    The A15 is a Powerhog. Even Nvidia is going with A9 tegra4i instead of tegra4

    which is based on A15.

    I doubt you'll find many people using the A15. Apple and Qualcomm have their own designs.

    ARM is so over... Will NEVER be able to compete against Intel's offerings in Power and Performance. Even the Apple and Qualcomm designs are severly limited.

    • Yep, the dirty little secret is that the A15 at 28nm uses way too much power for a phone. At 2ghz, a QC can use to 5-10W with graphics thrown into the mix. OTOH, it is a lot more powerful than a dual core Atom, so it will definitely run a laptop well.

    • The Tegra 4's first design win:

      Mobes with monster 72-core GPU to debut in China
      ZTE says handsets packing Tegra 4 system-on-chip will land before July
      By Phil Muncaster, 21st February 2013

      Nvidia’s supercharged quad-core Tegra 4 SoC, which packs a mighty 72 GPU cores, has finally found a mobile home after handset maker ZTE announced new smartphones featuring the chip will debut in China in the first half of 2013.

      The Tegra 4 was unveiled last month at CES but has so far been left to stand at the altar by the smartphone makers, like the intimidatingly powerful bride it is.

      That’s set to change now and could bring smartphone users significant leaps in graphics capability courtesy of those 72 custom GeForce cores. This will obviously make for smoother, more realistic gaming on the mobile but also, as The Reg pointed out at CES, improved photos with High Dynamic Range (HDR) imaging support.

      The quad-core ARM Cortex-A15 CPU is not a huge performance leap up from Tegra 3 by comparison but the SoC apparently manages to consume 45 per cent less power than its predecessor, thanks in part to a “second-generation battery-saver core”.

      As per Tegra 3, this extra (fifth) CPU core runs the phone during normal operation, allowing the A15s to take over when some serious processing power is needed.

      Improved web browsing and app download times are also promised by Nvidia.

      There’s no detail yet on which handset models will sport the new chips, although one of them will be an LTE version featuring Nvidia’s i500 chipset, ZTE said. That chipset has been crammed inside a new smaller SoC, the 4i, which was announced on Tuesday.

      Nvidia explains its performance efficiency benefits and why the i500 is likely to be around for a while to come, in a blog post here.

      Sadly ZTE was unable to confirm if or when the upcoming Tegra 4 handsets would make it out of the People’s Republic.

      Nvidia isn’t the only chip firm looking to set its stall out ahead of MWC next week, however. STEricsson announced on Wednesday what it claims to be the world’s fastest smartphone processor – the gargantuan 3Ghz NovaThor L8580.

      The 28nm, Cortex-A9 chip is being touted by ST as a disruptor in the wireless space, although it remains a prototype so won’t be in devices for some time yet

      • Wow, Nvidia's Tegra 4 has a design win. Clearly they didn't read Charlie's article before they made their commitment. The design wins need to be in the 20s to 30s. They have one. Not especially a fan of Charlie but it looks like he got this one right.

        "The Tegra 4 was unveiled last month at CES but has so far been left to stand at the altar by the smartphone makers."

        This Charlie says is because they have burned the OEMs consistently in the past with false promises...

        Sentiment: Strong Buy

    • Did TI find a buyer for its OMAP A 15 design ?
      not to my knowledge

    • STUPID !!!!!

        Rumor: Galaxy S4 to be powered by Qualcomm chip, no Exynos version. But is that possible?

        by Bogdan Petrovan on Feb 20, 2013

        "If a report from the Korean site Digital Times is accurate, 2013 will be the first year when Samsung will not release an Exynos-powered Galaxy S. Why is that? According to DT, Samsung was forced to scrap the plans of using an Exynos 5 Octa chip in the Galaxy S4 due to issues with excessive heat generation and power consumption. "

        Are you say Samsung is stupid?
