Dual Core vs. Quad Core

[Kevin OQuinn]

would someone show me where Samsung announced that sprints version would be an S4 krait processor - and not the 5250L? would love to see this, really.

and please don't take this as me being a smart ass or bashing, I'd really like to see where Samsung said its Sprint version (which always got the better S, SII versions of the Galaxy) stated the Sprint version, whether its 16 or 32GB versions, was getting the Krait(S4) processor.

I was still under the impression that we had to wait to June 20th to see the specs...which might include 2GB RAM as well......
personally id like to see 5250-L(te) as sprints processor. but...I have a suspicion that this isn't the only android phone we will see from Samsung...this year, if its a Krait

It's widely accepted that US versions will share specs with the Canadian version, which is Krait with 2gb of ram.

Sprint is going LTE, so it stands to reason this is the version they will get.

Just about every review or article written has stated the us version will be getting the s4. Japan didn't get the quad and neither did Canada. Both got the s4 as everyone expected. Everything I've read says we will get the same.

I just don't see Samsung using 3 different processors in the same model.

I have not read a single review or comment from any sort of reliable source that states the USA would receive anything other than the s4. No where have I ever read or heard the gs3 linked in any way to the 5250.

Yea...at this point I will take better battery life over better benchmarks, better performance.

If that means an S4....so be it. Especially if it means better battery life with 4G. Like in the PC world...I never had a want or need for quad core. Now that they are putting out less heat...I will be getting one soon.

See...back when the Droid 1 and Eris were out.....yea phones now are alot better with performance. And its easier to see and feel. I really dont believe the difference will be felt as much between dual and quad core. That plus the software is better. Better coded software should be what we all want.

I have the HTC One S with the S4 processor, and it is a very nice processor, with one caveat: While it has a decent integrated GPU, no one really programs games for it. Dungeon Defenders crashes while loading, and any other graphical intensive game is designed to work with Tegra 2 or 3 GPUs. At least, any worth mentioning...

Still, the processor is very fast, otherwise.

initially i was upset NA would be getting the dual core...

but when i saw it was officially annouced that the dual core will come with the 2GB of RAM i was happier..

i read good things about the S4 and LTE in my Area (Toronto on Rogers) is pretty good.. i just did a speedtest and i got 41mbps..

i have the SGS2 LTE (skyrocket) and it lags when opening some apps etc, but the ROM i am on is pretty good and makes my phone much faster.. with the SG3 touchwiz it flies through screens with little to no lag.

i am pretty stoked for this phone as i have already pre ordered it and it will arrive on June 20th ; >

I never did anything with this video that I shot at CTIA, but if you are worried about the S4 chip, I wouldn't be. The detail and frame rates on this demo were really impressive.

A video of a video never really comes out good, but in person it was really impressive.

The S3 performs much better under ICS. All the benchmarks see noteable gains when compared to GB.

While this is not an official announcement from Sprint, this is as close as it gets to confirming that the Sprint version is not getting the 5250 but the S4 instead:

Samsung SPH-L710 aka Sprint

Yes, Sprint usually has the best version of a phone, I think the Evo 4G LTE is a better version of the One X due to its added features which were popular with consumers. The kickstand was much loved from the Evo 4G and the added microSD card slot was something everyone thought the One X was sorely missing. Also, the Sprint version of the GS2 was the only one that had the more popular Exynos processor AND the bigger 4.5" screen, all this of course was due to Sprint using WiMax for it's 4G and not LTE. The E4GT also was the only version of the GS2 that had a notification LED, all this made it the best version. However, we live in a different world now. WiMax on Sprint is going bye bye, LTE is the way to go and because of this, the Sprint version will have the S4. There is just no way the Sprint version of the GS3 will have the 5250, guess we will save that for the GS4.

It's all politics. Qualcomm controls the market here in the United States. If the Tegra 3 and next gen Exynos is made to work proficiently on LTE, Qualcomm is thru.

You mean even though the benchmarks show the S4 processor beating the Exynos and being on par with the Tegra 3 on nearly all counts?

I would be happy with the S4 version, but I don't think it "beats" the quad exynos. Many of the benchmarks(real world is key) favor the exynos. A couple may favor the S4, but those were Qualcomm based tests.

I would accept "on par".
Maybe I am being picky, sorry.

I don't know much about all technical and hardware-related things, but I think the quad-core is simply faster than dual core.

Be careful about making assumptions. So much more goes into this than just number of cores.
Think of car motors.
Look at the power differences in motors with different number of cylinders. There are some 6 cylinder engines more powerful than some v8s.
A 1989 5.0 (a v8) mustang had 225 hp and the current Mustang v6 has 305 hp.

Well dual-core and quad-core each have their own advantages at this point in mobile technology.

First of all the dual-core Snapdragon S4 is a 1.5GHz processor while the quad-core Exynos is a 1.4GHz processor. So technically the dual-core can reach faster overall speeds. But quad-core does have the advantage in dealing with multitasking and will be beneficial for programs/apps made to deal with this aspect.

Beating the Exynos while being on par with the tegra 3? I think you got it backwards. Its beating the Tegra 3 and while being on par with "some" of the test against the exynos.

Every phone runs better on ICS due to hardware acceleration ( well except for the lesser single core phones like the droid X or the og snap dragon powered phones ) but my single core hummingbird got a fresh shot of redbull when i flashed ICS on it. Benchmarks went up on the exynos phones as well on ICS by another 25% so the ass kicking it gave to the S3 chip is just as bad when both are running the same version of android.

I agree with the posts that say dont assume more cores means faster or better.

Even in the PC world....when quad core first came out...it wasnt so clear cut to just upgrade and automatically be faster, better than dual core. I havent got on the quad core bandwagon on PC's yet...I may see myself doing the same thing on phones. Battery life will be the deciding factor. That and/or heat output.

I also got on the dual core bandwagon on PC's late...2008... and still there.

Its hard for us to forget the S3. Oh, the HTC Sensation, such a beautiful phone, but the Qualcomm S3, even running at 1.5Ghz is slower than my Tegra 2 at 1.0Ghz.

Now, it appears that the S4 is an improvement over the S3; however, it certainly doesn't trounce the Exynos. It may match it on some benchmarks, but you have to remember, most of the benchmark numbers we are seeing are from single-threaded benchmarks, it is very likely the Quad-Core Exynos is being hindered by the very benchmarks being used to compare these two processors.

In real-life, the Quad-core Exynos will likely be faster. Furthermore, it will most definitely be faster on multi-threaded applications. Not to mention, that early reports are that the graphics in the S4 are not up to par with what even the Tegra can muster.

Technically speaking, the Exynos is more old tech. It's basically last years components doubled up with the same GPU as last year running at a higher speed, all built on a smaller, more efficient process. The S4 uses the more modern A15 based instruction set compared to the A9 in the Exynos, and is build using the even more efficient 28 nm process. The GPU is what's holding it back a bit being still largely based on the old Adreno 220 but ramped up quite a bit with huge gains in speed thanks to the much improved memory throughput.

What everyone REALLY wanted was either the Exynos 5250 dual core (also based on A15 with the newer Mali 604 gpu, compared to the Mali 400) or the S4 Pro which incorporates the new Adreno 320. Seems like both of these SoCs aren't in the cards for any devices until Christmas rolls around or maybe even into next year.

Going back down to earth, my GS2 runs everything you throw at it without any problems, granted, it runs at a lower resolution, but the chips that both versions of the GS3 get are more than capable of running at 720p. For the most part, as long as the UI is fast and stutter free, I don't see any apps or games causing problems. It will take a while before software developers will catch up to the new processors and will really start to challenge them.

only partialy right.
snapdragon S4 wont be better energy efficiency than Exynos 4412 (S3 has better battery life than One X) due to HKMG on 32nm process of exynos 4412.
Intel developed HKMG to replace ordinary semi conductor's silicon (SiO2) so it can reduce power leakage so it runs at much lower power.
reducing size of process helps on power (so both chip's better than old 40s nm) but cuz of HKMG, Exynos 4412 is better on power consumption.

I read some user reviews of the one x in the forum and most seemed happy with the battery life, all this with a screen of almost identical size and a smaller battery and the arguably resource heavy sense weighing things down. We won't know until we see it ourselves.
