Sun Cancels UltraSPARC IIIi+
Doctor Memory writes "El Reg is reporting that Sun has finally come clean and admitted that they have killed the UltraSPARC IIIi+ chip. According to John Fowler, Sun's server chief, 'We canceled it last fiscal year to focus on the ramp (up) of UltraSPARC IV+, Niagara and Niagara 2.' Sun has had great success with its new Niagara line, and with it's line of AMD-based systems."
I think that Sun UltraSPARC IV can replace UltraSPARC III smoothly (they share the same socket, Sun can provide help doing this, c...) According to: http://www.sun.com/processors/UltraSPARC-IV/index. xml
"Executing on Sun's Throughput Computing strategy, the dual-thread UltraSPARC IV processor marks the first milestone in Sun's Chip Multithreading (CMT) roadmap (...) It protects customers' investments through 100 percent application binary compatibility, and can provide an upgrade path for current UltraSPARC III processor-based systems "
It's like replacing an Athlon Socket AM2 Single Core with a Dual Core (I think...)
