  7. AMD Opteron • 1.4-2.4GHz • L1 128KB L2 1MB • AMD64 technology instruction set extensions • 64-bit integer registers • Eight new 64-bit integer registers • Eight new 128-bit SSE/SSE2 registers • 55W~30W • $800.00

  8. Ultra SPARC IIi • 500MHz • L1 32KB L2 512KB • VIS Instruction Set • 64-bit SPARC V9 • CMOS 0.18 micron process • 6 layer AL metal • 13W • $1,400.00

  9. Ultra SPARC III • 1.0-1.2GHz • L1 100KB L2 8MB (ext) • 64-Bit SPARC architecture • VIS Instruction Set • 4-way superscalar • 14-stage non-stable pipeline • CMOS .13 micron process • 1368 pin flip-chip ceramic Land Grid Array (LGA) • 53W • $6,500.00

  10. Comparison

  11. Conclusion • Based on the specifications found for each processor, we conclude that the most convenient one for power applications is the Power PC G5.
