The actual limit varies and is determined by the OS and computer configurations. The GPU's driver works in tandem with the operating system to ensure that the memory is allocated for optimal performance between both GPU and CPU. However, Intel Iris chips have a small amount of onboard eDRAM, either 64 or 128MB, that boosts performance. So, if your laptop has 8GB of RAM, the Intel HD Graphics chip will take some of that capacity, often as little as 64 or 128MB, for itself.

Instead they draw from the same system memory as the processor. Integrated graphics don't have a memory bank sequestered somewhere. MORE: Which GPU is Right For You How much Video RAM (VRAM) do Intel integrated GPUs have?

Unlike Intel HD Graphics GPUs, Iris has a small amount of onboard memory to help speed them up. With Iris, you should be able to play some games, However, they still aren't faster than a mainstream discrete graphics chip. Intel's Iris GPUs, which are marketed as either Iris Plus (current gen), Iris Pro (last gen) or just plain Iris (last gen), promise significantly faster performance than regular Intel HD Graphics. They can however, reliably stream video and play certain games including the ever-popular Overwatch. HD Graphics chips aren't built for taxing tasks like AutoCAD or playing titles like Doom, For Honor or Rise of the Tomb Raider.

You'll find some version of the chip in most laptops, even those equipped with discrete graphics. Intel HD Graphics are the more common version of mobile integrated graphics. What's the difference between Intel HD Graphics and Iris Plus?
