8700gt DDR2 vs 8700gt DDR3 vs sli 8700gt DDR2 vs sli 8700gt DDR3

So, can anyone tell me/estimate the performance difference of:

8700gt DDR2

vs

8700gt DDR3

vs

sli 8700gt DDR2

vs

sli 8700gt DDR3

 

there are no ddr2 8700gt's.

 

Are you sure?!?!? Ooops

 

8700GT will perform with 15-20% less power than the 7950GTX, and the 8700GT SLI will outperform the 7950GTX single card by about the same ammount, 15-20% , but with DX10 support. However note that 8700GT is a performance to high end video card, having the 128 bit ring bus. Until the 8700M Ultra will be released, the 7950 is still king of the hill. I would highly recommend the 7950 now, and upgrade to the 8700M ultra later(or whatever the name of the high end geforce 8M series will be).
Cheers.

 

would the step-up program work with the 7950gtx?

 

Well.... how do I upgrade it? Im not a real MXM pro... What laptop do you recommend? Im looking at dell.com the new XPS M1730... but its way over priced for me right now

 

Well the Alienware m9750 is a 7950GTX laptop and is awaiting 8700M GTs in October and maybe more later...
If ya don't want SLi there's always the Clevo m571RU

 

M9750 with 8700gt sli?!?!! or single?

Probably starting at $2600 so im not really interested... unless it beats the M1730 dell... But dell has a serious package going for some medium overpriced lappies:

$2999: 2.4 c2d, 8700gt sli, 7200rpm 200gb hdd, ageia 100m physics processing unit, akward casing, then theres a $3000 something version and The $4000 something version which is pretty impressive too

 

The m9750 has two MXM-III slots, so their's no technical reason why it couldn't have SLI'd 8700M-GT's. Whether or not Alienware will implement this as a factory option is unknown.

The XPS M1730 deal is okay if you absolutely need that kind of performance, however for most gamer's you can find a better value in a $1500 single 8700M-GT machine.

 

The AW starts at $1800 with a 7950GTX although you'll need $2200 to get it with a decent processor and HDD... Then again the 8700M GT is cheaper than the 7950GTX...
Don't forget that the $3000 XPS has 256MB VRAM

 

Look up the Sager 5791. Mine was about 2200 with the following specs :
2.2 Core2Duo t7500
512 nvidia 7950GTX
120 5400RPM Hdd
WUXGA 1920x1200 17' screen.

If you can go without the screen and stick to a 'matte' you could beat the 2k limit.

That is what I thought too, but now it seems that Toshiba and Best Buy have listed on their sites and stated that the 8700 that comes on the x205 that Best Buy sells is DDR2 which is clocked at 700 mhz. The only people that can confirm for sure that the 8700 in the Best Buy models is DDR2 would be Nvidia.

From a 3dmark06 standpoint it looks like the Best Buy cards (ddr2 8700?) scores similar to a dd3 8600.

 

The BB x205 is clocked no differently than any other x205, and scores no differently than it either. I'm 99.9% sure it's not DDR2.

 

plus....clock to clock, ddr2 and ddr3 perform about the same (ddr2 could actually be faster clock to clock because of the lower latency...), so I really don't understand the 3dmark06 argument...

 

The argument is that there's no way Toshiba manufactured that many units of DDR2 stable at 1400MHz, and even if they could do that the QA would be more expensive than just putting GDDR3 mem in there in the first place.

 

yea i know that what's i have been saying in the other thread too... it's might be possible if they volt-modded it plus some crazy memory cooling.

actually, I remember I had read an article some day ago saying that samsung had successfully produced some DDR2 memory which was capable to run@900Mhz(1800Mhz Effective)... but it did not go mass production probably because the cost was too high those must be the absolute best yield to go that high.

 

Related question...

Which computer would(in Theory) run better?

Toshiba X205-SLi1

or​

Toshiba X205-S9359

I'm curious whether one 8700M GT with 512MB is compareable to a computer that has 2 8600M GT with 256MB each, which when combined equal 512MB

Also does the game need to be programmed to use SLi? Or is it up to the drivers? Cause if the game isn't configured to use SLi then would it just use one of those cards?

i'm looking at buying one of those giving the fact the Compusa.com has the S9359 on sale for $2099

 

Its not DDR2 on that model... the results are too high to be DDR2 and nvidia does not even spec the 8700GT for DDR2.

The easiest explanation is the most likely one.
Typo.
Frankly, marketing people don't usually know the difference between GDDR2 and GDDR3.

 

We will not know which will run better for sure until the sli notebook systems are tested, but since you asked for a theoretical answer:

Based on the desktop world (the 8600 m gt is often compared to the desktop 8600 gt) sli made a larger difference in some games/programs than others. Oblivion and Prey are two games that were noted as showing noticeable improvements. (Games that are less demanding in the first place are less likely to show as much improvement).

Here is how Oblivion sli vs non-sli compared (based on pcper's tests) (the green bar represents a single 8600gt, and the purple bar represents a sli 8600gt cards) :


and here is how 3dmark, bf2142, and company of heroes tested:
(3dmark06 showed a 1,500 point increase in sli mode for whatever thats worth )
http://www.pcper.com/article.php?aid=399

Given that the 8600m has been viewed as weaker than its desktop counterpart we may see more of a performance boost than the desktop cards did.

Since there was never a desktop version of the 8700m it is difficult to factor in, but since many people have stated that the 8700 is (in their opinions nothing more than) a over clocked 8600. The dual 8600 system should out preform the 8700.

 

The desktop version is called the 8600GTS.

And yes, based on desktop performance results, dual 8600M-GT's should perform slightly better on average than a single 8700M-GT. In some games, like Prey at high quality and resolution, the single card should still be slightly faster, but in other games like Oblivion at high quality and resolution the dual cards should be nearly twice as fast as the single 8700M-GT.

 

thats why I added in Theory...

but what i got from that is in theory, yes it should...but it also depends on the game?

 

Yup, it depends on the game. For example, in desktop cards, when running Doom 3 at ultra quality on a UXGA screen, a single 8600GTS will manage 37fps, whereas 2 SLI'd 8600GT's will only manage 33fps. But in another game, like BF2142 at max and WUXGA, the SLI'd GT's will get 23fps but the GTS will only get 17fps. In general the two setup's are very close overall; in game's with good SLI support the 8600M-GT SLI will probably pull ahead by a decent margine, but in games with poor SLI support the 8700M-GT will probably be at least slightly faster. In Tom's Hardware reviews, across many games, resolutions, and settings, the 8600-GT SLI score 1188.7 and the 8600GTS scored 1127.5.

 

To me it looks like the desktop 8600 GT is closer to the 8700 than the desktop 8600 GTS (based on overall clocks - the shader and memory clocks are closer to the GT than GTS).

Dont forget to factor in 8700gt sli

 

The SLI 8700 GDDR3

 

True, but the comparison between desktop 8600GT and 8600GTS is essentially the same as the comparison between the 8600M-GT and the 8700M-GT.

 

shboyles has reported getting 6530 in 3dmark06 with the default drivers, default clocks, and 1280x1024 is SLI mode on his x205-sli ( dual 8600s).
(3700 in non-sli mode)
http://forum.notebookreview.com/showpost.php?p=2539133&postcount=18

Audigy had the following results on a 8700 at stock settings:
8700M GT do 4796 at 1280x1024 at stock(169.71 drivers)

KernalPanic reported 5194 3dmark06 at 1280x1024 (external monitor, stock drivers, 775/938x2 OC) for his 49 version of the x205
http://forum.notebookreview.com/showpost.php?p=2510414&postcount=12

shboyles should have more details for us on the x205 sli system in the next few days.

 

Well so we all agree that for the first time a gpu has more then about 40% performance increase because of 128bit bus !?!? 8700gt sli !!!! WIIIINS!!!

 

notebookcheck.com puts sli 8700m at 8000 on 3dmark06...is that true or have you heard otherwise?

 

That's about right based on M1730 results. Remeber the X205 SLI being referred to is dual 8600M-GT's, not 8700M's.

 

While the 3dmark06 scores are promising the results of game testing will be the real determining factor of how good the SLi system could be. (Plus for some people how the 8x00 sli systems effect battery life, heat, and weight of the systems may be as important as how much SLi may improve gaming).

 

oh yea, thanks for that...6500ish is pretty good no? thats on par with 7950gtx as single.

 

That fits with Justin from XoticPC reported 8103 in 3dmark06 on the Sager NP9261, Q6700, 2048 DDR2-800, 2x nV GF 8700M GT w/512MB SLi Driver version 156.55, 200GB 7200RPM SATA300, Windows Vista Ultimate x64

http://forum.notebookreview.com/show...8&postcount=46

 

so overall sli 8700m and sli 8600m are pretty good then i suppose. i mean scores above 6000+ on 3dmark06 usually mean that they should be able to play games quite nicely

 

According to the post at: http://forum.notebookreview.com/showpost.php?p=2522018&postcount=47
7950gtx gets 6492. Its been suggested that the the 8600sli scores may improve once bloatware is removed and the system is tweaked a bit. Of course 3dmark06 results mean nothing compared to game performance and quality.

 

If you want to know what they can do, look up Tom's Hardware reviews of the 8600GT SLI and the 8600GTS SLI. The mobile versions (8600M-GT and 8700M-GT) will be slower than those.

 

Then compare them to the 7950GT's to see how 3DMark06 overates the DX10 cards

 

ok i know this is a wee bit off topic but can anyone tell me a mobile gpu capable of play TES; Oblivion on max settings with everything turn on, smoothly?

 

At what resolution? At something like 1440x900, you'll need dual 7950GTX's to play smoothly at max quality (that's with no AA). At 1024x768 you'll come close with a single 8700M-GT, but something like an X1800XT or Go7950GTX would be better, and pretty much any of the SLI setups will handle that resolution.
