What's Hyper Transport?

ChrisAdan650 · Nov 4, 2004, 05:18 AM

I'm buying a socket 754 motherboard and it lists the FSB at 1.6 GHz. I'm guessing that this is capable using Hyper Transport technology. What is hyper transport and how does it work? Is there really a different between an 800mhz FSB and 1.6? How will be able to run it at 1.6ghz myself? Thanks in advance.

The HyperTransport is actually 800MHz, bi-directional (some sites like to call that 1600). It's 200MHz with 4x multiplier, like Intel's FSB. But it's not really a FSB since A64 has the memory controller on-board.

On-chip, that is...

also there is a 1200mhz version

weather it's out yet or not

was trying to keep things simple as he asked about socket 754 and 800 HTT

Thank you very much for the links. I was wondering, is there a noticeble difference between the 800 HTT and 1.6 HTT?

well as he said, some sites like to call it 1.6HTT but it really is just 800HTT bi-directional(which is the same on something called 800HTT)

The 800htt is 1600htt; it goes both ways kinda like DDR ram

So right now there are only two HTT speeds out; one is the 800MHz(or 1.6GHz up/down) htt for socket 754 cpus and 1000MHz(or 2GHz) for socket 939. Anything over 800MHz HTT doesn't really do much anyways and most 754 boards allow for 1GHz htt now also(x5 multi).
