Archos launches a pair of Android smartphones, including one model powered by the MT-6592
The Archos Oxygen 50b offers the same 5 inch screen, but with some changes. Under the hood is a quad-core 1.3GHz MediaTek MT-6582 processor. 1GB of RAM is inside with 4GB or 8GB of native storage, depending on the model. The same 64GB capacity microSD slot seen on the 50c Oxygen is available on this model as well, along with the same 2000mAh battery. Android 4.2.2 is also pre-installed.
In case you make your phone purchasing decisions based on the thickness of the handset, the Archos 50c Oxygen is a fairly svelte 7.64mm thin while the 50b Oxygen is nearly a silly millimeter thicker at 8.6mm. Both models are available today, with the Archos 50c Oxygen priced at £179 ($304 USD) and the Archos 50b Oxygen tagged at £129 ($219 USD).
