OMAP 4460 vs A5...

[Droid800]

The exynos and a5 have just as much in common as they do with the omap. Unlike the a4 Samsung is not involved with the a5 in any way

That's not actually true. Though Apple has moved some of the manufacturing to another company, the A5 was still developed with Samsung's help, and were, up until recently, produced solely by Samsung.

heres something to ponder before I get off here for tonight, Why do you think Google picked the OMAP over all the rest? It obviously must have something going for it.

Because its an off the shelf component available to any manufacturer, and its based on current technology (unlike the S3), just like I said...

I don't feel like copy and pasting it here, but this is why I think google made a good call choosing the omap.

I am pretty sure that the chipset was designed by that arm manufacturer that apple bought 2 years ago, and am also nearly 100% sure is is fabricated using TSMC's 28nm process. (I know because this is why the next gen desktop gpus got pushed back to q1 2012, apple was using all of TSMC's production and no other foundry has a working 28nm process yet, the global foundries is close.)

If you want somewhat of a comparison then check out these videos of a SGS2 vs. iPhone 4s. Benchmark test will show the 4s as being better but real world test favor Samsung.

The A5 chips is made by Samsung and is based off of the Exynos, just like how the A4 was made by Samsung and based off the Hummingbird.

If it was the A5 was based on the exynos then why is the primary differentiator of the exynos (the mali400 gpu) not present in the A5? All SoC's use identical cpu designs and share similar layouts of audio processors, video encoders/decoders, ect; that does not mean they are based on each other. Additionally the A5 is at a different manufacturing node from the exynos (A5: 28nm, exynos: 32nm), this is not an easy change.

Contrary to popular belief, apple actually does know what it is doing hardware wise and can design more than pretty cases.

When did I say that Apple didn't know how to do hardware?

I read your posts in the other thread and I fully agree with you. BTW you know your stuff man kudos

I didn't mean to imply that you thought that. It just seems like a common sentiment in the android community at large

There is a 0% chance that the A5 is on the 28nm process. If it were they could have kept it clocked at 1 GHz and you would still see a good jump in battery performance. At its 800MHz (under)clock we should see a very noticeable improvement in battery life. We don't see any of that and Apple actually increased the size of the 4S battery a bit. Its just on par with the 4 battery wise. the 28nm process represents a 2 generation jump compared to 45nm. The efficiency gains are going to be immediately and easily noticeable.

here's a more recent article:
Samsung Ramps Up 28nm Apple A6 SoC Production Says Report - Softpedia

Also The current gen exynos is on the 45nm process too.

 

[equake]

All current ARM SoCs are made on the ~45nm/40nm Process. The Qcomm Snapdragon S4 Krait SoCs is one of the first to out a 28nm 2nd Gen Chip. For the most part the A5 has the superior GPU against most competitors in the current generation even against the Mali.

 

[ottscay]

No one is using a 28nm process in a handset right now. Apple is waiting on 28nm fab to come fully online so they can make an LTE radio for the iPhone 5 that won't suck down as much battery juice. In one way they are smart to wait for it (everyone hates short battery life) but they are also risking further marketshare erosion (because people make purchasing decisions based on more obvious upgrades, and also LTE is fast enough that many will sacrifice battery life to use it).

Apple will probably be first off the line with 28nm SoCs, but they aren't there yet. The A5 apparently has not only the beefier GPU, but some other custom circuitry, like a fully pipelined FPU. If you guys want a good write up of it Anandtech generally does the best overviews of the nitty-gritty of SoC design, like in their iPad 2 review.

Edit: It's also worth noting that it's not so much that the Tegra 2 GPU sucked, but that it was almost a year late in shipping. What would have been cutting-edge in Q2 2010 was sort of meh in Q1 2011.

Perhaps I think of it too differently to a lot of you.

My thought is that Nexus series phones aren't made to be the Android super phone but to be a "referent" phone to developers and manufacturers. More like a phone to guide that this is what they should look out for before coming up with new phones or apps.

And this time they have set a few new standards:
(1) Android phones from now should use 720p as native resolution
(2) Physical touch buttons should be gone

.. Hmm.. it's a bit late and I can't come up with more. But this is what I have in mind. The phone isn't going to be a super phone in the first place anyway. The purpose was to set a new base standards for manufacturers who want to embrace Android 4.0.

The A5 will prove to be better in every way.

Except for nvdia, they have an awesome gpu

Didn't Google say they designed ICS to optimise the OMAP?

I also read that vzw lte radio is tricky to make work with certain processors. Hence the delayed an redelayed bionic then the very delayed Xoom 4g upgrade and Samsung's delay getting out their lte tablet. The more I think about it the more I think other service providers will get a differently spec'd nexus.

Anyway I "thought" I remember reading a Google article saying is would initially be designed to utilize the omap processors.

 

[greydarrah]

Discuss, which one has the upper hand?

I don't know why you would want to discuss this...the Nexus has the 4460 and it will run great. If you think the A5 (whatever that is) will be better, you'll have to wait on another device.

How exactly Apple cab be first with 28nm chips when they don't have their own FABs. Samsung manufactures chips for them. Don'y you think Samsung will make sure they got theirs first?

Apple pumps a lot of money into new fab operations - they will put a lot of money up front (which dramatically lowers the risk for the manufacturer) in order to monopolize the output for a significant period of time. Samsung isn't the only place working to produce 28nm - if Samsung wants to get the deal they simply have to make the goods available on Apple's timeline, otherwise they'll already have funded someone else to do it.

When you have more cash on hand than any other tech company and the largest ability to leverage economies of scale (remember their mostly just selling two phones) you can go a long ways towards monopolizing a new technology. Fortune wrote up a good piece on how they leverage their economic clout to control supply chains: How Apple became a monopsonist - Apple 2.0 - Fortune Tech
