Notes

  
 
  1. Several Intel and AMD and Intel processors are dual-core. This means they have two individual CPUs in one chip. Some are quad-core, which means they have four individual CPUs in one chip.
  2. Intel's Hyperthreading technology uses two pipelines in one CPU, which gives the operating system the appearance of two CPUs. When their first dual-core CPUs came out, Intel discontinued this technology. It has since been reincorporated. In some instances, a single quad-core CPU will appear as eight CPUs to the operating system when combined with HT technology.
  3. The AMD Opteron series processors are utilizing a new numbering scheme. The 14x series are 1-way, the 24x series are 2-way, and the 84x series are 8-way. This is illustrated respectively with their speeds listed.
  4. Several newer Intel Pentium 4 HT, Pentium 4 M, and Celeron D series processors are utilizing a new numbering scheme. The Pentium 4 D processors are deemed 8xx and 9xx, the Pentium 4 HT processors are deemed 5xx, the Pentium 4 M procesors are deemed 7xx, and the Celeron D processors are deemed 3xx.
  5. Several newer Intel Pentium 4 HT and Pentium 4 D processors have three cache levels (L1, L2, and L3).
  6. Intel's Itanium 2 processors come with many L3 cache sizes, including 1.5MB, 3MB, 4MB, 6MB, or 9MB.
  7. AMD's Hypertransport Bus technology uses a scaled multiple of a base speed of 200 MHz. Although all HT-compatible bus speeds are listed as 800 MHz or 1000 MHz, some MB manufacturers list it as 1600 MHz and 2000 MHz. This is the speed indicated here.
  8. All AMD Athlon 64 and newer CPUs include an integrated memory controller, dating back to 2004. Intel did not integrate a memory controller until their 45nm line of CPUs came out in 2007.
  9. Specified rates for the Cyrix processors, AMD's K5, AMD's Athlon MP (1500 and above), AMD's Athlon XP, and AMD's Athlon 64 are PR ratings, not true speeds. The PR rating is a comparitive speed against Intel's processors.
  10. "B" on Intel processors denotes support for a 133 MHz system bus.
  11. "E" on Intel processors denotes support for Advanced Transfer Cache and Advanced System Buffering.
