What does shared gpu memory mean?

Shared gpu memory means the priority memory capacity specially divided by the WINDOWS10 system for the graphics card; when the graphics card memory is not enough, the system will give priority to this part of the "shared GPU memory"; in the WIN10 system, it will be divided into half The physical memory capacity of the capacity is "shared GPU memory".

What does shared gpu memory mean?

"Shared GPU memory" is the priority memory capacity specially allocated by the WINDOWS10 system for graphics cards. When the graphics card memory is insufficient, the system will give priority to this part of the "shared GPU memory". In the WIN10 system, half of the physical memory capacity will be divided into "shared GPU memory". Just like this machine has 16G of memory, half of 8G is divided into "shared GPU memory".

Note:

When the program is running, the WIN10 system will give priority to the graphics card memory, but when the program requires more graphics memory than the memory capacity, In order to avoid program crashes, the WIN10 system will borrow memory from the "shared GPU memory" to the graphics card as video memory. However, the borrowed capacity will not exceed the total capacity of "shared GPU memory".

Because the bandwidth and latency of memory are relatively small compared to video memory, it will inevitably lead to a reduction in program running efficiency. If it is placed in a game, it will cause frame drops and lags. However, although "shared GPU memory" occupies half of the physical memory capacity, it does not mean that other programs cannot use this memory capacity. It is a shared capacity, but it is given priority to the graphics card.

Gpu introduction:

Graphics processor (English: graphics processing unit, abbreviation: GPU), also known as display core, visual processor, display chip, is a special type of computer, Microprocessors that perform image and graphics-related operations on workstations, game consoles, and some mobile devices (such as tablets, smartphones, etc.).

The GPU reduces the graphics card's dependence on the CPU and performs some of the original CPU's work, especially in 3D graphics processing. The core technologies used by the GPU include hardware T&L (geometry conversion and lighting processing), cubic environment Material mapping and vertex blending, texture compression and bump mapping, dual texture four-pixel 256-bit rendering engine, etc., and hardware T&L technology can be said to be the hallmark of GPU. The main manufacturers of GPUs are NVIDIA and ATI.
