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

Just heard out of blue and read somewhere on the forums that some companies are planning on dualcore.
Just curious how true is that?
dude.. wrong place to ask this.
But... Yea its true. There are some 'dual core' processors out there now, but its mainly one GPU processor and a CPU processor.
Ive read somewhere that Qualcom are planning on makin a true dual core cpu ;-)
I think that they should hold off. 1Ghz is fast enough. We have not meet 2Ghz yet. In my opinion a dual core phone would be too powerful!!! But in many cases it would be a nice option. Everything would be instant and they would have to increase the nand and ram speed. Imagine, a phone with 0 lag with no matter what you do.....
think of the battery life with 2GHz processor!

They would probably find something more energy efficient - like the Intel N450 processors as opposed to its predecessors.

the processor behind every dual core chipset.
samsung announced releasing a 1ghz dual core processor for early 2011 , as well as qualcomm started shipping its 1.2 ghz dual core processor , but not yet applied on phones but is said to be in early 2011 too, but the qualcomm 1.5 was delayed for the end of 2011 , that is all the info i collected about dualcore processors

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.
http://alienbabeltech.com/main/?p=17125
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...
Sets the bar at 2GHz
KOREAN HARDWARE GIANT Samsung has announced its latest processor, the Exynos 5250 that is based on the ARM Cortex A15 design.
The dual-core processor is designed for high-end tablets and will run at 2GHz. It is fabbed on a 32nm process and is set to appear in devices in the second half of 2012.
"The ARM Cortex-A15 brings unparalleled performance to our Exynos processor family and the exploding mobile marketplace," said Dojun Rhee, VP of system LSI marketing at Samsung. "The advanced low-power, high-performance processor technology of the new Exynos 5250 continues to deliver an unprecedented level of performance for users to enjoy a completely new mobile experience."
Samsung claims the new chip can process nearly twice the number of instructions per second as the ARM 1.5GHz Cortex A9 chip. The Exynos 5250 will be able to support up to 2560x1600 resolution displays and will have four times the graphics capabilities of the Cortex A9.
To support this high resolution the chip has a doubled memory bandwidth of 12.8GB/s compared to existing chips, which also aids data processing speed. To help with power efficiency the Exynos 5250 also has an embedded Displayport (EDP) interface that is compatible with panel self-refresh technology (PSR). It allows a static image on the screen to be refreshed from a memory buffer instead of using processor cycles. µ

If that chip is in the Galaxy Note 2.....
I will never turn it off.

Exciting news, just as fun as way back when when following dual core PC chips move to quad core and the drool factor they had. I personally hope ARM keeps up this arms race so fast that x86 never has a chance...
Low cost, low power, high performance, small footprint.
This time next year is really going to be exciting...
Just when I had started enjoying my Galaxy Note :|
Its second half of 2012, long time till then.

The future generation Samsung processors looks like to be beast an 8 core processor for a tablet or a mobile is from a scifi movie
please read this article to find out more
Samsung's processor design team has been on a roll with fast chips this year with the Exynos 4 Quad and Exynos 5 Dual. Based on its agenda for the International Solid-State Circuits Conference, that momentum isn't about to stop. A company presentation at the event on February 19th will delve into a new heterogeneous, 8-core processor that relies on ARM's concept of big.LITTLE computing: one half is a quad-core, 1.8GHz ARM Cortex-A15 that will do all the heavy lifting, while the other is a quad 1.2GHz Cortex-A7 that takes over in quieter moments. We don't know much more about the chip beyond the expected 28-nanometer manufacturing process, but it's easy to see a mobile chip that's fast without having to consume much energy in its downtime. Most of the mystery surrounds where Samsung will launch the processor first, rather than what it can do: the big.LITTLE chip would be most valuable in a smartphone, but a potentially large size could relegate it to tablets early on.
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.
