Rambus achieves leading GDDR6 performance at 18 Gbps

1 min read

Rambus, the silicon IP and chip provider, has announced that it has achieved an industry-leading 18 Gbps performance with the GDDR6 Memory PHY.

Running at the industry’s fastest data rate of 18 Gbps, the Rambus GDDR6 PHY IP is reported to have delivered a peak performance four-to-five times faster than current DDR4 solutions. The Rambus GDDR6 PHY pairs with the companion GDDR6 memory controller from the recent acquisition of Northwest Logic to provide a complete memory subsystem solution.

Increased data usage in applications such as AI, ML, data centre, networking and automotive systems is driving a need for higher bandwidth memory and the coming introduction of high-bandwidth 5G networks is expected to exacerbate this challenge. Working closely with the company's memory partners, the Rambus GDDR6 solution has been designed to give system designers more options when it comes to selecting the memory system that addresses both their bandwidth and cost requirements.

“Memory bandwidth poses a significant obstacle for designers working on performance-intensive applications such as AI/ML,” explained Hemant Dhulla, vice president and general manager of IP cores at Rambus. “With our GDDR6 18 Gbps memory subsystem, Rambus technology can unleash the power of leading-edge designs with a proven and cost-effective memory architecture.”
