How to upgrade your BIOS
Date Issued: 21st Oct 2008

This How-2 Guide explains what BIOS is and how it can be upgraded to the latest revision. BIOS, which stands for Basic Input/Output System, is a integral software program that comes pre-loaded with your computer. Its purpose is to initially identify computer hardware and prepare the system to run other software such as operating systems.

Cores
Date Issued: 20th Oct 2008

Over the course of the last year or so we’ve seen GHz become less of a focus when it comes to processors. Instead, we’re seeing a shift towards processors that do more work per clock, have larger caches, are more power efficient, and of course we’ve seen dual-core processors hit the market. So what is dual-core all about, and how does it weigh up compared to single-core?

CPU Codes
Date Issued: 20th Oct 2008

It’s been a long time since MHz were the only part of a CPU’s specification that concerned people. Manufacturers take different approaches to CPU design, even when using the same architecture. That means for example, at the same clock speed, an Intel and AMD processor will deliver different performance.

Chipsets
Date Issued: 20th Oct 2008

What makes a PC tick? Is it the processor, graphics card, RAM, or a plethora of other peripherals. It’s all those and more, but none would be much use without a means of connecting said components in an efficient manner. That’s where your humble motherboard comes in. Its job is to ensure that all devices can communicate correctly, and the beating heart of any motherboard is the chipset it’s based upon.

AMD 64 Processors
Date Issued: 20th Oct 2008

This TekSpek explains what AMD’s AMD64 CPU instruction set architecture (ISA) is, shows what CPUs implement it from both AMD and Intel, and explains what software is available to run on those 64-bit consumer processors.

Architecture wars
Date Issued: 2nd Nov 2006

Intel’s Core 2 Duo is now slugging it out against AMD’s Socket AM2 Athlon 64s with DDR2 memory support. So what is next on the roadmap from the two chip-vending foes?
