We still don't know what's going to happen for Bcachefs in the Linux 6.17 kernel even with the merge window set to end on Sunday with the Linux 6.17-rc1 release. Linus Torvalds commented over one month ago that they would be parting ways for Linux 6.17.

DDR5-6400 vs. DDR5-4800 R-DIMM Performance For Threadripper 9980X / 9970X CPUs

Phoronix - Fri, 08/08/2025 - 22:40
Last week the Threadripper 9000 series began shipping and as shown in our launch-day Linux testing there was stunning performance with the 32-core Threadripper 9970X and 64-core Threadripper 9980X processors. Beyond the improvements thanks to the Zen 5 microarchitecture enhancements, the new Threadrippers while working as a drop-in replacement to existing TRX50 workstation motherboards now can handle DDR5-6400 R-DIMMs up from DDR5-4800 R-DIMMs with the Threadripper 7000 series. For those wondering about the gain attributed to the faster memory modules, here are benchmarks looking at the DDR5-4800 vs. DDR5-6400 real-world performance impact for AMD Ryzen Threadripper 9970X and 9980X CPUs.
