Skip to the next section for an in-depth look at the process.&nbsp;<\/p>\n\n\n\n<p>The CPU in your computer can solve just about any type of mathematical problem. CPU circuits use more components to deal with many kinds of tasks. They take up more space, generate more heat, and aren\u2019t as elegantly designed as a circuit built for a single job.&nbsp;<\/p>\n\n\n\n<p>With hardware acceleration, a special integrated circuit or microprocessor does one specific task or a narrow set of related jobs. The circuit\u2019s design is not wasted on anything else, and this provides a significant performance advantage.&nbsp;<\/p>\n\n\n\n\t\t\t<div class=\"wp-block-image\">\n\t\t\t<figure class=\"aligncenter size-large\"><a href=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/2.-CPU.jpg\" data-lasso-id=\"15925\"><img loading=\"lazy\" decoding=\"async\" width=\"680\" height=\"383\" src=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/2.-CPU.jpg\" alt=\"\" class=\"wp-image-51066\" srcset=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/2.-CPU.jpg 680w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/2.-CPU-300x169.jpg 300w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/2.-CPU-610x344.jpg 610w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/2.-CPU-80x45.jpg 80w\" sizes=\"auto, (max-width: 680px) 100vw, 680px\" \/><\/a><\/figure>\n\t\t\t<\/div>\n\t\t\n\n\n<p>Sometimes that hardware is built into the CPU itself. Most modern CPUs have dedicated internal sections that accelerate specific types of math used for tasks such as <a href=\"https:\/\/helpdeskgeek.com\/the-most-common-video-formats-and-codecs-explained\/\" target=\"_blank\" rel=\"noopener\" data-lasso-id=\"15926\">video encoding<\/a> and <a href=\"https:\/\/helpdeskgeek.com\/how-secure-is-the-military-grade-aes-encryption-algorithm\/\" target=\"_blank\" rel=\"noopener\" data-lasso-id=\"15927\">encryption<\/a>.<\/p>\n\n\n\n<p>In short, hardware acceleration means giving a specific job to a unique piece of hardware that\u2019s a jack of one trade and rocks at it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Are the Benefits of Hardware Acceleration?<\/h2>\n\n\n\n<p>How does hardware acceleration benefit the application you\u2019re using? It often depends on the type of hardware and the type of acceleration, but the usual benefits apply to most situations.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Hardware acceleration greatly improves performance. Your application will run more smoothly, or the application will complete a task in a much shorter time.<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>It frees up your CPU to do other things leading to<em> <\/em>improved system performance. The CPU can offload work to the specialized hardware and then get on with, for example, running video games simultaneously with streaming videos or using an application like <a href=\"https:\/\/www.online-tech-tips.com\/how-to-make-a-discord-server\/\" target=\"_blank\" rel=\"noopener\" data-lasso-id=\"15928\">Discord<\/a>.<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>Hardware acceleration can be crucial for battery-powered devices. It\u2019s why your smartphone or tablet can play video for such a long time without tanking your battery. A small specialized chip almost always uses less power than a large, complex CPU.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Are There Downsides to Hardware Acceleration?<\/h2>\n\n\n\n\t\t\t<div class=\"wp-block-image\">\n\t\t\t<figure class=\"aligncenter size-large\"><a href=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/4-Error.jpg\" data-lasso-id=\"15929\"><img loading=\"lazy\" decoding=\"async\" width=\"680\" height=\"383\" src=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/4-Error.jpg\" alt=\"\" class=\"wp-image-51067\" srcset=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/4-Error.jpg 680w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/4-Error-300x169.jpg 300w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/4-Error-610x344.jpg 610w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/4-Error-80x45.jpg 80w\" sizes=\"auto, (max-width: 680px) 100vw, 680px\" \/><\/a><\/figure>\n\t\t\t<\/div>\n\t\t\n\n\n<p>In general, hardware acceleration is something that you\u2019ll want to leave on, but there are some cases where it can be a drawback.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Hardware acceleration often causes instability. Despite being slow, CPUs tend to be highly reliable. For example, there&#8217;s little point in having hardware acceleration speed up video exports and then have the process crash before it finishes.<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>Hardware acceleration is inflexible to new developments. For example, you may have hardware acceleration in your computer for a specific video encoding method, but if something better comes along you\u2019ll have to buy new hardware to support it.&nbsp;<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>The type of hardware acceleration your system supports might not offer the best results. So if you favor quality over speed, it would be better to let the CPU handle the work in some cases. For example, if you don\u2019t have hardware support for HEVC encoding but want its quality advantages over the H.264 CODEC, you\u2019ll have to rely on CPU-based encoding.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Where Can I Use Hardware Acceleration?<\/h2>\n\n\n\n<p>There are too many forms of hardware acceleration available to list them all here, but here are a few common ones that you will encounter as an average computer user.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Browser Hardware Acceleration<\/strong><strong><\/strong><\/h4>\n\n\n\n\t\t\t<div class=\"wp-block-image\">\n\t\t\t<figure class=\"aligncenter size-large\"><a href=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/5-Browser.jpg\" data-lasso-id=\"15930\"><img loading=\"lazy\" decoding=\"async\" width=\"680\" height=\"383\" src=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/5-Browser.jpg\" alt=\"\" class=\"wp-image-51068\" srcset=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/5-Browser.jpg 680w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/5-Browser-300x169.jpg 300w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/5-Browser-610x344.jpg 610w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/5-Browser-80x45.jpg 80w\" sizes=\"auto, (max-width: 680px) 100vw, 680px\" \/><\/a><\/figure>\n\t\t\t<\/div>\n\t\t\n\n\n<p>Web browsers can be surprisingly CPU-heavy applications.

These processors consist of hundreds or thousands of simple small processors that all work in parallel.&nbsp;<\/p>\n\n\n\n<p>This makes them ideal for certain types of data crunching that need to be run through an algorithm. GPUs are designed this way because rendering graphics involves processing pixel values in parallel. So your GPU determines what each of the millions of pixels on the screen should look like at the same time. It turns out that deep learning and data mining applications also benefit from this approach to computation.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Ray Tracing and Machine Learning Acceleration<\/strong><strong><\/strong><\/h4>\n\n\n\n\t\t\t<div class=\"wp-block-image\">\n\t\t\t<figure class=\"aligncenter size-large\"><a href=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/8-Ray-Tracing.jpg\" data-lasso-id=\"15936\"><img loading=\"lazy\" decoding=\"async\" width=\"680\" height=\"383\" src=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/8-Ray-Tracing.jpg\" alt=\"\" class=\"wp-image-51071\" srcset=\"https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/8-Ray-Tracing.jpg 680w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/8-Ray-Tracing-300x169.jpg 300w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/8-Ray-Tracing-610x344.jpg 610w, https:\/\/helpdeskgeek.com\/wp-content\/pictures\/2021\/06\/8-Ray-Tracing-80x45.jpg 80w\" sizes=\"auto, (max-width: 680px) 100vw, 680px\" \/><\/a><\/figure>\n\t\t\t<\/div>\n\t\t\n\n\n<p>GPU developers have now added dedicated co-processors that do an even more specialized job than the GPU cores.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>The latest generation of Nvidia GPUs have special components that accelerate the mathematics of <a href=\"https:\/\/www.online-tech-tips.com\/what-is-path-tracing-and-ray-tracing-and-why-do-they-improve-graphics\/\" target=\"_blank\" rel=\"noopener\" data-lasso-id=\"15937\">ray tracing<\/a>, which is a method of drawing 3D graphics by simulating how light propagates through a scene.<\/li><li>These GPUs have an additional processor that\u2019s very good at doing so-called \u201ctensor\u201d mathematics.
