With the launch the Samsung Galaxy S6 and S6 Edge last month, Korean manufacturer Samsung managed to gain some serious design and performance wins over its competitors, theoretically or otherwise. While some GPU benches put the performance of the Galaxy S6 duo to be behind that of Apple’s iPhone 6, owing primarily to the screen’s 2K resolution, that doesn’t mean the Galaxy S6 pair is behind in every other aspect as well. Folks over at Chipworks have carried out their first teardown of the Samsung Galaxy S6, so lets take a look at what Samsung’s flagship is made of. Literally.

Samsung Galaxy S6 Teardown Reveals A Host Of Homemade Components Under The Hood

While the Exynos 7420 has gotten the most attention at being Samsung’s homemade component inside both the Galaxy S6 flagships launched this year, its by far the only one. While we’ll be getting into the 7420 later on, Chipworks has managed to identify a host of other components inside the Galaxy S6 that bear Samsung’s name. These range from the LPDDR4 memory on the device to its modem and the image processor and include Power Management ICs and a NFC controller to name a few.

While we all know that the Exynos 7420 powering the Galaxy S6 is the first of its kind, having been manufactured by the South Korean electronics giant on its 14nm finFET, its the die size of the the chip that’s turned out to be quite spectacular indeed. Samsung’s die size for the Exynos 7420 is 78 mm2, which when compared to the 118m2 on the Galaxy S5’s Snapdragon is quite a reduction indeed. Even though the latest 14nm process does reduce die size, such a reduction is highly unlikely to be completely because of a new manufacturing process.

Also, looking at the processor packaging for the Exynos 7420, its not clear whether Samsung’s chosen to manufacture the Exynos 7420 in the device taken apart at its own plants or at the ones owned by its partner, Globalfoundries. But that’s only a tiny bit of mystery. We’ll be posting more reviews of the Galaxy S6 and S6 Edge in the future so make sure to keep checking.
