What ever happened to dual core GPUs?
My guess: too hot. It is easier to fit two 100w heatsinks than one 200w heatsink, especially in the cramped space of expansion slots.
Too hot and no real benefit over a bigger GPU. A dual GPU die would use more transistors than a GPU with twice the SIMD cores or ROPs and the latter would perform better anyway. Thanks to the highly modular designs of late GPUs can be harvested to various degrees and the result is better than harvesting based on cores, since you can save up more than half of the chip.
A dual core with two dies is kinda pointless for GPUs too, because of the reasons FordGT mentioned. Two separate dies don'¡t afffect performance from two dies on same socket, because latency is not a concern in GPUs, not to the point of CPUs.
cause cypress is fucking bigger than the fucking rv770/rv790
Jesus, these next gen cards just get bigger and bigger. Wouldnt surprise me if a new form factor of case called "OVER 9000" had to be released just to fit these monsters in.
dammit man.. that's gotta be 2 sig quotes in a week!
:d :d :d
it's OVER 9000!
but seriously... 13.5"
which cases CAN fit it i wonder
No idea, but its cards like that that make modding essential.
btw.. if it's so long
how come it doesn't bend or something?
Because PCB's have to be rigid, you just couldnt make them out of flexible materials.
like.. won't the weight of the card bend the like.. ram chip looking bit when it's inside the PCIe slot?
if you know what i mean
Erm the ends of graphics cards can flex and bend off to one end slightly, but im sure that manufacturers would fully test any chances of flexing / snapping before releasing the product for sale.
Good point though mayo
woot! i made a good point
when they make these cards can't they like.. instead of puttin the GPUs next to each other
make like a double decker card
but with one gpu and fan pointing up
and the bottom gpu and fan pointing down?
the middle bit would get rather hot though
Aren't those scores a bit low? That's like.. 5k 3dmarks lower than my 275's in SLI with only 18k CPU score...The driver is definitely not optimized.
perhaps because it hasn't been released yet?
Driver optimisation most likely. Plus, its an ES so it may not be fully up to spec.
That may be why AMD had requested the benchmark results to be pulled.
So why ATI made the Rv700 with two GPUs instead of a single 512mm² die?
I am not disagreeing with you, it is not a rhetorical question, I just want to know
EDIT: Oh, just saw the FordGT post, yeah, probably because it would be freaking hot
Most likely yields, and therefore, cost.
exactly what I thought.
Two GPUs (the x8x0 x2's) is different to two dies on one GPU (like the way intel made their C2Q's)
This news makes me want to go for a second 5870 all the more, My thoughts are the clocks will be final to work thermally.
that is one longass card, if Nv really pulls out a Fermi card as short as their mock up that (might) trounce a 5870, I know what my money is on, a card this beastly can't be that cheap to make.
also if early adopters of a 5870 go this 5900 for trifire, their original 5870 will be held back to the clock speeds of this guy, and given GPU scaling at 3-4 gpu's, I'd MUCH rather have two awesomely clocked 5870's.
13.5inch.. damn longer than mine.....LOL
dude.. erm.. sorry to backtrack.. but what is a "yield"?
•be the cause or source of; "He gave me a lot of trouble"; "Our meeting afforded much interesting information"
•give way: end resistance, as under pressure or force; "The door yielded to repeated blows with a battering ram"
•render: give or supply; "The cow brings in 5 liters of milk"; "This year's crop yielded 1,000 bushels of corn"; "The estate renders some revenue for the family"
•concede: give over; surrender or relinquish to the physical control of another
•give in, as to influence or pressure
•move over: move in order to make room for someone for something; "The park gave way to a supermarket"; "`Move over,' he told the crowd"
•give: cause to happen or be responsible for; "His two singles gave the team the victory"
•concede: be willing to concede; "I grant you this much"
•succumb: be fatally overwhelmed
•bring in; "interest-bearing accounts"; "How much does this savings certificate pay annually?"
•output: production of a certain amount
•give: be flexible under stress of physical force; "This material doesn't give"
•return: the income or profit arising from such transactions as the sale of land or other property; "the average return was about 5%"
•cease opposition; stop fighting
