Windows Server 2025 now supports native NVMe I/O, offering significant performance gains with up to 80% higher IOPS and 45% lower CPU utilization under high I/O loads. This update eliminates SCSI emulation limitations, providing a boost for scenarios like high-performance file serving, virtualization, AI/ML workloads, and databases. Microsoft's engineering team redesigned the I/O processing workflow for extreme performance, resulting in improved latency and round-trip times. While the feature is currently available in Windows Server 2025, its arrival in Windows 11 remains uncertain due to potential compatibility issues with consumer-grade drives.

Intel's upcoming Xeon 7 "Diamond Rapids" server CPUs reportedly delayed to 2027 — Next-gen Coral Rapids lineup lands 2028 but can be accelerated, according to new leak

Intel's Xeon 7 "Diamond Rapids" server CPUs have been delayed to 2027, with the 8-channel variant canceled in favor of focusing on 16-channel SKUs. The lineup will feature up to 256 cores initially, with a 512-core version to follow shortly after. Diamond Rapids will lack hyperthreading support, unlike the next-gen Coral Rapids lineup, which is expected to launch in mid-2028 with 8-channel variants. Intel may accelerate the rollout of Coral Rapids based on market demand. AMD's EPYC Venice CPUs are still on track for a 2026 release.

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.
