What's the holdup with Samsung Galaxy S4's Exynos 5 Octa version?

0. phoneArena posted on 01 Apr 2013, 04:55

It turns out that Samsung went with the simpler and cheaper way to design 28nm chips like the Exynos 5 Octa, called gate-first, while the competing foundry TSMC designed its production capacity with the harder to implement gate-last process. The problem stems from the fact that gate-first might be easier to transition to, but gives yield problems later on, especially with complex SoCs, and that's exactly what seems to be happening with Exynos 5 Octa...

Samsung did very well to get top notch performance out of the SD600 variant yet improve battery life at the same time, so I'm not too worried about the version differences. With the SD800 and Tegra 4 only coming out in the 2nd half of the year, whatever Galaxy SIV you get will lead the performance race, but more importantly, lead the endurance test in 5"-ers.

I'm just wondering how the endurance tests will differ between the Exynos and Snapdragon variants. I want to see what big.Little is really all about. I know Samsung said that the Octa uses 70% less power than the Exynos 5 Dual, but I want to see real life performance.

GSM Arena claimed the Snapdragon GS4 could pull 3 days of use if you managed it right, I wonder if the Exynos variant would do better.

Well a Russian test said video playback does 12.5 hours on the Octa (GSMA measured 10 on the SD600) but results differ on brightness level and the actual video that is being looped so it should not be taken like a fact.

The Exynos 5 SHOULD be a bit easier on the battery, but most of the drainage still comes from screen and radios, so the SoC cannot do miracles; if you are a very heavy user, you'll charge whatever version at the end of the day (unlike the One, Z, S3, 920 or iP5 on the afternoon).

I don't know if you remember but both the One and the iP5 last longer than the SIV on web browsing, the iP5 loses a lot on talk time but other than that both phones last the same during heavy usage as the SIV losing only in stand by time, which won't be relevant on a single day of use.

Standby time is absolutely crucial cause between your browsing and multimedia and talk, one drains the battery heavily while the other not very noticeably, hence the huge gap in endurance score. You will never do just web browsing from 100% charge until 0% non-stop, so the iP5 and One going a few minutes longer matters not in real life use where all-around usage falls back considerably. That's why we have these tests to give us a good look what is real and what's hype.

The One and the iP5 don't go a few minutes longer, they go over an HOUR longer, don't come and tell me the One and iP5 will drain their batteries while sitting 1 hour on deep sleep because that is simply not true, the One got an 48 hour endurance with 3 hours of use each day, most of the stand by drain is at night, which defeats your logic by itself of them not lasting a day.

web site usage usually taxes GSIV more due to the white color usage which is AMOLED screen's weakest point since it's using the most power. Now if the websites featured, dark themed pages, it would have done much much better

I can see Intel sneaking in there and taking some market share if they build up there smaller nanometer chips and finaly puting out there quad core chips. Intel has the potential to dominate this area. I hope an american company finaly starts ttaking advantage of the smartphone revolution well besides apple but I mean hardware manufacturer not what ever apple does

In due time Intel will be there,as of now they are testing the chips slowly. Now bringing in the dual core with hyper threading. Next will be the quad core for sure. ;)

Can't make a 100 million sales objective with supply constraints on a critical component. Better to stockpile the Exynos 5 chips for the Note III.

Well, at least they will surely have more than enough of these chips for the Note 3.
And with a 3500mah of stock battery I'm pretty sure it will be clocked at 1.8-2.0ghz.
At 2Ghz, it will probably be about as powerful as SD800 although early suspicions about the Adreno 330 indicate a superior GPU

I'm getting one of these beauties, Qualcomm or Octa, doesn't matter. The white one comes home the minute AT&T rings it up. Already got a buyer for my note 2.

I'm opting for the Octa version to run on T-Mo LTE. I may not get it the day it comes out like I did with my S3, but I'll definitely be happy once I do get it.

How's AT&T where you're at?

Honestly smurf AT&T has come from horrible to very good out here in vegas. Very few dropped calls now, and great LTE coverage pretty much all over. How bout T-Mobile in your neck of the woods?

This is a well written article and I encourage all the writers of PA to do the same. I bet this article wouldn't annoy you if it was about nokia, right?!
Anyway, if you're not happy with the articles here, then GTFO you nokia troll!
