Hardware Overview and CPU Performance

The Umi Impact features a not-too-surprising array of hardware at its cost point. The center of it all is a MediaTek MT6753 SoC, which is a standard octa-core blueprint with 8 ARM Cortex-A53 CPU cores clocked at up to ane.five GHz. This chip is built using an crumbling 28nm process and supports 64-bit instructions thanks to ARMv8-A.

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

Wireless support is average across the board. There'southward Wi-Fi 802.11a/b/g/due north on both the 2.4 GHz and 5 GHz bands, but no 802.11ac. Bluetooth 4.ane and GPS are congenital-in every bit well, and the lack of NFC isn't surprising at this cost point. You should be very wary of HSPA and LTE support, though: Umi lists support for just two HSPA bands (900 and 2100 MHz) as well equally three LTE bands (three, seven and twenty). This covers a limited array of networks worldwide (mostly Europe and Asia), and massively neglects North America in particular.

The Umi Touch'south general performance is, quite bluntly, not great, even for an entry-level device. I often experienced slowdowns and stutters performing bones tasks, and the occasional sluggish animation makes this far from a shine Android experience. When cheaper devices the Moto E feel faster and smoother to use than the Umi Affect, that's a serious option and speaks volumes nearly the lack of optimization.

Non everything virtually the functioning is bad. App loading speed is acceptable for a budget handset, and 3 GB of RAM does help to avoid complete app reloads when multi-tasking (to an extent). Operation has as well improved significantly thanks to a few recent updates, turning what I'd call 'horrendous' functioning with frequent stutters and slowdowns into 'below average' class performance.

Raw performance in CPU-limited benchmarks indicates the Snapdragon 410, establish in upkeep devices like the $80 Moto Eastward 2022 and $160 Moto G 2022, is merely iii percent slower than the MediaTek MT6753 in the Umi Bear on. This is a huge win for Qualcomm'southward silicon, every bit the Snapdragon 410 has a hardware disadvantage with four A53 cores clocked at up to 1.2 GHz, compared to 8 cores at 1.5 GHz in the MT6753.

This sort of scenario is fairly typical for MediaTek hardware. On newspaper, yous'd remember the MT6753 should outperform the Snapdragon 410 by at least 25% considering that is the difference in CPU clock speeds, but this is rarely the example. Instead, perhaps due to poor drivers from MediaTek or a lack of optimization, the MT6753 only has a slight CPU performance advantage. This is one of the reasons why I don't rate MediaTek every bit highly as I exercise Qualcomm or Samsung, and why you simply tin can't look at the spec canvas and expect a certain level of performance.
