The Samsung Exynos 5 Octa processor may be a headline grabber for its eight-core design, but in reality Samsung's own chip will only be present in around 30% of the first 10 million Galaxy S4s sold around the world.
The majority will instead come equipped with the quad-core Snapdragon 600 processor, albeit one clocked at a speedy 1.9GHz, with Samsung reportedly having struggled to get enough of its eight-core beast produced in time.
Korea's ETNews tells us Samsung has faced various production and performance issues with the Exynos 5 CPU, and production volumes will only hit 100% sometime in Q2, which is too late for the first wave of Galaxy S4 shipments.
With Samsung expecting to sell 40 million Galaxy S4s in the first three months after launch, there's clearly been a bit of a reshuffle. Things are simple enough in markets supporting 4G networks, as the Exynos 5 isn't LTE-capable.
But even in 3G-only territories, and on 3G networks in 4G-supporting countries such as the UK, Samsung is clearly leaning heavily on the Snapdragon 600 until it can get production of its own next-gen processor fully up to speed.
