If you’re mainly using your Android mini PC or STB to stream videos over the web or your local network, Wi-Fi performance is actually more important than CPU performance, and I’ve recently had quite a few issues with Wi-Fi with both T428 (RK3188 / Broadcom Wi-Fi module) and CS868 (AllWinner A31 / Realtek Wi-Fi module), which were only fixed after upgrading my router firmware. So I’ve decided to re-test most of the mini PCs I own with the upgraded router firmware, and the number are highly confusing, and I found out there’s probably be no easy to way to estimate the overall Wi-Fi performance of any device, and it’s most probably highly dependent on the router used, and its firmware version. My router is TP-LINK WR940N, a 300 Mbps Wireless N router with three antennas. Since I bought it, I had never upgraded the firmware (3.9.18 Build 100104 Rel.36350n) from […]
I’m always very confused when it comes to comparing GPUs in different SoCs, and I could not really find comparisons on the web, so I’m going to give it a try even though, as you’re going to find out, it’s actually quite a challenge. There are mainly 4 companies that provide GPUs: ARM, Imagination Technologies, Vivante and Nvidia. [Update: Two comments mentioned Qualcomm Adreno and Broadcom VideoCore are missing from the list. Maybe I’ll do an update later]. Each company offers many different versions and flavors of their GPU as summarized below. ARM Imagination Technologies Vivante Nvidia Mali-400 Series: Mali-400 MP Mali-450 MP Mali-600 Series Mali-T604 Mali-T624 Mali-T628 Mali-T658 Mali-T678 PowerVR SGX Series 5: SGX520 SGX530 SGX531 SGX535 SGX540 SGX545 PowerVR SGX Series 5XT: SGX543MP1-16 SGX544MP1-16 SGX554MP1-16 PowerVR SGX Series 6: G6200 G6230 G6400 G6430 G6600 2D graphics: GC300 GC350 3D graphics: GC400 GC800 GC1000 GC2000 GC4000 ULP GeForce (Tegra […]
This list of Android/Linux development board lists does not intend to be exhaustive. On the contrary, I only plan to list the boards that I find remarkable either by the level of community support, price or features, and I plan to keep the list shorter than 10 boards/vendors. I’ll also focus on the cheaper boards (less than $100, or slightly above) as those sell in larger quantities than more expensive boards. If you are interested in the latter, I have a list of the top 5 most powerful Arm boards (in 2017/early 2018). Raspberry Pi Boards The Raspberry Pi Foundation has sold close to 20 millions boards as of Q2 2018, and the Raspberry Pi boards are a step above the competition in terms of sales thanks to the relatively low cost and excellent software support of the platform. There are several models, but the two most popular right now […]
