We know very little about the upcoming iterations of the Xbox console apart from the fact that there will be a traditional as well as a cloud streaming-only version. A rumor is now doing the rounds that the streaming-only SKU will be powered by a semi-custom AMD Picasso APU. The exact specifications are still not available but this APU is expected to provide hardware accelerated deep learning for Project xCloud that allows for real-time AI predictions of player actions and thereby, helps in reducing latency while streaming.
