Intel Mobile Pentium III 750 socket: Socket 495

What the Mobile Pentium III 750 is

The Intel Mobile Pentium III 750 is a 750 MHz single-core mobile processor from June 2000. It runs one P6 Coppermine core at 750 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 24.6 W max in a Socket 495 micro-PGA2 package on a 100 MHz front side bus with a 7.5x multiplier at 1.6 V high and 1.35 V battery mode.

SpeedStep drops the chip to 600 MHz at 1.35 V in battery mode with about 14 W, which is why the 750 suited mainstream laptops with balanced battery targets. Intel sold the Mobile 750 in June 2000. The chip supports MMX, SSE and SpeedStep. A soldered BGA2 counterpart with the same silicon exists; this page covers the socketed package per the socketed-only rule.

Mid mobile clocks with a full cache suit Socket 495 mainstream laptops with SDRAM. The 7.5x ratio is standard for 100 MHz mobile boards. That is why the 750 shipped in mainstream laptops.

Socket and motherboard compatibility

The 750 fits Socket 495 mainstream 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 750. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Mainstream SDRAM laptops are the natural match. Boards listing the Mobile 750 accept the chip with a 24.6 W pipe. Soldered BGA2 boards cannot accept the pinned package.

Memory, PCIe and cooling

Memory is SDRAM through the board chipset, matched to the board slots. The CPU has no memory controller. Mainstream 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 24.6 W.

Upgrade paths

On the same socket, a move to a Mobile Pentium III 800 such as Intel Mobile Pentium III 800 keeps the laptop for 50 MHz more. A Mobile Pentium III 700 such as Intel Mobile Pentium III 700 drops 50 MHz.

A move to Pentium III-M needs 512 KB cache support. The Socket 495 page lists the range. Note: the queue row lists 16 W typical; this page uses the verified 24.6 W max.
