AMD Piledriver rumours ... and expert conjecture

[Reynod]

We have had several requests for a sticky on AMD's yet to be released Piledriver architecture ... so here it is.

I want to make a few things clear though.

Post a question relevant to the topic, or information about the topic, or it will be deleted.

Post any negative personal comments about another user ... and they will be deleted.

Post flame baiting comments about the blue, red and green team and they will be deleted.

Enjoy ...

By now I'm sure most of us have read the 7970 "preview". I want to say that is shows AMD still has it. Maybe, just maybe, they can pull something out for PD.

No

 

[saint19]

:lol:

Do you prefer a lie? New BD and PD will be better than SB, SB-E and even IB 😀

 

[viridiancrystal]

I could at least hope for some improvement. It probably wont be good, but at least a little better. I wasn't aiming for: "better than any product on the market". More of a: "Our best processor ever!"

I just was joking, sure will performs a little better but as soon as IB comes out that PD will die.

 

[viridiancrystal]

IB is tick though. It's not supposed to be a huge improvement over SB.

 

[saint19]

PD is only to be 10-15% better than the current BD and that's not including the stepping revision BD either..
and I was laughin' because I agree..

as for Ivy, if you have Nehalem (i5-760 to i7-880) or current SB (i5-2500K) AND if primarily talking about gaming
there is NO NEED to move to Ivy.

Say that to my wallet 😀

there is little room for more truth in this post.

 

[viridiancrystal]

10-15% improvement on PD. Makes me wonder. If BD is really so bad (we all saw it in the SBM's) will PD be worth it even with such a performance increase?

 

[viridiancrystal]

That is true. I hope AMD keeps up with the MB compatibility. Buying a new MB ever time you go to upgrade must get irritating.

@mal I am running the FX-4100 @ 4.1 (-0.5v) on the GA-990FXA-UD3 and everthing was fine until I added a GTX 560ti (2 days ago).

The multiplier is dropping from x20.5 to x16 even though the CPU temp is hovering between 35 and 40C. The only thing I can think of is the TIMPN2 sensor (which will not show up in EasyTune) is reading at 50-55C

The card is exhausting half the heat into the case but apparently the 2 120mm fans I added while installing the card isn't enough to get rid of it. I have two more to install but I need some molex to 3-pin adapters first.

I dont know what the sensor is reading because the 'Board Temp' is reported at ~38C in EasyTune which corresponds to TIMPN1 but as long as it shows those high temps the board is downclocking the CPU like mad.

You may not have the same problems with lighter use (my system is at full load 24/7 for F@H) and better cooling but the FX-4170 is supposed to run at higher clocks with a higher TDP.

 

[lilcinw]

LOL yeah you would like that! :lol:

I am afraid of what will happen when I add a second in a few months. I need to figure out the cooling situation before then.

I think may be the south bridge I am not sure. I have room to throw a fan on the side panel for intake and an additional for exhaust on the top.

I want to get all of this ironed out before PD is released (that means I have 18 months right? 😀) so I can decide on my CPU upgrade without being concerned with TDP.

TMPIN0 = Sytem (Motherboard) Temp
TMPIN1 = CPU Temp
TMPIN2 = Northbridge Temp

Uninstall Easy tune, that only work for...uhmmm....use space in your HDD or SSD

 

[lilcinw]

I was using it for the fan profile but I have even disabled that so I am about to.

 

[lilcinw]

Yeah I loaded up the 'driver disc' and the first thing it installs is some kind of Zynga crap.

I thought one of the benefits of DIY computing was no bloatware.

 

[warmon6]

it's EVERYWHERE....

Agree.

 

[de5_Roy]

is it true that trinity (afaik will use piledriver cpu core) will have vliw4? then will it be impossible to hybrid-cfx trinity with higher end radeons like 77xx (76xx too?) and higher?
after reading the 7970 article, i am more hopeful than ever. amd has always delivered on gfx cards and fusion apus. cpus... not so much.

For real? XD

And trinity wasn't gonna use GCN IIRC; it was gonna use the VLIW4 seen in the 69xx series. Lemme go get the link to confirm that.

Cheers!

EDIT: I've only found rumors and conjectures, bur nothing confirmed about the 7k series in Trinity xP

 

[ltdementhial]

Phenom II X8 according to XbitLabs

http://www.xbitlabs.com/news/cpu/display/20111222231004_AMD_May_Be_Preparing_Phenom_II_X8_Microprocessors.html

the thing that makes me think is the ClockSpeeds 2.8 Gzh max jezz i don't know what to think...maybe they're Failed FX with locked Cores..or as the're saying in AnandTech...Fx with L3 Cache Deactivated.

 

[amdfangirl]

Or relabeled Mangy-Cours given the high TDP, low clockspeed.

 

[truegenius]

another zambezi

 

[amdfangirl]

I'm hoping for the best option.

 

[fazers_on_stun]

^ Thought AMD had already stated they were retiring the old K10.5 design in favor of BD, but then they also mysteriously miscounted 800M transistors 😛 so who knows?

 

[we1shcake]

if they are am3 compatible, im buying one, but in reality i expect they are fx-8xxx that cant reach high clockspeeds so are being rebadged, similar to the old athlons, which were just phenoms with defective cache to begin with until the yields improved

if its the case
then they are spoiling the awesome phenom 2 series

but if it is a pair of phenom 2 x4 bridged together and in 32nm so as to keep its tdp in limit, then we can compare it to i7-2700 in multithreaded application.
