Rambus grabs the commanding heights: 18GHz GDDR6 memory is demonstrated for the first time.

GDDR6 video memory has gradually become popular. For example, the NVIDIA Turing family has been fully equipped, and AMD Navi has also been introduced. At present, the highest commercial speed is 14GHz, and 16GHz will appear soon. Now Rambus has demonstrated the high frequency GDDR6 of 18GHz for the first time.

Speaking of Rambus, most people have no good impression. This "patent hooligan" once stirred up the whole industry with some accumulation in memory and video memory technology, but it has to be said that Rambus still has two brushes in technology.

With the ultra-high speed of 18GHz, Rambus GDDR6 can get a bandwidth of 72GB/s with only a 32-bit wide chip. With the 256-bit and 384-bit widths on mainstream and high-end graphics cards, the amazing bandwidths of 576GB/s and 864GB/s can be achieved respectively.

In contrast, the total bandwidth of RTX 2080 Ti with 384 bits 14GHz GDDR6 is 672 GB/s.

Rambus's new memory uses the PHY physical layer manufactured by TSMC's 7 nm process, and combines the controller of Northwest Logic and GDDR6 particles from unknown sources.

The official eye diagram also proves that the transmission signal of GDDR6 is still pure at the high frequency of 18GHz.
