Does anyone know any board that is similar to RPi 4, with 8GB of RAM or more and a SATA port or an nvme slot? ARM would be great.

- othercharles 6y agoGenerally speaking you can choose either power efficiency or a wide bus, but rarely both. If you want a crappy underpowered m.2 slot, probably Intel Atom is the cheapest route. High performance ARM with m.2 PCI, not sure, but guessing if it's around it probably isn't cheap
- lifty 6y agoYeah, that makes sense. I wouldn't expect the same price point as an RPi and would love a higher performance CPU, but I think they are not out there at the moment. Wouldn't mind having something like 8 graviton2 cores and an nvme slot :)
- throwaway894345 6y agoLet's say one has a friend who doesn't know what "a wide bus" refers to... What would be a good way of explaining it to said friend?
- othercharles 6y agoA single PCIe lane can draw 0.5 A, 4x rises to 2 A. Separately, (random top Google result cutpaste): Architectural-level power optimization can target different system components such as CPU, caches, main memory,and buses [5, 6, 22, 4]. Power spent in off-chip buses can be a significant portion of the overall power budget. As an example, the core power consumption of Intel Celeron at 266MHz is 16W, while its off-chip bus (for a standard configuration) operating at 133 MHz consumes 3.3W [12, 13]. The contribution of off-chip bus power consumption to the overall power budget increases even more for embedded systems with low-power processor cores and memories, making off-chip buses a potential candidate for power optimization. Figure 1 shows the power consumption due to off-chip data bus for several embedded benchmark codes as a percentage of the overall power consumption (which includes processor data path, caches, buses, TLB, register file, instruction issue logic, clock, and off-chip memory) for an embedded processor. From this figure, we see that the off-chip data bus consumes between 9.8% and 23.2% of the total power consumed by the system depending on the benchmark being run. So, reducing the power consumption of the off-chip data bus would reduce the overall power consumption of the system to a considerable extent

- m-p-3 6y agoMaybe there's something out there, but I don't know of any other SBCs than the Pi4 having more or equal to 8GB. If you can settle for 4GB, there's tye Rock Pi 4 which has a variant with on-board eMMC or an m.2 slot.
- tuatoru 6y agoAlso Friendlyarm's NanoPC T4. M.2 PCIe x4, 4GB LPDDR3 (a bit old perhaps). https://www.friendlyarm.com/index.php?route=product/product&path=69&product_id=225 https://www.friendlyarm.com/index.php?route=product/product&...
- shorts_theory 6y agoConsiderably more powerful and expensive, but the Jetson TX2 or Xavier NX fits this niche quite well.
- unnouinceput 6y agoIf you're going to spend $400 for a Jetson, you might add another $100 and just get a powerful tablet and bet better performance

- unnouinceput 6y agoThe price difference though...
- pstadler 6y agoCheck out the upcoming Turing Pi 2. Seems very promising in every regard. https://turingpi.com/ https://turingpi.com/
- 1996 6y agoRockpi M4V2, not ideal on RAM but does the job with eMMC or SD or NVMEe boot after reflash
- mceachen 6y agoOdroid has a 4gb with sata ports: https://www.hardkernel.com/shop/odroid-hc4/ https://www.hardkernel.com/shop/odroid-hc4/ The new pi compute module has an 8gb model with a pci-express slot that can take nvme: https://www.raspberrypi.org/products/compute-module-4-io-board/ https://www.raspberrypi.org/products/compute-module-4-io-boa...
- nuker 6y agoSeeedstudio ODYSSEY X86J4105800, $190. It has 2x M.2 slots and they have 5x SATA M.2 card too.
- myhf 6y agoMany systems based on Rockchip RK3399 have a native SATA/nvme interface, but only go up to 4GB ram.
