I think AMD's CU's are with 64 Shaders, so 640 shaders total for the 10CU, and 512 for the 8CU ? The 2700U showed up to 1300MHz I think for the GPU core.

You're right! And dual channel vs single channel, I wouldn't worry a whole lot. APU's in the past haven't seen huge gains in single channel vs dual channel, only in memory sensitive applications like 4k rendering or data crunching. Same thing with Ryzen vs Threadripper too.

Its on the slides for the three "launch laptops". It does look like Lenovo is launching only with Single-Channel DDR4-2133 support, and both HP and Acer state Dual channel memory, but only "Up to 8GB" without stating whether thats per channel, or in total. AMD's reference setup does have 2x4GB of DDR4-2400 though............

I have gone 3 times through slides and i have to say fsck my eyes 🙂;),until you didn't mention it i didn't saw it (still needed it to enlarge page to see properly):):)

APU Gamers (there might be some out there 🙂) would love dual channel memory, so would the on-board vega. 😉

Looks like there are two sets of slides going around. Arsetechnica has slides that show the TDP to be 12-25W, and most others have 9-25W (Configurable), while both have 15W as the nominal power draw....

I'm curious to see what the benchmarks would be at various stages of the configurable power draw. How much does it benefit from using 25w vs 15w etc....? Pricing and retail configurations aside, these look quite compelling if anyone's in need of a super mobile device with enough oomph to game a bit (or do 3D related work of course).

It would be interesting to know the compute power of the GPU part... how many GFLOPs ? It would also be nice to compare it to Intel's HD 630. Is it Christmas yet?

AMD's site claims 12-25W configurable, and our Dell rep confirmed that for me as well.

When I had my ASUS laptop with a Core M, honestly even with gaming I never noticed any performance issues running 2 cores. Games like DOOM, Skyrim SE, ESO, never had an issue playing them.

Assuming your laptop had an i7 M series, why didn't you just save yourself $100+ and get an i5 for roughly the same performance? Or was the GPU you wanted only offered on i7 models? Because if you were limited by GPU then I can definitely understand going for the i7.

While I don't know the particulars of his case, typically products that used M/Y series Intel processors with a 4.5watt TDP didn't have options for higher drawing U-series chips. When you're getting that small, it's a world of a difference between 4.5watt and 15 watts - roughly 400% increase in wattage, and power/heat doesn't necessarily scale linearly.

Not bad at all. Could give Intel a run for their money in the CPU department. As far as graphics go AMD is all ready ahead of Intel in that department. Makes me wonder if they are going to make 6 and 8 core versions of the these.

Well if they get the pricing correct I would buy a new laptop with amd inside.

Im almost certain we won't see 6-8 cores in the laptop SOC segment until AMD gets on Gloflo's 7nm process then its entirely possible staying in the same TDP ballpark.

That could very well be a possibility. Either one could happen.

If there is any video memory carved out of the system RAM, then dual channel really has a big impact when playing games.

AMD has amazing APU's in my experience with them I just wish they could release one with a gpu the size of what they have in the consoles then we would have a beast. Though now that I think about it the ddr4 system memory probably couldn't feed the gpu anyways so it's maybe not worth going crazy on the gpu core.

I am really looking forward for this release , looking good !

I think one of the main problems with this is the fact that these will, most of the time, go into laptops, which have a lot less cooling capability then a console case. It's likely better, for cooling, that if you want a CPU with a decent GPU, that they both be different entities and can be cooled separately (or combined with a larger heatsink/fan assembly). No matter the configuration, it has two parts contacting the cooler. But also, cost. APUs are meant to save money but also get good performance from both your CPU and GPU. The saving money part would be thrown out the window. Last i checked, the PS4 APU costs nearly $200 for sony, and i'm certain that's after at least a small markup from AMD. To a consumer, that would probably mean $300-400+everything else you'd be paying for (plus markup) on for a laptop. Even more it'd likely be more then $300-400, because of the fact that $200 is based off of quite old tech, not ryzen etc. That'd likely be a $1200+ laptop on the low end of configurations, and you wouldn't even, technically, get a dedicated graphics card with that.

So happy I waited after I sold my last laptop ! Now I will be able to grab a cheap new one that can actually game !

The PS4/Xbox chips are custom designs for the customers. They can't be binned and sold elsewhere. Thats why they are so costly. These mobile Ryzen chips may be a bit expensive at the start (but nowhere near the PS4/Xbox costs), due to low yields, but the price will get better with binning, and better yields. Cooling efficiency is due to the die surface area, the larger the die, the easier to cool it, but the more cost to fabricate. Having dual chips in a laptop is always going to be more expensive than an APU, because you have a more complex cooling system, and a more complex power distribution, equating to a much more complex and costly motherboard. These chips are made for relatively simple laptops. If you want more GPU power however, you might be able to add an AMD GPU, but i think AMD will probably shrink and beef up the CPU/GPU combo for Ryzen 2 on 7nm, rather than add a costly GPU. Its probably up to vendors to add an external GPU if they want, so we might see some...

Good stuff, it was quite odd seeing Intel hold the 'APU' crown with their iris/iris pro parts (I game on an Iris 6100, yes, it's good enough!) having not only equitable GPU grunt but much better CPU cores vs pre-ryzen parts. Ryzen has proven itself a good'un, but Vega is a power hog when pushed on the desktop, hope it's better in low TDP roles.
