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.
There is no "Pentium R" processor. Knowing this, the biggest difference is that the Pentium III exists and the other does not.
Nothing, a Pentium Processor, or any other processor for that matter, is merely a brand name for different microprocessors.
T4200 has Enhanced Intel® Speedstep Technology which the celeron doesn't. http://ark.intel.com/Product.aspx?id=37251 vs http://ark.intel.com/Product.aspx?id=41498 Not having speedstep on an laptop will be bad for your battery consumption.
Sort of. The processor is an Intel Coppermine-core processor that runs at 733 MHz. It is soldered onto the motherboard in BGA2 fashion, similar to that found in many older Pentium III and Celeron laptops. The processor can't be considered a Pentium III because it has half the L2 cache of a normal Pentium III at that speed and FSB. It's not a quite a Celeron either, though, since no other Celeron in that layout had that high an FSB (133 MHz in the Xbox vs. 100 MHz for other mobile Celerons. It thus sits somewhere in between in terms of performance.Architecturally, it is no different than a Pentium III, though. Linux applications written for the Pentium III can run without modification on the Xbox.
There is no Pentium 5 processor. The mainstream (non-budget) Pentium line ends with the Pentium D, which is essentially a dual-core Pentium 4. The Core Solo, Core Duo, Core 2 Duo, and Core 2 Quad all have a very different architecture from the Pentium 4.
Celerons have a smaller amount of L2 cache.
The Intel Pentium line encompasses many processors of many different architectures ranging from the original Pentium Processor of 1994 up to the Core 2 Duo based Pentium simply called the "Pentium". The Intel Pentium used to be Intel's flagship processor. Recently this position has been taken by the Core 2 Duo and Core i7. The Pentium now is reduced to a budget processor that offers lower performance but also lower cost.
The Pentium D is essentially a rebranded and double-cored version of the Pentium 4. The Core 2 Duo is a much more efficient and powerful processor.
pentium 4 more faster
4004 8008 8086 and series go on 80286 80386 80486 Pentium 1 Pentium 2 Pentium 3 Pentium 4 Dual core Core 2 duo Core 2 Quad Upto CoreI7 So basically in a long time period Pentium 4 is an improvement on 8085 and basically today micro code of all these processor is of 8085
x86 refers to any processor that is instruction-compatible with the Intel 8086 and higher. This includes the Pentium, Pentium II, Celeron, Pentium III, Pentium 4, Pentium D, Core Duo, Core 2 Duo, Core i7, Atom, AMD Athlon, Sempron, Athlon 64, Phenom, and Geode. x64 is often used to refer to any x86 processor that has 64-bit extensions (x86-64). These include the AMD Athlon 64, late models of the Pentium 4, Pentium D, Core 2 Duo, Phenom, and certain Geode processors. x32 is a retcon of the x64 term to apply to either 32-bit only processors or programs.
On the Pentium II, the L2 cache is integrated into the processor packaging, rather than on the motherboard. This allows the L2 to be accessed much faster, and improving overall performance.
