No, it hasn't so far because current architectures can only scale so much on a given die. If they can improve that with an architecture that works well in both TDP and performance at larger ranges, they can get far more products out of a single die.
This would indeed be a 'scalable' architecture.
Anyways, thanks for answering my question - you are simply guessing and have no source.
It was a proof of concept of what? Using an interposer? That does not mean that stackable graphics processors are do-able. Maybe they are, I'd just like a stronger argument than pointing to a product that stacked memory. This is not splitting hairs by any means. It is crucial as to whether or not it's something we can expect.
You made the claim, it's you who needs to support your assertion.
I've been keeping up plenty. Multi-GPU in the new API's is made harder due to not having the handy abstraction handling this in on the driver level. Notice how few DX12/Vulkan games support it? Obviously it can be done, but there is absolutely nothing to suggest it is going to be more supported than before, much less become an outright paradigm shift.
What are you talking about? I never claimed to have the answers to these things. :/
Anyways, I've learned very quickly you are not worth ever responding to again. You're rude, condescending, have no intention of supporting your arguments with anything meaningful, and also admitted you are financially invested in AMD. A cocktail for an absolutely insufferable discussion...
I really hope you dont talk like this to people in real life man.
