SME5410MCZ-270
270 MHz CPU, 256 Kbyte E-cache, UPA, 66 MHz PCI
UltraSPARC-IIi CPU Module
July 1998
Sun Microsystems, Inc
TECHNICAL CAPABILITIES
All performance specications are for a 270 MHz processor, with 256 Kbyte 2-2-2 mode E-cache.
One of the features of UltraSPARC-IIi is the superior performance of its integrated I/O, DRAM and
UPA64S interfaces:
Note:
DRAM bandwidth is one-third to one-quarter greater than these numbers, since there is an initial
DRAM read of the data locations that are used for store operations.
