Cell Broadband Engine

The Cell CPU has one 3.2Ghz PPE (Power Processor Element) with two threads and eight 3.2Ghz SPE (Synergistic Processing Elements).

The PPE is a general purpose CPU, while the eight SPE are geared towards processing data in parallel. One SPE is disabled to increase yield, so the PS3 can have at most 9 threads runnings at the same time (2 from PPE and 7 from SPE). Note that one SPE is reserved for the hypervisor, so PS3 programs can take advantage of 8 threads. Both the PPE and SPE of the Cell are 64 bit, and manipulate data in Big Endian.

Specifications

  • 1 PPE (Power Processor Element)
    • 3.2Ghz
    • 64 bit, Big Endian
    • 2 threads (can run at same time)
    • L1 cache: 32kB data + 32kB instruction
    • L2 cache: 512kB
    • Memory bus width: 64bit (serial)
    • VMX (Altivec) instruction set support
    • Full IEEE-754 compliant
  • 8 SPE (Synergistic Processing Element)
    • 3.2Ghz
    • 64 bit, Big Endian
    • 1 SPE disabled to improve chip yield (see: Unlocking the 8th SPE)
    • 1 SPE dedicated for hypervisor security
    • 256kB local store per SPE
    • 128 registers per SPE
    • Dual Issue (Each SPE can execute 2 instructions per clock)
    • IEEE-754 compliant in double precision (single precision round-towards-zero instead of round-towards-even)

There is a lot of info about CELL/BE on the Cell Programming IBM page.


Serial Numbers @ SKU

The Cell was introduced at 90nm. Later, PS3 model numbers starting with CECHG uses the 65nm version, while the PS3 Slim (CECH-20xx) used the 45nm version (See SKU Models and table below).

A sampling of the serial numbers by model number.
