7970 vs 680 thread.

Any ideas why the 256bit memory bus is not holding the 680 back? AMD must have gone to 384bit for some reason (as did NV with the 580), but how comes the 128bit "downgrade" seems not to affect performance at all?

Can vendors increase that when they move away from the reference design, or is it set? Say with the 4GB 680 EVGA has promised.

AFAIK vendors are not allowed to change core specifications of the GPU like the memory bus. If NVIDIA want to increase the memory bus they will most likely create a new and improved GPU like the 560 TI 448.

Vendors can add more VRAM to a card, i.e with the 1.5GB and 3GB versions of the 580.

They can't however change stuff willy nilly. For example, the 560Ti 448 version was a brand new card released by nvidia, it was not a normal 560Ti modified by a partner.

So, the 4GB version of the 680 will have exactly the same memory bus, unless nvidia decide to upgrade the bus in a new version of the card, which I think is highly unlikely.

Unless driver maturity increases the 680 performance significantly, I shall be sticking with my 7970 until the next series of cards anyway, i.e GK110 etc.
 
just saying in case someone on here was thinking on getting a GTX680 as they were cheaper, now their the same price

I would buy the 680 if they were the same price, 7970 can be had for much cheaper than a 680 if I wanted one, 2 6950>70's are faster@1080p which I use, cheaper and sitting in my system for 14 months now.:D

Its actually not a good time to be buying graphics hardware, becuase when the next gen consoles come out next year, they might drastically shake up the market.

Meaning expensive £400 toys today are left looking a little bit silly.
 
The standard price of the GTX 680 will drop below £400 within a week or two. Once supply is readily available, the $ to £ conversion will get closer to true transaction rates.

AMD will also have to cut the 7970 pretty soon because it is slower out of the box than the 680. Maybe £375 will be the norm for these before the end of April, with 7950's dropping to £300.

Competition is good for prices.

The xbox 720 won't be announced at this years E3, Microsoft have confirmed this so I think a 2013 release is highly unlikely. 2014 at the earliest.
 
so, how should I expect a 680 to stack up to 480 SLI, sorry dude I'm completely out the loop.

Ive switched from 480sli to a single 680 performance seems pretty much the same in BF3 maybe a bit lower, only played fro about 1hour with this card though.

In haven and 3dmark 2011 its fair slower but I only care for in game benchmarks

It is FAR quieter than my old setup even when the 480's were water-cooled as i can switch back to lower RPM case and rad fans again as well has fair less power hungry

How cheap do you expect next gen consoles to be?
I paid a reasonable amount for my 360 after release. I don't imagine MS/Sony will be unleashing new consoles for extremely low prices.

Expensive £400 "toys" will probably just look the same as they always did.

USA rrp counts for absolutely nothing in the UK, as it stands the 7970 is cheaper than a 680.

Why does AMD need to reduce the price, for all we know they have been selling adequately for the last 3 months, AMD could have had loads of them ready, where as it's looking like the 680's are in very, very short supply.

As you voiced your opinion on the other thread so strongly over and over again about the price of the 79**'s being far too expensive, why pay the extra price of the 680's for very comparable performance?

Take into account both cards are enthusiast cards, used by enthusiast users and both achieve literally(without kicking it off all over again) the same performance give or take a scant few fps here or there.

My point is nothing to do with your choice on cards but more on bewilderment by your recent onslaught of AMD's pricing, to then contradict your own outspokenness and get a 680, whith price/performance equalling a 7970.
 
When the non reference 7970's start hitting the shelves with higher clocks, the performance gap at stock will be null.

This can either go one way, price wars with Nvidia and AMD dropping prices drastically..... or they both act stubborn and prices remain artificially high.

Unfortunately I think the latter will happen, would love to be proven wrong!
 
When NVIDIA/AMD drop their prices, retailers will have to also. I cannot see OCUK dropping their anytime soon. If they CAN charge £430+ then why not? This comment has been made before so feel free to ignore me :)
