280m sli or HD 5870 mobility

[Option]

Topic.

 

[deadlockedworld]

Since you can't upgrade laptops I think it would be important to consider the rest of the system.. Maybe you should post your options in detail.

 

[wa1]

Agree, post the detail both of the laptops here...

 

[sayantan]

I would vote for 5870 mobility,as it would consume less power and perform almost the same as 280m in sli...also you get the dx11 support

 

[Maziar]

No,HD 5870 mobility will perform like a desktop HD 5750 and a GTX 280M performs like a desktop 9800GTX,so 2 GTX 280M would be a faster option,however it depends on the other specs and the games and the resolution that you play

how can you say no !!one nvidia 280m gives 624Mflops while one 5870 mobility gives 1.12Tflops. So two 280M sli is almost same as one 5870 mobility...

Raw computing power does not directly correlate with performance. In the second page you linked, it says:
"Compared to desktop graphics cards, the Mobility Radeon HD 5870 should perform somewhere between a Radeon HD 5750 and 5770 according to the specs (shader count of 5770, clock rate of 5750)."

And on the page for the 280M:
"Compared with Desktop graphic cards, the performance is about between the 9800 GT and the 9800 GTX (which has a considerably higher clock of 675/1675/1100)."
http://www.notebookcheck.net/NVIDIA-GeForce-GTX-280M.14558.0.html

Consulting the charts on a 9800GT/GTX SLI compared to a 5750 gives a rough idea of performance:

Maziar is correct in that the 280M SLI is the stronger option, and also correct in that it depends some on usage of the cards.

wonder if there will be a 5970 mobility

how can the real life benchmark differ so much even though they have almost same raw computing power!!!

Wait for benchmarks.

Yes agree. The 5870m performance is around 5750 or 5770 desktop version. gtx280m sli will beat it easily. 5870m isnt a bad option uses less power, run cooler, supports dx11, oc a bit higher and will probably cost you a less money. But for pure performance gtx280m sli.

 

[Maziar]

Its really easy to compare,a HD 5870M performs between a desktop 5750 and a 5770 and a GTX 280M performs like a desktop 9800GTX,and 2 9800GTX perform better than both HD 5750/5770 so 2 GTX 280M perform better than 1 HD 5870M.
Wait for real benchmarks and we can have the exact answer.

 

[wa1]

but still, for a laptop, it's powerful enough(both of 280m sli and HD 5870 mobility) ...

 

[miha2]

so, just answer if mobility 5870 worth of it. i'm planning to get a laptop soon, so i need to know if i should take asus' g73... or some other with gtx 280m sli. i don't want to take sli'ed, since the heat will be huge. so i want to know if it'll be ok to play on it. i'm planning to play dirt 2 on it, so what resolution should i play on?

 

[Maziar]

If you aren't going to SLI then HD 5870M performs better than 1 GTX 280M and can handle Dirt2 fine

 

[miha2]

"HD 5870M performs better than 1 GTX 280M and can handle Dirt2 fine"
how fine? at 1920x1080 with aa x4, af x8? of course with i7 720

 

[Maziar]

No,HD 5780M performs better than a single GTX 280M.

It can handle it fine with some settings on high and some on medium and with 0xAA,but since it isn't out yet we cant' give you 100% accurate answers but it performs between a desktop HD 5750 and HD 5770

 

[miha2]

i know that 280m sli is better, but, from the other side, in crysis, 5870 is ~45-52 fps, 280m ~45, 280m SLI ~47. however, i don't know what's wrong, but 260m gives ~52 fps. but again, i want to see DX11 in action in DiRT2. and i want the laptop to handle on my laps, not on the table - i don't want it to be 212F hot. i don't want it as noisy as a plane in a couple of feet from me, but i want it cool, quiet and good. of course, they're not going to be that noisy and hot, but anyway, i want it cool and quet. so, i just need the benchmarks to see how good it can perform in just 2 games at 1680x1050 (since it'll be the closest to 1920x1080) or at 1920x1080, no aa+af. and the games are crysis and dirt 2. if it can run crysis on native resolution, it can run any game. if it can run dirt 2 in dx11, it can run any game in dx10/9. right?

 

[AMW1011]

The 5870 is extremely close to dual GTX 280m, but it uses less than half the power, 60w vs 150w, meaning the 5870 will net you far better battery life and can be fit in smaller form factors.

[Maziar]

No it's not close.
HD 5870M performs between a desktop HD 5750 and 5770 and a GTX 280M performs like a desktop 9800GTX so in SLI it will be like 2 9800GTX's and they perform better than a single HD 5870M

Where are you getting those numbers ?
As i said real benchies aren't out yet so why not wait a little more for real benchmarks ?

 

[miha2]

ok, ok. don't get angry. but well, they'll most probably again will say that it'll come in February or later.

 

[Maziar]

lol i didn't get angry i just wanted to know where did you get those benchies,why i must get angry lol

HD 5870M performs between a desktop HD 5750 and 5770 and a GTX 280M performs like a desktop 9800GTX so in SLI it will be like 2 9800GTX's and they perform better than a single HD 5870M

The GTX 280m is based off of the G92b architecture, the same as the 9800 GTX, but has far inferior clocks and memory speeds. It is a between the 9600 GT and the 9800 GT in performance. Two of them with the inferior mobile SLI scaling are going to come pretty close to the 5770.

The performance difference is not worth the extra power consumption, 60w vs 150w.
