After the publication of the LPDDR5X memory standard earlier this summer, Samsung has now been the first vendor to announce new modules based on the new technology.

The LPDDR5X standard will start out at speeds of 8533Mbps, a 33% increase over current generation LPDDR5 based products which are running at 6400Mbps.

LPDDR Generations
  LPDDR3 LPDDR4 LPDDR4X LPDDR5 LPDDR5X
Max Density 32 Gbit 64 Gbit 32 Gbit
Max Data Rate 2133Mbps 4266Mbps 6400Mbps 8533Mbps
Channels 1 2 1
Width x32 x32 (2x x16) x16
Banks
(Per Channel)
8 8 8-16 16
Bank Grouping No No Yes
Prefetch 8n 16n 16n
Voltage 1.2v 1.1v Variable
(Max 1.1v)
Vddq 1.2v 1.1v 0.6v 0.6v

Samsung’s implementation notes 16-gigabit dies (2GB) on a 14nm process node, with the company explaining that the new modules will use 20% less power than LPDDR5. It’s also possible to allow for 64GB memory modules of a single package, which would correspond to 32 dies.

“Later this year, Samsung will begin collaborating with global chipset manufacturers to establish a more viable framework for the expanding world of digital reality, with its LPDDR5X serving as a key part of that foundation.”

We generally expect LPDDR5X SoCs and products to start being released for the 2023 generation of devices.

    He is talking GPU cores.

    I do not think the CPU will grow in imediate future but A15 - The M2 gen “slice” has 5 GPU cores up from 4 in A14.

    20 and 40 cores will go only to iMac and Mac Pro. Laptops will stay with 10 cores Reply

    Different companies define what a 'GPU core' is, differently. A 32-core Apple GPU is roughly equivalent to a '6144-core' RTX 3080M. Reply

    Stream Processors (sp) have been the baseline for gpu cores for a long time. SOC vendors wanted to increase marketable core counts without increasing cores, so they added gpu ‘cores’. However, these cores were clusters of cores because otherwise they would be marketing hundreds of cores and the measure would become meaningless. Currently Apple gpu cores have 128 sps. This is analogous to the nvidia sm which contains 128 cuda cores (nvidia calls their sps cuda cores). So a 32 core Apple gpu has 4096 sps, not 6144. Not all sps are created equal due to architectural and memory bandwidth differences, and clock speeds are proportional to performance (not 1:1 due to other bottlenecks). Reply

    If your smartphone doesn't have 64 GB of LPDDR5X, you might as well chuck it in the trash. Reply

    Has it suddenly stopped making phone calls? Reply

    Wait, you make phone calls with a phone? How 2020! Reply
