Samsung has developed the world’s first-ever Graphics Double Data Rate 7 (GDDR7) DRAM which will power the next-generation premium Graphics cards. Designed on Amplitude Modulation-3 (PAM3) technology, the GDDR7 memory boasts up to 1.5 TBps bandwidth capacity, 40% faster than GDDR6.
To compare, GDDR6 memory was built on PAM2 tech and could only deliver up to 1.1 TBps bandwidth. The memory will be used in computers, gaming consoles, automotive vehicles, AI, and other high-performing hardware.
“Our GDDR7 DRAM will help elevate user experiences in areas that require outstanding graphics performance, such as workstations, PCs, and game consoles, and is expected to expand into future applications such as AI, high-performance computing (HPC), and automotive vehicles, said Yongcheol Bae, Executive Vice President of Memory Product Planning Team at Samsung Electronics.
Samsung GDDR7 memory | 32 Gbps speed per pin, more power efficient, less heat generation
The latest graphics memory is expected to bump speed of up to 32 Gbps per pin. It’s a 33% increase from the predecessor GDDR6 memory which could offer 24 Gbps per pin.
However, the original plan is to increase the speed to 36 Gbps per pin. Verge mentions that it’s not unlikely as GDDR6 originally came with 14 Gbps per pin initially which Samsung later raised to 24 Gbps.
Likewise, The improvement also comes in the area of power consumption. Samsung says the GDDR7 memory is more power efficient by 20%. As a result, the performance will also be optimal at lower wattage on gadgets such as laptops and consoles.
The company will also offer an option for the memory which works on low voltage for laptops and computers to be economical with power usage.
Samsung has used an “epoxy molding compound (EMC) with high thermal conductivity” and IC architecture optimizations to minimize heat. So, it will produce less heat and will translate to smoother performance for more duration. The electronics giant claims that it results in a 70% decrease in package thermal resistance compared to GDDR6.
At the same time, memory is also said to be more stable even when it’s working intensely.
Samsung has teased its history-making GPU chips at the time of its worst economic conditions in decades with the hope to restore some of its financial nightmares. The company expects a 96% profit loss in Q2 2023. However, Trendforce says GPU demand won’t be enough to do much for the chip business for now.
Samsung has won the race by being the first to develop GDDR7 memory chips. However, it will take months before going into mass production. Reportedly, the next-generation graphics chips could debut in the first half of 2024. GDDR7 will be used for the next-generation gaming consoles, gaming PCs, AI, and other hardware.
