AIDA64 vs y-cruncher

AIDA64 Extreme provides home users with detailed PC system information, live monitoring, benchmarking, and stress testing. It identifies processors, motherboards, graphics cards, memory, and storage. Other editions address business and network administration. AIDA64 Business monitors more than 250 sensor devices for temperatures, voltages, fan speeds, and power draw; it can collect hardware and software inventories from Windows computers on a corporate network. Business reports can be saved in open formats or an SQL database, and audit snapshots can be compared to identify changes and trigger real-time alerts. It also supports remote monitoring and control, including administrative tasks and file transfers. Network Audit is limited to inventory and does not include remote control, remote monitoring, diagnostics, or benchmarks available in other editions. AIDA64 supports more than 50 LCD and VFD screens, plus wireless sensor monitoring on smartphones and tablets. Products run on Windows, Android, and iOS, and are available for a 30-day trial. Listed one-time prices include 59.95 EUR for Extreme, 129.90 EUR for Network Audit, and 219.90 EUR each for Business and Engineer.

y-cruncher calculates Pi and other mathematical constants to trillions of digits, and also serves as a multithreaded benchmark and stress-testing program for overclockers and hardware enthusiasts. For most constants, it uses separate algorithms to compute and verify results. Its multithreading uses modern multi-core processors without significantly increasing memory usage, and it supports SIMD instruction sets such as SSE, AVX and AVX512. For computations that exceed available memory, y-cruncher manages swap space and can use multiple drives for disk swapping. It can detect and correct minor errors attributed to hardware instability or software bugs. Windows and Linux downloads are available; the listed requirements are Windows 8 or later, 64-bit Linux, and an x86 or x64 processor. The Linux static build lacks TBB and NUMA binding, while the dynamic build supports all features but is less portable. The free plan permits non-commercial and academic use; commercial-purpose licensing may be available by contacting the developer. Major algorithm redesigns and rewrites are on hiatus, though maintenance and some processor optimizations continue.
