Identifying T-bird vs. K7 (help!)
I've got an AMD athlon 800MHz K7 processor here, but I can't seem to figure out if it's a K7 or a T-bird. The difference between the thunderbird and the K7 is that the K7 has a 256KB L2 cache and the T-bird's is only 128KB, but is there any way to tell by the casing? I don't have a computer with a slot A to try it out on either...
Also, what's the difference between the K7 and the "K7 classic"? Is there a difference or are they the same processor?
Any help would be greatly appreciated.
"Classic" Athlons are Slot A Athlons with 512kb off-die L2 cache which works at half of CPU speed.
Newer "Thunderbird" core is available only at Socket A, and has 256kb of full-speed on-die L2 cache.
The perfrormance is about the same, with T-Bird winning hardly by mere 5%.
Besides, programs like SiSoft Sandra will tell you which one you have.

Thanks for the help ND.
So are you saying the K7 has 512KB of off-die cache and NO on-die L2 cache?
I would like to put it up on ebay, but I saw some people listing their K7's as thunderbirds and it got me really confused, and I really don't want to have people bidding on a "false" auction. Because I don't want to falsely advertize my processor.
So it looks like I've got a slot A (that I can physically tell ) AMD athlon 800MHz K7 processor with 512kb of off-die L2 cache.
1.Does it have any on-die L2 cache?
2.Do you know the size of the L1 cache?
Thanks a lot for the help.
"Slot A AMD Athlon K7 800MHz/512kb L2". Correct.
2. 64kb data/64kb instructions - 128kb total.
Thaks a lot ND, you've earned my karma points!
You have a nice day.
