AMD "Piledriver" refresh of Zambezi - info, speculations, test, fans

[fakhrain]

Wrong

"Agena" DR-B2 = Phenom 9500
"Deneb" RB-C2 = Phenom II 940

"Zambezi" OR-B2 = FX-8150
"Vishera" OR-C0 = FX-8350

Similar schema.

"Agena" DR-B2 = Phenom 9500
"Deneb" RB-C2 = Phenom II 940
"Zosma/Thuban" PH-E0 = Phenom II X4/X6

"Zambezi" OR-B2 = FX-8150
Engineering Sample "Zambezi" OR-C0 ≠ FX-8350
"Vishera" ??-?? = FX-8350

Corrected

what about the Family name?

[vietthanhpro]

Page 325 (Software Optimization Guide for AMD Family 15h Processors)

AMD family 15h and AMD Opteron™ systems range from single-node desktop to two, four, and eight node servers with the potential for even larger systems. Each node in the AMD family 15h system consists of four compute units attached to an integrated memory controller and up to four HyperTransport™ links. Models 20h – 2Fh consist of up to five compute units and models 10h – 1Fh consist of one to two compute units.

Now we have Piledriver in a server CPU

"The new and previously unannounced AMD Opteron processor is a custom designed octal core 2.3 GHz part based on the new "Piledriver" core, and supports up to 64 gigabytes of DRAM per CPU. "

We spent our first day in the St. Regis San Francisco Presidential Suite briefing journalist on our latest AMD technology! One of the most popular demos is our “Vishera” FX chip running at 5GHz on water cooling! Check out this picture of the rig!

[tbone8ty]

double post

[EniGmA1987]

What case is that? Is it just me or is the motherboard turned 90 degrees?
Also, 5GHz with what looks to be Corsair H80 equivalent cooling sounds pretty good. Lets just hope that is average and not special binned from a whole tray to find that one.

[tbone8ty]

its the silverstone raven type case, yes mobo is turned 90.

5ghz tells us nothing

just release the darn thing already! So we can move on to steamrollers

[FlanK3r]

5 GHz is no problem for gaming example...I run with my average Zambezi 5 GHz+ Cinebenchs.

[muziqaz]

Flanker, we all know that you are very lucky with your chips. The clocks you achieve we can sometimes just dream about

[BeepBeep2]

5 GHz Cinebench is doable on all but the most trash FX chips
Cinebench is also no indicator of stability...

Just like 4 GHz+ air Phenom II C2 was a joke, 5 GHz+ air Bulldozer was even more a joke, can't do much at 5 GHz+. My 4.8 stable chip s a brick when gaming at 5+ on water.

2600K will fly all day at 5 GHz...with noticeably better FPS too boot

[Zeus]

My Phenom II C2 was Prime stable at 4G on water. 5G on my Bulldozer was just benchstable, nowhere near Prime stable. Both my 3770K´s can do 5G, maybe even Prime stable but it takes rediculous amounts of volts.

Bulldozer seemed to have a large margin between fully stable and cpu-z stable. I'd say some 500MHz at least.

[FlanK3r]

Beep: I can not agree with all...

1)Cinebench is one point of stability, because is stressing CPU/IMC/uncore. So Cinebench is one part of stability for daily using, gaming. Of course, I must try Cinebench iun example loop 10x. ANd what is real stability? This discussion was here one year before? Everyone man says something different. For some is it gaming of BF3 or SII or Dirt etc. Someone say you u must stress CPU at least 24h PRIME95, some next no, this is not true, ideal is 1H OCCT. And next guys say you about BOINC and some guys say you "if your PC not restart or crash in use, after you have stable PC". And this is maybe the real point....I never stressed my PC xx hours in PRIME and my current PC never crashed (I using FX from November 2011).

2)If will be lucky, you can find 5GHz really stable FX (I have not it).

3)again, its not true. My 2600K is not stable at 5 GHz and with Maximus IV Extreme....Not all SB hit 5 GHz stable, maybe 30% yes and others are topped at 48-49x turboboost.

ZEUS: right ...example. I testing with AOD now, because Im tired from PRIME support for FX (and the same problems with IB vs difference version of PRIME...). Example. My FX topped at 4850 MHz stable, Cinebench near 5100 MHz, superpi 5300 MHz, validation 5400 MHz with all cores.
Ivy? 4700 MHz stable, 4800MHz Cinebench max, superpi 5050MHz, validation 51xx MHz max.

[Zeus]

Hmm your Ivy is not great then. Mine will do 4.8G Pime easy, 4.9G with some volts. Runs Cinebench at 5G 4c 8t, SuperPi at 5.3G 4c 4t. I have two Ivy's both underwent surgery and got coollabratory Ultra tim. This takes off at least 15ºC and helps a bit to push things.

Sorry for ot ramblings.

That's more 15% which can't do 5GHz, even less. You were not lucky at all, that's all.

Just look this thread on HWBot and you 'll see by yourself.

[FlanK3r]

Olivion, you are smart guy, thinking...HWbot is community of OCs, do you really mean, they have only one CPU? No, most of them tested few chips and show only the best results. And some OC star binned form many, many chips.
This thread is only Massman guide how to boot at max multiplier. Doesnt mean stability. My SB boot at 53x to Windows with this settings, but is stable "only" at 4950 Mhz .

Sorry, did I imply that all 2600K do 5 GHz? I didn't know I seemed so stupid.
Some 2600K do. No FX do. That's about as simple as it gets...

You can push 1.7v into FX on ambient cooling methods and it still won't do 5 GHz stable...

For further reference, I consider 1-4 hours of P95 stable, or maybe 24/7 WCG, and by the way Prime95 is not just a stress test program but a legit research program used by many people 24 hours, 7 days a week, 365 days a year.

MSRP for 8150 on release was what, $250, and sold for $280 USD? At the time the 2600K was selling for $300 and in gaming up to 50% better as well as many single threaded programs. They just milked all the guys with big pockets and small brains until they couldn't anymore and prices went down...

Now the price is adjusted accordingly but still, this CPU is not worth a $*** to the end user unless doing heavy multi-threading and on a small budget, as well as not caring about their electricity bill.

[Zeus]

You're forgetting the Premium price tag of high end AMD boards like the Crosshair V Beep. I have yet to see the first 5GHz stable BD on air or water, has anyone ever seen one? Sweetspot for mine was around 4650/4700.

Oh yeah, CHV is the only decent do-everything board for BD, CPU and memory... how much? $240? alright.
Meanwhile decent and useable P67 and Z68 boards selling like hotcakes for $120-200

I got my MIVE for $140 used...

You were unlucky with your 2600K. Doing 5GHz stable with good cooling and good mobo is very classic with SB, trust me.

Regarding Vishera, I sincerely hope AMD take the good turn on power consumption and, by the way, better frequencies.

I just don't think he was being enough like Christian Ney.

where?
maybe I'll hit more than 4.8Ghz on MIVE (stable)

[BeepBeep2]

Gunslinger here @ XS.
I said used.
I've seen as low as $150 from other people, I know that was a steal.

The board works with Ivy fine on latest bioses too according to some guys here, main problem is that max multi is still x59 for those on LN2.

I agree with FlanK3r, for at good reason - My FX-8150 is 100% stable@5ghz using a simple Mugen 2 aircooler, im pretty sure i can play games at 5ghz all day, if i like:

http://dnope.dk/download/file.php?id=18

This screenshot was made @ 23° room temperature. Cinebench is harder for my CPU to run stable, than my games are.

If i was going to play games alle day at 5ghz, i would preferer this air cooler insted(To be sure, im not harming my CPU in any way): http://www.overclockersclub.com/revi...eks_ph_tc14pe/

[Zeus]

Then show an hour of Prime 95 blend at 5GHz please.

[FlanK3r]

but back to PD Vishera. Multithread will be again good. Sometimes better than 3770k in mutltihread (some videoencoding) and this is awesome. Average in multi near 2600k. With pure not optimized singl, I think, is not much to change with this architecture :-/....But still is it OK for normal users.
