The "M" stands for Mobile as in laptop, notebook, etc. computer. Consumes less power, generally uses lower voltages, and produces less heat.
No. The Celeron and Pentium Ms predate the Intel Core line by several years.
There are a number of references that a person can use to find a computer with an Intel Celeron M chip. For instance, a person can refer to Tablet PC Review, Eurogamer, or Amazon for more specifics concerning where to find a computer with an Intel Celeron M chip.
Celeron refers to a line of processors from Intel. They are low-cost counterparts of Pentium II, III, 4, M, and D processors. They differ mainly in the amount of L2 cache. Celerons have a smaller L2 cache, which is basically a buffer in the CPU to avoid slowdown. With a smaller L2 cache, Celerons perform slightly worse in some processor-intensive applications.
With the dual core you can process more, but with the pentium at a slightly higher rate, I'd go with the celeron however.
Check the specs on your motherboard. If you don't have the specs, go to the manufacturers website and look up the model. You should be able to find them there and maybe even download a pdf document containing them to keep for reference.
AnswerA Celeron was a cost-reduced version of an Intel Pentium II, Pentium III, Pentium 4, Pentium D, or Pentium M. It was made cheaper by not including as much L2 cache (the first ones had none at all), and was aimed primarily at the lower-end market.
The AMD Turion 64 MK38 processor out performs the Intel Celeron M 440 processor due to its multiple cores and higher clock speed. However, the Celeron M 440 uses up less power and produces less heat.
LGA 775 processors are supported by LGS 775 sockets. Most, if not all, Intel processors are LGA 775, and almost no, if any, AMD processors are LGA 775. At www.newegg.com look up your processor and check the specifications to see what socket type it is.
Pentium M stands for Mobile and generally is seen in Laptops. Core2Duo is the latest CPU design from Intel (with Xeon Quad) - it allows 2 cores to be mounted on the same chip. It is virtually like having 2 cpus in parallel. Great for multitasking operations.
Possibly. "Celeron" doesn't refer to any particular processor. They are cost-reduced versions of the Intel Pentium II, Pentium III, Pentium 4, Pentium M, and Core 2 Duo. Assuming that your Celeron is based on a processor that is faster than the Pentium III, you shouldn't have any problems. If yours is based on the Pentium III, check the clock speed. A 1.2 GHz Celeron, for instance, is probably fast enough for a game that requires a 1 GHz Pentium III.Other factors, such as the graphics card of your system, may also be important.
A Celeron is any of a large number of different budget x86 microprocessors produced by Intel and marketed as a budget/value CPU line. The Celeron family complements Intel's higher-performance (and more expensive) Pentium CPUs family. Introduced in April 1998, the first Celeron was based on the Pentium II core. Later versions were based on the Pentium III, Pentium 4, and Pentium M. These processors are suitable for most applications, but their performance is somewhat limited when it comes to running intense applications, such as cutting edge games or graphical modeling programs, especially when compared to that of their high-end counterparts. Centrino, a platform-marketing initiative from Intel, covers a particular combination of CPU (mainly Pentium M), mainboard chipset and wireless network interface in the design of a laptop personal computer I personally recommend an AMD processor, not one of Intel's. Processors such as the Sempron and Athlon are very nice processors in terms of money and performance compared to one like the Core 2 Duo option.
The sockets are different, so by default, you cannot use them in a desktop. There are adapters for Pentium M and Celeron M chips to be used in Socket 478 motherboards. You can purchase motherboards specifically made to support mobile processors as well.
