I was doing some research and found this,
The Onn 4k Pro with the S905X4 scores 35,357 score in the benchmark
compare that to the best S905X4 running CoreELEC you get a score of 57,819 with the vontar x4
I’m using results with the same CPyhon version
that’s a (57,819/35,357=) 63.5% improvement using CoreELEC.
So using the ONN 4K Plus with the S905X5M scoring 48,810, and applying the 63.5% improvement using CoreELEC, we should see a score of (48,810*1.635=) 79804.35
The Onn 4k Plus only has 2GB RAM but the pi4 2GB and Pi4 8GB are only 0.5% difference in score but that’s using the same OS, the improvements probably be a bit higher?
The Homatics Box R 4k Plus (with the S905X4-K which does FEL + 3D) scores, 57,778, giving the Odroid C5 a potentially theoretical 38% faster chipset
Just to give a comparison the S928X-J on the x96-x10 pro has a score of 191,621
You get 8GB RAM and 64GB storage, and according to Odroid themselves the bigger the storage the faster the speed of it

well you most likely should get the 8GB EMMC (since it’s needed according to Portisch and according to this post
https://forum.odroid.com/viewtopic.php?t=23453
You are better of getting a fast microSD card, something like the Samsung cards.
But the 64GB on the X96-X10 will b pretty fast and that scores 191,621, which will make it (191,621/79804.35=) 140% faster than the Odroid C5 in single threaded python speed (if my guess is correct)
anyway just speculating and thought to share

EDIT: something else I found, if you look in that odroid wiki you will see
they are comparing a SanDisk with the EMMC, the Sandisk is the Sandisk Edge
https://www.mouser.co.uk/ProductDetail/SanDisk/SDSDQAD-016G?qs=EgF7oUuTQmrxxaRr8zFE%252BA%3D%3D
and I found this RPi thread that has the sandisk Edge comparing to the Samsung pro plus
https://forums.raspberrypi.com/viewtopic.php?t=358803
“Also, here’s genuine Sandisk Edge 128GB A1 U1 C10 class card in comparison:-
Sequential write speed 27397 KB/sec (target 10000) - PASS
Random write speed 879 IOPS (target 500) - PASS
Random read speed 2518 IOPS (target 1500) - PASS”
I’m guessing the Random read speed is most relevant to boot speed?
so Odroid are saying that EMMC is around 78% than the sandisk
and from the Pi forum the samsung pro plus will have boot load times as
(322518/4678=) 17.2 second to
(352518/4678=) 18.8 second
basically it should be close the EMMC speeds.
I always thought EMMC is faster but the data says a fast card can probably just as fast if not faster, especially if you are getting say a 16GB EMMC card
the samsung pro plus goes on sale in the UK all the time, the 128GB card was as low as £8.39 last December
The 8GB EMMC cost £20.40 , not including delivery.
You’re probably better of getting the 8GB EMMC and then get a Samsung Pro plus when on sale £12 for 128GB is common, last year the 256GB went for £17 in black Friday sale
