Hardcore gamers usually have a dedicated graphics card in their PC, but modern integrated graphics solutions can deliver decent performance in cheaper builds.
You won’t play the latest titles in 4K using an Intel integrated GPU, but if your game library consists of lightweight titles or classic games, integrated graphics are the cheaper solution.
With the launch of its 7th-generation Kaby Lake CPUs, Intel debuted its new generation of integrated graphics processors.
These integrated chips provide a fair amount of graphics processing power and can support resolutions of up to 4K.
We examined Intel’s Kaby Lake integrated graphics processors to find out how effective they are at running modern games.
Hardware
Integrated GPUs share a silicon die and resources with the CPU, and although there are named models with the same specifications, the performance of each GPU varies depending on which CPU it is coupled with.
Intel HD Graphics GPUs do not have dedicated video memory and share RAM with the CPU.
The powerful Intel Iris Graphics processors include onboard eDRAM, though, which is used as dedicated memory for the integrated GPU.
Intel’s 7th-gen processors feature both Intel HD Graphics and Intel Iris Plus graphics chips, with the latter usually reserved for high-end, expensive processors.
The specifications of Intel’s HD and Iris Plus graphics chips are below.

Base Frequency | Max Frequency | eDRAM | Processors |
|---|---|---|---|---|
| Intel HD Graphics 610 | 350MHz | 950MHz | – | Desktop Celeron, Pentium G45, and Core i3-7101 |
| Intel HD Graphics 615 | 300MHz | 1,050MHz | – | Pentium 4410Y, Core i7-7Y75, Core i5-7Y54, Core i5-7Y757, Core m3-7Y30 |
| Intel HD Graphics 620 | 300MHz | 1,050MHz | – | Core i7-7600U, Core i7-7500U, Core i5-7300U, Core i5-7200U, Core i3-7100U |
| Intel HD Graphics 630 | 300MHz | 1,100MHz | – | Desktop Pentium G46, Core i3, i5, and i7, Laptop H-series Core i3, i5, and i7 |
| Intel Iris Plus Graphics 640 | 300MHz | 1,050MHz | 64MB | Core i5-7260U, i5-7360U, i7-7560U, i7-7660U |
| Intel Iris Plus Graphics 650 | 300MHz | 1,100MHz | 64MB | Core i3-7167U, i5-7267U, i5-7287U, i7-7567U |
Gaming Performance
The performance of Intel’s integrated GPUs depends on a number of factors, including the clock speed and L3 cache of the CPU.
However, Intel lists the recommended settings for various titles depending on which processor you own – and this can give users a good idea of their chip’s capabilities.
We have compiled the recommended settings for each integrated graphics chip when playing Blizzard’s Overwatch and Valve’s Dota 2, using information from Intel’s gameplay portal.
Recommended Settings for Overwatch
| GPU | Resolution | Graphics Settings | Lighting Quality | Texture Filtering |
|---|---|---|---|---|
| Intel HD Graphics 610 | N/A | N/A | N/A | N/A |
| Intel HD Graphics 615 | N/A | N/A | N/A | N/A |
| Intel HD Graphics 620 | 1,280 x 720 | Low | Low | Low |
| Intel HD Graphics 630 | 1,280 x 720 | Low | Low | Low |
| Intel Iris Plus Graphics 640 | 1,280 x 720 | Low | Low | Low |
| Intel Iris Plus Graphics 650 | 1,600 x 900 | Medium | Medium | Medium |
Recommended Settings for Dota 2
| GPU | Resolution | Texture Quality | Shadow Quality | Specular Lighting |
|---|---|---|---|---|
| Intel HD Graphics 610 | N/A | N/A | N/A | N/A |
| Intel HD Graphics 615 | 1,920 x 1,080 | Med | Off | Off |
| Intel HD Graphics 620 | 1,920 x 1,080 | Med | Med | Off |
| Intel HD Graphics 630 | 1,920 x 1,080 | Med | Med | Off |
| Intel Iris Plus Graphics 640 | 1,920 x 1,080 | High | Med | Off |
| Intel Iris Plus Graphics 650 | 1,920 x 1,080 | High | High | On |
Intel’s latest integrated GPUs offer superior performance over the previous generation of HD Graphics chips, and are suitable for gamers who want a pleasant experience at a more affordable price.
While the Celeron and Pentium-based chips are not viable for all casual gaming, and the Iris Plus processors require a reduction in resolution for smooth gameplay, the level of performance provided by the higher-end chips is adequate for laptop gaming.
This is particularly the case for laptops with a native resolution of 1,366 x 768.
