|You really need to work on your search skills. I assume you're only interested in socket A CPUs? There were several different cores used throughout the K7 series, different FSB speeds & different L2 cache sizes.|
- the early Athlon was based on the Thunderbird core. It ran at either 200MHz or 266MHz FSB & had 256k L2 cache.
- the Athlon XP was was an improved version of the Athlon. It went thru several core revisions - Palomino, Thoroughbred, Barton. The AXP ran at either 266MHz, 333MHz or 400MHz FSB depending on the core. AXPs based on the Barton core have 512k L2 cache, all the rest have 256K L2.
- the early Durons (Spitfire & Morgan cores) were stripped down versions of the Athlon. They ran at 200MHz FSB & had only had 64k L2 cache. There was also an Applebred core which was a stripped down version of the Athlon XP Thoroughbred. It ran at 266MHz FSB but still only had 64k L2.
- the Sempron is nothing more than an Athlon XP with a new name. AMD wanted to continue to use the Athlon name for it's new 64-bit K8 series of CPUs (Athlon 64), so they renamed the AXP. The Sempron was based on the Thoroughbred, Thorton or Barton core. Almost all Semprons run at 333MHz & have 256k L2 cache except for the rare Sempron/Barton.
The fastest of the K7 series was the Athlon XP 3200+ Barton. It ran at 2.2GHz at 400MHz FSB.
