Samsung Galaxy S3 vs Apple iPhone 5: Screen
The Galaxy S3 has a 4.8-inch display and while every single iPhone in the past has had a comparatively tiny 3.5-inch one, the iPhone 5 has a 4in display.
Apple has increased the screen size and also the resolution to 640 x 1136, retaining the Retina quality pixel density of 326ppi. Samsung's Galaxy S3 has a slightly lower but respectable pixel density of 306ppi from its 720 x 1280 resolution.
Samsung Galaxy S3 vs Apple iPhone 5: Processor
Samsung uses its own Exynos 4 Quad chip for the Galaxy S3 which is unsurprisingly quad-core. It's clocked at 1.4GHz and is based on the ARM Cortex A9 architecture.
As expected the iPhone 5 has an A6 processor which Apple says is twice as fast as the A5 chip found in the iPhone 4S, including graphics performance. Apple hasn't revealed any technical specifications for the A6 so it's hard to compare with the Galaxy S3's. It is believed that the A6 is dual-core.

Both the Galaxy S3 and the iPhone 5 come with three storage options, 16GB, 32GB and 64GB. Samsung does, however, include a microSD card slot for expansion (up to a further 64GB) which Apple does not.

The Galaxy S3 has a rear facing camera rated at 8Mp with the ability to record video in full HD 1080p quality which Apple matches with the iPhone 5's rear iSight camera, although each has different software features.
Both front cameras on the smartphones can record HD video at 30fps but the Galaxy S3's has a slightly higher rating at 1.9Mp compared to 1.2Mp.
