When we ran our usual suite of performance testing benchmarks, machines that should have yielded comparable graphics performance did not. I noticed this when we recently reviewed some of the latest rugged laptops and tablets based on Intel 11th gen Tiger Lake chips.
Why this whole preamble? Because things are getting a bit confusing. The “Xe” indicates a new and more powerful instruction set architecture. Intel considers that a good step up from the Intel UHD Graphics in earlier processor generations. Higher-end integrated graphics often carried the “Iris” name, and the Intel “Tiger Lake” 11th generation processors we’re now seeing in high end rugged laptops and tablets come with integrated Intel Iris Xe graphics. These have their own memory and power source, and provide significantly higher performance than the graphics integrated into CPUs.īeing sensitive to the demand for more graphics power, Intel has been enhancing the graphics integrated into their processors for years, often using them to distinguish processors from one another.
Rugged laptops and high-end tablets often have “discrete” graphics options. Others are simpler and more affordable, and some are just modules. Some are big, heavy add-on cards with their own fans and power supplies, costing thousands of dollars. That’s where modern-day graphics cards come. And computer gamers will tell you that there’s never enough graphics performance for their ever more complex games. CAD (Computer-Aided Design), high-end imaging, 3D graphics are examples that need more graphics punch. Intel’s integrated graphics are plenty good enough for most work, but there are tasks and industries that need more graphics firepower. Around 2010, wanting to play a bigger part in graphics, Intel began integrating graphics directly into the CPU, and that’s the way it’s been ever since.
Graphics were part of the chipsets that worked in tandem with CPUs, and if that wasn’t good enough, there were separate graphics cards.
Until about a decade ago, most computer processors did not include graphics. Augby conradb212 When things hidden in fine print can mean the difference between your computer being fast or sluggish
