Power consumption with Einstein@Home: 128W

Your completion times are better than I would have expected from a Phenom. Are you doing anything special with it to increase performance?

he even says it's only at 800MHz, not even 1066. He states 128W while the only Phenoms I can find (including 9600 Black) are 95 W. Perhaps an OC????

Look at Akosf's results on

Look at Akosf's results on his Q6600 rig and compare that to other Q6600s here, now thats FAST, he got some nice handcoded apps going i think. Comparing core for core Phenom will perform only slightly better than a similar clocked AMD X2.

I guess power consumption would be for the entire system. As for doing something special to increase performance, I guess Akos is applying some magic to the app as he did for his Intel Quad Core, see the TOP 10 computer list :-)

My Phenom and Core 2 Quad run a simple SSE optimized code.

I measured 128W for the entire computer without monitor.
(power supply, motherboard, RAMs, CPU, fans, HDD)

I don't have suitable equipment to measure only the CPU.

I'm terrible sorry, but Phenom offers poor performance.
Phenom is a bigger disappointment than I expected on the preliminary infos. :(

Yeah, that seems to be the general consensus. I hope that AMD will finally get the bugs worked out of it, and increase its performance, though. (Intel needs viable competition.)

Kinda funny article about

Kinda funny article about AMDs upcoming Phenom X2/X3 processors,
http://www.overclockers.com/tips01271/

They will release tri-core of the current Phenom stepping, the B2, so TLB errata is included at no additional charge. These are supposed to be quadcores with one bad core disabled:

To add insult to injury, these won't be available until March.
Geez, it's one thing to be delayed getting fully-functional
pieces out, but delays in getting broken ones out?

---

If you have a bunch of broken ones now, you might as well put them out now.
If you don't have enough of those and have to make unbroken tricores, why
would you want to make a bunch of B2 tricores?

Hmmm... I'm thinking of

Hmmm...

I'm thinking of building a new system with a 9600 Phenom.

On one hand, there is the TLB bug. But that seems to be contained and I haven't heard even one report of it being hit. The TLB fix, on the other hand, does significant performance damage according to the numerous reviews I have read. Poor WinRAR still isn't walking straight!

Then again, Intel's offering in that performance range is the Q6600, and it appears that I'd have to spend another hundred dollars between the CPU and motherboard to get the equivalent offering.

Plus there is the overclocking issue, which is something I like to do. It appears that the Q6600 has the leading edge over the Phenom 9600 [black too] when you take into account the wild variation in what you can get out of a Phenom.

But then again, I'm building a /small/ system with a uATX board. I can't OC too much on either side of the aisle because I don't know how well my uATX case will fare when I have a quad core CPU mixed in with an 8800 GTS, three harddrives, and an optical drive.

Methinks I'll go with the AMD Phenom. Folks have had release & engineering samples for months now, and the basic consensus seems to be disappointment from high expectations plus frustration with TLB issues. I can live with that.

I suggest Core2 for crunching Einstein@Home.
