If we were 2-3 years in the future, when many more applications were written to fully utilize the capabilities of SIMD arrays like the one found on the Llano APU, the A8-3850 would be an easy recommendation over the Core i3-2100. We are sorry to report though that it is still 2011 and the number of GPU-accelerated applications is still limited though not due to the push of NVIDIA and AMD. With the exceptions of some video processing apps and gaming, the GPU in the Llano will be under-utilized I fear and even in some of the areas AMD claims victories in (video playback, transcoding, etc), Intel is doing nearly as well or good enough to get by. AMD needs those must-have applications that utilize the GPU today."
