I ordered the basic model which states the CPU is "Intel Atom X5-E8000 2.00 Ghz" so imagine my surprise when my dmesg shows the actual clock speed is "CPU: Intel(R) Atom(TM) x5-E8000 CPU @ 1.04GHz"! Turns out that the number they list on their site is something called "burst speed" which is .... what exactly? That seems openly misleading to the customer, although it is partially my fault for not researching the processor (I didn't expect a company to present it so misleadingly). I bought one of these expecting good performance. I write multi-threaded bioinformatics programs and was considering scaling up with some UDOOs, but it turns out the UDOO is actually slower than my raspberry pi 3! Here's my rpi3 results from a standard run of one of my programs: real 2m40.261s user 10m2.740s sys 0m0.330s And here's the results from the same program, with the same arguments, compiled the same way on the UDOO: real 3m11.864s user 11m58.485s sys 0m0.328s (On both platforms, I compiled my program with -O3 -pthread on GCC) Considering I could buy two or three rpi3s for the price of the UDOO X86 basic model, and the UDOO draws more current than the rpi3, I am pretty disappointed with this result. Live and learn, I guess.
