How Graphics Cards Work"

How Graphics Cards Work"
The images you see on your monitor are made of tiny dots called pixels. At most common resolution settings, a screen displays over a million pixels, and the computer has to decide what to do with every one in order to create an image. To do this, it needs a translator -- something to take binary data from the CPU and turn it into a picture you can see. Unless a computer has graphics capability built into the motherboard, that translation takes place on the graphics card. A graphics card's job is complex, but its principles and components are easy to understand. In this article, we will look at the basic parts of a video card and what they do. Think of a computer as a company with its own art department. A graphics card works along the same principles. Creating an image out of binary data is a demanding process. The graphics card accomplishes this task using four main components: Next, we'll look at the processor and memory in more detail.

50 Kick-Ass Websites You Need to Know About It's time to update the entries in your browser's links toolbar. But with recent estimates putting the size of the internet at well more than 100 million distinct websites, it's getting harder and harder to get a handle on all the great stuff that's out there. That's why we've compiled this list. And unlike some lists you may have seen, which try to name the very "best" websites, but end up just telling you a lot of stuff you already know, we've chosen instead to highlight 50 of our favorite sites that fly under most people's radar. You might have heard of some of these sites, but we'll bet you haven't heard of all them. See What Can Be Done with 4 Kilobytes If you’re any kind of nerd at all, you probably know about the demoscene, where talented programmers create complex videos rendered in real-time, stored in incredibly small files. But what if you just want to see what all the fuss is about without actually downloading and running an executable?

Understanding Chipsets: What is a Chipset, Anyway? - Gamers Nexus - Your hub for gaming hardware, news, PC builds, and reviews Known for having the coolest-sounding naming scheme in computing, chipsets operate at the core of every build we do here at GN -- by this point, all of you know the basics: P67 is good, Z68 is better, X79 (SB-E) is expensive; the 970 is good, the 990X is great, and AM3+'s 990FX is expensive (sort of). Great, so we have an idea of what to get relative to other chipsets, but that doesn't mean much. That's about as useful as knowing "DDR3 is better than DDR2," without truly knowing why. It's brochure knowledge. As we did with our GPU dictionary and SSD dictionary, this chipset guide will help explain what, exactly, a chipset is responsible for and what you should look for in future editions. This helps keep everyone on the cutting edge as new technology is announced and, better still, helps you actually understand what is needed, not just recommended.

How to Hunt Elephants MATHEMATICIANS hunt elephants by going to Africa, throwing out everything that is not an elephant, and catching one of whatever is left. EXPERIENCED MATHEMATICIANS will attempt to prove the existence of at least one unique elephant before proceeding to step 1 as a subordinate exercise. PROFESSORS OF MATHEMATICS will prove the existence of at least one unique elephant and then leave the detection and capture of an actual elephant as an exercise for their graduate students. COMPUTER SCIENTISTS hunt elephants by exercising Algorithm A: Go to Africa. EXPERIENCED COMPUTER PROGRAMMERS modify Algorithm A by placing a known elephant in Cairo to ensure that the algorithm will terminate. ASSEMBLY LANGUAGE PROGRAMMERS prefer to execute Algorithm A on their hands and knees. DATABASE ADMINISTRATORS do not need to go out and capture elephants when they can retrieve them simply with an ad hoc query: STATISTICIANS hunt the first animal they see N times and call it an elephant.

Sciency stuff Best Gaming CPUs For The Money: February 2012 : Best Gaming CPUs For The Money, February Updates In this month's update, we discuss the new A4-4020 and A4-6420K APUs, AMD's low-power, entry-level Socket FS1b-based platform, and how it will stack up against Intel's counterpart, Bay Trail-D. We also report on a handful of price changes in the market. If you don’t have the time to research benchmarks, or if you don’t feel confident enough in your ability to pick the right processor for your next gaming machine, fear not. We at Tom’s Hardware have come to your aid with a simple list of the best gaming CPUs offered for the money. March Updates: The past month was quiet in the processor market, with a few minor exceptions. Also coming from AMD, the company is re-branding its low-power Socket FS1b interface for Kabini-based APUs as the AM1 platform. This should be interesting competition for Intel's Bay Trail-D platform, which features soldered-down SoCs rather than AMD's socketed APUs. As for pricing moves, there's not much to report. Some Notes About Our Recommendations

AMD Or Intel: Which Offers Better Gaming Performance? : Picking A Sub-$200 Gaming CPU: FX, An APU, Or A Pentium? That’s a lot of data to digest, so let’s distill it down by averaging out performance in all benchmarks relative to AMD's A4-3400. Again, we sort by minimum frame rate because we're calling that statistic more important than the average. It's the best way to quantify the benefit of a powerful-enough processor, representing its ability to stand up to a worse-case scenario. If the above chart presents any surprises, they'd be the dual-core Pentium G630 and G860, which perform incredibly well, matching up to AMD's former Phenom II X4 955 flagship. To that end, we were hoping to see the Llano-based APUs succeed the inexpensive Athlons under $100, impressing gamers with discrete graphics cards on strict budgets. With the sub-$100 Pentiums performing so well, Intel's $125 Core i3-2100 easily beats more expensive Phenom II and FX models. The biggest flaw with Intel's low-end offerings is that the Pentium family limits you to dual-core configurations.

Intel Reveals More Details of Ivy Bridge Variants at ISSCC Ubuntu for Android is making an appearance next week at Mobile World Congress. On Tuesday Canonical revealed Ubuntu for Android, a release the company says will bring a full desktop computing experience to a docked Android smartphone. But don't expect to install this software on your current device (legally): it will only be available on new devices provided by participating manufacturers. Canonical has reportedly combined the Ubuntu architecture with Google's 2.3 "Gingerbread" AOSP build at the kernel level. As the name indicates, it won't be out to compete with Apple's iOS, Microsoft's Windows Phone or even Android itself as a standalone OS, but serve as a "value-add" service that Canonical hopes will reduce the number of devices carried by Android consumers. "Why carry two devices, when you could carry only one?" "Manage and view photos stored on your smartphone using the Ubuntu Gallery application.

Video Connectors Tutorial VGA is the traditional plug used to connect your PC to video monitors. It is also one option to connect your PC to video projectors and digital TV sets (HDTVs). This connection offers a better video quality than component video, S-Video, and composite video because it uses an independent wire for each video signal: red, green, blue, horizontal sync, and vertical sync. click to enlargeFigure 23: VGA connector on a video card click to enlargeFigure 24: VGA cable of a video monitor click to enlargeFigure 25: VGA connector on an HDTV set 64 Raspberry Pis + Legos = Supercomputer Computer engineers combine 64 Raspberry Pis and a Lego-built framework to create a DIY supercomputer. Earlier this year, Raspberry Pi lured the world in with the scent of a $35, linux-powered mini-PC. Since its release, the device has been used for a number of creative purposes. Taking good notice of Moore's Law, the team realized the cost of creating a supercomputer has dropped exponentially over the years, allowing them to create one for as little as £2,500. Led by professor Simon Cox, the team has kindly created a detailed guide for anybody looking to create their own Raspberry Pi supercomputer. Contact Us for News Tips, Corrections and Feedback
