Which card is more powerfull?
GeForce GTX 560M 3GB or GeForce GTX 485M 2GB?
This is a great site for laptop GPUs:
+1, been pimping notebookcheck for years now.
From basic gpu history, you can generally compare the newer series to the older series by a 10% improvement. So, take the 460m and add 10% to it and you roughly have a 560m.
Looks like the 485M is going to trump it (more shaders & more memory bandwidth). The size of the memory isn't going to affect anything unless it's under 1GB.
Those site hasn't got GTX 560M with 3GB
The extra memory doesn't make a difference unless it's less than what the card normally comes with. Unless you're going to be hooking it up to a 30" monitor, then it might make a 5% difference.
Yes it does:
485M is 14% faster on average.
lol. It has got 1,5 GB, not a 3GB
Nicklan, that does not make a noticable difference in performance.
Take the GTX 580. The difference between 3GB and 1.5GB is 3%. Not significant!
Especially on a laptop that most likely uses a lower monitor resolution. If anything the extra ram does nothing but eat into battery life. What a waste!
Extra RAM on GPUs is strictly for marketing purposes, unless you're doing a multi-monitor, multi-card setup. That one of the few times where extra GPU RAM actually helps.
Some companies actually go from high performance RAM to twice the RAM, but a much lower performance RAM, and it can severely hamper performance, while the uneducated customer thinks it's better, and pays more money for it.
Wrong wrong wong
There are differences between the 1.5 and 3gb 560m. The 1.5 gb 560m video card that you see is most laptops uses 128 bit memory interface while the 3gb version (Asus g74sx for example) uses a 192 bit interface. Bigger tube better performance.
Note: I read the warning that this post was old but considering it was one of the top posts in my search I feel it still warrants correction.
Nope. However more lube means more performance for sure.
That's a fairly unique occurrence, but definitely one of note. I wouldn't call that "wrong wrong wrong" though.
Most cards with the same GPU side by side will perform nearly equally with different amount of RAM unless you're at a high resolution. Some manufacturers will actually sell two variants of a mid-range card. One with 1GB of GDDR5, and one with 2GB of GDDR3. The former performs a lot faster while the 2GB card lags behind, therefore tricking the uninformed consumer into purchasing the inferior card.
Regarding your first paragraph, it is definitely an occurrence of note considering the original post was regarding the 560m 3gb which allows me to say the information that everybody was giving the OP was wrong because it is not in fact the same as the 1.5gb version.
Regarding your second paragraph, what you said is 100% accurate and I myself have fallen victim to this market scheme before.. very annoying!
Just noticed the multi-quote but too late now. The Best Buy 560m is only 128 bit. Seems the vast majority of them are 192 bit but another lesson I have learned previously, do not buy best buy
Worst buy is the crappiest place to buy anything. They overcharge for everything, and they water their products down to make more money selling them to uneducated consumers. Anyone with a handful of self respect should avoid that place completely. There's no reason to shop there IMO. Not that any of this is related to the topic, but this thread is so old it doesn't really matter anymore lol.
Separate names with a comma.
