Questions about GTX 660 and AMD 7850!

post #1 of 40
Thread Starter 
Hi,

Lets consider the following to be true :

"The most likely configuration for the ‘660 is considered six ‘SMX’ clusters implying 1152 ‘CUDA cores’. Given the purported 1.5GB of RAM, this would typically a 192-bit memory bus (given the way these things usually work). There are also some suggestions that the card (which from the rear-shot is unsurprisingly a dual-slot one) could be artificially delayed due to a backlog of GTX 570s.

Given the GTX 660's potential to shake up the all-important mid market currently held by the AMD HD 7870 and 7850, Atomic will make sure to keep you informed of further developments."
(Source: http://www.atomicmpc.com.au/News/304414,acer-accidentally-kind-of-announces-gtx-660.aspx)

When it comes to 1920x1080 Full HD resolution, would the 1.5GB of v.ram be a problem if you want to play on Ultra settings? Lets say games such as BF3, Skryim, D3?

Which card will be the more powerful card? the 7850 or the 660?

Thanks in advance!

It doesn't make such a big difference between 1.5gb and 2gb. More VRAM is better for Full hd screens but doesn't make any diff if it's on ultra or not. It would be perfectly playable with 1.5 gb on ultra.

1,5GB will be enough for most game's.

I mostly see a usage of around 800 to 1200MB on the game's i play.

Skyrim will need alot more if you run texture mods.
BF3 also eats up memory.

Skyrim can even use more then the 2GB of a 7850 when modded.

What card wil perform better ? nobody knows, i expect it to be the GTX660 though.

Overclocked a 7850 is very fast for the price you pay.

What one to get ?
If you can wait, wait it out.
Nobody knows the exact performance of a GTX660 yet frown.gif

If I understand correctly "modding" is using software that is not in the "original" game settings to improve graphics, right? I am not interested in that, I am only interested in playing the game on max settings within the games original settings.

For this, is 1.5GB enough?

I am going to wait it out, just curious about the v.ram and ultra settings on 1920x1080 full HD.

unmodded Skyrim will be fine with 1.5GB of Vram.

But why run Skyrim unmodded ? it really looks so much better with mods.

And yes, these mods is just "software" that is not original to the game.
It enhances texture's, shadows, lighting and so on by replacing the original file with a new one.
Have a look here wink.gif

GTX 660 will be faster than the HD 7850. Against the HD 7870 my guess is GTX 660 will be faster at resolutions upto 1080p/1200p. The higher resolutions of 1440P and 1600p might be more difficult for GTX 660 because it will be fill rate consrained with just 24 ROPs and the HD 7870 with 32 ROPs might have the edge.

GTX 660 specs are expected to be 3 GPC, 6 SMX, 1152 cores, 24 ROP, 1.5 GB GDDR5, 144GB/s. The expected price for GTX 660 is USD 300. at those prices it will compete with HD 7870.

http://videocardz.com/nvidia/geforce-600/geforce-gtx-660

GTX 660 will be faster than HD 7870 as long as its not pixel fill rate constrained. the lower resolutions won't be demanding on fill rate. so GTX 660 will be faster than HD 7870 and maybe even GTX 580 upto 1680 x 1050 and maybe even 1080p. starting from 1200p and then going up to 1440p and 1600p GTX 660 will be hampered by fill rate limitations and fall behind the other 2 cards.
