Intergrated into chip for cpu's?
hello,
I was looking at some cpu's on newegg and I noticed some of the cpu's said there fsb was intergrated into chip, what does this mean? http://www.newegg.com/app/viewProdu...-103-438&depa=0 also does the operating frequencey mean the speed in which the processor can transfer data? |

Your link is broken, but you must be talking about the amd 64's. The FSB integrated into the chip means that it doesn't have to communicate with the northbridge much, most of those functions are brought onto the cpu itself, including the memory controller.
Operating frequency is the cpu clock speed, like 2.8 or 3.2 in an Pentium. Can't compare those numbers head to head though.

Thanks for the information but I have a couple more questions.
1. Whats the northbridge? 2. To optimize the ram and cpu interaction's, don't you have to have a higher ram FSB speed than your processor's FSB speed? 3. Is pc3200 the same thing as 400mhz, and pc2700 the same thing as 333mhz and so on? |

1. Northbridge is part of the chipset. It communicates w/ the cpu, and usually handles the agp and pci busses, L2 cache, and memory conroller.
2. You want to match the fsb and the ram speed so they can run 1:1 (in sync) 3. the pcxxxx and ddrxxx notations are different ways of referring to the same thing, so pc3200 is ddr400 http://www.hardwarecentral.com/hard...reports/2243/4/ explains |

Thanks for the link. I have 3 last questions... On the link I gave you of the processor it did say it was +3200 but the operating frequency says 2.2 ghz. Arn't the +3200 and operating frequency soppose to be the same thing?
Also is it ok to have the ram FSB speed to be higher than the processor's FSB? I wold think so but Id like to here if you think so. Last one, when people say ddr400...thats the same thing as FSB of 400Mhz, right? Last edited by NanoWarrior : April 8th, 2004 at 03:22 PM. |

The 3200+ is an indicator of performance. AMD's don't work quite the same as Intel's, so they use the performance numbers rather than the operating frequencies (which are smaller, and might make people not buy amd).
No problem having RAM faster than the FSB, it will just downclock to match. The RAM speed is really the "ceiling" that it has been tested to to maintain its stated timings at the rated voltage. DDR400 means it can run at a 1:1 divider with a FSB of 200 mhz (200x2=400). If you want to learn more, http://www.devhardware.com/c/a/Memo...th-And-Timings/ is a good article on memory. |
