* The Redsparc actually has a variable speed clock, meaning different operations can take different amounts of time to complete. 4 Hz is just the average for most operations.

** The Redsparc uses command blocks for RAM access. Being that command blocks can handle 32 bit integers, the Redsparc has access to a theoretical 4GB of memory. In practice, trying to use more than a few megabytes of memory will cause Minecraft to crash. So the practical limit would be more like 16MB.
