Today, Micron extends its performance leadership by delivering new graphics memory with 16GB capacity and industry-leading 21GB/s in the GeForce RTX 3090 Ti. With a performance roadmap of up to 24 Gb/s, GDDR6X is ready for the data-intensive applications of the future. Additionally, Micron’s innovative use of PAM4 signaling techniques in GDDR6X makes it more power efficient than any of the publicly available GDDR6 products.

Here are the bandwidth figures you can expect with a 24 Gbps DRAM solution:

  • 512 bit solution – 1.5 TB/s
  • 384 bit solution – 1.1 TB/s
  • 320 bit solution – 960 GB/s
  • 256 bit solution – 768 GB/s
  • 192 bit solution – 576 GB/s
  • 128 bit solution – 384 GB/s
  • 92 bit solution – 276 GB/s
  • 64 bit solution – 192 GB/s

“Micron’s industry-leading GDDR6X memory capabilities help bring new levels of realism and performance to the most demanding applications,” said Mark Montierth, vice president and general manager of high-performance memory and product development. networked at Micron. “Micron is once again at the forefront of memory innovation, powering today’s highest bandwidth solutions and built with advanced process and interface technology to enable continued leadership when it comes to graphics performance.”

As games and graphics rendering techniques become increasingly sophisticated, graphics processing units require massive amounts of data to move at incredible speeds, which can challenge system graphics memory. VR gaming, 4K and 8K monitors with 240Hz refresh rates, and intense 3D CAD applications push the limits of graphics systems. GDDR6X’s unparalleled memory bandwidth enables these high-resolution experiences with ultra-fast frame rates and near-instantaneous rendering, providing users with realistic effects. GDDR6X capabilities, built into the GeForce RTX 3090 Ti graphics card, enhance real-time ray tracing and neural graphics processing to deliver the immersive cinematic effects that virtual worlds demand. The GeForce RTX 3090 Ti features 24GB of GDDR6X enabling 40 teraflops of GPU performance.

The revolutionary bandwidth of GDDR6X is possible thanks to Micron’s groundbreaking work with PAM4 signal transmission technology, which has revolutionized the way memory moves data. Micron’s PAM4 signaling technique means that GDDR6X increases memory bandwidth and powers system bandwidth up to 1 TB/s, making it the optimal choice for graphics applications that require exceptionally fast memory and low consumption. No other memory vendor offers this capability.

The addition of 16GB GDDR6X memory marks an important step in the growth of Micron’s ultra-bandwidth solution portfolio, which includes GDDR6 and HBM2E. Together, these solutions constitute the industry’s most comprehensive portfolio of high-performance, high-throughput products designed to power data-intensive applications.
