**official** 7950gtx Vs 8700gt

More specifically, the memory clock speed would have to be double that of the 7950GTX. I.E. you'd have to overclock the memory on the 8700M-GT to 1400Mhz (2800MHz effective), which is practically speaking impossible. However, that kind of an overclock would give the 8700M-GT equal memory bandwith with much greater shading power and fill-rates then the 7950GTX. In actuality, to make the two cards equal, you'd have to significantly downclock the shader domain and the ROP domain of the 8700M-GT, and overclock the memory to the aforementioned speeds.

 

Yes(at lower ressolutions like 1280x1024).

An 8700M GT, at stock frequencies of 625Mhz core e 800Mhz mem, can do something around 4700/5100 marks on 3DMark06(at 1280x1024). An 7950GTX can do something around 5500 on the same conditions.

The 8700M GT can support an huge amount of overclock, something around 800Mhz on core and 1000Mhz on mem. With that OC, you will improve the performance on 20/30%, and that will overpass the 7950GTX at 1280x1024. The 7950GTX with the 256bits bus, will be a little better on very high ressolutions.

Just to mention that my 8700M GT never gets more than 60ºC on full load, even after some hours playing Bioshock DX10 or CMDiRT. The 7950GTX on the other hand, will have temperatures near 90ºC wich is a lot.

The 8700M GT have a lot of potential, we only need to unleash it

 

I benchmarked my system with a stock m1730 at high res (native) and I went head to head with scores fraps on oblivion and bioshock.

 

high res is what it's all about. i mean the high end lappy's have 1900x1200+ dislpays

 

New 167.26 drivers for 8700m GT jump 1000 points on 3dmarks06!
Now single stock 8700m GT already average 5500 and run as cool!!

Now evidently 8700m GT is jumping ahead of 7950GTX with new better DX10 driver,
and not looking back...

Now where did the 1000 points come from?!!?
It can't be because it suddenly has more memory bandwidth I supposed...
looks like the other dx10 parts of 8700m is starting to play up its magic...and memory issue is less significant now.

Can't imagine the lead of a 8700m GT SLi....

 

of course, that's just in a benchmark
what that gives in FPS, remains to be tested
any takers?

 

and what happen to 7950 gtx in that drivers ?

and what happen to 256bit bus ?

 

7950 go gtx is out for sometime...the drivers has mostly matured for it...
The most upside in the driver will come for new 8700m with the new dx10 architecture like unified shaders, parallel pipelines, etc..playing a bigger contribution now.
The memory bus is less significant now due to better data flow/conflict management by the new driver....thus the mem limitation issue is less of an issue with the new drivers...
It's a 1000 jump not 100 something in the driver must have changed significantly in favour of 8700m dx10 architecture; and minimizing the effect of the memory limitation.

 

As I said before: we don't know yet how it changed. Maybe the changes primeraly reflects the benchmark. If it doesn't do much for games, it's pretty useless, except as sales arguement for nVidia.

 

Wow its still incredible how a piece of software can change all that. I was seriously worried about my two 8700m GT's in SLI in my 1730, because all around I was reading and hearing about it not being better in games than the 7950 GTX. But maybe it will be now. Especially after I OC them! :d

 

Is the Xps Dell 1730 real good
any complains ?

 

Kaput

What do you say about this?

On my 8700M GT, 775Mhz@Core 1000@Mem artifact free, 167.26 drivers

3DMark06 at 1280x1024:

 

I havn't recieved it yet. I'll let you know what I think when I get it. People are mostly really happy about theirs. There have been some complaints about the screen, because people in Australia get a Samsung screen which apparently has some light leaking. But know with this knew driver, the XPS m1730 just became even more powerful!

 

Yet still no driver will make the 8700GT perform any good at higher resolutions wth AA and AF enabled.

 

So for High resolutions
guess we need to wait for the 8800 cards

 

How do you know?

 

Can we get some higher-res benchmarks? I still have time to switch to the 87000GT in the M570RU order I placed last night...

 

look at the bench in the review, there are high res's, and obv we would know the 8700 will perform poorly at that res.

 

Those benchmarks aren't with the 167.26 drivers that everyone's been freaking out about.

 

drivers are not going to make this card magically perform better. its got nothing to do with drivers why it performs this way.

 

Still like narsnail said the card is indeed crippled by its 128 bit bus.

 

I too would love to see some higher rez scores on the 8700gt with the new drivers, the 128 bit bus should still limit it, low rez does not prove much. I also have an order in for D901C with a 7950gtx. Please run us some higher rez scores as per the original review. Thanks!

 

then please do tell where the performance increase comes from, if not from the driver

 

No need to be so dismissive of a valuable question. I'm inclined to agree with you but I'd like to see the numbers to back it up. It's always better that way.

 

First of all, we've seen no clear performance increase with the new drivers (I haven't at least). Only a 3dmark06 increase, which means little or nothing. Second of all, these 3dmark06 increases we've seen are at 1280x1024, and no one's claiming that the 8700M-GT isn't a great card at that kind of resolution. Please either provide some 3dmark06 comparisons between the 167 and older drivers at 1600x1200 or 1920x1200, or better yet, provide some actual high res gaming benchmarks.

 

well i did write the review, and there is no way that drivers will improve high res gaming on this card, based on the internals of the card. its mid range and not meant for high resolutions and the only reason it is being put in high end gaming machines is because it is the highest available right now for DX10

 

I don't get how you got 6000+ on your 3d mark. I have a 2.8 core 2 extreme and am using the same drivers and I'm only getting around 4946 on my score. This score is with SLI on. Anyone have any ideas what I'm not doing right? Thanks.

 

Look at the attached Excel (3Dmark exported to excel).
Notice the perfomance increase with the 167.26 compared to the 163.74 (the percentage is for the 1920x1200 resolution)

HOWEVER, also note that, strangly, the internal clocked seems to be decreased by 38% for the 1920x1200. I've never overclocked this card, so I have no idea what caused this!

Seems I can't add .xls, so I'll put it in a zip
Means you foks will have a bit more work

 

My bad. I installed the new drivers and it turned off my sli. That score is with SLI off. It's still pretty low compared to the 6000+ mark score on your single card.

 

I will have to investigate the new drivers over the weekend...

 

Well, I can't get 3dmark to work now with sli on, so I'm going to reinstall it, but I have to say that the new drivers are absolutely amazing. GRAW2 now works at 1920 res and it's playing very smoothly - medium textures of course, but even on high it's now playable, which was impossible before.

 

How do you know it's not from the driver??
This is so misleading, coming from someone who does not even owns a 8700m GT.
All the rest of us owning a 8700m GT are seeing performance increase using the new driver!
Now I can play WIC smoothly at high settings in 1680x1024

 

just to be clear: I'm not the one who claims a score of 6000
my comparison shows 4877 in 1280x1024 and 3535 in 1920x1200, with the new drivers

 

World in Conflict smoothly at that rez, tell me what settings you are using, since maxed DX10 on my 8800GTX the game doesn´t "Always" run smoothly if there´s lots lots of action on screen at once.

So instead of writing smoothly, provide a screenshot of what fps you´re getting.

 

I set it at the default "high" settings, one notch above "medium".
Yap if there is a lot of actions on screen, the cpu is maxed out before the gpu....

 

because drivers cant change the internals of a card and the bus width is always going to hold it back.

I dont disagree that would see better performance with newer drivers, but its not going to turn into a 7950gtx for god sake.

 

Hiya.. we are talking about driver pushing up massive performance for 8700m GT
- from 4500 3dmarks06 to 5500 stock, and 6150+ overclocked.

Internals-wise, 8700m GT is definitely not the same as 7950go GTX,
it's has a DX10 internal unified/parallel pipeline architecture!!

 

Actually narsnail, driver updates could indeed potentially minimize the limitation of the 128bit bus width. I don't believe that's what's happening here, however it is possible.

 

read my post a few pages back, which contains the 3Dmark score
this is NOT true, you get about 100 points more, NOT 1000

 

Confirmed...my score only changed by about 10 points in both benchmarks (05 and 06). If anything, they are more unstable for me. My external monitor does not always play happy with them, and UT3 crashes every time I try to start it (not sure if it is the game or the drivers...). I'm downgrading back to my trusty previous version of my driver soon...

 

How can a software driver minimize the limitation of the 128bit bus. Seems like people here still thinks a software driver will do miracles to it´s already crippled bus.

Now didn´t the 8700GT perform really bad in higher resolutions, so I would like to know what kind of FPS the guy with World in Conflict gets at 1680x1050 with his 8700GT. Smoothly for me is 30+.

 

If you're referring to my post, then please not that I said I do not think it's the case here, I do not believe we'll see a miracle driver for the 8700M-GT (not with current game engines at least). However, it is theoretically possible for a driver to minimize the buswidth limitation, by optimizing performance for a small texture + heavy shading type situation. Hopefully, as the new DX10 style API matures (along with engines and drivers), we'll see games take advantage of the massive processing power of the 8700M-GT, without relying on huge textures as has previously been the case.

 

3d mark 06 - The fraud

 

yeap 3dmarks06 is "flawed".
Tis guy break the 6150 mark!
http://forum.notebookreview.com/showthread.php?p=2602112#post2602112

 

Half of this forum seems dominated by the 3dmark06 fetish! Being a common benchmark and all it's one way of doing comparisons but not everyone is going to see magic performance from the same driver.

 

Here is the proof that Dual Rank Memory Bus used on the 8700M GT really helps...

3DMark06 1680x1050(max on my LCD)
Same clocks as the 6000 score on 1280x1024 -> 776 Core/1000 Mem totally artifact free.



xenupy can you do me an 3DMark06 run on your 7950GTX at 1680x1050? Just to compare, and see how much the 8700M GT loses at that ressolution... Thanks

 

im sorry but 3dmark means nothing...the real world performance does not correlate with that score

 

well its official!!

167.26 drivers + 8700m gt overclocked > 7950gtx overclocked

 

Only at low resolutions...

 

No one has tested it on high resolutions yet with the new drivers and the overclocking.
