Samsung showcases GDDR7 memory at GTC for Nvidia’s RTX 50 series

Samsung teases GDDR7 32Gbps and 28 Gbps GDDR7 modules at GTC 2024

At Nvidia’s GTC 2024 event, HardwareLuxx has spotted a display featuring Samsung GDDR7 memory. On display were Samsung’s 2GB 32Gbps GDDR7 modules. These modules are 33% faster than the fastest GDDR6/GDDR6X chips. These speeds will allow future graphics cards to deliver much higher levels of memory bandwidth.

It has also been reported that GDDR7 memory is due to be used at 28 Gbps speeds initially on next-generation GPUs. This is reportedly due to efficiency reasons. Dropping down to 28 Gbps results in a 17% performance drop, though it remains much faster than the GDDR6/GDDR7 memory used on today’s graphics cards.

At GDC 2024, Nvidia revealed their Blackwell series of AI GPUs. These accelerators are make use of HBM3E memory, not GDDR7. This makes it seem likely that Nvidia are planning to utilise GDDR7 memory on their next-generation RTX 50 series graphics cards. There were even recent rumours that stated that Nvidia’s RTX 50 series flagship would use 28 Gbps GDDR7 memory.

Recently, it has been suggested that Nvidia’s RTX 5090 may use a 512-bit memory bus and 28 Gbps GDDR7 memory. This would give Nvidia’s RTX 5090 a 33% wider memory bus and a 33% boost in GDDR memory bandwidth. These factors combine to deliver a 77% increase in memory bandwidth. That sets up Nvidia’s RTX 5090 to deliver a major generational performance leap over its predecessor.
