Carton RougeRed card: change of chip for the Galaxy S II

This week, it is Samsung who receives our red card. Indeed, it was discovered that since the beginning of the year two versions of its smartphone features, the Galaxy S II, are delivered. One - that known previously - equipped with one SoC Samsung Exynos 4210, the other with a Texas Instruments OMAP 4430 SoC. In his commercial brochures and on its Internet site, Samsung does nowhere this change which is simply noted on the reference of phones, than the version with TI OMAP ending with a G. Therefore, it is extremely difficult for the consumer to know what version it is buying, especially that rare are the shops to indicate the accurate and complete product reference.

For Samsung, there is not what shout to the scandal, because these two chips are timed at 1.2 GHz and "provide similar performance" according to the constructor. However, if this is more or less the case on the CPU side, it is not on the graphic part of the SoC Samsung Exynos (Mali 400 PM) being much faster than the PowerVR SGX540 of the Texas Instruments OMAP. So in the games, this can make a difference. And under Ice Cream Sandwich also, Android 4 (whose arrival on Galaxy S II has been validated by Samsung this week) using hardware acceleration on many levels. And even if early returns suggest autonomy a little better for the Galaxy S II under OMAP, it can be concluded that they are ill-informed customers who are adversely affected. Because Samsung should have play cards on the table and clear the change of chip in some versions of his phone. The manufacturer is more customary because, since there has already been slabs changes made in any discretion on some of its televisions. Regrettable and really préjuciable.
