With this methodology the shown numbers are worthless. The Amlogic BSP implements thermal throttling so it’s important to monitor temperatures and clockspeeds at the same time since if throttling occurs consumption decreases as a side effect.
Can you provide consumption numbers made with stress-ng --cpu 6 --cpu-method matrixprod while monitoring system behavior (e.g. running sbc-bench -m) in parallel?
You have the equipment S922 with a connection option SATA M2 for comparison with the M2 NVMe ?
This is written in the documentation (description) VIM3 that when you turn on NVMe USB 3.0 is disabled. This is a known issue of s922. Everyone knows that.
I haven’t yet seen how specifically u-boot is implemented to be used on VIM3, but I don’t see a problem in adding the necessary driver to u-boot. Also, there is already the first implementation of u-boot-2019 for s922, given that u-boot is the Linux kernel, I don’t see a problem with adding a PCIe driver (as it was done for EDGE to the mainline kernel).
Those that exist outside of small vendor communities. With an average SATA port and an average M.2 SATA SSD we get today sequential and also random write and read speeds that exceed what’s possible with NVMe SSDs on Vim3 due to the simple fact that S922 is only capable of a single Gen2 PCIe lane (and really fast NVMe SSDs want a Gen3 x4 interface which is an 8 times faster host interface). The bottleneck here is simply the board’s PCIe implementation.
But as you pointed out there’s no alternative to using NVMe SSDs anyway since S922 is not SATA capable. Though people thinking about NVMe speeds they’re used to on other platforms will be disappointed as can be seen by the fio tests Gouwa did.
And I don’t think everyone is aware of this major S922 limitation that USB3 will be gone once PCIe/NVMe will be used even if it’s mentioned somewhere in the docs. That’s why I pointed it out again.
This was the missing piece of information (I didn’t pay close attention to anything around S922 the last months). Yep, with mainline u-boot PCIe/NVMe support might work and a bootloader in SPI NOR flash can run an OS directly from USB or NVMe storage.
For me personally the most important information around VIM3 launch is Gouwa’s NVMe test since this confirms that PCIe on S922X is usable. Unfortunately Khadas only focuses on fancy and cool looking stuff with full feature set resulting in high prices. But for me as a ‘use case first’ person with NAS and server use cases in mind a VIMS (S for server or NAS) would be the greatest device in 2019.
Simply remove everything not needed, add an ASM1061 for two SATA ports (and plan a Pro variant with an Marvell 88SE9215 for four SATA ports), combine this with a stackable enclosure allowing for efficient passive cooling (see ODROID HC2), 12V input and done. The OpenMediaVault HC2 image gets installed +200 times a week so if Khadas would manage to provide this at a competitive price (same as or below HC2) and manages to keep full compatibility with VIM3 and allows for a stackable design supporting 2-4 3.5" SATA disks then this would really sell well (if Khadas is faster than Hardkernel here).
IMO the best use of the single PCIe lane on S922 with the specific highly energy efficient NAS and server use cases in mind.
I don’t have a VIM3, so this is just a guess. According to my data , the distribution of the real speed (with the active use of read/write when compiling large projects) on S922 is about this. SD cards, eMMC, USB 3.0 (obviously good media that meet the parameters of USB 3.0), NVMe. This is not a 100% guarantee of such behavior, it is only a General trend and much depends on the specific parameters of the equipment used.

So if I understand well the contest, the normal price of vim3 (basic or pro) are 40$ more than current displayed price. The contest offers great discount, but I’m a bit disappointed compared to the price of Odroid N2.
The main advantage is the nvme port even if the single lane will limit performance and I agree that a version with sata ports will provide be a great NAS solution.
Yes I will compare your tweet in #1, with the twitter username provided in #2.
in #2 i buy the Coupon an write my twitter name in the notes field
“hope this is correct?”
Yes this is correct.
in #3
how you know the correct email for the discount code? the email i used in #2?
Because my twitter mail is another one
