(Double Data Rate Graphics) GDDR is double data rate (DDR) memory designed specifically for graphics cards’ quick rendering (GPUs). The main graphics RAM in use today is GDDR, which was first introduced in 2000. Technically referred to as “GDDR SDRAM,” GDDR replaces VRAM and WRAM.
Although GDDR versions are based on DDR memory, they do not mathematically match DDR, each generation of GDDR is quicker and comes with improvements. For instance, GDDR3 and GDDR5 were built using DDR2 and DDR3 chips, respectively.
Similar to GDDR4, which it replaces, GDDR5 is based on DDR3 SDRAM memory, which has twice as many data lines as DDR2 SDRAM. Similar to GDDR4 and DDR3 SDRAM, GDDR5 also has prefetch buffers that are 8 bits wide.
The Global GDDR5 Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Samsung announced the addition of a 512GB DDR5 module built using the high-k metal gate (HKMG) manufacturing technology to its DRAM memory lineup. The new memory module is made to meet the demands of workloads with high bandwidth and high processing demands found in supercomputing, artificial intelligence (AI), and machine learning (ML).
The South Korean manufacturer asserted that its DDR5 DRAM can produce up to 7,200 Mbps of data transmission rate, which is more than twice as fast as current DDR4 modules.
Samsung claims that choosing the HKMG technology for the insulating layer of the new memory module over the more conventional silicon oxynitride will result in a 13 percent reduction in power consumption over DDR4 modules.
Through-silicon via (TSV) technology is used to connect eight layers of 16Gb DRAM chips together to create Samsung’s DDR5 DRAM, which has a capacity of 512GB. To meet changing memory demands over time, the business is experimenting various DDR5 module versions.
