They have managed to put 4 excavator cores and 8 GCN cores on 28nm @ 246mm^2
Probably AM4 will allow larger chip around 300-350mm^2.

How much performance could APu have probably around R9 380.
Skylake CPU 4 cores 8 thread = around 120mm^2 right?
Polaris GPU that was showed on GDC 2016 = 120mm^2 right?

They could probably make much faster CHIP if AM4 will allow large chips.

Depends on the size of the cores at 14nm.

  • Zen APU /w 380 performance
  • SODIMMS on ITX
  • M.2 PCI-E SSD
  • VESA mount to the back of a panel

Imagine the potential for zen in a ultra low powered tablet with hbm backing up the iGPU.

Problem with AMD isn't AMD it's the 3rd Party vendors. They get too many nice deals from Intel that sway them to not even adopt different technology. Carrizo L is thermally cool enough and low enough in TDP to put into such devices.

I don't think these will achieve more than 3.5 Ghz on turbo and 4 Ghz on max OC.

That's good news if it's 40% more IPC at a significantly lower frequency. It may make higher benches than we can expect.

One of the reasons AMD is in this situation is their partners couldn't deliver and I'm talking about GloF.
Sure Bulldozer is not the greatest architecture but what if AMD would have released it a year earlier like they were suppose to and have Piledriver compete the next year whit Sandy Bridge?
What if AMD had at their disposal a 28nm node that would have allowed their Steamroller CPUs clock as high or higher than Piledriver CPUs while consuming less energy?

This is why the collaboration whit Samsung is essential for AMD. If Samsung delivers I'm sure AMD will also deliver.
I did have contradicting discussions whit Apple fans that live in a fantasy world and have the impression Apple made an order to Samsung and TSMC like you would order a Pizza and tell them how to make it.
A good process node is essential for a great processor that is what history has shown us, this is why Intel is ahead and this will be the reason AMD will become once again competitive on the CPU market.

Thats terrible actually that would put IPC at haswell but performance of ivy at best

They share an L3 and nothing else, AFAICT. Still, AMD may decide to only target quad core and above as the margins are too low on the lower end products.

I suspect SMT will also come with larger caches, so it may be disabled on dies with defected portions of the L3 - or possibly in faults in other areas. SMT is low cost, but not zero cost, for the die.
