Fsb???????????????????????????????

[The Unknown]

Hey guys, what does 1066 FSB mean???????

[gannu_rox]

^^^
FSB is the physical bi-directional data bus that carries all electronic signal information between the central processing unit (CPU) and the northbridge.

A fast CPU can be delayed when it must access other devices attached to the FSB. Thus, a slow FSB can become a bottleneck slowing down a fast CPU.

The frequency at which a processor (CPU) operates is determined by applying a clock multiplier to the front side bus (FSB) speed. For example, a processor running at 550 MHz might be using a 100 MHz FSB. This means there is an internal clock multiplier setting (also called bus/core ratio) of 5.5; the CPU is set to run at 5.5 times frequency of the front side bus: 100 MHz × 5.5 = 550 MHz. By varying either the FSB or the multiplier, different CPU speeds can be achieved.

A slow FSB will cause the CPU to spend significant amounts of time waiting for data to arrive from system memory.

what is north bridge ?

[gannu_rox]

The Northbridge plays an important part in how far a computer can be overclocked, as its frequency is used as a baseline for the CPU to establish its own operating frequency. In today's machines, the chip is becoming increasingly hotter as computers become faster. It is not unusual for the northbridge to now use some type of heatsink or active cooling.

Look into ur mobo... D heatsink dats adjacent to d CPU heatsink; is atop the northbridge...

thx.

Northbridge houses the memory controller.Infact that is the most important job it does. This is in case of Intel,in Case AMD K8, that is done by CPU itself.The AGP or PCIe communication is also done by Northbridge.Generally, USB ports,IDE controllers, onboard LAN etc. is handled by the Southbridge.

Hope that helps.

You are confusing me. Now what is southbridge?

[gannu_rox]

well no tech spkin here but in layman's lang, southbrigge controls the operation of ur USB ports, PCI ports, Audio, onboard LAN etc... Their speed n stuff....

Thnks.

STOP THIS TOPIC NOW AS PROBLEM SOLVED

[gannu_rox]

Phew.... Thanx dood...

[Anindya]

So in that case AMD is better as far as memory controller is concerned. Coz since the controller is within the processor core it spends less time for data transfer right? Plz let me know.

[The Unknown]

I think i will have to ask a mod to lock this topic. Can't you read that red banner?

[gannu_rox]

^^^Heh he.. Chill out Unknown bro...

[Anindya]

@ Unknown why getting angry buddy?
@ Gannu can u plz clear my doubt?

[gannu_rox]

^^ Dat was rite actually... Now tho coz of the inc cache Intel outperforms AMD.. AMD with its new Agena will def outperform C2Ds no doubts...

Well the success of C2D or Core Architecture is more or less because of the architectural improvements.Not that the cache didnt help but it wasnt the only thing responsible.To explain in simple terms, Intel's Last Netburst based CPU, 'Presler' based on 65nm and Dual Core, couldnt beat AMD A64 X2 even though it had 4MB L2 Cache, same as Conroe.Got the point ?
