Display Comparison
Display specifications are absent for the Acer Iconia One 8 B1-820, but given its age and market positioning, it likely features a TN panel with limited viewing angles and color accuracy. The Doogee Tab E3's display details are also missing, but the focus here is performance. The older Intel Atom processor will struggle to drive a high-resolution, high-refresh-rate display effectively, making the display quality less of a bottleneck on the Acer. The Doogee's more powerful GPU will allow for smoother rendering of content, regardless of the panel's inherent limitations.
Camera Comparison
Camera details are not provided for either device. Given the budget nature of both tablets, it's safe to assume that camera quality is not a primary focus. Expect basic sensors suitable for casual snapshots, but not for serious photography. The Doogee Tab E3's more powerful ISP (Image Signal Processor), integrated within the Helio G100 chipset, *may* offer slightly better image processing, but this is speculative without further information.
Performance
The performance gap is the defining characteristic of this comparison. The Doogee Tab E3's Mediatek Helio G100, built on a 6nm process, features an octa-core configuration (2x2.2 GHz Cortex-A76 & 6x2.0 GHz Cortex-A55). This is a *massive* upgrade over the Acer Iconia One 8 B1-820's quad-core 1.33 GHz Intel Atom Z3735G. The Cortex-A76 cores in the Helio G100 offer significantly higher single-core performance, crucial for responsive app launches and UI navigation. The 6nm process also translates to improved power efficiency and reduced thermal throttling. The Acer's Atom processor, while adequate for its time, is simply outmatched in every metric.
Battery Life
The Doogee Tab E3 boasts an impressive 93:08h endurance rating, suggesting a large battery capacity and efficient power management. The 18W wired charging is a welcome addition, allowing for relatively quick top-ups. The 2.5W reverse wired charging is a niche feature, useful for charging small accessories like earbuds. The Acer Iconia One 8 B1-820's battery capacity and charging speed are unknown, but given its older chipset and likely smaller battery, it will almost certainly fall short of the Doogee Tab E3 in both endurance and charging speed.
Buying Guide
Buy the Doogee Tab E3 if you need a tablet capable of handling modern apps, streaming video smoothly, and offering a responsive user experience. Its 93:08h battery endurance and reverse charging capabilities add further value. Buy the Acer Iconia One 8 B1-820 if you prioritize extreme affordability above all else and only require basic functionality like web browsing and light document editing. Be prepared for noticeable slowdowns with anything beyond the simplest tasks.
Frequently Asked Questions
❓ Will the Doogee Tab E3 handle demanding games like PUBG or Call of Duty Mobile?
The Mediatek Helio G100 chipset in the Doogee Tab E3 is capable of running many popular games, including PUBG and Call of Duty Mobile. However, performance will depend on the game's settings. Expect to play at medium settings for a smooth experience. The Acer Iconia One 8 B1-820 would struggle significantly with these titles.
❓ Is the reverse charging feature on the Doogee Tab E3 useful for anything beyond earbuds?
While 2.5W reverse charging is slow, it can provide a trickle charge to smartphones or other small devices in a pinch. It's not a replacement for a dedicated power bank, but it can be a lifesaver if you're caught without a charger and need a small boost for your earbuds or smartwatch.
❓ How much of a performance difference can I realistically expect between the Helio G100 and the Intel Atom Z3735G?
The difference is substantial. The Helio G100 is a modern, octa-core processor built on a 6nm process, while the Intel Atom Z3735G is an older, quad-core processor. In real-world usage, this translates to significantly faster app launches, smoother multitasking, and a more responsive user experience on the Doogee Tab E3. The Acer Iconia One 8 B1-820 will exhibit noticeable lag and slowdowns with even moderate use.
