2022: Jetson Orin Nano Announcement

On September 21, 2022, it became known that Nvidia had announced a tiny single-board Jetson Orin Nano computer. This is the evolution of the Jetson Nano more than three years ago.

As reported, there is a performance gap between the Jetson Orin Nano and its predecessor. According to the Liliputing portal, this computer turned out to be 80 times more powerful than the previous one.

This is confirmed by the measurements of Nvidia itself. If the original Jetson Nano, which was released in March 2019, gave 472 GFLOPS in applications that use artificial intelligence, then the modern Jetson Orin Nano is designed for 4x1012 trillion operations per second (40 trillion, TOPS). The developers do not give the value in gigaflops and teraflops.

But there is an important nuance here. 40 TOPS is an indicator of the older version, and there is also the younger with a result of 20 TOPS. It is 40 times more productive than the Jetson Nano.

Jetson Orin Nano showed an increase not only in its computing power, but also in the recommended price. The basic modification costs $199 (12.1 thousand rubles at the Central Bank rate as of September 21, 2022), and the eldest - $299 (18.2 thousand rubles). For the usual Jetson Nano of March 2019, Nvidia asked for only $99 or 6,000 rubles at the start of sales.

The 80x performance gain did not affect the physical dimensions of the Jetson Orin Nano. This is still only one 70x45 mm board with a SODIMM connector, like the previous Jetson Nano. In other words, it's still smaller than a regular credit card, which measures 86x54mm.

Direct competitor Jetson Orin Nano in the person of Raspberry Pi 4 Model B costs $55 (3350 rubles) for the version with 4 GB and (4570 rubles) for 8 GB. At the same time, its dimensions are 88x59x20 mm.

The Nvidia single-board is built on the basis of a chip-based system, which primarily contains six ARM cores Cortex-A78AE at a frequency of up to 1.5 GHz. The video subsystem of the chip received 512 CUDA cores in the database and 1024 in the top and a frequency of 625 MHz. It also has 16 or 32 tensor cores depending on the version chosen.

The computer does not have built-in memory - it works with external NVMe chips. As for the RAM, in both versions it is LPDDR5, but buyers of Jetson Orin Nano for $199 will receive only 4 GB with a 64-bit bus. If you give all $299 for a PC, then the amount of RAM will grow to 8 GB, and the bus - to 128 bits.

Power consumption depends on loads. The $199 Jetson Orin Nano needs 5-10 watts and $299 needs 7-15 watts. The I/O pin set includes 3xUART, 2xSPI, 2xI2S, 4xI2C, CAN, DMIC, DSPK, PWM, and GPIO.

Nvidia achieved higher processing power corny by using more modern components in the Jetson Orin Nano compared to the usual Jetson Nano almost four years ago.

For example, the Jetson Nano, with which Nvidia compares its creation, comes with 4GB of RAM of the obsolete LPDDR4 standard and a Maxwell processor against the more modern Ampere in the Jetson Orin Nano CPU. It includes four Cortex A57 cores at a frequency of up to 1.43 GHz and only 128 CUDA cores as part of an integrated graphics solution.

The features of the Jetson Nano include only the presence of a standard 16 GB eMMS 5.1 storage^[1].
