Question Various sbcs best one for....

[mindwave65]

Raspi is a great general purpose computer that can give you almost everything, but for good experience you want something with consistent power. Like if I want to build a real daily use tablet. I can find one of 3 types of rk3399 sbcs an there is A FEW boards with done "big/littles" CPu setups. Like the Helios x27, but honestly wo buying thm and testing them out, is there anyway to determine which is better? And which is better? Seems like I'm the only one ever consider testing them and I get it. I am building a radpi4 based tablet/ laptop
And if I could extract them for better setup is one heyttet than the rest?

WOW proof that trying to ask serious tech questions on a phone while very very tired, is a BAD idea, for me, looking at that its like "English as a 6th language?"

ANYWAY - the bottom line is this. The RASPI is a great board and a great price for what you get. However there appear to be, on paper anyway, some ideas that SHOULD just blow it away performance wise. Yet that dosnt seem to happen,, or no ones has tried it yet.

For example RASPI4 - Quad core 1.5GHZ 4GB ram, Wifi/BT - seems like a capable but small desktop. Then you have something like the MT6797X - DECA CORE (10), in 3 groups, 2 that max at 2.6ghz, 4 that max at 2ghz and 4 that max at 1.6ghz. 4GB ram BT, wifi etc.

SO am building a "tablet/laptop" Its WAY thicker than any tablet has a need to be, but since Im using the RASPI4 as my base I have a certain thickness to deal with. The "laptop" part of it is 99% for my writing as you can see form above, I need a full keyboard. Im even working with Dragon and its alternatives and I spend 2x as much time editing as I do creating.

Then there is the battery. If man had invested a fraction of the time in inventing battery tech as we have cpu tech, we'd be driving cross country on 2 AAA's. I despise laptop batteries, and most decent tablets don't seem to have much more, so I had one built for me that seems to go a good 10hours, but its a deck of cards sized.

My question is though, if you can buy a board with the MTK6797 and you can there are several, and they are no anywhere NEAR the RASPI price, but on paper, they should SMOKE the RASPI right?

But they don't seem to. I know part of the issue is the SW. right now most big/little SOC/SBC seem to be targeted at smartphone's, and some have Linux barely shoehorned on them, but Ive owned tablets at the top of their range and they dont seem to perform the way paper says they might. So obviously androids not a serious contender either.

So am I missing something? Or is there a hole in the market there because the facts prove that the RASPI4 really IS the best solution?

any and all ideas accepted. And if you know where I can get a Big/Little board at a decent price ($100 isn't too far out, and it seems smartfly makes a heliosH20 board fpr that price) please let me know.

Thanks

I have Asus Thinnkerboard next to RPi#+, and Asus is almost 50% than RPi. Software is pretty stable, too (Debian 9), with nice-looking desktop. I'm using it more or less as a build server, so GPU performance is irrelevant to me.

 

[mindwave65]

when you say "asus is almost 50% than the RPI" do you mean its 50% faster? slower? more expensive?

Ive looked at that board since it came out and considered it, then thge RPI 4 came nd seems at least its equal if not superior, except in experience. The Tinkerboard seems to have a really good community

Sorry for confusion... My keyboard did not have lunch yesterday
I meant "faster", and that was before RPi4 release. I don't have RPi4 to perform similar tests (and honestly, don't need two HDMI ports).

ThinkerBoard community trails RPi, of course, but for me it's doing the job (ARM server, no IoT stuff, for now) pretty well.

Thanks, trust me if you saw my original post my who PC was losing its religion.

It just startles me that there are so many different SOC and SOM devices out there in cell phones and even tablets, but no one is selling JUST the boards themselves.
The RPI4 os pretty high on the list at the moment. I have an Atomic PI and its fast no questons, but its HOT and that heat sink is NO joke. I also have a Jetson NANO and although I haven't started on the AI learning yet as a "desktop" it is amazingly rock solid.

The RK3399's just seem WAY over priced compared to the rest of the group, and there doesn't seem tobe anyone who is yelling and screream,ing about how well the BIG/little architecture is solving desktop issues everywhere....
