EDIT: 

After investigation it is clear that the DEMO is really more an DEMO, and not usable as bench - because CPU bound limit, very huge cpu loads generating and moving that particles.

 

NEW:

From here : https://github.com/FlexMonkey/MetalKit-Particles

 

compiled app 2Mill final version:

 

Screenshoot shows low cpu usage but very high (full) GPU load = i think diff gpus should perform different, compared to the demo below.

12 FPS GT  740

20 FPS GTX 650

NEW 

some new METAL playground N-body Metal demo   :) , well known as cuda, opencl bench - now computes with metal - but i see that more as an demo,not as an benchmark

threadwidth + maxthreadspergroup may very between drivers/gpu models and are shown as info

 

Key s switches between METAL devices - if you have more than one.

Info: Metal is limited to 60 FPS - if you run in that limit you can use key + to get more bodies (up to 96K)  = more gpu work, less FPS

MacMini6,2 with HD4000

 

1,000,000 = 25 FPS

2,000,000 = 14 FPS

3,000,000 = 9 FPS

EDIT: That was from 10.11.1 (15B42)

 

====================================

 

UPDATED for OSXMetalParticles_2Mill_final

 

MacMini6,2 = 23 FPS

Congrats @mitch_de!

Thanks for your hard work  ^_^

 

 

Hey @blackosx, thanks for your test with Intel HD, I'd ask here if someone else had done a test with Metal + HD 4000.

Now i know that Metal works in this video cards.  ;)

Most work by the  https://metalgl.com , i found that stuff, compiled (only changes were changing particles count handling)

 

To bad, that using same bench but with OpenGL ES instead of Metal the app crashes.

Their framework (to use metal, used by the demo) cant use OpenGL, only OpenGL ES - would be interesting to compare Metal FPS against OpenGL (even ES) FPS.

Up to now goal of Metal is to reduce cpu load and because of that getting higher FPS. Most benefit using Metal instead of OpenGL/OpenGL ES will have slow/mobile cpus - much less very fast desktop gpus.

 

 

thanks, mitch_de   :)

 

 

here's the same demo compiled to be used on an device that does not support Metal (particles rendering using OpenGL ES)

 

attachicon.gifParticles_OpenGL_ES_2_Demo.zip

 

Great, but can you perhaps also getting OpenGL ES is used also whenMetal device is available = force OpenGL ES?

So would could compare Metal vs OpenGL ES FPS?

I tried but then the Demo crashed. 

If it would work it would display Rendering using OpenGL ES

it will be hard to me to test as my GTX570 does not support Metal  but I'll take look

// If we won't be using Metal, disable it before creating the OpenGL context.
	// The glDisableMGL() command can  be used by the app to turn Metal off in Mac/OSX
	// configurations that don't support it. Must be done before Metal or OpenGL have been used.
#if !MGL_SUPPORT_OPENGL_ON_METAL
	glDisableMGL(GL_OPENGL_USE_METAL_MGL);
#endif

Nice! :)

So if metal is not supported the demo should not run, right?

 

I'm having the same results both from the original and the open gl one 

 

about 20fps at 1 mln 

 

P.s.

the "matrix effect" when you click it's lovely!  :w00t:

OpenGL_ES_2_Demo as my own OpenGL ES forced build crashes with same result / same reason:

But great that other user with also GT 740 could get results for OpenGL ES.

Shappire HD6850

OSX 10.11.2 15C31f

Nothing works

I've only quickly searched so I can't state how accurate this information is but a post in the link below states supported devices for metal as:

 

Nvidia – GeForce gtx 4xx and newer

Intel – HD4000 and newer (ivy bridge and newer)

AMD – HD7000 and newer

 

https://forums.developer.apple.com/message/18007#18007

EDIT: same as netkas http://netkas.org/?p=1405

I don't know how true this list is it especially when in WWDC 2015 video, it clearly has been said that all Mac late-2012 models will support Metal

 

 

Late-2012 and later 21.5-inch iMac

  • Late-2012 and later 27-inch iMac
  • Late-2013 and later 27-inch iMac with 5K Retina display
  • Late-2012 and later Mac mini
  • Mid-2012 Mac Pro
  • Late-2013 Mac Pro
  • Mid-2012 and later 11-inch MacBook Air
  • Mid-2012 and later 13-inch MacBook Air
  • Mid-2012 13-inch MacBook Pro
  • Late-2012 and later 13-inch MacBook Pro with Retina display
  • Mid-2012 15-inch MacBook Pro
  • Mid-2012 and later 15-inch MacBook Pro with Retina display
  • Early-2015 12-inch MacBook

it said that my GTX570 does not support Metal but I can launch the demo with OpenGL ES support.

After I clicked, the particles are not generated anymore but a window keep floating around. Plus, no matter I click or right-click. The number stays at 1M.
