AIDA64 offers dedicated microbenchmarks, which are available under the Benchmark category in the Page menu. These are synthetic benchmarks, which means that they can be used to measure the theoretical maximum performance of the system. Memory bandwidth, CPU and FPU benchmarks are built on the multi-threaded AIDA64 benchmark engine that – since AIDA64 Business v4.00 – supports up to 640 simultaneous processing threads and 10 processor groups.

Thanks to AIDA64's huge reference result database, benchmark results can be compared to those of other configurations. By clicking the “Results” button on the toolbar, we can save and manage our benchmark results, and we can also hide reference results and user results, which are listed on the results page by default.

You can read more about each test on the following page: Benchmarking

Memory read, write, copy and latency

Memory benchmarks measure the maximum bandwidth achievable when performing the selected operations (read, write, copy). The memory latency benchmark measures the time it takes for data to arrive in the integer registers of the CPU after the issue of the read command.

CheckMate (new in AIDA64 v7.35)

This simple integer benchmark focuses on the CPU's branch prediction capabilities and branch misprediction penalties. It calculates solutions for the classic “N queens puzzle” on a 16x16 chessboard.

CPU Queen (retired in AIDA64 v7.35)

This simple integer benchmark focuses on the CPU's branch prediction capabilities and branch misprediction penalties. It calculates solutions for the classic “N queens puzzle” on a 10x10 chessboard.

CPU PhotoWorxx

This integer benchmark measures CPU performance with several 2D photo processing algorithms. The test mainly stresses the SIMD integer arithmetic execution units of the CPU and the memory subsystem.

CPU ZLib

This integer benchmark measures combined CPU and memory subsystem performance using the public ZLib compression library.

CPU AES

This integer benchmark measures CPU performance using AES (Advanced Encryption Standard) data encryption.

CPU SHA3

This integer benchmark measures CPU performance using the SHA3-512 hashing algorithm.

FPU Julia

This benchmark measures the single precision (or 32-bit) floating-point performance through the computation of several “Julia” fractal frames.

FPU Mandel

This benchmark measures the double precision (or 64-bit) floating-point performance through the computation of several “Mandelbrot” fractal frames.

FPU SinJulia

This benchmark measures the extended precision (or 80-bit) floating-point performance through the computation of a single frame of a modified “Julia” fractal.

FP32 Ray-Trace

This benchmark measures the single precision (also known as 32-bit) floating-point performance through the computation of a scene with a SIMD-enhanced ray tracing engine.

FP64 Ray-Trace

This benchmark measures the double precision (also known as 64-bit) floating-point performance through the computation of a scene with a SIMD-enhanced ray tracing engine.
