Tegra 2 has 2.5X graphics performance of iPhone A4

Written by Fuad Abazovic

71 million triagles Nvidia vs 28 million

The A4 chip used Apple's iPad and iPhone 4 is a really nice 1GHz clocked Cortex A8 based part. Nvidia's Tegra 2 is a 1 GHz dual-core and it appears to pack a lot of graphics power.

We got a sneak peak at the graphics performance of Tegra 2 and this well kept secret is a secret no more. According to official tech documents Tegra 2 has a Peak Triangle Rate of astonishing 71 million triangles per second while the Power VR SGX 535 graphics core used in the A4 is capable of delivering 28 million triangles per second. Samsung’s Galaxy S i9000 and Google’s Nexus S both have the same Power VR SGX 535 GPU capable of 28 million triangles.

At this peak rate Tegra 2 looks 2.5 times faster in churning polygons out and the chip its available today. Tegra 2 phones and tablets should be out before the end of Q1 2010. Let’s not mention Google Android's name in vain here, as the developers are reportedly a bit late with their new tablet OS aka Honeycomb.

In case you saw in game images from Infinity Blade or id Software's Rage HD games for iOS you will probably agree that they look astonishing, but bear in mind that you can do 2.5 times better graphics on Tegra 2 based phones and tablets due its superior graphics performance.

You can check just released video of Optiums 2X Tegra 2 phone from LG vs Galaxy S and confirm the speed up claim, here.

The only concern is if Nvidia can sell enough Tegra 2 based phones and tablets to make it matter in the big scheme of things. We all know that Nvidia has a history of convincing developers to go its way in graphics and it could certainly apply these long friendships to mobile games. However it's still a matter of selling sufficient numbers of Tegra 2 based products to create a viable market for the developers.

"out in Q1 2010"

Can't be as good as you think then as I haven't seen any phones use it yet!

CORRECTION!

The Galaxy S has a PowerVR SGX 540 inside, which delivers 90 million triangles.

http://en.wikipedia.org/wiki/Galaxy_S

Come on. This is basic stuff. Do the readers have to correct the journalist's posts for mobile devices as well?

Uhm, the Wikipedia figure appears to be based based on this article:

http://androidandme.com/2010/03/news/samsung-galaxy-s-hummingbird-chip-to-have-3x-gpu-power-of-snapdragon/

...which was largely discredited by a bunch of people who read and commented it and referenced pretty good sources.

In any case thanks for your feedback

First of all Fudo, bloody PROOFREAD your 'articles' before posting them.

Secondly, the earlier commenter is correct about the 3D performance of the Galaxy S. The LG Star loses to the Galaxy S in 3D graphics benchmarks.

Where Tegra delivers some power is the CPU. Power being the appropriate word, as it draws too much of it and the battery life will suck. It'll suck bad.

The main problem of course is that Android just can't compete with iOS in the software stakes. Apple can do so much more with less power. A bit like AMD, really.

Idiot !

Samsung Galaxy S and Nexus S both have VR SGX 540 GPU which is capable of 90 billion triangles ! Not 28 ! Which means that Galaxy S GPU is more powerful than Tegra 2 also !!

Thanks for your feedback as well. Your opinion is very well accepted, but still, you may want to watch this:

In case you are wondering what this is, it's an Acer Stream vs a Galaxy S, on Qualcomm's Neo Core benchmark. Please note, that the Acer Stream features a Snapdragon at 1Ghz, which is not some insignificant mobile soc.

As you can see, the Galaxy S managed a 215% performance of the Stream. I do know that the Snapdragon has nothing to do with PowerVR, but still, 217% on Qualcomm's OWN benchmark, should show something about the Hummingbird being SGX 540 powered, no?

Galaxy S has the hummingbird CPU which does have the PowerVR SGX 540 and delivers 90 mio. triangles...

but wait untill Orion comes out which is a dualcore to follow Hummingbird...it will eat Tegra 2 alive...

tegra 2 gets 67.0 fps with 2.2
galaxy s gets 55.4 fps with 2.2

obviously tegra 2 is superior
