Greymon55 sets the record straight on next-gen RDNA 3 memory bandwidth expectations
That would deliver a final memory bandwidth spec of 960 GB/sec, which isn’t the highest we’ve ever seen on a Radeon—that honor goes to the Radeon VII and its 1 TB/sec—but it is still extremely fast. We are a little surprised AMD didn’t go for broke with Samsung’s screaming 24-Gbps memory , but perhaps the price was too dear.
The massive jump in memory bandwidth on AMD’s next-generation parts may be an attempt to alleviate those effects somewhat. It may also be an attempt to improve performance in certain types of GPU compute workloads. While the RDNA architecture is focused on gaming, the cards are still massive compute accelerators, and it is possible that some vendor or another was disappointed in the relatively limited memory bandwidth of AMD’s current-gen cards.
Memory bandwidth is one of the most important specifications that determines a graphics card’s performance potential. It reflects the maximum data throughput rate between the GPU chip itself and its memory packages.
