AMD Athlon II X4 645 in the labs - Power-Consumption

Written by Eliot Kucharik

Review: Slight speed pump for the Athlons

 

Power-Consumption:

With the new steppings, AMD went the right path to decrease power-consumption considerable and fight Intel nearly on par.

With a little less VCore on default, it does help the CPU to achieve a better performance per Watt also due to the higher clock. Not all CPUs/Chipsets have onboard graphics, so especially the i5-750 runs with our HD4850.

Of course the more you overclock with voltage increase the worse the efficiency will be.

Cannot say i fully understood a single page of this review.

speed bump, actually

Not that its' relayted to this article, but it's still fully any people trust or benchmarks with Entech/FutureMark benhcmarks. They haven't understood hardware in years and it truly shows here at 3DMark.

As for article I honestly think the 5 pages shows all needed for the released new core.

erm..speed...Pump? what is that?

Before we render a conclusion, let's have a look at the overall benchmark results

O_O...oh thank you for looking at benches before the conclusion

optimised on AMD platform? erm..if you talkin bout GPU its ok but cpu..

Not sure about Intel, but whenever AMD does one of these across-the-line speed bumps, the new models replace the slower ones, in effect making the CPU at any price point faster.

Does the world really need a million different AMD processors with only slightly different clock speeds?

We now have the whole spectrum between 2,7 and 3,6 GHz covered with 0,1GHz steps.

Why would I go for a 3,4GHz CPU when I can get a 3,5GHz for (almost) the same price? :o

AMD CPU and GPU is the cheap and slow poormans PC parts,discount parts.

that is a seriously poor overclocking sample you have there. I am not trying to brag i am just wondering if you tried everything to get it working at higher frequences. I needed to increase many voltages to get mine stable. I bought a X4 620 (2.8GHz) and run every voltage at stock and get 3.6GHz out of it. I had so got it stable above 4GHz but there was a lot heat to deal with and not worth it because of the noise.

Did you try dropping the multiplier and running the FSB really high? I mine goes to 320MHz without a problem.

A potent graphics-card will always be more crucial for good framerates then a faster CPU.



Maybe a couple of years ago, but as broken as games are nowadays, I highly doubt it.

Once you buy AMD, you don't go back... to AMD.. ever again
