Nvidia Tegra 4 to Feature 4 Cortex A15 Cores, 72 Graphics Cores

December 19th, 2012 Leave a comment Go to comments

According to Nvidia Tegra roadmap, the first Tegra 4 (T40) is due in Q1 2013, before T43 & AP40 come out in Q3 2013. Information is still sparse, but somebody posted a leaked slide on Chip Hell which gives a few more details about the upcoming Tegra 4 processors.

So this is what we currently know about the Tegra T40 processor:

  • CPU – 4x Cortex A15 (Eagle) cores @ 1.8 GHz + a battery saving core (aka companion core).
  • GPU – Geforce GPU with 72 cores providing 20x Tegra 2 performance and 6x Tegra 3’s.
  • Memory – Support for DDR3L, LPDDR2 and LPDDR3
  • Video – 1440p video encoding and decoding with VP8 and H.264 High Profile hardware acceleration
  • Display –  2560×1600 24-bit, 1080p @ 120Hz, 4K displays via DSI and HDMI interfaces.
  • Power – Lower power than previous generations thanks to 28nm HPL process (low power with high-k metal gates). Tegra 4 will also feature a 5th core and PRISM (Pixel Rendering Intensity and Saturation Management) to optimize low power consumption.
  • I/O – USB 3.0, and… ?

Nvidia Tegra 4 will also feature hardware accelerated security for HDCP, secure boot and DRM. Nvidia T40 will be used in high-end tablets, smartphones and clamshell devices. We may know more about the processor, and possibly see some prototypes at CES 2013.

    ARMv7 is not the Cortex A15 commands set for default… maybe its not 64 processor?

    It’s not a 64-bit processor. The only announced ARM cores with 64-bit instructions set are Cortex A53 and A57 (armv8).
    Cortex A15 still uses ARMv7 instructions set, maybe with some extensions, I’m not sure about the details.

    Yes, Cortex A15 uses ARMv7-A (like Cortex A9) with some extra instructions: http://www.arm.com/products/processors/cortex-a/cortex-a15.php
