Samsung’s GDDR7 achieves up to 25% higher I/O speed per pin compared to the previous generation, delivering leading performance among standardized graphics memory products. This is enabled by the industry’s first application of PAM3 signaling2), which encodes data using three signal levels rather than two in conventional NRZ3), improving bit-level efficiency. This increase in per-pin data rate translates into higher overall bandwidth, enabling faster data processing for AI and graphics workloads.

The main differences between GDDR7 and GDDR6 are improvements in bandwidth, data transfer speed, and signaling technology.
GDDR7 is designed to deliver significantly higher performance, offering faster data rates and greater bandwidth than GDDR6,
even within similar interface widths.
One of the key advancements is the use of PAM3 (Pulse Amplitude Modulation 3-level) signaling,
which allows GDDR7 to transmit more data per clock cycle compared to the NRZ signaling used in GDDR6.
GDDR7 also provides better power efficiency, enabling higher performance while reducing overall power consumption.

GDDR7 is not a type of system memory that is installed on a standard PC motherboard.
Instead, it is a high-bandwidth graphics DRAM that is soldered directly onto GPUs, AI accelerators,
and high-performance computing modules. Because GDDR7 provides extremely high bandwidth and fast data transfer,
it is used in environments that require rapid memory processing, such as advanced graphics rendering, real-time visualization,
machine learning inference, and large-scale parallel computing.
In other words, GDDR7 is a memory technology used on GPUs and accelerator hardware, not on general-purpose motherboards.
