Qualcomm confirmed Friday that the Samsung Galaxy S4 will come with a 1.9Ghz quad-core Snapdragon 600 processor, and it has said to Ars in an email that this particular variation of the handset will be the one that launches in the US.

Yesterday at its official event, Samsung noted that it would be launching two different versions of the Galaxy S 4: one that uses an eight-core Exynos 5 processor and one that would be fueled by a quad-core Snapdragon 600 system-on-a-chip (SoC). However, it was uncertain which variation would make it to the US.

Originally unveiled at CES, the Snapdragon 600 uses Qualcomm’s ARM-compatible Krait cores and can deliver up to 40 percent better performance than its predecessor, the Snapdragon S4 Pro, according to the company. It also includes an enhanced Adreno 320 GPU and LPDDR3 memory support. The other SOC in the mix is Samsung’s Exynos 5, which depends on ARM’s big.LITTLE technology to combine four speedy CPU cores with four slower but more power-efficient ones.

The Galaxy S 4 will join both the HTC One and LG Optimus G Pro, two other handsets that also run on Qualcomm’s Snapdragon 600.
