NVIDIA has released RTX 3090, RTX 3080 and RTX 3070 three graphics cards, only the flagship RTX 3080 and monster RTX 3090 equipped with Micron’s latest GDDR6X video memory. Today, Micron China has interpreted the key technologies of the new video memory, let’s take a look.
Micron said that GDDR6X, the world’s fastest discrete graphics memory solution, is the first to help system bandwidth achieve 1 TB/sec. For the first time, NVIDIA is equipped with GDDR6X video memory in the new GeForce RTX 3090 and GeForce RTX 3080 graphics processors.
At the technical level, Micron claims that through the application of innovative signal transmission technology-four-level pulse amplitude modulation (PAM4), the data transmission method of memory has been changed, and the breakthrough bandwidth of GDDR6X has been achieved . Since 2006, Micron engineers and researchers have begun to explore the application of multi-level signal technology to memory interfaces. After applying for 45 patents, Micron took the lead in applying PAM4 in memory.
Naijatechnews learned that GDDR6X uses PAM4 multi-level signal technology to achieve faster data transmission and double the input/output (I/O) data rate. Previously, the video memory bandwidth was up to 64 GB/s. The traditional binary standard relied on two-level signal transmission coded as 1s or 0s data, and one bit of data could be transmitted per cycle. Micron’s new PAM4 technology uses four different levels to simultaneously input and output two bits of data to the memory. As a result, Micron’s GDDR6X significantly increased the memory bandwidth of a single particle to 84 GB/s, thereby increasing the system bandwidth to an unimaginable 1 TB/s.
In addition, GDDR6X achieves lower single-task energy consumption (pJ/bit) compared to its predecessors. Through faster speed and lower power consumption, GDDR6X also has the function of adjusting the level of power consumption. Users can adjust lower performance. Save energy.
