More details are available concerning the successor of Sun's UltraSPARC T1 (Niagara) processor. The Rock processor - due out in 2008 - will have four cores or 16 cores, depending on how you slice the product. By that, we mean that Sun has divided the Rock CPU into four, separate cores each with four processing engines. Each core also has four FGUs (floating point/graphics units). Each processing engine will be able to crank two threads giving you - 4x4x2 - 32 threads per chip.
