5. 1.5 GHz Pentium-M: The Slightly Slower 1.6 GHz Pentium-M
As for chip design, the cache architecture and size and the energy-saving functions are concerned, there is no difference between the 1.5 GHz Pentium-M and the current top model with 1.6 GHz. The 1.5 version also has energy-saving functions such as the improved Enhanced Speedstep, Deeper Sleep and IMVP.
There are differences, however, in some Speedstep workings.
| Enhanced Speedstep Technology operating Points | |
|---|---|
| Pentium-M 1.60HGz | Pentium-M 1.50HGz |
| 1,6 GHz/1,484V | 1,5 GHz/1,484V |
| 1,4 GHz/1,420V | 1,4 GHz/1,452V |
| 1,2 GHz/1,276V | 1,2 GHz/1,356V |
| 1 GHz/1,164V | 1 GHz/1,228V |
| 800MHz/1,036V | 800MHz/1,116V |
| 600MHz/0,956V | 600MHz/0,956V |
Speedstep operating points in the 1.6 GHz and 1.5 GHz Pentium-Ms.
For one thing, the speed jump to the next level is just a hundred megahertz. For another, the CPU needs a slightly higher voltage for the various operating points.
Naturally, the user can also adapt CPU performance to his/ her tastes with this processor model. The power scheme selection is used for this.
| Windows XP Power Schemes | AC Power (Pentium-M 1.5 GHz) | Battery // DC (Pentium-M 1.5 GHz) |
|---|---|---|
| Home/Office Desktop | None (1.5 GHz Always) | Adaptive (600 MHz <...>1.5 GHz) |
| Portable /Laptop | Adaptive (600 MHz <...>1.5 GHz) | Adaptive (600 MHz <...>1.5 GHz) |
| Presentation | Adaptive (600 MHz <...>1.5 GHz) | Degrade (600 MHz) |
| Always On | None (1.5 GHz Always) | None (1.5 GHz Always) |
| Minimal Power Management | Adaptive (600 MHz <...>1.5 GHz) | Adaptive (600 MHz <...>1.5 GHz) |
| Maximum Battery | Adaptive (600 MHz <...>1.5 GHz) | Degrade (600 MHz) |
CPU performance is heavily dependent on the choice of power scheme in the system control settings.
