I've read conflicting information about this, but I was wondering, what type of architecture does the Processor(s) in the Nexus 10 use?
Most places list it as dual-core, which I'm assuming just means 2 cores on 1 chip. Some places and people mention 2 separate CPU's (as in, 2 separate A15 cores)
Which is it? For some reason I kind of like the way 2 separate cores sounds...
It is a Samsung Exynos 5 5250, which is a dual-core A15.
Two cores, one chip.
Here's a link to the ARM Cortex-A15 Wiki page.

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

The Nexus 7 has a quad-core tegra 3 with 4 cortex a-9 cores while the Nexus 10 comes with a dual-core exynos 5 with 2 cortex a-15 cores. So which chipset is more powerful? Cortex a-9 is less powerful than the a-15, but there are twice as many cores, and it kind of confuses me why Google would go with a quad-core for their tab, but dual-core for their full-sized tablet. Thanks for the answers, I don't know whether I should keep my nexus 7 or trade it in and buy a nexus 10 when it's released.
The a15 dual core murders our tegra 3.

The Dual Core Exynos is "better". But they are two completely different products with completely different functions. So just because the N10 has better hardware doesn't tell the whole story.

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."

Here's some disucssion of Teg4 from a chip forum. People who do chips for a living aren't impressed; especially with the GPU.

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
Samsung has just announced an enhanced version of its Exynos 5 Octa chipset.
Currently the Octa chipset is available only on the I9500 Galaxy S4 flagship.
The second generation Exynos 5 Octa might be called Exynos Evolved and it will be more powerful, enhanced Exynos 5 Octa".
Speculation calls for the new chip to be the Samsung Exynos 5420 and will feature a higher clock speed along with improved optimization for the 8 integrated cores.
Stay tuned for more news next week:highfive:
They really shouldn't call it octa cores and it doesn't have a solid 8 cores. It has a 4x2 core structure.. With two solid four core processors, not one eight core one.
Wrong forum,It's galaxy S3 forum section,Exynos 4 not 5.

It has 8 cores inside it, might as well call it octa

Agreed. Read here The HMP processing does require all the 8 cores available online.
Misconception #6: Yes the CPU is a true 8-core processor. It's just not being used a such in its initial software implementations

The to-be-announced new processor is the 5420, it's not a new revision of the 5410. It has the same target clocks as the 5410 but with a properly working CCI to be able to use GTS, and the GPU is replaced with a new generation Mali T62X instead of the SGX 544. It also has some other miscellaneous updates like VP9 encoder/decoder. It'll debut in the new Chromebook this fall.I already know the differences. In any case - it's not useful in regard to the 5410.

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.
