To the future and beyond: Samsung announces the next generation of RAM chips for mobile
Aside from building shiny, shiny flagship smartphones, Samsung is known to push the boundaries by actively developing hardware, too — the high-powered guts that make our phones tick. The company was first to mass-produce 4 GB LPDDR4 RAM chips in the past and it has even helped industry leader Qualcomm in building its Snapdragon chips before, when the silicone slinger was stuck in an overheating rut. Today, Samsung has announced that it has successfully developed the first 10 nm class LPDDR5 DRAM chip.

What does this mean? Well, the LPDDR5 standard is 1.5 times faster than the current top-tier LPDDR4X chips with a data rate of 6,400 megabits per second. In terms of raw data transfer, this means that LPDDR5 can send 51.2 GB of data within a single second.

OK, what does this mean in terms of applicability? According to Samsung, this fast new chip will allow for more powerful machine learning applications on mobile devices, making AI functions faster and better, as well as improve UHD resolution capture, editing, and playback. Additionally, it's an important component for unlocking the 5G speeds of the future.

What about power requirements? Well, LPDDR5 might actually be more battery-friendly than LPDDR4, due to the fact that it has been engineered to lower its voltage when less output is required by the processor. Additionally, it has a new “deep sleep mode”, which is twice as effective as LPDDR4's current “idle mode”, and has been set up to avoid constantly overwriting cells with a “0” value in them. As a result, Samsung says, LPDDR5 memory is up to 30% more power-efficient than its predecessor.

It's also worth noting that the new LPDDR5 DRAM chips will be available in two configurations. A 6,400 megabit variant that operates at 1.1 V and a slower, 5,500 megabit option, which draws slightly less power at 1.05 V.

When are we going to see this new, ultra-fast RAM chips in our smartphones? Well, if Samsung doesn't partner up with someone who's about to launch a new top-tier handset by the end of 2018, we fully expect the upcoming Galaxy S10 to have the new tech on board.

*NAND and DRAM memory Intel and TSMC still lead in semiconductor logic production

Samsung semi makes more revenue and profit than both so .....

True Samsung make more money overal But I'm taking about performance

Current LPDDR4X draws 0.6 volts. Compared to the new LPDDR5 option that draws 1.05 volts. They need to get that down. As a matter of fact they needed to get the LPDDR4X ram lower than 0.6 volts. I am all for speed, but if I can get a smartphone to last even longer at the expense of a slight speed reduction. Then give me the battery life instead. Especially since mobile SoC speeds are already up there.

LPDDR4 Voltage (Vddq) is 1.1 volts LPDDR4 I/O Voltage (Vdd) is 1.1 volts LPDDR4X Voltage (Vddq) is 1.1 volts LPDDR4X I/O Voltage (Vdd) is 0.6 volts LPDDR5 Voltage (Vddq) is 1.1-1.05 volts LPDDR5 I/O Voltage (Vdd) is probably 0.5-0.6 volts Samsung's is unconfirmed, synopsys' roadmap had 0.5 volts Also hence why Samsung claim their LPDDR5 is 30% more efficient than their LPDDR4X AFAIK Vddq is like the overal voltage, it has a far bigger impact on power consumption than Vdd But yea, would not be surprised if Qualcomm/S.LSI/Apple/Huawei go with Vddq of 1.05v (44 GB/s bandwith) for better power efficiency and lower costs/better yields while still bringing a great 47% bandwidth improvement

According to Samsung LPDDR4X provided 45% lower I/O power consumption But only 18% lower total power consumption as Core power consumption is still the same

just can" wait to see the samsung galaxy s10 models as to offer,keep up the good work Samsung,Apple will be in panic mode soon!

f**kING FINALLY! We've had very limited memory bandwidth gains over the past 4 years 2016 to now: 29.8 GB/s Q3 2014 to 2015: 25.6 GB/s Early 2014: 14.9 GB/s Hopefully 51.2 GB/s will encourage Qualcomm/Apple to make their GPUs wider -Qualcomm's has been the same size since the 820 (Early 2016) -Apple's has been the same size since the A9 (Late 2015)

why would Apple be in Panic Mode instead Apple will order samsung,,,,do this and that.

They'll skip it for 1-2 years. They'll wait until it's "cheap enough" for them.

You have to hand it to Samsung,they make the best parts in mobile today, without them a lot of technologies wouldn’t be possible. Today’s tech landscape is a mixture of google,Apple and Samsung technologies driving everything forward.

As i said in other threads, which Apple fanatics won't believe, Samsung is the king of hardware.

It looks like next year's Samsung phones are coming fully loaded! I have a feeling Sammy are gonna clean up next year! Apple are gonna need something special out of the hat! I can't wait to see what they all bring to the table, can we fast forward to 2019 please lol

Samsung temptation to Apple lol.

Hopefully they don’t artificially inflate the prices of these ones.

correct me if I'm wrong but, this would go on an SOC like the snapdragon 855/exynos 9820 which will be 7nm, along with the modem, gpu, and ufs so why would the ram be 10 nm while everything else is 7nm.... thats like having car with one wheel bigger then the other 3 it makes no sense so im willing to bet this is a proof of concept and will be remade smaller and more efficient for the snapdragon 865/exynos 9830

I think anandtech talks about this issue last year or two years ago not sure mentioned that Samsung Soc since 16nm,14nm and 10nm doesn’t build in the proper size!.

The ram is separate from the SOC otherwise every 845 soc phone would have the exact same ram configurations and manufacturer. In a vehicle analogy (which is not the best analogy in this case) the Soc would be the engine providing power, and the ram is the transmission.

Agree with you. But as anandtech mentioned that new Samsung Soc since 14nm till 10nm the base is 28nm not exctly 14nm or 10nm?!.
