Nokia N8 GPU compared, again

The OpenGL ES Benchmark is a benchmarking application written to test the abilities of a mobile device’s2D and 3D graphics rendering capabilites as it relates to speed/efficiency of use OpenGL ES API’s.



Open GL API’s are used in a large number of consumer electronics including but not limited to mobile phones & consumer gaming systems. Due to their use in a number of mobile operating systems as the official graphics rendering API’s it allows a significantly higher degree of cross-platform/device comparisons to be made in lieu of  OS-to-OS differences.



Through my regular forum hopping, I chanced upon an image showing a comparison between a number of currently available devices and other devices still awaiting release. The image clearly shows that the N8 is definitely among the top contender with regards to graphics capabilities. However, just looking at the GL benchmark homepage and top 5 available, one would be inclined to believe that the N8 is eclipsed only by the Samsung I9000.

Fortunately, drilling deeper into the results data as shown in the image below shows rather clearly the N8 leading and handily beating the I9000 in a number of different tests comprising the overall benchmark. One may argue that this is due to differences in resolution, but given that the resolution difference between the two is equivalent to a factor of  5/3 or 1.66667 times more pixels that the I9000 has to push compared to th N8, some of these tests indicate almost a doubling of performance with the N8. Given that the I9000 running a 1GHz “Hummingbird” applications processor and a PowerVR SGX 540 GPU widely accepted as top of the current class, it must be said that signs look promising with regards to rendering capabilities of the newest Nokia imaging king.

Of course, benchmarks alone don’t determine the speed at which the UI will run or even what the user’s experience with the device will be. This sort of performance of the  GPU though would play handily into Symbian’s favor with its GPU accelerated UI, something which  Android seemingly lacks. Hopefully Nokia and developers can both capitalise on this promising piece of HW.

Another thing to note would be that the GPU has been confirmed yet to be a broadcom GPU most likely the same BCM2727 being bandied about the internet as evidenced by the following screens. Note the line GL_renderer which mentions “VideoCore III HW” the same core found in the BCM2727.

More information on the Broadcom GPU/VPU can be found here.

Edit:

The Iphone4 has been added to the GL Benchmark site as of today

http://www.glbenchmark.com/compare.jsp?benchmark=glpro11&showhide=true&D1=Apple iPhone 4&D2=Nokia N8

The iPhone is better at textures by a noticeable margin than the N8 but seems worse at skinning and lighting.

Caveat: There are quite a few Extensions and optimisations for the Iphone 4 when compared to the N8

    i think it is the really because the resolution of the screen. 480p vs 360p. Hummingbird is the benchmark right now, high performance paired by low power consumption. I hope that N9 will get it!

      Assuming that performance and number of pixels have a linear correlation with one another at low pixel levels which I’d speculate is the case, then the difference between GPU performance should only be around 1.667 with the N8 getting the nod, but in a lot of these cases the N8 is doubling the performance of the I9000

        Yes, but do not forget it is Android+TouchWiz3.0 vs S^3. The software is lighter for N8 hardware. Nokia, we want Hummingbird or A9 for N9! lol

    Nice post Andre 🙂
    You have also shared plenty of knowledge with us, thanks..!

    hey, why do you all forget about preatty shity cpu in n8? Don’t you think that having the best gpu never used at max and having a too slow cpu is too bad for a user!?

      Looks like you don’t understand how these things work. As said MANY times before, Symbian is such a very well engineered OS that you can put it in MUCH lower spec hardware than you’d need for Android or iPhone and it still runs like a dream. This shows why Google and Apple are still beginners at making mobile devices, something Nokia has been doing for 2 – 3 decades.

        I can only imagine how fast Symbian would be if it had more power under the hood. I’ll be more than happy to sacrifice a little battery life for that.

          You’d be in the minority then, you wouldn’t believe how many people walk around with battery packs for their iphones for example.

            Beauty of all nokia phones except for this sheeple model: you can just carry an extra battery in your wallet/pocket and swap on the fly.

            Which is why C7 is far more interesting then N8. Mostly same specs, but easily swappable battery.

    Do you have a link to the actual specs pages you’ve got the images of, or more high res images? It’s hard to see the details 🙂

    Also, don’t see the iPhone 4 listed in the first image, that would be an interesting comparison with the N8!

      Edited to show the iPhone 4’s results 🙂
      It’s still using an optimised SGX 535
      Enjoy 🙂

    Roger Johnson, Will Meego OS be as well engineered as Symbian? Also, is the negative criticism of symbiam based on the lack of newness and lack of apps from the ovi store? Thanks,Dennis

    Um, the results page looks considerably different now, with some Samsung devices clocking in nearly 2000 FPS in some tests. :/

    Hello everyone. I was surprised to see the result. I am a little confused because of the spec of the GPUs. N8’s Broadcom BCM2727 handles 30millions triangles/sec while Samsung Galaxy S’s PowerVR SGX540 handles 90millions triangles/sec…. So, from these numbers, PowerVR seems to win. Did I miss any other important information here? **sorry for the bad English. 🙂

    • Rant

      No it’s the Hummingbird CPU that handels the 90 million triangles 😉
      The PowerVR does around 22 million.

        Thanks for the reply, Rant. So, if Hummingbird alone can handle 90 triangles, what makes N8 stand out in the test?

    Isn’t Galaxy S have their framerate locked at 56 fps? Some of these benchmarks are little weak. It needs something powerful like 3DMark.

      I think the N8 has the refresh rate limitation of the display removed for reasons of scoring higher. 5000+ on HD ES is not realistic. also it is a community upload on glbenchmark.com so it cannot be trusted source of info
