Wait for 4gb 770 or get 2gb now? - Page 3

post #21 of 27
I'd recommend the GTX 780 3GB from PNY. Scored one for $600.00 and it performs very well.

384-bit+ is not a bandwidth, it is a bus width. The bus width is the multiplier for bandwidth, but it does not determine the memory bandwidth. The GTX 580 and 480 had a 384-bit memory bus, but it had a memory bandwidth of 192 GB/s, the same exact speed of a 680, and slower than the 770.

Technically in a way it does determine the memory bandwidth.


(2*Memory Clock * Memory Bus / 8) = Memory Bandwidth


Example:

2 * 3554MHz * 256bit = 1819648

1819648 / 8 = 227.5GB/s


Which is the exact memory bandwidth of my GTX 690:




The GPU itself on the GTX 580/480 was slower than the GTX 680 obviously but memory-wise it actually was comparable. The memory performance was a major limiting factor on the GTX 600's being it was limited to a 256-bit bus and only had a 6GHz effective clock speed (or 192GB/s as you said). The memory bus helps with loading and unloading textures from the VRAM faster. Essentially it is the amount of data per cycle that can be processed by the memory controllers (if I recall).

Yeah, I said this. I'm making the point that you can have a gpu with a 256-bit bus that has more bandwidth than a gpu with a 384-bit bus. (770 vs 580) I think the bandwidth that the 770 has is enough to make use of 2GB+ of memory, as it can transfer 3.72GB 60x a second.

It's not that it won't take any advantage of it, but the difference it makes is minimal.
If it were a totally new card I wouldn't speak ahead of seeing how it does, but a 770 is just a GTX 680 with slightly higher clocks.

If you want to know how much of a difference the 4GB makes (or doesn't) just take a look at 4 vs 2GB GTX 680 benches / comparisons.

Other than Crysis 3, all other games are a safe enough distance from 2GB that I wouldn't worry about it. And even if some game comes up that crosses 2GB, so what? Drop some AA or AF settings down a few notches until the 800 series releases, and then upgrade to a 3GB, 4GB, or 6GB card to max out that particular title (should it be necessary).

This is purely speculation by the way.

Yep, pure speculation.

A heavily moded Skyrim will laugh at 2GB of vram.
Max Payne 3 uses more than 2GB when maxed out.
Bioshock infinite uses more than 2GB when maxed out.
Serious Sam 3 uses more than 2GB maxed out
A heavily moded GTA IV will use more than 2GB.
BF3 uses more than 2GB when maxed out.


GTA 5 (ENB) will also most likely use more than 2GB as well..

To stay on the safe side I would say 3GB is the sweet spot unless you don't use any eye-candy whatsoever @ 1080p.

Thread Starter 
Just pulled the trigger on this one:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814125462

Got it for $430 with promo code and free shop runner shipping.

Decided instead of waiting for Zotac to get this one with several perks.
1. Higher stock clock
2. Most likely runs cooler
3. 1 year longer warranty
4. Hopefully will overclock more than the Zotac


Edit:
I guess it wasn't really a promo code. Newegg sent me a 10% off up to $20 on my 2nd newegg account I hadn't used yet.
