AMD recently released some new SKUs in their processor and APU line-up (announced Q1 2016). Basically you noticed three new models A10-7860K, A6-7470K, and an Athlon X4 845 APUs. All APUs obviously are based on existing architecture with tweaks mostly found in clock frequencies. That AMD Athlon X4 845 processor might have been released silently, but it is based on Carrizo architecture and is a quad core 3.5/3.8 (core/turbo) MHz processor with its 2MB cache is tagged with a TDP of just 65 Watt, and close to that wattage is it's price as well as these puppies only cost $69.99 USD which you can spot under SKU codes AD845XYBJCSBX and AD845XACKASBX. The processor can take DDR3-2133 MHz memory to get it a little more bite in memory bandwidth. The processors have four x86 cores cores each with a cache memory of 2 MB.

The Athlon X4 845 have DDR3-2133 supported memory controllers, and a TDP (thermal design power) of only 65 making these solutions close to idea for media computers, small servers, a net-top or two and hey, maybe even an excellent home grown NAS or file server as the chipset offers really fast SATA3 connectors as well. Just not for a HTPC as this processor does not have a integrated graphics.

This processor is not a 'K' model, hence overclocking isn't an option either. However at that price you could build a simple enough gaming PC for under 400 EURO. The AMD Athlon X4 845 is based on Carrizo architecture, known from AMDs mobile platform, the CPU cores are based on Excavator cores fabbed at 28nm.
