Introduction to Mixed SLI performance

NVIDIA's hybrid SLI technology is hybrid SLI. Originally on Nvidia's GeForce 8 onboard GPU, the development of the GeForce 8 onboard GPU, codenamed MCP78, was the MGPU product of Nvidia on AMD platforms. As is known to all, Hybrid SLI is comprised of the main technologies of the Hybrid boost and Hybrid power two, wherein Hybrid boost technology refers to the interconnection acceleration between the onboard display core and the standalone graphics card, and Hybrid Power is the energy-saving effect of standalone graphics and onboard display cores running independently of each other under different task loads, and with Nvidia's display driver, we can easily debug hybrid boost and hybrid power under the Windows interface.

With energy resources tight and energy prices increasing today, Hybrid Power's energy-saving features are naturally quite important, and Hybrid boost can be invaluable in maximizing the value of Hybrid acceleration without wasting the onboard display core cost. This shows that hybrid SLI was born to minimize cost and maximize performance.

Performance Introduction

As we all know, Nvidia's SLI improves system performance by using dual graphics interconnect, but the dual graphics card undoubtedly increases the power consumption and calorific value of the system. And Nvidia has announced a new hybrid SLI technology, the so-called hybrid refers to the technology allows the motherboard to display the chip and video card interconnection, so as to reduce power consumption and heat.

According to the Xbitlabs website, hybrid SLI technology will be used in 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, while in the maximum performance mode, the system will allow IGP to assist the GPU to work simultaneously for performance improvement purposes.

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

In the maximized performance mode, IGP can help stand-alone graphics chips, enabling faster processing performance for GPUs with introductory or mainstream graphics performance.

"The so-called hybrid SLI is in a system with integrated graphics chips and separate chips, and when you switch between two GPUs, you don't need to change the display," said Jeff Fisher, general manager of NVIDIA's GPU business unit ... We can render all the work through the motherboard GPU. ”
