The CPU runs the task assignment application (usually the graphics card driver) to determine which GPU core to use. The CPU passes down the command to the Northbridge. The Northbridge passes down the command to the according GPU core. The GPU core processes the command and returns the rendered data back to the Northbridge.
In the future, libGL-fglrx-glx could use the libDRM of the Radeon open-source driver instead of the proprietary binary blob; most of the investment is in the userspace driver. When applications such as a 3D game engine or a 3D computer graphics software shunt calculations from the CPU to the GPU, they usually use a special-purpose API like ...
A later development to the CrossFire infrastructure includes a dual GPUs with on-board PCI Express bridge that was released in early 2008, the Radeon HD 3870 X2 and later in Radeon HD 4870 X2 graphics cards, featuring only one CrossFire connector for dual card, four GPU scalability. When using two GPUs on board the same system, the HDMI ports ...
Radeon Software 17.7.1 is the final driver for Windows 8.1. Radeon Software 18.9.3 is the final driver for 32-bit Windows 7/10. AMD Software 22.6.1 is the final driver for Windows 7 (and Windows 8.1 unofficially); 22.6.1 is also the final driver for GCN 1, GCN 2 and GCN 3 based GPUs [42]
ROCm [3] is an Advanced Micro Devices (AMD) software stack for graphics processing unit (GPU) programming. ROCm spans several domains: general-purpose computing on graphics processing units (GPGPU), high performance computing (HPC), heterogeneous computing.
The Hybrid CrossFireX is a technology allowing the IGP, or Integrated Graphics Processor, and the discrete GPU, or Graphics Processing Unit, to form a CrossFire setup to enhance the system capability to render 3D scenes, while the Hybrid CrossFire X technology is present on the 790GX and 890G chipsets, with two supplied physical PCI-E x16 slots at x8 bandwidth, [12] can form a Hybrid CrossFire ...
The Nvidia NVENC SIP core needs to be supported by the device driver. The driver provides one or more interfaces, (e.g. OpenMAX IL) to NVENC. The NVENC SIP core can be accessed through the proprietary NVENC API, as well as the DXVA and VDPAU [23] APIs. It is bundled with Nvidia's GeForce driver. NVENC is available for Windows and Linux ...
Nvidia Optimus is a computer GPU switching technology created by Nvidia which, depending on the resource load generated by client software applications, will seamlessly switch between two graphics adapters within a computer system in order to provide either maximum performance or minimum power draw from the system's graphics rendering hardware.
