What the Mobile Pentium III 450 MMC is
The Intel Mobile Pentium III 450 MMC is a 450 MHz single-core mobile module from October 1999. It runs one P6 Coppermine core at 450 MHz with no turbo, so 1 core gives 1 thread. Cache is 256 KB of full-speed L2 with 32 KB of L1 on a 180 nm process. Power is rated at 15.5 W max on an MMC-2 card with a 400-pin connector on a 100 MHz front side bus with a 4.5x multiplier.
The card form pairs the processor with the host bridge controller for factory-matched timing, which is why module boards list MMC strings separately from socketed PGA strings. Socketed and soldered twins share the 450 name on their own forms. The chip supports MMX and SSE.
Entry module clocks suit full-size laptops built around card replacement. The 400-pin connector allows card swaps with the same chipset generation. That is why the 450 MMC shipped in service-friendly mobile systems.
Socket and motherboard compatibility
The 450 MMC fits MMC-2 module laptops with Coppermine card support. It needs a 400-pin module board with a 100 MHz bus and a BIOS that lists Mobile 450 MMC. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Card-based laptops are the natural match. Boards listing the MMC 450 accept the card with a 15.5 W spreader. PGA and BGA boards take their own forms.
Memory, PCIe and cooling
Memory is SDRAM through the module and baseboard chipset, matched to the board slots. The card carries its own northbridge section. Boards commonly run PC100 pairs.
A 100 MHz front side bus ties the module to the baseboard, while expansion hangs off the chipset. No PCIe lanes originate on the card. Cooling uses the module spreader for the exact laptop.
Upgrade paths
On the same form, a Mobile Pentium III 500 MMC such as Intel Mobile Pentium III 500 MMC keeps the laptop for 50 MHz more. A socketed Mobile Pentium III 450 such as Intel Mobile Pentium III 450 is the PGA twin on socket boards.
A move to SpeedStep cards needs battery tables. The MMC-2 page lists the module range for planning.
