Samsung Galaxy S3 has been in the market for almost two years now and it is still a good option as an Android 4.4 KitKat update is on its way. The smartphone is also very economical and has millions of users around the world. The worldwide popularity of this smartphone would definitely make it comparative with the recently unveiled Samsung Galaxy S5 in the weeks ahead.

The new Samsung S5 is unlikely to be available in the market until April 2014, so we bring to you some of the key differences between the Samsung Galaxy S3 and the brand new Samsung Galaxy S5 in order to update you on the key offerings.

The Samsung Galaxy S3 has polycarbonate plastic and sleek curves, a microSD card slot and a removable battery. On the other hand, the Samsung Galaxy S5 would also have a removable back plate and a microSD card slot but its body would be made of metal not plastic. The new Galaxy S5 would have a dust and water resistant design.

The thickness of the Galaxy S5 would be 8.1mm, which is much less than the 8.6mm thickness of the Galaxy S3. The Galaxy S5 would have a weight of 145 grams, but the weight of the Galaxy S3 is only 133 grams.

Samsung Galaxy S3 is available in a 4.8-inch screen size with a pixel resolution of 720 x 1280, while Galaxy S5 would boast a 5.1 inch full HD screen having a pixel resolution of 1080 x 1920.

The Galaxy S3 has 8MP camera, while the Galaxy S5 will be equipped with a 16MP camera featuring hybrid autofocus system and advanced high dynamic range.

The Samsung Galaxy S3 features a standard home button, while the Galaxy S5 does not have this feature and is installed with a finger reader.

Samsung Galaxy S3 is powered by an aging Snapdragon S4 Plus dual-core chip processor, while the new smartphone is likely to run on Qualcomm’s new Snapdragon 801 quad-core processor and an octo-core Exynos processor. The upgraded processor would offer its users a convenience of multitasking and better gaming experience than the Galaxy S3.
