How can 1GB (560Ti) of graphical memory be on par with 2GB (6950)?

post #1 of 23
Thread Starter 
What does the memory size of a GPU means? We all know 560Ti's carry 1GB of video memory (while some carry 2GB), and 6950's carry 2GB of video memory.

Now for the regular user who buys a new PC and has to choose between these two cards, they would without a doubt choose the 2GB 6950 card for only $50 more cause they will think "WOW! For only $50 more, I can get a card twice as better". But no, it's not like that.

So I've tried searching around, and I can't really bring up any results to what I'm actually trying to ask. I realized I didn't know this when I stumbled upon a 2GB 560Ti (which I honestly didnt know they had) on NewEgg. I'm going to buying a new PC later this week or next week, and I already have it in my cart, just waiting for the rest of my money to get here to pull the trigger. I previously had a 6950 2GB Twin Frozr III, but after just browsing around the GPU section, I found the 1GB 560Ti Hawk which has just about the exact same performance, if not better than the 2GB 6950 Twin Frozr III.

Now I'm wondering, how can a 1GB card have just about the same performance of a 2GB card? I have a few thoughts, such as the video memory only means how far you can stretch it out, not actually how well it performs. So, what's the answer?

The 2GB 560 Ti is slower by quite about than the 1GB 560.

off the top of my head i think it is gddr3 ins tread of gddr5 so it has less bandwidth

Edit: The 560 would max the memory usage a long time before the 6950 due to the size of the resolution so the bigger it is the better performance :S

Well most games don't even use 1gb of vram, there are only a couple that actually do. When play at lower then 1080p that extra 1gb of vram you get from the 6950 is unnoticeable because you're res isn't high enough to use it.

If you are playing at 1080p or less a 560ti hawk will probably out perform a stock 6950 2gb (in my experience with the cards). plus you get cuda and physx

If you play at a res higher then 1080p get a card with 2gb of vram. Also, stick with the 6950 2gb if you are planning to do a multi monitor setup for eyefinity.

Greater memory bandwith gives you more allowance for higher resolutions. Hence, a 2GB graphics card will yield better frame rates at high resolutions (e.g. multi-monitor set-ups) compared to one that has only 1GB of memory.

On the review that you've seen, where the 560Ti outbeats the 6950 is might be due to the fact that the Hawk series of MSI is meant to be faster than their Twin Frozr Series. Otherwise, the 560Ti and HD6950 are pretty much on par with each other.

Also, to answer why a 2GB card performs about the same as 1GB in the review is because they are using a control resolution (e.g. 1920 x 1080) where both cards are tested to see which yields better frame rates at the said resolution. It's like a doing a 1 mile drag race between a Ferrari and a Lambo, trying to see which one is faster.

I never plan on using more than one monitor. At the moment the PC arrives, until around Christmas whenever I'll have the money to upgrade, I'll be using a 17" Acer monitor at 1366x768. I'll be able to max everything at that reso no matter which of the cards I get.

I'm planning to get an ASUS 23.6/24" 1920x1080 around December, but I'll never use 3 monitors to game cause I literally dont have room.

The one thing I'm kind of asking myself is if 1GB of memory will be able to to max out GTA IV. I know without a doubt that a 560Ti 1GB and a 2500K can max the game out of everything at 60fps at 1080p, but for draw distance, I'm not sure. It sounds like if I want to max draw distance at 100 as well, I might need more memory.

This. Video RAM is a very poor indicator of a card's performance.

They perform similarly because at 1200p and below because 1GB of VRAM is sufficient to store frame data. All memory does after all is store data needed for the GPU to render each frame.

If you don't need the extra storage space, then there won't be an appreciable difference between the two.

The extra VRAM makes a large difference when you increase resolutions though, and at extremes like 2560x1600 and surround resolutions, the 2GB 6950 would have significantly more headroom.

This is incorrect. The 2GB 560 Ti also uses GDDR5 and performs the same as the 1GB variants.

You can max the game out at 1080P using a 2500K and a 560Ti surely. GTA IV is CPU Intensive game mainly because its been poorly coded by the developers. Either way, if you opt to get the HD6950, you'd still get pretty much the same result at 1080P.

You'll more likely to get higher frame rates with overclocking your i5 2500K and of course more if you overclock your graphics card.

if someone were to add a second monitor for non-gaming needs, in this case would the 2GB VRAM make a difference?

Nope. Standard desktop usage barely uses any resources.
