Which smartphone/tablet owns the fastest processor?

Sorry, the Nexus 7 didn't qualify in the Top 3, as it "only" has a quad-core 1.3 GHz CPU.

The S4 used on the One X usually out preforms the GS3 and other phones using it, but I still would say the GS3 is better than the ONEX

It might very well be, but those things are hard to measure, so in this competition here we're just looking at the number of cores and clock rates of the processors.

The T3 smoked the A5X in most benchmarks. Besides, I'd rather play on a tablet with a widescreen display than a boxier tablet. The iPad isn't bad though for iOS fans, I'll give you that. I've played with my friend's iPad 2. It's pretty nice. :)

The Infinity also has the same architecture

This venerable athlete was once on top of its game, but has been retired for quite some time now.

"Sandy Bridge". Goddamned incorrect.

To tedkord you listen. Know what he's talking about, he does.

thanks for saving me some finger stress. Seriously... WHAT? I'm sorry Ray, but you need to do a lot of research on chips before doing such a baseless comparison. The exynos found in the SGS3 blows the snot out of the T3 chip at equal frequencies, lower frequencies, and even higher frequencies. Under your assumptions backed up by no facts, a (if there was such a thing) quad core Pentium4 chip running at 3ghz would blow away a core2duo running at 2ghz. Which is simply not true. There are so many factors to take into consideration its not funny.. which is why we lean so heavily on benchmarks. And the benchmarks show quite the opposite. the exynos 4412 obliterates the T3 in all shapes and forms. The ONLY chip that has posted a higher bench than the 4412 is the unreleased S4 "Pro" chip which barely aced it out because of its new GPU. Of course that will be tossed by the exynos 5250, but that is a different story for a different day.

I can see what your talking about tedkord. But you're forgetting that were talking about ARM CPUs here. You can't compare desktop CPUs to Mobile CPUs because so many variables differ, and so many inconsistencies arise. Remember, each CPU, first and foremost is constructed by ARM, and then tweaked to what ever liking the OEM desires. Different mobile factors like Cortexes put a sort of theoretical speed limit on how fast a CPU can be on that given cortex. Things like cache, DMIPS, Floating points, FSB speed, RAM speed and channels and pipelines only increase performance by the amount that a Cortex could yield. CPUs can only be that much faster than the other when they are burdened by the same theoretical speed limits. Even something like manufacturing process do not yield as many improvements on a Mobile CPU as opposed to a desktop CPU, because of transistor leakage. There are so many variables that decide the speed of a desktop CPU that simply aren't present, or do not make much a difference on a mobile CPU. Ivy, Sandy and Bulldozer are seperated by so many different manufacturing specifics, it is easy to see why the latter CPU, well, sucks. Also factor in given motherboards, VRMs and all that. But CPUs like Exynos 4412 and Tegra 3(infinity) are based off the same Cortex(although Exynos' Bus width was increased from 64 to 128, mirroring Cortex A-15), and can only differ from each other speed-wise(excluding GPU) in so many ways. ARM is the key here, they have the hand in virtually all the CPUs, so they can set that theoretical speed limit. Any slight deviation from ARM's "rule book" can cause significant defects in performance because we are also dealing with many physical space confinements, although that is not the only reason why. We can talk about batteries, and how Desktop CPUs are given ample amounts of power and circuitry to complete their calculations, but that would only bloat things. Only when we move to Cortex A-15 can we see the theoretical speed limit increase, and see Dual-Cores outclass Quad-Cores of the previous Cortex.
