Last week I provided a look at the Intel Xeon 600 series Hyper Threading performance with the Xeon 678X "Granite Rapids WS" processor for HT/SMT on and off. That was interesting while another reader request was to look at the CPU core scaling performance for this high-end workstation processor. Here are those benchmarks for showing the performance, power, and frequency/thermal impact of the Xeon 678X when limited to 6 cores, 12 cores, 24 cores, 48 cores, and then the 48 cores + HT default configuration.

AMD's compiler team is proposing a new LLVM Clang compiler option, -fenable-readonly-thp for implementing instruction Transparent Huge Pages "iTHP" at compile and link-time. With -fenable-readonly-thp, they are finding more performance out of SPEC CPU, Geekbench, and other workloads from the arranging of 2MB segment alignment at link time and allowing the executable text range can be promoted to huge pages...

Earlier this month when benchmarking six Linux distributions on the new Framework Laptop 13 Pro powered by Intel Core Ultra Series 3 "Panther Lake", the performance was strangely slow on Fedora Workstation 44. When digging further into it, the performance loss was with Fedora 44 using Tuned-PPD by default where as other Linux distributions default to Power Profiles Daemon. Ultimately, after Red Hat engineers got involved, was found to be a bug within the Intel P-State kernel driver exhibited by Tuned-PPD. The latest Linux kernel already has a fix in place and will be back-ported to Fedora 44...
