Next-gen graphics memory GDDR7 extremely increases bandwidth
Samsung says it has already started manufacturing the next generation of memory chips for graphics cards. The GDDR7 memory is supposed to almost double the previous memory bandwidths of graphics cards.
Samsung gave details about the next generation of graphics memory chips at a tech conference in San Francisco. GDDR7 is supposed to enable an increase in data throughput from the current 18 Gbps with GDDR6 memory to a whole 36 Gbps in the future.
In practice, 1728 gigabits per second should be possible with GDDR7 via a 384-bit bus. For comparison: Even Nvidia's current GeForce RTX 4090 currently only achieves a maximum of 1000 gigabits per second.
For the GDDR7 memory, Samsung relies on a signaling technology called PAM-3, which enables three bits per clock cycle, increasing the bandwidth to 50 percent depending on the operating frequency. PAM-3 is also supposed to be 25 percent more energy-efficient, which can prove to be advantageous in view of the power-hungry hardware of current graphics cards.
According to its own statements, Samsung, as one of the leading memory chip manufacturers, does not intend to reduce its investments despite the current difficult market situation for silicon chips. It plans to expand its production facilities in order to be able to provide around 50 percent more capacity for the production of all types of chips over the next five years.
After all, manufacturers of graphics cards benefit from the fact that the chips would not require new PCB boards, especially since the prices in the graphics card market are highly competitive anyway. However, it is still unclear when the first graphics cards with GDDR7 will reach the market.
Even more bandwidth in graphics cards will also have a positive effect on computing performance when using increasingly more complex algorithms in video surveillance impact. The field of application of artificial intelligence in video surveillance opens up a very broad spectrum, from early fire detection and car license plate recognition to people counting and prediction of possible thefts.
