Intel Mobile Pentium III 600 socket: Socket 495

What the Mobile Pentium III 600 is

The Intel Mobile Pentium III 600 is a 600 MHz single-core mobile processor from January 2000. It runs one P6 Coppermine core at 600 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 20 W max in a Socket 495 micro-PGA2 package on a 100 MHz front side bus with a 6x multiplier at 1.6 V high and 1.35 V battery mode.

The chip supports MMX, SSE and SpeedStep. A soldered BGA2 counterpart exists; this page covers the socketed package per the socketed-only rule.

Socket and motherboard compatibility

The 600 fits Socket 495 thin 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 600. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Thin SDRAM laptops are the natural match. Boards listing the Mobile 600 accept the chip with a 20 W pipe.

Memory, PCIe and cooling

Memory is SDRAM through the board chipset, matched to the board slots. The CPU has no memory controller. Thin 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 20 W.

Upgrade paths

On the same socket, a move to a Mobile Pentium III 650 such as Intel Mobile Pentium III 650 keeps the laptop for 50 MHz more. A Mobile Pentium III 500 LV on Micro-BGA2 is the soldered low-voltage counterpart with no socket path.

A move to Pentium III-M needs 512 KB cache support. The Socket 495 page lists the range.
