The Larrabee many-core visual computing architecture uses multiple in-order x86 cores augmented by wide vector processor units, together with some fixed-function logic. This increases the architecture's programmability as compared to standard GPUs. The article describes the Larrabee architecture, a software renderer optimized for it, and other highly parallel applications. The article analyzes performance through scalability studies based on real-world workloads.
