No matter whether you're deciding if you should wait and get the Samsung Galaxy S4 next week, making sure you don't have buyer's remorse from just having purchased your Galaxy S3, or perhaps just plain curious, CNET makes it easy to compare the two sibling handsets with this chart.
Physically, the GS4 didn't get any bigger. In fact, it even sports a thinner build and weighs a hair lighter. But with a slimmer bezel, its 5-inch full HD Super AMOLED touch screen had room to expand, and the display now sports a higher pixel density.
Also new is its quad- or octo-core processor. Similar to the situation when the GS3 debuted, which CPU is available will depend on where you live. The U.S. will receive the 1.9GHz quad-core Snapdragon 600.
Both cameras also got a bump, with the rear shooter jumping from 8 megapixels to 13 megapixels. Other changes include running the newer Android 4.2.2 Jelly Bean, a beefed-up battery, and a slew of new software features. And if you want to see how the GS4 compares with other flagship handsets, be sure to read our other chart.
