GDDR6

While GDDR6 is currently available at speeds up to 14Gbps, and 16Gbps speeds are right around the corner, if the standard is going to have as long a lifespan as GDDR5, then it can't stop there. To that end, Rambus this week demonstrated operation of its GDDR6 memory subsystem at a data transfer rate of 18 GigaTransfers/second, a new record for the company. Rambus’s controller and PHY can deliver a peak bandwidth of 72 GB/s from a single 32-bit GDDR6 DRAM chip, or a whopping 576 GB/s from a 256-bit memory subsystem, which is what we're commonly seeing on graphics cards today. The Rambus demonstration involved the company’s silicon-proven GDDR6 PHY implemented using one of TSMC’s 7 nm process nodes, accompanied by Northwest Logic’s GDDR6...
