WinRAR - Single Thread Benchmark is a test variant of the popular compression application WinRAR designed to measure data compression performance using only one processor core (CPU core). Unlike multi-threaded mode, this benchmark focuses on the single-core processing power (single-threaded performance) of a processor. The test process simulates the compression of large files using the RAR algorithm, which demands high efficiency from the per-core architecture, CPU clock speed, and system memory and cache performance.

As it does not use multiple threads or cores in parallel, the results of this benchmark are highly dependent on factors such as clock speed, IPC (instruction per cycle) of the processor architecture, and memory latency. Therefore, this benchmark is a very accurate indicator of how powerful a single processor core is at handling non-parallelizable workloads.

Test results are usually displayed in units of compression speed such as kB/s or MB/s, which gives a realistic picture of system performance in real-world scenarios where many applications or processes still depend on the performance of a single core.

The WinRAR Single Thread Benchmark is very useful for users who want to:

• Evaluate the real-world capabilities of high-frequency CPUs,
• View per-core performance between processor generations such as 11th vs 13th generation Intel Core i5, or AMD Zen 2 vs Zen 3,
• Assess system stability and efficiency in traditional file compression without the aid of parallelism.

Overall, the WinRAR Single Thread Benchmark is an important tool in per-core CPU performance analysis, which is often the deciding factor in older applications, software with limited optimizations, or lightweight tasks that do not require multiple threads. This also makes it a relevant reference in measuring CPU performance for everyday use.
