Intel Celeron 1300 socket: Socket 370

What the Celeron 1300 is

The Intel Celeron 1300 is a 1300 MHz single-core value processor from January 2002. It runs one P6 Tualatin core at 1300 MHz with no Hyper-Threading, so 1 core gives 1 thread. Cache is 256 KB of L2 at full core speed on a 130 nm process. Power is rated at 33 W in a Socket 370 FC-PGA2 package with a 100 MHz front side bus and a 13x multiplier.

Tualatin-256 doubles Coppermine-128 cache from 128 KB to 256 KB at the same 130 nm base, which is why Celeron 1300 parts at 1300 MHz outperform Coppermine Celeron parts at similar clocks. Intel placed the 1300 near the top of the Tualatin Celeron line before the 1400 arrived in May 2002. The chip supports MMX and SSE. Pentium III Tualatin parts at the same 1300 MHz offer 256 KB with an 133 MHz bus as a mainstream alternative, so bus speed separates value from mainstream at identical frequency.

Value clocks with a slow bus suit office towers with SDRAM memory. The 100 MHz bus keeps board cost low while the 256 KB cache preserves responsiveness in single-task use. That is why the 1300 shipped in budget towers with integrated graphics.

Socket and motherboard compatibility

The Celeron 1300 fits Socket 370 blue Tualatin boards with a 100 MHz bus and Tualatin Celeron support. It needs a board with FC-PGA2 power delivery. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Budget SDRAM towers are the natural match. Boards listing Tualatin Celeron 1300 accept the chip with a 33 W cooler. White Coppermine-only boards need a Tualatin compatibility check.

Memory, PCIe and cooling

Memory is SDRAM through the board chipset, with PC100 modules as the common choice. The CPU has no controller.

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 Socket 370 lug with a 33 W heatsink under the 180 gram cap.

Upgrade paths

On Socket 370 the step is the Celeron 1400 Tualatin at 1400 MHz with the same cache. Pentium III Tualatin parts offer 512 KB options as larger lifts. Beyond Socket 370 a move to Socket 478 needs a new board. The 1300 lifts with the lever, so swaps need no solder work.
