Engine Room
1st: Galaxy S3 : Samsung Exynos 4212 chipset, 1.4GHz Quad-core CPU
2nd: Galaxy Nexus : dual-core 1.2GHz Cortex-A9 CPU and a PowerVR SGX540 GPU
The Galaxy Nexus runs on a Ti-OMAP 4460 chipset, consisting of a dual-core 1.2GHz Cortex-A9 CPU and a PowerVR SGX540 GPU, which should cope with everything you can throw at it, even if it is a little on the old side. The Galaxy Nexus comes with 1GB RAM installed, making multi-tasking, switching between apps and general use very spry indeed.
Samsung uses its own Processor Exynos 4 Cortex A9 quad-core chips aided by a fresh GPU that is supposedly 65 percent faster than the companion Mali 400 graphics chip on the Galaxy S II.
Samsung believes that kind of horsepower is necessary to drive a 4.8-inch HD Super AMOLED display with 1,280 x 720 resolutions, among other things. Early benchmarks show that the Exynos 4212 is also significantly faster than the Tegra 3 - this time across the board rather than just in graphical performance.
Samsung Galaxy S III (European variant) with Exynos 4 Quad highlights, according to Samsung:
Speed jump: Owing to its 32-nanometer tech, the Exynos 4 Quad has "two times the processing capability over the 45-[nanometer] process based Exynos dual-core while consuming 20-percent less power."
Exynos 4 Quad is "pin-to-pin compatible" with the Exynos 4 Dual, allowing smartphone and tablet suppliers to adopt the new solution without additional engineering or design efforts (Ready to plug into new phones).
The chip is based on the current Cortex A9 tech from ARM. The latest and greatest ARM tech is called Cortex A15 but those chips won't emerge as commercial products for a while yet.

Storage
1st: Galaxy S3 : 16/32/64 GB plus MicroSD cards
2nd: Galaxy Nexus : 16/32GB
Galaxy S3 comes with three storage capacities 16GB, 32GB, and 64GB while Nexus comes with only two, and Galaxy S3 has a microSD card slot for up to another 64GB of storage.
It was rumoured that Samsung was going to launch SCloud but the S3 will come with a free two-year 50GB Dropbox account.
Camera
1st: Galaxy S3 : 8MP rear, 1.9MP front camera autofocus, LED flash
2nd: Galaxy Nexus : 5MP rear , 1.3MP front Camera autofocus, LED flash
Both phones have 8-megapixel primary cameras, 1080p video and video calling capability.
The Galaxy S3 sports a "select your best shot" feature after taking multiple shots. The handset will automatically suggest the best image for you based on a few factors including smile detection and facial recognition.
Now you can also take a picture while recording a video. Other features include contact tagging and automatic photo grouping based on who is in the picture. There is a 1.9-megapixel front-facing camera also has face detection, which keeps the screen awake and from dimming if you are looking at it.
The Galaxy Nexus have only 5-megapixel camera, but a few software tweaks allow the snapper to work surprisingly well. The camera features autofocus, LED flash, touch-focus, geo-tagging and face detection, as well as 1080P video capture and also, according to Google, has no shutter lag, so what you see is what you snap. The font camera is 1.3-megapixel secondary camera.


The Design
1st: Samsung Galaxy S3 - 136 x 70.6x 8.6mm, 133g
2nd: Samsung Galaxy Nexus - 135.5 x 67.9 x 8.9 mm, 135g
Galaxy Nexus is thin and nicely designed and built device though, and the rounded off edges and newly designed back-plate offer a solid hand-hold, which is most welcome as it isn't the narrowest smartphone on the market.
As with the rest of the Galaxy range it's crafted almost entirely from plastics, which is a point that is likely to split opinion. Some like it lightweight, others like to be able to feel some of their hard earned pounds and pence when they handle their device.
The galaxy S3 is larger and lighter than iPhone 4S and is slimmer than iPhone 4S. Even though the Galaxy S3 is bigger but it is comfortable to hold. Both handset has Gorilla Glass, but Galaxy S3 has a plastic build. Using plastic as the main body material pays off in weight.
Galaxy S3 shape is inspired by nature it sees, listens, responds, and allows you to share the greatest moments'. Samsung also has reduced the bezel size keeping the dimensions down as much as possible. Samsung's Galaxy S3 comes in two shiny plastic finishes - white and a dark blue brushed metal-effect, but it's still a plastic.

Samsung kept it traditional as the handset has a physical home button unlike Galaxy Nexus, touch-sensitive keys and the plastic feel and fragile removable rear cover ( gives you access to change battery or memory card via microSD) does not give a good grip like Galaxy Nexus.
Software
1st: Galaxy S3 : Android Ice Cream Sandwich,TouchWiz UI, S Voice
2nd: Galaxy Nexus : Android Ice Cream Sandwich
Both phone will be runing Android 4.0, otherwise known as Ice Cream Sandwich, and this iteration of the OS is a huge leap forward in terms of design, features and maturity.
In addition Ice Cream Sandwich's selling points is that the UI is set in stone, meaning what Google says, goes. No more will you have to wait for your manufacturer to get its grubby mitts on the software and add eye-candy to it before rolling it out to you.
In Galaxy S3 Samsung has added more tweaks to its TouchWiz UI. The software features include a new "Pop up Play" video function which lets you watch a video while doing other things such as surfing the Web or sending text messages. Android Beam (an NFC-based feature) has also been beefed up, now is called S Beam (You can use this to beam stuff to other phones . It uses Wi-Fi and NFC. If your friend has their Wi-Fi off, it temporarily turns their Wi-Fi on for the transfer, then turns it off and will also let you transfer large files using Wi-Fi Direct (for speeds of up to 300Mbps).

The handset has the same voice control feature found on the Galaxy Note, called S Voice (like Siri You can say to take a picture (say “Cheese!” to make it take a picture). You can configure these commands) and you can even use it to wake up your handset. Samsung has also made it part of the Ice Cream Sandwich Face Unlock feature; it now needs to see your face and hear your voice before you can unlock the handset.
Other features includes Smart Stay (Uses the front facing camera to determine if you’re looking at the phone. You can then set intervals from as little as 15 seconds, which result in a flashing eyeball in your notification bar. If it notices your eyes wander, it will dim the screen), Direct Call (Auto-dials the contact if you have their contact details or messages opens. Move the phone, the sensors kick in and the proximity sensor starts up. If your face is next to the speaker, it will dial that contact) and Smart Alert (One of the neater features, it will vibrate and flash the LED when you pick it up in your hand to say that you’ve missed a call).

AllShare Play, which is another was to share content on virus devices. This feature lets you work together through the magic of DLNA and Wi-Fi Direct, giving us remote access to documents and multimedia files when we work on a different screen somewhere else.
Display
1st: Galaxy S3 : 4.8-inch, 1280x720p, Super AMOLED HD display, 306ppi
2nd: Galaxy Nexus : 4.65-inch Super AMOLED display, 316ppi
The Galaxy Nexus features a 4.65-inch Super AMOLED display that operates at a resolution of 720 x 1280 and boasts a pixel density of 316PPI, which is as close to 'Retina Display' standard as you're going to get without buying an Apple device.
Galaxy S3 screen is gorgeous, everything appears sharp, fonts were crisp, and colours were vibrant. The Samsung Galaxy S3's Super AMOLED screen avoids this effect.
