Differences? 8800M GTX and 9800M GT

Anybody know? Are really really equals or should one outperform another in any way?

 

there equal

 

they are not equal, there are 0.00000001% difference.

 

well almost equal

 

lol Nirvana.
PS your new avatar is superior. and adorable.

 

Huh not at all....

The 9800M GT is a G94....64SPs... It's gonna be similar the 8800M GTS...¸probably a bit better because of high clocks but that's all...

It could be equal if it's running at ~1700mhz on the shaders/700 core but I doubt it will happen...

 

Thank you! so is yours!

 

JCMS: Donald at powernotebooks already said they were statistically equal, so I'm pretty sure they are.

 

It's possible if it's clocked really high but it still only have 64 shaders versus 96 so it would have to have 3/2 the clocks.

EDIT: Hmm, It's probably a G94b, 55nm so yeah it's possible to have it clocked at 750mhz on the core on a notebook.... I think

 

agreed i dont see how it will be the same.. maybe very close..

 

Second generation shaders (9000 series) were supposed to be 2X as efficient as first generation (8000). Maybe this is one influencing reason.

EDIT: Nirvana corrected me: 40% faster, not 2X as efficient

 

nVidia had also claimed that the 9-series will be 40% faster.

 

Whoops -- that's what I meant! It's getting late

Not 2X faster... 40% faster.

Thanks Nirvana

 

well that would be sweet if so but ill believe it when i see the benches.. nvidia and ati make lost of claims

 

The 3DMark06 results I saw about 6 weeks ago showed a very similar performance in GT vs 8800M GTX, with the 9800M GTX scoring about 25% higher. That's overall 3DMarks and bear in mind they were a while ago so production models might perform a little different.....

 

im more talking about actual fps though i dont really worry about 3dmark to much myself, also neil which did score higher?? can you tell us??

 

True. I too prefer more real-world FPS comparisons.

Either way, both cards are solid. Although now I have to try and resist the itch to upgrade to the 9800M GTX... just because "it's there". And it's better. Haha.

 

so 9800m gtx is not a die shrink after all?

 

Soz, I meant 9800M GTX scoring higher than the 88GTX. I realise 3DMark isn't an accurate real world fps guage but it does show comparative performance.

 

okay...
so if the 8800gtx performance is pretty much equal to the 9800gt,
how are you guys going to decide one over another?
does one run cooler or something? argh....

 

You cant decide one over the other the 8xxx series arent offered anymore. And the both have the same thermal properties.

 

No need to decide because 8800m GTX is not available.

 

Your specs are pre-release and not accurate for the released product.

 

Well, that was easy.

 

holly crap... i just noticed the launch is...alrdy launched...
okay.... then. wow.
im still interesting in how the 9900gt offered stacks up with the 8800 gtx. hopefully at least lower power consumption?
and what pcmw is gonna do lol..

 

where are the official specs btw for the gt and gts?

 

ok im cornfused....
the title says 9800M GT, but there were references regarding 9800M GTX...
did i miss something?
i thought we wanted compairisons (sp) from 8800M GTX and 9800M GT(S)

 

The reference to the 9800mgtx was the % increase from the 8800gtx.

 

a 9900gt is 2.5 times " faster" than 8800 gtx

 

Thread subject: Differences? 8800M GTX and 9800M GT

Answer...no, not so you could tell. Not in performance, power consumption or heat. Any differences are statistically insignificant.

 

nvidia does not even have spec comparisons on thier website....

 

Perfect answer : ) Thanks man.

It's 2 in the morning, I work at 6, and I'm too excited to sleep. A grown man acting like a 5 year old kid on Christmas eve.

 

So basically, the only difference is that the 9800m GT supports PhysX and CUDA, but it is possible in the future that the 8800m GTX will support those too. So it may be possible that there are NO differences between the two cards?

 

8800m has been confirmed for supporting PhysX

 

9800m GT maybe be a better OC due to Shader Optimization 2.0 ?

 

what is different between 9800m gt vs 9800m GTX?
they the same? i am so confuse...

 

different core, different memory, different SP.........different name

 

im not sure, but i think the 9800m gt has 96(out of 128) shaders and 48(64) texture 16 raster and the 9800m gtx has 112(128) shaders 56(64) texture 16 raster.
and i think the 9800m gtx is clocked a little bit higher.

 

noticed that the 9800MGT is offered in SLI and 9800 GTX isnt.

If u get an 9800 GTX, percentage wise what would be the difference?

Which config is optimal?

 

So when does PhysX support arrive for Geforce 8800M GTX ?

 

Driver differences? 9800 GT is very new, therefore we'll all have to wait a few months before a stable driver is released

 

Sorry. But this is not true. nVidia maked very small changes between the g80 and g9x GPU's series. The biggest one was that the G9x GPU's have the same ammout of TMUs and TAUs. At the G80 GPU there was a ration of 2:1 for the TMU's. There were only some small modifactions on the shader units. The G84 and G86 GPUs were the first one with that changes.

The 8800M GTX was already based on a G92. The same GPU is used for the desktop Geforce 9800 GTX . The 9800 GTX+ ist based on the G92b, which is only a die-shrink from 65 nm to a 55 nm manufacturing process.

So there will be no difference in the shader efficiency per SP unit between this cards.

 

The whole architecture of the G9x GPUs ist already very old. The first G9x (G92) card come already last year on the market and ist was only a minor modifaction of the G80 architecture. So the drivers should be already very good for every card based on this architecture.
The 9800 GT is not a new architecture.

 

I have read that the 9800m GT is likely to be more comparable to the desktop 9600 GT than the 8800m GTX, due to the architecture.

Would that be an accurate statement?

 

For frist. nVidia and ATI doesn't develop since a long time "special" mobile GPUs. They simple preselect the best GPUs from the same GPUs which are used on the desktop cards.

For example, the 8800M GTX uses as GPU the G92. The same GPU is used on the desktop 8800 GT and dekstop 9800 GTX. In some cases they then deactivate some units of the GPU to get better power consumption and thermal buget. For the 8800M GTX for example a whole block of shader units is deactivated.

How the 9800M GT performs depends which GPU ist used and how many units, like shaderblocks, of the GPU are used and how high they clock this card. There are two (four) possible GPU whiche the 9800M GT uses: G92(b) and G94(b). "b" suffix means only a die-shrink to 55nm manufacturing process and no other changes were done here.


If the 9800M GT is based on the G94(b) the perfomance will be very comparable to the desktop 9600 GT cards since they use the identical GPU and I don't belive they will deactivate units. If it is based on the G92(b) the question ist how much units they will deactivate. In both cases the question is also how high clocked the card is.

Vr-zone and other sources had reported that the 9800M GT will be based on the G94b. So the perfomance would be comparable to the desktop 9600 GT

 

Thanks, that was very informative.

 

so how is the desktop 9600gt compared to the 8800m gtx performance wise??

 

I'm not au fait with the performance of the desktop 9600GT - so would you agree with Donald's previous sentiment that the performance of the 9800M GT is not meaningfully different from the 8800M GTX?

Many thanks,

Petrov.

 

Please remember, we said " nvidia had claimed" and " up to 40%". we are telling whatever nvidia told us, no ones on this forum had said there will be actual 40% difference.

 

According to specs the 8800gt (desktop) 600/1500/900 has 48 more stream processors than the 9600 gt 650/1625/900. But the 9 series has better shader optimization which might account for lower stream processors.
