And how, precisely, are they going to do cache coherence over Seamicro fabric?
Server SKUs are rumored to be 16C/32T and even 32C/64T, along with APU designs.
Broadwell Efficiency, not performance. Im having hard time to understand what that means...
BTW, don't you think it's just a teensy-weensy bit suspicious that AMD is able to fit 8 whole super duper Zen cores into a 95W power envelope on a process that is probably inferior for high performance CPUs than Intel's 14nm? What do you think those CPU cores are going to come clocked at? 4GHz at Skylake-like IPC? Very doubtful.
At 4GHZ pretty much not. Will likely clock at 3GHZ range.
The AMD presentation slides said 40% over Excavator which sounds very nice since Steamroller had double digit % improvements over PD......
Lisa Su's statement to investors, "on track for greater than 40% IPC gains" should already be enough if you jump to the logical conclusion.
......
lol, don't bother. People have been whining about wanting CPUs with the die space dedicated totally to CPU/cache, and yet these are the same folks who thumb their noses at the "E" line. Of course, the "E" line doesn't have the newest cores and those people will complain, but at the same time those very same complainers will say that the IPC increases per generation aren't all that impressive & they would be cool with an AMD chip w/ more cores at IPC lower than Intel's latest mainstream CPUs.
The logic of Intel-haters truly and utterly escapes me
IPC is useless if we don't know clocks. For all we know it could have skylake IPC at 2.5 GHz and hence be quiet useless.
Has there been any finfet CPU/SOC clocking at even 3 Ghz outside of Intel? Not that I'm aware of. Heck only CPUs outside Intel reaching 3 Ghz were from AMD. So the capabilities of process are for sure a big ?.
On 14nm, a broadwell-level IPC 8C/16T no IGP die would be tiny yet would easily sell for over $300.
Well now that i thing about it, they could aways play the same game as Intel and release a 4C 8T small die at sub 100mm2 for the desktop and entry Server market. It could be great to have a 4C 8T ZEN at $200 to compete against the Core i5. For the same price you could have more throughput but less SingleThread performnce, but with DX-12 games already in the market at the end of 2016 this sub 100mm2 die could be the next big splash for gamers.
And with this small die, they would actually be able to sell a 2C 4T CPU for sub $100 as well.
A good product from AMD might force Intel to stop that crap and start offering mainstream, high volume CPUs on mainstream budget motherboards that have 8 cores and not half the die wasted on a useless IGP. This is the low hanging fruit that AMD could easily snatch up. On 14nm, a broadwell-level IPC 8C/16T no IGP die would be tiny yet would easily sell for over $300. There are easy profits to be had here.
The problem with the Intel E lines is that it is a separate line. A separate line with more expensive motherboards. It is just another money grab. That is what I want to see end.

I will buy on day 1 given the condition that Zen 8C/16T IPC ~Haswell, $300-400 similar to i7 K series, ocable to 4.3-4.5Ghz, allow power consumption to go up to 160-180W overvolted, I am ready for watercooling with 16thread budget desktop monster, just 64GB ram is enough. And no more crappy TIM on a $400 cpu thx.
I'm actually optimistic Zen is going to be a big hit. If AMD can land somewhere beyond Sandy Bridge single threaded performance and offer 8C/16T of that for around or just north of 6700K pricing I think they will find a good niche for themselves. They don't have to beat HW/BW/SL per thread performance, just get close enough to sway people who are ready to leave quad cores behind. Even in my case, if they could sell me 8C/16T of say, Ivy Bridge performance for about $380 I'd probably replace my 3930K with something like that.
I'm cautiously optimistic.
Don't really need more per thread performance with my 3770non-K. More cores however would come in very handy. Going from 4C/8T Ivy to 8C/16T ~Ivy would make a nice upgrade for the right price. Coupled with a decent platform it could be successful.

I assume we leave die area out of the equation.I just cant believe people still think (assuming the performance is there, a big assumption) that AMD will sell a 5960x equivalent chip for 300-400 dollars. I dont care how small the die is, it is just not going to happen.
What's that all fuss about efficiency. Intel bets everything on efficiency, why should AMD try to compete with that directly. Look how well Excavator clocks even with high density libraries and 28nm process, why would nobody except AMD to make Zen also to target very high clock speeds. Laptops and hippies aside, real enthusiast will buy even quad-core Zen if it bring clocks in neighborhood of 6GHz with at least SB level IPC even if it consumes quadruple of power versus Intel offerings(remember original Ahtlon). IPC is the hard part for AMD, high clocks should be easy target, even IBM managed that with Power8.
