AMD Bulldozer Finally!

Not really.
1.5v for a Phenom II was quite common ground, we handled the temperature fine.

You're using a relatively low voltage, and, while an impressive clock from an AMD perspective, it's not the highest it'd go.

You can't just say that the temperature problem is caused by people not knowing what they're doing.

I'm sure a few Xbox 360 launch models may still be kicking, that doesn't mean there wasn't an inherent fault with them.

if i Whack the voltage to 1.525v 4.3ghz on my 1090t the temps would go sky high

at 4ghz 1.425v it goes to about 55-57c under load
 
Interesting question for you lot, would an H100 handle the heat from a maxed out 8150? Running at whatever the max safe voltage is, clocked as high as it will go and still be stable?

And as a follow up question, how would that compare to a 3.8ghz 965BE C2?

This a "drawing conclusions" type issue that I can't seem to solve myself. At the moment my 965 is fine for my needs, but once I have an SSD or two, we shall see. Just thinking of upgrade paths, as I've read that my board (GPA-890-UD3H) will run a 8150.

I'm on about the old X4's, 1.5v on them was common ground, and 1.525v on a Thuban was extreme, because pumping that much voltage, you needed beefing cooling to deal with them. The temperatures on my 1055T at 1.55v at 4.375GHZ were 59C under Ibt, Prime would give like 55c.

It's the same with BD, when you actually push it, you need beefing cooling, you're not even nudging it :p

u didn't say x4's at first, u just said Phenom II ;).

also the Phenom II x4 and x6 voltage / temp specs are the same

i thought your 1055t was 95w? also u was using water cooling

also who to say BD do have hest issues.

every cpu gets a lot hoter when uppingn voltage/ clocks. it's down to the cooler

Yes it was 95W, but that's due to the lower stock voltage,.
1.15 at Stock, so putting 0.4v extra in it obviously increased temperatures quite a lot it'd run hotter than a 1090T at the same voltage IIRC, the power test programs all suggest that it'd be using more power too, Combat Squirrel who has it struggles to keep it under control at over 4GHZ for example, and he took my board and CPU.

Phenom II is an X4, I get I should have elaborated :p

And their TDP rating at stock is the same bar the OEM Zosma and 95W's etc, but they'll all behave differently when overclocking and overvolting hits the equation.

but a 95w has a higher max safety temp limit usely 70-75c

71c, but what's that got to do with anything?
I was only hitting 59c, but if I pushed any further, temperatures would go stupid, not from a lack of cooling, but the CPU's get less "efficient" I guess you could call it, which is where the Bulldozer temperature problems are coming from.

EDIT : That's not to say I don't understand where you're coming from, you've got BD and not seeing any temperature problems, your data is concise, but you look to have a good chip.

also theres 1090t's which are not as good as others which need more voltage and gives more heat, but it doesn't mean theres a heat issue.

its about luck.

if the chip needs high voltage of course u need great cooler.

Mins are higher on the Thuban.
Interesting, I'm sure people were touting BD was better for minimum's than even the Intel set ups.
But they're pretty identical in Heaven.
 
So average FPS there is the same when Zambezi is clocked 500 MHz higher...which is probably about the average expected maximum attainable clock over Thuban anyway.
 
Whilst this chip hasn't turned out to be everything we hoped I think it's an interesting development.
Has anyone got any benchmarks of how it fairs against the older Intel CPUs?

I currently have a Q6600 at 3.6GHz and was wondering if the 4 core version might be a worthwhile upgrade also overclocked on water? If AMD get the price right I think they might have something here. Only seen the 8 core reviewed but it seems to hit 4.5GHz on air (I would use water), be interesting to see a comparrison with the 6600.

4 core BD won't be any good has it is now
6 core BD oc'ed would be ok if u got a low end 2x or 4x
8 core BD oc'ed would be ok if u got a higher end 2x or 4x

basicly a 8 core BD @ 4.5ghz = a ~phenom II 6 core @ 4ghz

if u already got a phenom II 6 core don't bother with BD

yes a 8 core BD may oc to 4.8ghz - 5ghz but it's not worth the very small boost

I know we're all aware of BD's poor performance but here's some more benchmarks from a few days back by a user who isn't a professionally paid benchmarker. It really emphasises what a waste of money this chip currently is. What's really amazing is that my humble little phenom xII 550 got about the same Super PI 1M result when I had it overclocked to 3.7 or 3.8GHz, can't remember what my overclock was exactly.
