"It is a symbol of Irish art. The cracked lookingglass of a servant." -- James Joyce
Hmm... This doesn't feel like a run-on sentence to me, exactly. I don't know if there is a tech term for what I think is really wrong with it; I'd call it deficient reference.
I think "Leading the industry again" is shorthand for "AMD is leading the industry again," so each is a complete sentence, and the whole is a run-on. I stand by my claim.
