The amount of video memory is dependent upon the amount of pre-allocated video memory plus DVMT allocation. DVMT, as its name implies, dynamically allocates system memory for use as video memory to ensure more available resources for 2D/3D graphics performance, e.g. for graphically demanding games.
Analysis by TechSpot found that the RTX 4090's value at 1440p was worse than the RTX 3090 Ti and that the RTX 4090 did not make much sense for 1440p as it was limited by CPU bottlenecks. [90] Power consumption was another point of criticism for the RTX 4090. [90] The RTX 4090 has a TDP of 450W compared to the 350W of its last generation equivalent.
The Direct Rendering Manager was created to allow multiple programs to use video hardware resources cooperatively. [4] The DRM gets exclusive access to the GPU and is responsible for initializing and maintaining the command queue, memory, and any other hardware resource.
A frame buffer may be designed with enough memory to store two frames worth of video data. In a technique known generally as double buffering or more specifically as page flipping, the framebuffer uses half of its memory to display the current frame. While that memory is being displayed, the other half of memory is filled with data for the next ...
Metal allows application developers to create Metal resources such as buffers, textures. Resources can be allocated on the CPU, GPU, or both and provides facilities to update and synchronize allocated resources. Metal can also enforce a resource's state during a command encoder's lifetime. [6] [7]
The GPU having quick access to a high amount of L2 cache benefits complex operations like ray tracing compared to the GPU seeking data from the GDDR video memory which is slower. Relying less on accessing memory for storing important and frequently accessed data means that a narrower memory bus width can be used in tandem with a large L2 cache.
GDI was present in the initial release of Windows. MS-DOS programs had manipulated the graphics hardware using software interrupts (sometimes via the Video BIOS) and by manipulating video memory directly. Code written in this way expects that it is the only user of the video memory, which was not tenable on multi-tasked environment, such as ...
Nvidia NVENC (short for Nvidia Encoder) [1] is a feature in Nvidia graphics cards that performs video encoding, offloading this compute-intensive task from the CPU to a dedicated part of the GPU.
