Just yesterday we heard that AMD is joining the mobile race big time, and today we know how exactly - with the newly announced ARM Cortex A50 cores…

Can ARM see Intel in rear window mirror?

In desktop space---NO.
In server space---NO.
In mobile/tablet space---Difficult to say.

"ARM is only designing the architecture while other companies like Apple, Qualcomm and so on build the actual chips."
I thought that Samsung builds Apples chips, Apple designs them or builds upon ARMs design?!

Apple designs the chips, Samsung builds them. Apple's A6 processor uses a similar instruction set to ARM Cortex, but it is a custom chip sort of like Qualcomm's Snapdragon.

In short every manufacturer uses ARM architecture while some like Apple & Qualcomm modifies the stock version architecture and Samsung,ST Ericsson,OMAP etc uses the same stock version to build the SOCs.

its abit complicated, this is from what i understand .. the whole chip is called SoC (system on chip).. SoC has many components, the ones usually talked about are the CPU (central or main processor which runs the operating system) and GPU (graphics processor which handles anything related to graphics,pictures,videos,games etc).. there is also RAM bunch of controllers and other smaller things in these SoC.. so for most of these companies like samsung, Nvidia, and TI use the CPU from ARM like cortex A9 in tegra 3 and pair that up with RAM, GPU and make the whole chip.. thats what it means that they design their own chip coz they decide to pair which CPU with which GPU etc. then these chip designs go to foundry's for fabrication and they r the ones who actually make the chip example of that are TSMC, UMC, samsung have their own foundry's etc.

also i should add that apple and qualcomm take up these CPU designs from ARM and customize them abit according to their requirement. and they are almost always sort of in between kind of thing. forexample krait from qualcomm and swift from apple are both in between ARM's cortex A9 and A15

Qualcomm SoCs have nothing to do (or in between) with the Cortex-AX family, they are totally different inside out and there is a huge difference when it comes to their internal components. Companies can't also integrate any kind of GPU into any random mobile SoC since each will only accept a specific GPU family. For Snapdragon you've got the Adreno, Exynos with Mali, Omap & Apple AX will opt for PowerVR and Nvidia uses their proprietary ULP Geforce solutions. Others like Vimicro will adopt the Vivante GPUs and so on.

i was talking about krait and swift being in between cortex A9 and cortex A15. in terms of architecture, design, performance etc

Isn't the Huawei's K3V2 chip 64bit?

It supposedly has 64-bit registers but is still on the ARMv7 instruction set. Their K3V2 is just a hyped SoC with more registers, that's all.

Mother of God, 3x the performance of the quad S4 Pro and Exynos 5 with the same level of power consumption... Soon phones/tablets will be desktop replacements.

Actually, I think it's 3x the current chips and about 30percent more than A15.
But given that 2ghz A15 seems to be at almost about half the power of 2.66ghz Intel i5, you are pretty much right about the pc replacement

Arguably; they may have the power but there also has to be the software optimization and RAM capabilities at work. Personally I envision a time when a person's entire digital interactions could be accomplished with a phone-size device, much like a smartphone but even more advanced than today's, which interacts wirelessly with peripherals, so a person could take that device to an "internet cafe" and just use the cafe's screen and keyboard and such, keeping all their info on their own phone, then go to the office and do the same.

Exactly..thats how i imagined it turning out years ago.
The only real problems with the idea are ones no tech can solve - losing your phone and using it too much :p

Processors and screens seem to be the areas of mobile devices like smartphones and tablets that are growing the fastest. With the processors becoming so powerful in a short amount of time, I wonder how much screens will improve. I mean come on, the Nexus 10 has 2560 by 1600, and the Droid Incredible DLX (or w/e it's called) has Full HD in 5 inchs. What's next, 4k resolution for a tablet, and 2.5K for a 5 inch phone? I say keep on going lol. Though I think Full HD on a phone is plenty enough, I will love to see if they improve it more :)

Now we need a version of Android with a 64-bit version of the linux kernel 3.x, that shouldn't be difficult at all.

This is great and with Samsung heavily investino in UV, ultraviolet steriolithography, we could see some mind boggling performance in mobile devices soon!

Quad A-15's @ 2.5 Ghz push about 35,000 MIPS, this is Mid range desktop level performance. Certainly no slacker, the A50's probably increases the IPC to almost current high end desktops CPU's MIPS (Millions of Instructions per second).

Where did you get this info from if I may ask ?
