Generational gains and lossesĮlsewhere, there are a few downgrades. It’s also key to NVIDIA’s claims of 275 TOPS compute performance: While, yes, the AGX Orin can hit 275 TOPS of INT8 compute across all its cores and accelerators, it can only do so on sparse networks on a standard dense network, as compatible with the previous-generation AGX Xavier, its throughput is lower at 138 TOPS - still an impressive uplift on the 32 TOPS of its predecessor, of course. There are two models of AGX Orin modules so-far confirmed, both launching later this year: a version with 32GB of RAM, which has eight CPU cores, 1,792 CUDA cores, 56 Tensor cores, and lower maximum GPU and NVDLA frequencies and a 64GB model that has 12 CPU cores, 2,048 CUDA cores, and 64 Tensor cores plus higher maximum clock speeds.Ī big feature of the new Ampere GPU architecture is its support for sparse networks, offering a big speed bump where applicable. Hybrid moduleĪnother thing developers need to keep in mind is that the system-on-module driving the Developer’s Kit doesn’t actually exist - at least, not as a stock-keeping unit you could slot into a finished design. The fan itself is speed-controlled according to temperature, and reasonably quiet for the amount of air it pushes at around 50dBA measured at arm’s length. The full-size PCI Express slot is now protected via a removable cover, albeit one tethered to the rest of the case by cables for a pair of adhesive antennas stuck on the inside, and there’s a clearer path for the on-board fan to pull air in and push it over the heatsink. While clearly an evolution of the one included with the AGX Xavier kit, the AGX Orin case is a big upgrade. Even at idle the Jetson AGX Orin is a hungry beast, drawing 22W in MAXN mode and over 19W even when configured for the lowest “15W” setting - though NVIDIA says this will be resolved in a future software update, enabling currently-disabled power saving features to reduce idle draw to under 5W.Īll that power has to go somewhere, and that’s into a heatsink that forms part of the bundled and pre-installed case. The company’s claimed 60W draw in “MAXN” mode, which activates all CPU and GPU cores and removes any clock restrictions in place, is the widest of the mark at 98W when measured at the wall - a measurement which, in NVIDIA's defense, includes the inefficiency of the supplied USB power brick and overhead for the carrier board. The AGX Orin, by contrast, has 15W as its absolute minimal power envelope - and hikes the upper end to 60W, twice that of its predecessor.Īs with NVIDIA’s previous Jetson kits, the claimed power envelopes are measured purely at the system-on-chip - and are noticeably conservative as a result. The Jetson AGX Xavier could be configured for a 10W to a 30W target power envelope, disabling various cores to reduce power requirements as you walked down to the bare minimum. On the topic of power draw, the new Ampere GPU in the AGX Orin definitely lives up to its name. As with its predecessor, the AGX Xavier, there’s plenty of room for expansion including a full-size PCI Express slot - though depending on what you plug into it, you’ll likely need to swap out the bundled power supply for something with a little more headroom. On paper, the Jetson AGX Orin is an absolute beast - yet sits in a tiny 4.3×4.3" footprint, if you exclude the surprisingly hefty 90W USB PD external power supply bundled in the box.
