#About Tegra K1
Tegra K1 is NVIDIA's first mobile processor to have the same advanced features & architecture as a modern desktop GPU while still using the low power draw of a mobile chip. Therefore Tegra K1 allows embedded devices to use the exact same CUDA code that would also run on a desktop GPU (used by over 100,000 developers), with similar levels of GPU-accelerated performance as a desktop.
#About Jetson TK1
Jetson TK1 dev board Jetson TK1 is NVIDIA's embedded Linux development platform featuring a Tegra K1 SOC (CPU+GPU+ISP in a single chip), selling for $192 USD. Jetson TK1 comes pre-installed with Linux4Tegra OS (basically Ubuntu 14.04 with pre-configured drivers). There is also some official support for running other distributions using the mainline kernel.
Besides the quad-core 2.3GHz ARM Cortex-A15 CPU and the revolutionary Tegra K1 GPU, the Jetson TK1 board includes similar features as a Raspberry Pi but also some PC-oriented features such as SATA, mini-PCIe and a fan to allow continuous operation under heavy workloads:
Hardware Features Dimensions: 5" x 5" (127mm x 127mm) board Tegra K1 SOC (CPU+GPU+ISP in a single chip, with typical power consumption between 1 to 5 Watts): GPU: NVIDIA Kepler "GK20a" GPU with 192 SM3.2 CUDA cores (upto 326 GFLOPS) CPU: NVIDIA "4-Plus-1" 2.32GHz ARM quad-core Cortex-A15 CPU with Cortex-A15 battery-saving shadow-core DRAM: 2GB DDR3L 933MHz EMC x16 using 64-bit data width Storage: 16GB fast eMMC 4.51 (routed to SDMMC4) mini-PCIe: a half-height single-lane PEX slot (such as for Wifi, SSD RAID, FireWire or Ethernet addon cards) SD/MMC card: a full-size slot (routed to SDMMC3) USB 3.0: a full-size Type-A female socket USB 2.0: a micro-AB female socket (for connecting to a PC, but can also be used as a spare USB 2.0 port using a micro-B male to female Type-A adapter that is sometimes included) HDMI: a full-size port RS232: a full-size DB9 serial port (routed to UART4) Audio: an ALC5639 Realtek HD Audio codec with Mic in and Line out jacks (routed to DAP2) Ethernet: a RTL8111GS Realtek 10/100/1000Base-T Gigabit LAN port using PEX SATA: a full-size port that supports 2.5" and 3.5" disks, but is not hot-pluggable. (Turn off the power before plugging in SATA disk drives) JTAG: a 2x10-pin 0.1" port for professional debugging Power: a 12V DC barrel power jack and a 4-pin PC IDE power connector, using AS3722 PMIC Fan: a fan-heatsink running on 12V (to allow safely running intense workloads continuously, but can usually be replaced by a heat-spreader or heatsink) The following signals are available through the 125-pin 2mm-pitch expansion port:
Camera ports: 2 fast CSI-2 MIPI camera ports (one 4-lane and one 1-lane) LCD port: LVDS and eDP Display Panel Touchscreen ports: Touch SPI 1 x 4-lane + 1 x 1-lane CSI-2 UART HSIC I2C: 3 ports GPIO: 7 x GPIO pins (1.8V). Camera CSI pins can also be used for extra GPIO if you don't use both cameras. Front panel connector:
