Silly Engadget. We don't know if the US, specifically Sprint model, will get the Exynos or S4. If S4, it'll be more like EL TEvo than not. If Exynos, this new Exynos 4412 has a twist to it that we've not seen before - the cores run asynchronously for clock speed and voltage levels - just like the S4. I'm just about positive that's a first for an ARM Cortex cpu design. Translation - anything up to two cores used, the S4 will win. If more cores are used, the Exynos could match the S4 or pull out ahead. The S4 is built using the power-friendly (more like get you drunk and seduce you than friendly) 28 nm manufacturing process. The Exynos is built from a 32 nm process. The processors are going to be close (with the nod probably going to Exynos for very heavy gaming).
