8700 vs. 7950

I woud like to see Real World Performance numbers....

I want to see if the numbers support what people are saying...

7950gtx go win... but its dx9

 

Where's your numbers?

Joe

 

steponz
if u are waiting for ur lappy with 2x8700's u might want to call xtopic
i was just told that they have NO 8700's and dont know when they R getting more
they thought yesterday but now MAYBE in 9 or 10 days from now

 

I just talked to them about the 8700's.. They should be in next week..

Post on the other thread...

I would like to see some performance stats... With the differences between these 2 cards....

Seems like alot of bs.... Lets see the numbers...

Joe

 

3dmark wont tell you much.

the 7950 is 256bit and will do way way better in sli in high res over 1440x900.

the 8700 will do great at low res and ok at high res. as bout as good as 1 7950 (no ****). there is real world benchmarks to prove it over at notebookforums.
check my sig FRAPS THREAD. read thru it it has dual 8700's vs 1 fx2500/ 7900gtx /7950.

 

lol, two 8700's clearly beat a 7950. I've tested it myself with my brother who has a single 7950 on his desktop.

Keep in mind that when I received my 9261 with 8700's it performed quite poorly... this was just 4 weeks ago. Performance soared when I changed to the 169.04 driver (which also came out within last 4 weeks).

Even if you just looks at the technical aspects, it's a joke to say a single 7950 beats two 8700's in SLI, lmao.

I'm not going to waste much time on this. My setup runs awesome, with maxed Oblivion at 1920x1200 hitting 60 FPS -- limited only by VSYNC.

EDIT: I just read your fraps post and there wasn't SH*T from anyone with 8700's in SLI. Just a bunch of 7950 slappies saying "7950 is soooo much better". lol.

 

yah, in sli, the disadvantage of the 8700 towards the 7950 is not a worry, because for the lack in performance you get dx10 effects AND run games at max, so.. in that case 8700's are the best choice.

 

I forgot to say I'm not even overclocking my 8700's right now.

There's no need -- they run awesome.

When games start taxing my graphics system, I'll OC then.

 

Kozi
did u just install the new driver or did u have to change the inf file then install?

 

just wait, the 8800m GTX was announced and will probably be release din notebooks very soon..this is what we have been waiting for

 

i think the release date it the 19th?

 

yea round then from what ive seen...yay!

 

Well, there is alot of fools that say what you said.

why don't you put your money where your mouth is and post some Benchmarks in there.

we had one person in there that posted his results.

we need more people.

so far all the people with 8700 in sli.

 

http://www.tomsguide.com/us/2007/10/15/sibling_rivalry/page9.html

Someone needs to put away his 7950GTX fanboi outfit.

Tom pretty neatly hits it on the head.

FEAR? Play it on the 7950GTX SLI, something is bugged as the 8700GT SLI setup is clipped at 80fps at all resolutions.
Oblivion? Play it on the 8700GT SLI
Doom3? Doesn't matter, they are both insanely overpowered for that game.


the 7950GTX's SLI massive performance difference? 15% in games, and most of that 1920x1200 and the buggy difference in FEAR.

Yes, 128-bit memory interfaces hurt for 1920x1200... big surprise.

All that said, a single 7950GTX has NO CHANCE against an SLI 8700GT unless we are talking FEAR which has some buggy and weird results.

(proof positive that any ONE benchmark -even a game- is not a true indication of anything other than that one game's performance.)

The 8700SLI performs quite well in games... and Tom even rates the SLI 8700 machine a better value once overclocked. (total price considered)

The 8700GT and even the SLI version has limitations... but let's not get rediculous.

 

what about 1x 7950gtx vs 1x 8700gt...?

 

in dx10, the 8700 is the only card supporting it, the 7950 is 25% faster in dx9.

 

I would like to see some benchmarks for real comparision. Which is what was asked for and the thread is about.

 

perfect so ill get this card and ill change it for a 8800gtx next year.

 

The comparison has been made before... and its not that simple.

The 8700GT performs MUCH closer to the 7950GTX in 1280x1024 and below (5-10%) and indeed can outperform it in some shader-intensive games. (yes even DX9)

Past 1280x1024, the margin starts increasing as the 8700Gt drowns itself with its 128-bit memory bus.

basically, the 8700GT is a comparable card until you get beyond 1280x1024.
(1440x900 is roughly the same amount of pixels)

If the point is which to get now, for once -yes stop the presses- I agree with Nars... wait for the 8800GT.

Given what the 8700GT can already do with HALF the memory bandwidth and 66% of the shader units, its a pretty good bet the 7950GTX will be pretty handily defeated by the 8800GT. (as expected)

Honestly, I'd love to see someone with both cards and a Clevo do a hands-on with all the updates and hotfixes and lastest drivers.

Any rich guys out there with time to burn?

 

thats what i did

it might be a while before u get an 8800

i could not wait

 

Not i I'm so broke i cant even pay attention

 

hahah u friggin hypocrite put away YOUR 8700m gt fanboi outfit

anyways im sick of this 8700 vs 7950 fight....theres a new card coming out that will crush both of them...it is similar to a desktop 8800gts so it should be a monster.

if you want directx 10 and use low resolutions go with the 8700, actually dont even consider the 8700, wait for the 8800gtx

and if you need WSXGA or WUXGA right at this minute then go with the 7950gtx

if you absolutly require

 

The 8700 does NOT have half the bandwidth of the 7950... u guys need to bone up on your terminology.

It has half the data width. On this simplest level bandwidth = data width * clock rate.

That puts the 7950 as follows:

550 mHz * 256 bits = 16.5 GB / sec

And the 8700 as follows:

800 mHz * 128 bits = 11.9 GB / sec

Clearly NOT half the bandwidth. Keep in mind these bandwidth calculations are simplistic and consider an ideal case with out the effects of collisions, etc.

Another nice thing about the 8700's is the overclocking ability. I can push my memory clock up to 1GHz which makes the bandwidth = 14.9 GB / sec (nearly the same as a stock 7950).

I've stated before that overclocking the memory doesn't produce the biggest gains in 3DMark06 -- the CPU clock provides more benefit! I'm not making that up, I speaking from my actual OC trials.

That tells me that the 8700 is not memory bandwidth limited by it's 128bit bus. If you feel that you have to have a 256 bit bus then wait for the 8800's -- keep in mind it doesn't have much of an impact on the 8700s.

 

actually it IS HALF THE BANDWIDTH

the 7950gtx puts out 44.8GB/S

the 8700gt puts out 24GB/S

not quite half, but almost.

and where did you get that 550mhz? if it was memory the 7950gtx's is rated at 700mhz.

 

Where are you quoting your 44 and 24 GB numbers? I've just explained how to calculate memory bandwidth.

There's no magic to it. If you're using pixel fill rates or some other metric, that's not the same. Those metrics are performance across the total system which includes memory, gpu, etc.

The 550 MHz I pulled off of a 7950 GT data sheet for XFX. I'm not sure what the Clevo 7950 clocks are exactly. Maybe you can provide that information from your own equipment.

I guarantee you the 8700 does not have half the memory bandwidth.

 

I hate doing this,, But this is from nvidia's website.

the 7950gtx puts out 44.8GB/S

the 8700gt puts out 24GB/S

darn now I feel like a tratior ...

 

last generation top videocard > new generation mid videocard

 

Maybe you are reading it different then me?

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

I know these aren't mobile cards but it shows the 8600 GT at 22.4 GB/s.

The 8600 GT has a 700MHz memory bus. The 8700M GT has an 800 MHz memory bus. You can see those clocks here:

http://www.nvidia.com/page/geforce8.html

Notice that it shows the 8600GTX at 1000 MHz memory clock with 32GB/s memory bandwidth. This is exactly what I can OC my 8700 to .

Regardless... what I said earlier holds true... bandwidth is a function of memory clock and data bus width. You have to consider both when talking about bandwidth. Simply stating that the 8700 has a 128-bit bus does NOT equate to half bandwidth.

If both the 8700 and 7950 have the same memory clock rate then it would. But the clocks on the 8700 are higher than the 7950.

Before all the 7950 slappies come out of the woodwork, note that I never said the 8700 had more memory bandwidth. I simply stated that 128-bit bus does not equate to half bandwidth.

 

Stop fighting and get a 8700 its 100$ less than the 7950

 

Thats what I did and figured I would have the extra 100$ next year when I want to upgrade. As for which is better the 7950 is a faster card, no argument. But for DX10 now in a laptop and still keep the res up and the eye candy on and keeping the price down the 8700 wins. It depneds on what you want.
