Very impressive, but it feels expensive to me. I'm cheap though.
The linked article was pretty light on the detail, and weirdly written. It never states how many cores the CPU has; I had to check Nvidia's page (http://www.nvidia.com/object/jetson-tx1-dev-kit.html http://www.nvidia.com/object/jetson-tx1-dev-kit.html) to find out: it's a quad-core so four cores.
Some pretty nice low-level embedded-style I/O on there too (GPIOs, I2C, I2S, SPI, TTL UART).
- rwmj 11y agoAccording to Wikipedia it's 8 cores (big.LITTLE, so depending on the kernel and microarchitecture they might not all be usable at the same time): https://en.wikipedia.org/wiki/Tegra#Tegra_X1 https://en.wikipedia.org/wiki/Tegra#Tegra_X1
- unwind 11y agoRight ... that's weird, why isn't Nvidia's own Jetson-page more clear on this? Confusing.
- rockdoe 11y ago~~You only get 4 usable at any given time. Either the big core runs (A57) or the LITTLE core (A53) runs.~~ Sounds like I'm mistaken.
- Narishma 11y agoIs this specific to Nvidia chips? Because that's not how it works on big.LITTLE SoCs from other manufacturers. In those you can use all cores at the same time if you want to.
- rwmj 11y agoSamsung 5410 worked like that, but apparently that was a bug in that SoC (fixed in the 5420 so you can use all 8 cores).
- paulmd 11y agoIt's basically a stock Tegra X1 SoC built out into a single-board computer. so it's best to just look and see what has been previously written about the X1. As such, I don't understand the embargo on performance measurements - barring any major surprises, I think Tegra X1's performance is pretty much known at this point. The X1 has actually got 4xA53 and 4xA57 cores in a big.LITTLE style arrangement.
