Any smartphone will benefit. Idle power consumption with Snapdragon new power reductions, maybe we are going back to days where phone could last a week(if usage is low)
Depending on what you are doing...but it is the screen and CPU/GPU that hogs the power, not the modem...of course if you have the phone locked and not using anything, yes modem could consume the most power in the background, but really who uses phones like that?
Yep. AMD's (very nice!) iGPUs are seriously harmed by having to use power-hungry DDR4. A shame that they don't support LPDDR4, really, but if LPDDR5 is arriving this quickly, I suppose it might have been worth the wait? If support for this can be implemented in the memory controller of the next generation of APUs, that would be fantastic.
So this would be capable to offer sufficient bandwidth even for something like Vega11 in 7nm Raven Ridge if clocked at 1600MHz, for the resulting performance of ~RX560/GTX1050. 2.25TFLOPs and 100GB/s bandwidth.
AMD's Picasso had better bring support for LPDDR4 *and* LPDDR5. As cool as Raven Ridge is, they really need to make up for the abysmal bottleneck in power savings and raw memory bandwidth they have from not supporting the ULP memory standards.
A mobile-oriented SoC just can't be hindered by the terribly slow pacing of desktop+server memory evolution.
This is where Gen-Z would come into play. With Gen-Z, you just tie the CPU into the system bus and everything can talk to each other, allowing for much higher speed connections to memory or other devices. It remains to be seen if/when Gen-Z will actually make it into modern systems, but with AMD having been an early backer of the idea, I would hope for the new CPUs in 2020 to make use of it.
I noticed that nowadays, manufacturers of these high speed memory don't seem to disclose the latency. I sense in order to obtain these high memory bandwidth, a lot is being sacrificed in terms of latency.

Basically I want a new Nintendo Switch with this LPDDR5. My only use case for high speed mobile memory :)deil - Tuesday, July 17, 2018 - link

Pipe dream, it's the modem that is the power hog not ram or a CPU, put the phone is airplane mode and it'll last a week with little usage.french toast - Tuesday, July 17, 2018 - link

It would also be nice if it hits laptops this time around as they also benefit from lower power memoryValantar - Tuesday, July 17, 2018 - link

Yeah, this would be ideal for future Ryzen APUs. You could run 20 or 24 CUs on this pretty well.Xajel - Tuesday, July 17, 2018 - link
So when are DDR5 are actually coming to desktops/laptops ? last I heard was 2020/2021, is there's a more updated timeframe ?iwod - Tuesday, July 17, 2018 - link
LPDDR5 still only allow 64 Gbit? Please Please make it 128Gbit...ToTTenTranz - Tuesday, July 17, 2018 - link
