Hardware Overview and CPU Performance

The Umi Impact features a non-too-surprising assortment of hardware at its price point. The center of it all is a MediaTek MT6753 SoC, which is a standard octa-core design with eight ARM Cortex-A53 CPU cores clocked at up to i.5 GHz. This chip is congenital using an aging 28nm process and supports 64-fleck instructions thank you to ARMv8-A.

Inside the MT6753 in that location'due south a Mali-T720 MP3 GPU clocked at 700 MHz, which is an entry-level configuration. This device comes with 3 GB of LPDDR3 retention and 16 GB of internal NAND plus a microSD card slot.

Wireless support is average across the board. There's Wi-Fi 802.11a/b/g/n on both the 2.4 GHz and five GHz bands, just no 802.11ac. Bluetooth 4.one and GPS are congenital-in also, and the lack of NFC isn't surprising at this price point. You should be very wary of HSPA and LTE support, though: Umi lists back up for but two HSPA bands (900 and 2100 MHz) also equally three LTE bands (3, 7 and xx). This covers a limited array of networks worldwide (mostly Europe and Asia), and massively neglects North America in particular.

The Umi Bear upon's full general performance is, quite frankly, non bang-up, even for an entry-level device. I ofttimes experienced slowdowns and stutters performing basic tasks, and the occasional sluggish animation makes this far from a smooth Android experience. When cheaper devices the Moto E experience faster and smoother to use than the Umi Touch, that'southward a serious choice and speaks volumes about the lack of optimization.

Not everything most the performance is bad. App loading speed is acceptable for a budget handset, and iii GB of RAM does help to avoid complete app reloads when multi-tasking (to an extent). Functioning has also improved significantly thanks to a few recent updates, turning what I'd call 'horrendous' operation with frequent stutters and slowdowns into 'below boilerplate' class functioning.

Raw performance in CPU-limited benchmarks indicates the Snapdragon 410, establish in budget devices similar the $eighty Moto E 2015 and $160 Moto G 2015, is just three percent slower than the MediaTek MT6753 in the Umi Touch. This is a huge win for Qualcomm's silicon, as the Snapdragon 410 has a hardware disadvantage with four A53 cores clocked at up to one.2 GHz, compared to eight cores at 1.v GHz in the MT6753.

This sort of scenario is adequately typical for MediaTek hardware. On newspaper, you'd recollect the MT6753 should outperform the Snapdragon 410 by at least 25% considering that is the departure in CPU clock speeds, but this is rarely the case. Instead, perhaps due to poor drivers from MediaTek or a lack of optimization, the MT6753 merely has a slight CPU functioning advantage. This is one of the reasons why I don't rate MediaTek as highly equally I do Qualcomm or Samsung, and why y'all simply tin't await at the spec canvas and await a sure level of performance.
