If the Ryzen 5 integrated graphics can produce that level of performance,then what about the Ryzen 7 integrated graphics which has 25% more CUs and a 20% uplift in clockspeeds??
It would be even more memory bandwidth limited than 2500U - unfortunately, DDR4-2400 is definitely not enough.
Honestly, I'm disappointed that AMD have decided to not support LPDDR4 or maybe even LPDDR4x up to 3200 MHz because without it they left quite a bit of IGP performance on the table.
I presume 2700U could be relatively close to MX150 using LPDDR4-3200 and with proper Vega drivers.
then how much ? give me a link, did you read my link ?
The fastest available DDR4 modules for Laptops are DDR4-2800 by G.Skill. But that's an overclocked module. The official maximum speed seems to be 2400. You can't expect a manufacturer to put a overclocked module. The Intel chips don't support higher frequencies either.
The best LPDDR module support seems to be LPDDR3-2133, with no existing CPUs supporting LPDDR4 of any format. It is puzzling why Laptops that cost more and demand higher performance have lower speeds than Tablets, but that is how it is.
My guess is that Tablets don't need very high capacity and going higher than that is a tradeoff that results in lower speeds. Laptops require, 8, 16, or even 32GB capacities, and modules going into Laptops need to take future capacities into consideration.
Yes I've read your link. You are unable to understand that the power draw from a notebook isn't GPU
exclusive. Or do you think the CPU, LCD and all other components are for free?
Ryzen 2500U consumes up to 25W also MX150's TDP Is 30w and any notebook with Geforce MX150 will consume up to 77w ( Abwx's post )
Exactly, that's a 5W difference with twice the GPU gaming power. I would suspect that Ryzen 2500U configured with 25W goes well above 50W for the entire notebook for the same metric.
Even the passive cooled desktop versions of the MX 150 (GT 1030) peak at ~33W during torture testing.
And the MX 150 is operating at 290MHz lower frequency (937MHz vs. 1227MHz).
I would be surprised if the MX 150 power draw ever exceeds ~20W, since most likely there are also other tricks present than just the lower clocks.

Raven Ridge lucked out in that sense as when it was first being conceived I imagine Intel's plans hadn't changed yet.The reason LPDDR4 isn't supported in laptops right now is because Intel is the main vendor of laptop CPUs and its processors have used the same basic microarchitecture as Skylake for the last few generations, meaning that the memory controller didn't get updated to support LPDDR4.
Had Cannon Lake and Ice Lake been on time, LPDDR4 transition in notebooks would've happened much sooner.
Picasso however better support LPDDR4, don't want to be left behind once Intel releases Cannonlake.
Mostly because having LPDDR4/3 is most likely a requirement to be in Apple laptops.How exactly would LPDDR4 support change anything?
They are available at higher frequency than DDR4 is, however the SoC still needs to have a memory controller IP and a power budget which can actually utilize these higher frequencies.
LPDDR4/X is already available at higher speeds than the memory controller in Ryzen CPUs & SoC can support in practice.
Exactly. In some tests there is a power draw of 35W in Witcher 3 gaming for the entire notebook. No chance it consumes more than 20W in these notebooks because the LCD and CPU SoC requires quite a lot of power too.

Where on those links is the evidence supporting your position?
Giving under load med numbers of near 70watts doesn't seem to align to your position. In fact on there measurements we can do some extrapolation:
Given the power draw it seems more like a 25W processor
FPx?Like a 25W processor?
It essentially is a 25W processor, since all 15W TDP FPx infra parts are allowed to consume 25W until certain temperature limit is reached.
When or if the limit is reached, depends on the physical characteristics of the system and the software configuration it uses.

Notebookcheck is finally starting to review the Envy. Given the power draw it seems more like a 25W processor but it can also sustain the Cinebench R15 benchmark much better than most of the KBR models. It's obviously way faster than the UHD 620.
Power consumption results are just as incredible for Our Ryzen 5 model. The AMD HP notebook manages to be less demanding that the Spectre x360 15 with the i7-7500U CPU and GeForce 940MX dGPU while providing a roughly 50 percent boost in multi-thread CPU performance and 20 boost in GPU performance. The performance-per-Watt is even more impressive when compared to AMD's own demanding mobile RX 460 GPU.
FPx?
