- List of AMD Athlon XP microprocessors
The
Athlon XP microprocessor fromAMD is a seventh-generation CPU targeted at the consumer market.Desktop CPU
=Athlon XP "Palomino" (Model 6, 180 nm)=* CPU-ID: 6-6-0
* All models support: "MMX, SSE, Enhanced 3DNow!"
=Athlon XP "Barton" (Model 10, 130 nm)=*CPU-ID: 6-A-0
* All models support: "MMX, SSE, Enhanced 3DNow!"
=Athlon MP "Barton" (Model 10, 130 nm)=* All models support: "MMX, SSE, Enhanced 3DNow!"
=Mobile Athlon XP "Thoroughbred" (Standard, 35 W TDP,Socket A )=* All models support: "MMX, SSE, Enhanced 3DNow!"
=Athlon XP-M "Thoroughbred" (Desktop Replacement, 72 W TDP,Socket A )=* All models support: "MMX, SSE, Enhanced 3DNow!"
=Athlon XP-M "Barton" (Desktop Replacement, 72 W TDP,Socket A )=* All models support: "MMX, SSE, Enhanced 3DNow!"
Athlon XP-M "Barton" (
Socket 563 )Notes
Note 1:The Athlon XP uses a
double data rate (DDR)front side bus meaning that the actual data transfer rate of the bus is twice its physical clock rate. The FSB's true data rate, 200, 266, 333 or 400 MT/s, is used in the tables and the corresponding physical clock rates are 100, 133, 166 or 200 MHz, respectively. The multipliers in the tables above apply to the physical clock rate, not the true data transfer rate.Note 2:Minimal quantity shipped.
Note 3:Used only in
Hewlett Packard personal computer s. The Inquirer reports that the Athlon 3200+ FSB333 AXDA3200KV4D processor was used in the Hewlett Packard d325 business desktop computer ( [http://www.theinquirer.net/?article=13040 link] ).Note 4:Was released with very limited quantities, most probably an OEM-only CPU.
Note 5:For traditional processors, including all K7 processors, the multiplier is the value multiplied to the speed of the FSB to get the clock speed of the processor. K8 processors, including the Socket 754 Athlon XP-M, have a memory controller integrated on the CPU die, replacing the traditional concept of FSB. The memory controller runs at the same frequency as the CPU itself, and is able to run the system memory at 200 MHz (using PC-3200 memory sticks) or at lower speeds (when using slower PC-1600, PC-2100 or PC-2700 RAM). Between CPU and chipset,
HyperTransport is used, running at 800 MHz on Socket 754. The multipliers here apply to the 200 MHz system clock frequency, not theHyperTransport speed.Note 6:The XP 2900+ is an OEM Barton chip (Made for SystemMax).
Note 7:Athlon XP processors were multiplier locked by AMD on or after week 30 of 2003 (0330). AMD did this by laser-cutting the L1 bridges, locking the CPU multiplierto that set via the L3 and L4 bridges.
If the CPU's L1 bridges are connected, the CPU is:
Unlocked - if the CPU was produced before week code 0333 with the L1 bridges connected.
There have been mulitple confirmations of both locked and unlocked CPUs between 0333 weeks and 0339.
Locked - if the CPU was produced from week 0340 and afterwards. These CPU versions are multiplier locked with the L1 bridges cut.
