A stock A8-3870K ships with its CPU set at 3GHz and the graphics core clocked at 800MHz. Our attempts to increase these weren't exactly stellar - it ramped straight up to 3.4GHz/800MHz, but any attempts to go further were unstable enough to be frustrating.
With more fine-tuning and a really good cooler, we've seen reports of much higher clockspeeds, but we're not overly sure it's ultimately worth it for the performance returns.
Plus, it's unlikely that motherboard manufacturers are going to get behind this platform with high end boards full of good, stable overclocking features – because potential purchasers just aren't going to spend the extra they'll cost to make.
Still, since the A8-3870K is already available for less than its non-tweakable predecessor, the A8-3850, the unlocked multiplier is more of a pleasant extra to have.
So even if our dream of using one to outperform a Core i7 isn't going to happen, the A8-3870K is still a great little chip.
Because it has four native cores it outperforms Core i3 in tasks like media rendering and so on, although Intel's computational engine is still superior in games – even if its graphics lags far behind.
For a workplace PC, then, the A8-3870K is an exceptional choice. It'll beat a similarly priced Core i3 system at everything.
It gets a bit more complicated if you're after a budget system that can game at 1080p – to use as a media centre, for example.
Even overclocked, the A8-3870K alone isn't an alternative to discrete graphics – although it does come very close if you're willing to sacrifice graphics quality. Battlefield 3, for example, is this far off being playable at 1920x1080 with low image quality settings.
Which are still bloody good looking.
Skyrim at similar settings runs like a dream.
If you're thinking of adding in a mid-range card like the HD 6870 or even something as powerful as an Nvidia GeForce GTX 560Ti, though, Intel just wins through – although it's a draw in CPU limited games like Shogun 2 and Skyrim.
AMD's architecture does have the curious disadvantage of performing slower in CPU benchmarks when discrete graphics are attached too.
But that leaves one feature that we haven't discussed yet which bring us down in AMD's favour.
That feature is Asymetrical Crossfire – the ability to use both the A8-3870K's graphics and a low power GPU, such as an AMD HD 6670, for a gaming experience that's capable of playing most games at 1080p with medium settings.
That's a hell of a thing in AMD's favour.
Enough that while it's not going to be our chip of choice for a workstation or enthusiast games rig, if you want a small, low cost PC which is capable of occasional games at console quality, it's a steal.
Where it comes into its own is as a flexible platform for a quad core office machine or a flexible and capable gamer with Asymmetric Crossfire.
The potential to overclock is a bonus, but really not enough by itself to make us favour this chip over any other quad core Llano.
Not the budget buster we hoped for, but further's our faith in AMD to make Fusion the low cost platform of choice.
