* the GT 130M as some people were concerned about:

I'll be running 3DMark06 and 3D Vantage tests on it hopefully later tonight.

This is interesting, I didn't see it yesterday, direct from nVidia website:

http://www.nvidia.com/object/product_geforce_gt_130_us.html

GPU Engine Specs:
Processor Cores 48
Graphics Clock (MHz) 500 MHz
Processor Clock (MHz) 1250 MHz
Texture Fill Rate (billion/sec) 12

Memory Specs:
Memory Clock (MHz) 500 MHz
Standard Memory Config 768 MB DDR2
Memory Interface Width 192-bit
Memory Bandwidth (GB/sec) 24

- - -

Now I am fairly confused as these are not the same things I saw this morning, particularly in terms of # of processor cores (48 vs 64) and the memory interface bandwidth (192 vs 256).

I'm not sure how the computer determines what it shows you (the specs I listed in the original post were from the nVidia control panel, hitting "System detail" button), i.e. if it just spits out something generic from a database or if it's actually accessing the chip. Anyway, the plot thickens lol.

Perfect! I think there was also another forum member who keeps asking for GPU-Z tests. Maybe that will help clear up some more things in THE GREAT IMAC GPU CONUNDRUM. This also makes me wonder now if the 4850 option is NOT the mobility version.

Really it will be interesting to see where "this" chip ends up. It seems that Apple not only gets special treatment from Intel but from Nvidia as well.

Got a little extra time in the afternoon so without further ado:

3DMark06 (1280x1024 - all default settings):

9645 3DMarks
4303 SM2
3960 HDR
2804 CPU

This is in Windows 7 using the 181.71 drivers, 3.06GHz CPU.

Very respectable!! I was actually expecting something closer to the 7000 range. For reference I had an older PC system with a 2.4GHz Core 2 Duo and an 8800GTX 768MB which scored 9690 3DMarks.

GPU-Z was a bust, the card registered as a 9600GT Pre-release and most of the information was either blank or looked wrong.

Will run Vantage later tonight.

Does the discrepancy between rittchard's 3DMark06 results and those of Notebook.com mean that the iMac's card isn't the mobile version? Or did they use different testing parameters? I couldn't find on their site any more detail on that matter.

Don't tell me I am waiting 4- weeks to get something worst, for more money :mad:

Remember that we're not sure if it's the mobility version. It could be an underclocked desktop version, and I don't know how it would score. We'll have to wait for someone to get and test the radeon for an answer.

Myself, I'll just get the gt 130.

If you see at the test you'll see that the GT 130 got results close to the GeForce 9800M GTS (9692). Perhaps it's an underclocked 9800M GTS?

That would make sense. Quell people's fears that the old iMac's 8800 GS was better. The iMac's GT 130 is looking to be a very respectable card. Should play most games coming out for another few years yet, but I suspect that it would struggle to play most post-2007 games at 1920*1200 and decent detail settings.

That is very respectable! Now I'm wondering, if it's not the mobile version, how Apple fit a card requiring 350W minimum into a iMac that draws only 280W maximum...

Because that 350W minimum takes account of all the computer's components (CPU, hard drive, etc). Granted the iMac's 280W includes display also, it uses a laptop CPU which is much less power hungry (hence a bit less powerful). Essentially, everything in the iMac is more power efficient than the average PC that the 350W measurement is made for.

At this point, yes, I'm reasonably certain this is NOT the GT 130M. It is registering as a "prerelease" 9600GT. I think it's essentially an underclocked 9600 GT, *possibly* with the 55nm process(I thought I read someone speculating that somewhere?) - that might explain the power consumption discrepancy. Or maybe just the underclocking is enough to draw less power. The iMac doesn't seem to be heating up (during 3D Vantage) that much and I didn't hear any fans coming on at all, it's fairly amazing.

Also keep in mind when you compare the numbers the CPU portion will influence what you see - I believe this is a very nice CPU (E8435) so the scores will reflect that. 3DMark06 in particular seems to favor CPU considerably. However in the Vantage results...

GPU 2058
CPU 17892
3DMark P2643

If the ATI 4850 is non-mobility, it will be much much faster still (25-40%). If it is mobility, it's probably 15-20%.

FWIW though, 3dMark06 scores CANNOT be compared across different computers, so going off that website isn't enough. This is because 3dMark06 defaults to 1280 x 1024 resolution, which is VERY CPU bound. For instance, I can put a 4870X2 on a Core 2 Duo clocked at 1.86 GHz and get a ridiculously low score of 10k on my PC. Or, if I put it into my QX9650 OC'd to 4.0GHz quad core desktop monster, I score 22k on the same settings. See how a CPU change makes a HUGE difference?

Like in rittchard's example with the 8800GTX - my 8800GTX would score ~13-15k on 3dMark06 with a 3.2GHz Core 2 Quad. If he put the 8800GTX in the same CPU as the iMac, it'd probably do better than the 96xx he had with the slower Core 2.

Vantage is a beter indicator because it is less CPU bound at the higher settings. A Vantage score of P2643 is interesting. A desktop 4850, however, will score P6600~7000ish so take that FWIW.

Also, I'd like to note that GPU-Z is a database that doesn't detect what the actual card is, it just uses what the software-writer knows and puts it in there. It registering as a 9600GT definitely suggests it is a 9600GT, but it could also be that the GPU-Z isn't identifying the car correctly.

An example of this was before the RV770's were released. GPU-Z pics said 480 stream processors, but we all know now that they ended up with 800 :D

Because that 350W minimum takes account of all the computer's components (CPU, hard drive, etc). Granted the iMac's 280W includes display also, it uses a laptop CPU which is much less power hungry (hence a bit less powerful). Essentially, everything in the iMac is more power efficient than the average PC that the 350W measurement is made for

The power minimum is just what the GPU maker recommends so people don't fry their PC and sue them for not having given limits. It isn't the actual iMac components being more efficient - they use the same components as any other PC now. It's that the actual power draw at the wall that computers use are grossly overrated.

For example, a 4870X2 might say you require a 700 or 800 watt PSU. In truth, my desktop enthusiast PC, despite having twin water cooling loops, a 4870X2 overclocked, a QX9650 Quad OC'd to 4GHz, 3 hard drives, etc. only draws 450 watts total at load from the wall, using a Kill-A-Watt.

Add in the fact that I'm at 80-85% efficiency with the power supply, and my system (the components themselves) as a whole is using around 360W at most. Makes that 1000W PSU I have seem a little ridiculous, but it's a safety thing (because you don't want to draw at 80% all the time at load, it's safer to keep it at 50% for longevity).

After reading these posts, I'm really happy that I chose GT130 instead of 4850

I mentioned it in another thread allready.

GT 130 = 9600 GSO, but NOT 8800 GS

8800 GS = 8800M GTS !!!


The comparison/benchmark above is ********.

The 4850 is much faster then the GT 130!!!


And you wont be happy at all, because even the "old" 8800GS is faster then the GT 130... ;)


If you don´t believe me search for "9600 GSO" instead of "GT 130":

"9600 GSO" vs. "HD 4850"

and

"8800M GTS" vs. "9600 GSO"

Search for yourself, i think even you should be able to use google.

Knowing that a GT 130 is a renamed 9600 GSO, how can you even think it is as fast, or even faster then a HD 4850... ;)

The GT 130 is crap, get the "old" iMac with 8800 GS aka 8800M GTS or get the "new" one with HD 4850.


This is all i will say, believe me, use google to check it, or dont... i dont care.

Do you know the exact part number/model used in the new iMacs?

No you don't, so quit talking out the wrong end.

I wouldn't believe any benchmarks on the web unless they were done on iMac's with the various cards installed in them. Apple has been known to "mis-label" cards on their specs, like labeling an under-clocked HD Mobility 2600XT as an HD 2600 PRO. Until someone like Barefeats runs these various cards all on 2.93's (or a group of users do the same) I wouldn't believe anything.

Hmm, I guess the G130 seems to be a faster beast than everyone thought it would be... This is a good news. Maybe I will buy a new iMac with the G130 now instead of wating for the 4850 to arrive...

Humm, interesting. this certainly throws up another question mark in my purchasing decision.

I think in the end the 4850 will still be the faster option and for a mear $45 more I'll have to choose it. I would like to see more benchmarks though.

That is simply not true. The 9600 GSO has a 192 bit memory interface. The card in the imacs has a 256 bit memory interface. Changing the clock speed does not change the memory interface. This card is NOT the 9600 GSO.

The specs look almost exactly like a 9800M GS, for what it's worth. Same number of stream processors, same memory interface, same core and shader clock speeds, same memory speeds.

http://www.notebookcheck.net/NVIDIA-GeForce-9800M-GS.12932.0.html

It also commonly comes with 512 meg memory. Such as in the ASUS G50Vt

*edit*

Also, if you take a look at the link above, you will see that this card benchmarks slightly BETTER than the 8800M GTS, which is what apple calls the "8800 GS" in their 24" early 2008 iMacs. So the report that the new card gave better WoW performance that old top-end card is likely accurate. That being said, the cards are comparable.

Also, for my money, the 4850 will be the MOBILITY version of the card, which you can also see benchmarks for at the link above. Apple has put mobile gpus, cpus, and memory in all the iMacs in recent years since they all have laptop chipsets. Since the new early 2009 iMacs seem to have mobile chipsets since they have mobile ram and mobile cpus and mobile gpus, It is almost certain that the high end card will also be the mobility versions of the card.

Note though that per the benchmarks, this is likely the BEST card apple could have put in the iMac considering that due to space and power and heat requirements, they must have mobile chipsets and can't have 2 cards in SLI, Crossfire, or simply mushed together into one card.

If the 130GT has been demonstrated to be non-mobility then the ATI option simply can't be mobility otherwise the performance would be much slower....
