Tegra 3 vs. A5X – Does it really matter? (via @jkhowland)

I can’t find any hands on reviews that validate Asus’s claim that the Transformer Prime gets 12 hours mobile on a charge. But if the device really has that kind of battery life then Nvidia has stepped it up big time with their chips.

For the user this isn’t just about battery, and it’s not about speed, it’s about experience.

So? Is the A5X 4 times faster?

Tim Cook announced back on March 7th that the GPU in the iPad is 4 times faster than Nvidia’s Tegra 3. It’s a little sneaky, because testing a GPU for speed is not a simple process, or even perfectly objective for that matter.

Pocket-Lint conducted a few tests to find out if Apple’s speed claims really are true.

Benchmarking vs. Real Usage

For real use cases tested by Pocket-Lint, the iPad is not significantly faster than the Tegra 3. It is certainly not 4x faster.

Pocket-Lint tested the iPad with video playback for both standard definition and high definition. They used iPlayer, Sky Go, Netflix and HD videos on YouTube. They loaded graphically intense web pages, and locally stored videos.

Where the iPad really beat the Tegra 3 was in gaming. An app called Shadowgun was used as one of the gaming test apps. The app appeared to use similar in graphics on both platforms, but was much smoother on the iPad.

Who cares what the benchmarks say?

I just want the best experience. I don’t care what the benchmarks say. I don’t care what the number on the box is. If the device is slow or laggy when I get it out of the box, the number is useless to me. The A5X is pushing 3 times as many pixels in the new iPad as the Tegra 3 in the Transformer Prime. So if they’re loading at the same rate, isn’t the iPad’s chip working 3 times as hard? Does it matter?

Will the iPad load graphics 4x faster than the Tegra 3? Probably not. But are graphics remarkably smoother on iOS than on Android? Absolutely.
