Supposedly happened earlier this year. Tenstorrent says devboards in Q3.
Now we just wait.
That's useable for many applications, but it's not going to change the world. A lot of "micro PCs" with low power CPUs are well past that now. If that's what Ascalon turns out to be, it will amount to an SBC class device.
The Raspberry Pi 5 results on Geekbench 6 are all over the place. A score between 500 to 900 in single core and a 2000 multi core score.
Radxa 4 is an SBC based around the N100 and it basically gets the same or slightly higher performance as the Raspberry Pi 5.
Meanwhile the i5-9600K gets a score of 1677 in single core, which is 83% of the performance of the entire Raspberry Pi 5 and gets a score of 6199 when using multiple cores, that's 3x the performance.
I'd call this at least "Laptop class" and you even admitted yourself back in 2025 that you're using a processor on that level.
My bubble includes a number of SBCs and embedded boards from Advantech, most with Ryzen embedded (V1000 class) CPUs.
SBC is too vague I suppose. Past the hobbyist level of SBC, there are many* vendors with Core i5-1340P and similar CPUs today. These are superior to a 2018 i5-9600k. That's a 2023 device, which aligns with what I concluded at the time.
In 2025+, such a CPU is not a desktop class device, and is sufficient in a modest laptop in lower power form. I use one for light Linux development work.
* LattePanda Sigma, ASROCK NUC, DFROBOT, Premio and many NAS and industrial devices.
BTW. Keller is also on the board for AheadComputing — founded by former Intel engineers that had been behind the fabled "Royal Core".
