AMD FX 8 Core and 4 Core Processor Systems Seen Running at E3

At the Electronic Entertainment Expo (E3) 2011, AMD made its revival of the FX brand identifier official. The company steered clear of actually launching anything, but reran the audience through the AMD Bulldozer architecture, something AMD first did way back in August 2010 (yeah, it's been that long!). Knowing the audience needed a lot more than just that, AMD ran live demos of gaming PCs running the new FX series processors, again, without giving away any performance figures.

AMD first showed the final box art design. The box of the eight-core FX Black Edition processor is a classy metal canister, while the quad-core FX chip is housed in a more common-looking paperboard box, the design of which matches the one revealed in a box-art exposé back in March. The gaming rigs shown run the eight-core FX processor on an ASUS Crosshair V Formula motherboard, with Radeon HD 6900 series graphics, with an Eyefinity display setup.
An instance of next-generation AMD Overdrive software is running, displaying a surprisingly low 19°C temperature on all cores. This could be a glitch, probably because AOD doesn't support the sensor interface of the new FX chips properly, yet. The other thing AOD reveals is that each of the eight cores is running on its own BClk multiplier value, ranging from 1.00 GHz (5 x 200 MHz), to 3.20 GHz (16 x 200 MHz). The core voltage for all the cores is displayed as 1.4V, again we suspect a low-level interface glitch.

tricksonNot how want mine to work . If one core is 3.2GHz then 16c would not be right at least it don't seem right . Looks like an up and down roller coaster ride to me . Wouldn't the temps be just as fluctuating as well ? I do know but to me this seems like a load of BS is all . I hope they come out soon so we can all see just what they are doing in real time real life apps . All this jumping the gun and looking at some half bald china man running the chip with windows system monitor ONLY seems a bit like giving a porn video with every one waring clothes ! NO MONEY shots ? ! WTH ? :cry:
The temperature did fluctuate

1 core @ 3.2GHz = 19*C
3 cores @ 3.5-3.6 = 20.5*C

Since this AOD and not Coretemp or some other program I am not sure we should believe that 1.4volt and 19-20.5*C readings till next month when the benchies should come out

OH, I have such a headache
seronxSet your house to 64F and turn off your cpus overclock and turn on the intel's equivalent of Cool'n'Quiet, I think its called E1C or Speedstep

I haven't used intel since Pentium 4 so I wouldn't know the names, You should get the same results
LOL yeah I could also slap on the TEC WB I have and get even cooler temps ! 0c any one ? Even with all that this thing is running a POS Stock cooler NO Way it is that cool ! And whiel every thing else is up and down the temps ALL stay the same ? NO WAY IN HELL BROTHER ! I call Bull Shit !

Well the AVG temp for i7 2600k with its stock cooler is 30*C which happens to be the AVG Ambient Temperature(±1*C)

and that CPU cooler is probably not the stock cpu cooler(I don't remember seeing copper heatpipes on my AMD heatsinks)

Whatever it is whatever is going on I will not believe it till I see some real world action not some half bald china man staring at a screen of windows system tools . And another thing 1.4 Vcore ? With all this going on I am taking it with a grain of salt as my bs meter is going off the scale !

The 1.4 volts to power the cpu you should take as a grain of salt since the redesign of the 990FX was higher the amps lower the volts thus making the 1.4 number false

then comes to the temps are being the same... The temperature reading there is the hottest component(the center of the CPU(That is where the sensor is at))

But yes take it as a grain of salt

Then you can go on to say that

AMD FX is on the same fab process as the Intel fab process

Both are using a version of 32nm SOI HKMG

Both can have idles below 20*C as long as the Case Ambient is also below 20*C

Ok got ya . I still want real world tests done then I can be a true believer :respect:

I will be more believing when W1zzard has it in his hands or more TPU people get them . I have found out the hard way that others are just not as trust worthy .

xBruce88xAMD does make heatsinks with pipes...

www.youtube.com/watch?v=gmD9jWYnQSQ
AMD heatsinks had pipes since forever(My previous statements are wrong,(I never had a stock cpu cooler always buy OEM ;)

Well yep that is the AMD Stock cooler(E3 comp picture)

Darn you Zalman spoiling me with your Nickel-Diamond plated copper/aluminum

aww i wanted to see how well that girl could drive a stick.
This is gonna sound awkward but....

I am more interested in the computer :nutkick:

btarunrFor Phenom, AMD started hyping Barcelona right when Intel released the Core 2 series. That hype campaign was a lot more aggressive. You had senior VPs of AMD publicly saying that Barcelona will "crush" Core 2.

That isn't happening now. The "FX" name first became public via leaks, AMD hasn't commented on performance to the public till now. When talking about the Bulldozer architecture, AMD avoided claiming it to be the fastest processor architecture, or something that will be the fastest in the market.

If AMD was confident that FX will lead, you can bet your bottom penny that they would have launched FX months ago, or would have made benchmarks public.
That's exactly what I think, bta.
HD64GExactly!
Exactly wrong. A fan moving air does not cool the air. You cannot cool below ambient even with water cooling. You have to use a TEC, or phase, or something along those lines.
inferKNOXProbably outlandish, but definitely not impossible.
The fans required to drop the pressure enough to significantly alter the internal temperature of a case would probably need to have impractically high strength and thus would probably be uncomfortably noisy.
It remains, however, physically possible to achieve such result.;)
Not in the conditions present in a typical computer case. This theory is not taking into account the heat that the other components dump into the case.

The simple truth of the matter is, it is impossible for the layout shown to cool below ambient using standard heatsinks or even water cooling, and it is also impossible for the typical enthusiast to build a setup capable of cooling below ambient using only fans, and standard cooling.
pantherx12No need for a heat exchanger.

Thing is he's right the fans needed would have to be phenomenal :laugh: Basically if there is less hot objects in their ( atoms and such) then there will be less heat.

As say you had 20 hot things in something x size. You'd have a tdp of 20 ( sorry for easy numbers, can't be arsed)

Where as if you had 10 hot things in x size you'd have a tdp of 10.


The theory is there it's just not possible with conventional designs.

(think about air high up in our atmosphere, it's cold as there's less air up there)
But also less heat dissipation from the cpu heatsink, as there is less to carry it away.
seronxSB only has 1 FPU per 2 threads as well

FLOPC is the same as SB at 256bit while in 128bit FX is 2x that of SB

(Problem #1 with this slide is it referring to 1 Flex FPU or all 4 Flex FPU in Zambezi)

But Intel doesn't call it an 8 core.

Wile EBut Intel doesn't call it an 8 core.
I can't explain the difference between

AMDs SMT and Intels SMT



As you can see AMD went from CMP to CMT

CMT is a form of SMT(Same under Taxonomy)

(Kinduh funny that they planned Bulldozer in a way since 2005)

seronxLooks like the case has a huge 140nm or is that 120nm fan on top so that can help that stock cooler alot xD
you mean 140mm (millimetres not nanometres)
so far bulludozer perf i can see, good enough for smooth play of dirt 3... so its at least as good as ph2. so nothing particularly new from e3 about bulldozer other than it works.

That is how you get it(You need $489 for the Eyefinity model)

I think I'd put the projectors in Portrait layout though to fill the bottom up a bit as well.

Nice, but something tells me it will cost ALOT more over here in AUS :ohwell:

cdawalleach core is adjustable volts wise on AMD server chips
Weird, I can't find anything on such tech on the net, including AMD home.
All there is is common split power plane (Dual Dynamic Power Management) that is, dedicated voltage sources for (1) uncore and (2) cores.

fixed

This really tells us nothing, given neither of those games are cpu intensive. :mad:
