At CES 2011, they gave us a sneak peek into the Embedded G-Series platform based on Brazos. AMD has increased performance and features in every generation while bringing down the power, area and price barriers for x86 in the embedded market.
In the meantime, solutions like what we are seeing from AMD today integrate premium graphics capabilities within power envelops similar to what x86 used to consume in the previous generation—so you get CPU+GPU instead of just a CPU. RISC based embedded solutions may still be winning on the power front; however, for applications where slightly higher power consumption is not a concern, the x86 threat from the AMD embedded G-Series platform can become a cause for concern. MIPS is usually popular in such applications (set top boxes, digital signage etc.) and they will be facing credible opposition with AMD's integrated graphics capabilities.
