C. Processors (cont.)
I don�t understand these processor numbering systems. What chip goes with which socket/slot?
Intel Processor Designations
Pentium IV
Intel uses a A and B designation to denote Pentium IV Processor Type and Bus Speed.
An A designation denotes a Northwood Class CPU. These cpu�s use a Socket 478, have an additional 256k l2 cache (for 512k Total) and are considerably faster and run cooler then their Williamante counterparts (Socket 423, 256k l2 cache). Northwood�s are not backwards compatible with Williamante, and will require new motherboards.
A B designation denotes a 533 FSB Northwood. These cpu�s are Socket 478 but run at a 533 FSB. (Thus the motherboard must support this increased FSB)
SMT processors do not currently have a separate designation. Just look out for a higher price and a Hyperthreading or SMT denotation.
Coppermine
Intel uses a E, B, EB, and T designation for their Coppermine/Tualatin Line.
If an E follows the processor, ex 800E, it means it is an 800 megahertz Coppermine running at 100 Front Side Bus.
If a B follows the processor, ex 600B, it means the processor is a Pentium III, non Coppermine that runs at 133 Front Side Bus.
If an EB follows the processor, ex 600EB, it means the processor is a Coppermine that runs at 133 Front Side Bus.
There are two possible chip configurations for Pentium III boards, Slot 1, Slot 2, and FC-CPU or Socket 370.
Slot 1 is designated by a SECC2 configuration and will only work on Slot 1.
Slot 2 is a modified SECC2 for Xeon Processors. Slot 2 chips do not run in Slot 1 and vice versa.
FC-CPU is the socketed and latest version of Intel processors. It flips the core of the processor up for direct contact with the heatsink/cooling apparatus. Thus the term FC or Flip Chip. These chips only work in FC-CPU motherboards or in a Slot 1 motherboard if you use a slocket. (A slocket is a FC-CPU to Slot 1 Converter card.)
AMD Processor Designations
AMD uses an extremely confusing PR rating system to denote their various processor steppings. Any processor denoted with an XP or MP after a # is using this system. All of these processors are Socket 462 (Socket A).
There are four variants of this system. The initial XP/MP line, including the initial thoroughbreds, the rev B thoroughbreds, the rev B Tbred�s at 333 FSB, and the upcoming Barton�s. (Except for the Barton�s and 333 Tbred�s, All processors here use a 266 FSB)
Athlon XP/MP PR System
Athlon 1500+ XP 1.33 Gigahertz
Athlon 1600+ XP 1.40 Gigahertz
Athlon 1700+ XP 1.47 Gigahertz
Athlon 1800+ XP 1.53 Gigahertz
Athlon 1900+ XP 1.60 Gigahertz
Athlon 2000+ XP 1.67 Gigahertz
Athlon 2100+ XP 1.73 Gigahertz
Athlon 2200+ XP 1.80 Gigahertz (Tbred Rev A) | Athlon Tbred Rev B
Athlon 2400+ XP 2.00 Gigahertz
Athlon 2600+ XP 2.13 Gigahertz
Athlon 2800+ XP 2.27 Gigahertz | Athlon Tbred Rev B (333 FSB)
Athlon 2300+ XP 1.87 Gigahertz
Athlon 2500+ XP 2.00 Gigahertz
Athlon 2700+ XP 2.13 Gigahertz
Athlon 2900+ XP 2.27 Gigahertz | Barton (512k l2 cache, 333 FSB)
Barton 2800+ XP 2.13 Gigahertz
Barton 3000+ XP 2.27 Gigahertz |
Are you confused? So is everyone else. What is AMD thinking?
