Theres really no need for that. you can easily switch to Single GPU mode within the drivers & benchmark one of them. why the trouble?
I was just wondering why we didnt have any SLI benches to go along with the SLI pictures...

This Dual-Core GPU thingy is Bull-S*** AFAIK.
-either NV will launch a single core (Normal) 32piped card!
-Or NV hav already given up on the 32piped thing...they are focusing on 24pipe winner. and the possible 32pipe monster will show up after 6 months
-Or r520 is gonna FLOP big time. :p , and and nv knws it! (j/K)

Bingo. Someone finally figured it out.

Video chips are inherently parallel already (16, 24, 32 pipes). So a "dual-core" chip means absolutely nothing. The 6800U could be considered a dual-core 6600 (not really, but you get the point).

It's also very unlikely that nVidia has a 32 pipe monster in the back on 110nm process. It would draw too much power and output too much heat. Knowing that nVidia is moving already to 90nm, it would be on that process that they would release a 32 pipe ship.

If nVidia is waiting with a more powerful G70, it would only be a higher clocked 24 pipe card (probably ~470-480Mhz). Their architecture with the 6600GT on 110nm was very good, and having a chip run at 500Mhz is not unheard of.

True, but i think its just easier to make a small 16 pipe core on a 90nm process and just slap two of them together rather then making a huge 350-400mil transistor core with 32pipes.

Dual core GPU is just fodder for sites like THE INQ and rumour forums.

However, your fourth key is probably very true.

[MUYA]

hmm dual core? multi core....GPU has been around since multi quad blocks GPU :) or something like that

CURRENT GPU IS NOT DUAL CORE. The way architectures are laid are synchoronous rather than asynchoronous. bits sent in parallel arrays rather than serial bit transfer. That doesn't make a GPU Dual core :confused:
I haven't come across a GPU which has TWO cores on a single die. Maybe NASA has it, I don't know.

Exactly. Solid Snake seems to have let his imagination run wild.

[Kombatant]

Just a fyi. There is a reason you don't see people who actually know details about upcoming products posting in boards and giving you all the gory details: if they do, their sources will not trust them again with such info. So what they do is drop clues and hints (read: you must be able to read between the lines to get them).

So when you see people yelling OMG SHOCKING INSIDE INFO!!1!, have some reservations ;)

I think this thread should be locked. :)

That would be a very good arguement except for the fact that nvidia are marketing an SLI system at present which requires the screen split into TWO for TWO gpu's or every other SECOND frame to be rendered by a SECOND gpu.

Indeed, 2 seems to be the number of the moment , even some cards have 2 gpu's on them, which is as near to dual core as you can get.

I am not saying dual core is likely, but your reasoning above is, quite frankly, bollox.

:D

Because graphics is massively parallel dual, quad etc etc is more practical at present than cpu's going dual, but that is not stopping Intel or AMD.

You're missing the point. It's because they are already parallel that making a "dual-core" chip only means you would be adding more pipes (without going into too much detail), which is what nVidia and ATi have already been doing for years.

SLi does need 2 GPU's but that has nothing with nVidia supposedly making a dual-core GPU. We are talking of the engineering possibilities of a dual-core (on-die) chip, which, quite frankly, are just fanboy dreams.

Too many people think that since AMD and Intel are doing it now, it must be the "next big thing", and that nVidia and ATi should do it too. But they've already been doing it. :D

We're on the same page arguing the same point.

[Red_Shift]

I agree with both theories in part. A general apps processor can't be compared to a graphics processor. Making dual-core cpu's will enable more threads to processed at the same time, cpu's work is so different from pixels and vertexs calcs that they're simply not comparable. In a dual core the workload will be balanced between the 2 cores but the performance will be about the same as having full workload on a single core if specs grow linearly, so in practice it'll be the same (this is where I agree with karma). But dual core might enable different specs, for example, will a single-core gpu have twice the vertex pipes a core in a dual-core gpu? For example G70 has 8 vertex pipes, going dual core might enable 16(8+8) vertex pipes but that's extremely hard to put on a single-core gpu. Another difference is driver's and gpu algorithms efficiency, SLI never performs 100% faster than a single card and that's not only because latencies but primarily because of what I mentioned before.
As I said in a post before, dual-core gpu is like a SLI with lower latencies, so I don't see it feesable until we get to 65nm or smaller manufacturing process. Then dual core die size and heat dissipation probs and so on might be solved and going to a dual-core card would be cheaper than buying 2 graphic cards. By that time workload balance should be more efficient too.
Joining 2 cores into one die might enable different kinds of interconnections between the 2 and so in future we might see practical difference from a SLI system too. Even if each core has it's own cache, it might be possible to use a part of the other core's cache that would be sitting idle otherwise, those kind of things may happen in the future.
