GTX460M vs ati 5870m

is there going to be a huge difference in performance? what differences will be noticed in FPS etc.... since its confirmed the new g73 and g53 will both have it.

is the gtx 460 worth the wait??? or will there be a slight difference and better off getting a g73 now?

 

The 460M is slower. How much is unknown, until benchmarks surface.

 

so the new g73 refresh, will actually be a downgrade? from the current ati 5870?

 

The 5870 is on par with the gtx 480m in everything except heavy tesselation (where even the 480m doesnt provide a playable fps so not really a usable advantage), so the gtx 460m should be weaker yes.

 

Agree with the info above, the GTX460m will be less in performance. It would still have the DX11 support and should hopefully be more stable than the ATI HD5870 (PSOD issues), but with better driver support beings it's nVidia based.

The G73 refresh more than likely won't come out until Q4 though

 

I'm interested in how the 460 will perform with Adobe products.

 

I didn't expect the GTX480 in the new G73 given the heat and power but the GTX470 would have been a nice alternative.

GTX460 should be more on par with an ATI 5850 than a ATi5870 so I really won't have any regrets on buying a G73JH so late in the game

 

Same here, all aboard the 73JH train Personally I don't think it will be any more stable than ATI's current 5x series, and the initial driver support will be poor, though nv catches up quickly there.

It will be interesting to see how much heat the 460 puts out - less than the 480 for sure, more than the 5870?

 

I suppose the big difference will be Physx support.

 

I think we have more threads on this now w/ benchmarks but I cant find them with search.

I have always thought the 5870m will be better but I do recall (I think Alienware forums section) that the GTX460M was actually keeping up really well.

Im thinking about getting the new 3D G73 and since it only has the GTX460M option I would like to know what kind of performance loss to expect moving away from my JH model with the 5870M.

I think that both cards are not really strong enough for 3d gaming on high settings, shame. The should have pushed for the GTX480 in the new model that would have helped some.

 

Unless they left the GTX460M as an option they lose a lot of sales with that ~$700 price increase. The 120hz screens also tend to be low resolutions if I'm not mistaken, and if that's the case high details should be viable.

1366x768x2 (2 representing double the frames needed) = 2,098,176

1920x1080 = 2,073,600

3D at 1366x768 is negligibly more difficult than non-3D on a 1080p screen.

 

Doesn't a 800/1100 (~10%) overclock on the 5870m bench roughly equal to a 480m? I actually wish that 5870m could be down-volted more; dare I say it...the 5870 is overkill....

Run dxdiag; what's up with the "Approx Total Memory" of 4gb? If I run, say, 16x AA across 4 displays (I know this is not physically possible.... just theoretically) and exceed the 1gb gddr5, it'll start pulling from ddr3 system memory? Wouldn't that be slow as molasses?

 

The new G73 is still 1920x1080 your thinking of the 15" model with the lower res screen.

Id never go below 1920x1200 or 1920x1080 I need those pixels for lots of things

 

The MR5870 can be undervolted. I have mine running at 1.05v instead of 1.15v (at the stock clocks of 700/1000). I did it by getting the vbios off the card with WinFlash, modifying them with RBE, and reflashing in a DOS environment.

 

You guys forget the 1,5GB (460M) vs 1GB (5870) difference which should be significant in intensive high resolution-high AA scenes.

 

It's not. Nope. It's not significant at all. At 1080p, difference between 4X MSAA and 8MSAA is only about 100mb, sometimes none at all.

It wasn't even Nvidia that started shipping with 1GB of ram, it was the AIB who did it, to get an edge on marketing their products. To date, there isn't any significant evidence that you even need more than 512mb for gaming. Professional work may be a different story.







Here are benchmarks of how much ram is used. As can see, having more than 1GB is excess ram. No matter what Nvidia's AIB partners want to convince you otherwise. Quantity of ram has no direct impact on performance. Having 1.5gb will not increase performance, it's just excess ram. The only time ram is an issue is if you don't have enough of it. Bandwidth and speed is what matters.

The major flaw with these benchmarks is that there is no comparison of 1.5GB vs 1GB to see if it has any impact. My assumption would be no.

Fascinating info Ruckus, thank you. Now I know why my friend was so happy to buy his desktop GTX460 768mb for $115 new. I thought it was fools bargain because it didn't have 1gb of memory, but looks he doesn't need it anyway.

 

Aren't those the old architecture? Or does it matter?

 

Some are 4870, Some GTX 470 and some 8800. I'd say they are new architectures. I am not the only one who thinks the 8800-GF110 are pretty much the same. The HD4xxx to HD6xxx are similar also.

Not to say video ram isn't needed, but not to the extent for gaming as some marketing would suggest. Anything from 512mb to 1GB should be fine.

 

vRam is important for anything that keeps tonnes of textures in memory. Since the bus speed is generally sufficient to move stuff around as needed - and really, 500meg of textures - imagine how big that is...

 

Howdy!

I've been lurking for quite some time, so this will be my first post. I am in a tough position right now in regards to choosing between the two G73 lines. I have been doing much research on the G73jh-bst7 with its 5870 ATI card. Up until yesterday, I started reading up on the G73jw series which included nVidia's 460m card. Price range between each series (aside from the 3D version) are practically similar. I do know the JW series offer a few upgraded parts, however, I am not too concerned of it.

Getting on point, in terms of the graphics cards -- how practical is it that the 460m will increase in performance with updated drivers? I mean, are we able to say that the 460m will be as performing, or even better, than the 5870 for the time to come?

 

Nope. Sure, nvidia can improve drivers, but so can ATI. And the cards are ~10% different in terms of power and there is no way nvidia can squeeze another 10% with drivers.

 

I wonder how that card scales with overclocking...? Vs ours?

 

the difference is ~4% as per notebookcheck..which the drivers might help as nvidia has bettr driver supprt i heard
