Life in the fast lane

Faster, more efficient processing

Samsung's GDDR (Graphics Double Data Rate) solutions are optimized to process vast amounts of data, delivering lightning-fast speeds for server applications such as fast-tracking graphics processing. Whether on servers, PCs, or workstations, GDDR can be harnessed for video processing, gaming, and more.

Pushing the boundaries of GDDR

As the first DRAM to feature PAM3 signaling, GDDR7 is a leap forward in computer graphics that can be leveraged in

graphics cards, game consoles, automotive, HPC, and AI/ML. The 30% increase in speed and 20% improvement

in power efficiency1 make it the ideal choice for numerous applications. And thanks to newly introduced package

materials and an optimized circuit design, it offers enhanced reliability with a 70% decrease in thermal resistance.

All of these advantages combine to make GDDR7 an essential solution for the AI era.

1 Speed and power efficiency metrics are in comparison to the GDDR7 predecessor, GDDR6.

Faster speed, enabled by PAM3

Samsung’s GDDR7 offers the fastest available performance of any standardized graphics memory product.
This performance is made possible through the industry’s first application of PAM3 signaling2.
PAM3 transmits 1.5 times more data in the same signal cycle than the conventional NRZ method 3,
giving GDDR7 a 30% performance improvement over its predecessor.

2 Pulse Amplitude Modulation 3 (PAM3) is a signal transmission technology.

3 Non return to zero (NRZ) modulation encodes data using two signal levels, while PAM3 uses three signal levels.

Optimized power usage,

ensuring cost-effective operations

GDDR7 optimizes power, improving power efficiency by 20%. This type of optimization decreases

standby power consumption by 50%, resulting in less power used overall. Less power being consumed

means reduced costs, which contributes to lowering customers’ total cost of ownership (TCO).

Supreme stability

Benefit from higher reliability. GDDR7 achieves a 70% decrease in thermal resistance4 by using new package materials and an optimized circuit design. This allows it to avoid excessive heat generation, which prevents product degradation, performance loss and other potential hardware issues.

• Game changer of graphics power

Now the real game begins

Industry's fastest speed. Greater power efficiency. Incredible versatility.

The newly upgraded Samsung GDDR6 changes the rules of graphic DRAM performance,
setting a new standard for the graphics experience.

24Gbps. Memory’s high-speed makeover

Samsung GDDR6 is memory’s biggest makeover, with speeds reaching up to 24Gbps.

With the highest speeds of any standardized product, it delivers maximum bandwidth
and blazing-fast data speeds to enable up to 1.1TB/s* of computing performance
- a full 30% faster than the previous generations.
A new stage of high-performance computing (HPC) and graphics is here.

*1TB/s Bandwidth rates are based on a 12pkg/system application

Only 1.1V. All you need and more

Voltage is down and speed is up - higher than ever.

Our upgraded GDDR6 supports 1.1V of power, exceeding the industry standard of 1.35/1.25V.

That's all made possible by innovative circuit design and low-power dynamic voltage switching (DVS),
allowing GDDR6 to push power efficiency to the max, allowing high-bandwidth, high-computing tasks
with only a fraction of the standard power requirements.

World’s first 16Gb. Do the most

More space, with more ways to use it.

The world’s first 16Gb graphics DRAM massively widens its scope and possibilities, bringing adaptability and broader applications to the forefront.
Welcome to stunningly realistic and latency-free gaming for PCs and laptops,
unlimited creativity for professional workstations, and transporting viewing experiences for vehicle entertainment systems.

And it still consumes up to 60% less than previous 8Gb solutions with the same density configuration.

Stage clear. Onto a whole new stage

And it's not all about gaming.

Samsung's GDDR6 is built to stretch the role of graphic DRAM in computing to a wider ecosystem of applications
– from VGA and computers to high-performance computing, and gaming to AI.

Combining industry-leading performance, power, and bandwidth, Samsung's GDDR6 takes graphics to the next level,
paving a new way for future technologies in AI and future computing, while securing reliability for the widest range of applications.

Get ready for a whole new stage.
