Samsung GDDR7 Memory Unveiled With Up To 32 Gbps Speed

Expert Verified By

First Look At GTC 2024!

Story Highlights
  • Samsung has announced its GDDR7 memory chips at GTC 2024.
  • The new chips boast speeds of up to 32 Gbps and efficiency gains.
  • Nvidia’s next-generation gaming graphics cards are likely to be paired with these memory chips.

During the GTC event, Samsung Electronics announced its long-rumored 32 Gbps GDDR7 memory chip. This chip represents a significant advancement in the speed and energy efficiency of future graphics cards.

Samsung has been showcasing the GDDR7 memory with speeds of 28 and 32 Gbps. HardwareLuxx, who observed the GDDR7 memory at GTC 2024, has released a new image of the memory.

Samsung GDDR7 Specifications

Nvidia also just unveiled its next-generation Blackwell GPUs at GTC 2024, but they were using blazing-fast HBM3E memory. However, consumer graphics cards based on the new Blackwell architecture are rumored to feature Samsung’s GDDR7 memory.

In comparison to the industry standard 1.2V, Samsung claims that the new GDDR7 memory has 20% greater power efficiency at just 1.1V. This is significantly less than the 1.35V that the power-hungry GDDR6X memory modules consume.

The initial Nvidia graphics cards that feature the new GDDR7 memory may operate a little bit slower at 28 Gbps despite their maximum speed of 32 Gbps. This implies that Nvidia may still have room to improve the speed or efficiency of its GPUs in the future.

The chip’s ability to withstand heat has also been significantly enhanced. The improved cooling capabilities of the new chip design allow for a 70% reduction in heat generation over the previous generation of GDDR6 chips.

The good news is that since the new chip won’t heat up as quickly, graphics cards that use it should last a lot longer compared to GDDR6X memory. Additionally, it does not require extreme cooling solutions to run at stable temperatures.

While Nvidia has yet to provide details about the GeForce RTX 50 series based on Blackwell architecture, there is a high possibility Nvidia might opt for GDDR7, which should provide performance improvements due to its higher bandwidth.

Blackwell gaming graphics cards are expected to arrive in 2025, possibly utilizing the same 4nm manufacturing process as their predecessors.
