Micron Technology, Inc.,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 newNVIDIA®GeForce RTX™ 3090 and GeForce RTX 3080 graphics processing units(GPUs), which aretailored to support the fast speeds that immersive, high-performance gaming applications demand.
“Our multilevel signaling innovation in GDDR6X hasshattered conventional bandwidthlimits, 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 hasunparalleleddata rates thatcan keep pace with gaming innovation and data-hungryapplications— setting a new standard for graphics memory.”
Micron’s GDDR6X serves as a powerful enablerofNVIDIAGeForce RTX 3090 and GeForce RTX 3080graphics cards’ performance. Building on its most recent collaboration with NVIDIA for theGeForce 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.
“With the unprecedented speed of GDDR6X, Micron has delivered tomorrow’s memory technology today, and it’s at the heart of NVIDIA GeForce RTX 3090 and 3080 GPUs — helping us deliver rich, realistic, cinematic user experiences,” said Jeff Fisher, senior vice president of the GPU Business Unit at NVIDIA. “Building on a history of collaboration that started with GDDR5, we’re thrilled to have reinvented the memory/GPU interface with Micron, setting a new bar for high-performance, high-resolution gaming.”
As PC gaming evolves in sophistication, gamers today demand the highest performance for their advanced graphics cards — a requisite for smooth animation, sharp visuals, 8K resolution and real-time ray tracing, a rendering technique that results in realistic light reflections and cinematic effects. 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.
The new NVIDIA GeForce RTX 30 Series GPUs— the second generation of the NVIDIA RTX PC gaming platform — feature new ray tracing cores, Tensor Cores and streaming multiprocessors. The results are stunning visuals, amazingly fast frame rates and artificial intelligence acceleration for games and creative applications. Powered by the NVIDIA Ampere architecture, which delivers increases of up to 1.9 times performance-per-watt over the previous generation, the RTX 30 Series effortlessly powers graphics experiences at all resolutions, even up to 8K. The series represents the greatest GPU generational leap in NVIDIA’s history.
Beyond the Binary: First to Implement PAM4 in Memory, Micron Sets New Benchmark
Micron achieved GDDR6X’s breakthrough bandwidth byapplyinginnovative 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.
By using PAM4 multilevel signaling techniques, GDDR6X transfers data much faster, doubling the input/output(I/O) data rate.Until now, graphics memory was capped at 64 gigabytes per second (GB/s), transmitting one bit per cycle through the traditional binary standard, which relies on two signal levels to transmit data encoded as 1sor 0s. Instead, Micron’s novel PAM4 technique employs four distinct levels to transmit two bits of data to and from the memory at a time. As a result, Micron’s GDDR6X dramatically increases memory bandwidth to 84 GB/s for each component, translating to system bandwidth of up to 1 TB/s— rates once thought impossible.
Micron’s GDDR6X is also the onlymemory device using PAM4 that can be designedand built in massproduction 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. Notably, GDDR6X doubles the data rate in a channel without doubling the required operating frequency, creating a smooth, real-time experience for gamers.
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 lightningfast and low-power memory. GDDR6X also features the ability to scale power down or up, allowing users to dial back performance to save energy.
