In fact, the one change I would make to the current XU4 is to put the GB ethernet on the hub and provide a single dedicated USB3 line with the free port. Adding a ton of ports detracts on both counts as all the peripherals will under perform on USB buses. What gives the XU4 value above its cost is the amount of performance in the form factor it has. Nor is it practical to carry a PC around in your pocket. Its not really practical to run a PC off a battery. Where ARM boards shine is in doing non-PC things particular media playback and portability. I can get a PC equivalent that would outperform the specs listed in this thread for $75 (CPU + motherboard). ARM SoC boards require me to spend a great deal of time "fixing things" or "working around things" when used in a role that a PC would perform. Not mentioned in any charts thus far is TCO: total cost of ownership. The XU4 is at the upper price limit for me.

If the cost is high enough, it might be a good idea to have two boards like the XU3. Hopefully that is enough for most of the features that are listed. For myself, I would say that $125 to $150 is my price range. Also, it would be nice if their was a battery holder on the board for the RTC battery and a large enough CPU heat sink that a fan is not needed. Wireless networking and lithium battery support could also be added. I do not know if the 7420 has a built in audio codec, so one could be added if it did not have one built in. I only need 1 Ethernet port and 1 SATA port, however the other possibilities are included since there are others who would want more. Of course the more Ethernet and SATA ports that are added, the more the board will cost. There is the possibility that there could be 2 Ethernet and SATA ports if there is only 1 USB 3.0 host connector. So if 2 hub ports are used on the XU5 for USB 3.0 host connectors, then that leaves 2 ports for an additional USB to Ethernet bridge and a USB to SATA bridge, or 2 USB to SATA bridges. The 5422 has 2 USB 3.0 ports and on the XU4 one port goes to a USB to Ethernet bridge chip, and the other goes to a USB 3.0 hub chip. So, a USB hub chip could be added to the 1 USB 2.0 port so there would be 4 USB 2.0 host port connectors. I don't know the how many USB ports the 7420 has built in, so I will assume that it is the same as the 5422. See meveric's post for details of the 7420's performance. The 7420 would make a good CPU and hopefully it is “settled in the market” enough that it will be affordable. I came up with a revised and more detailed list for a Odroid XU5. 1 or 2 Gb Ethernet ports (USB 3.0 to Ethernet bridge) 1 or 2 SATA (USB 3.0 to SATA bridge) and 5V power connectors Exynos 8 needs a year or two to settle in market. Exynos 7 is probably the best shot at the moment. The Exynos M1 (Exynos 8) could be very interesting in the future with everything at 64bit (even memory 64bit dial channel) could really speed a few things up. Steps in ARMs world are not "that big" at the moment. The better GPU (Mali T720MP8 vs MaliT628MP6) should also improve gaming a lot. So generally the Exyshould be nearly 1.5x as fast as the XU3/XU4 and probably feels a lot faster due to the nearly twice as fast RAM. Vs XU3/XU4 : 2.0 GHz A15 + 1.4 GHz A7 means (2000 * 4.01 * 4) + (1400 * 1.9 * 4) = 32080 + 10640 = 42720Ĭonsidering that the Exyis also list with stock 1.9 and 1.3 GHz, instead of the 2.0 and 1.4 that we have on our ODROIDs, there could be some room for even more power on the Exynos 7 as well. The Exywould already be faster than the XU3/XU4 LPDDR4 memory with 1552 MHz (24.88 GB/s) vs 933 MHz LPDDR3/DDR3 (14.9 GB/s) nearly twice as fast RAM and at least the Samsung S6 that uses the Exycomes with 4GB RAMĪlso it's Cortex-A57 and A53 vs Cortex-A15 and A7 (A57 4.76 DMIPS/MHz) vs (A15 4.01 DMIPS/MHz) Stf144 wrote:I am looking for something with more computing power and memory than the XU4, and you're probably right that the Exynos 8890 would be too expensive.
