A common software technique to implement nearly quadruple precision using pairs of double-precision values is sometimes called double-double arithmetic.
Using pairs of IEEE double-precision values with 53-bit significands, double-double arithmetic provides operations on numbers with significands of at least[4] 2 × 53 = 106 bits (...), only slightly less precise than the 113-bit significand of IEEE binary128 quadruple precision.
The Raspberry Pi Foundation simply changed the bootloader code to enable the Network install feature, and yes, it will only work with Raspberry Pi 4, CM4, and Raspberry Pi 400 keyboard PC, but not Raspberry Pi 3 and earlier models.
Using a Raspberry Pi 400 keyboard computer with 4GB of RAM, I ran some fresh benchmarks of Raspberry Pi OS in its default 32-bit build and then again with the new 64-bit build.
Across the few dozen different workloads tested, switching Raspberry Pi OS 11 for the 64-bit version improved the performance on average by about 48%. See all the 32-bit vs. 64-bit Raspberry Pi benchmarks over on OpenBenchmarking.org.
The 64-bit version of Chromium, installed by default, has no version of the WidevineCDM library and therefore, it is not possible to play streaming media such as Netflix or Disney+.
