It's Official! Micron Begins Mass Production of New High Performance 8Gb GDDR6 Memory Modules
Up until recently, the fastest high performance memory solution available through Micron was the GDDR5 series. We are excited to announce that the highly anticipated GDDR6 has now officially entered the high volume production stage!
The GDDR6 is a special type of DDDR SDRAM capable of meeting large bandwidth requirements. Because of this, it offers users in the artificial intelligence (AI), graphics processing units (GPUs), networking, and automotive markets the latest in advanced performance memory, coupled with lower power consumption. High-speed applications including gaming consoles, graphics cards, network routing and switching, autonomous driving, HPC acceleration, crypto mining cards, and application specific IC will benefit significantly from this powerful high performance graphics memory.
Features & Benefits:
- High bandwidth: Quicker data packet processing and buffering with data rates up to 16Gb/s
- Simplified board design: Simple PCB design with fewer layers improves time to market and accessibility
- Design ease & usability: Similar parallel memory implementation to previous DDR devices
Compared to its previous generations of graphics-based DRAM, the GDDR6 series provides higher densities, double the bandwidth, and backwards compatibility thanks to its dual-channel architecture.
This chart compares the general capabilities of GDDR5 and GDDR6 memory.
