Multi-gpu rendering system

Abstract

A multi-GPU rendering system according to a preferred embodiment of the present invention includes a CPU, a chipset, the first GPU (graphics processing unit), the first graphics memory for the first GPU, a second GPU, and the second graphics memory for the second GPU. The chipset is electrically connected to the CPU, the first GPU and the second GPU. Graphics content is divided into two parts for the two GPUs to process separately. The two parts of the graphics content may be the same or different in sizes. Two processed graphics results are combined in one of these two graphics memories to form complete image stream and then it is outputted to a display by the GPU.

Description

technical field [0001] The present invention relates to a graphics processing system with multiple graphics processing units for asymmetric load balancing and increased operating efficiency and performance improvement, and more particularly to a graphics processing system with multiple graphics processing units using a system memory to facilitate data access Unit's graphics processing system. Background technique [0002] As the demand for higher computer graphics quality, especially 3D and real-time computer graphics quality, increases in the market, many methods for improving the speed and quality of computer graphics are known. In the prior art, the field of using multiple graphics processing units to speed up graphics processing is one of the important branches. However, it can be seen that several technical difficulties need to be overcome to realize a multi-GPU system. First, there is a need to distribute rendering commands among arbitrary GPUs in a multi-GPU system....

AI Technical Summary

Problems solved by technology

Further, due to the use of additional cables or chips or circuits to electrically connect each graphics processing unit for image merging or communication, most of the graphics rendering systems with multiple graphics processing units in the prior art are complex in structure and expensive. expensive

In addition, only a few chipsets can be provided to match the multi-GPU system, which not only reduces the universality of the motherboard but also increases the manufacturing cost

[0004] In addition, for commercial and technical reasons, in the prior art, the GPUs that make up a multi-GPU system are usually from the same manufacturer or limited to the same GPU core, which limits the flexibility of choice for consumers
