Athlon or Thunderbird - Ways to tell apart?

When I bought my this computer back in December, I'm sure I got and AMD Thunderbird 800Mhz put in. Yet in all of the benchmark programs I use and under System Properties, if says I have an AMD Athlon 800Mhz. How can I tell which one I have short of opening the thing up as my dad won't let me void the warranty

And anyway, what is the difference between the two as they are both the same speed?

some times programes reconize the thunderbird as an athlon cuz its an athlon thunderbird. The thunderbird has faster L2 cache then the classic athlon.

The thunderbird has on-die L2 cache, like the L1, working at full speed (ie: if you have a TBird 800MHz, your L2 cache will work at 800MHz, versus I think 1/2 speed with athlon classic). And I am not sure, but I think Athlon Classic has more L2 than tbird : classic has 512 KB of L2 cache, and TBird has 256KB, but as tbird's cache is working faster, it's more efficient, and more performant !

Almost forgot, Welcome to the forums !!!

Run the utility and it will tell you what you have - there will be 256K of full speed L2 cache if it's a thunderbird core.

An thunderbird is an athlon!! Thunderbird is just the codename for the cpu.
