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 ...
Select models support Turbo Core technology for faster CPU operation when the thermal specification permits; Select models support Hybrid Graphics technology to assist a discrete Radeon HD 6450, 6570, or 6670 discrete graphics card. This is similar to the Hybrid CrossFireX technology available in the AMD 700 and 800 chipset series
AMD CrossFire (also known as CrossFireX) is a brand name for the multi-GPU technology by Advanced Micro Devices, originally developed by ATI Technologies. [1] The technology allows up to four GPUs to be used in a single computer to improve graphics performance.
This technology implements a sophisticated system to predict the potential usage need for graphics cards and switch between graphics cards based on predicted need. This technology also introduces a new power control plan that allows the discrete graphics cards consume no energy when idling.
The decision to move to a chiplet-based GPU microarchitecture was led by AMD Senior Vice President Sam Naffziger who had also lead the chiplet initiative with Ryzen and Epyc. [6] The development of RDNA 3's chiplet architecture began towards the end of 2017 with Naffziger leading the AMD graphics team in the effort. [7]
Product technology architect Sam Naffziger said that, without Infinity Cache, "We were looking at the daunting prospect of having to put a 512-bit interface and all the power, area and expense associated with that". [15] Using a wider memory bus requires more power which is in conflict with AMD's increased performance-per-watt goals for RDNA 2.
The acquisition of ATI in 2006 was important to AMD's strategic development of its Fusion series of computer processors, which integrated general processing abilities with graphics processing functions within a single chip, which would become a popular option on computers in the following years, especially lower cost models.
In "hybrid mode" most of the computation is done by the 3D engine of the GPU. Using AMD's Accelerated Parallel Programming SDK and OpenCL developers can create hybrid encoders that pair custom motion estimation, inverse discrete cosine transform and motion compensation with the hardware entropy encoding to achieve faster than real-time encoding.
