AMD "Renoir" APU iGPU Configuration and Platform Spread Detailed
AMD's upcoming "Renoir" silicon will be the company's most important, as it will sit at the heart of not just desktops, but also notebooks and ultraportables. A brilliant report by _rogame on Reddit compiles the chip's many iGPU variants along with iGPU device-IDs, and slots them in various platform variants. Renoir will target four key market segments characterized by TDP: 15 W ultraportables, 45 W mainstream notebooks, 65 W mainstream desktops, and 35 W low-power desktops.
As for the iGPU itself, "Renoir" was last reported as being a processor that combines "Zen 2" CPU cores with an iGPU that has SIMD machinery from the "Vega" architecture, but with updated display- and multimedia-engines from "Navi." According to _rogame, Renoir's iGPU will have up to 13 NGCUs, which work out to 832 stream processors. AMD internally marks the iGPU as RV B##, where RV refers to "Radeon Vega," and B## referring to the iGPU variant. The commercial name of the iGPU will be different. B12 is the highest variant, with 12-13 CUs, B10 has 10-11 CUs, B8 has 8-9 CUs, B6 has 6 CUs, and B4 has 3-4 CUs. The B12 configuration will be exclusive to the mobile parts. The desktop parts cap out at B10. Renoir is expected to dominate AMD's processor launch cycle through the first half of 2020.

Maybe it's because 10th Gen is too new to have propagated through the distribution channels still, maybe it's because there are genuine supply and yield issues that Intel isn't talking about.
I am cynical of Intel because they've been caught lying and with their pants down so many times now when it comes to 10nm, but I'm actually not sure about this. There are enough 10nm products out with reviewers and youtubers that it may be approaching a real launch to the public, rather than an ultra-low-volume marketing stunt to keep the shareholders and investors duped for another year.
By the time "eventually" hits Intel will have their 7nm Core I series out and AMD will have lost the process node advantage. If AMD just keeps waiting, intel will catch up again (just like with athlon 64) and AMD will become a permanent also-ran for another decade. Again. The mere existance of the G7 shows intel isnt just sitting idly, they are working on an answer for AMD, and AMD should be doing everything they can to make thir mobile parts attractive to buyers, since power usage is out the window AMD should be exploiting their performance advantage, that means supporting memroy speeds from 2019, not 2015.
As I wrote before, AMD should have released the 3000 series APUs only once 7nm was ready, with rDNA chips. They would have been more competitive then these re-heated 2000 series parts are, and slotted intel as second fiddle even with 10nm G7. They will never get considerable market share if this is how they treat said market. Ahem.

Are you telling me those power numbers are solely due to intel's troubled 10nm arch? Reminder, MS worked with AMD to make the AMD surface, so if this is the best AMD can do, either AMD is completely incompetent or LPDDR4X has some impact, especially on idle power use where LPDDR4X pulls insignificant power compared to DDR4.
Clearly the Intel Surface Laptop beats the AMD in battery life, but the grey and red lines at the bottom of this graph are power usage in Watts. AMD seems to have both lower idle and peak power use compared to Intel, and the memory power usage is covered by the CPU power consumption, since the memory controller is on-die for both AMD and Intel.
Either:
Yes, AMD doesn't support something that is found in less than 1% of laptops out there because they've concluded there's no point in doing so with their current situation and market share and no one can blame them. You know what will change if AMD starts shipping APUs that support faster memory ? Nothing, all manufactures will still happy fit a a cheap ass single channel 2400Mhz module in there because they care far less about this than you do. Yeah because TSMC will just disappear or something. Intel's leading process technology keeps falling behind for a couple of consecutive years now and you're sitting here telling me they'll somehow have the upper hand. Sure thing buddy, I have to say this blind belief in team blue is staggering. A laughable series of assumption you make there mate. Let's list them out :
MS worked with AMD but Intel ... didn't ? They just sort of like put an Intel chip in there without them knowing or what ? What makes you believe AMD received some sort of special treatment ?
LPDDR4X has some impact but can you prove it's a major one ? Do you just ignore the fact these are two completely different chips from different manufactures on two different nodes by the way.
Yeah, it must be that AMD is incompetent, it couldn't possibly be the fault of something else like Microsoft for instance, the ones that actually designed and put together the bloody thing.
You know, instead of wasting your time like this pulling out arguments from thin air you can just reply with "AMD bad Intel good", we'll get the message.
High refresh is still difficult for display controllers simply due to the amount of time the controller is on submitting frames to a panel refreshing at 120Hz. It doesn't really have a chance to idle. If aggressive power saving was employed with high refresh, you'd likely encounter sync issues and intermittent loss of signal. Bandwidth of DP1.4 cable is maxed at 4K120 using RGB 4:4:4: 32.4Gbps. DSC must be used to achieve higher than 8bpc.
AMD's display controllers are connected via Infinity Fabric in Vega and Navi via GPU SoC circuit. In Vega, display and media ASICs can access memory independent of GPU via IF/SoC domain. Navi might be similar, but to counter increased latency of GDDR6 (vs HBM2 in Vega), it may need to use maximum memory clocks, which increases power draw at idle.
Dual 1080p monitors or notebook screen + monitor is how many laptops are used on daily basis (and TPU's test is fairly close to that).
It's just weird that a company would launch a SoC that has problems with such an important scenario. Dialed down and without SMT.
4700U benchmarks have leaked already - it's slower than existing 4C/8T Ice Lake U.
For the time being lets treat Ice Lake as pre-production TL. :)
And what do we know about TL? Expected to be 20%+ faster in CPU component and maybe 50% faster GPU (purely based on CU count).
Do you think there will be such a large gap between APU's ES and production?
Moreover, mobile Tiger Lake will have PCIe4.0 and all the goodies ICL already added. :) Could be true. Why wouldn't they? ICL is not a successor of CML. They are 2 architectures on different nodes existing side by side.
And, clearly, both lineups are being improved. They're both quite polished and fast. I'm not sure why you're trying to turn this into Intel's failure. :) 3780U is still Zen+. 4000-series will be Zen2.
VEGA IS SHIT uARch, not worth my $$$$$$$$$$$$$$$$ F**K DAT
guess its not gonna be till 5 or 6000 series apus.. im just sticking to discrete GPUS and Desktop 8+ core CPus, screw this..
wish a could take a zen 2 apu and customly add my 5700xt die into it myself... for one intels icl is 10nm, and amds 3780u is 12nm zen+ this is not a fair comparison by anymeans, they needed zen2 4700u in the surface 3 to actually campair intel/amd cpus sncenc TSMCs 7nm and intels 10nm are kind of equal ir Similar in efficiency..
