Samsung GDDR6 8Gb DRAM – 512M x 32

High-Speed Graphics DRAM for GPUs and Compute Platforms

Samsung GDDR6 8Gb (512M x 32) is a high-performance discrete graphics DRAM designed for gaming GPUs, AI accelerators, and high-performance computing systems. It delivers increased bandwidth and improved power efficiency compared to previous GDDR5 implementations.

With data rates up to 16.0 Gbps (speed grade dependent), Samsung GDDR6 enables high-throughput graphics rendering and compute-intensive workloads while maintaining lower operating voltage at 1.1V.

Key Specifications

• Memory Type: GDDR6
• Density: 8Gb
• Organization: 512M x 32
• Data Rate: 12.0 / 14.0 / 16.0 Gbps
• Voltage: 1.1V
• Package: 180-ball FBGA
• Refresh: 16K / 32 ms
• Status: Production dependent on availability

Performance Characteristics

The 32-bit interface architecture combined with high-speed signaling significantly increases memory bandwidth over GDDR5. In multi-chip GPU configurations, total bandwidth can scale beyond 700 GB/s depending on memory bus width and system design.

This makes Samsung GDDR6 8Gb suitable as graphics memory for gaming GPUs, embedded GPU systems, and AI inference platforms requiring high bandwidth memory chip solutions.

Power Efficiency

Operating at 1.1V, Samsung GDDR6 reduces core voltage compared to earlier GDDR5 generations. Dynamic voltage switching (DVS) improves overall power efficiency, lowering thermal output in dense GPU board layouts.
