While the cores have multiple processing units for some things, wouldn't a multi core GPU be better than the current method of inefficient SLI and crossfire?
With SLI and crossfire, of average you will see around a 30% performance boost.
But when a chip like a CPU gets more than one core, the scaling is pretty much perfect.
Wouldn't a single chip with an additional core work much better?
it shouldn't be too hard for them to go from this
sry for crappy photoshop :)
it has been done with CPU's and it worked quite well for the core i7
PS the doubling of the GPU (2 dual core chips) also worked for the core 2 quad)
GPU's are already multi-core, they're just represented differently. The ATi Radeon HD5870 has 1600 cores.
What you're basically asking is that they double the number of cores on such a GPU from 1600 to 3200. That hasn't been done for the same reason that we don't have 12-core CPU's yet...because at current process sizes, such a chip would be too large. Yields would be significantly lower, power consumption would be unwieldy, and you'd at least double the heat output.
Maybe you'll see GPU's with that many cores when they get down to 28nm.
