Nvidia is investing $5 billion in Intel stock, agreeing to purchase shares at $23.28 apiece. Both parties plan to utilize Nvidia’s NVLink interconnect to tightly integrate Nvidia’s GPU (graphics processing unit) processing power with Intel’s x86 architecture, supporting high-performance computing needs.

In August, AMD announced a partnership with IBM to develop future computing systems that integrate quantum technology with high-performance traditional computing. This new approach is called quantum-centric supercomputing.

AMD also designs and develops high-performance computing and graphics technologies, including CPUs, GPUs, and embedded processors. The company's products are used in personal computers, data centers, gaming, and artificial intelligence.

AMD stock has gained over 31% year-to-date and over 7% in the last 12 months.
