quad pumped??

[jktrader]

What does it mean a cpu is quad pumped. does it mean dual cores are quad pumped as well as quad core cpu's or does it pertain to quad cpu only and dual cores are dual pumped..

 

[Shortass]

It has to do with the the way memory is accessed. All mainstream Intel CPUs in at least the past 5 years or so are quad pumped, IIRC. Someone will likely give a more comprehensive explanation shortly.

Intel CPUs can transfer four data bits every FSB clock cycle, giving an effective 4x clock rate. This is why you will often see them listed as 1066 (4 x 266) or 1333 (4 x 333) FSB processors.

Right. It means the actual clock frequency of the bus is for example 200MHz, yet it's able to transfer data as if it were running at 800MHz.

And it has absolutely nothing to do with quad core, dual core, or single core.

"Quad pumped" = QDR (Quad Data Rate)

Much like RAM's DDR (Double Data Rate)

When I wanted to get into building my own PCs I went down to the local library. Mine had several books on the subject, including from the "For Dummies" series. Some of the information may be dated, as that's the nature of the PC business, but in general it was very helpful. A lot of things haven't changed for years anyway - the basic parts of a PC, the basics of how memory works, video cards, hard drives, etc.

At the very least it will get you enough of an understanding to help you read higher level texts, articles on the net, etc.

I think the internet is the best source for PC information. As DSF said, most books you find are usually outdated. Publishing is slow compared to PC progress. By the time a book gets published it's no longer about current technology. PC books are for PC history, and not for PC current events.
