Talk:CPU multiplier

message: PLL clock multiplier should be added somewhere somehow or in the PLL section or a separate clock recovery/clock generations section Larytet (talk) 21:14, 27 December 2007 (UTC)

message: In terms of circuitry, what is a clock multiplier?  How does it work?  Back in electronics we covered clock dividers - which can reduce the clock frequency, but not circuits to increase the clock frequency.  —Preceding unsigned comment added by Zodon (talk • contribs) 23:40, 17 March 2008 (UTC)
thread_title:  What is a clock multiplier? 

message: What I need to know is: which is better, makes for a faster computer that does not sieze up, a high or low fsb/core ratio-clock multiplier?  I get confused between the explanations using one concept or the other.

message: "On these systems, the clock multiplier refers to the ratio of the CPU clok speed to the HyperTransport clock speed (typically 800 MHz or 1 GHz, as of 2007)"
This statement is false. All AMD Athlon 64 systems use a 200MHz base clock generated in the same manner as Intel's FSB. The CPU's multiplier is based off this clock, as are the Hypertransport links.  —Preceding unsigned comment added by 66.158.176.194 (talk) 05:59, 11 July 2008 (UTC)

message: On the topology diagram, is the Clock Generator the Clock Multiplier?
Or are Clock Generators and Clock Multipliers different things?  —Preceding unsigned comment added by 92.238.93.209 (talk) 03:08, 24 October 2008 (UTC)
replies: text: Yes, they should be. The clock generator's purpose is to generate a clock signal which the clock multiplier uses to output a higher clock signal with a higher frequency. Rilak (talk) 08:38, 25 October 2008 (UTC)
replies: text:  I agree with Rilak. The entire point of a clock multiplier is that the maximum frequency that wires on the motherboard can carry is much lower than the maximum frequency of the wires inside an integrated circuit. So to run a CPU at amazingly high clock frequency, we can't pipe in that signal from the outside. Instead, we pipe a much lower frequency signal from the clock generator chip to the CPU chip, and then a clock multiplier (inside the CPU) uses that as a reference signal to generate the desired amazingly high clock frequency. How can we make this clearer in the article? --68.0.124.33 (talk) 21:07, 17 December 2008 (UTC)

thread_title:  Clock Multiplier and the diagram 

message: I removed the outdated tag that said something about smartphones. The information in the article is not outdated in the sense that any information is wrong. However, If anyone wants to add examples of smartphone ARM chips or something, that may be what the IP editor was looking for. I don't really see the point as it is the same concept for any CPU or IC.
Having said that, I was hoping to find more details on how the multiplier actually (electronically) works in this article. This could be actually quite different for different architectures and newer chips. Maybe that's too technical for WP though. Guess I'll keep looking. Autumn Wind (talk) 17:59, 24 January 2017 (UTC)
