A checksum is a number, in the form of a binary or hexadecimal value, that's been derived from a data source. The important bits to know are that it's typically much smaller than the source, and it's also almost entirely unique.
Computer technology is no strange to acronyms: CPU, RAM, SSD, to name but a few. Ever so often, new ones appear on the scene in the never-ending quest to improve the capabilities of our computing devices. Today we'll explain processor instruction set extensions MMX, SSE, and AVX.
#tbt By far the most common types of display panels used on PC monitors are TN, IPS and VA. We're sure you've heard these terms before if you've researched monitors to purchase, and to be clear, the type of panel is a key piece of information that reveals a lot about how the monitor will behave and perform.
For 25 years, the USB port has been a faithful old friend, connecting and powering our everyday gadgets and peripherals. But how exactly does it that happen? Welcome to our explainer on the inner workings of USB, and a look at how it's managed to survive for so long when others have come and gone.
With technology advancing so rapidly around us, sometimes misconceptions can work their way into our common understanding. In this article, we'll take a step back and go over some of the most common things people get wrong when talking about computer hardware.
Wi-Fi is set to get better and faster. While plenty of routers are already available with chips using draft specifications, 802.11ax Wi-Fi was not finalized until late 2019, ushering in a wave of updated devices touting new wireless capabilities that will contribute toward next-generation networks with more speed and less congestion.
Nvidia has been making graphics chips that feature extra cores, beyond the normal ones used for shaders. Known as tensor cores, these mysterious units can be found in thousands of system, but what exactly are they and what are they used for? Today we'll explain what a tensor is and how tensor cores are used in the world of graphics and deep learning.
Every once in a while, a video game is made that becomes part of the industry's history. For PC gamers, there's one title that's almost legendary thanks to its incredible, ahead-of-its-time graphics and ability to grind PCs into single digit frame rates. Join us as we take a look back at Crysis and see what made it so special.
Machine learning (ML) is the study of computer systems that automatically improve with experience, a hot topic in the last few years, but a concept that's been around for decades. IBM programmer and AI pioneer Arthur Samuel coined the term "machine learning" in 1952.
You've just bought a new CPU and it seems to run pretty cool, so you try a bit of overclocking. The GHz climbs higher and higher, it's surely not supposed to be like this? You rush to the internet to share your excitement of hitting the silicon jackpot, and within a few posts, somebody proclaims that you've got yourself a binned chip. But what is it?
The vast majority of visual effects you see in games today depend on the clever use of lighting and shadows -- without them, games would be dull and lifeless. In this fourth part of our deep look at 3D game rendering, we'll focus on what happens to a 3D world alongside processing vertices and applying textures. It once again involves a lot of math and a sound grasp of the fundamentals of optics.
The first 3D graphics cards appeared 25 years ago and since then their power and complexity have grown at a scale greater than any other microchip found in a PC. In going from one million to billions of transistors, smaller dies, and consuming more power, the capabilities of these behemoths is immeasurably greater, but what can we learn about efficiency?
Without properly managing heat, our electronic systems would destroy themselves or conversely, we'd be severely limiting our computing capabilities. This article will touch on the basic science of heat, how and why it is generated in electronics, and the various methods we have developed to control it.
#ThrowBackThursday We all think of the CPU as the "brains" of a computer, but what does that actually mean? What is going on inside with the billions of transistors to make your computer work? In this new four-part mini series we'll be focusing on computer hardware design, covering the ins and outs of what makes a computer work.
Video game physics are something that we often take for granted. Programming physics into a game can be as simple as one or two routines, or as complex as requiring a separate physics engine to handle the computations. In this article we'll delve into the specifics of rigid body and soft body physics in games.
Inside the latest graphics cards lies a large graphics processor, packed with billions of transistors, all running at clock speeds unthinkable a decade ago. Welcome to our architectural comparison of the newest GPUs from AMD and Nvidia.
In this third part of our deeper look at 3D game rendering, we'll be focusing what can happen to the 3D world after the vertex processing has done and the scene has been rasterized. The majority of the visual effects seen in games today are down to the clever use of textures -- without them, games would dull and lifeless. So let's get dive in and see how this all works!
In the world of computer chips, bigger numbers are often better. More cores, higher GHz, greater FLOPs, all desired by engineers and users alike. But there is one measure that's hot news right now and the smaller it is, the better. Let's take a journey into the world of process nodes, to find out more.
In this second part of our deeper look at 3D game rendering, we'll be focusing what happens to the 3D world after all of the vertex processing has finished. We'll need to dust off our math textbooks again, grapple with the geometry of frustums, and ponder the puzzle of perspectives. We'll also take a quick dive into the physics of ray tracing, lighting and materials -- excellent!
Despite continuous improvements, processors haven't had industry shifting advancements for a long time. Yes, transistors are smaller, chips have gotten faster, and performance has increased hundredfold, but we're starting to see diminishing returns... learn what 3D integration, FPGAs, and near memory computing are all about.
You're playing the latest Call of Mario: Deathduty Battleyard on your perfect gaming PC. You're looking at a beautiful 4K ultra widescreen monitor, admiring the scenery and detail. Ever wondered just how those graphics got there? Curious about what the game made your PC do to make them? Welcome to our 101 in 3D game rendering: a beginner's guide to how one basic frame of gaming goodness is made.
