The Plot Thickens: P4 2.2 GHz vs. Athlon XP 2000+
How long has this rivalry been going on? It seems to me that the AMD vs. Intel battle is becoming an everyday event in the CPU market with supporters on both sides. From an overclockers point of view, AMD is ahead of the game with its Athlon XP 1900+ versus Intels Willamette 2 GHz Pentium 4. That is the case but Intel and AMD have just released newer CPUs and they are here for our torture tests to see who is the CPU champion.
The Contestants
Intels new Northwood Pentium 4 has an increased clock speed and double the L2-Cache. This equals to a 533 MHz difference in clock speeds between the Northwood Pentium 4 @2200 and the Athlon XP 2000+ @1660 MHz.
