Celeron and Celeron D
*TDP = Thermal Design Power, or the nearly the maximum amount of heat a processor can dissipate.
**EOL = End-Of-Life (aka discontinued)

last modified: 2006-02-09 14:19:41 | | | The Low Voltage AMD XP Mobile are designed for longer battery life by cutting down the voltage & thermal dissaption. At 1.25V and giving off 25W, making it a very attractive competitor to the Intel Penitum-M mid-clock (1.2-1.6Ghz.)
There are 2 different cores for the current low voltage (TD 25W)
Throughbred Core (256K level 2 cache):
AMD 1400+ (1.2Ghz @ 200 & 266FSB)
AMD 1500+ (1.3Ghz @ 200FSB /1.33Ghz @ 266FSB)
AMD 1600+ (1.4Ghz @ 200 & 266FSB)
AMD 1700+ (1.47Ghz @ 266FSB)
AMD 1800+ (1.53Ghz @ 266FSB)
Barton Core (512 level 2 cache):
AMD 1800+ (1.4Ghz @ 200FSB & 266FSB)
AMD 1900+ (1.47Ghz @ 266FSB)
AMD 2000+ (1.53 @ 266FSB)
AMD 2100+ (1.6 @ 266FSB)
AMD 2200+ (1.67 @ 266FSB)

And, since every clock cycle uses up precious power, Intel spent a lot of time finding a way to boost the IPC (instructions per clock) performance per clock of the Pentium III core. While the Pentium-M is loosely based around the P3 core, it is in no way ancient or outdated. It does incorporate many P4 features.
The added L2 cache also improves IPC performance, and the Pentium-M seems to be able to really shine in floating point applications.
Although clocked slower, the performance of a 1.6 Ghz P-M outpaces the performance of a 2.2 Ghz P4-M. The Pentium M is very roughly 1.5-1.6x as fast as a P4 for gaming. For 3D rendering, 2D apps (Photoshop, Flash MX), and media encoding, even a 2.0 GHz P-M cannot match the performance of a 3.2 GHz P4.

The datasheets provided by Intel indicate that the Celeron M silicon has exactly the same dimensions as the Pentium M/Core Duo.
The distinction between the Celeron M vs Pentium M/Core Duo is that the cache and core is reduced by one-half. But users shouldn't worry too much about the smaller cache. This is due to Pentium M architecture has between 10-12 stages (unconfirmed), making it less dependent on the large cache size (as did the earlier P2 and P3, Celeron kicked ass.)
Now, there are 3 types of Celeron M:
Banias 130nm Core (900 MHz - 1.5 GHz with 512 KB L2 Cache)
Dothan 90nm Core (900 MHz - 1.7 GHz with 1 MB L2 Cache)
Yonah 65nm Core (1.06 GHz - 2.0 GHz with 1 MB L2 Cache, SSE3)
About performance, the Celeron M will outperform the P4-M brother by a good 35-40%. So the fastest 1.5 GHz equates to P4-M 2 GHz. The Banias core is about 5% slower than the Dothan. So multiply your chip by 1.4 for the Dothan, and 1.33 for the Banias.
By no means, the Celeron M is a speedster in this category, but it's a very cool chip and derived from the Pentium M/Core Duo, making it inherently low-power consumption. Although there are 2 draw backs.
#1) No SpeedStep (processor will always run at max. clock speed).
#2) No advanced power management.
These two combines weakens the Pentium M/Core Duo basic platform, long battery life. But user must beware that even with these two drawbacks, the inherent architecture still give its better battery life than the P4-M.
