Unity for Intel Atom CPUs ?

Hello,

after the Samsung Galaxy Tab 3, Asus MeMo Pad 10 FDH also uses an Atom CPU. Is there any chance Untiy will support Atom CPUs in the near future ?

 

I would guess no. All of those devices should ship with libhoudini, otherwise they are quite useless.

 

That would be really useful. I recently bought a Samsung Galaxy Tab 3 for development purposes. But when I tried to build from Unity to my Tab 3, it didn't work. I realized it was because of the Intel Atom Processor. There must be some way to debug to an Intel based processor, because I downloaded one of my published apps from Google Play, and it worked on my Tab 3 although the app was built with Unity and ArmV7

Thanks, Andreas.

 

You did build&run or did you build and then install the .apk with adb?

 

First I used Build Run which I used to do with my SG III. I then tried to Build the .apk and transfering it to my device and it worked. I found out, that the Tab 3 actually emulates the ARM processor, to run those apps. Pretty interesting

 

I'm a bit confused by this ARM vs ATOM issue. Are you saying your Unity app will RUN on an ATOM device, but you just can't use it for development/debug?

I really don't want to get into a support conversation with my customers "oh, sorry, you need to get an Android that uses ARM not Intel ATOM." They don't even know what that means. Talk about a deal killer. I am trying to decide the platform for my next app right now, really hoping to use Unity3d, but massively concerned about compatibility here.

Unity, why aren't you addressing this?

 

Your Unity app will run on an Intel ATOM device. You can't use USB debugging directly from Unity though. To debug on an Intel ATOM device, you have to make a build of the app, and then transfer the app to the device manually. You can do this many ways: ADB transfer, Bluetooth, dragging the app into the storage of your device and use the device's File Manager to install the app, there are probably also tons of file sharing apps on the Play Store that could be used.

So, it's certainly possible to use an ATOM device to develop Unity apps.

Do you know if this causes a performance issue? Specs wise the Kindle Fire HD and Galaxy Tab 3 have similar hardware except for the CPU - but the Kindle is running my project at nearly 2.5 times the frame rate. Is it because of this emulation? Doesn't seem to be too much info on the Galaxy Tab 3 + Unity.

 

I'm not exactly sure why it runs slower on Tab 3 10.1. It could be the Intel Atom processor that isn't optimized for playing games. The CPU is what actually "runs" the game, so as far as I can see on https://developer.amazon.com/sdk/fire/specifications.html it looks like they use another type of processor which is probably better optimized for games. So yeah, they probably don't emulate the apps on the Kindle Fire HD which makes it run apps faster

 

Hey just to point out that we're having huge performance problems with Galaxy Tab 3 7.0, which is NOT running Intel Atom. So it is possible that something else in the Galaxy Tab 3 range is affecting the performance. Interestingly we had it running once with "normal" faster speed, and it seemed to be ok if the device was plugged into PC while running the game. Maybe there's some kind of power saving system in all Tab 3s, which makes games run slow? On the other hand, Tab 3 7.0 is running a rare GPU which could be the cause too for us. Huoh... so many different devices!

BTW I am running our heavy game ok on Intel Atom based Motorola RAZR i (XT890), though it's using WAY more memory than some other devices such as Galaxy S2. So yeh it'll run even though it isn't optimized. Did nothing special for that either, just built the APK normally by using just Unity. I haven't tried profiling it yet though. (Interestingly Unreal Engine 3 has support for Intel based Androids - we'll until they dropped supporting Android completely..)

 

I'd like to bump this thread as I recently bought a Galaxy Tab 3 for development purposes and it definitely suffers from performance issues. My iPad 2 runs my game at a solid 60fps, but the Tab 3 struggles to maintain 30fps (or what seems like 30).

Is it the ATOM to ARM emulation, or just poor samsung software optimization?

 

Bump. Got major performance issues with Galaxy Tab3 7". Does it use the ATOM processor, and if so are there any plans for Unity to support non-ARM devices? I'm working on an Augmented Reality demo using Vuforia, and no matter whether I build run from Unity or install the apk manually the framerate is disasterously poor.

 

http://en.wikipedia.org/wiki/Samsung_Galaxy_Tab_3_7.0 not according to that (1.2 GHz dual-core PXA986 (Cortex A9) or 1.7 GHz dual-core Snapdragon 400 Krait 300)

 

i have a intel atom n455 1.6 GHz into a mini laptop hp, it run very well the unity engine, but it dont render any model in the aplication, it run the gamemode without problems, but the build dont show me models, just the standar void of unity ed scene editor. what could i do in roder to play a unity game in my intel atom n455? it support Dx11, opengl 1.4, have win 7 32 bits, and can run aplications like critical strike (unitygame) without problems, but i cant built my own game, or run a aplication in my atom, i builded an aplication in a i3 and run perfectly, but same aplication dont render on my atom, its an atom problem i know, but i want to use intel atom.

 

Not sure how off-topic this post is getting, but... I can help, since I have a Dell Mini 9 (Atom-N270 powered netbook) with unity on it. (Got it working a few days ago! ) Where's the issue occurring? I assume you mean a built game.

 

it happens in all buildings, and web aplication ever gives me a "several conection error", i can fabrik a scene and look the same scene in game mode perfectly, but build aplication isnt work, well i build in my athom and run in other computers like my other pc that is an i3 (so motherrrfuk**g fast) but if i build in any pc the aplication do dont work in my atom. the solution maybe is suggest an opengl1 unity vertion, well unity 5 runs perfectly in my atom but its something that i cant explain, i mean, i dont know why the builded dont render nothing in my hp mini with intel atom n455.

well reallily the hp mini is a very powerfull pc, i make sure that the problem is not a power problem, maybe is just a compatibility problem, i hope some developer chek it and say to me any solution, i think ist going to be a settings solution.

I am assuming that you are trying to get unity 5 to run builds properly on your hp mini....
In that case, see if building with unity 4.6 works. I am not sure if Unity 5 has an atom-specific problem, I don't use 5 on my atom powered netbook.

 

it works?

i did it some time ago and it works perfectly, but the license isnt the same... :v

 

Ya, that was the compromise I had to take to use Unity on my netbook. Point being, I haven't tested Unity 5 on this netbook yet, and despite people saying it won't run, it's always worth a try.

One thing's for sure; I am going to need both a hard drive and a RAM upgrade first before attempting...

 

a sheap ($290) and powerfull i3 (integrate graphic card of an 2013 i3 support opengl 4.0, like ps4) fix a lot of problems !! .-. or buy an i8 with the most bestial graphic card in the world ($????)... if dont want that you can simply try to instal a grapic card to your atom (i think that the case suport it, an opengl 2.0 graphic card could work, all can fail in this way) ($free-?-??).

Pd: ll:{ fail intel atom, FAIIIIL!!!!
