[WCCFTECH] Zen Opterons

[flanker]

Wow

 

 

In a discussion related to technology and market trends for the data center, Liviu Valsan (computing engineer at CERN) showcased slides which detailed AMD’s upcoming Opteron processors that feature their x86 Zen core architecture. The session not only provided details on AMD’s next generation processors but also mentioned Intel’s Broadwell-EP chips along with enterprise aimed storage and memory solutions.

Thanks for sharing1

I really hope that 40% instruction per clock doesn't come from the SMT (and they don't compare a 8c16T Zen vs 8c8t Vishera), and the clock scales well with cooling and voltage. Their 14nm capability is really unknown at this point.

 

The 28nm in Kaveri/Godavari still gives me nightmares (better IPC than previous gen but the CPU clocks scaling are not that good)

I got info Zen Opteron is 32 Core (16 + 16 in one die) with 8 Channel DDR4 Memory. So probably Zen Desktop will 16 Core with Quad Channel DDR4. And the most important i hope 40%+ IPC Improvement is from Excavator Core, not from older core. It will fun if memory controller is a beast like 4266Mhz Quad Channel for daily usage

7870K are not bad, but of course, the high limit is few hudnred MHz lower. Example my 7870K can run 4700+ MHz stable and its good iprovement from 7850K (4440Mhz).

Interesting looks Excavator and Excavator+ ( (Bristol Ridge) as last Bulldozer chips.

 

3400 MHz Excavator core without tweaks od system etc:

 

Results is better than 5100 MHz Vishera with tweaks and better than Kaveri at 4500 MHz with tweaks in 32M Of course, this is only in this benchamrk, so huge iporvement. Other will be less (+3% or so per clock)

Based on that data, the X4 845 Excavator is going to be really interesting then . I wonder when are those hitting the market, and how far can it be OCed by using BCLK (if it's possible).

[flanker]

me too Im afarid, there will be issues with higher BCLK overlcocking But I hope it could be break 4 GHz in OC

[Massman]

They should've released the X4 845 on AM3 :-/.

 

BCLK should be limited to ~133 MHz on boards without and ~170 MHz on boards with south bridge pll enabled. 170 MHz should be sufficient.

Weird thing about is I've got 2 7870k's that would only clock 44x/45x but I got a 7650k that could clock to 4.8ghz with less volts and a 7400k that was even better but temps are way better on godavari and can push 1.55-1.6v instead of 1.5v max

I'd hope that's case but kaveri maxed at around 130 while richland would run 170+ but I'm eagerly awaiting the 845 to be available at retail

 

Also anyone know which boards have south bridge pll enabled?

I was guessing Crossblade Ranger ... but yea, Kaveri only does 130 MHz. What the heck?!

 

If Zen is supposedly recapture the imagination of enthusiasts, they should really start building the enthusiasm now. The latest FM2+ stuff has barely anything interesting for enthusiasts (while it could actually benefit since the IGP performance is quite good).
