AnandTech reviews the iPhone 5: A6’s Swift processor clocked at 1.3GHz, taken through paces

The Apple iPhone 5 has been out for almost a month now, and while that might seem like a lot of time, it has been barely enough for tech gurus from AnandTech…
This is a discussion for a news. To read the whole news, click here

It's worth to buy :)

I feel like owning buying one... Apple why didn't they clock it at 1.6 and use 4gpu? And overclocked Gpu to 527mhz, This phone would be ultimate..,

Lol because it is an Apple silly :D
It would be much better if you stick back to android :)

Because it would increase a lot power comsumption and the iphone has only a 1450mah battery, and increasing the battery capacity that would have meant to increase the size and weight of the phone.

No matter what processor they are using like every phone, The Mapple myphone 5 will be smoked by The Windows Phone.

Would have been cool if they were Krait cores....

I agree... I want to see a comparison with the PadFone 2 and the new LG

What would have been cool about it when Swift is clearly shown to beat Krait phones in the benchmarks?
20. sheik (Posts: 249; Member since: 12 Sep 2012)
I am no tech nerd... but iPhone 5 does not exactly beat Kraits, in Gsmarena, Xperia T scores better than i5 in Geekbench, and GLBenchmarks(Egypt)....
26. TylerGrunter (Posts: 864; Member since: 16 Feb 2012)
I have to defend Victor here. I am a tech nerd and can tell you two things:
Krait and Swift (iphone cores) manage to get similar values in Geekbench 2 only cause krait cores are clocked at 1.5 MHz while Swift are clocked at 1.3 MHz. That means that the Swift will be more battery savvy than then krait (As Anand points out)
Most of the tests show that the Swift is around 10% more powerful than the Krait, not much, but not bad.
For GLBenchmarks: Xperia T is the GLBenchmark 2.1 while the iPhone 5 is the GLBenchmarks 2.5. the second one is around 3 times more stressfull in the GPU.
Conclusion: the chip in the iphone is around the same as a dual krait PRO at 1.5 GHz with Adreno 320, MSM8960T (Xperia T has the Krait with Adreno 225, MSM8260A), but a bit more battery friendly.

which "krait" are we talking about? dual or quad pro?
27. TylerGrunter (Posts: 864; Member since: 16 Feb 2012)
Krait refers to the CPU so it doesn´t really matter if you are talking about the power of individual cores, as both have the same CPUs (that´s what Victor is probably referring to).
The iphone is only match to he dual kraits, it has more or less the same power. The quad-core kraits should be around 60% more powerful than the A6 in CPU and more or less equal in GPU.

The Iphones are good phones but i hate apple with a passion because they are way overpriced and i feel they take advantage of people who they marketed to.
phone simple and works, so lets overcharged

Android phones are already moving towards s4 pro with adreno 320 which gives A6 run for its money both in cpu and gpu department. And newer generation exynos, tegra and Omap are yet to arrive.
8. TROLL (banned) (Posts: 4851; Member since: 13 Apr 2012)
Even those would fail to Exynos. The S4pro. S4PRIME. S4+, if the A6 was clocked at 1.7ghz with Pvr543mp4 Adreno don't stand a chance.
13. nofear (Posts: 149; Member since: 22 Jun 2012)
A6 is dual core processor, Apple did not give more than 2 core. TimTebow, you are right! on this one, Anandtech got Tim cook's a$$.
16. PackMan (Posts: 277; Member since: 09 Mar 2012)
Also, the android benchmarks scores are lower than they should be. Anandtech has apple fetis. Just look how long their idevices reviews are.
18. darac (Posts: 2156; Member since: 17 Oct 2011)
What the hell is with that ridiculous notion about the Intel chip?!?
That said, yes the A6 is, overall, the best phone chip on the market right now.. but S4 pro is just about to roll out, and it is already a superior solution. And by the time A7 gets reviewed, this apple chip will see many other soc's taking over the charts.
So objectively, it's nothing to write home about.
BTW, in Geekbench - the only true cross platform benchmark - A6 is significantly outperformed by the quad core Exynos 4 (Galaxy S 3 and Note 2)

"That said, yes the A6 is, overall, the best phone chip on the market right now."
- On what basis can you say that ? Exynos in s3 and snapdragon s4 outperform A6 in many benchmarks and that too is highly software dependent. Only in GPU does A6 beat others.
22. darac (Posts: 2156; Member since: 17 Oct 2011)
Overall, meaning CPU+GPU performance, power efficiency and connectivity.
Compared to dual core Krait, seems like Swift takes a victory on all three fronts.
Compared to quad core Exynos, it gets partially beaten only in CPU department.
Anyways I've just read the whole review and thoroughly enjoyed it.
Glad to see that the author basically made the same point that I have:
" At a high level, it would appear that ARM's Cortex A15 is still a bigger machine than Swift. Swift instead feels like Apple's answer to Krait. The release cadence Apple is on right now almost guarantees that it will be a CPU generation behind in the first half of next year if everyone moves to Cortex A15 based designs."
23. PackMan (Posts: 277; Member since: 09 Mar 2012)
Fair enough. But I am not sure about the power efficiency and connectivity part. Hard to measure.
30. darac (Posts: 2156; Member since: 17 Oct 2011)
Yeah, that's a point alright.
Actually I think I need to correct myself.. overall (since geekbench is the best overall cross -platform measure we have ) the Exynos 4412 still seems like a more capable computing machine.
Swift holds up hugely thanks to the GPU.
Swift has dual core Krait edged out slightly in CPU and convincingly overall, thanks to much more powerful GPU and Java script optimizations.

So android fans, it looks like we are using superior, smart and more power efficient technology in the palm of our hands.
