Rambus Has DDR5 Memory Working in Its Labs, Gears for 2019 Market Release

The DDR5 RAM modules are getting closer, and finally we begin to have concrete data about their capabilities, as well as an approximate date for them to first get to the servers and then to the home computers. The DDR5 will start arriving in 2019, and will be twice as fast as the DDR4.

The Joint Electronic Devices Engineering Council (JEDEC) is the standardization body responsible for regulating global standards for the microelectronics industry. It has not yet completed an industry standard for DDR5 memory, but we already know some data while the first manufacturer announces having a functional prototype.

Twice as fast as the previous standard

To begin with, the DDR5 is expected to double DDR4 data rates, from 3.2 Gb / s to 6.4 Gb / s, doubling its maximum bandwidth of 25.6 Gb / s of DDR4 current to a maximum of 51.2 GB / s. They are also expected to be around 20% more efficient and to allow the increase of memory channels up to 16, so that manufacturers will be able to get configurations that go from the current 64 GB up to 128 GB.
The JEDEC has also confirmed that the base frequency for DDR5 RAM will be DDR5-4800This may not be too surprising given the fact that the fastest DDR4 memories currently achieve the 4600 MHz, but considering that they started from the DDR4-2400, it is expected that over time the DDR5 can also significantly increase the frequencies according to go passing the time.
The new standard being prepared JEDEC will also lower the 64-bit link to 1.1V, and the burst lengths to 16 bits of 1.2V and 8 bits. In addition, the DDR5 will allow the voltage regulators to be mounted directly on the memory modules themselves instead of having to go on the motherboard as it is today.
The great unknown of the moment surrounding this technology is still the price, which is expected to be quite high . We already told you that the price differences were causing some current computers to continue to mount DDR3 memories instead of DDR4, so it will be necessary to see to what extent the prices of the new memories that will arrive after 2019 are a problem to the time to start implementing the new standard.

Rambus already has its first functional prototype

Dimm Ddr5
Rambus is one of the first manufacturers to have announced a functional prototype DDR5 DIMM memory. They say they expect to start mass production in 2019, and they want to be the first to put it on the market.
"This is the first prototype memory chip with a silicon-proven memory capable of reaching the speeds required for the next DDR5 standard," said Luc Seraphin, Rambus senior vice president and general manager. "Data-intensive applications such as analytics of Big Dates and "machine learning" will be the main drivers of the adoption of the DDR5.
Other manufacturers such as Corsair and G.Skill have yet to announce prototypes. Even so, the logical thing would be that once the first manufacturer starts to market the rest, it will not be too late to follow in his footstepsWe'll keep an eye out to see when these launches will take place.
