Your Smart Board Has 8GB RAM. So Why Does It Still Lag?
Because RAM is rarely what limits an Android smart board. The processor, graphics chip and storage matter more, and many boards use chips designed for televisions, driving a 4K touch screen while several apps run at once. A board can have 8 GB of RAM and still pair it with four low-power cores and eMMC storage that reads at a fraction of the speed of a modern phone's. Software matters too: the vendor's whiteboard app, the wireless-sharing service, a browser with several tabs and a video call all compete for the same chip. We found no independent benchmark that measures smart-board lag, and we have not tested these units ourselves, so this post compares the specifications vendors publish. At SourceIT, the LG CreateBoard 65TR3DQ (8 GB, Amlogic A311D2 per LG) is S$2,587.50 and the Avocor E50 AVE-6550 is S$3,728.05 (listed 31 Oct 2026).
What is inside popular Android boards?
| Board | Android | Processor (as published) | RAM / storage |
|---|---|---|---|
| Avocor S10E series | 13 | Amlogic T982: four Cortex-A55 cores, Mali-G52 MP2 | 8 GB / 64 GB |
| Avocor E50 series | 13 | Amlogic A311D2: four Cortex-A73 + four A53, Mali-G52 MP8 | 4 GB / 32 GB |
| LG CreateBoard TR3DQ | 14 | Amlogic A311D2 (LG Australia, 55-inch page) | 8 GB / 64 GB eMMC |
| Samsung WAF | 14 | Octa-core, four A73 + four A53 (chip not named) | 8 GB / 64 GB |
| MAXHUB U3 U6530 | 13 | Four Cortex-A76 + four A55, Mali-G610 MP4 (chip not named) | 8 GB / 64 GB |
| MAXHUB U4 U6540 | 15 | Four A76 + four A55 at 2.4 GHz, Mali-G610 MP4 | 16 GB / 256 GB |

Why does the processor matter more than RAM?
- Core type. Cortex-A55 and A53 cores are efficiency cores. The Amlogic T982 has only four A55 cores and, as CNX Software describes it, was designed for 8K televisions. Cortex-A73 cores are older performance cores; A76 cores, found in MAXHUB's U3 and U4 specifications, are newer and stronger. MAXHUB does not name the chip, but its published figures match Rockchip's RK3588.
- Graphics. The screen is 4K. Drawing a smooth ink stroke over a 4K image, or scrolling a large PDF, falls to the graphics chip, and a Mali-G52 MP2 has far fewer graphics cores than a Mali-G610 MP4.
- Storage. LG lists eMMC storage. Samsung's own figures put eMMC 5.1 at 250 MB/s read, against 2,100 MB/s for eUFS 3.1 phone storage. Opening apps, loading lessons and saving whiteboards all wait on storage.
- RAM is still a floor. Avocor's E50 ships with 4 GB. ViewSonic's support article notes that playing 1080p YouTube in the board's browser "uses almost half" of a ViewBoard's working memory, so more RAM does help when several things run at once.
8 GB of RAM is the car park. The processor is the road. A bigger car park does not make traffic move faster.
What makes a board lag in daily use?
- Too many apps left open. A board used all day by different people builds up background apps. ViewSonic tells users to clear running processes and power-cycle when its boards slow down.
- Heavy web content. Video, large web apps and many browser tabs load the chip and memory at the same time.
- Old firmware. Vendors fix performance as well as security in updates, so keep the board current.
- Storage nearly full. Saved files, downloads and cached content pile up on 32 GB or 64 GB of storage. Automatic clean-up, which LG offers on the CreateBoard, helps.
- Wrong job for the board. Running a full desktop workload on a TV-class chip will lag, however much RAM it has. That is what a Windows OPS module is for.
What should you check before buying?
- Ask for the processor name, not just "octa-core". Core counts say nothing about core type: four A55 cores and four A76 cores perform very differently.
- Ask for storage type and size. For a shared board, 64 GB or more leaves room for saved files and firmware updates.
- Try the board with your own content: your lesson slides, your dashboards, your video call.
- Consider an upgradable compute slot. Avocor lists its EDLA Android OPS module, with an RK3588-class processor and 8 GB, as the Android option for its H, E50, E92, S and B series, and Windows OPS modules add a full PC.
- Check the Android version as well as the speed. Android 13 is no longer on Google's security bulletin; see Your Android Smart Board Could Become Obsolete Before the Screen Dies.
If the Windows side of a board is the one that feels slow, the causes are different. See Why Some Windows Smart Boards Feel Slower Than Android Displays.

Frequently asked questions
Why does my interactive display lag with 8 GB of RAM? The processor, graphics chip and storage usually limit performance more than RAM. Many boards use TV-class chips and eMMC storage driving a 4K screen.
What processor do Android smart boards use? Published examples include Amlogic's T982 and A311D2. MAXHUB's U3 and U4 specifications match Rockchip's RK3588, although MAXHUB does not name the chip.
Is eMMC storage slow? Compared with phone or PC storage, yes. Samsung's figures put eMMC 5.1 at 250 MB/s read, against 2,100 MB/s for eUFS 3.1.
How can I make a laggy smart board faster? Close background apps, restart the board regularly, keep firmware updated, free up storage, and move heavy desktop work to a Windows OPS module.
Does more RAM help an interactive display? It helps when several apps or browser tabs run at once, but it does not make a slow processor faster.
