I've worked with STB hardware before and they usually suck. The processors that I worked with were all from MIPS and it felt like all useful instructions were removed, except for the bare basics. Forget anything related to vectorization, for example. They were painfully slow.
- kasabali 4y agoThese boxes generally utilize stock Cortex A53/A55 which are quite good IMO.
- avidiax 4y ago"Good" as in they can do anything slowly. A7x boxes won't struggle.
- Matsta 4y agoExactly. A53 cores are efficiency cores designed for non-intensive background tasks in phones to save battery. The only decent cpu atm that will eventually show up in TV boxes is the Rockchip Rk3588, but they aren't as cheap as some old s905x chips, and software support is very early days, so it will be a while before we see them in any android tv boxes. The key does seem to be you need at least a quad-core of high-efficiency cores. The Nvidia Tegra X1 found in the Nvidia Shield and Switch runs fine even though it has even older A57 cores(predecessor to the A72). Compare this to rockchip's last-gen Rk3399, which only has 2x A72 cores (and 4x A53 cores) and is pretty slow compared to a Rpi 4 (but that could also be because of crap software support on the Rockchip side)
- kasabali 4y agoGood as in they implement the ARMv8 architecture fully unlike the crippled cores parent comment was talking about, also being more powerful because they're still 4-cores, GHz CPUs while the MIPS parent was talking about probably only had 1-2 core(s) and low 3-digit MHz clock speed.
