Simple question, I purchased a Moto G GPE and its on its way but i have the curiosity about how the SOC Snapdragon 400 Cuad Core compares to something like the S4 Pro that was in the Nexus 4 which ran great. I know its a newer chip but i havent found any real evidence whether the architecture is superior or inferior to the S4 Pro since it was a flagship chip but the 400 is budget. Anyone has any insight on this? Thanks.
best way to compare the two.

Snapdragon 400 is positioned more like S4 Plus, not Pro. As in marketing positioning.
Speaking in technical terms however, those two SoCs have a completely differnet architecture. S4 Plus always has Krait cores, while our S400 has Cortex-A7 cores, which is generally somewhat slower than Krait, partially because Krait is an Out-of-Order architecture, while Cortex-A7 is In-Order.
In terms of cores S4 Plus always had two cores (up to 1,5 GHz), while our S400 has four cores @ 1,2 GHz.
Now go figure what´s faster. I´d personally prefer two Kraits
Note: Qualcom had really messed up the naming in S400 series as the chips can contain either two Krait cores or four Cortex-A7 cores. Don´t get me wrong, Cortex-A7 is a great architecture , mostly because its performance/power consumption ratio, but the SoCs containg those cores should have been labeled as Snapdragon 350 or something like that.

The real world performance of the Hummingbird is superior to all other ARM Cortex A8 processors I have found. Of course, that won't remain that way when CPUs like the Tegra 250 start coming onto phones like the LG Optimus 2x.
Yea the Tegra chipset will blow everything out of the water . I do like the Hummingbird processor though

No, that will remain even after Tegra 2 comes out..simply because Tegra 2 is Cortex A9 lol
Its no surprise the Hummingbird is the fastest processor...originally the TI OMAP held the crown of pushing the Cortex A8 to its max..Samsung with TI OMAP in mind went a step farther to try to create something even better (despite many telling them its not possible)..and with hep of Intrisity the Hummingbird was made which pushes Cortex A8 beyond its limits..
The Hummingbird is the king of 2010..and it was made it 2009..it is only fitting that next year in 2011 a better processor comes out, and then a better one in 2012 and so on...

Hah, you guys sound like you've read my article. Or maybe I'm just flattering myself.

Anyhow, there's one major problem with the article linked by the OP; that test is soley a GPU test, not CPU. The PowerVR SGX540 is, without doubt, the fastest GPU on the market today.
The Hummingbird does just barely edge past Snapdragon MHz to MHz in side-by-side processing tests, though any 1.x GHz OMAP / Snapdragon does have the 1 GHz Hummingbird beat (except when it comes to GPU performance, obviously.)
Where the Hummingbird starts to lose out MHz for MHz is in Android 2.3 where the JIT compiler was optimized for Snapdragon (and I assume OMAP) processors. Hopefully we'll see this change and Google work some better Hummingbird support into Android with the release of the Nexus S; now the flagship "Google Phone".

I actually researched this info back before CTIA when the Hummingbird was first announced...but I do remember stumbling upon your article here and there.

Even with 2.3 optimizations I do not think an old 1st gen 65nm Snapdragon will outperform a Hummingbird mhz for mhz..the newer 2nd gen ones are another story.
But yeah, optimizations from the Nexus S would be sweet..while I was hoping for an Orion CPU, I am quite happy they chose the same CPU as ours, this will help development a lot...
Is it true that Qualcomm's dual-core CPU's will be based on the older ARM Cortex-A8 architecture set instead of the modern Cortex-A9 which is being used by Apple's A5 Chip and Nvidia'S Tegra 2 ?

The hardware benchmarks on the dual-core MSM8x60 1.2 Ghz chip used by HTC Pyramid (Sensation,Doubleshot) and the Evo-3D do not look pretty good.

Need a bit of clarification on this issue why they didn't choose the Cortex-A9 path.
Ok so I just read this report from Qualcomm explaining this issue:
http://www.qualcomm.de/documents/files/linley-report-dual-core-snapdragon.pdf
Apparently their architecture set is compatible with ARM's instruction architecture set and they claim its better than the A9.
"The superscalar CPU uses a 13-stage pipeline to generate faster clock speeds than competing products can achieve using ARM’s Cortex-A8 or Cortex-A9"
Having said that still not sure why the hardware benchmarks are not near the Cortex-A9 dual-core processors.
Adreno-220 is pretty good though compared to other GPU's.

Because bechmarks are meaningless and HTC have yet to put the work into fiddling them yet!
Quamcomm has been claiming that their design is better than ARM's Cortex A8 before but other than few special occasions, they are mostly equal at the same clock speed. Since MSM8x60 is also based on the identical cores, I don't see how it could be better than Cortex A9. In fact, Qualcomm is working on their own "equivalent to A9" version right now.
FYI, # of pipelines don't tell the whole story about the speed of CPUs. If not implemented well, it will simply cause longer stall delays. We have seen this in the old Pentium 4 architectures.
I think the 128bit fpu makes scorpion equivalent to a9 in floating points calculation

Looks like a winner to me!
In comparison to iphone 5 which also uses A15 cores and a triple core powervr gpu
http://www.glbenchmark.com/phonedetails.jsp?D=Apple+iPhone+5&benchmark=glpro25
and the Lg Optimus G which has kinda like A15 architecture plus an adreno 320 gpu,
http://www.glbenchmark.com/phonedetails.jsp?D=LG+E970&benchmark=glpro25,
the samsung dev board with the dual A15 [email protected] and the all new Mali-T604 gpu beats both of them holding the highest score so far!
Way to go sammy!

Samsung just launched a new processor line up called Exynos5 Octa the story is still developing but the following are some details that are out
Samsung unveiled a brand new processor that will power its future mobile devices. Dubbed “Exynos5 Octa,” the new chip features two sets of four cores and a 28nm process that will eventually drop down to 10nm in the coming years. The chipset provides significant performance enhancements over Samsung’s previous-generation quad-core Exynos processor, which is now found in more than 53 million mobile devices. The company also said that the new Exynos5 Octa has a power-saving mode that helps improve battery life by reducing consumption when devices are idling and in other situations where full processing power is not required.
So between Exynos 5 Quad which is an A15 32nm chip that's supposed to be used in the SGS4, Krait v3 which is 15% faster version of S4 Pro, and now Octa, Nvidia may as well pack up their marbles and go home.
For geeks, here's some details on Exynos 5 which is Samsung's current "state of the art."

Watch out. Demandarin might come around and tell us how great the Tegra 4 is Youg looks good, I wonder if it will be involved in devices before August 2013

8 cores..wow...overkill.
It wasnt long ago (less than a year?) That reviewers were stating quad core is abit of a gimmich right now on phones and tabs etc.
Im all for it ofcourse..but wow 8 cores
The 8 cores will be device into 2 sub 4 cores - 1 sub 4 core will be an A7 1.2GHZ quadcore processor for lighter task and the second sub core will be 4 core A15 1.6GHZ of above quadcore processor.
The same will be built on 28 NM technology and later 10 NM technology over a period of time.
Again these are not confirmed specs
So the Qualcomm Snapdragon 820 is quad core. Why did Qualcomm decide to go with a quad core one over a octacore or hexacore? How would that affect the GS7/GS7 Edge if it were octacore or hexacore? How much of a difference is there between the Exynos and 820?
Indeed the snapdragon 820 is a quad core SOC unlike most recent socs which have featured 8 cores (2 clusters of 4 cores). However most big.little socs like the exynos 8890 and 7420 use 4 low power slow processors and 4 high power, but power hungry processors. They are completely different architectures. This means that while the exynos 8890 for instance has 8 cores. Only 4 of them are really designed for performance. The other 4 are designed to save power. The 820 is different. It's also some sort of big.little setup with 2 clusters of 2 cores. However both clusters are identical architectures. The difference is one cluster is clocked lower and has a different l2 cache configuration in order to use less power. On top of that the custom cores in the 820 are faster per core than the exynos 8890. So clock for clock the 820 would win against the high power cluster of the exynos. In heavily multitheaded situations though. The exynos still can tap into all 8 cores at the same time which should give it an advantage in that scenario. For the rest of the time I would imagine the 4 faster cores of the snapdragon would be better suited to everyday stuff. As for why they only went with 4. My guess is cost, and power efficiency. Kyro is a brand new architecture. Krait went through many iterations. Kyro will probably see a noticeable reduction in its power envelope in the next iteration which would make shoving more of them onto an SOC a more viable option. As for gpu, all signs are pointing to the snapdragons adreno GPU beating the Mali in the exynos atm. Development will also be improved on the snapdragon device as Qualcomm releases the proprietary vendor binaries and Samsung does not. This means the likelihood of seeing cm or aosp on an exynos variant is slim. Hope this helps!
Actually, the Kryo cores are (slightly) better at running single threaded tasks while the Exynos cores are (slightly) better at running multi-threaded tasks. I doubt the everyday users will notice.
The Adreno is also more powerful than the MALI GPU, though everyday users will mostly notice a performance improvement on applications using the Vulkan API vs regular applications, than anything between both these GPUs.
Finally the memory management seems much better on the Exynos 8890 for some reason (about twice as fast), since the same chips are used I wonder whether it's a software or a hardware implementation difference, both units are plenty fast though.
The real difference between both these SOCs will seen in the power management efficiency, in fact both variants are overpowered in every aspects as far as regular usage goes, so there is little point in comparing which one's the fastest. Instead, you need to wonder which one is the most conservative with power consumption while achieving equivalent performances.
Both the GPUs on these SOCs support the Vulcan API. And, whilst the Adreno is faster in terms of pure benchmark numbers, I very much doubt there will be a noticeable difference on any game or application, Vulcan or otherwise, that will be released during the lifetime of these phones.
Yeah, that does help explain it. Thanks. I just hoped there wouldn't be a TSMC vs Samsung difference in the iPhone 6S/6S Plus SoC.
i was thinking 8 core snapdargon 810 was over heating and thermal throttling so they went for 4 cores instead on snapdragon 820.
just my thoughts.
