Add that to Intel's CPUs in the graph and you see most of the runs are within 50 to 60 watts of extra power for the FX series. About as much as a normal light bulb. That's not much power in real life, I have several light bulbs running over 12 hours a day in my house and I would see maybe a $1 or $5 difference in my light bill if I shut them off. I also have a media PC running 24/7 in the living room so 50 watts is the least of my worries.
This is at full load also. Most people's PC are not full load for any significant amount of time. If you look at the FX series, idle power consumption from these same reviewers, AMD has improved since the Thubans. This is where the average PC sits for most of the day, idle to 20% usage.
You CPU is not at full load while gaming, watching movies/videos, surfing the net or balancing the budget. So unless you are folding at home or some other CPU intensive task 10 hours a day, these graphs are meaningless. The average user does not fold at home or run stress tests all day.
The OP is trying to convey this message but once again, you are all thread crapping. Good job! I really wish mods would delete the thread crapping posts and give out warnings for repeat offenders. Stay on topic for once in your life.

However, you miss a few points...
1) Poorer power consumption is only one reason not to recommend Bulldozer.
2) People who actually can fully utilize Bulldozer (i.e NOT gamers) probably do care about energy consumption (i.e. servers)
3) While Bulldozer may be better than previous AMD (and this is NOT always true), it still is cannot compare to Intel offerings.


In general, gaming is not a very good benchmark of a CPU.

Running the Heaven benchmark is primarily testing the power draw of that GTX 560 Ti. My CPU doesn't get anywhere near 100% usage with that benchmark running.
And in the benchmarks that actually do test CPU power draw, Bulldozer is way worse than Sandy Bridge...and worse than Thuban in most cases.

*edit* I forgot to finish my last sentence, lol.

But the problem is..

People were expecting said truck to be a Ricer Two-door. Which it isn't.

Ok, I agree. Bulldozer power consumption doesnt look bad, if you have no point of comparison.

326
Regardless, even as a quad core it's going to pull about the same power as SB and produce half the performance. It has bad performance per watt no matter how you try to present it.

And I see that you BD haters are still throwing around the same benchmarks from when BD was released.

These charts are no good anymore. This tests were done with apm enabled on bulldozer which makes them useless. There benchmarks are not up to date and do not show performance of BD today. How long are you guys gonna post up the same charts over and over again. BD performance today is a whole lot better than it was at release. When are you guys going to realize this. Stop posting useless charts and graphs that are months old. Get someone who has BD today with latest bios that disables all power saving features to post some benchmarks of BD (unlike the one you have hear).

You talk all this trash about BD but it seems that you cannot stop talking about. For someone who doesn't like the chip, you sure spend a lot of time talking about it. Either give in and admit that BD is a decent chip or get out. Its like talking to a 14 yr old girl thats not getting her way. Grow up already. Its getting real old.

It does compare to both 2500K and 2600K and 980x in some things like it was supposed to do. Not all things, just some. Like multithreading or multitasking. BD is great at these things. Some of you guys expected BD to blow away the competition. No this is not true. But it does throw some punches with intel in some cases. Again, not all but some. Just like amd said it would. For those of you who expected BD to be some amazing super chip were just misguided. BD is a brand new different architecture that is a fairly damn good chip for a first revision. If you look at phenom or pentium, they both were in a worse spot than BD was at release and they turned out to be great chips. Give it a little time and BD willl be the chip you were expecting but for now it does what amd said it would do.

Again, I am not saying that BD is a better chip that SB but it does compete with it in some cases. Not all cases but some I have to put emphesis on this because people like to put words in my mouth saying that I said BD is better than SB cause its not. But it does compare in some cases.

For the power consumption deal. When running prime at 5GHz my total system uses less than 550Watts. When gaming I use about 500-550Watts. I have compared the power usage of 8120 to phenom 965 and it comes down to about $4 extra a month for me which is no big deal. I run the 8120 at 4.6Ghz 24/7 and at 5Ghz for gaming. $4 a month extra is no big deal to me and really isn't anything to talk about when it comes do comparing chips.

Theres a normalized version of that graph floating around this very thread. BD is still way behind. even with an extra 10% it would still be 30% slower.

Amd was quoting only the wins over SB before launch, and they called shenanigans (multiple sources, multiple occasions) on anyone who reported that performance was low. So AMD was indeed trying to convince everyone it was super win.

To consume even more power? For the record Bulldozer was never intended to be a gaming CPU, its purpose is for server CPU. And for those who are building a server they sure care a LOT about power consumption. They want the best performance/power consumption ratio.

Oh, and why don't you post some benchmarks?

In this respect it actually fares decently, as once vcore and clocks drop to a certain point GloFo's 32nm process polishes up nicely. Its main problem is that when scaling to higher speeds its power consumption goes up very quickly.

Is BD on FD or PD SOI at 32nm? Cant find any info on either, and FD-SOI isnt until 22nm. I will guess its neither in this case.
