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.
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.
Category :
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 product data-sheet 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 551:
The short editorial description of Intel Pentium 551
Intel® Pentium® 4 Processor 551 supporting HT Technology (1M Cache, 3.40 GHz, 800 MHz FSB)

Marketing text Intel Pentium 551

The official marketing text of Intel Pentium 551 as supplied by the manufacturer
On 90 nm Process in 775-land LGA Package and supporting Intel® Extended Memory 64 Technology

The Intel® Pentium®4 processor on 90 nm process in the 775-land package is a follow on to the Pentium 4 processor in the 478-pin package with enhancements to the Intel NetBurst® microarchitecture. The Pentium 4 processor on 90 nm process in the 775-land package uses Flip-Chip Land Grid Array (FC-LGA4) package technology, and plugs into the 775LGA socket. The Pentium 4 processor in the 775-land package, like its predecessor, the Pentium 4 processor in the 478-pin package, is based on the same Intel 32-bit microarchitecture and maintains the tradition of compatibility with IA-32 software.

Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families.

Intel® Extended Memory 64 Technology (Intel® EM64T) requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software configurations. See www.intel.com/info/em64t for more information including details on which processors support EM64T or consult with your system vendor for more information.

Requires an Intel® Hyper-Threading Technology (Intel® HT Technology)-enabled system, check with your PC manufacturer. Performance will vary depending on the specific hardware and software used. Not available on the Intel® Core™ i5-750. For more information, including details on which processors support HT technology.

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.
3.4 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 4 500 series supporting Hyper-Threading Technology
Processor model*
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.
