Besides nothing has been delayed, there was no original 16-core version. You are telling nonsense again. As usual. On older slides you can read "8 and then 16 core SoCs ...". Which clearly shows that...

Seattle was never intended to be a mass product initially. It was an evaluation product to get the ARM software infrastructure ready. Keller clearly said that on the Core Innovation Summit. Seattle...

Source?!


As long as we don't have official info from Intel there isn't killed anything.

I don't think it will have shared L2. 512 KB dedicated L2 should have much lower latency (<=15 cycles).

Maybe for SSE, but definitely not for AVX. Or in which world is 4x 128-bit more than 2x 256-bit if you process 256-bit instructions?



Not really. First, it's basically one site, WCCFtech. Other...

Not destroy, but comparable. Haswell already has 2x 256-bit FMA.

Yes, I think it works like a LLC. Intel used something similar on their Iris Pro processors.



Why? There are a lot of processors which have more than 512 KB L2 per core. Prescott, Windsor,...

It looks more like an ARM cluster. 4 cores, dedicated 512 KB L2, 8 MB shared L3. Not really surprising if we keep in mind that Zen is K12's sister core.



And what about previous Opteron APU...

No, I don't. I talk about facts. On a dense throughput design every watt and every transistor counts. You are just typically closing your eyes, ignoring facts.

I don't think so. I see one major problem with MorphCore. When it switches to in-order mode there is still OoO logic that is unused and wastes energy and/or transistors. So, a clean multithreading...

Not really. You are just searching for weak arguments about what doesn't make sense. You neither describe MorphCore, nor its goals.

But you said "Jaguar/Puma style". And that's still nonsense. It's like saying Cortex-A57 is Cortex-A53 style.


Then give us a source for this claim. But as usual you will not be able to do so....
