    What is holdup with Samsung Exynos 5 Octa? (Only 30% of S4 will be powered by the Exynos Octa(

    Why the Exynos 5 Octa chip so scarce?

    "What's the holdup? Well, it turns out that Samsung went with the simpler and cheaper way to design 28nm chips like the Exynos 5 Octa, called gate-first, while the competing foundry TSMC designed its production capacity with the harder to implement gate-last process, developed by Intel. The problem stems from the fact that gate-first might be easier to transition to, but gives yield problems later on, especially with complex SoCs, and that's exactly what seems to be happening with Exynos 5 Octa.

    TSMC (where all NVDA's parts are fabricated) started the 28nm with gate-first HKMG, but transitioned successfully to the gate-last process by the end of 2012 according to SemiWiKi:

    • And normally in Technology, Yield problems goes hand in hand with RELIABILITY problems. I would not touch an Octa phone from Samsung until they change the process.

      Not surprised it's sold in mostlty 3rd world countries as an insurance against liabilities.

    • " It was announced at the CES expo back in January, at a presentation, which, while not an off-Broadway show like the S4 unveiling, was pretty high up their in visuals and celebs, and where even former President Bill Clinton took the stage to endorse Samsung's efforts in making the world a better place, one gadget at a time."

      Too bad Nvidia didn't get a piece of the action. Tegra 4 was announced at the same time as Samsung's chip.
