Brand:
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.
Intel
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 840 (2M Cache, 3.20 GHz, 800 MHz FSB)
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.

The official marketing text of Intel Pentium 840 3.2GHz 2MB L2 Box processor as supplied by the manufacturer
An Intel® Pentium® D processor–based PC delivers an extra powerful gear when you need it. Accomplish more while running multiple applications, such as editing video while downloading music.

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.

Idle States
Idle States (C-states) are used to save power when the processor is idle. C0 is the operational state, meaning that the CPU is doing useful work. C1 is the first idle state, C2 the second, and so on, where more power saving actions are taken for numerically higher C-states.

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.

In our last review concerning Intels CPUs, we had tested the flagship Single-core processor from Intel, the 3.73GHz Extreme Edition which was also extremely expensive. This time, we have in our hands the 840 which is a Dual-Core CPU, running at 3.20G...
Bottom line With the new Dual-Core series from both Intel and AMD, a new era in processors has started. They are already available at varying speeds as well as prices. It is rather interesting to put them to the test and compare them against the single core gene...

Processors have evolved for years now under the pretext that clock speed and IPC were the two keys to boosting performance. Intel elongated the pipeline of its Pentium 4 and went for frequency, while AMD proved with K8 that IPC is an equally potent var...

Its time for another processor review here at Neoseeker. This time we are taking a look at the Intel 840 D - a mid range dual core offering; we hope to look at its newer 65nm 940 brother in the near future. The 840 D has the following features: - 800M...
Bottom line Yes, Virginia, dual cores on the Intel does help. The Intel 840 D fared quite well in dual core tests, especially where the applications did not need to saturate the FSB with memory reads/writes; for compute bound applications you can get nearly twice...
