Motorola X8 homemade SoC recap: modified Snapdragon forms 'the first true mobile computing system'

0. phoneArena 23 Jul 2013, 13:32 posted on

Motorola just joined the list of mobile device makers with their own homebrew ARM-based processor, called the X8. The actual name is Motorola X8 Mobile Computing System, and the dry facts are a 1.7 GHz dual-core application processor, 400 MHz quad-core GPU, a natural language processor core, and a contextual computing core...

4 Adreno GPUs in the same SoC (maybe Adreno 320 in multi-core?)
2 Krait CPUs @ 1.7GHz
2 small dedicated CPUs

Impressive graphic score in GLbenchmark

TO my knowlege, the Adreno GPU had one giant ass core with like 4 sub graphical units in it. However, it is four cores, it will have 16 sub graphical units. Its like how the Tegra 3 has a 12 core GPU, it is actually 3 cores with 4 sub graphical units per core. I think I explained it right, if not, someone correct me.

It is right and if we take this phrase as true

This SoC with is 4x Adreno xxx GPUs
"Egypt performance benchmark at a blazing 155 frames per second"

And the Nexus 4 (1x Adreno 320 @400MHz) does 44FPS
source:http://gfxbench.com/device.jsp?D=Google%20Nexus%204

It means that xxx is 320 so it could have 4x Adreno 320 GPUs :D!

I think what Birds is trying to say is that you can claim that Adreno 320 has 4 cores (sub graphical units) and that´s just what Motorola is doing. In other words: it´s just your old Adreno 320.
A modified MSM8960T in fact, and therefore the name: MSM8960DT

This "Old Adreno 320" (as you call it) can't do close to 4x times more...

Its one Adreno 320. The fps was based on the old 2.1 GLBenchmark Eygpt (720p). Even if it was 4x Adreno 320 would be an overkill for a 720p screen along with battery. No point even having a Adreno 330 if that existed.

Xzibit version: Yo Dawg, I heard you like Adreno 320, So Motorola put more Adreno 320 in your Adreno 320.

Adreno 320 doesn't have individual units or 'cores'. It's built around an unified shader design. They probably used a beefier version with slightly more shaders but it has nothing to do with actual 'GPU cores'

Ok, thanks....So can you explain to me more about this stuff? I'm curious.

Unified shaders superseded the traditional separate units which used to be the norm before the advent of DX10. Basically GPUs used to feature 3 different types of units; vertex, pixel & geometry shaders. Qualcomm ditched that starting with Adreno 200 as the industry moved forward.

Other manufacturers like Nvidia do still however use the ancient design and their cores actually still contain those 3 types of shaders.

Mali GPUs older than the T600 series use the old design, and so does Tegra 3 and Tegra 4. So basically the more of those traditional cores there is (eg Mali-400 vs Mali400MP4) the better the performance should be, at least on paper.

Any modern PC GPU or Qualcomms's GPUs will instead feature 'stream processors' that are more optimized at handling modern graphics. Those are the 'cores' which are advertised as "CUDA cores" on Nvidia GPUs and "Stream units" on AMD. Most cards will have a few thousand of them. Qualcomm didn't specify how much of those shaders are used in their Adreno 320.

No, you're reading it wrong. It's just misleading marketing for the uninformed. It says 4 graphics cores. Pretty much all smartphones have had "multi-core" GPU's for a while, ever since the Mali 400 in Galaxy S2, which had 4 GPU cores.

Imagination has had about half the number of Mali and Adreno, because they build them differently, and Nvidia has had many more "cores", because they're also building them differently into "cores".

So it's just Adreno 320, is what I'm trying to say.

The natural language processor seems really interesting. Glad Moto is doing something different.

...So its really just a dual core? With different types of dedicated cores that should theoretically boost the overall performance to be close to that of a quad core? Either way, I like what Motorola/Google is doing and can't wait to see how the voice control stuff plays out over time.

It seems like a better, more efficient take on the BIG.little architecture. I think quad core processor is more accurate than dual but its really both.

I'm sure the spec trolls will end up breaking it down as such anyway, so essentially we have:

- Snapdragon S4 Pro 1.7 GHz dual core w/ Adreno 320 GPU
- Additional dedicated cores for the always-on activities.

Attempts by Moto to characterize this setup as a "quad core" are disingenuous/marketing-speak. This is a modified S4 Pro dual-core. That said, it sounds like a very well-optimized setup and plenty of power for folks like me upgrading from a Snapdragon S3.

"Attempts by Moto to characterize this setup as a "quad core" are disingenuous/marketing-speak. This is a modified S4 Pro dual-core."

That is what I was thinking after reading 'between-the-lines'. One theory that I have been wondering about is whether Moto went with the S4 Pro because of camera processing constraints?

It gets curious-er and curious-er.

And I meant to say "octa core", not quad. But overall it sounds a lot like the setup TI had planned:

"OMAP 5 SoC uses a dual-core ARM Cortex-A15 CPU with two additional Cortex-M4 cores to offload the A15s in less computationally intensive tasks to increase power efficiency, two PowerVR SGX544MP graphics cores and a dedicated TI 2D BitBlt graphics accelerator, a multi-pipe display sub-system and a signal processor."

Given the tight relationship Moto had with TI, I wonder if this was originally intended to be an OMAP 5.

Didn't TI announce their departure from the mobile SoC business? If so, one has to wonder why Moto chose to hitch its wagon to an orphan? Which is why I keep wondering if their SoC choice was driven more by constraints from the camera side?

Phones have pretty long development phases. TI confirmed it was leaving the mobile SoC business in September 2012. So Motorola might have started developing around the planned OMAP 5, but would have quickly switched over to the Snapdragon line. I read about the camera angle too, that it was optimized for dual core. I was just speculating as to why Moto ended up going its own way while everyone else went straight-up Snapdragon 600/800 this year.

TI never really left the mobile chipset business. A lot of people misinterpreted them. They were really trying to say they were going to shift focus away from the mobile chipset industry to focus on a more broad agenda. They also stated they weren't going to pour in the money into the mobile chipset business like they did in the past. While it is true you haven't heard of any smartphones featuring an OMAP processor, it doesn't mean that there still isn't a chance of one being offered in the future (at least according to what TI has said).

However, you could be right that this may have been based on the TI OMAP 5. The OMAP 5 was suppose to have: "Two ARM Cortex-A15 MPCore processors capable of speeds up to 1.7 GHz each".

To be fair, they never said they had an octa core processor. They said it was an octa core "Mobile Computing System."

Conveniently misleading the uninformed, who can't tell a core from a CPU from an SoC from a Computing System.

Verizon specifies it. On the Droid Maxx pre-order page, this is what it says under memory/processor;

Processor: 1.7 GHz Dual Core with Quad–Core Graphics, attention hub, & 2GB of RAM

Marketing boss marketing... If Sammy can call its quadCore CPU (since only 4 core will be live at a time) as octa, Moto is bold enough to call DualCore CPU as X8...

Come on its 8core only if we incl the four sub-core in GPU, 2 extra for things which they are going to use extensively for marketing again...

If Moto simply choose Snapdragon 600 like other manufacturers, they would have launch these phones 4 months ago. Moto doesn't have selling volume like Apple, so this self-design chip only has little benefit if not disadvantageous time consuming.

HUMA or heterogeneous uniform memory access more advanced than Motorola and google could do.GPU & CPU access memory in parallel mode,so we can eliminate the inefficient memory channeling..
