Intel
Product family:
The product family is a generic trademark of a brand to indicate a very wide range of products, that can encompass multiple categories. We include product family in the Icecat product title.
Pentium
Product series:
Product series is a brand's indication, often indicated by round numbers like 3000, that identifies a group of products within one category that are technically very similar. We don't include product serie in the Icecat product title on a product data-sheet to avoid confusion.
D
Product name:
Product name is a brand's identification of a product, often a model name, but not totally unique as it can include some product variants. Product name is a key part of the Icecat product title on a product data-sheet.
Intel® Pentium® D Processor 805 (2M Cache, 2.66 GHz, 533 MHz FSB)
Product code :
The brand's unique identifier for a product. Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical. We map away wrong codes or sometimes logistic variants.

The Central Processing Unit (CPU) or (micro) processor is the part of a computer where most calculations take place. In terms of computing power, the processor is the most important element of a computer system, so the performance of a computer is highly dependant on the performance of the processor. For quite some time the performance of a processor has been determined by the number of MHz the clock speed was, but nowadays clock speed doesn\'t have so much to do with the speed of the processor anymore. One of the best ways to compare different kinds of processors, is to look up benchmarks on the internet. Please be careful to buy a processor that is compatible with your motherboard, i.e. fits in the right socket.

Processor
Processor family *
A family of processors is a group of processors produced by one company over a short period of time e.g. Intel Pentium processors.
Intel® Pentium® D
Processor frequency *
The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions. Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform.
2.66 GHz
Processor cores *
The number of central processing units ('cores') in a processor. Some processors have 1 core, others have 2 (e.g. Intel Core Duo) or more (e.g. the Intel Xeon E7-2850 has 10 cores).
2
Processor socket *
Mechanical component(s) that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the processor to be replaced without soldering.
LGA 775 (Socket T)
Processor lithography *
The process which is performed by the processor e.g. CPU (Central Processing Unit).
90 nm
Box *
Plastic or metal shell/container for components.
Yes
Processor front side bus
A computer communications interface used to connect the processor to the rest of the computer, except the cache (and possibly other processors).

Processor model *
The model number for the processor in a computer.
805
Processor threads *
