After arriving two weeks late, AMD's Ryzen 9000-series desktop processors disappointed some buyers and reviewers due to lackluster performance. Now, the company has addressed those issues with several new updates. The biggest speed brake for Ryzen 9000 desktop CPUs was the lack of Windows 11 branch prediction optimizations. For relief, you needed to either wait for Windows 11 24H2 (currently in the release preview channel), or add the optional KB5041587 update. However, AMD announced that the fix is now included by default in both Windows 11 version 23H2 build 22631.44112 or the latest 24H2 builds. That should boost performance by 3-13 percent across various games, with the biggest gains in Ryzen 9000 and Zen 5 processors. On top of that, AMD released the AGESA PI 1.2.0.2 BIOS update for Ryzen 5 9600X and Ryzen 9700X processors. That extends the warranty on those processors to allow for a TDP (max power) level of 105W, way up from the 65W launch TDP. That alone will boost speeds up to 10 percent on AM5 and X870 series motherboards, AMD said. It also introduced core-to-core latency optimization for Ryzen 9000 series multi-CCD (chiplet) models. Testers noticed that it sometimes took two transactions to both read and write when information was shared across cores on different CCDs. Though AMD called this a "corner case," the latest BIOS update cuts the number of transactions in half, helping latency in that scenario. "Our lab tests suggest Metro, Starfield and Borderlands 3 can show some uplift, as well as synthetic tests like 3DMark Time Spy," AMD wrote. Still on the speed theme, AMD noted that X870 and X870E motherboards are now available with support for PCIe Gen 5 graphics (i.e., the upcoming NVIDIA RTX 5000 GPUs), NVMe storage and USB4 as standard. AMD also introduced support for "enthusiast-class" DDR5-8000 EXPO memory support, with 1- to 2-nanoseconds of latency improvement. While not for everyone, "it's a great option for enthusiasts who want to push their systems to the limit," AMD said.

Buyers that paid at least $93,990 to be among the first to own (and beta test) Tesla's Cybertruck are finally getting a key, promised feature: Full Self-Driving (FSD). Several people on the Cybertruck Owners Club forum including an Angeleno who posted a video say that it has finally arrived in early access to select users, Electrek reported. After Tesla promised that FSD would arrive to Cybertrucks in September, the supervised version 12.5.5 v12 (the latest available) is shipping, but only to users in the early access program. That means the feature (included in the Tesla Cybertruck Foundation package) won't be available to most buyers for at least another month, based on Tesla's previous FSD history. FSD worked smoothly for the short amount of time it was shown, according to the video above from Cybertruck Owner's Club forum user espresso-drumbeat. It guided the vehicle through an urban area then onto a freeway ramp before arriving on the I5 toward LA, all in relatively light evening traffic. According to the update description, FSD (Supervised) v12 includes vision-based attention monitoring with sunglasses and merges city and highway into a single software stack. In other words, it's the first version to fully manage driving using end-to-end AI. Cybertruck deliveries first started 10 months ago, so FSD has been a long time coming. Recent testing by the independent automotive testing group AMCI determined that Tesla's FSD can only go 13 miles on average before requiring human intervention. Elon Musk recently promised unsupervised self-driving by the end of 2025, but he has been making that same claim for nearly 10 years and it's still not here. There's more pressure now than ever, though, as the company is set to reveal its FSD-dependent robotaxi product on October 10th.

The UK's last coal plant will sigh out its final pollutants Monday before shutting down for good and officially ending the country's century and a half of coal production. Nottinghamshire's Ratcliffe-on-Soar plant was the last of its kind following Britain's 2015 commitment to close all coal power plants by 2025. Ratcliffe was originally scheduled to shut down in 2022 but stayed open after Russia invaded Ukraine and Europe entered a gas crisis. The Ratcliffe plant once had 3,000 engineers but only employs 170 staff now. That group will gather to watch a livestream of the plant being turned off, and over 100 of them are set to work on decommissioning the plant over the next two years. Many of the other employees will enter new jobs at different power plants owned by Uniper, Raticliffe's German owner, while others will enter training programs to work on other aspects of the industry. Britain opened the world's first coal power plant in 1882, London's Holborn Viaduct, with the help of Thomas Edison's Edison Electric Light Company. Coal has played a major part in the UK until very recently. According to a report from energy think tank Ember, coal was responsible for 39 percent of the UK's energy supply in 2012 but shrunk to just two percent in 2019. The decrease in coal production was reportedly equal to double the amount of all greenhouse gases used in the UK in 2023. Between 2012 and 2023, wind and solar generation also increased from six percent to a 34 percent share of the UK's energy. Britain still has a long way to go, but this step has made it the first G7 country to remove all coal power production.This article originally appeared on Engadget at https://www.engadget.com/the-uk-says-goodbye-to-coal-production-114520865.html?src=rss
