The Intel Pentium 4 Processor and The 915G Chipset

The processor socket with the processor mounted 

 

The Northbridge or the Memory Controller Hub(MCH), a part of the Intel Hub Architecture.

The northbridge joins the memory(RAM) and the onboard graphics and the southbridge to the processor , due to the big chunks of data passing through it and higher bandwidth, it often gets heated due to which it is provided with a heatsink and sometimes a fan.

The best way to identify a northbridge on any chipset is that it is the nearest and the biggest chip near a processor. 

  

The processor and the northbridge

The DDR-2 RAM chip with a 533MHz speed (generally found in old pc's nowadays computers are equipped with a high speed DDR-3 or DDR-4 RAM with speeds which are above 1200MHz)

 

This black chip here is the southbridge or the Input-Output control hub(I/O hub) which joins the USB ports, PCI express slots, Optical drives, Hard drives, and most important the BIOS to the northbridge(MCH) leading finally to the processor.

Often it is much slower than the northbridge and has lesser bandwidth wnd generally does not need a heatsink(except some)

 

The LAN card which manages the ethernet comes mounted on PCI express slot

The Pentium-4 Processor with an amazingly fast clock speed of 2.4GHz(2.4 billion calculations per second),this processor of intel was greatly optimised for the Intel Hyperthreading Technology which comes to great use while multitasking.Also of the hundreds of millions of transistors on this chip, each one is the size of 90nm(each transistor just about 400 atoms thick), this is the prescott edition of P-4 processor
