'''Valhalla''' is a system-on-a-chip combination of the [[XCPU]] and [[GPU]] used in the [[Xbox 360]]. It is the successor to [[Loki (CPU)|Loki]] and [[Kronos (GPU)|Kronos]], and is manufactured on the 45nm process (except for the [[eDRAM]] daughter-die, which remains at 65nm). It contains an "emulated" FSB between the CPU and GPU areas of the die in order to remain compatible with the previous separate CPU and GPU. Valhalla also adds an [[IHS|Integrated Heat Spreader]].

Vejle (originally called Valhalla) is the first XCGPU and is used on the Trinity, Corona, Waitsburg, and Stingray motherboards. It is the successor to Loki CPU and Kronos GPU and is manufactured on the 45nm process (except for the eDRAM daughter-die, which still used Styx-65). Vejle adds an integrated heat spreader over the dies.
