The LTE version's Snapdragon 800 contains the Adreno 330 GPU, which improves performance of its Adreno 320 predecessor by about 50 percent, according to Qualcomm documentation. Samsung's Exynos 5 returns to the ARM-based GPU. In this case, it's the Mali-T628 MP6, which is designed to incorporate from one to eight cores. Qualcomm says it delivers up to 10 times the performance of the Mali-400, the GPU found in several earlier Galaxy device models. Apple's A7 reportedly includes the dual-core PowerVR G6430 four-cluster GPU by Imagination Technologies, which claims up to 20-times performance boost over prior generations.
Either Samsung device packs three GB of LPDDR3 RAM and comes with either 32 GB or 64 GB of storage; a microSD card slot can add as much as 64 GB more. The iPad Air is built with 1 GB of RAM and comes in models with 16-, 32-, 64- and 128-GB storage.
