What the Mobile Pentium III 500 MMC is
The Intel Mobile Pentium III 500 MMC is a 500 MHz single-core mobile module from October 1999. It runs one P6 Coppermine core at 500 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 16.8 W max on an MMC-2 card with a 400-pin connector on a 100 MHz front side bus with a 5x multiplier.
The card form with integrated host bridge suits build-to-order mobile lines, which is why MMC strings persist next to PGA twins at matching clocks. Socketed and soldered twins share the 500 name. The chip supports MMX and SSE.
Mid entry module clocks suit mainstream card-based laptops. The 5x integer ratio is clean for 100 MHz boards. That is why the 500 MMC shipped in mainstream mobile systems.
Socket and motherboard compatibility
The 500 MMC fits MMC-2 mainstream laptops with card support. It needs a 400-pin module board with a 100 MHz bus and a BIOS that lists Mobile 500 MMC. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Mainstream card laptops are the natural match. Boards listing the MMC 500 accept the card with a 16.8 W spreader.
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. Mainstream 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, no faster MMC Coppermine card exists in this block, so the 500 MMC tops the module line here. A Mobile Pentium III 450 MMC drops 50 MHz at 15.5 W. A socketed Mobile Pentium III 500 such as Intel Mobile Pentium III 500 is the PGA twin.
A move to SpeedStep cards needs battery tables. The MMC-2 page lists the range. Note: the queue row lists 15 W; this page uses the verified 16.8 W max shared with the PGA twin.
