This year's small computer - Page 7

fivemack · 2015-06-14, 10:00

I do have an energy meter - but it's in an outbuilding and I don't have a webcam rigged up to point at the energy meter yet, so I've got point measurements and couldn't very easily record energy use at each core count.

A little further up the thread I mentioned that I was seeing 30W at idle and about 83W flat-out.

For the aid of anyone else reading this: 'efficiency 73% on 5 CPUs' means that the dimensions-per-hour figure for five CPUs is 73% of five times the figure on one CPU.

I was updating my post while you were answering because I did understand how you calculated your "efficiency".

I'm considering this build:

I already have the PSU and RAM from previous combo purchases. Anyone here have experience with AMD's AM1 line?

Anandtech reviewed a Xeon-D on a SuperMicro board and got an idle power reading of 31W, very close to that of fivemack. http://www.anandtech.com/show/9185/i...r-soc-champion

AnandTech tested the Samsung Exynos 7240 (including detailed power consumption). Produced on Samsung 14nm FinFet it needs less power to operate at a higher frequency than the Samsung Exynos E5433 (on 20nm planar).
5433: 4x A57 cores @1.9GHz => 7.39W
7240: 4x A57 cores @1.9GHz => 4.12W
7240: 4x A57 cores @2.1GHz => 5.49W

I hope Hardkernel is going to use it in a new Odroid board :P .

I'm not really suprised, it would seem Samsung is reserving the 14nm high-end production capabilities for it's own products (and maybe Apple).

It are interesting times with Samsung, Qualcomm and Intel battling it out on the high-end low power mobile market. At the moment Samsung seems to have the best smartphone SOC, but that could change when Qualcomm releases their own ARM core implementation. Or maybe Intel have an ace up their sleeve...

Some interesting computing equipment based on 64-bit ARM SoCs is supposed to become available for both rental (e.g. http://www.design-reuse.com/news/378...processor.html) and purchase (e.g. http://www.cavium.com/newsevents-GIG...rocessors.html) this quarter.

Cavium ThunderX seems to be gaining traction even in HPC in the form of CPU + NVIDIA Tesla: http://insidehpc.com/2015/07/e4-comp...arm-with-gpus/
