El AMD Financial Analyst Day 2020 has given a brutal amount of data that strengthens the position of the company. We know Infinity Fabric for being a communication technology between DIE and DIE I / O of the new processors. Infinity Fabric increases in importance, becoming one more element in architectural design. Go to have a higher level of integration in future products.

Its first implementation beyond the DIEs of the Ryzen, Threadripper and EPYC processors will be in CDNA. The advanced solution for AI and Machine Learning, among others, which is based on RDNA will integrate this technology to communicate the GPU with the HMB2E memories. A technology that was integrated in the beta phase in the first Ryzen that has evolved to be a more efficient technology.

Infinity Fabric gains weight for AMD

Zen was the first version of processors to integrate the Infinity Fabric, described as a superset of HyperTransport. It is used as a connectivity system between chiplets within the company's current processors. Become a solution that allows multiple sockets to communicate on servers. They also want to offer it as a connectivity solution between GPUs.

The second iteration of Infinity Fabric allows two EPYC processors and four GPUs to communicate in a ring. Note that the connection between the CPU and the GPU is based on the PCIe interface. The next generation, dubbed Infinity Architecture, will allow a total interconnection of up to 8 GPUs or CPU-to-GPU connectivity. It should offer improved communication, memory unification, and other enhancements.

The first system to make use of Infinity Arquittecture will be El Capitan, the system announced a few days ago. This system will feature a Zen4-based EPYC Genoa processor and up to 4 GPUs per processor. Interestingly, this system is based on the design of the baseball playing field.
