Intel P45

Intel P45 is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Intel P45 rather than just read about it. In short: The P45 Express (codenamed Eaglelake) is a mainstream desktop computer chipset from Intel released in Q2 2008. The first mainboards featuring the P45 chipset were shown at CeBIT 2008.

Key takeaways

  • Intel P45 belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Intel P45 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Intel P45 from memory before moving on to harder problems.

Reference excerpt

The P45 Express (codenamed Eaglelake) is a mainstream desktop computer chipset from Intel released in Q2 2008. The first mainboards featuring the P45 chipset were shown at CeBIT 2008. The P45 Express chipset supports Intel's LGA 775 socket and Core 2 Duo and Quad processors. It is a 65 nm chipset, compared to the earlier generation chipsets (P35, X38, X48) which were 90 nm.

Features 1333/1066/800 MT/s front-side bus (FSB), most motherboard manufacturers claim support up to 1600 MT/s. PCI Express 2.0, 1 ×16 or 2 ×8 in CrossFire configuration. Dual-channel DDR2 memory up to 16 GiB addressable memory; officially up to 800 MHz, most motherboard manufacturers claim support up to 1200 MHz Dual-channel DDR3 memory up to 8 GiB addressable memory; officially up 1066 MHz, most motherboard manufacturers claim support up to 1333 MHz ICH10 / ICH10R southbridge Supports 45 nm processors

Worked examples

Example 1 — a first encounter with Intel P45

Start with the simplest possible case. Write down what Intel P45 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Intel P45 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Intel P45 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Intel P45

In research
Intel P45 appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Intel P45 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Intel P45 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer hardware stubs, Intel chipsets, so understanding it makes those chapters shorter.
In everyday life
Look for Intel P45 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Intel P45 in simple terms?

The P45 Express (codenamed Eaglelake) is a mainstream desktop computer chipset from Intel released in Q2 2008. The first mainboards featuring the P45 chipset were shown at CeBIT 2008.

Why does Intel P45 matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Intel P45?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Intel P45.
