CPU notes

^source

X86

Intel Pentium III

• 3400DMIPS
  • 3.4DMIPS/Mhz
  • 400Mhz-1Ghz

AMD64

Modern Intel i5/i7

• 29000DMIPS
  • ~10DMIPS/Mhz
  • ~2.9Ghz?

MIPS

Ingenic XBurst1

• performance?
  • uses MIPS32 rev2 + SIMD2 instruction sets
  • MIPS32 24K also uses an 8-stage pipeline ^source
    • so ~1.6DMIPS/Mhz?
• L1 cache
  • 16K instruction
  • 16K data
• L2 cache
  • 256K
  • TODO does GPU share this?

MIPS 24K

• 1.6DMIPS/Mhz

MIPS P6600

^source

• 5250DMIPS at 1.5Ghz
  • 3.5DMIPS/Mhz
  • 1Ghz-2Ghz

Sony Allegrex

^{source source}

• 533DMIPS?
  • uses MIPS32 rev2 instruction set
  • maybe a R4000, 4KE, or 24K?
    • 1.6DMIPS/Mhz?
      • might be more with the crazy-wide bus
        • although, the GPU probably uses that too
          • CPU has its own eDRAM which suggests that's a scratchpad to work out of when the bus is slammed
            • the only other peripherals capable of slamming the bus are the "media CPU" and GPU
  • 333Mhz
• "2.6GB/s bus bandwidth"
  • 128bit wide
  • 166Mhz
  • makes sense (2600MB/s ~= (128bit * 166Mhz) / 8bit/byte)
• no MMU
