Eight core Bulldozer overclocked to 4.63GHz

Written by Nedim Hadzic

1.5V for Super Pi
An engineering sample of AMD’s FX-8130P managed to hit a quite mouthwatering 4.63GHz.

The CPU should be AMD’s fastest Bulldozer offering and its eight cores run at 3.8GHz, or up to 4.2GHz with AMD’s Turbo Core 2.0. It has 8MB of L2 cache, 8MB of L3 cache, supports DDR3 1866MHz and is said to have a 125W TDP.

Pushing it to stable 4.63GHz and completing Super Pi required around 1.5V. You can read more here.

I wouldn't say 4.6GHz is anything special, its only +9.5% increase over what the chip is rated to work at (4.2GHz), ok i guess its on all the cores but SB hits 5GHz fairly easily and SB-E should do even better. Plus 22nm Ivy Bridge is only a few months away which you would think would overclock even better again.

My hope is that this is the stepping that has been sent back to get re-spun to increase the performance.

On saying that, 1.29 seconds for 1m SuperPI seems awfully fast!!

good to know,now when can we buy it, would it be this year or there's gonna be another delay?

Cooling used? 4.6 O.C. from 3.8 Ghz stock doesn't sound like a big leap, specially if the voltage needed was 1,5 V (stock being 1,2V?). If this was done with air cooling it might be acceptable but if it was done with water or more extreme solutions....fails to impress.

compared to 2500k @ 5gh which took 7.2 seconds..i wud saw this is insanely fast!!! 8)

Guys, this is early ES chip. And that guy OBR is known as a bit of a Intel fanboy. Where word 'bit' is a huge understatement ;)
That chip he supposedly have is clocked at 2.8ghz at stock.
and it is not 1.29s. Some digits were erased. 1x.x29s.
I don't really see the point of such kind of news or even blogpost. That guys really has some attention issues.

Looks like a fake - to good to be true. The Super Pi output window contains not the usual data (e.g. calculation time for every step).

Look at the following site for Super Pi results and reference screenshots: http://www.techenclave.com/overclocking-n-modding/techenclave-indian-technology-community-superpi-1m-193435.html

Nevertheless, I think BD will be a great midrange to highrange processor.

Yep, those screens are edited, and for and eight core processor, 11-whatever seconds isn't impressive. AMD failed again

for sure the reason, why the checksum got deleted and some other parts of the screenshot were removed or edited, is that this is a just a very poor fake.

btw i think bulldozer will do a great job, but please use your brain, before posting something like this

Quoting neo222:

Superpi results would be displayed as:

The suspiciously large gaps between numbers and the dot suggest that it's not
1.29 but actually 1x.y29 - meaning super pie is between 10 and 20 seconds.

You'll also note all the intermediary second figures that should appear above the "1 . 29s" in that column have been deleted all together.

What cooling was used? This is an engineering sample, but did it use the retail-revision?
