I just want Plan 9front or 9legacy and the Go programming language running on it.
- easygenes 5y agoCortex-A53, also of that 5-years-old Cortex-A73 generation. The A5x are the lower-powered variants of the A7*, so these sit below a RasPi 4. The neat bit of this board is the NPU, but it's only 4 TOPS. There's a lot of showing of those "A[5,7][2,3]" chips in the sub-$150 range. What I want is A77+ performance, also with a capable GPU, VPU, and NPU. It should sit more in the $250-400 range.
- easygenes 5y agoOh, the nice thing about those i.MX8M based boards, similar to RK3399 ones on the higher end, is that their GPU/VPU has been pretty fully reverse-engineered and kernel mainlined now. That was the biggest announcement for the release of the RasPi OS Bullseye update just the other week: using kernel KMS for graphics by default. I just want that same level of support for something a few years newer and a good deal faster.
- easygenes 5y agoOh, if you haven't seen it, check out the Khadas VIM3 [1][2]. It's pretty comparable performance to Jetson Nano. [3] It is a bit more capable than the Coral board and is a favorite of the Armbian team. Cheaper and better availability too. It still suffers from the trappings of running on the Cortex-A73 generation though. E.g., it has PCI-e/NVMe support and USB3 support, but you have to decide which one is usable because it doesn't have enough PCI-e lanes. 1: https://www.khadas.com/vim3 2: https://browser.geekbench.com/v5/cpu/9975526 3: https://browser.geekbench.com/v5/cpu/9193154
