Nvidia tegra k1 Denver vs Apple A8X Comparison

[xxballerxx54]

The Apple A8X benchmarks are out and it is quite impressive. It has 3 cores at 1.5 GHz and has 2gb of ram. I made thi thread to see what you guys think of it compared to the Tegra K1 benchmarks, and if it was impressive or not. Also do you think Dolphin would run better on A8X? I know neither Soc's are out but just make a guess of which device would dolphin run better on

Speculation until someone makes a Dolphin fork on iOS

Yep, and likelihood of that ever being available for devices that are not jailbroken? Zilch.

First Geekbench scores for the new iPad today came in ~1800 for single CPU performance, less than the K1 Denver which scored ~1900. Still questions to be asked about how the rather unique architecture in the K1 might affect performance in emulators, but from what we know for sure right now it looks like it will edge the A8x.

Considering this is essentially a first-gen CPU from Nvidia, it is quite an achievement knocking the A8x off the top of the mobile food chain for per core performance. On that basis would expect Nvidia's solutions to improve and widen the margin over the iPad going forward...

As of right now the A8X looses anyways because of the K1's access to full GL4.4 and some serious speed ups. However, if LLE Aaudio was fully implemented with the seperate thread option, the A8X would win because it has 3 physical cores. At this point its all speculation, the desire is not there for an iOS version, and the platform isn't either.

K1 was running at 2.5GHz in the test.
This frequency won't be sustained in apps like Dolphin.

A8X is 1.5GHz. It blows K1 out of the water.

And I think vanilla A57 will do this too.

The K1 is pretty thermally stable, at least the quad core variant was. The dual core variant is supposed to be even more stable so maintaining full clock is probably doable. Not to mention both cores would have terrible usage anyways because of how dolphin works. It all depends on how improved the Denver cores are over A57's.

Or how downgraded Denver is.

Downgraded? Nvidia doesn't do downgraded. They are at the top for SoC design.

Yeah, sure.

It's hard to argue when the Shield Tablet is currently the fastest device when running dolphin, with the N9 as second place. Apple SoC's are very fast, no doubt, but for emulation they fall flat, because Apple is against emulation, so the SoC designs are not friendly with any kind of emulative type load. Nvidia has the advantage here because they have their refined OpenGL 4.4 driver stack, which provides noticeable speed improvements. Even if the dolphin was ported to iOS, the A8X simply won't perform the way you expect it to.
