We have just recompiled our RadiAnt DICOM Viewer for ARM64 platform and thought that we could share some interesting observations regarding Microsoft's new baby.

We took our trusted Surface Pro 6 (Core i7, 16GB, 512GB) and our new Surface Pro X (SQ1, 16GB, 256GB) and took them for a spin.
On Surface Pro 6, 64-bit and 32-bit versions were benchmarked, whereas on Surface Pro X, we ran 32-bit and the new 64-bit ARM build.
The same volume (512x512x288 pixels) was opened in the 3D VR viewer on each platform and the movie of a rotating volume (120 frames) was exported in 360p resolution.

These are the FPS (frames per second) values we obtained:

Surface Pro 6 - 32-bit: 0.226
Surface Pro 6 - 64-bit (COLD): 0.344
Surface Pro 6 - 64-bit (WARM): 0.312

Surface Pro X - 32-bit: 0.0917
Surface Pro X - 64-bit ARM (COLD): 0.354
Surface Pro X - 64-bit ARM (WARM): 0.347

Another interesting aspect is power usage. We measured average wattage during idle and load, comparing ARM64 on SP X with 64-bit on SP 6:

Surface Pro 6 - Idle: 3.5W
Surface Pro 6 - Load: 32.1W (avg), 40.0W (max)

Surface Pro X - Idle: 3.0W
Surface Pro X - Load: 10.7W (avg), 11.0W (max)

Having the above, we can calculate power efficiency in FPS/Watt (idle wattage is subtracted from avg watttage during benchmark):

Surface Pro 6: 0.011
Surface Pro X: 0.046

Conclusions:

1) ARM64 on SP X is marginally faster than 64-bit on SP 6 Core i7 (3% in favor of SP X).
2) The power efficiency of SP X is 4x better than SP 6 (ARM64 vs. 64-bit)
3) Thermal throttling exists on SP 6 (10% performance hit). There's virtually no throttling on SP X.
4) 32-bit on SP X pretty much sucks as far as CPU-intensive tasks are considered (being almost 4x slower than ARM64 version).

The ARM64 build of RadiAnt has not been released yet. We will be uploading a beta version in a few days.

This seems like a huge step.
Did you try to test your new build with https dl winehq org wine-builds android
on your phone?

Would be interesting.

Not yet. But we'll certainly give it a try ;-)

hi, in the list of DICOM archives is it possible to add a space beside the easily changeable data in which it is possible to comment on the data with some comments or comments to personalize a category of personal research?

Microsoft deleted your post in the Surface Pro X forum as SPAM/advertising. They also deleted a 3 year old post in the Surface Pro 4 topic.

@hello

Currently its possible to only add "keywords" to organize your local archive: https://www.radiantviewer.com/dicom-viewer-manual/keywords.htm

@AFriend

I guess it was not the right place to write our experience with Surface devices...

I want to try on my android with wine.

I want it on Wine On samsung Dex

Unfortunately Wine for Android does not work on many Android devices (including ours...). So we couldn't even test it. If anyone has an Android phone/tablet with working Wine, you can unpack ARM64 version of RadiAnt by using silent installer command with 2020.0 BETA installer:

RadiAnt-2020.0.0-Beta-33180-Setup.exe /S /BITS=64ARM

The files will be installed to Program Files/RadiAntViewer64bitARM. Now you can zip those files and transfer to your Android device with working Wine.

How about comparing them at say 95F ambient temp, typical max spec for operation by computer makers? That could be interesting!!

So .. I did try on wine on android, but did not succeed. When the program is run, it shows an error, with a box (𛅺) character instead of the error message. I only tried on my phone, but maybe I will try to debug on my old android tablet.

What about Surface Go2?

RadiAnt should work fine on Surface Go 2. Provided that you get out of the Windows S mode
(where installations are restricted) into the normal Windows 10 mode.

how to get out of the windows S mode?

I just bought surface x just because you support windows arm version

after using it I would like to thank you for the great work on that app

it worked like a charm

Thank you for your kind words, Abdullah!
We're glad to hear that there are happy Surface Pro X users out there :-)
