The following chart reflects power consumption throughout our benchmark suite, which gets logged every two seconds. The long, straight section at the end represents 30 minutes of idle time inserted by our automated script to better reflect actual use when we calculate averages.

Our comparison is principally between Intel’s Pentium G3258 and AMD’s Athlon X4 750K. We’ve seen how both CPUs size up in the performance metrics, and now we get a better idea of how much power they pull down along the way.
All four configurations spike into similar territory. Three settle around the same idle power, while one (the stock Pentium G3258) idles quite a bit higher. Interestingly, this is the same behavior observed from Intel’s Core i7-4790K on MSI’s Z97 Gaming 7. Since the Core i7-4770K was fine, I’m inclined to believe there’s some firmware work to do for Intel’s newest multiplier-unlocked models.
That long stretch in the middle, which is our Visual Studio test, best represents a CPU-heavy task with no graphics intervention. It shows the stock Pentium using the least power, followed by the overclocked Pentium, the stock Athlon, and the overclocked Athlon, just as each CPU’s TDP would indicate.
Based on the length of the lines, we also see that the stock Pentium G3258 is the slowest entry, followed by the stock Athlon X4 750K. You can’t really see it behind the other lines, but the overclocked Pentium wraps up first.

When you average out power consumption across the entire line graph, you get the above chart. The stock Pentium G3258 should probably be quite a bit lower. However, because there appears to be an issue with it idling at stock clock rates, 30 minutes is spent more than 20 W too high.
At any rate, the overclocked Pentium certainly uses more power in its quest, due to the higher voltage and clock rate. But we also know it finishes the tasks we throw at it faster. Meanwhile, overclocking AMD’s Athlon X4 750K doesn’t have a profound impact on average power use at all. That likely indicates good things for efficiency.

A glance at the line graph gave us this same information, but we more clearly see the finishing order of our entire suite. Intel’s Pentium G3258 starts as the slowest contender and, through overclocking, ends up fastest.

Multiplying power consumption and run duration gives us a Wh rating for each system.
Intel’s Pentium G3258 starts off using little power. However, mediocre performance and a poor idle combine to delivery lackluster efficiency. Only the stock Athlon X4 750K is worse. Its performance is better than the Pentium’s, but a 100 W TDP hurts the equation.
Overclocking to 4.3 GHz helps the Athlon improve its performance even more without affecting power consumption much. But the Pentium can’t be stopped. Average power use jumps 10 W (12%), while the benchmark suite finishes 23% quicker. The result is a first-place finish in efficiency.

Because of course buying a pentium G and fitting it with a 150USD board and 50USD cooler does not make sens by itself ,but you have a 100% future-compatible system that can be upgraded very very easily...
No, sorry. That is not true. Check this article:
http://www.tomshardware.com/reviews/ivy-bridge-wolfdale-yorkfield-comparison,3487-10.html
You should overclock your Q9550 to get performance that barely comes close to an ivy-bridge I3 on games and lightly threaded workloads (and it gets stomped by any i5 on any workload)... I personally have an OC'd QX9650 and am not even close. I believe if I change to that Pentium G, and overclock it as well, that would still be an upgrade...

Yeah that would be better unless Intel decides to let o/c on Pentium with other chipsets like H97.
Leaked BIOS Enables Pentium Anniversary Edition OC on Some MSI H97 Boards
MSI H97 PC MATE ATX LGA1150 Motherboard $88.99
So if this happens and intel decide to let even lower mobo chipsets to do o/c only for pentiums it would be nice to pair $60 mobo, $75 CPU and a $25-30 CM 212 EVO or plus, to a total of ~$160 for a o/c ready system.

As you say, the price difference is negligible. The performance difference is also fairly small, and both platforms leave lots of headroom for future upgrades. I am under the impression that any motherboard that can house this new Pentium can also run a blazing-fast i7. The article, unfortunately, doesn't mention that the AMD solution can't even run a FX chip. For someone looking to just get into an inexpensive PC with an eye towards future upgrades, the Intel solution is dramatically more attractive.
Compelling CPU, unfortunately your still stuck with buying a mildly overpriced Z-series board.
Now if this CPU had Iris or Iris Pro, then it would be MUCH MUCH more compelling.
Anyway I can see this being a good buy for an enthusiast that isn't quite making it to get an I5 or I7 at their price point but needs a machine performing decently NOW and wants to overclock, he can then upgrade to and I7 or I5 at a later date.

The point is rather moot as you probably wouldn't upgrade from a Kaveri-based APU to a Piledriver-based CPU, and FX in its current form is dead anyway.
> Could get a Q9550 for that price on Ebay ...
An i7 870 on P55 would be a better buy than a Q9550. 870s dropped below
50 UKP on ebay UK this week. Never mind S775, my 870/P55 setup was faster
than a friend's X58/930 system for gaming (lower latency with P55, and some
boards do have x16/x16 CF/SLI).
Ian.
I would expect a round of price drops from AMD over this; otherwise they're done in the gaming market.
