Samsung Galaxy Tab A11

  • Superior performance thanks to the Mediatek Helio G99 chipset.
  • Exceptional battery life (93:40h endurance).
  • More efficient 6nm fabrication process reduces heat and improves longevity.

  • Detailed display specifications are unknown.
  • Camera performance is likely basic, similar to the A8.

Samsung Galaxy Tab A8 10.5 (2021)

  • Established platform with a wider user base.
  • Adequate performance for basic tasks like web browsing and video streaming.
  • Generally lower price point (depending on retailer).

  • Less powerful Unisoc Tiger T618 chipset.
  • Significantly shorter battery life compared to the A11.
  • 12nm fabrication process is less efficient.

Display Comparison

Both tablets are expected to feature 10.5-inch LCD panels, typical for this price segment. However, detailed display specs like resolution, brightness, and color gamut are not provided. Given the A8’s 2021 release, it may benefit from slightly more refined color calibration, but the A11’s newer chipset could potentially support more advanced display features in future software updates. Bezels are likely comparable, reflecting the budget nature of both devices.

Camera Comparison

Neither tablet is positioned as a photography powerhouse. Detailed camera specifications are unavailable, but it’s safe to assume both feature basic rear and front-facing cameras suitable for video calls and casual snapshots. Without sensor size or aperture information, a direct comparison is difficult. However, the A11’s more powerful ISP (Image Signal Processor) within the Helio G99 chipset *could* result in slightly better image processing, particularly in low-light conditions, but this is speculative.

Performance

The core difference lies in the chipsets. The Tab A11’s Mediatek Helio G99 (6nm) boasts a more modern architecture – specifically, Cortex-A76 cores alongside A55s – compared to the A8’s Unisoc Tiger T618 (12nm) which uses Cortex-A75 cores. The 6nm fabrication process of the Helio G99 translates to significantly improved power efficiency and thermal performance. This means the A11 can sustain higher performance for longer periods without throttling. While both are octa-core CPUs with a similar core configuration (2x high-performance, 6x efficiency), the architectural improvements in the G99 give it a clear edge in CPU-intensive tasks. The A11 is expected to show a noticeable improvement in app loading times and overall responsiveness.

Battery Life

The Tab A11 truly shines in battery endurance, achieving a remarkable 93:40 hours in testing, coupled with a rated 1200 charge cycles. This is a substantial improvement over what’s typically seen in this price range. While both tablets support 15W wired charging, the Helio G99’s superior power efficiency means the A11 will likely reach a full charge faster and maintain its charge for a longer duration. The A8, while offering adequate battery life for typical use, simply can’t compete with the A11’s longevity.

Buying Guide

Buy the Samsung Galaxy Tab A11 if you prioritize performance for multitasking, light gaming, and future-proofing. Its newer chipset and longer battery life make it ideal for users who demand more from their tablet. Buy the Samsung Galaxy Tab A8 10.5 (2021) if you prefer a slightly more established platform and are primarily focused on basic tasks like video streaming and web browsing, and are less concerned with demanding applications.

Frequently Asked Questions

❓ Will the Mediatek Helio G99 in the Tab A11 handle demanding games like PUBG or Call of Duty Mobile?
While the Helio G99 isn't a flagship gaming chip, it's significantly more capable than the Unisoc T618. You should be able to play PUBG and Call of Duty Mobile at medium settings with reasonable frame rates. However, don't expect the same experience as a dedicated gaming tablet.
❓ How does the 15W charging compare between the Tab A11 and A8, given the different chipsets?
Although both tablets support 15W charging, the Tab A11’s Helio G99 is more power-efficient. This means it will likely reach a full charge faster and consume less energy during the charging process, contributing to its overall longer battery life.
❓ Is the Unisoc Tiger T618 in the Tab A8 sufficient for everyday tasks like browsing and streaming?
Yes, the Unisoc Tiger T618 is perfectly adequate for everyday tasks like web browsing, video streaming, and social media. However, it will struggle with more demanding applications or heavy multitasking compared to the Tab A11.
❓ What is the expected software update support for both tablets?
Samsung typically provides two major Android updates and several years of security patches for its tablets. However, given the A8’s 2021 release, it may receive one fewer major update than the A11. Long-term software support is an area where Samsung generally performs well, but it's not guaranteed for budget tablets.
