How We Test
I compare all three variations of the Munchkin in the following benchmark graphs. The stock Intel numbers from earlier this week are used as the 100 percent baseline that everything else will compared to. The main question today is if an 860K can be overclocked to match or beat an i3-4170, if not in actual performance, then at least in performance value. However, the latter is somewhat a moot point since this build is $14 more expensive than the Intel build.

Synthetics
The new AMD build ties the Intel system in terms of 3DMark graphics, but falls a little short in the physics and combined scores. The tied storage score in PCMark is expected since they both use the exact same SSD, but everywhere else the new AMD build falls behind. It thoroughly beats the Original in every facet, however.
The improved cooling makes its first mark as the 860K extends its lead significantly in the Dhrystone section. But though the new AMD improves over the Original's score yet again, it still can't catch the i3 in the rest of the Sandra suite. The original retains an advantage over the new AMD in the crypto department thanks to its stronger memory bandwidth abilities.
Gaming
We see some interesting things in the gaming section as the new AMD actually loses to the Original in more than a few places. While a few FPS one way or the other can simply come down to variations in GPU temp at the time, these are consistent losses for the new AMD across many games. My best guess of culprit is memory bandwidth again. There's also a trend of the new AMD trailing the Original at 4800x900, particularly at the lower detail settings. I'm not sure what's causing this either, as 5760x1080 results are more in line with what we expect.
The new AMD build experienced some crashes with the DDR3-2133 settings and had to be run at 1866 for the Arma runs. This hit me as odd since 2133 was perfectly stable for four hours of Prime95 and 3DS Max renderings. As I do the gaming benches last, I didn't have time to redo the whole suite at 1866 settings. As it is, the new AMD loses just slightly to the Original, though most results are a tie. Arma certainly favors Intel's microarchitecture.
If you thought the Battlefield 4 results were similar a few days ago, they become almost identical here. The Intel build has a lead at lower details and most resolutions, but once you hit 1080p and Ultra details, you can't tell one machine apart from the next when playing.
The new AMD build is actually penalized when overclocked in Far Cry 3. My best guess is the sketchy memory behavior that the motherboard exhibited in many other places. It's more apparent at lower detail settings. Cranking it up to ultra levels things out a little more, though the new AMD still trails by a small margin; the i3 is still clearly in the lead.
At stock clocks, the AMD rig shows clear benefit over the Original in Grid. This lead becomes even larger when playing across three displays. Neither AMD build can come close to the Intel version, though.
Applications
The new AMD build just got soundly thrashed in the last benchmarks. Is there any hope for it? Absolutely. Just check out the improvements in the real-world application benchmarks.
Even overclocked, the 860K can't match the i3 in efficiency for the single-threaded iTunes and Lame benchmarks. But let it bring all four cores to bear and you can see some magic. At the stock 4.0GHz turbo, the 860K is already beating the i3. Boost those cores to 4.3GHz and it takes a 30 second lead. Shaving seven seconds off the TotalCode benchmark is impressive, too.
The new AMD splits the Adobe suite with victories in Photoshop and Premiere. After Effects loves memory, and Photoshop with OpenCL loves Intel's efficiency, so the new AMD can't keep up there.
Once again, the new AMD splits the wins in the productivity group by taking ABBYY and an impressive win in 3DS Max. Cutting two minutes off the Original's score is impressive. It loses a close match in Blender, but Acrobat, as a single-threaded test, is far out of reach.
Though the new AMD build makes up a lot of ground in the compression suite, the i3 retains its crown.
While the 860K didn't win quite half of the benches here, it looks a lot more impressive than you would be led to believe going just by the game and synthetic tests alone.
Power & Temperature
We always knew the AMD wouldn't have a chance beating Intel in power draw tests. However, I was able to cut more than 20W off the CPU usage while boosting sustained clockrates. Take the wins where you can find them, right? As for the strange CPU idle temps, I blame Gigabyte for that. Gigabyte's monitoring software said my CPU was idling below ambient. Chris reported his Gigabyte motherboard was saying the same. Thomas pointed out that since most thermal diodes read backwards from critical temps, the colder they are, the more room for error.
Overall Performance & Efficiency
With the stock Intel build set as the baseline, we can see clearly how the new AMD stacks up. While it scores a small victory in the Productivity category, everywhere else it falls well short of the Intel build. It's even a few percentage points behind the Original in gaming.
Once again, we know the AMD runs on a lot more power. There's no way it can win an efficiency award. However, it is 12 percent more efficient than the Original.
System Value
I'm using adjusted prices for what these components would've cost last quarter, the same I did earlier this week. While I only paid $912 for the whole system right now, it would've cost $946 and change three months ago.
The final verdict is that no, the new AMD does not bring as much performance value to the table as the Intel build. Though it makes a nice six percent value jump from stock to overclocked, it's still 10 percent behind the Intel. While the Original seems to overtake the new AMD in value when you don't count the OS cost, remember that doesn't count the 1TB storage drive. Stripping it down to just the platform parts shows a better picture of actual user experience and value.
Gaming Value
I'm almost sad to bring this up, but each Munchkin was meant to be a gaming build, and that means the new AMD has to take its medicine. Often scoring below the Original while costing more severely hurts the new AMD's value.
Final Thoughts
So how do I rate this new AMD build? Mixed. This third revision has been a sick cycle carousel that's seen both desk pounding cries of agony and adulation. It's supposed to be a gaming machine, but it usually performed worse than the last two iterations. That looks bad, and is a black eye for me. Hey, I'll take my licks. The bright spot here is the huge improvement in productivity and professional applications. When not outright winning, the 860K was usually close behind the i3. I wasn't sure it would win more than a handful of benchmarks, but it came close to taking half of them. But I have to temper my excitement about that because overall it was only one percent better — that's almost margin of error level. Perhaps with a better motherboard I wouldn't have been hit by the memory performance glitches.
But that comes to the heart of the matter: the uncertainty of overclocking. Can an 860K be overclocked to the point that it beats an i3? Yes it can. But that comes with a lot of caveats. First, you need a chip that's capable of hitting at least 4.3GHz (preferably 4.4GHz). That's not a given. Second, you need a good motherboard that can not only get the CPU up to those clocks, but that can get your RAM to DDR3-2400 speeds (or better) in order to match the bandwidth that the i3 gets at DDR3-1600. And unless you want to spend more money on less performance, you need to find all this, as well as a good CPU cooler, for about $200. It's certainly not impossible, but it's definitely not simple.
I understand the tinkering mentality. Until you know how to take something apart and put it back together better than it was, you don't feel like you have fully mastered something. We love tweaking our computers and squeezing every last drop of performance out of them. That's all we want. No more, no less. But at what point are we just wasting time?
While you can tweak an 860K to approach the performance of an i3, how much extra time and effort does it take? Not only in tracking down the exact parts you need, but also the time, effort and frustration of finding the optimum overclock settings. In the end, you only get single-digit performance gains. Can you put a money value on your time? If so, factor that into your performance value calculations.
I don't mean to discourage anyone here. If you want to push your FM2 platform to the limit, more power to you. And please, share your success stories in the comments. I love reading them. I'm just not the type of person that enjoys masochistic puzzles.
