Very skeletal, but here are some Speedometer 4 figures for IIci-2 (50MHz DayStar PowerCache); IIci-1 (33MHz DayStar Turbo040 with and without FPU), and IIci-3 (40MHz Carrera040 not 'seen' by system, ie still running a 25MHz 030; and 40MHz Mobius Speedster 040). OS 7.6.1 throughout.

• IIci-3 (68030/68882 25MHz, although MicroMac Carrera040 was installed)
  CPU = 0.43
  Graphics = 0.36
  HDD = 2.22 (Quantum Fireball 2GB)
  Maths = 1.50
   
  IIci-2 (68030/68882 50MHz DayStar)
  CPU = 0.86
  Graphics = 0.57
  HDD = 2.78 (IBM DDRS 4GB)
  Maths = 3.11
   
  IIci-1 (68LC040/33MHz DayStar)
  CPU = 1.17
  Graphics = 0.75
  HDD = 3.29 (Seagate 2GB)
  Maths = 5.25
   
  IIci-1 (68040/33MHz DayStar)
  CPU = 1.31
  Graphics = 0.77
  HDD = 3.27 (Seagate 2GB)
  Maths = 12.14
   
  IIci-3 (68040/40MHz Mobius)
  CPU = 1.62
  Graphics = 0.77
  HDD = 2.62 (Quantum Fireball 2GB)
  Maths = 24.11

• IIci-3 (68040/40MHz Carrera without cache, but Cache Switch CP ON)
  CPU = 1.54
  Graphics = 0.73
  HDD = 2.18 (Quantum Fireball 2GB)
  Maths = 23.86
   
  IIci-3 (68040/40MHz Carrera without cache, but Cache Switch CP OFF)
  CPU = 1.54
  Graphics = 0.73
  HDD = 2.18 (Quantum Fireball 2GB)
  Maths = 23.86

Ten iterations of each test. CPU, Graphics (Radius 24nn) and HDD relative to Quadra 605 = 1. Maths relative to Quadra 650 = 1.

Under System 6.0.8, the system reported: 'No coherent System found. Just random scattered primitives.' :-*

Erratum: DayStar Turbo040 corrected to 33MHz, which may have some bearing on the comparison with the Mobius card (40MHz).
