ATHLON 64 3400 CPU

[JK949]

I have seen 2 754 socket athlon 3400 cpu's on line. One has a 1 meg L2 cache and one has
512. They are both advertised as 2.20 gig and are the same price. I have an MSI K8T NEO FISR
with an 800 fbs. Both of the cpu's state a 1600 fbs. What's the real skinny on 754 cpu's and boards.
Is my board going to work with any 754 socket cpu or is there a difference.

The 800 listed on your mobo is for Hypertransport. HT is doubled from what ever the clock speed you run your memory at multiplied by the HT multi. So at a FSB of 200 and HT multi of 4x you are at 800 then double that for the HT speed. This is where you see the 800/1600. Yes both of those 754 CPUs will work for you. One is a Newcastle core and one is a Clawhammer.

Newcastle's better

Thanks for the info. Do you know where i can go to get accurate info on 754 cpu's such as
clock speeds and L2 cache

L2 cache is easy to remember. Clawhammers have 1mb, Newcastles have 512kb.

Clock speed for the Clawhammers is always less than Newcastle.

On the 3200+, Clawhammers are 2ghz / 1mb. While Newcastles are 2.2ghz/512kb
