Microsoft has introduced hardware-accelerated BitLocker encryption in Windows 11 to improve performance and efficiency by offloading encryption tasks to a dedicated cryptography accelerator in future CPUs. This new technology aims to reverse the performance penalties caused by software-based encryption, offering up to twice the storage performance in certain workloads. The company plans to implement this new hardware-accelerated BitLocker on upcoming Intel Core Ultra series 3 "Panther Lake" CPUs, with broader support expected in the future. This update is expected to significantly enhance storage and I/O metrics, reduce CPU cycles by up to 70%, and improve battery life for users.

New cost-effective DDR5 memory 'HUDIMMs' show around 50% reduction in throughput with single subchannel — Two HUDIMMs are as fast as a single stick of regular DDR5 RAM

New cost-effective DDR5 memory 'HUDIMMs' show around 50% reduction in throughput with single subchannel — Two HUDIMMs are as fast as a single stick of regular DDR5 RAM

The article discusses the introduction of cost-effective DDR5 memory called "HUDIMMs," which utilize a single 32-bit subchannel instead of the traditional 64-bit wide bus. Testing conducted by HKEPC and Asus revealed that HUDIMMs experience a nearly 50% reduction in bandwidth, significantly impacting performance. By simulating HUDIMM on standard DDR5 RAM, the study demonstrated a notable decrease in read, write, and copy speeds compared to regular DDR5 RAM. While HUDIMMs offer cheaper alternatives with fewer ICs per stick, the trade-off is a substantial performance hit, especially in dual-channel setups. Additionally, the article mentions the potential performance benefits of combining HUDIMM with regular DDR5 in asymmetric dual channel support configurations.

Original Task Manager creator explains why it lies to you about CPU usage — former Microsoft engineer shows unique solution to a seemingly simple, but actually complicated, task

Original Task Manager creator explains why it lies to you about CPU usage — former Microsoft engineer shows unique solution to a seemingly simple, but actually complicated, task

Former Microsoft engineer Dave Plummer, creator of the original Task Manager, explains the complexity behind measuring CPU usage accurately. Plummer reveals that the Task Manager provides an interpretation of CPU usage between refreshes, not a real-time view. He details a unique solution where the tool calculates CPU consumption based on total time and processes, offering a more precise measurement. However, with modern processors' dynamic behaviors, the traditional method may feel less accurate due to factors like frequency scaling and thermal throttling. Plummer suggests a new approach where CPU usage reflects work accomplished compared to potential work, but acknowledges his retirement from Microsoft limits his influence on future developments.
