alt Hacker NewsThe X280 is nothing special as a CPU core. It's basically the U74 with added 512 bit vector unit (but only 256 bit ALU), which makes it pretty much equivalent to SpacemiT's X60 core in their K1/M1 SoCs.
There is no X280 hardware available yet for general purchase. There is the HiFive Xara X280 announced in May, but that is believed to be available to SiFive licensees only. The SG2380 was going to have X280s as an NPU alongside P670 main cores, but that's been cancelled as a result of US sanctions on Sophgo. The PIC64-HSPC is a rad-hard chip using the X280 for NASA and other space customers, but will not be cheap -- the RAD750 PowerPC chip it is replacing reportedly costs $200,000 each.
Indeed, the U.S. Government $8.9 billion investment in Intel common stock could be an indication the entire force of the political structure may drop a boot on competitors.
Regulatory capture is something people need to take seriously. Some may shelve product IP for a few years, or set-up parallel factories in other countries without the artificial trade/global-talent barriers.
A standard doesn't have to be perfect, but must be consistent over significant periods of time to matter. Consider what happened to OpenSparc, Cell, IA-64, dojo tiles, and early RISC (Windows NT prototype was ported off by Microsoft.)
The NVIDIA CUDA card kludge wasn't necessarily "better" than something like the M3/M4/M5 at every task. But was economical hardware due to volume pricing, has 92% of the ecosystem, and most software already worked given it isn't walled-off.
Note people tend to avoid buying work, or porting to short-lived hardware. Best of luck, =3
