Samsung SoC chaos

Read it here.

It seems that the change to Snapdragon on the S4 was a last minute decision.

Something went on during last winter that panicked the mobile division to change SoC provider for many variants of the S4. Mounting evidence of this can be found in the overlapping local-specific variants in the official source code of both Qualcomm and Exynos platforms. JF based variants, which are based on the Snapdragon chips, overlapped JA based variants, based on the Exynos platform. Korean (jf_ktt, jf_lgt, jf_skt <> jaltektt, jaltelgt, jalteskt), European (jf_eur <> jalte), and Japanese (jf_dcm <> jaltedcm) variants were developed for both platforms. The Korean variants ended up being the sole ones to actually hit the market with the Exynos platform, other than the global 3G version of which there’s no evident Qualcomm counterpart.

They probably realized that they can't make enough Exoynos SoCs for the Europe and NA market, so they went with Qualcomm, who can provide them with as many chips as they need.

this. They realized they couldn't crank out enough Exynos SOCs without delaying their release date.

Honestly, all things considered the snapdragon version is the better all around product of the two. The exynos quad has some pretty big issues regarding the core switching.

samsung is almost new to this thing so it was obvious that they'd face these problems. snapdragon processors are awesome and i'm feeling even happier after reading that the note 3 will use the snapdragon 800 processor clocked at 2.3 GHz, where as the exynos octa chip has a max speed of 2 GHz. will definitely plan to buy the note 3.

well, they couldn't manufacture huge amounts of the exynos octa core chip, so they decided to introduce 2 versions, one with the snapdragon 600 processor(70% S4s use this) and the other one with the exynos octa core chip(which powers only 30% of the S4s). but, in my opinion the exynos variant is better, too bad it wasn't available in my country.

Why are they new to this? Samsung is an engineering powerhouse. They just can't crack out enough Exynos SoCs.

Even various Note 2/S3/S2s had Exynos processors over the years.

Samsung has a long history of producing chipsets that predates the Exynos line. I believe the iPhone 3GS uses a Samsung chipset, just not branded Exynos.

Don't forget about all the different bands and markets. Snapdragon ownes the lte rights and samsung would need to add a separate modem for ever exynos soc. The snapdragon has the modem built in and already supports all the base bands.

The korean shve300 exynos 5 gs4 supports lte but none that the usa market uses and would need a different modem to support our market bands.

The Korean variant of the Exynos supports 20 LTE bands, including band 17 that AT&T and T-Mobile use.

The Note 2 came here with an Exynos SoC. I'm fairly certain it had no Qualcomm radio in it.

It supports all bands of LTE worldwide.

It will NOT work in the usa they are hardlocked out and that phone has a seperate qualcomm modem in it.im not saying there is no support by the actual modem im saying samsung did not pay to license it and the note 2 has a separate modem added to it that is not built into the main exynos soc

and what do you mean? Qualcomm owns 4g and sells all the modems that use it.even the iphone 5 has a qualcomm modem in it

You do realize that Samsung has building ARM SoC's for a very long time, for 13 years in fact. Every single iPhone, iPad and iPod touch released so far has included an SoC which has been made by Samsung. So how come they are now to this?

The real issue is Samsung refuses to release the Exynos 5 source code. Oh, how I hate them right now.

Well for the octacore that is. The Nexus 10 has full support for its exynos 5250. If you want aosp for a galaxy phone buy the snapdragon version.

Mind the bump but news about a new Exynos 5 variant had surfaced. Apparently, the Exynos 5410 is rife with heating issues.
Link.

Will they abandon the big.LITTLE architecture and go for quad Cortex-A15s?
