not in a rush. I thought the xu4's were BIG/little concept so for Boinc purposes it will only ever run the 4 main cores.

That's very true but not much you can do about it though, fingers crossed the numbers work out.

My team mate Chris has a Cubieboard4 with an Allwinner A80 SOC, also in big.LITTLE.
All eight cores work -Droid's name is 'Europa' (after a Jupiter moon)- , here he's running eight WUs enigma on it:

According to Hardkernel's own -slightly juggled- performances figures (I un-juggled them for you and added the values for the Pi3):

SBC	Raspberry Pi 2	Raspberry Pi 3	ODROID-C1	ODROID-U3	ODROID-XU4	ODROID-C2
ARM family	Cortex-A7 Quad	Cortex-A53 Quad	Cortex-A5 Quad	Cortex-A9 Quad	Cortex-A15 / Cortex-A7 Octo	Cortex-A53 Quad
Speed	900 MHz	1200 MHz	1500 MHz	1700 MHz	2000 MHz (A15) /1400 MHz (A7)	2000 MHz
Dhrystone DMIPS	1006.6	2458	1262.8	2300.7	3994.1	2623.9
Double-Precision Whetstone MWIPS	358.7	711	439.6	739.3	1024.5	1005.2

There's a used Odroid-XU4 for sale on Amazon for $80 US...hmmm...http://amzn.com/B0163GEA64

Will linux-ARM and android-ARM project apps run on the 64 bit Cortex-A53?

[Silver]

If you let me know which projects you mean I'll try them on mine and see if they run Dirk

[Dirk Broer]

A shining example of a 32-bit ARMv6 (original Rapberry Pi with ARM11 SOC) application that also runs on 32-bit ARMv7 (Raspberry Pi 2 with ARM-Cortex-A7) is Enigma@Home. Another I can think of is Seti@Home.
My guess is that it will run on the Raspberry Pi 3 too (64-bit ARMv8 archtecture/instruction set, running a ARM Cortex-A53).
I also guess that a re-compile of the ARM applications, optimizing them for ARMv8, will give better results for the Pi3.

Raspberry Pi 3 versus Hardkernel Odroid C2 (both quad-core ARM Cortex-A53):

]]

Feature	RasPi 3	Odroid C2
SOC	Broadcom BCM2837	Amlogic S905
Speed	1200 MHz	2000 MHz(rated)-1500 MHz(real)
Dhrystone DMIPS	2760 (theoretically) 2441 (Hackaday)	4600 (theoretically) 2624 (Hardkernel)
Double-Precision Whetstone MIPS	711.3	1005.2
GPU	VideoCore IV @300/400 MHz	Mali-450MP @700 MHz
RAM	1GB LPDDR2	2GB DDR3
LAN	10/100 Ethernet	Gigabit Ethernet
WiFi	802.11 b/g/n (2.4GHz)	requires USB dongle
Bluetooth	Bluetooth 4.1 LE	requires USB dongle
eMMC	No	Yes

For the 3.14 version of the Raspberry Pi I'd like 2 GB RAM (better make it 4), a SATA port and an eMMC connector...
As both WiFi and Bluetooth are already onboard, I'd glady give up on two USB ports.
Given the fact that the RasPi3 runs at 60% of the speed of the Odroid C2, I am more impressed with the RasPi3 figures.
Who knows what water-cooling the Pi3 might bring in terms of overclocking performance....

The latest on Odroid C1+:
Remove the Jumper on J8, if you don't use the USB OTG port as a power input.
It will reduce the power consumption and heat significantly. My guess is that it's the black thing on the edge of the board:

Notice that the heat sink has grown to C2 proportions in this iteration

The latest on Odroid C2:
Remove the Jumper on J1, if you don't use the USB OTG port as a power input.
It will reduce the power consumption and heat significantly. My guess is that it's the black thing on the edge of the board here too (next to the HDMI connector).
On older editions of these boards those jumpers were nowhere to be seen....

Notice that Hardkernel has dropped the rating of the CPU from 2000MHz to 1500MHz. It seems to be kernel-related, higher settings are ignored. It also affects other AMLogic S9xx products...

I was given an Odroid-C1 (old model) for free, so I am going to test it against the worst performing ARM boards that I have active at the moment: the venerable Raspberry Pi 2 Model B.
I also got a Banana Pi M2 (original model with Allwinner A31s), and a -probably defect, according to the previous owner- Cubieboard4, unfortunately without PSU.
As the two other boards had PSUs that were slightly below specs I will order new 5V/2A PSUs for the Banana and the Odroid, and 5V/4A PSUs for my -by now two- Cubieboard4's.
The Cubieboard4 should be able to run against the Odroid-XU4 -in theory.

According to Hardkernel, the Odroid-C1 should be able to beat even the Raspberry Pi 3 Model B, so we'll soon find out just how good their marketing department really is.
Either they have the goose with the golden eggs, or they sell a load of bull shit. They claim a 30% advantage for the Odroid-C1 over the Raspberry Pi 2 in a range of -manipulated to fit the same Y-ax- benchmarks
How do they do it? To gain a 30% advantage in benchmarks they tested a stock Raspberry Pi2@900MHz against a stock Odroid-C1@1500MHz, so the 30% performance was gained using a 66% higher clock. But these benchmarks and their differences between them have been presented in such a way that it sheds a benign light on the Odroid-C1, how will the two boards compare in BOINC?

For the time being I replaced the Odroid-C1's old, DIY 14x14mm heatsink with the 40x40mm heatsink with fan that came with my Odroid-XU4 -which means that the optional big passive heatsink of the XU4 -aka XU4Q for Quiet- will also fit. I had to take the XU4 fan out because it almost died, but it runs in the same housing with fan that the competing Pi 2 runs in, so the 40x40mm heatsink will get enough air.
If the test runs well I'll try to fit a 52Pi Ice Tower cooler on the Odroid-C1 and overclock it to its said maximum of 1824 MHz...

I've updated my two PI2's to the newest Raspbian Buster, and the results (BOINC MIPS-wise) are again astonishing:

New MIPS, please! -part two

Raspbian version	Linux kernel	BOINC version	Floating Point MIPS (Whetstone) per core	Integer MIPS (Dhrystone) per core
Jessie	3.6.11	7.4.23	364	1,292
Stretch	4.9.41	7.6.33	614	11,941
Buster	4.19.50	7.14.2	634	15,719

BOINC MIPS seem to be closely related to Bogo MIPS and presently go up like they're named Bitcoin MIPS...

Lets run it again for kernel 5.4.79, BOINC-Client for Raspberry Pi OS is still 7.14.2
Raspberry Pi 2 @1000 MHz
750 2/3/2021 9:08:32 PM Benchmark results:
751 2/3/2021 9:08:32 PM Number of CPUs: 4
752 2/3/2021 9:08:32 PM 712 floating point MIPS (Whetstone) per CPU
753 2/3/2021 9:08:32 PM 17469 integer MIPS (Dhrystone) per CPU

Odroid-C1 @1500 MHz, kernel 3.10.107, BOINC-Client 7.16.6
82 2/3/2021 9:02:17 PM Benchmark results:
83 2/3/2021 9:02:17 PM Number of CPUs: 4
84 2/3/2021 9:02:17 PM 994 floating point MIPS (Whetstone) per CPU
85 2/3/2021 9:02:17 PM 17562 integer MIPS (Dhrystone) per CPU

As the Odroid-C1's Amlogic S805 is clocked 50% higher than the Pi 2's Broadcom BCM2836 for the benchmarks above, it is no more than logical that the MIPS are higher too.
And it is not only the CPU that is clocked higher, the GPU of the C1 runs at 600 MHz, while the Pi 2's GPU has to do with 250 MHz.
The Odroid-C1 uses DDR3 RAM @792MHz, the Pi 2 LP-DDR2 RAM @400MHz
But as the Broadcom BCM2836 Cortex-A7 is the better chip when compared with the Amlogic S805 Cortex-A5, the difference is less than the clock speed would suggest.
The Odroid-C1's 994 floating point MIPS is nice, but if it scaled like the clock speed it should have been 1068. This is because the Cortex-A7 has a higher IPC value.
The Odroid-C1's 17,562 integer MIPS are nice too, but it should have been 26,203 to impress. The Cortex-A7's higher IPC (Instructions per Clock Cycle) strikes again.
Still, one has to bear in mind that at the time of its introduction the C1 stood against the Raspberry Pi Model B+, with its single-core Broadcom BCM2835 ARM11.

It looks like it would have no cooling issues.

[Dirk Broer]

It looks like it would have no cooling issues.

I know of three -visual- iterations of the Odroid-C1/C1+, one without(!) heatsink -the original, like the one I have-, one with a fair-sized aluminium heatsink -the first C1+, and one with a slightly bigger black heatsink, the present model.

The most incredible is the fact that the C1/C1+ can even be overclocked to 1800 MHz! I'll try that later....

Bad news for my Odroid-C1/C1+/C2 plans:

"We are sorry to announce the discontinuation of the ODROID-C1+ and the ODROID-C2 products that have been sold since 2014.

The C1+ and C2 single board computers have been adopted as control devices in the equipment of many B2B customers and have been used in various fields.
However, since Amlogic's old CPUs, S805 and S905, are no longer available, we inevitably post this news of the discontinuation of the C1+ and C2 boards as a regretful notice.

About 10,000 C1+ stocks are being secured and sold, and C2 is producing about 20,000 units, and it is likely to be available from February 17th.
According to the sales trend of the last 3 months, it seems that the quantity can supply about 4~6 months, but it may be consumed more quickly.
We tried to secure a larger quantity, but the problem of supplying semiconductors that struck around the world became more difficult for a small company like us.
This is the quantity that we have secured with our best efforts, so please understand.

When all of the above quantities are sold, the C1+ and C2 models are no longer available.
If possible, please consider positively adopting the new C4 or N2+ models. The new models are expected to have no supply problems in the next 3-4 years.
Thanks,"

So, should I invest in the Odroid-C4? To paraphrase Ludwig von Drake: "There are two answers to that question, and they are both NO"

1. The Odroid-C4 comes at the same price as the Odroid-XU4, but the performance is less.
2. The Raspberry Pi 4 Model B with 4 GB costs less and performs better.
