GDDR6 memories are more expensive than GDDR5 memories, but this difference is compensated by other parameters and the gap will narrow in 2019. We have recently learned that GDDR6 memory is 70% more ...

As such, this likely means that throughout 2019, despite GDDR6 being much faster, we can expect more than a few cards to continue utilising GDDR5.

Electronic Components Dealers lists various Micron GDDR5 and GDDR6 chips, pricing for 2,000 units. From these it can be seen that GDDR6 is currently much more expensive than GDDR5 at the moment.

Back to the card we do know about, this new GDDR6 spin of the GTX 1650 has the same TU117-300-A1 GPU as the GDDR5 version, complete with 896 CUDA cores, although it does have slightly lower clocks.

GDDR6 (MIcron insists on the GDDR5X name) is arriving in 2016 at least at Micron and the company promises a much higher bandwidth compared to the GDDR5. So there will be a few choices.

GDDR6 has been created as the next generation graphics solution; GDDR5X is the performance option, while GDDR5 is for cheaper, volume, usage.

The Ti variant will very likely get GDDR6 graphics memory, the non-Ti would get GDDR5 graphics memory as well as a 6GB and 3GB configuration. The 1660 series would not have raytracing cores.

Looking at the important key performance specs of GDDR6, users will benefit from memory bandwidth of 10 to 14Gb/s. That compares very well, as much as doubling up, to the 7.0Gb/s of 4Gb GDDR5.

Samsung's GDDR6 memory is based on the company's 10-nanometer technology and offers double the density of the company's 20-nanometer GDDR5 offerings, meaning 16 gigabits instead of eight gigabits.

Where GDDR5 was an 8n prefetch, and GDDR6 was 16n, GDDR7 will have a 32n prefetch architecture. This is a way to pull larger amounts of data from DRAM while still operating at relatively low clocks.
