You are correct, the intel system would allow the 7970s to be overclocked more.

I just find it interesting that so many people talk about price without ever thinking about how much they are paying, on a daily basis, to use their computer.

Also, can we please not blindly say TH is biased. Saying they are Nvidia biased when they are using AMD GPU's seems a little foolish, no? Say what you don't like about the article, but it doesn't help anyone to blindly state that something is biased.

There, I fixed the power usage graph, to give a better idea of actual power usage.



Notice how Piledriver can use less than the stock Turbo Voltage when overclocking. Thus, it can actually run cooler and with less power at a higher frequency.

Given the comparison. If I were to have an overclocked 8350 completely pegged at 100% usage folding for an entire month, the price difference would be ~$1.50 @ 8c per kW/h. That alone is within margin of fluctuation of heat and lighting usage.

On top of that, normal usage for me is far from 100% pegged. The power consumption argument is pretty idiotic and the people using it are either uninformed on the subject or drawing at straws.

The quest for efficient chips is not to save the plebeians from ungodly electric bills. It is to extend battery life of mobile devices and scale up that performance into a traditional desktop power envelope.

Mind explaining how you got that 640 W number?

Here is what the source said about power consumption:
Quote:
The FX-8350's stock power consumption doesn't look too terrible compared to Intel's, even though it's indeed higher. But we don't get the whole story from this chart, either. We didn't see AMD's chip running at its rated 4 GHz when it was under duress at stock settings. Rather, it dropped both its multiplier and voltage level under an eight-thread Prime95 workload to stay within its rated power envelope. Throttling artificially curbs the CPU's power consumption, and the big increases we see when the Vishera-based processor is overclocked come from fixed multiplier and voltage settings.

At the same time, games don't really utilize the FX-8350's ability to handle eight threads concurrently, and consequently never seem to trigger the same throttling mechanism. Also interesting is that the FX-8350, at its stock voltage setting, often exceeds the 1.35 V we set manually for overclocking. That explains why system power consumption doesn't change much between the stock and overclocked GPU load tests.

Wish they would've compared to a similarly priced CPU from Intel.

Regardless, it would come up that price/performance and perf/watt the Intel i5s and i7s slaughter everything AMD has to offer. Sad really, I prefer AMD. But, it's just plain silly to waste money on a sub-par platform.

In the performance sector, AMD is soudly beat, even on price/performance. In the "consumer" market they have some neat offerings. Sure even an i3 will beat an A8 APU, but an i3 doesn't have a half-decent GPU on board either.

The review seems honest, though the value metric at the end is stupid. They can't say that the "average" person buys THESE things when they update their rig. Most desktop builders actually upgrade piece by piece, so they should be basing the value segment off JUST the CPU+Mobo. You can't say "here are the bare essentials... but lets also throw in something ($800 of GPU's) that totally skews the data away from what parts we're actually talking about."

BF3 and BC2 have shown that multi-threaded FPS games are the future. As that becomes more true, we will see more and more performance out of complex multi-core CPU's like the FX-8350.

A point I have been saying forever now, yet they seem to think being better at single to dual threaded apps is the future. rolleyes.gif

Games will now be coded for a AMD jaguar 8 Core CPU so you can take it as fact that games will most definitely be coded for more cores than strong single threaded.
