Clock speed is only a useful comparison of speed when two processors share the same architecture. AMD and Intel processors have different internal architectures. At various points in time, one manufacturer had a more efficient architecture than the other, thus providing better performance at a lower clock speed. As of Q2 of 2009, Intel currently offers more efficient processors.
As the Celeron D is a product line and not a specific processor, there is no specific comparable processor. Depending on the model. the Celeron D is comparable in performance to various Athlon 64, Athlon XP, and Sempron processors.
There are lots of benchmarks. Without knowing what benchmark you wanted to test on the processor, it would be impossible to give you its score. Even then, the benchmark is only useful if you have the score from other processors to compare it to.
ARM is a processor architecture that incorporates a few different types of microprocessor that isn't built on the x86 protocol. They are called processors because they ARE processors.
There are thousands of different types of processors in the world. There are processors ranging from computers to the human brain.
Superscalar processors have a main processor that can take only one command at a time. It has direct connections to the secondary systems of the processor that feeds information right into subsystems to execute specific commands and output information separate. There is only one type of superscalar processor but there are scalar processors and vector processors.
VIA (owner of Cyrix processors)
No. Xeon processors use different chipsets and sockets, thus they are not interchangeable with mainstream processors.
There aren't really kinds of processors, they have different architectures. There are thousands with the most popular kind of architecture in processors are x86/x64 and ARM.
The best comparison site for computer processor units (CPU) is CPU Benchmark. That site enables direct comparisons, but other sites like Consumer Reports also have less detailed comparisons as well.
A variant when it comes to processors refers to related models of processors. For example, a variant of the Intel Core i3 processor is the Intel Core i5 processor.
Intel are probably the best computer processors in the market today. There are different types of Intel processors but each is tried and tested and reliable.
A processor family is a group of processors that share similar features and construction. Which processors belong to a family is determined by the CPU manufacturer.
