What the Mobile Pentium III 450 is
The Intel Mobile Pentium III 450 is a 450 MHz single-core mobile processor from October 1999. It runs one P6 Coppermine core at 450 MHz with no turbo and no SpeedStep, 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 in a Socket 495 micro-PGA2 package on a 100 MHz front side bus with a 4.5x multiplier at 1.6 V.
Micro-BGA2 soldered cards and MMC-2 modules carry the same Mobile 450 name at 450 MHz for thinner boards, which is why three pages share the model line across packages. This page covers the socketed micro-PGA2 package per the socketed-only rule; a 450 MMC module such as Intel Mobile Pentium III 450 MMC has its own page. The chip supports MMX and SSE with QuickStart.
Entry mobile clocks with a full cache suit Socket 495 value laptops with SDRAM. The 4.5x ratio is standard for 100 MHz mobile boards. That is why the 450 shipped in budget mobile systems.
Socket and motherboard compatibility
The 450 fits Socket 495 value laptops with Coppermine support. It needs a 495-pin micro-PGA2 board with a 100 MHz bus and a BIOS that lists Mobile Pentium III 450. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Value SDRAM laptops are the natural match. Boards listing the Mobile 450 accept the chip with a 15.5 W pipe. Soldered and module boards take their own forms.
Memory, PCIe and cooling
Memory is SDRAM through the board chipset, matched to the board slots. The CPU has no memory controller. Value boards commonly run PC100 pairs.
A 100 MHz front side bus ties the CPU to the chipset, while AGP and PCI hang off the chipset. No PCIe lanes originate on the die. Cooling uses the laptop heat pipe for the exact chassis, rated for 15.5 W.
Upgrade paths
On the same socket, a move to a Mobile Pentium III 500 such as Intel Mobile Pentium III 500 keeps the laptop for 50 MHz more. A 450 MMC module is the card twin on module boards.
A move to SpeedStep models needs battery-mode BIOS tables. The Socket 495 page lists the mobile range for planning.
Frequently asked questions
What socket does the Mobile Pentium III 450 use?
