AMD FX-8370E At 3.5 GHz
The first step in our exploration is increasing the FX-8370E’s frequency by just 200 MHz. All of the basic BIOS settings are left alone otherwise.
Core Voltage
The core voltage curve is now smooth. Also, it drops to 1.14 V with a Vcore setting of 1.1850 V manually set in the firmware.
Power Consumption
Power draw measured directly from the PSU is 78 W, representing a meager 3 W increase. This proves two things. First, the motherboard’s automatic regulation isn't well-optimized, since all other settings are the same as they were during our stock 3.3 GHz testing. Second, this CPU is a lot more efficient than its predecessors.
Temperatures
The temperatures don’t rise in spite of the higher clock frequency, which is probably due to the lower core voltage.
The AMD FX-8370E remains easy to cool at 3.5 GHz. A sub-$20 cooler should suffice.
AMD FX-8370E At 4.0 GHz
Let’s take a big step up and push the FX-8370E all the way to an even 4.0 GHz.
Core Voltage (Vcore)
An average of 1.17 V is good enough for stable operation, and we had to change the BIOS setting to 1.2125 V to achieve it. The curve continues to look very smooth.
Power Consumption
We measure 90 W at the appropriate rail, which should work out to somewhere between 80 and 82 W for the CPU alone, once the losses due to the voltage regulator are subtracted. Nice!
Temperatures
The thermal readings remain in a range that could be handled by AMD's reference cooler without forcing its fan to spin uncomfortably fast. Our third-party cooler's heat pipe only climbs to 35 degrees Celsius.
The FX-8370E can be overclocked stably with a minor voltage increase. It stays well below its official TDP of 95 W, even at 4 GHz. If relatively mainstream performance is acceptable, you can get it from this economical CPU that's easy to keep cool. Still, we can't ignore the fact that lower power consumption is enabled by a reduced clock rate compared to AMD's higher-end models.






If you pre-suppose that your sample is tainted why bother to do the testing and the article in the first place. Perhaps this is a case where your should purchase the product of the shelf in order to better serve your readers.
I think we all get it Vishera isn't exactly wonderful in single core operations, but:
A) I have yet to see any software which requires A LOT of single core power, it's 2014, if something is still single-core, it probably doesn't need all that power or il old enough to make even Vishera good at it.
B) You are comparing a 2012 architecture to a 4790K, It's like comparing Pentium 4 to a Pentium G3258.

8150, 8320, 8230e, 8350, 8370e.
That would demonstrate the improvements of Vishera over Bulldozer, as well as any improvements offered by binning.
1) almost every vendor does this, cpus, graphics, ect..
2) the chip they received is exactly what you get when you buy it off the shelf, however every cpu/gpu ect varies by a small amount. The vendors simply make sure that review sites get the top end of that group. In all honesty we are probably talking 3% performance from the majority at most.
My 8320 will happily run 3.5/3.6ghz @ 1.15v as long as turbo core is disabled.
I will probably get the 8320E for my office computer during Black Friday. $140 is the price right now but I prefer $125 or less for an AMD CPU.
Far too many people forget the whole cost of OCing a chip. Sure, a 4.5 83XX can slightly beat a stock i5, but at what cost? The 6300 is a far more compelling CPU for tweakers. If you're lucky on a few sales, you can get the chip, cooler, and mboard for the same $200. And as pointed out here, unless you're pairing it with a top-shelf GPU, you won't see any gaming benefits with a pricier platform.
This is AMD's latest offering. The Haswell refresh is Intel's latest offering. Whatever the products' pedigrees, why shouldn't the two latest SKUs be compared?
AMD is embarrassing itself with these "new" releases. It is quite sad. I wonder how many more years they will milk "Piledriver"?
agreed, this cpu need new (limited) mobo to operate.. this making it's a minus point...
anyways we need to keep advocating good balanced built more often..
I see lot's of people keep waste money in one (op) part to only be limited by another parts in his system...
(the true potential of the system is nowhere to be seen)

Agreed, too many people, and some that I personally know will throw a high end K chip in their rig and match it with a $120 GPU while not wanting to overclock said CPU, and then get mad because they can't max out new titles. Recently, a friend's brand new i7 rig was out ran by my overclocked FX rig in a bet on the Metro LL benchmark due to his GTX 650 GPU vs my heavily overclocked R9 280X
However, it seems that AMD won't be making any new CPU architectures until 2016. I'm doubtful that AMD will manage to push the clock any further in the near-future, though 5 GHz is possible. A 200W part will make your PC a space heater.
For the 2016 build, there's a chance that AMD may be revamping the CPU drastically, but there's also the chance that AMD will just give up. The third alternative is that they will release a CPU update for game consoles.
I'm also doubtful about the hybrid x86/ARM chip they want to make. In theory, it's sound, but I'm thinking of the complications from programming the thing, plus the potential for bugs.
