Sun Microsystems is expected to revamp its core Unix server line on Tuesday with the debut of its high-end UltraSparc IV+ processor. The big UltraSparc IV+ improvement is the inclusion of 2MB of built-in high-speed cache memory where UltraSparc IV had none. The initial clock speed of the dual-core chip is expected to be 1.5GHz.

The article is a little misleading. The L2 cache was off-chip in the US-IV, but there was 8M/core (16M/socket). The new chip will have on-chip 2M L2 cache, as 32M off-chip.
Sun has also shrunk the die from 130nm to 90nm, which is what has allowed them to add the on-chip cache.
