Snapdragon 800 Vs Apple A7

[Raptor007]

Moving to a 64 bit os is not BS. That's the reality you're ignoring.

Show me how it is going to be awesome on a smartphone compared to a desktop/notebook computer. Could it have value sure but I am not doing 3D rendering and moving massive files or requiring big computing power. It will do things faster, but it won't be so amazingly noticeable to the user.

If there is no development, then there is no optimization. That could further negate any potential advantages 64 bit could offer.

Xcode handles it all unless you're using assembly language. Then your code has to change. You just don't have to do it yourself.

Apple hasn't advertised it as such.

In the next few months I'll be likely moving to a Note 3 and 2014 Note 10.1. I'm imagining this to be quite the power couple.

Will you keep your note 8.0? I'm tempted to have all 3..but do I need all 3?

 

[Haalcyon]

Hmmm...I don't know. Now I use my Note 8.0 a lot for work. I don't see that changing.

The Order Odonata...there can be only one.

Yeah I do too.only thing I'm worried about is when I get note 3 will I use my note 8.0 less at work? As really if I get the note 10.1 I feel I won't use my note 8.0 much at home..hmmm

I might gift my Sony Xperia Tablet Z to my wife and son when I get the Note 10.1 and sell the S4 and Note 8.0 for the Note 3. Options.

Your first two points both tie into improvements in (d)encryption speed, and that is a fair point. But even with the current gen 32bit cores VPN transmission and disk encryption on mobile devices is already done in real time with no noticeable impact. And some mobile SOCs may have a separate ASIC that does the (d)encryption anyways.

I'm very skeptical as to your third point. Please elaborate on how 64bit general compute improves on recognition accuracy? It doesn't. At best it may speed things up a bit, but again not appreciably

As for your last point, there will only be a boost to FP calculation speed if you use 64 bit variables. But as I said in my original post you wouldn't want to unless it was a STEM based task and then you wouldn't be doing it on your mobile device anyways. And unless you really needed the extra precision of 64bit, which you usually don't, using 64 bit variables is actually a detriment because best case your double precision FLOPS are 1/2 of what your single precision FLOPS would be which means you are wasting compute.

I'm not saying that going 64 bit in a mobile chip is bad or worthless, in fact its not, what I'm saying is that its not as big a deal as Apple made it sound. For example, if the A7 was exactly the same except the cores were 32 bit instead of 64 bit, all the numbers the quoted for improvement over the last one would still be the same. The performance improvements for the A7 over the A6 had very little to do with the 64 bit general compute processors.

Man I missed this. My understanding on the biometric calculations was faster (notice not improved)accuracy in do the high dpi of the scanner and mapping of the fingerprint.

Going back to the Note 8 and the Note 3.

Me getting the Note 8 made me regret getting the S4 instead of holding out for the Note 3.

Now I have second thoughts about getting a Note 3 because I realize it isn't as necessary since my Note 8 is always with me. I have an upgrade I can in October or I can just sell off my S4 but I feel like what I really want is a S4 with the touchless commands of the Moto X for navigation.

You could also hold out for the next nexus phone. No telling what great features will be in it. There is no telling if the moto/google ownership could bring some of those good features to the next nexus.

I can tell you with 100% certainty I wouldn't get the note 3 if I had a note 8. I love the idea of the Note, but the screen is sometimes still just to small for note taking. Is the Note 8 pocketable at all. When I was playing with the idea of getting my tablet, the B&N Nook i hacked at was great at 7" and just small enough to go in my pant pockets.

I can't fit the Note 8 in my pockets(just tried). Note 8 also has a beefy bezel. If I am out and not working that means I am with my Wife, so she and her purse becomes my Note 8 holder.

When I am working I have a laptop bag with a tablet pocket.

I am far from being confused. This is about understanding what 64bit computing in general means. That is something that doesn't change just because Apple decided to include it in there latest Iphone. 64 bit computing is about how large a data set can be processed at once. If the phones hardware can't really utilize that increased resource then it is simply for marketing.

My point was that having a 64 bit OS and 64 bit apps on a phone with 1-2 GB of ram and other resources that don't go beyond 4GB of addressable space is useless. So not even the newest Iphone 5s will see any advantage from it. Until that happens it is a marketing stunt. It isn't like this is a PC or Server that can be customized, and there might be some unexpected potential to exploit it later. On a phone or tablets in which all of the system resources are set the upgrade to 64bit OS doesn't do anything unless the hardware needs it at the same time. Currently the only piece in the Iphone 5s that doe is the CPU.

Don't get me wrong I don't think it is really a bad thing they have moved to 64 bit computing, it is good to be prepared, but the hardware that is in the Iphone 5s wont' see some magical improvement because it supports 64 bit computing. Your assertion that there won't be any 32 bit apps on the Iphone 5s is also wrong as if third party apps aren't updated and compiled for 64bit then there are. There are also some consequences to moving to 64 bit computing. The first and biggest one is increased resource usage if you don't have the hardware platform that really needs it. The second big one is potential hit in performance when running 32 bit apps in that environment.

Until they release a device really has all the hardware needed to fully utilize it it is simply for marketing and to say "Hey we have the first 64 bit Mobile platform".

Please keep in mind I didn't say anything about the A7's raw performance. I will wait for some decent Real World test to validate that, and I suspect it will be a great performer. I was speaking directly to the effect of the new phone doing 64 bit computing.

I worked on IBM mainframes for 30 years and they went to 64 bit computing in about 1984. The only reason was the limitation on file size and partition size of 32 bit computers. The partition size for a 32 bit machine was 16mg which was a huge limitation. 64 bit allowed for a partition size of 4gb. End of story.

IBM's reason may not be Intel's reason.

By the way don't you mean from 16 bit to 32 bit

https://publib.boulder.ibm.com/info...opic=/com.ibm.zos.zconcepts/zconcepts_102.htm

Not disbelieving you or what you did, I think you were making an honest mistake.

With the release of the System/370-XA architecture in 1983, IBM extended the addressability of the architecture to 31 bits. With 31-bit addressing, the operating system (now called MVS? Extended Architecture or MVS/XA?) increased the addressability of virtual storage from 16 MB to 2 gigabytes (2 GB). In other words, MVS/XA provided an address space for users that was 128 times larger than the address space provided by MVS/370. The 16 MB address became the dividing point between the two architectures and is commonly called the line or boundary

great optimization I think

 

[jamesish]

A7 means nothing if Apple won't Put the Juice On the Chip, It's like Sending Someone a Cracker in a Porsche. yeah, ther Porsche is nice but all you're getting is a cracker.

Sigh.

Focusing on ram limitations is what was part of the concept of why Windows went to 64 bit.

The N64 was name such because it had a 64bit processor, yet the system only had 4 mega, yes megabytes of ram. For more intense games you had to buy this ram expansion pack that took you to a whole 8 megabytes of ram. That still irks me to this day.

64bit processors can handle a wider datapath so you can process more data faster at the same time. Calculations can be pulled in faster chunks.
64bit processors can handle larger integers, larger numbers means more complex calculations at a faster rate. Because the integers I am referring to are involving strings of bits.
Then 64bit can handle larger memory address, yes this can mean ram, but it can also take in larger chunks of memory to process within its own pipeline and cache.

So it wasn't just about ram. 64bit processing did help with that limitation but there was much more with it.

Apple going to 64 bit also did a couple other things.

It gave them a processor to handle biometric calculations better(Fingerprint Sensor). Also encryption technologies like high level vpns for governmental agencies require a heavy workload, so that was part of this switch as well.

But yes 64 bit processor helps a lot outside of just ram.

By the way, a lot of mid tier video cards are 192-256 bit cards. Yet most of them only come with 1-2gb of ram. The Geforce 780 only has 3gb of ram but is a 384bit card.

Why go through all that if it wasn't going to help processing at all.

It reminds me of the dual core vs quad core debate. When I first bought my PC I had the choice of a faster overclocked dual core CPU at 3.8Ghz or a slower Quad Core at 3.4 Games ran faster slightly on the dual core, but for multitasking the quad core blew it away. I think the future is about multi-tasking and now so much single task processing. But i'm not a programmer so I could be out to lunch on this. All I know is I'm still using the same quad core and it is still fast, while the dual cores died out somewhat.

Totally doesn't answer the question for the thread, but hey fun info anyways. Just ran the 720p 3dmark test on both my note 2 and my ipad 4. Note 2 ice storm scores is 3308 while ipad 4 scores is 9360. Both were fully restarted before I ran the test. Based on the antutu scores I saw for the snapdragon 800, it's about 3 times faster than the note 2, so that brings it on par with the ipad 4, roughly. We'll have to wait until someone does a definitive test.

I just tried running 3dmark 720P on my Note 3 and all it said was 'maxed out' Lol

 

[Weaser999]

Not sure if I'm doing this right. I ran the ice storm ultra or whatever and got 18436 or something like that.

 

[pappy53]

It amazes me how a dual-core 1.3 processor with 1 gb of ram can stay with or beat this beast of a phone.
I am not bashing the N3, but it just doesn't make sense. Evidently, Samsung needs to take a page out of Apple's optimization book. It looks like Moto did just that.

 

[Zergslayer69]

Well I read that the A7 is developed in house by apple so it's got special attention while the snap800 is just an off the shelf component that multiple companies use. I'm more interested in how the rumored A7x will fare against the snap800 seeing as how the 800 is the current flagship processor for android.
