UPDATED - The Mobile Graphics Card Info Page - Most GPU Qs answered

just make sure to watch the temps.

I know a few people had to undervolt it since they coupled it up with a quad-core as well.

 

How much difference would you expect between these two of the same card? I'm having the DDR3 one, is it better than DDR2?

 

yes DDR 3 gpu would be better then a DDR2

 

In term of power and performance, which one better for a laptop?
ati hd 4870 (2x512mg=1gig) in crossfire or Nvidia GTX 280 1 gig?

thanks

 

The 4870 CF IIRC. You may check reviews though.

 

are you reffering to mobile cards or desktop cards? Im assuming laptop but just incase..

Desktop: GTX280 is better
Laptop: 4870

 

I prefer single card solution.

 

for desktop..
are they pretty equal ?

 

The GTX 280 is peforms well, and you can squeeze it into a 15.4". The CF 4870 is still limited to the rather large 18.4" Asus, but the performance is definitely better. By how much? Well get someone to benchmark against me in lets say, DMC4. If they want 1080p, I'll give them 1080p.

 

One high-end card vs two high-end cards. It's simple really.

 

Just so were clear her IS referring to desktop cards, and they CANNOT go into laptops.

 

id say dont bother putting 2 4870s in crossfire and go with a single 4870x2. or a dual 9800 gt's in sli.

 

In that case the 4870X2 is about the same as the GTX280. The 4870 CF should be slower than the 4870X2 because it will still be 1GB 256bits (while 4870X2 is 2GB 512bits).

For CF/SLI, memory doesn't add up. For dual core cards, it does (X2 for ATI, GX2 for Nvidia and the GTX 295)

 

I mean for laptop not desktop.

 

he means in a desktop, not a lappy

edit: no you are good, he just meant a lappy not a desktop lol

 

for a laptop the 4870's whip the 280

end of story thats the FACT

 

Laptop 4870x2 [crossfire] = better than a single gtx280m
desktop 4870x2 [single card] = also better than desktop gtx280

 

this is totally wrong.

dual-core cards split the memory between the 2 cores just like SLi/CF. also, the 4870x2 desktop card is considerably faster than a single gtx280 and gtx285, but just a tad slower than a gtx295.

 

Memory bus works in sync, hence why sli 256 bit cards are great for WUXGA. The framebuffer is different, and only the total for one card is used. So in the case of the 4870 x2, you've got 2x 256 bit memory bus but still only 512MB GDDR3. Extra framebuffer will only matter when you actually exceed that memory amount though. I suppose with the power of the 4870 x2, you'll be running 1080p and 4x AA frequently enough that 1GB would've have helped out.

 

And here ya go, OC'd 280M vs stock 4870 x2. Found the benches on page 70-72 on the W90 thread... good memory. No surprise the 4870 x2 wins, and it can still be overclocked (550/850 stock to 600/900, at least).

105.35 83.25 124.88 76.13 (97.40)

136.24 108.74 154.01 105.34 (126.08)

29.4% faster.. yeah it's one bench, but it gives a good idea how much faster. And remember, the W90 was stock, I wasn't. Thanks for the bench quad!

 

On the list 2x 4870s r better.

 

actually quadzilla has higher runs then that. i am not sure if he was stock or overclocked. but i the scores was so high i couldn't put my benchmarks up. Lol.

 

Are the people posting here cracked out?

On the desktop, a pair of 4870 512s will typically stomp the tar out of a GTX 280. I remember when the 4800 series came out, a pair of 4850s were better than the GTX 280, so I have a hard time believing a pair of 4870s would somehow perform worse. The ONLY times you'll really see the GTX 280 cream a pair of 512MB 4800s would be when the 512s start running out of memory, typically only at 2560x1600.

Also, correcting anothergeek, the HD 4870 X2 runs 2GB total of GDDR5. There are no 4870 X2s that run only 1GB total.

 

REDBALLZ!!!

 

he was refering to the ASUS w90p

 

If you're posting in a laptop site, I'm going to assume you're talking about laptops.... and guess what, the OP was

In the desktop world, the 295 rules the roost. End of story.

 

no...your cracked out for posting to a notebook site about notebook graphics cards....*LOL!*

which is better? ati hd 4870 (2x512mg=1gig) in crossfire or GTX 280 1 gig

================================================

and he didn't even edit it so there was no mistake there...lol

i think that crack had a reverse affect...lol

j/k

 

Mobility HD4870x2 is better than GTX280M single card by a rather large margin but at the very least 25% stronger.

On the desktop side, a 4870x2 indeed is still faster than a single GTX280 but the difference is not as big.

Hell, a pair of HD4770 in crossfire have almost the same performance as a single GTX285, and they only cost a total of 200dlrs!! (The GTX costs 340dlrs).

If we ever see a Mobility HD4860x2, that is what I am getting haha.

 

i second that

 

I thought he was some noob who didnt know that desktop cards dont go in laptops, ugh close this , a simple search would have answered this.

 

what up nars!
im about to put my i7 together later today i think.

 

Ok... let me put my 2.5 cents in.

Last I checked the Desktop GTX280 was not far ahead of a single 4870

But add a 2nd 4870 in crossfire and its no competition. The 4870 crossfire will win easy unless you find some really odd game that does not support crossfire.

The 4870X2 in the desktop is just ever so slightly faster than two 4870's in crossfire, and the added benifit of only needing one slot and no physical crossfire bridge. If you had a crossfire mobo you can still add yet another card in tandem with the 4870X2 for even more power (though it starts to scale less and less as you add more cards)


Now Notebooks, I own the Asus W90 with the 4870X2 in it, its actually two 4870's in crossfire and they call it a 4870X2, anyways all of the W90 owners benchmarks are beating the single GTX280M scores by a good margin, as to be expected, the GTX280M is just an overclocked 9800GTX and its a single card vs 2 cards.

If you want competition we need to wait for some GTX280M SLI scores, it may beat it, but also I assume will cost more.

 

sure is looking like an over clocked 9800m gtx....but with them extra 12 shaders, i think i could do some more damage..without over clocking my cpu/fsb.

 

i took on a 280m and beat in stock mode. but i don't want to be near it in sli. i am almost down in the gpu when you put to together.

 

best game to run all the cards against was far cry 2. they are all with in 4 frames of each other 59 to 62 ultra high sli/xfire. and the 3870's finally got a chance to shine here.

 

Hey while you're here, give us your overclocked 1080p DMC4 run, dondadah88


I'll need a QX9300 if I'm going to go against your FC2 runs though...

 

i am work right now so i can't but what setting do you want it at and i got you in 4 hours. i love benching dmc4

 

Just the usual, super high DX10 no AA and at 1920 x 1080. OC the 3870s high as you can go

 

Guys how is this new ATI 4530 512MB card? I didn't saw any benchmarks or any scores on this card. Any info on this card?

 

which is better 512MB DDR3 ATI Radeon HD 4650 mobile with 2GB's of DDR3 ram or 512MB NVIDIA 9600M GT with 4GB's of DDR2 ram? I'm planning on getting a laptop soon, and I'd like to get the best computer I can for under $1000, both computer's are the same price and other than gpu and ram are identical. (internally speaking). If it helps i'll be doing a lot of rendering.

 

sorry i took so long. i just reformated and installed dmc4. now installing overclocking driver and going to report back.

 

the last test i don't know what happened. the fps just dropped all the way down. my fps was fine and so was everything else.

 

OH YEAH!!!

 

All:

I've already used www.notebookcheck.com

I don't think they're all that reliable, though. Anybody have any real world experience as to how these cards fare against one another?

Thanks,

AV1611 out....

 

If they are both the same type of memory (GDDR2 or 3), the 4570 is better.

But if the 8600M GT is in GDDR3, it will probably beat the 4570 in GDDR2.
If the 4570 is in GDDR3, it just puts it u higher than the 8600 more.

But, anyway, id go with the 4570. The 8600M GT is defective, and can easily fail.

 

The 4570 is a 64 bit card, though. How does that figure into the mix? The notebooks I'm thinking about are 15.4" or 15.6" at 1440x900 or 1680x1050.

AV1611 out...

 

The 8600m GT is slightly better.

 

post the notebook that u are looking so we have a better idea

 

Dell XPS 1530
2.4 C2D 800Mhz 2MB cache
8600M GT 256MB DDR3
15.4" 1440x900

vs.

Dell Studio 15
2.4 C2D 800Mhz 2MB cache
HD4570 256MB DDR2 (I believe)
15.6" 1680x1050

 

Based on this ASUS review and my 8600M GT, I can tell you that the DDR2 8600M GT is 25-30% better than the DDR2 4570. The GDDR3 8600M GT will be even better than that, but there are fairly credible rumors about issues with the 8600M cards so make sure to get a decent warranty if you buy it.
