plan for launch is before end of year 2016 (end of Q4?) with better aviability in Q1 2017

platform: Summit Ridge

First leak of DX12 benchmark in Ashes of Singularity with RX 480

Based on this one ebnchamr we can say nothing about real performance of chip.

final ES clocks for 8C/16T CPU: 2.8/3.2 GHz (base/turbo)

My expectation: final clocks 3 GHz/3.5 GHz for 8c/16t, 3.4/3.8 GHz for 4C/8T, IPC close to Sandy Bridge, overall multithreaded performance 8c/16t Zen could be near the i7-5930K . The quickest AMD in single thread in history.

waiting patiently

I hope for a bit higher clocks for retails...Hope more than 2.8/3.2 as final ES (at least hope for 3/3.4/3.5GHz)

I've heard that benchmark of Ashes of Singularity is limited to the use of only 4 cores. This means that the ZEN should be on par with intels current / best offering.

The clock(s) will be around the 3 to 3.8GHz mark and a TDP from avg 65W to 95W.

It's too bad that the CPU itself will carry the NB from now on. This means we cant really use high FSB clocks without being lucky or not. Whenever buying a high-end motherboard, HTT's up to 350MHz where pretty much normal since the chipsets where almost as good as cherry picked.

Curious to see what ZEN brings into the party.

Crap. ZEN is competing!

YAY! AMD BACK.

dont hype till we get numbers

exciting times ahead! amd is back :D

The intel chip at 3.2GHz is clocked down to 3GHz to give a comparison. By the looks of it, clock by clock, it beats the intel with a marginal percentage on Blender. That very same chip of intel has a retail price of 1000$

This is good news. If AMD is able to crank up the clocks and actually pushes out good chips for good prices, they are defenitly back into the game. They have a very solid basis now which will see refreshments and better versions of it.

i am just saying this happens every time where amd shows one bench that is not in line with normal performance, and they overstate the bench by gimping something on the intel side like an old version or using the same install for both but testing the amd first. it wont be much longer before the AIBs leak benches and reviewers get samples.

Looking good. Still think i'm going to get another 6 months out of a refreshed AM3+ platform before Zen hits primetime.

There's only so much you can do the cheat on OSS benchmarks though. AMD is at least in the same ballpark as Broadwell-E. Piednol already tried to throw shade on AMD, accusing them of cheating on the bench, and he was shot down (read: had to delete his own tweets about it).

i want it to be real, i just do want to get hyped until 3rd parties bench it.

I think, we can say Zen will be solid (doesnt mean better than Intel). Blender was not the best benchamrk show for Vishera chips against Intel chips (example POV-Ray or R11.5 were better choices in 2012 as demo of performance).

But I agree, we must waiting for more tests (maybe in few months will be out few leaks). There can be better scenarios and worse scenarios.

Oh I know, let's not get too hyped about anything. I think I'd be on edge were I an AMD engineer or sales rep whose future rode on Zen/Summit Ridge/Zeppelin/etc., but as an enthusiast, I can take a relaxed approach. I went ahead and grabbed a 7870k off fleabay for ~$80 so I'm in no hurry to upgrade to a new platform.

the basic of Zen CPU is one CCX with 8MB L3 and 4 cores. So highest segment will have 2x CCX

It has been a long time AMD could even compete any benchmark with Intel clock to clock...

you cant compare clock to clock, because every architecture has different design. Some can hits easily 5+ GHz, another example 3 GHz.
You can compare example Core architecture design CPUs (Bloomfield, Gulftown, Lynfield, Sandy, Ivy, Haswell, SKylake) or K8/K10 chips (Athlon 64, Phenom, Phenom II) or Bulldozer microarchiotecture (Zambezi, Vishera, Trinity, Richland, Kaveri, Carizzo)

I just hope the CPU will be 'good enough' to bring AMD back into the green and to let me build an AMD box again without feeling like I am missing out. There's no need for Zen to beat Intel's top of the line right away.

Wccftech reporting that the higher end AM4 motherboards with X370 chipset are expected to be on sale in Feb / 2017. Motherboard manufacturers are to begin showcasing AM4 designs next month :)

Link

Hopefully they will showcase both X370 and B350 designs, so we can decide for ourselves if X370 has anything about it that will merit a wait of ~4 months.

I think, for X370 is too soon (for final boards design)

Yeah probably. Just seeing board specs would be nice but whatevs.

has anyone seen any real info on when we can expect AM4 boards of any flavor at E-tailers to buy?

I'm hoping we get some solid AM4 partner boards. Intel has received so much love for the last decade and it really shows.

There has been a change in the spacing for the 4 holes to mount cooling kit. This is to facilitate the extra traces coming out of the socket. Adapters or new CPU blocks will be needed.
