What should the TDP of the next optimized for mobile AMD APU be?

[cbn]

EDIT: the fifth option was meant to read "115W to 130W" instead of "115W or greater".

By "Optimized for mobile" I mean voltage and clockspeed meant to achieve the best performance per watt possible. (Eg, With Kaveri APU this was 35W.....while the 65W to 95W desktop APUs (using the same processor die) had lower performance per watt)

Raven Ridge is 35W (with option to 45W, I believe)

Kabylake-G is 65W.

GTX 1050 (laptop) and 45W Intel processor = 85W to 95W. (Note this convertible is the first GTX 1050 mobile device I have found to use a 15W Intel quad core processor, so that would make total TDP (of CPU and GPU) 55W to 65W)

GTX 1060 (laptop) and 45W Intel processor = 125W (or 105 to 115W when the GTX 1060 is in Max-Q trim)

GTX 1070 (laptop) and 45W Intel processor = 160W (125W to 135W when GTX 1070 is in Max-Q trim)

As a point of interest and reference here is the cooling of the MSI GL62M 7RD, A 15.6" 45W Intel Core i5 + GTX 1050 laptop currently $650 After rebate at Newegg:

It would also be good to see some kind of optional cTDPdown (or a cTDPdown state).

Examples: 120W APU at 50W (or 165W APU at 70W) would be the same proportional relationship as a 35W APU configured at 15W.

I personally prefer 20W max. Anything higher either means high noise levels or increase in the system size and weight.

Mobile Raven SKUs will be available in many different TDP configurations, ranging from 12 to 54W.

On desktop (AM4) they're probably available in 45W - 95W configs.

You are missing the 15W to 35W option.

130w under full load - 15w idle - with the i7 and 52db is imo to high for my usecase. And also shows tdp ratings is meaningless for evaluation and that i7 plus 1050 is on another planet for power. Cant compare them.
But the 35w tdp limit of my current thinkpad t460 chassis seems fine. So i take that or perhaps 45w. Dont need the 15w of my former 900 series samsung that was like 1 kg. Lol.

Can you disclose that, this early, or it's just a guesstimate?

The 2016 Razor Blade (14", 4.32 lbs, 45W Intel CPU and GTX 1060) got 51db from the same review site:

https://www.notebookcheck.net/Razer-Blade-2016-Notebook-Review.186751.0.html

But listening to the following video of the same laptop (running Heaven Benchmark) it didn't seem that bad to me:

Indeed, and below. This list is more for what has become the new desktop with a lid.

 

[ao_ika_red]

There should be 5-15W option. A light, cheap, and long-lasting notebook.

Obviously I have no official info, only a gut feeling

An ARM SoC?

https://www.qualcomm.com/news/onq/2...agon-835-mobile-pc-platform-unveiled-computex (5W TDP)

https://en.wikipedia.org/wiki/Tegra#Tegra_X2 (7.5W to 15W TDP, not sure if can run Windows 10.....but I would think with Snapdragon 835 running it Nvidia shouldn't be too far behind)

Nope. Ever see Intel's Apollo Lake in action? Its TDP is 6W and runs just fine on Win10. You won't game in it, but certainly it's enough for students and office workers.

 

[Schmide]

APU should be 15w at this point.

 

[IEC]

DTR or bust. My current laptop is a 15.6" DTR with a 6700HQ + GTX 960M. It's a wee bit underpowered for my usage.

Here is what's crazy, the new Surface Pro has a Core i7-7660U that has a 15 watt tdp rating. That's a dual core chip.. RV Ridge may have a lower tdp (impressive considering AMD had been more conservative on their ratings) all with a quad core and Vega graphics..

Might make for some really great tablet gaming machines!

I don't think 12W will be enough to fully power up both the CPU and iGPU of Raven Ridge. In fact, I predict the silicon (at these low TDP levels) to go mostly underutilized when used for gaming...so the quad core advantage (vs. dual core of Core i7 7660U) may not help. (EDIT: With this mentioned a quad core low TDP APU should allow (for games that are able to spread the load out to eight threads) a bit more energy to be used by the iGPU. This due to the increased energy efficiency of four slower cores vs. two faster cores)

The low TDP configuration is mainly for people using the device for certain content creation apps that either use the CPU (eg, Video editing) or the iGPU (eg, Blender Cycles)....but don't use both heavily at the same time.

Well, OP didn't specify what kind of usage is going to be. If 150W+ TDP on mobile APU is on the option list, there's no reason of <15W APU is not acceptable. It's about mobile APU after all..

I actually like the idea of 15W APUs* (based on the same die as the 35W APU) to some degree......but I also think AMD needs something more than this.

*Would like to see testing using creative apps (video editing, Blender, etc) when compared to 15W Intel processors using both GT2 ( eight generation processors with 4C/8T) and GT3e (like the 7th generation dual core Core i7-7660U, etc mentioned in post #16)

Regarding a purpose built 15W APU, AMD does have Stoney Ridge.

 

[cbn]

ASUS ROG Zephyrus GX501 (Intel 45W with Max Q GTX 1080).....so 135W to 155W for the CPU and GPU combo:

https://www.notebookcheck.net/Asus-ROG-Zephyrus-GX501-Laptop-Review.230546.0.html

Interestingly enough this is even quieter** (at 46 db) and lighter (4.96 lbs) than the GTX 1050 laptop (47 db*, 5.29 lbs) linked (and discussed) earlier in the thread. This despite both being 15.6" designs.

*52 db when set in fan turbo mode.

**It does getter hotter though. (Substantially hotter)

Actually, I'm looking for the spritual sucessor of Puma+ (Carrizo-L) APU that should be comparable with i3-5010u IPC and thread number wise. Stoney Ridge is not my taste because with just 1 module of XV core, there's not much you can do.

Depending on whether they pursue it for low TDP there may still the Branded Kestrel alongside the Great Horned Owl/Raven Ridge sometime:

 

[MarkizSchnitzel]

As low as possible to enable fluid browsing and fast app opening. So 5-10w is enough for me, and vast majority of other people, judging by core-m.
