Intel Showcases Multi Adapter - bundles of embedded GPU and discrete graphics card

For example, Intel HD 530 with Radeon RX 480

Almost all modern Intel processors have a built-in graphics core. Today, the capabilities of such GPUs are enough for normal work and even to run some old or the most undemanding games.

If a notebook also has a discrete video card, the built-in video card allows you to save energy when performing simple tasks. But is it possible to make the built-in and discrete GPU work together?


Intel has published the presentation materials that were designed for the cancelled GDC 2020 event. One of the presentations is called "Multi-Adapter with Integrated and Discrete GPUs" and is dedicated to creating a multi-adapter, a bundle of integrated and discrete GPUs.

For example, Intel cited a bundle of Intel HD 530 and Radeon RX 480, which is a bit strange, because the company already has samples of its own graphics card DG1. Anyway, the question is still very interesting.

In the framework of the presentation, Intel told about several scenarios of using a multiadapter implemented with the help of Direct3D 12. The first one is the transfer by a discrete adapter of built-in tasks for processing computational shaders, which allows you to release additional power of the discrete one for graphics processing. As an example, Intel showed a simulation of N body consisting of 4 million particles. There are no comparison tests - Intel's task was not to compare this approach to the usual one but to demonstrate the capabilities. It should be noted separately that the bundle of Intel HD 530 and Radeon RX 480 was not the only one used by Intel. It appears in the document on the site, while the video can see another one (Intel HD 630 and Radeon RX 580), and the attached image - the third (Intel HD 630 and GeForce RTX 2080 Ti).

The second scenario - joint rendering of images, for example, with the alternation of frames. But this variant is meaningless for bundles, where a discrete GPU is much more powerful than an integrated one.

The third scenario is asynchronous load execution. For example, tasks of artificial intelligence, calculation of object physics, modeling of particles and shadows and so on.

Given the fact that Intel is preparing to enter the discrete graphics card market this year, and the first obviously will not be very productive, we can assume that with the release of such 3D cards, Intel will present and multiadapter technology.

Separately, we can recall that AMD previously had a technology that allows you to combine a discrete Radeon graphics card with a built-in hybrid GPU, but now it is not used. Besides, Intel's approach implies the possibility of creating multiadapters regardless of the GPU model.
