Samsung GDDR6 16Gb DRAM – 512M x 32

High-Bandwidth Graphics DRAM for GPUs and AI Accelerators

Samsung GDDR6 16Gb (512M x 32) is a high-performance graphics DRAM designed for discrete GPUs, AI accelerators, gaming graphics cards, and high-performance computing platforms. It delivers significantly increased bandwidth and improved power efficiency compared to previous GDDR5 generation memory.

With data rates up to 20 Gbps (speed grade dependent) and architecture capable of scaling toward 24 Gbps, Samsung GDDR6 enables ultra-high bandwidth memory subsystems exceeding 1 TB/s in multi-package configurations.

Key Specifications

• Memory Type: GDDR6
• Density: 16Gb
• Organization: 512M x 32
• Data Rate: 14.0 / 16.0 / 20.0 Gbps (part dependent)
• Voltage: 1.1V
• Package: 180-ball FBGA
• Refresh: 16K / 32 ms
• Status: Production dependent on lot availability

Performance Characteristics

The 32-bit I/O architecture combined with high-speed signaling enables GDDR6 to deliver substantially higher throughput than GDDR5. In multi-chip GPU configurations, total system bandwidth can exceed 1 TB/s depending on bus width and package count.

This makes Samsung GDDR6 16Gb suitable as graphics memory for gaming GPUs, AI inference accelerators, and high performance computing platforms requiring high bandwidth memory chip solutions.

Power Efficiency

Operating at 1.1V, Samsung GDDR6 reduces operating voltage compared to earlier GDDR5 implementations (1.35V / 1.25V). Combined with dynamic voltage switching (DVS), this improves power efficiency while maintaining higher data throughput.
