All eyes are on AMD this year as the PC world awaits the release of their new CPU microarchitecture, codename Zen. The anticipation is understandable as the Bulldozer core is nearly five years old, with only slight improvements in the Piledriver and Steamroller revisions during the interim, while Intel surged ahead with multiple updated CPU iterations. Last month, we received a taste of things to come in the form of the Wraith cooler, Zen's surprisingly competent beefed up stock cooling solution released in advance in a limited capacity.

Now we get to sample another morsel in the form of new FM2+ processors before the main course later in Q4. Having fallen far behind at the high-end, the budget segment of the CPU market has become AMD's primary battleground. Here they offer some compelling weapons, including integrated graphics rivaling what Intel offers on their expensive flagships, old school Athlons without graphics for those who don't need them, quad core CPUs at much lower price-points, and base frequency overclocking and unlocked multipliers on numerous parts, not just the premium ones. Even the motherboards are more affordable, bringing even more value to the table.

AMD's current APU lineup is sizable, with eight quad core 7xxx models now existence, separated into A10 and A8 models based on their GPU hardware, with A10 featuring more stronger integrated graphics with more compute units and stream processors. The differentiation doesn't stop there though as their is a wide range of GPU and CPU frequencies, 95W and 65W thermal envelopes, and locked/unlocked multipliers to consider. The latest two releases are the fastest 95W and 65W chips in their updated catalog, though they're based on the same 28nm Kaveri/GCN technology as the rest of the 7xxx series. The A10-7890K's CPU clock speed has a 5% advantage over the A10-7870K but it sports a US$160 MSRP, coming close to Intel Core i5 pricing. Our APU sample, the A10-7860K with its US$118 MSRP will probably be a more popular choice. It's positioned it to usurp the A10-7800 as the A10-7860K is equipped with slightly higher CPU/GPU speeds and an unlocked multiplier for just $8 more.

Until recently, the graphics-free Athlon X4 family was stuck with 32 nm Richlands featuring older Piledriver CPU cores but they've now been retired. Replacing them is the X4 8xx series which is somewhat late to the party, finally bringing Kaveri/Steamroller to the Athlon series. The most interesting SKU is actually the bottom-of-the-rung X4 845, a new Carrizo part which is essentially Kaveri paired with AMD's latest Excavator CPU cores which focus on efficiency. We'll be testing the flagship X4 880K, which operates at 4.0~4.2 GHz with a 95W TDP, and can be had for the low MSRP price of US$95.

The A10-7860K ships in familiar retail packaging though the stock cooling unit has been upgraded with a single heatpipe design and a distinctive 80 mm red fan; it's the updated heatsink for new 65W APUs moving forward. The Athlon X4 880K comes in a larger plain box to accommodate a "near-silent 125W thermal solution." It's essentially the Wraith cooler without the bothersome LED shroud that weakens its acoustic performance, so no loss there. As we determined in our Wraith review, the more substantial heatsink is fairly effective and can take the place of a mid-range aftermarket cooler, though it doesn't have a very pleasant sound.
