If anyone wants, I can provide the tinkerboard side of the comparison if you provide the benchmarks you wish to test and will compare against your own PI3B+, or wait until I buy a Pi3B+, which may take a while as I cannot afford one just yet.
Better act fast because within a week or so I plan to attempt something that may kill the Tinkerboard and I don't plan on buying another.
This is not a thread asking for help with a competing product, but a question about how Raspberry Pi compares. Since many people on this forum are Raspberry Pi experts, comparisons made here should be quite accurate. Since Raspberry Pi is orders of magnitude more popular for a reason, accurate comparisons should be beneficial.
The Pi3+ uses the ARMv8 Cortex-A53 processor.fruitoftheloom wrote: ↑Wed Mar 21, 2018 4:52 amThe Tinkerboard and Tinkerboard S both use the same ARMv7 Rockchip RK3288 SoC.

An explanation of the input/output parameters follows:
T/V : Wall time / encoded variant.
N : The order of the coefficient matrix A.
NB : The partitioning blocking factor.
P : The number of process rows.
Q : The number of process columns.
Time : Time in seconds to solve the linear system.
Gflops : Rate of execution for solving the linear system.
The following parameter values will be used:
N : 8000
NB : 256
PMAP : Row-major process mapping
P : 1
Q : 1
PFACT : Left
NBMIN : 2
NDIV : 2
RFACT : Right
BCAST : 2ring
DEPTH : 0
SWAP : Mix (threshold = 64)
L1 : transposed form
U : transposed form

- The matrix A is randomly generated for each test.
- The following scaled residual check will be computed:
||Ax-b||_oo / ( eps * ( || x ||_oo * || A ||_oo + || b ||_oo ) * N )
- The relative machine precision (eps) is taken to be 1.110223e-16
- Computational tests pass if scaled residuals are less than 16.0

I don't think there is any question about "best supported". The last comparison data I saw was that the Tinkerboard had buggy software and little to no support. The fastest board in the world is useless without properly functioning software.jamesh wrote: ↑Wed Mar 21, 2018 9:47 amHappy to leave this thread up and running, but please keep to the title - performance comparisons.
I expect the TB to be faster in some areas, not so good in others. We never claim the Pi is the fastest SBC, but we do like to think it is the best designed, and the best supported. It's certainly the best seller.

Thanks for running the test. A speed of 8.565 Gflops seems reasonable. Is any over clocking involved? Since you mention over clocking later in your post, I thought I'd ask to make sure. As an aside, If I'd recommend overcooking your laptop instead. Laptop CPUs are often thermally constrained. Therefore, if you add water cooling, the speed of your laptop may improve considerably.
There is currently no overclocking involved. Everything on the board is stock at the moment except for the larger heatsink I put on it before putting the poor thing in a tiny acrylic enclosure.
Three advantages that differentiate the Raspberry Pi from buying an x86 PC for $35 at used surplus or the local thrift shop is small size, manufacturer support for Linux and working GPIO. If you lose two of those, then only small size is left. At the same time, small size can be pretty compelling.
This is really the key. Lots of "Raspberry Pi killer" single board computers have come to market, and none have even managed to wound the feisty little Pi, based on the astronomical sales figures (which I'm sure eclipse all other brands combined).jamesh wrote: ↑Wed Mar 21, 2018 9:47 amHappy to leave this thread up and running, but please keep to the title - performance comparisons.

Funny you should say that because it uses the same kernel version of Debian Stretch with LXDE as Raspbian does.
As posted above they released a new TinkerOS revision this week....
Which is mostly irrelevant, as what's in the kernel depends entirely on the build settings which are I suspect entirely different for the TB since its is an entirely different collection of HW.
Fair enough, thats something I wasn't really aware of.jamesh wrote: ↑Thu Mar 22, 2018 9:34 amWhich is mostly irrelevant, as what's in the kernel depends entirely on the build settings which are I suspect entirely different for the TB since its is an entirely different collection of HW.
