System Benchmarks (CPU, Memory, Compression, Multimedia)
The AIDA64 suite has various benchmarks for CPU, FPU and memory testing: CPU Queen is an integer benchmark that tests branch prediction and misprediction penalties. CPU PhotoWorxx tests the SIMD integer arithmetic execution units of the CPU and the memory subsystem. CPU ZLib is a compression benchmark that tests the combined CPU and memory performance. CPU AES is a multi-core encryption benchmark that uses Advanced Encryption Standard data encryption. CPU Hash is an integer benchmark that measures performance using SHA1 hashing algorithm. FPU Julia measures single precision FP, FPU Mandel measures double precision FP, FPU SinJulia measures extended precision FP while FPU VP8 is a video compression test utilizing the FPU Julia fractal module.
Using AIDA64 as well as SiSoft Sandra Lite 2015 SP2b, memory and cache performance is benchmarked. Similar to AIDA64, SiSoft Sandra has separate modules for benchmarking and can even compare results to an online database.Benchmarks include latency tests for cache and memory as well as speeds and bandwidth.
MAXON’s Cinebench R15 runs two sets of benchmarks, a processor test for the CPU and an OpenGL test for the graphics processor. The 3D rendering workload is based on Maxon’s Cinema 4D, a program utilized by movie production studios world wide for special effects so it is a semi-synthetic test closer to real-world 3D graphics benchmarking.
PCMark 8 simulates typical home-related workloads including web browsing, gaming, photo editing, video chat and productivity. Like Futuremark’s 3DMark, a numerical score is generated from the combination of semi-synthetic tests. AMD’s A0-7850K can take advantage of OpenCL acceleration to accelerate the performance.
x264 is a popular free software library for encoding video streams into the H.264/MPEG-4 AVC format. x264 FHD measures how efficient a system is in encoding H.264 video and produces results in frames-per-second. H.265/HEVC video encoding is the future of video able to compress significantly larger resolution videos including 4K and make streaming feasible. The downside is that hardware support is still few and far between so processing requirement is steeper than current H.264/AVC standards. x.265 is an open-source implementation of the H.265 standard and x.265 HD benchmark tests the CPU’s ability to process an HEVC video.
Handbrake is free open-source video transcoder that can convert various video file formats to compatible video files for other typical media viewing applications such as in an iPhone or Android tablet. A 52:55 1.1GB H.264 MKV file was used converted to the built-in iPod Preset (5G Support), then manually timed. The results are in seconds and the lower number is the better result.
7-zip is an open source (GNU) compression program utilizing LZMA method as the default. WinRAR on the other hand is a Windows version of a popular compression software created by Eugene Roshal in 1993, widely used for its flexibility. Both have built in benchmarks that measure the system’s compression and decompression capability.
