Well this is $250 so I think building a next gen board for under $200 is unlikely

yeah $200 is probably too much for many people.
Still a Snapdragon based board "could" be interesting. As long as it's supported with the freedreno drivers, it could be a very interesting board.
Doesn't always have to be high end.. The U3 is still an awesome board and it the SoC is going to it's fifth year on market :)
Maybe a Snapdragon 801 or something?

The 801 has plenty of horsepower and would be less expensive.

this is what arm says in its brief preview on armv8:
Image

So even they are facing it in their preview, - if it would be so 'acceleration' as it names it, why the hell wouldn't it replace all those additional (costs) SoC "engines" (the same useless but bringing ugly problems of support btw)? It looks like those mega super acceleration instructions are kind of macros - what they really do - fuck up the whole idea of RISC intruction set. Instructions must be easy to implement, semantically elementary and run fast (in the clock cycle terms), ... yeah, this macro aes instruction in no way can execute fast or is semantically elemantary, it looks like a wrapper which translates inside into a sequence of more elemantary operations, cutting off any flexibility and possibility to improve it, like it might be with just the normal arm code. It hardly gives any acceleration because for this it would be needed a specific logic put on the silicon to do the only thing - aes round, sha calculations etc, this is the only way to be REALLY accelerated - to get a specific module for itself, some kind of ALU, with its own aes-ish (and sha-ish) logic. but doing that for the only ONE algorithm is so wasteful and up to date no one can see this amazing facts - where those numbers of badass acceleration on armv8 are? and they honestly are saying in their promo, to not expect this replacing those "engines". so, just macros translated internally into ordinary arm ops? with shiny "instructions" into ISA for the happiness of all acceleration shit lovers and pain of all purists and those who will deal with this in their job. what benefits are then with this if it's just a high level wrapping? maybe that that it pretty well serves as a snake oil for oversensible ones to that 'trends'? The same as jazelle, whithdrawn totally as a useless marketing garbage for "accelerating" another marketing garbage. which only has done the one thing - has complicated the already pretty clumsy architecture. Tomorrow sha3 sha4 aes2 will come up and all those acceleration shit would last as a waste forever in the ISA. But hey, there are also jpeg, png, tcp and udp, millions types of video decoding encoding, hell, there are even xml parsing - lets "accelerate" all this, thinking up freaking ugly instructions for every such a task. Cool! All is offloaded and accelarated. The cpu may go in its deeepest powersaving state to what it looks like is intended. In the end of the day, you get such an ugly shit instead of thinkful architecture, so heavily damaged by these viral marketing nonsense. RISC appeared exactly as a try to withdraw such an approach - representing 1000000 high level instructions for doing everything it turned it's a waste not giving any benefit. And now again - all want accelerated virtualization of accelerated cloud xml parsing.
It's the snake oil acceleration. And you seem buy it happily. It's sad. I thought users need just fast and efficient implementation of the cryptographic algorithms particularly. "Acceleration" comes from overall improvement of the next generation of the architecture, not from screwing up the ISA with oddities for taking momentarily effect. its a fake improvement. arm seems made it into armv8 only because intel has done such a stupidity before.

Well, impressive numbers - 825% increase compared to 32 bit. What can anybody say against this? I only fear that this is total fake. Just read this thread http://forum.odroid.com/viewtopic.php?f=93&t=17882 to see, how such wild numbers appear just as a result of benchmark inconstistency or underlying misconfiguration. Just let's look at those numbers a little bit deeper. So we have Apple's A7 clocked at 1.3-1.4 GHz. Geekbench gives terrifying 846.2 MB/s AES throughput for the single threaded variant (this is 825% increase compared to some not evident from the article 32-bit counterpart). Just wow. Now, let's go in wikipedia and check out what amazing numbers the Intel's "miracle" - aesni has gotten. We know that was something. Here we are, wikipedia says that:
wikipedia the allknowing wrote:In AES-NI Performance Analyzed, Patrick Schmid and Achim Roos found, "... impressive results from a handful of applications already optimized to take advantage of Intel's AES-NI capability".[24] A performance analysis using the Crypto++ security library showed an increase in throughput from approximately 28.0 cycles per byte to 3.5 cycles per byte with AES/GCM versus a Pentium 4 with no acceleration.[25][26]

(Funny, - they compared versus Pentium 4. :mrgreen: I am typing from P4 machine btw!))
Well we have it. Just remember that last number - 3.5 cycles per (processed) byte, that's what Intel has achieved with their acceleration. It's also 700% increase by the way, but for now we just want to take the last number as a reference point. Next, considering apple's cpu running at its highest frequence - 1.4GHz (somehow wikipedia doesn't know the exact frequency of A7, is it 1.3 or 1.4 GHz, it's not strange for apple's products anyway). so we may easily calculate the analogous parameter for their implementation. So, with 846.2 MB/s of the throughput and 1.4GHz of the frequency, we have - 1.57781144 clock cycles per processed byte! (1 400 000 000 / 846.2*1024*1024). It comes out ~2.218 times faster than Intel's aesni! (if we take 1.3GHz, it gives us even more - 1.465 clock cycles per byte and 2.389 times faster than aesni). The only question here - does anyone believe those number are true. and not just weird garbage output spitted by the confused benchmark. I don't have apple's SoC to do the comparison by myself, it only leaves to believe this or not. I respect Anandtech but I don't believe such non realistic numbers. And precendents with wrong numbers in benchmarks as in the above mentioned thread only strengthen this. Also note, SHA2 which also got "accelerated" in armv8, for some reason has gotten only moderate increase of 18% in that benchmark, as opposite to the 845% of aes and 245% of sha1. This 18% look much more realistic what may be achieved from it.
Speaking of cryptoengine modules on a SoC, your links only approve how messy is to support all the imagined variety of different "engines" and their quirks. It's the same as with the support of deeply closed and not documented gpus. Only worse by even lesser degree of the actual support.

Just FYI:

The S805 in the C1 can do AES encryption/decryption without involving the CPU at all. Its integrated into the DMA engine.
http://dn.odroid.com/S805/Datasheet/S805_Datasheet%20V0.8%2020150126.pdf
page 57
Inline processing is also supported to allow data from DDR to be processed using an AES, Triple-DES or CRC module before being placed back into DDR memory.


I recall reading somewhere the S905 added SHA1/SHA2 checksumming in addition to CRC.

Nothing is faster than 0% CPU use. ;)

One benefit of a HW crypto engine is power savings. That might make it sufficiently compelling for mobile SoC's. However, in the case of servers (another market addressed by ARMv8-A), it might not be justified, due to poor support by apps. It's much easier & more likely for app & library developers to add support for a standard instruction than to support various SoC-specific crypto engines. Regardless, it's a moot point, because the instructions are there.

That said, it'd be nice if this thread didn't turn into a flame about RISC purity and speculation about rigged benchmarks.

Architecturally speaking, a DMA crypto accelerator is the superior approach: you have to transfer memory to encrypt/decrypt; so do it at the memory level. GPU's are all non-standard, but they have the same goal. In the same way all cryto hardware needs is a driver. Not using onboard crypto hardware is like not using a GPU. You can get the same job done on a CPU but its MUCH slower.

Its ironic that Linux violates the Unix principle of "do one thing and do it well". The monolithic linux kernel + drivers tries to do everything and does little of it well! :lol:

Adding and removing crypto APIs should be as trivial as adding and removing a library. Its due to the monolithic nature of linux that standards for things non-x86 do not get a chance to arise. ARM boards are not saddled by legacy hardware design dating back 30+ yrs like PCs are and can innovate with features like DMA crypto. This is relevant to this discussion as the $200 price range is PC territory ...

mattbot wrote:and speculation about rigged benchmarks.

... and there are no benchmarks measuring DMA crypto against AES-NI CPU crypto. :D

This is simply a statement of my own personal reflections on the matter. I completely understand that hardware crypto is not a solution for everyone. With the proper API design, it should be completely transparent whether your crypto is using hardware, special CPU instructions, or traditional methods. If linux got out of the way, there would be no obstacles, political or technical, preventing that.

It's likely correct at 3A, power for the additional sensors and any connected hardware. It's not all for the CPU.

SO-DIMM slot -> more price, worse size. In my case: NO! I wish more memory: 4GB+, but only if the price is correct, and if it don't hurt the size. Ideally 1GB by core.

In a followup to some of the discussion here, we now have a good indicator of what the price range is for the board being asked for in this thread:
http://phoronix.com/scan.php?page=news_item&px=AMD-LeMaker-Cello
AMD Opteron A1120 quad-core Cortex-A57 processor running at 1.7GHz, 2x DDR3 SO-DIMM slots, two Serial ATA 3.0 ports, Gigabit Ethernet, two USB 3.0 ports, one PCI Express x16 3.0 slot

able to mount in a mini-ITX / micro-ATX chassis.

set to retail for $299 USD


That price does not include the memory, the required heatsink/fan, or a GPU.

I do not understand who uses these boards and what they do with them. For a lower cost I can build a PC that has more USB3 ports and more SATA ports that will likely outperform it. Is there some killer application that only runs on Cortex-A57 that I am not aware of?

accelerated cryptography however it's accomplished would compel me to upgrade my XU4. USB 3.1, or 4k like the C2, would be nice but less compelling.

I would prefer odroid worked on improving software (kernel 4.4 for all, Debian Jessie for all, and drivers for the C2) instead of considering another board.
They only have so much time in the day so let's let them focus on improving the current stuff instead of pushing for more hardware.

I would love to get DisplayPort instead of HDMI so you could have the option to chain two monitors (if there could be two video ports then it does not matter, but I am guessing that would push the price up). It would be perfect for desktop computer.

Silent cooler is the only feature that is important.

Everything else is already up to spec. or will improve automatically.

USB3 is good enough for everything IO.

More RAM if 64-bit.

Sure, but they go for like $70 which for the xu4 is doubling the price. For that price ($150-200) you can start looking at other options. Also, I have read in the specifications that the Exynos 7 (the one in the S6 and possible candidate for a hypothetical xu5) does not have DP but has capability for 3 monitors through hdmi, so I am wondering if including a second hdmi would require anything other than the connector and if it would increase the price noticeably or not.

Is there anything better for a next-gen ODROID than a Cortex A-72 4-core + a Mali-T880 MP16?

Add to that 4GB LPDDR4 @ 1333MHz, and I'm SO sold!

Exynos M1 "Mongoose" or Tegra X1 are probably better, the Tegra X1 probably not when it comes to pure CPU performance, but most likely when it comes to GPU performance, it should support OpenGL not only OpenGL ES and has about 512~1024 GFLOPS compared to Mali 880 with about 256~300 GFLOPS.
SnapDragon SoCs might also be a lot faster. Adreno 530 goes up to 500 GFLOPS as well.

I should have said "at less than $100/150 price tag" :P

I know that for 600 bucks I could even buy a friggin' Nvidia Jetson X1 :P

Cortex-A72 + Mali T880 MP 16 probably would cost around $250-300 as well, since it is extremely high end. I highly doubt you can get that anywhere for $100.
That's why I pointed out other high end devices.

For $100~150 you probably get something like a Cortex-A57 + Mali 7xx GPU.

According the designers of the Up-Board even-though the stated limit of the x5-Z8350 is 2GB, they say it is possible to have 4GB:
"Though Intel only declares 2GB RAM in the x5-Z8350 specification, it does not mean that 4GB RAM is not possible; we have done some trials by putting 2GB RAM in 1GB RAM design architecture, so we do believe 4GB* RAM is feasible and we are going to do it. It is going to be beneficial to applications which require a lot of memory resources, such as video streaming and others. (*we will verify if z8350 provides the same characteristic as z8300 to upgrade to 4GB RAM once Intel ships z8350 sample )"

It consumes just over a C2 and just under xu4.
It would be nice to see a benchmark of c2/xu4/intel

Does not say what the max clock speed or memory limit is. It also does not have a GPU or video engine. The big question is how much will it cost?

It's more oriented switch based usage, like banana pi r1 and fitlet X.

I'd like to see:

- Replacement at $80 price bracket with at least 20nm Exynos 5433 with 3GB DRAM

- A higher $100 price bracket with 14nm Exynos 8890 (maybe 7420) with 4GB to 6GB DRAM

Native SATA would be a big plus.

Prefer Exynos since graphics drivers are better for things like emulators vs Snapdragon.

Priced any higher than about $120 and it gets heated competition from the likes of Up Board.

For $100~150 you probably get something like a Cortex-A57 + Mali 7xx GPU.

According to cnx-software, there will soon be some smartphones featuring helio x20 selling for 170 - 200$

http://www.cnx-software.com/2016/04/07/ ... o-x20-soc/
So if you put that soc in dev board instead, it might be not as costly as you thought.
But the main problem is still the same, what about software support ?

i think a lot of op`s are missing the point of the whole idea surrounding these boards low powered boards with processor power

i think the A57 or similar cpu is in line with this topic really ..the a-72 is very attractive but at a cost from what i can see here

i would like to see 4G ddr ram and more usb3 ports and either optical audio support..well high end audio support as the c-series has

sata support..although we have been managing with usb support for hdd`s..hence the reason for extra usb 3 ports..

sata ports also bring in a new factor from the generic power supply`s having also to power a sata hdd/s so the power supply would adequate to power the drive/s as well as still

once again it comes back to cost and these boards have to balance the factor into mind

This company has SD820 board. More development aimed though. Wish there was a SD820 or exynos 8 in odroid form factor. Looks like the SD820 has some pcie lanes as well.
