Console manufacturers are notoriously shy at providing specific hardware details to the general public.  Therefore, the following information is not guaranteed to be 100% accurate and subject to change without notice - much of the finer points have been gleaned through Internet-based research, as well as suggestions from other people, and may be based on indirect evidence or rumours.

 Notes
   1 - The transistor count includes additional embedded devices such as audio and I/O processors.
   2 - Tile-based rendering graphics chip, thus depth values are always at this level.  Value is FP, not integer.
   3 - The Xbox 360 has a single CPU that contains 3 PowerPC-like cores that can each handle two threads.
   4 - The frame buffer memory is not on the same die as the Xenos chip; both dies are on the same module.  The eDRAM also contains the ROP circuitry.
   5 - GPU to eDRAM circuitry is 30+GB/sec; eDRAM ROPs to DRAM bandwidth is 25 GB/sec.
   6 - 232M for GPU die, 105M for eDRAM die.
   7 - The Saturn consists of multiple processors, each of which have specific tasks.  Two SH2s are used for main processing, along with two VDPs, and several DSPs.
   8 - The main memory could be expanded by a further 4MiB to 8 in total.
   9 - The PPE unit of the Cell has 64KiB of L1 cache and 512KiB of L2 cache; each SPE has 256KiB non-cache local memory.
  10 - This value refers to the FlexIO interface; other bus values are lower.
  11 - The EE chip contains three small, L1-like, caches: 16KiB instruction, 8KiB data, 16KiB scratchpad.
  12 - The pixel output rate is for zero textures applied; with 1 texture, the rate is 8 pixels per clock; 2 textures = 4 pixels per clock and so on.
 PlayStation 2 Process Scales
  At launch, the EE and GS were both constructed at 250 nm; over the years, Sony has used smaller sizes to improve costs.  Currently, both the EE and GS reside in the same 90nm chip - approximately 6  times smaller, in surface area, than the original chips combined
 Transform Rate (TR)
  The max polygons per second values labelled with a TR tag refer to the maximum rate at which vertices can be transformed (moved, rotated, scaled, etc).  The actual polygon throughput to the rasterizer will   be significantly lower than this.  Values without this tag are given without any knowledge of what conditions the rate refers to.
