The general trademark of a manufacturer by which the consumer knows its products. A manufacturer can have multiple brand names. Some manufacturers license their brand names to other producers.
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.
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.
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.
Article code :
The brand's unique identifier for a product. Multiple product codes can be mapped to one mother product code 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.
Data-sheet quality: created/standardized by Icecat
The quality of the data-sheets can be on several levels:
only logistic data imported: we have only basic data imported from a supplier, a data-sheet is not yet created by an editor.
created by Intel: a data-sheet is imported from an official source from a manufacturer. But the data-sheet is not yet standardized by an Icecat editor.
created/standardized by Icecat: the data-sheet is created or standardized by an Icecat editor.

Long product name Intel Pentium 640:
The short editorial description of Intel Pentium 640
Intel® Pentium® 4 Processor 640 supporting HT Technology (2M Cache, 3.20 GHz, 800 MHz FSB)

Marketing text Intel Pentium 640

The official marketing text of Intel Pentium 640 as supplied by the manufacturer
With a computer based on the Intel® Pentium® 4 Processor 6XX sequence supporting Hyper-Threading Technology, there are endless possibilities for work, play, creating, learning and being entertained. The processor capabilities and the features of a compatible Intel® Express Chipset combine for a dynamic and powerful desktop computer for the home, office and classroom.

Intel® Hyper-Threading Technology
Intel® Hyper-Threading Technology (Intel® HT Technology) delivers two processing threads per physical core. Highly threaded applications can get more work done in parallel, completing tasks sooner.

Intel® 64
Intel® 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software. Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.

Enhanced Intel SpeedStep® Technology
Enhanced Intel SpeedStep® Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep® Technology switches both voltage and frequency in tandem between high and low levels in response to processor load. Enhanced Intel SpeedStep® Technology builds upon that architecture using design strategies such as Separation between Voltage and Frequency Changes, and Clock Partitioning and Recovery.

Execute Disable Bit
Execute Disable Bit is a hardware-based security feature that can reduce exposure to viruses and malicious-code attacks and prevent harmful software from executing and propagating on the server or network.

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 4
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.
3.2 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).
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.
Socket T (LGA 775)
Component for*
What this product is used as a part of (component for).
Processor lithography*
The process which is performed by the processor e.g. CPU (Central Processing Unit).
90 nm
Plastic or metal shell/container for components.
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).
800 MHz
Processor series
Intel Pentium 4 600 series supporting Hyper-Threading Technology
The model number for the processor in a computer.
Processor threads*
Processor operating modes*
Operating modes for the processors that place restrictions on the type and scope of operations for certain processes run by the CPU. This design allows the operating system to run with more privileges than application software.
