Administrator DKT27 Posted December 19, 2012 Administrator Share Posted December 19, 2012 Details of Nvidia’s upcoming Tegra 4 SoC, due early next year, have leaked. If the leak is to be believed, Tegra 4 (codename Wayne) will be a quad-core Cortex-A15 (with a fifth, low-power companion core), with a 72-core GPU — six times more than Tegra 3. At this point we should stress that this leak might not be real, though the specs dovetail quite neatly with what we already knew. The shift from Cortex-A9 to A15 will bring Tegra 4 in line with the latest Snapdragon S4 and Exynos 5 SoCs. The jump to 72 cores (from Tegra 3′s 12) might sound dramatic, but it’s important to note that the Tegra 3′s graphics performance pales in comparison to Apple’s latest A5X and A6 SoCs. Of course, if Nvidia also changes the architecture of those 72 cores — to something resembling Kepler — then Tegra 4 will be a complete beast. It is odd (and a little unnerving) that the GPU’s underlying architecture isn’t listed on the leaked diagram. Drilling down into the CPU, the leak says that Tegra 4 features a “4-PLUS-1 Quad Core Eagle.” Eagle was the codename for Cortex-A15. 4-PLUS-1 is Nvidia’s obnoxious trademark on a quad-core design, with a low-power companion core that takes care of smaller, background tasks. It isn’t clear if the fifth core will be Cortex-A15, or a “little” Cortex-A7 core. The SoC itself will be fabricated on TSMC’s 28nm HPL (high performance, low power) process, again bringing it into line with the 28nm Snapdragon, Exynos, and A6. Rounding out the leaked specs, Tegra 4 will apparently be capable of outputting 1080p @ 120Hz, full hardware encode/decode for video up to 2560×1440 (1440p), and a maximum output resolution of 3820×2160 (4K). There’s also support for HDMI (with HDCP) and USB 3.0. Curiously, there’s no mention of integrated LTE. No LTE, coupled with the lack of info about the GPU architecture, make me a little suspicious about the veracity of this slide — or if it isn’t fake, it might just be old. Either way, we’ll find out for certain at Tegra 4′s official unveil at CES in January. :view: View: Original Article Link to comment Share on other sites More sharing options...
