Micron Technology Reveals GDDR6X for Photorealistic 3D Experience
Micron Technology has announced the world’s fastest discrete graphics memory solution,GDDR6X, the first to power system bandwidth up to one terabyte per second (TB/s).
Working with visual computing technology leader NVIDIA, Micron debuted GDDR6X in the new NVIDIA®GeForce RTX™ 3090 and GeForce RTX 3080 graphics processing units(GPUs), which are tailored to support the fast speeds that immersive, high-performance gaming applications demand.
“Our multilevel signaling innovation in GDDR6X has shattered conventional bandwidth limits, clocking record-breaking speeds,”said Tom Eby, senior vice president and general manager of the Compute & Networking Business Unit at Micron. “Unlike traditional memory, GDDR6X has unparalleled data rates that can keep pace with gaming innovation and data-hungry applications— setting a new standard for graphics memory.”
Micron’s GDDR6X serves as a powerful enabler of NVIDIA GeForce RTX 3090 and GeForce RTX 3080 graphics cards’ performance. Building on its most recent collaboration with NVIDIA for the GeForce RTX graphics card (enabled by GDDR6), Micron transforms the memory/GPU interface with GDDR6X, accelerating performance on complex graphics workloads across next-generation gaming applications.
GDDR6X’s groundbreaking speed offers discerning gamers high-resolution experiences with maximum frame rates and instant rendering, allowing users to experience highly realistic and reactive effects without jarring lags. Combined with NVIDIA’s GeForce RTX 3090 and GeForceRTX 3080 GPUs, GDDR6X’s ultra-bandwidth capabilities improve real-time ray tracing and neural graphics processing to create photorealistic and immersive virtual worlds in PC games.
Beyond the Binary: First to Implement PAM4 in Memory, Micron Sets New Benchmark
Micron achieved GDDR6X’s breakthrough bandwidth by applying innovative signal transmission technology,four-level pulse amplitude modulation (PAM4),to revolutionize how memory moves data. Since 2006, Micron’s engineers and researchers have explored applying multilevel signaling to the memory interface. Over 45 patents later, Micron is the first in the industry to implement PAM4 in memory, creating a new benchmark for future generations of graphics memory.
Micron’s GDDR6X is also the only memory device using PAM4 that can be designed and built in mass production volumes, bringing cutting-edge I/O research to market. With its board design and packaging carefully fine-tuned for simplicity by Micron’s graphics memory experts, GDDR6X offers customers easy implementation and less manufacturing complexity than other high-bandwidth solutions on the market.
In addition, GDDR6X delivers lower power per transaction (pJ/bit) than previous generations, making it ideal for energy-sapping workloads like gaming and other high-bandwidth graphics applications, which demand both lightning fast and low-power memory. GDDR6X also features the ability to scale power down or up, allowing users to dial back performance to save energy.
