bow to the new king!!! benchmarking inside note 3 takes all octo core can use all 8

[Dontazemebro]

64 bit iPhones can run 32 bit applications and apps can be upgraded to 64 rather easily according to the keynote. so there should be 0 fragmentation.


I like android tablets not so much android phones... While the Note is cool, it's just wayyy too big and I'm not a fan of man purses...

Yea but what they fail to mention is that you still get zero benefit for recoding an app meant for a 32 bit system. Actually I believe it hamstrings the OS because then now you're dealing with nearly double the size but only half the data. Which could force other issues like bad battery performance since now you're asking the CPU to perform tasks that aren't even essential to the core operation of the OS

Don't get me wrong I applaud the 64 bit but it's really only a base for better content to come later. Now imagining what that content could be? That's the game changer right there.

Does it use 1% battery per minute to do basic web browsing like my HTC One does here?

Just... no.

Code size MAY increase slightly. 64 bit doesn't mean all the code is 2x the size. Data size will stay the same, and data is where the bulk of the memory consumption is.

however, it does mean that the CPU can process operands twice as large in a single clock cycle. so battery throughput may IMPROVE (assuming the app/OS is recompiled for 64 bit) as less clock cycles are needed to do the same work. thus, the chip can spend more time asleep.

I agree, this is just setting a foundation for whats to come.

of course it's going to look like it's 4x faster then the Note 2 when Samsung is programming the device to cheat in benchmarks. Will it really be 4x faster then the Note 2? NO it will not.

really? You know this how?

 

[jrswizzle]

Thanks for the quicky and we all know exactly what cores mean and how the exynos soc uses pure arm a15 cores that clock for clock have about 15-20% instruction per clock improvement over the snap dragon krait a9/a15 hybrid

Tell that to a server farm running 64 CPU clusters using more cores for more raw power.

I would take a quad core snapdragon at 2.3ghz running 32bit over a dual core a7 64bit chip any day of the week.

The exynos octo core will also out perform its own snapdragon version and Samsung finally fixed it and it can now run all 8 cores at once!

So would you take an arm quad a15 quad a7 at 1.8ghz or a dual core a7 64 bit soc from apple?

Time will tell, but take a look at this thread posted by a member here - very good analysis of the A7, which in all likelihood is actually a quad-core chip.

No, the snapdragon 800 really is that far ahead.

 

[skratch77]

No, the snapdragon 800 really is that far ahead.

But its only 32bit!!!

 

[nickchallis92]

I only purchase 512-bit phones

 

[SlCKB0Y]

In the keynote, the guys who make Infinity Blade mentioned with Apple's tools, they were able to convert the game from 32bit to 64bit, in 2 hours. An only one dev did that task.

That's one app, with presumably full assistance from Apple and done by a very talented professional developer. What about the other 900,000 apps?

You know how many Android apps will need to be recompiled when Google makes the switch? Presumably only those which use NDK. For the rest (the vast majority) Google just needs to compile Dalvik to work on 64bit CPUs and the apps will automatically work.

How are they doing this and how do you know?

Cue in the second 'bit' war.

Remember the 90's?

I would respectfully disagree.

 

[daneoni]

I know many will say who cares but the geeks in us want to brag about benchmarks

What good is 64 bit when...

So which is it...care or don't care?

You can't pick and choose arguments as and when it suits you.

A good example. Out the gate "Super Mario World" world showed the potential and advantages of 64 bit processing over 32 bit consoles like the PSX and Sega Saturn.

Over the following couple of years the differences became more pronounced.

 

[ReanimationN]

I would respectfully disagree.

Don't get me wrong, I loved the PS1 too, but the 64 had so many instant classics.

The cartridge format really held back the N64 in some genres though, for example, the PS1 was the go-to console for RPGs.

I've still never had as much fun with a console as I did with the N64. It was so good for multiplayer games.

 

[Klosefabrinio]

if the octa core chip can use all of the 8 cores at once, it's obvious that it'd score higher. my personal experience says that snapdragon chips are better, A LOT BETTER!

 

[skratch77]

What good is 64 bit when your bottlenecking it with 2 threads and 1gb total system ram?

 

[adder7712]

Legitimate question.

Do phones really need a 64-bit processor?

 

[TSE]

And you need this processor in a phone, why??? To text??? To... call??? To... uh... web browse??? To... play Angry Birds??? Hm... yeah... that's right, you don't.

I'm sorry, but... I don't get it.

 

[Kariya]

Legitimate question.

Do phones really need a 64-bit processor?

Not really a legitimate question. Its like asking if phones need a 1080p screen on a 5" or lower display, or if phones need 4 cores or 8 cores.

There was a time people wondered if we needed more than 512MB of RAM in a computer.

If people listened to those who asked/are asking these questions then we'd still be in the dark ages of technology.

The OP brags about a phone having 8 cores then turns and question what usefulness 64-bit architecture brings to mobile. I'm sorry but...what? He even goes on to dismiss it without knowing the full details of the A7 chip. Come on.

Bet if Android was the first out of the gate with the technology he wouldn't bother questioning it.

There's nothing new under the sun?

 

[Bilalo]

Talk about fragmentation too! Apple just fragmented there Eco system way worse then android has ever been.

Now devs will need to code for 32 and 64 but versions of Facebook and twitter!

Apple said that apps are backwards compatible and will only take a few hours to become 64 bit alone. Then both will be supported depending on ios device. And 64 bit isn't only about ram, for someone talking like a geek as u said u should know better and appreciate rather than mock because your a samsung fan...

 

[throAU]

Legitimate question.

Do phones really need a 64-bit processor?

Probably not.

however, again... as per my previous post, if it means they can process operands twice as large in one clock cycle, they can maybe be clocked lower or sleep more, which could potentially save power.

64 bit CPUs also tend to come with other features, so it may not just be the 64 bit-ness that the phone OEMs are switching to 64 bit CPUs for.

with vector instructions commonplace in modern CPUs the whole bit-ness thing of the CPU is a little bit ambiguous now anyway. is it in refernce to the address size, the internal word size, the vector instruction operand size, etc?


And with regards to the N64... classic example of this ambiguity: the bus size on the N64's CPU is 32 bits. Whilst a Pentium onwards for example has a 64 bit bus.

So whilst the N64 was called "64 bit" and the Pentium 3 was called "32 bit", the Pentium 3 could actually crunch through data quicker than the N64. The Pentium 3 also had 128 bit vector processing instructions (SSE), so maybe when comparing to the N64 it should be counted as 128 bit?

5S A7 is a DUAL CORE chip that beats the G2's Snapdragon 800 and HANDILY beats the GS4 (at least my US version) in Geekbench 3.

Hey - if these idiotic benchmark wars are going to continue, I might as well brag when my side wins. ESPECIALLY when they do it with an INFERIOR DUAL CORE chip.

Lol.....you just got learned.
