ATI Mobility Radeon HD 4870 X2 w/GDDR5

Either my googling skills suck or there isn't very much information on Mobility 4870x2 w/GDDR5. What websites do you guys visit to check up on news about new GPUs for laptops?

Asus has the 4870s but with GDDR3, no one has them with GDDR5. Can we expect these to be released anytime soon? if so who do you think will likely be the first one to release these in their notebooks?

Also what would you pick? 280m GTX w/GDDR3 Sli or 4870x2 w/GDDR5. (Based on performance not price, 4870s will probably be cheaper than 280ms)

 

The only laptop that I know may get them is the Dellienware M17X

I think currently the GDDR3 4870's are beating the GTX280's thats what somebody told me but I need to verify.

My 3dmark09 Vantage score with 2.8ghz Q9000 and 4870X2 GDDR3 is just short of P11,000

Gpu score is just over 11,000 and thats what you need to compare.

 

yea that would be a cook-out, my desktop card has fan on 30% and idles at 55c, and that is with a dual slot cooler with the fastest and loudest fan i have ever seen.

 

I'd pick the 280's simply because they actually exist.

The very first gaming laptops with the 280's in SLI is the Alienware M17x.

Just now, the folks are starting to receive them from A.W.

Wait a couple days and you'll start to see the benchmarks and FPS while gaming. After that, the tweaking will begin and you'll start to see improvements.

4870's w/GDDR5 so far are nothing more than speculation, so if they do come out, who knows.

Proof in testing in the real world is always way more accurate than an educated guess.

The only testing I saw of 280's in SLI shows benchmarks like Vantage about on par with the current 4870's w/DDR3 however the actual FPS during gaming at higher resolution is better.

 

Until know, the GTX 280M is better than the 4870 X2 with the GDDR3, but the GDDR5 will most likely to give the 4870's a huge in performance and making it back at the top again.
But you never know what would happen, and you also might wanna take in considerations the drivers that are being used, as if they could get like an "optimized" driver for a card, it would actually might give it a leap in performance as well.

So until the you have real testing, just like Rob said, you can't really guess....

 

Yes, this is the truth.

 

i love ati alot more then nvidia but when i read
http://news.softpedia.com/news/Micron-Unveils-New-Low-Power-DDR3-Notebook-Memory-114577.shtml

i am happy that i went to nvidia

 

Where does that show? I need some proof.

 

well the 280 stock got 15707 on 3dmark06 with a [email protected] and 9??? in vantage on the gpu score. stock manchine.

 

Good you point it out, it was done with a Quad-core.
Check this out for a better comparison.

You mean they're beating Sli 9800M GTX by a small amount. John isn't some benchmarking god, his numbers are achievable by anyone.

What we do know is that 9800M GTX, 260M, 280M, 4850, 4870 are all within 10% of each other. So what are we making a big deal about here?

 

So... Let me see...

9800gtx has similar performance to 8800gtx
9800gtx is close to 4870 peformance
That makes my 3870 close to... erm, 7950gtx at best! which scores 5k 3dmark (instead of 8k-9k 3870's score, single GPU's ofc) yey....

Wondering how many people know what they are actually talking about

 

john's scores isnt's easy to beat.

but we want the best. i'm stopping at the 9800m gtx sli for now. i can really push these cards and at stock with a single card, i can max out any game at 1920*1200(alittle above 30fps in most games.) and that's at 500/1250/800.

i just know the 280m sli overclocked is about 80-90 percent faster then the 3870 crossfired.(the 3870's crossfired isn't a toy btw)

and i think the 4870's is a about 60-70 percent more stock.


this is in vantage gpu score.

3870 crossfired 6200 stock(me)
4870 crossfired 10,000 stock(stock drivers is 9600)(vic)
280m sli 9900(stock drivers unoptimzed)(vandit)
9800m sli 9??? (stock)(johnksss)
3870 ?????(???)
4870 ????? (i have to look in the msi thread)
280????(i don't know stock)
9800 5200(me hehe)
we need a central place for these scores. i know many people tried but.

 

This could be the Mobility 4870 GDDR5 pictured in the Alienware M17x:




Note the line - VGA/B: PWA VGA/B AMD M98 Q GD5 1G AB330 G

AMD M98 is the ATI 4800 series GPU

Q GD5 1G could represent GDDR5 1Gig...with Q standing for Qimonda the RAM manufacturer of the system RAM and also the brand of VRAM ATI used on the original Mobility 4800 reference cards.

PWA stands for Printed Wiring Assembly (a.k.a. PCB) and A330 G I believe is the motherboard model.

Source article says it's a single 4850 with 1G of RAM. If that VRAM turns out to be GDDR5 Alienware would have done the reverse of what ASUS did with the W90's 4870.

 

well technically that DDR5 4850 would have a 256 bit bus and UBER memory bandwidth...

up the clocks and you have the 4870 "true"

 

This is the first time I've seen the silver M17x closed and opened 3/4 sideways, and it looks amazing. Now about the ATi cards, could be that they'll offer both the 4850 and 4870s as well. And W850Di? Even if it's labeled as such I can't see Arima/Flextronics making something like this. Looks more like a Quanta custom job. But I could be wrong. Maybe Zfactor could help us out on this seeing as he seems to have a lot of contacts in the notebook ODM underground.

 

Yeah Zfactor's already looked into it. Got a thread going in the AW forums too.

 

Flextronics is the ODM of the M17x

thats why its M17x

m15x , m17x = quanta
M17 M17x == Flex

Flex is just saying ask Dell and laughing @ Zfactor when he calls

quite good news and exlains why they dumped the M17 so that they could design this

looks liek they stole Quanta designs

 

Do the systems using the 4870 X2 fully utilize the GDDR5 efficiently given that it has slower core clock than the desktop version of the 4870 X2? I'm just amused with its feature of a GDDR5 graphics memory, while other cards are in GDDR3.

 

Yeah i must say, gddr5 is a big leap.

And howcome 3850 cross is like 6000 is vantage, i thought i saw someone with a 14-16k record for that thing

Or are we talking stock in general?

 

you're confusing vantage (6k) and 3dmark06 (16k)

 

Oops, sorry geek, your right, what i meant is, shouldnt 14-16 06 be hitting more in vantage?

6k seems awefully low dont you think, especially for something that can hit quite high in 3dmark 06.

 

you mean the 3870's.
stock is 6000 @650/850. mild overclock 6400 @700/900 heavily overclocked 7000 @???/???. and extremed (e-wrecked)9000 @???/???.
