Abstract:
Methods and apparatus relating to Multi-Sample Anti-Aliasing (MSAA) memory bandwidth reduction for sparse sample per pixel utilization are described. In an embodiment, Multi-Sample Anti-Aliasing (MSAA) logic generates render subspan plane information based on data stored in a cacheline. One or more read operations to memory are suppressed based on a determination that the cacheline is in a clear state. Other embodiments are also disclosed and claimed.
