iPad A5x vs Tegra 3

Well, the new iPad is only 4x faster at 720p ish resolutions. But, the retina display is 4x that resolution, SO, it's no faster than the Tegra 3 in real world use.

Actually, given the screen resolution I'd be surprised if it is any faster than the iPad 2 (that retina display demands a LOT of fill rate in 3D games).

I'm overjoyed with my new iPad, and getting Tegra 3 performance at the resolution they have is very impressive (some great chip design there!), but frankly, the games performance discussion during the announcement keynote was a good illustration that Steve Jobs left one thing behind; a fully working reality distortion field :)

Remember that all games might not run in native resolution similar to how you can have run a game on a PC in 720p even if your screen is 1080p and thus get higher frame rate.

Actually, the iPad 3 is a tad bit faster than the Transformer Prime and iPad 2, even when rendering at their respective native resolution.

See this link. Tests than don't end with "Offscreen 720p" run at native resolution.

As if Android was not made for ARM/Tegra 3?
Not really It;s supposed to be platform agnostic, it's just always used by Android as there isn't many alternatives (though Intel are now trying).

I think maybe the closest to another custom solution is maybe the PS Vita (which I also own).

Anyway, I think there's a few interesting things to see regarding games and iOS to know for sure though what we really need is Eurogamer's Digital Foundry verdict as that'll be the most accurate gaming performance assessment.

Overall though I don't really care!! I much prefer my Vita for gaming (MLB: The Show 12, Wipeout and the future Metal Gear Solid HD are impossible, IMHO, without real controls). I just like the new iPad for pixel free reading! :rolleyes:

Unless the benchmarking app has been updated for the retina display (not certain, but I believe it hasn't), the on-screen tests are likely running at ipad-2 resolution.

So, that makes the iPad 3 a couple of percent faster than the iPad 2, even at non-retina res :O Running at full retina res is going to absolutely kill performance!

But wait, it turns out that the iPad is limited to 60fps for on-screen tests, and it turns out that this is a really easy test for such a powerful chip - it's hitting a pretty solid 60fps on every test. It's basically getting 99% scores on this test. Guess what - the iPad 3 can't beat 99%, so it gets pretty much identical scores.

Both iPads are hitting the 60fps limit on a lot of those tests, which is what makes everything except the off-screen tests totally meaningless.

Just my 2 cents: I think on its own the A5X bests Tegra 3. However, you have to take into account other factors when determining "real world" speed and power. And in doing so, the brilliant retina display which requires lots of horsepower pretty much evens things out.

Anandtech has a much better breakdown. Just running a few benchmarks is meaningless.
People should really just read the AnandTech review of the new iPad, as wirelessness points out.

Might also want to check out the 2012 iPad Followup: Galaxy Tab 10.1 LTE

It only gets grittier when Tegra 3 tablets start to come with 1080p screens.

They already gets handily beaten at 720p, so it isn't looking pretty either way you see it.

AnandTech said:
The bigger worry is what happens when the first 1920 x 1200 enabled Tegra 3 tablets start shipping. With (presumably) no additional GPU horsepower or memory bandwidth under the hood, we'll see this gap widen.

Unless it's GLBenchmark 2.1.3 you're looking at, the results will be skewed for the iPad 3 as the app wasn't running at native resolution on the iPad 3. It was still running at 1024x768.

The iPad 3 is about half as fast as the iPad 2, but in some instances it's faster than that, depending on the game. Infinity Blade 2 for example, only runs at 1.4x the resolution of 1024x768, which would is roughly 1430x1050. Close to 1536x1152 which is exactly double the pixels of 1024x768. Real Racing 2 on the other hand, which is an incredibly lightweight game, is running at 2048x1536 with more AA than before.

As has been said, check out Anandtech's reviews of the iPad 3 for thorough results.

The Tegra 3 isn't actually all that good. If you look at the new HTC reviews, the One S (with the dual-core S4) consistently benches higher.

CLARIFICATION: Benches higher than the Tegra 3 based One X.

This exact topic is being discussed in AndroidForums and as expected the opinions are the exact opposite. Its actually funny comparing the comments on this and that thread!

Sure, the opinions will be the exact opposite, but you cannot argue the facts. Since it has already been shown that games on the iPad are not required to run at full resolution, the A5X technically has the ability to run more graphically intensive games at the same resolution as the Tegra 3 devices.

No opinion can refute that.

The one thing Tegra/Nvidia has going for it is the Tegra Zone where games are developed specifically for that SOC.

All games are developed specifically for the iPad, Apple doesn't need a Tegra Zone equivalent. The new iPad was just released, and we're already seeing better graphics in our existing games. Considering the top graphics on iPad 2 still haven't been matched on an Android device, let's wait a few months and see what the devs can come up with.

My comment about the Tegra Zone was not really related to how it compares to the iPad. It's more of a benefit for Nvidia equipped tablets vs. other Android tablets using Samsung or Qualcomm SOC's.

The only games that are even going to be able to compete with the new iPad are going to be Tegra Zone games...at least for the near term.
