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.
