Benchmarking 18 Years Of Intel Laptop CPUs: Panther Lake As Much As 95x The Speed Of Penryn

For those curious how far Intel laptop CPU performance has evolved over the past nearly two decades, here are power and performance numbers when re-benchmarking all of the Intel-powered laptop CPUs I have on hand that are still operational from Penryn to Panther Lake. A ThinkPad from 2008 with the Core 2 Duo T9300 "Penryn" was still firing up and working with the latest upstream Intel open-source Linux driver support on Ubuntu 26.04 development. On a geo mean basis over the past 18 years from Penryn to Panther Lake, the performance was at 21.5x in over 150 benchmarks. At the most extreme was a 95x difference going from Intel's 45nm Penryn to the 18A Panther Lake.

Linux 7.1 Looks To Support Extended Attributes On Sockets For New GNOME & systemd Functionality

While the Linux 7.0 feature merge window ended this past weekend and that next kernel release won't debut as stable until April, there are already features out on the horizon that are being positioned for likely merging into the Linux 7.1 kernel assuming no issues appear or objections raised by Linus Torvalds. One of the features already looking like it will be submitted for Linux 7.1 is supporting extended attributes on sockets...

b4's Review TUI With AI Integration Nearing Pre-Alpha Release

The b4 tool used for managing patch workflows to the Linux kernel has been seeing a lot of work recently on b4 review as the text user interface (TUI) to help expedite the patch review process for the Linux kernel. The b4 review TUI has been integrating AI agent code review helpers powered by the likes of Claude Code too for trying to help enhance the efficiency for Linux kernel patch reviews. That b4 review work is quickly approaching a pre-alpha state...

LLVM Clang 22 Compiler Performance Largely Unchanged Over Clang 21 On AMD Zen 5

With yesterday's stable release of the LLVM Clang 22 compiler it didn't take long for Phoronix readers to begin asking about the performance of this half-year feature update to this prominent open-source C/C++ compiler. What I am seeing so far are no big surprises with the performance largely being similar to Clang 21 across various open-source C/C++ workloads in the testing thus far. This initial round of reference benchmark results between LLVM Clang 22, Clang 21, and Clang 20 were done on an AMD EPYC Turin (Zen 5) Linux server.

AMD Announces The EPYC 8005 "Sorano" Series

The EPYC 9005 series for high-end Zen 5 server processors is a year and a half old and then at the lower-end of the spectrum is the EPYC 4005 series AM5 server processors that launched last year. On the embedded side is also the EPYC Embedded 2005 series. AMD has now filled the void between with the long-awaited EPYC 8005 series...

Arm & Linaro Launch New "CoreCollective" Consortium - With Backing From AMD & Others

The embargo just lifted on an interesting new industry consortium... CoreCollective. The CoreCollective consortium is focused on open collaboration in the Arm software ecosystem and to a large extent what Linaro has already been doing for the past decade and a half. Interestingly though with CoreCollective for open collaboration in the Arm software ecosystem, AMD is now onboard as a founding member along with various other vendors...
