Comparing GDDR7 vs HBM3 Specs – What we know so far!

As the demand for high-performance computing continues to grow, so does the need for more advanced memory technologies. Two of the most anticipated advancements in graphics memory are GDDR7 and HBM3, both of which are currently in development by Samsung and SK Hynix, respectively. In this post, we’ll take a closer look at these two technologies and compare their features based on the information available so far.

GDDR7: The Next Step in Graphics Memory

Developed by Samsung, GDDR7 is set to take graphics memory to new heights. The goal for GDDR7 is to achieve data rates as high as 36 Gbps per pin, a significant increase from its predecessors. One of the key features of GDDR7 is its real-time error protection, which is designed to maintain high speeds while ensuring module stability.

In addition to these features, Samsung showcases 27Gbps GDDR6 memory featuring Merged-MUX TX, Optimized WCK Operation, and Alternative Data-Bus. This memory would be even faster than Samsung’s recently announced 24Gbps memory, which is now being sampled.

HBM3: Pushing the Boundaries of Bandwidth

On the other side of the spectrum, we have HBM3, which SK Hynix is developing. HBM3 is set to offer extreme levels of memory bandwidth, with SK Hynix currently forming a 12-Hi (layer) HBM3 DRAM with a speed of 820 GB/s to 896 GB/s. This would be achieved through TSV (through silicon via) auto-calibration and machine-learning optimizations.
