Mobile CPU Specifications - Intel CPUs continued

Mobile Pentium II with full speed cache.
On 25 January, Intel released the first Mobile PIIs with full speed L2 cache at speeds of 333 MHz and 366 MHz. This was significant, as only the Intel Xeon had a similar high speed cache. A regular PII 's cache runs at half the speed of the processor. As a result of the high speed cache, Intel estimates that the 366 MHz Mobile CPU is 27% faster than its old 300 MHz Mobile CPU.
On 14 June, Intel released the 400 MHz Mobile Pentium II. The 400 MHz Mobile Pentium II is the first CPU that Intel has made with its 0.18 micron process (current CPUs are made with a 0.25 micron process) which allows the processor to become smaller and faster. Intel will also make this CPU using the old 0.25 technology (the 0.18 micron CPU uses about 20% less power than the 0.25 micron CPU). The new CPU will come in four different form factors: mini-cartridge, Ball Grid Array (the BGA package is less than a 10th of an inch high and weighs less than a nickel), micro PGA, and the Intel Mobile Module.

Mobile Pentium III Processors - Mobile Pentium III processors were available in 500, 450 and 400 MHz speeds. Systems with the new processors also feature a 100 MHz system bus, representing a 50 percent increase in bus bandwidth over Pentium II processor-based notebooks. The mobile Pentium III processor at 400 MHz operates at an extremely low voltage (1.35 volts) and is targeted specifically at mini notebook designs.

Pentium III SpeedStep - Prior to Christmas 2000, Intel promised that they would release new Mobile CPUs based on dual-speed Geyserville technology. Geyserville was the code name for Mobile Notebook CPUs that would run at full speed when plugged into a power source, and run at a slower, battery conserving speed, when using notebook batteries.
These new dual-speed CPUs were renamed SpeedStep and Intel released these new Pentium III CPUs at speeds of 650 and 600MHz. On April 24, 2000, Intel announced it was shipping the 700 MHz SpeedStep and on June 19, 2000 the 750 MHz SteedStep began shipping.
A low power, 600 MHz SpeedStep was also released on June 19 for mini-notebooks. Then, on September 26 2000, Intel released the 800 and 850 MHz SpeedStep CPUs and on March 19, 2001 the 900 MHz and 1 GHz SpeedStep were announced.
Per Intel, "Mobile Pentium III processors featuring Intel SpeedStep technology can dynamically switch frequency and voltage depending on whether the computer is running on batteries or is plugged into AC power. When running in Battery Optimized Mode, the processors run at a fast 500 MHz and 1.35 volts, significantly lowering CPU power consumption.
When a user plugs into an AC outlet, the notebook can automatically switch to Maximum Performance Mode, increasing the voltage to 1.6 volts and the speed to either 650 or 600 MHz (depending on the processor). These transitions happen in only 1/2000th of a second--so fast they are completely transparent to users, even if they occur in the middle of performance intensive applications such as; running performance-intensive applications such as playing a DVD movie. Users also have the freedom to select the Maximum Performance Mode even while running on batteries. Making that switch is as easy as clicking an icon at the bottom of the screen, with no reboot required.
Intel developed both the hardware and software components to make this technology work seamlessly, including the system BIOS, end user interface software, switch control ASIC and support in the chipset.
Intel SpeedStep technology is supported under all major PC operating systems, including Windows 98, Windows 95, Windows Me, Windows NT 4.0, and Windows 2000. No change to operating systems or software applications is needed in order to take advantage of Intel SpeedStep technology."

Intel Ultra Low Power Processors. On Janaury 30, 2002 Intel introduced the Celeron 500 MHz and Pentium III 500 MHz Ultra Low Power CPUs.
The Ultra Low Voltage mobile Pentium(R) III processor 500 MHz featuring Intel(R) SpeedStep(TM) technology brings high performance to mobile PCs weighing less than three pounds and measuring one inch in height. This processor operates at less than 1 volt and consumes less than half a watt of power in Battery Optimized Mode at 300 MHz.
Intel also introduced the Ultra Low Voltage mobile Celeron(TM) processor 500 MHz, delivering the industry's highest performance for the value sub-notebook segment.

On Spetember 16, 2002, Intel released the Low Voltage Mobile Intel Pentium III processor-M at 1000, 1220, and 1330 MHz (0.13-micron) and Ultra Low Voltage Mobile Intel Celeron processors at 700, and 733 MHz (0.13-micron).

In January 2003, Intel introduced the 900 and 933 MHz Ultra Low Voltage Mobile Pentium(R) III processor-M and the Low Voltage Mobile Celeron 866 and the Ultra Low Voltage mobile Celeron(TM) at 800 MHz.
