It is said that a large part of the delay of NVIDIA's new card is related to the GDDR6 memory. From the technical point of view, the capacity/pin bandwidth is doubled and the voltage is reduced compared with GDDR5, which is a significant increase in performance.
In Micron's latest release of its technical documentation, its GDDR6's pin bandwidth reaches 20 Gbps.
of course, 20 Gbps is just the laboratory limit and the use of an oscilloscope to observe the internal storage, Micron said that the functional GDDR6 is now up to 16.5 Gbps.
If the bandwidth is 20Gbps, the total bandwidth of a 256bit wide graphics card will reach 640GB/s, which is twice that of the GTX 1080, which exceeds TITAN Xp (547GB/s), and even looks at TITAN V with HBM2 memory (652.8). GB/s).
It is worth mentioning that in January of this year, Samsung announced the mass production of 18GHz (18Gbps) GDDR6 memory, and said it will be used in the next generation of graphics cards, but after that no action.
It is reported that NVIDIA will open a new generation of graphics cards before at least August 20. It is not known whether there will be surprises at the Taipei Computer Show.
