What does it mean to mix SLI?

NVIDIA's hybrid SLI technology is hybrid SLI. First appeared on Nvidia's GeForce 8 onboard GPU, the GeForce 8 onboard GPU, code-named MCP78, was the MGPU product of Nvidia on the AMD platform. As we all know, Hybrid SLI is made up of the two main technologies of Hybrid boost and Hybrid power, where Hybrid boost technology refers to the interconnection acceleration between the onboard display core and the independent video card, while Hybrid Power refers to the independent graphics and the onboard display core under the different task load of their respective operation and achieve the energy-saving effect, through the NVIDIA display driver, we can in the Windows interface to hybrid boost and hybrid power for easy debugging.

In the energy resource is tight, the energy price is increasing day in, the Hybrid power Energy saving function naturally is very important, but Hybrid boost can realize the Hybrid acceleration value maximization without wasting the onboard display core cost to be more valuable. This shows that hybrid SLI was born to minimize cost and maximize performance.

Performance Introduction

It is well known that NVIDIA SLI uses dual graphics cards to enhance the performance of the system, but at the same time dual graphics card undoubtedly increases the system's power consumption and calorific value. Nvidia recently announced a new hybrid SLI technology, the so-called hybrid means that the technology allows the board to display chips and graphics interconnect, so as to reduce power consumption and calorific value.

According to the Xbitlabs website, mixed SLI technology will adopt two modes, namely, power saving mode and maximum performance mode. In power-saving mode, the graphics card will turn off the independent graphics core, using only the integrated graphics engine, and in the maximum performance mode, the system will allow IGP to assist the GPU to work together to achieve performance-enhancing purposes.

Nvidia explains that while Nvidia's multi-GPU SLI technology can significantly improve system performance, it also brings with it high power consumption, high heat and high noise and other by-products. And the hybrid SLI technology in the power-saving mode without the need for strong 3D performance, you can block such as GeForce 8,800-level dual graphics cards. Especially in the notebook platform, this mode can give the system a powerful graphics kernel, but also can guarantee the system standby time.

In maximizing performance mode, IGP can help independent graphics chips, enabling a GPU with an entry-level or mainstream graphics performance to perform faster.

"Mixed SLI refers to a system with integrated graphics chips and stand-alone chips, and when you switch between two GPU, you don't need to change the display," said Jeff Fisher, general manager of NVIDIA GPU business. We can use the motherboard GPU to render all the work. ”
