I also have my doubts.. 1536 cores @1.4Ghz? 1536 cores with hotclock in such a small chip? Or maybe NVIDIA invented something like Hyperthreading, with 768 cores behaving almost like 1536, and thus the system actually reports the latter? Just speculating here, because I could see 768 core with hotclock on such a small chip, but having a hard time coping with 1536 o.O

And now some info that seems to talk about Hyper-threaded CUDA cores :O
I do not have any sources, neither I had seen this link before it was posted on Beyond3D.

Holy sh!t you might have called that one! Very nice!

you are talking about this as the source, correct?

We need a better translation

Yes, and yes. However, why would NVIDIA talk about Hyper-threading at all, if it wasnt relevant?

i don't know and i am very eager to find out. That is why i asked for a better translation.
-- some things we are hearing with Kepler, i thought were coming with Maxwell.

It wasnt being compared to hyperthreading then but the idea was this. The cuda cores spent a whole lot of times on wasted cycles. This was burning energy doing nothing, zip. cycles burning energy but cores with nothing to calculate. To improve performance per watt you need to keep the cores from wasting energy. This is a major focus. You will see nvidia implementing ways to keep their cuda cores crunching and eliminating wasted cycles. Its not specifically hyperthreading, as that is an intel term and solution. But it is the same idea that created hypertreading: keep the cores busy and reduce the wasted cycles. Threading is a great way to keep the cores with data at all times.

Eliminate wasted energy on cores with nothing to do. This is a major goal at nvidia, and it we could see solutions make it into kepler!!!!

That sounds like an enhanced scheduler coupled with good gating to me.

Probably a lot of cache also

i think you said that

in completely unrelated news ... my bags are packed
-- all carry on .. i'll be damned if i pay $50 (RT) to check a bag for a short flight

I always try to fly with Southwest when I travel.

i ain't paying for the ticket
