AMD's desktop CPU business has been neatly delineated into one high-end and one low-end platform for a few years now, with the AM3+ socket representing the former and FM2+ socket representing the latter since its launch two years ago. FM2+ accelerated processing units (APUs) offer a decent value proposition with integrated graphics that surpass many entry level discrete video cards, affordable quad core processors, and unlocked multipliers on many models to facilitate overclocking to stretch your dollar even further. Last month we examined two new chips, their fastest yet 65W APU, the A10-7860K, and the graphics-less 95W Athlon X4 880K, part of AMD's refreshed lineup for 2016.

Today, I'm going to take a look at their new flagship APU, the A10-7890K. With a higher TDP constraint, it sports CPU clock speeds of 4.1~4.3 GHz, 300~500 MHz faster than the 65W A10-7860K, and its integrated graphics is clocked 15% higher at a considerable 866 MHz to match the previous flagship A10-7870K. The most notable aspect of the A10-7890K isn't actually under the hood; its US$160 price-tag is a considerable jump from the A10-7870K compared to the rest of the APU family. This is a concern for a so-called budget processor as an extra $15 can net you a much higher level of performance in the form of a a Haswell-based Intel Core i5.

One aspect of the A10-7890K that may balance the scales somewhat is its stock cooling solution. It's one of the new AMD chips shipping with the vastly improved Wraith cooler, a substantially larger and more formidable heatsink/fan than what ships with their 65W SKUs. Our testing has determined that the Wraith has at least a 21°C advantage at equivalent noise levels over the smaller cooler, putting it in the same league as a small tower heatsink or a sizable down-blowing model. With an unlocked CPU multiplier and strong cooling out-of-the-box, AMD not only enables overclocking for the A10-7890K, it actively endorses it.
